"FAILED" flashing factory images

I'm having issues flashing factory images for 5.1.0 LMY47D & LMY47E (tried both) from my ubuntu box. Every time I try these images, I see this:
Code:
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
and then end up with:
Code:
sending 'system' (1736396 KB)...
(bootloader) Data size exceeds download buffer
FAILED (remote failure)
Boot loader on "Device is UNLOCKED Status Code: 3" and I've updated fastboot to the best of my knowledge, using Android Studio SDK Manager, as well as ran apt-get update. Bootloader version is moto-apq8084-71.08. I did an md5sum on the .tgz files and confirmed I'm not getting a bad download on either. After extracting I removed the -w from
Code:
fastboot -w update image-shamu-LMY47D.zip
in the flash-all.sh file, really would rather not wipe, but if someone tells me there's a valid reason I need to, I'll do it. I do not have encryption turned off.
This leaves my phone in an unusable state due to the partial flash, so I'm about to FDR it, but was hoping someone could help first.

Have you tried flashing each image manually?

That was a good idea, just tried it. no dice:
Code:

I just read something about how I might need to use mFastboot made by motorola... trying that now

You have to unzip. Fastboot flashes IMG.
When you download the factory image you unzip, should leave you with 2 image files and another .zip. You have to unzip that as well. It contains the rest of the img you need to manually flash.

yeah, sorry realized that seconds after I posted... edited my original post, sorry for thread confusion.

So after a few other mistakes I'd rather not own up to, I figured out that yes, mFastBoot was the solution to my issue. I'm not sure why I can't find any other folks posting about needing it for 5.1 builds on the the N6, but I did. I never needed it before 5.1, but I'm assuming the system.img file has grown larger than the standard SDK fastboot supports. I'm wondering if this is only an issue when flashing from linux. Theoretically, it should not be though; this issue is based on the memory available on the device (tmo N6, btw).
For those that don't know, "mFastboot" aka Motorola Fastboot is a tweaked version of fastboot provided by Motorola. It will actually split up the image and flash it in pieces.
Here are Instruction for installing and using mFastBoot to flash a Moto G on linux, but the process is the same, except for the images obviously. You'll have to either modify the flash-all.sh file or do each of the images manually.
Hope this helps someone else... it would be really weird if I'm the only one that runs into this.

just fyi, fastboot works fine with all the factory images google puts online but you have to use the latest version. it's available as part of the Android sdk and is included with Android studio.

Thanks, but if you read my original post you'll see I did that and more. Not saying you're wrong, but unless someone can tell me specifically a step in that process I apparently missed, I think there might be exceptions to that rule.

I see now that you're on Linux, I use a Windows box so that's probably the difference. glad to see you found a solution.

On Windows with virtually the exact same issue. I went back to 5.0.1 but the bootloader is stuck on the newer version and can not be modified. I do not use ADB manually anymore. I use toolkits these days and then try manually. Now I'm stuck on 5.0.1 and can not update the OS at all. I get some message when attempting to ADB-Sideload the 5.1m T-Mo OTA saying that "a file located at dev/block/msm.... Has been changed to R/W. Reflash and reboot to regain OTA privilege."
Only issue is I am on a LRX22C Factory Image with Stock recovery. Any help or questions will be welcomed.

I'm not a T-Mobile guy but based on the posts I've come across, the radio in the M update is 95R. since you can't take the OTA now with the boot loader issue, one option may be to flash the D or E factory image to get back onto 5.1. either way I think you want the 95R radio included with D, not the 98R included with E. I have to believe the M update will be released as a factory image at some point or something newer will be released.

You're not alone. I spent over 11hrs trying to get one or the other to flash too using a Mac with OS v10.10.2 and had the exact same issues. Found an mfastboot and was able to flash the images separately (flash-all.sh still failed).
Glad we're both all set... Now to delete the Android SDK and Java files!

Have you tried using mFastboot (just google it the windows exe is easily found)? You'll need to use that and flash each .img separately.

THANK YOU
I've been working with this off and on for some time, and your post was immensely helpful.
Latest fastboot drivers, latest ADB (truly the latest, not just apt-get-whatever). Same issue - system.img would not flash. Not with a script, not standalone, not in the zip file, nothing. What I see (almost constantly) is a buffer issue where the actual size of system.img is throwing a significant error with fastboot drivers. mFastboot (as you provided) on the other hand, utilizes a component called "sparse-flash", which appears to break large files into smaller (256mb) chunks that for whatever reason my N6 preferred. No issues with flashing after that, but again it must be done individually (system, boot, radio, etc.) - never as a zip with "-w update".
I find it curious that so few people have this issue (others can use the "normal" fastboot with large system files and no issue occurs). Those who do run into this problem seem to know their way around a terminal, so it makes me wonder what the underlying difference between us is.
For the record, I was on a machine running Mint 17.2, which is essentially Ubuntu 14.04.
Just really wanted to say thank you and hopefully promote the thread a bit to help others. Especially as many of us are flashing to bone stock momentarily to properly activate Project Fi.

@caain,
A couple of points/questions:
1) You mention having the latest fastboot "drivers". I'm not sure what you are referring to, but I've never heard of such a thing on Linux.
2) Where did you get ADB and fastboot from? Did you download the latest Android SDK?
2a) The point here, is that Google updated fastboot in November of last year to enable flashing the very large system.img from Lollipop. You can only get this necessary version of (if your are running Linux) fastboot via the Android SDK.... And without it, you can not successfully flash a Lollipop system.img.

You can flash the system image manually with fastboot. Can't fastboot flash the flash-all.bat without SDK 23+ platform tools. System image will fail. The 15 second adb/fastboot is not updated to achieve this. Not sure about Linux but if have latest SDK updated it will do the flash-all.bat.

none
I flashed M just to check it out, but prior to doing that I grabbed the SDK that had very recently updated to include the 6.0 M files, so I updated the 6.0 SDK prior to trying M, and when I went back I had zero issues with the flash.bat The only issue I had which was more of a pain than a problem is that flashing the factory image it unrooted the phone so I had to completely set up the phone all over again.
No more M for me until it's released because in the preview 3 not every component is functional, why they would do that I have no idea, so after learning that M wasn't complete I abandoned it. Hope this helps if you want to go back

I suppose I use the word "drivers" a bit too flippantly, as you are correct and there is most certainly not a fastboot "driver" for linux. Perhaps the issue I was running into is that I was merely installing ABD and fastboot standalone, without including the entire Android SDK. In which case I ought to feel quite foolish!
Thank you for the clarification regarding the patch from November. I've no need for fastboot in the immediate future, but will certainly make sure install the SDK as a whole rather than pulling tools from other repositories in the future.

That's a very good idea. I would suggest doing this soon, so it's set up and ready to go when you need it.

Cannot install TWRP on Mi Mix

Hi!
I recently bought a Mi Mix and want to flash it with Lineage OS.
I followed all relevant instructions - did unlock the bootloader and so on - but I am not able to install TWRP using ADB and fastboot.
The phone is connecting well in ADB - even the "fastboot flash recovery twrp.img" gets a positive response - all seems to work fine. But after rebooting, I am always confronted with the stock recovery - the flashing so seems not to work out of some reason - TWRP gets removed during the reboot process.
I also tried to first flash and then use the "fastboot boot twrp.img" command. This command starts TWRP, but only in a frozen state - TWRP then starts in a way that you are not able to interact with the interface. Also here - after rebooting the stock recovery is there again. Can someone give me a hint, how to solve this problem?
I am running ADB on a Linux Computer (Debian 9) - dont think, that this might cause issues, but maybe....
The phone runs the MIUI-Version "MIUI Global 9.1 Stable"
It would be great, if someone here could help me out. I am somehow stuck and dont know how to proceed..
Thanks for taking the time!

You can find two compatible versions of TWRP here.

Thanks Gavin!
Just out of curiosity - can you explain me, why the official TWRP Versions are not working and the ones you did post are good?

Touch has never worked on the official versions to my knowledge. Even the latest 3.2.1.0 build still has broken touch. It is still usable if you use a USB adapter/mouse, but not via touch.

Dear Gavin! Your TWRP file worked great.
But I have no another issue that seems to be common with the Mi Mix - the media sound is not working anymore. Notification and phone works fine but music and video is gone. I just was reading that you should update the firmware. Are the other files added in the link you did send by chance the relevant firmware files?

I was looking for that as well! Thanks for sharing. I can confirm that this TWRP version works well with the Mi Mix.

Thanks guys - the device works fine now. You saved my day!
There is one thing left. I still cannot initiate TWRP manually - have to use ADB for this. Once TWRP is started, I cannot reach the devices harddisk anymore from my computer. Thats no issue now, but might cause issues in the future. Any idea how to solve this?

No. It happened with my device as well. You cannot mount your internal storage on your PC. I've tried many different versions of TWRP and none have allowed access. I'm not quite sure why ... I had other devices in the past and it always worked. On the Mi mix however, it does not. So just turn on your phone and transfer what you need to or adb sideload it.

No. I don't believe that he did James. Does it work for you? because it never worked for me either. I've tried all the different versions of TWRP and it didn't do a thing. Also I have no passwords or encryption. I'm sure of this. Maybe I'm also doing something wrong and that's why I can't Mount my internal storage while in TWRP recovery?
I don't use the official TWRP because for some reason the official versions of TWRP offered for the Mi Mix are broken. The touchscreen never works and I don't have an external controller or anything else to make it work other than the phones screen. So I've used the custom versions that have been fixed and re-released on XDA.

That's very odd. I'm not quite sure what to tell you. I know for a fact though that my device is not encrypted. I'm currently running RR without any password/pattern. Before installing RR I was on stock OS and still no password/pattern. I live alone and so I don't feel the need to use a password on my phone. So ever since I've purchased this phone I've never had a password on it.
No updates as far as I'm aware on the RR.
Does it Mount for you? If so, what TWRP are you using on your device?

I've used the same 1 from the beginning, smarty, I just followed the guide in the guide section how to remove vendor ROM. I use Linux it works fine.

Wow. Well you're lucky tbh. I can't seem to figure out why mine doesn't connect. I'm not sure what the difference is between the vendor (ROM) and the "stock" (ROM) - I know I was using the global stable (ROM) that's what my phone first came with and it was running 6.0 MM.
Yes, I have tried to use MTP while in TWRP and it doesn't do anything. My computer does detect something but doesn't show the phone to be connected or anything. I have even tried to mount it in the options but nothing. I know I have all drivers installed and does not make a difference. I'm running Windows 10 not Linux.

Honor magic 2 magisk root guide

Just in case you didnt know ive wrote this guide to help root your honor magic 2 model (TNY-AL00)
first you must have your bootloader unlocked and huawei does not give BL unlock codes anymore so youll have to get it from a third party source and they charge money for this service, i know it F**kin sucks but i havent found any workaround for this, i used funkyhuawei and it was 55 usd, they were quite quick with getting me the code and i cant use a phone without full control so it was worth it to me, ive heard of cheaper alternatives like ministry of solutions but i do not know the validity of this.
Second, you must find an update.zip firmware for TNY-AL00 which i could only find on easyfirmware.com which again they freaking charge money but look around you might be able to find free firmware someware, as far as i know at the time of this writing the huawei firmware finder app does not have the new models yet. Find this firmware and download to a pc "and yes you can use a lower version than the one your running as i used a .129 RECOVERY_RAMDIS.img and my system is on .150 and i havent run into any problems as of yet"
Third, download huawei update extractor on pc run it and in settings make sure the first two boxes are unchecked. Open update.zip with the extractor and extract RECOVERY_RAMDIS.img from it and transfer it to your phones storage
Fourth, magisk now supports emui 9 rooting but at the time of this writing its only available on the canary build,
To get to the canary version of magisk download and install magisk manager then ignore the install prompt magisk gives you when you run it and then go to settings and hit update channel and choose custom and paste this "https://raw.githubusercontent.com/topjohnwu/magisk_files/master/canary_builds/canary.json" and restart magisk and itll ask you to update, update the manager then when it asks to install magisk.zip go to install and patch boot image " make sure magisk version is on 18.1 not 18.0" and patch the recover_ramdis file on your phone. The patched boot image will be in the download folder of your phone, use pc and transfer the patched boot image to desktop on pc
Fifth, download minimal fastboot and adb drivers to yor pc and run command prompt, connect phone to pc and and run phone in fastboot mode " press and hold volume up right after pluging in usb from pc to enter fastboot" in command prompt type fastboot devices and it should show some numbers which means it recognizes your phone, now type "fastboot flash recovery_ramdisk /path/to/RECOVERY_RAMDIS.img" or just drag the RECOVERY_RAMDIS.img into command prompt after typing up to recovery_ramdisk
Then type fastboot reboot and get your phone to power down, to have root you now have to hold volume up and power to boot. You have to do this every time if you want root. Your now rooted..........

That's unfortunate. Ny biggest reason for rooting would be to get better camera support. I dont suppose GCam works on this with a root? I don't see any ROM development for it either. Why did you decide to root?

Yes this is tryed and true method. I get it working on my phones first then i post guide, everything works fine, only thing ive noticed is sometimes itll take a min for magisk to ask for grant to su from app or service.

Tnx for sharing the info!
I'm considering trying the process and maybe attempt to build a TWRP image if rooted successfully.
Is your device still working properly?
Did you accept OTA updates and would you use the exact same steps and files if you were rooting today?

No ota
You have to reflash the original ramdisk.img to update then flash modded ramdisk.img

I'm considering buying this but only if it is rootable. Is it possible to install wearOS afterwards (soc compatibility ?)? Thank you very much

[GUIDE] Unlock bootloader, root the device and install any custom ROM! (ALE-L23/21)

Hi all! So, you have a P8 lite in your pocket and you hate EMUI? Well, that was my case too, it's uncustomizable, ugly, and removes plenty of features from android stock. I do not like it one bit, and I like even less the fact that this phone is getting no more updates, ever. This sucks, it all sucks, luckily we can say "F all that" and do whatever we want with this device, provided you follow this guide.
I am making this guide because I want to condensate every single thing I know about this device in one single thread. One big guide to help all of you out installing custom ROMs. Without this, you would have to do research along multiple threads, often with conflicting information, and what's even worse, DEAD LINKS! There's nothing more frustrating than finally finding the solution to your problem, just one download away, just to be greeted by a dead link, and you would need to scout for another file that may or may not work... ugly stuff.
So, the point of this is to bring up to date info so you can make this device rock. This guide assumes you have Huawei's EMUI 4.0 installed which runs on Android 6.0. I'm also assuming you have your bootloader locked, and I will explain how to unlock it FOR FREE. No need to pay to some shady site in order to access what effectively belongs to you.
These are the requirements for this guide:
Code:
#USB cable
#A PC
#Some charge on the device to ensure nothing goes wrong
#An SD Card
#Patience
Before beggining, a quick disclaimer:
Code:
#It's not my objective to break your device, however there's always a risk when doing these kind of things.
#When you follow this guide's steps your are accepting the risks and are taking full responsiblity for whatever may happen to your device.
#Don't blame me for breaking your stuff if that happens, all I'm listing here worked for me, and should work for you.
#I won't be babysitting anybody to help solve their specific problems, don't PM me asking me why X doesn't work.
#I am unaware if this works in other versions of this device, but I'm positive this works on both ALE-L23 and ALE-L21
#If you have a "CAM-XXX" device, it's highly likely this works for you too, but as with everything, TRY AT YOUR OWN RISK.
#YOU HAVE BEEN WARNED!
Ok, so let's begin. As the title says, the guide is applicable to any custom ROM. However, I will be installing Lineage OS 14.1 which runs on (almost stock) Android 7.1.2. Regardless, the final step where we install the custom ROM is interchangable, and you can use whichever you please.
This process WILL wipe all of your data (except SD card). Make sure to make a backup of everything you want to save (app configs, photos, videos and whatever else).
1. DOWNGRADING TO ANDROID 5
As you may know, Huawei has stopped providing bootloader unlock codes for very stupid reasons. This has led to many unable to unlock their bootloader and having to pay for third party apps in hopes they don't get scammed. There are some trustworthy sites where you can get these at a fee tho (mainly DC Unlocker at 4 bucks), so if you want to pay up to avoid having to downgrade to Android 5, you can do so. However, I understand that you may not want to pay at all, I didn't want to either.
To get the bootloader unlock code, we need root, and to get root, we need Android 5. Why? Because getting root in Android 6 requires us to flash some zips, and for that we need TWRP, and for that we need an unlocked bootloader, everyhing closes up very nicely. So, we have no choice but to downgrade.
An SD card is not needed for this process, but it is going to be required at a later point, so why not use it now too?
NOTE: It may be a good idea to make a factory reset at this point, to avoid issues. For that, do the following:
Turn your phone off.
Boot the phone by holding the power button and the volume up button at the same time.
Wait untill the Huawei logo appears, then let go of both buttons.
You should be in recovery mode, navigate with the volume keys to the "Wipe data/factory reset" option.
Select it with the power button and wipe everything.
Reboot the device with the option in the menu.
Once the device has booted up, follow the guide.
Alright, once that's done, connect your phone to the PC to transfer some files:
NOTE: There's two Stock Android 5s downloads ("HW_Android_5_Transition.zip" and "HW_Stock_Android_5.zip"). One is a transition package, as the name implies, and the other is Huawei's EMUI 3.1 in all of it's glory. What's the difference? The transition package is a much smaller file that is designed to downgrade the phone from EMUI 4.0 (Android 6) to EMUI 3.1 (Android 5). If you are running EMUI 4.0 (which should be the case) then you can use the transition package which will take less to download. If you have another version (i.e. EMUI 4.1) you should use "HW_Stock_Android_5.zip". However, the latter is the safe bet. If you are not sure which one to use, use "HW_Stock_Android_5.zip". The process is exactly the same for both packages.
Extract the "UPDATE.APP" file from "HW_Stock_Android_5.zip" or "HW_Android_5_Transition.zip".
Navigate to your phone's internal memory or SD card (whichever you want to use) and locate a folder called "dload". If there's not one, create it.
Put the "UPDATE.APP" file inside of the "dload" folder.
Turn your phone off.
Once it's off, press the power button and the two volume buttons until you see the Huawei logo.
That should make the phone recognize the "update" and start flashing it. Once it finishes, it will try to boot by itself, so pressing those 3 buttons was your last input until the phone boots into Android 5. It will take a long time for it to both finish and boot, don't be afraid, the phone is not bricked. If you think the phone is indeed bricked because it has been stuck at the logo screen for way to long (longer than an hour) then proceed to the "Unbricking" section of this guide. However, it's highly unlikely that this will happen, as Huawei checks the file before flashing it, so if it's incompatible with your device it should not do anything and boot again into Android 6 with everything untouched.
2. ROOTING ON ANDROID 5 AND EXTRACTING BOOTLOADER UNLOCK CODE
Once you are in Android 5, we will need to root the device. Download KingRoot (proved to work) or another one click root app of your choice. I'm aware of KingRoot's bad reputation because of the spyware accusations, but the phone will be wiped anyway and we are sure it works, so it doesn't really harm at all. If you still don't want to use it, check with other apps, I haven't done so myself so I don't know what else works.
Once your phone is rooted, we will need to use the terminal for the first time. We will need to setup ADB and Fastboot, if you already have that, skip this step.
Extract the "platform-tools" folder from the zip and place it somewhere nice.
Shift right click on a blank space INSIDE of the "platform-tools" folder.
Select "Open command window here".
This should be enough to get ADB working, but we need to make some config on the phone itself too.
Go to Settings -> About Phone
Look for a line that says "Build Number" and tap it multiple times.
When the message saying "You are now a developer" pops up, go back and enter the new "Developer Options" menu.
In there, look for an option called "USB Debugging" and turn it on.
Connect the phone to your PC via USB cable.
A message should have popped up on the phone asking for permission to use USB Debugging, tap on "Always allow from this PC" and then on "Allow".
NOTE: If the message doesn't pop up, you can try a number of things. I prefer to tap the "Revoke USB debugging authorizations" button to ensure that no PC is authorized, so the message must pop up at some point. Once you revoked authorizations, disconnect and connect the phone again, if you still don't see it, try to select MTP as the transfer protocol. If not, then PTP, if you still don't see it install Hi Suite on your PC and open it, it should pop up now.
Once you have everything working, type the following in the terminal in your PC:
Code:
adb devices
If you see a serial number there, that's your phone, and that means everything is set up correctly (make sure you don't have any other device attached to your PC, or you could confuse the two and make bad stuff happen for that other device). If you don't see it, make sure USB Debugging is enabled. You can try to use different cables if you still have problems. Now type:
Code:
adb shell
And then:
Code:
su -c "grep -m1 -aoE 'WVLOCK.{14}[0-9]{16}' /dev/block/mmcblk0p7 |grep -aoE '[0-9]{16}'"
KingRoot (or the app you used to root) should prompt you (in your phone) if you want to give ADB root access, make sure to allow it to make this work. This should give you your unlock code. SAVE IT INTO A TXT FILE AND COPY THAT FILE TO ALL OF YOUR PCS, ALL OF YOUR CLOUD ACCOUNTS AND ALL OF YOUR MOBILE DEVICES.
(Maybe the terminal gets stuck at this point, press CTRL + D (or C) to get it unstuck).
Seriusly tho, it didn't happen to me, but it is a possibility that your Bootloader can re lock after doing some of the things that follow, in which case you will need to unlock it again, and if you don't have that code... it's back to square one.
3. GOING BACK TO ANDROID 6
Now that we have done all that we wanted on Android 5, it's time to go back. The process is exactly the same.
Extract the "UPDATE.APP" file from the "HW_Stock_Android_6.zip" file and move it to the dload folder (SD card or Internal).
Turn off your phone and turn it on again with all three buttons pressed.
Wait.
???
Profit.
So, we're back on Android 6. Why did we go back you may ask? Why did we not just flash our precius custom ROM? Well, for once, this gives people the chance to stay on EMUI if all they wanted was to unlock the bootloader and maybe root on Android 6 (which I will explain how to do too, in case you want to). Another, more important reason, we need Android 6 to install the B895/B896 update, which is a requirement for any custom ROM (mainly Android 7.0+) if you don't want any problems with your SIM card (and others that may arise).
4. UNLOCKING BOOTLOADER AND FLASHING TWRP
Now, we need to turn on USB Debugging again, and to allow our PC... again. Do so, and check that everything is right with:
Code:
adb devices
If that's the case, then type the following:
Code:
adb reboot bootloader
Your phone will reboot, and you should see a white screen with a wasted android above a green text saying "PHONE LOCKED". If that's the case, take a moment to say goodbye to that green text, because it will soon turn very red. We will need to unlock the bootloader with the code you got from the previous steps, for that type the following:
Code:
fastboot oem unlock ****************
In place of the "****************" you must enter your code, of course. And that was it, now the green text is replaced with a red "PHONE UNLOCKED". This are good news. Now, we need to flash our custom recovery if we want to do anything fancy with the device. For that, extract the "recovery.img" file from the "TWRP_3.1.1.zip" file and paste it into the same folder where all of the ADB files are located (where "adb.exe" is). Now type:
Code:
fastboot flash recovery recovery.img
This will flash TWRP into your device, hooray! Now type:
Code:
fastboot reboot
And your device should turn back on, today is a bright day my son. Now you must take a decision, do you want to flash a custom ROM and get very nice and fancy features or do you want to stay with what you have? If you prefer Huawei's EMUI 4.0, then follow to the next step. If you want to flash custom ROMs, then skip the next one.
5. ROOTING ON ANDROID 6 (OPTIONAL)
I don't know why you would prefer EMUI over... anything else really, but it's your call. I'll tell you how to root it so you can at least take some advantage of it. You see that file called "HW_Android_6_Root.zip"? Extract it, inside there will be... another folder called Root... huh? Redundant. Anyway, inside of that there should be two zips. 1.zip and 2.zip. You will need to place the folder called "Root" inside of your SD card or your internal storage. Then, go back to the terminal and type:
Code:
adb reboot recovery
You should reboot into TWRP, isn't it nice? Anyway, we have to flash some zips! Go to "wipe" first and wipe the "Cache" partition and the "Dalvik" partition. Once that's done, go to install and navigate to the Root folder your placed... well, you know where. Select 1.zip and flash it, once it's finished reboot the device. If TWRP prompts you to install it's app, DO NOT DO IT. Once the phone has rebooted (it will take longer because of the cache and dalvik wipe), repeat the process but flash 2.zip this time, reboot and your phone should be rooted. This is the end of the line for you now, as you don't want to make anything else to the phone. However, you can go to the final chapter where I explain how to install Xposed framework, if you want more customization. EMUI doesn't like Xposed very much, so there's little you can do with it, but it's something I guess.
6. INSTALLING THE B895/B896 UPDATE
So, you followed the power user path, the one we all really want deep down. That's cool, I respect you. We gotta use that custom recovery we just flashed, but first we need to transfer some files into our phone's memory. We need to install an update to the phone, for which you need Android 6 (that you should already have anyway). There's two different updates, B895 and B896. As you may guess, B896 is newer. However, any of these two will (or rather should) work without issues. I personally used B896, but some people claim B895 is more stable. I can't find a difference really, but the process is the same regardless of which you choose. Once you have made that decision, move "B895_update.zip" or "B896_update.zip" to your phone's internal storage or SD card AS IS (don't extract it). Then type into the terminal:
Code:
adb reboot recovery
You should be in TWRP now. Go to wipe and select the "Cache" and "Dalvik" partitions ONLY, then wipe them. Once that's done, go to install and flash your update of choice. Once finished, reboot the device. If TWRP prompts you to install it's app, DO NOT DO IT. The boot should take longer than usual because of the "Cache" and "Dalvik" wipe... and because of the update too. Once booted, you should be in EMUI 4.1. Go to settings and into "About Phone". In there, look for a field called "IMEI". If you see a number, that means you did everything properly, if you see "unkown" or nothing at all, then that means you lost your IMEI... which means you will have connectivity issues. To fix this, you will need to do a full wipe (so, boot into recovery (we lost TWRP due to the update) and then go to wipe, in there select everything except SD card) and follow the steps again starting from 3, this time flashing the other update (so if you flashed B895, flash B896 this time and vice versa)).
Now, this last step we made has wiped our custom recovery... so sad. We have to flash it again, but we are almost finished!! Now it's time for you to move the custom ROM you want to your SD card (SD card is mandatory, as we will wipe internal storage). You should also move your custom ROM of choice. If you want root, also move the "SuperSUv82.zip" file.
OPTIONAL:
If you want Gapps, that means the Google apps, so PlayStore, Google services and such (and you really should want them, as Android without PlayStore is kinda rough), then you need to download them separately.
So, go to the Gapps website and select the pacakge you want. You NEED to choose the ARM64 platform, the android version depends on the ROM you are flashing, so check which version it runs, and the package itself is personal preference. Here you can see a comparison of each package, detailing what each one contains so you can make a decision. The aroma package is kinda bugged, I would avoid it. Choose wisely, as flashing another Gapps package once you have flashed a different one can and most likely will cause issues. If you want my opinion, I would stick to the nano package. It offers the basic Google functionality and allows you to download other Google apps you may need/use with the PlayStore once you are booted up.
Once you choose your package, move it to your phone's SD card along with the ROM and the SuperSU zip if you want it.
Check that USB Debugging is still enabled, and then type:
Code:
adb reboot bootloader
Once into the bootloader, flash the custom recovery once again with:
Code:
fastboot flash recovery recovery.img
Then:
Code:
fastboot reboot
Once booted up again, type:
Code:
adb reboot recovery
And now it's time to drop the bomb, say bye bye to EMUI, and say hello to... whatever it is you are installing.
7. FLASHING YOUR CUSTOM ROM OF CHOICE
MOST CUSTOM ROMS REQUIRE AN LTE CAPABLE SIM IN ORDER TO HAVE CELLULAR NETWROK WORKING CORRECTLY, THIS DEPENDS ON A ROM TO ROM BASIS, DO YOUR RESEARCH BEFORE FLASHING
Once in TWRP, go to wipe and check every box, I'm serius, check everything except the SD card. Once that's finished, the moment of glory has come. Go to install and flash your ROM. It will take a while, and when that's done reboot. The phone should boot into your ROM. If you want either Gapps or SuperSU, make a quick setup and enable USB Debugging again, then reboot to recovery with:
Code:
adb reboot recovery
Once in TWRP, go to install and flash the Gapps package and the SuperSU zip (in that order) if you want it. Reboot. That should be it! You are done!
8. UNBRICKING
I don't know why, but with all the flashing and the testing I've done you would have thinked that I should have suffered of a brick state at least once... that was, luckily, not the case. I haven't suffered a single brick. I don't know if I'm extremely lucky or if this phone is tremendously resilient, but the case is I haven't had any issues of this kind.
However, I can understand that it is a possibility, so if this happens to you my best advice is to do the following: Boot into recovery mode (either stock or TWRP depending on where in the whole process you got stuck), make a full wipe and apply the update from "HW_Stock_Android_6.zip" with the dload folder and the three buttons method. That should get it unstuck, if not... try the same with the "HW_Stock_Android_5.zip" 's "UPDATE.APP".
9. INSTALLING XPOSED FRAMEWORK (OPTIONAL)
What? A custom ROM is not enough for you? Getting freed from EMUI is not enough? Well fear not then, because there's one last step for the true power user, for that man who thinks that everything is not enough, the good old Xposed Framework *queue fireworks and trumpets.
So, you need to install the Xposed Installer apk. Get it from here, and ONLY THERE. I once installed an apk from another source... ended up being adware, not fun. The apk is at the very bottom of the thread. You will also need the framework itself, get it from here.
Get the latest (arm64) version for your ROM. This depends on what Android version it is running on:
Code:
SDK21 = Android 5.0
SDK22 = Android 5.1
SDK23 = Android 6.0
SDK24 = Android 7.0
SDK25 = Android 7.1
SDK26 = Android 8.0
SDK27 = Android 8.1
You should also get the uninstaller in case things go south.
Once you got the files, install the apk on your phone. Open the app once. Transfer the framework and the uninstaller into your SD or internal storage. Boot into TWRP recovery and install the framework, reboot the device.
NOTE: Android 6.0 takes about 20 mins to boot, wait about an hour before deciding that it's bricked. Android 7.1.2 took me about 2 mins. I'm unaware of the boot times of other versions, but be aware that it can take LONG. If you think it really got bricked, boot into TWRP again and flash the uninstaller. That should get it unstuck and you can either try again or leave it as is.
----------------------------------------------------------------------------
Well guys, that's all I got, quite a big write up huh? I don't really have nothing else to say, just remember that what you are doing here is at your own risk and I don't want anybody blaming me for the bad things that can happen. I will proceed to leave you with the download links so you can try this yourself. I'm currently running Lineage OS 14.1 which features Android Nougat 7.1.2 on my Huawei P8 lite ALE-L23, I've never been happier to be free from the manufacturer's ROM.

Hi,
I didn't understand what do you mean whan you write: Once booted, you should be in EMUI 4.1. If you retained your IMEI, you are in good path, if not... then do a factory reset (wipe everything) and repeat the steps starting from 3.
Could you explain it better?
Thank you

Yes, it's basically this: If you go into the "About Phone" section you will see that there's a field detailing your IMEI. I won't lie, I don't know exactly what it is, but it's a unique number for every phone and has something to do with your cellular network connection.
If you messed up at some point, you can lose your IMEI (i.e. you won't see it in that field or it will say "unknown" or something of the sort). If that happens, then it means you did something wrong, and proceeding in this state will make you have problems with your connection. The signal would be really unstable and it would be practically unusable.
To make a simpler check, if you have a cellular network connection, and can make calls and send/receive SMS on EMUI 4.1, then you won't have any problems.

Ah ok it wasn't so clear but I know what an imei is luckily it didn't erase it in my case. Anyway, I don't know how to thank you bro! You saved my life. I beleived to be screwed when I learned that Huawei stopped releasing the bootloader unlock code. How stupid they are. I blamed them through the customer support. I'm running lineage now! Kiss my ass Huawei!

Thanks <3 -notes
Thank you tralph3, you make my life so easy, great easy guide. I have a few suggestions for improving clarity:
Step 1. "Stock_Android_5.zip" contains "transitional" android 6.0 ALE-L21C900B500 firmware According to including Spanish documentation "3., 3.1 Download the Android5.0 update package" It must be downloaded another 5.0 firmware. I use this 5.0 firmware to make kingroot preform root.
Firmware: huaweidl.com/download/p8-lite/ale-l21/b204/
Look for a line that says "Compilation Number" and tap...

Thanks for pointing this stuff out, I'll make those changes you suggested and try to fix some typos too. So, what I gather from what you told me about that Android 5 thing is that in order to correctly flash the update I'm providing you NEED to be in Android 6, right? Whereas with the one you are providing me it should boot into Android 5 regardless of what you currently have. If that's the case, I'll include both and tell people of the distinction between the two so they can use the one they want/need (after all, the transition package is much smaller and easier to download). I'll download the package and upload it to Android Filehost along with everything else. I think I'll keep the mediafire downloads as a mirror. I'll get to that, thanks.

Yes, exactly. Thanks for curating this additional download, good idea.

Does this also work for the PRA-LX1 version?
I have Android 8.0 on it and absolutely no idea what EMUI version or eben the firmware version.
I want to put crDroid on this phone because EMUI ... you know, it's bad.
Otherwise: I am ok with paying these 4€ if this payed unlock works.
WHICH of all these DC Unlocker Apps do I need for getting the unlock code?

DON'T TRY ANY OF THIS. All of what I've detailed is for the P8 lite 2015, your phone is a different 2017 version that's basically another completely different phone with the same name, because Huawei doesn't know how to namr their devices. You have a different chipset, doing anything of what's described here will most likely brick your phone. With that said, maybe the bootloader unlock method works IF YOU FIND ANOTHER WAY TO ROOT YOUR PHONE. DON'T ROLL BACK TO ANDROID 5 WITH THE FILES I'M PROVIDING PLEASE.
This forum is dedicated to P8 lite 2015, you can see there's a different forum for 2017. Good luck.

Hello, I have ALE-L21 with EMUI 4.0.3 - MM 6.0 - version B633 and i can not downgrade to android 5, phone says : update failed, or stuck on 5%. could someone help me please ?

Are you using the stock package or the transition package? If you are using the transition package, try stock.

I tried both, with no success. And many others.
I tried to update via internal storage and SDcard too, with no success.
If phone is connected to pc, updating stuck on 5%, if not connected to PC, update fails.

Did you wipe all of your data with the stock recovery? If nothing works then I could suggest you to try to apply the downgrade with sideload. (Boot into recovery and select to apply update from adb, then you type adb sideload <filename>)
I'm clueless on why it doesn't work on your device, it should.
Also, you can try to flash the stock android 6 rom first, that's an older emui version (4.0). If you can flash that, then maybe you can flash android 5 after it.

i have tried intalling both the 5.0 stock roms but it always fails at 5%. i got ALE-L21C02B896 with emui 4.1 and android 6.0. i've been trying different guides but all lead me to dead ends. please help
thanks in advance

GUIDE: How to unbrick your Zenfone 6 (ZS630KL)
Hello. This guide will help you unbrick your device in case your devices hangs as it boots, and always boots into fastboot mode and recovery is unavailable and the like. Note: Unlocked bootloader is not required to do any of the actions...

I have a correct firmware .zip file in root path however in Android Fasboot menu I have only following options:
- Reboot system now
- Enter recovery (it just takes back to the previosu menu)
- Reboot to bootloader
- Power off
How to use command adb reboot recovery without using a computer (as stated in first post)?

so maybe you have one of the lastest andoid 12 version and now you can't downgrade
if we don't know which version you have and you try to downgrade it's very hard to help you

My current firmware version is 31.1010.0410.72
I'm trying to downgrade by flashing firmware that is visible in the screenshot in post #2

I have the same problem, A12 firmware version is 31.1010.0410.72 , the phone doesn't pop up a message which detected a firmware update info.
maybe also interesting
(in recoverymode only :
Reboot system now
Reboot to bootloader
Enter fastboot
Wipe data/Factory reset
Run graphics test
Power off)
I do have a PC and adb
Can I downgrade with these instructions ? I'm scared:

Hi
yes , I did that and it worked
But keep in mind that the script used to downgrade will delete ALL files on your phone.
And as far as I know there is no other way to downgrade the OS from 12 to 11.
regards
Bernd

Thanks,
1.can you tell me when you did that that the bootloader was untouched and locked ?
2.can I do something wrong ?
3.Is it better unlock the bootloader and install twrp ?
(the basic recoverymode gives me no possibilty for use an upgrade or adb sideload)
4. I want install /e/ on it , /e/ expect A11 on it
I'm still scared:
I get an answer from Asus:
Usually, the downgrade is only intended for the first batches of Android 12. According to the data you provided, your phone is up to date and you are therefore using the most recent Android 12 version. The downgrade is not written for such a version given that it is now 4 months old and was intended for users at the time where the first upgrade to Android 12 did not suit.
I will check internally for you what the possibilities are, but keep in mind that there is a chance that we no longer offer a downgrade for this version of Android 12.

As far as I know the bootloader is not touched (I'm not sure if downgrading via that script works with a locked bootloader - but I did not test that)

Well, there is always the change that something goes wrong doing this kind of stuff. But regarding the script the only thing you do is starting the script - the script will execute all neccessary steps for the downgrade without user intervention and will only ask for confirmation for the last reboot from the new installed Android 11
But if the script fails for whatever reason you should know how to fix this kind of error before using it.

As far as I know you can not downgrade using the standard installation via TWRP or any other recovery ROM (but that might be wrong - you can try it before using the script ...)

I never tested that OS, probably you should wait for an A12 based version of the OS.

The installation of Android 11 here is only to prepare the phone for another Android 11 based distribution as far as I understand so this can be ignored. But if you stay on the original ASUS Android 11 you should update the OS to the latest version of Android 11 released by ASUS after downgrading.

Yes, the instructions state to download the zip file into the root directory and wait for a few min after rebooting preferably, no need to unzip. However, the person uploading the files seem to be mixing up the file name format for various devices. You need to check which format is compatible for your device : UL-ASUS_I006D-ASUS or UL-I006D-ASUS. The file name has to be EXACT for the update for upgrade or downgrade to TRIGGER. Hope that helps.

Downgrading to Android 11 was possible with either through PC and the developer system image zip or downloading the zip file and letting the phone detect it, though out of the box after updating to A12 the phone didn't detect the zip. I had to go through the PC and run the update_image.bat from the provided firmware.
Problem is, after starting A11, right after getting an internet connection the phone starts downloading and updating to Android 12 automatically. It can't be stopped, or disabled. God damned infuriating, makes me want to return the phone, but I know there are no other options for this kind of phone.
I have no other option than to unlock the bootloader, root, and disable the update apps through adb. At the same time I'm possibly denied warranty. F*cking senseless bull**** that if I prefer to use A11 I can't without problems. Sure the security patches are a bit older, but people make too big of a deal out of them. You aren't instantly getting hacked even with a few year old security patches.
edit:
I have managed to stop the update service permanently in android 11. You need to enable developer options, then connect usb debugging and open an adb shell, which should as for authorization on the phone.
In the shell, type
pm uninstall -k --user 0 com.asus.dm
pm uninstall -k --user 0 com.asus.UpdateLauncher (this might be just the new phone wizard for restoring files etc)
which should return "Success", even without root. I'm not sure if you need to uninstall both of them, or just dm, which is the main update process. In any case, the whole system update section in settings has disappeared. Fine by me, I can install them manually, which is all that I wanted as an option. You can uninstall other packages too, pm listpackages produces a list of them, and you can filter it like "pm listpackages facebook" to show only results with facebook in the name.

Thanks for the tip. I was laughing since I had the same exact frustration as you but unfortunately my way of disabling the update was to unlock and relock the bootloader without any changes to avoid a possible brick. Unfortunately I noticed there is a bootloader lock count and it changed to 1 after I did this so my warranty is now voided most likely since they can tell it was unlocked with the counter. Any particular reason why you choose to revert to A11? Cheers
PS
Fortunately I noticed widevine L1 was still intact after unlocking / relocking bootloader so seems to be unaffected by both instances.

It seems wanting to root your phones is harder and more inconvenient every year. It should really be a simple process that simply allows you to decide what is running or installed on your phone. I can understand the security implications, but that should be all be dealt with a disclaimer. It is now your responsibility to make sure you don't allow shady programs root access, that's it.
With every new phone I get it's more convoluted, there are less roms available, less people on the forums. Driven to extinction because god damned the manufactures don't care about you after they get your money.
Well anyway, my reason was simply that I really really dislike the UI in 12. Doesn't sit well with me at all, and can't get used to it.
I know I'm making things difficult for me but I refuse to accept that garbage and if I want to run 11 for the time being I should be able to. It's the principle.
I'm going to have to root in the end, but just for now I wanted to test drive the phone without too much work if it's going back.

@eboelens have you received an answer from Asus?
@eboelens @bnsmb @Jgruar when trying to downgrade by method from https://www.asus.com/Content/Android-12-Beta/ I'm getting following error "Command not supported in default implementation" and since it worked for you I have a following questions:
1. You were using Recovery mode or Fastboot mode?
2. Have you enabled USB debugging in Developer options? I did.
3. Have you enabled "OEM unlocking" in Developer options? I tried, but I can''t cause it's visible in the search but not in Developer options (looks like a bug).

Hi
the instructions from the Beta Website will only work if the phone is connected via USB and booted into the bootloader (=fastboot mode).
USB debugging on or off should be irrelevant for this action (I did the reinstallation using this method with and without USB debugging enabled)
AFAIK the phone must be unlocked to reinstall via fastboot commands . Unlocking the phone can/must be done with the Unlock App from ASUS:
https://www.asus-zenfone.com/2015/10/official-asus-zenfone-2-unlock.html
regards
Bernd

@bnsmb I have two separated modes - Fastboot and Bootloader (screenshots). Which should be used for update?
Do you suggest there is no way to downgrade from Android 12 to Android 11 without voiding warranty?

I haven't unlocked and did the downgrade through fastboot mode with the A11 image file and instructions from ASUS beta program. If they provide the image freely and don't mention anything about voiding the warranty it has to work without unlocking. Just had to make sure my usb connection was stable, had a problem of corruption during install with one cable.

Make sure your device is visible to the computer (fastboot devices) and is in the fastbootd mode (like in your 1st picture).
You then should be able to excecute the "update_image.bat" file from the package, but I used "update_all.bat". Not exactly sure what the difference is, but someone at some post said to use that. I think the update_image.bat would have worked fine if I had a stable usb connection at the time.
Male sure to disable the update service via the method I posted, or else the Android 11 version will force an install of A12 as soon as it gets a network connection.

Neither of those modes is correct. For me mode from the below screenshot worked.
@Jgruar The version that we uploaded via script is a very old Android 11. How did you update from it to the latest Android 11 version since you have uninstalled update service?
Comment for other people, who just bought Zenfone 8 and are struggling like I did: Consider returning the phone. UI of Android 11 is better than 12, but it's still much worse than Android 8 with Samsung add on (Samsung Galaxy S7). Notification list has ridiculously big margins and the opacity is too big (it's hard to see what's in the background). Also view of last application is much worse (one can see name of only one application - the one which is currently open and in Samsung I could see names of last 5 apps). IMHO using pure android is a pain and it's better to buy some phone with pre installed add on or root the Asus but that's voiding the warranty and costs time.
