[P8 Lite] Updating the huawei p8 lite when it rootes

Hello,what going to append if i update my rooted phone on B136 to B170 because i readed that if i update with OTA Update my phone can go in a bootloop. Thanks for the answer.

It might be possible. Do not update ota when you are rooted. Download the latest firmware from huawei-updates.ru for your specified model, take the zip into your sdcard in a folder named dload ( you can create it if you dont have it) and go to updater, local update and select it.

Thanks ! and like that I'm not gonna have any problem ?
And and I can directly go to B170 or not?

I made that you say but didn't worked ... thanks for the help .

Keep it in that folder and try to force update by powering down your phone and power it up pressing vol up+ down and power button

Thanks it worked !

No problem sir, here to help

Nooo! don't know why but my phone go to a bootloop.... tried everythink....

Hmm, try to plug in it an usb cable and flash an old firmware for it trough adb.

Can you give me some link to do that ? and thanks !

U need adb toolkit, a version of b170, search on huawei-updates.ru , prefferably the european version. Get huawei package extractor and extract from update.app found in the zip of b170, system.img, cust.img, boot.img,recovery.img. and flash them one by one in fastboot mode. If not, if u had a nandroid backup made with twrp u can restore. U can search google on a detailed guide to do that, as I may induce you in error, not a native explainer talent here

Or you can extract it and flash automatically all in one clic with a script(for all firmware )

I got to beta 6.0, installed twrp, root it, but it did not permanently, uninstall some system app (google+, maps, etc) after a few reboots superSU was asking for binaries; so I unroot it.
How can I get back to stock recovery? And if so, If I make a factory reset, would it boot correctly for a new setup (because of the erased apps earlier).
Thanx mates, regards

[Tutorial] Convert Honor 6+ Chinese in European (only PE-TL10)

Today I bring new tutorial to completely convert the Honor 6 Plus Chinese in European. (It's only applicable for the model PE-TL10).
So we must have unlocked bootloader and root. If we meet these requirements, we can proceed with the conversion.
1. Download the latest European version (B571)
2. Create a folder called dload in the micro sd and introduce there the update.app
3. Download the European oeminfo here, unzip and move the oeminfo.img to internal memory.
4. Install the app termux or terminal emulator
5. Open the app and write "su" to get root permissions.
6. Later, write "dd if=/sdcard/oeminfo.img of=/dev/block/platform/hi_mci.0/by-name/oeminfo" and when it finished, turn off the Smartphone.
7. Press Vol-+ and Power to install the European update.app and we will have turned the PE-TL10 Chinese in European.
Neither me or XDA we are not responsible for any misuse of the tutorial. I want to thank @foncubiert to try it

I was looking at it for 1 year, thank you very much. now google hello.

Is there "oeminfo.img" necessary to do the reverse of this process for install twrp old backup?
*** I need "oeminfo" file in China stock rom of China brand Honor 6 Plus Pe-TL10.
This file can be accessed "Srktool backup" or in "dev/block/platform/hi-mci.0/by-name/" . Thank you.

Is there a way to do this for the PE-UL00?

Anyone tried it on PE-UL00 ?
Maybe there's a way to do the same.

Nice guide

Thanks juanro49 for the guide & the file.
The oeminfo works on PE-UL00 (tested myself- finally all google functions and no more strange chin. Stuff)

100 % working, I converted my Chinese PE-TL10 to EU one. Thanks for sharing it!

does anyone know how to convert to C636 ??

Hi guys,
self reply. I got through it. It was not completely without troubles, but finally I have Android 6.0 with EMUI 4.0.1 (build PE-TL10C432B571) in my PE-TL10 (originally on Android 4.4.2, EMUI 3.0, build PE-TL10V100R001CHNC00B260). I don't need a ROOT and custom recovery now so it is unrooted and stock recovery now.
First, I have never rooted Honor 6 PLUS and as it is not the newest device and it is not fully supported anymore by Honor MultiTool you have to use another way.
Bootloader has to be UNLOCKED - I used the MultiTool - it's fine and without any troubles
Device has to be ROOTED - that was a bit issue, because you have to flash custom recovery to be able to flash SuperSU and root the device. I did it via fastboot.
To enter the bootloader mode (fastboot) just switch off device, then hold Vol- and plug the USB cable - it should enter the bootloader mode - you should see the android robot and "phone UNLOCKED" indication.
Now you can use fastboot commands (you have to have proper drivers installed, you can find instructions on in another threads on XDA).
Or you can enter bootloader mode with command "adb reboot fastboot" - you have to be in the system (running Android) on the phone to run adb commands. It will restart your device and enter the bootloader mode after restarting.
Once you are in the bootloader mode with UNLOCKED bootloader you can flash custom recovery (necessary to flash SuperSU). I had to flash the proper custom recovery which I found here . I tried to flash another TWRP and CWM recoveries, but without success. You can flash the recovery with fastboot command "fastboot flash recovery CWM.img".
Then you can restart the device into the system with "fastboot reboot". Once you are in the system, you can reboot into recovery with command "adb reboot recovery".
In the recovery choose "install ZIP from ..." and choose this file. I had to choose the version BETA-SuperSU-v2.42.zip otherwise it didn't install anything despite the installation process was successful.
After the successful installation of SuperSU, you should have ROOTED device. You can check it for example with Root checker.
Then I mostly followed this tutorial. But with few modifcations.
I couldn't find this /dev/block/platform/hi_mci.0/by-name/oeminfo folder in my phone so I had to change the command for terminal emulator in the phone to dd if=/sdcard/oeminfo.img of=/dev/block/platform/ff1fe000.dwmmc0/by-name/oeminfo. There is another folder in "platform" folder but it doesn't contain "by-name" folder.
Then the tutorial says Press Vol-+ and Power to install the European update.app and we will have turned the PE-TL10 Chinese in European, but the issue is, you can't enter the "download mode" after you installed custom recovery. It simply doesn't enter the "download mode" and it stays on the screen with honor logo.
It was necessary to get into the system to be able to use fastboot command to flash stock recovery. How to solve it. I could't enter the system anymore, but I could enter the CWM. So I wiped the data and cache through CWM (Vol+ and Power button) and I was able to enter the Android system again.
I used again the "fastboot flash recovery B250.img" and flashed this recovery. It didn't correspond with my build version B260, but it helped.
Then I restarted the phone, entered again the system and through "Settings - Updater - Menu - Local update" and choose the "UPDATE.APP" from "dload" folder (it should be automatically detected) and whoila, it should restart the device and load "download mode" and install the UPDATE.APP. You should be able to do this step with Vol+- Power button combination instead of doing it through "Settings menu". And that's all.
I rather added some of used files into the attachment

Hello there I have a Honor 6 plus PE-UL00 that i want to change to European rom from China variant. Its rooted Android 6 Marshmallow with custom recovery TWRP
Firmware PE-UL00C00561. I'm still a beginning t limited knowledge,. I've learnt what I could from the forums. anyhow..
As per the changing rom guide , I downloaded The European rom B571 update.app and placed it in sdcard DLOAD folder as well put the OEM.img on the hard drive and ran termux and entered the command as per the guide and it seemed to work.
The Next step says ton turn the phone off And then press the volume+/- and Power button.. and it will load into the system and install the rom.
As per The post above, i got up to that step and the phone would Just boot to menu then reset.. I was able to get in recovery mode via TWRP and ran my backup.
I've read Post that the PE.UL00 can be converted, but is it following the exact same way as the PE-TL10? Or I may be missing a step.
The above post encountered a similar issue and had success, but his was a PETL10 and had hise his own recovery.img. (250.img to access his system and update the rom. in that scenario would l try to flash my recovery.img to get back into the system and run the local update?
Lastly another person had commented about their success converting a PE-UL00 to European rom. But just mentioned that it was through TWRP. Would that be just a matter of one I've done the OEM.img boot back into recovery and installed the app through TwRp or must I do a full wipe First?
Sorry for rehashing an old thread.. any advice much appreciated.
.

I got it working. After the OEM. IMG update I tried flashing it through TWRP. After some trial and error, my power button isn't responsive sometimes so maybe i wasnt pressing the volume down/up power button combo correctly. As the phone would just biot to Honor screen and reset.
Eventually after a few reboots and tries it went into the emui screen download mode and success.. I think. I did lose root in the process. I'm unsure how, still a novice, but I was able to re root the phone install custom recover via. TWRP and install SuperSU.
Now I don't have to deal with those China apps

PRA-LX1 I want to install stock firmware.

I want to flash my phone with stock firmware, but I cannot find it anywhere.
I am looking for PRA-LX1C738B123.
I own Huawei p8 lite 2017
I wiped my system because I wanted to install other rom, it didn't work so I want to go back to the original.
Unfortunately I wasn't smart enough to do a backup before so I am stuck atm. The bootloader is unlocked and flashing works, I can boot into huawei eRecovery and TWRP. (eRecovery gives the getting package info failed error) I have tried the dload method with other app files, it fails at 5% every time tho.
I tried using Huawei Update Extractor and Firmware Finder but I cannot find the exact firmware.
Could someone help me with installing my firmware? Oh and I am kinda new and it would be nice to get some guides,
Thanks.

I have the same problem but with a different firmware.. now only thing i can do is use dc-phoenix paid software (15$ for 72h of use). I will try that tomorrow as i also can't find exact same firmware it was on my phone.

Thanks for reply. I will take that into consideration, but from what I see you were looking for PRA-LX1C432B106 and they indeed have the c432 roms there, however they don't seem to have the ones that I have been looking for. They have a list of firmwares online. Anyway good luck.

Hello ! I think I could be of some help since I encountered the exact same problem !
edit: well I just realized I can't find your ROM with firmware finder either, sorry for the failed attempt
In your case I'd try with each firmware until one would work or a I tried them all.
You need some utilities first :
- Firmware Finder
https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146
It will allow you to find the stock ROM that fits your model
-Huawei UPDATE extractor
https://forum.xda-developers.com/showthread.php?t=2433454
It will allow you to extract the .img files from the firmware previously downloaded.
-fastboot and adb
https://forum.xda-developers.com/showthread.php?t=2317790
The programs that will allow you to flash the .img files.
Now:
1. Find your ROM using firmware finder (the model is usually on the box you received the android in).
2.Extract the necessary .img files : system.img, boot.img, recovery.img.
3.Reboot into the bootloader, connect your device to your computer, open a cmd exe (powershell in my case) by holding shift+right click on the folder containing the .img files and flash each .img file, e.g. for the system file:
"fastboot flash system system.img"
4.then use "fastboot reboot" and after that shutdown your device
(in my case even after flashing the .img files I was greeted by a blank screen, so I shutdown my device holding the power button).
5. Boot into recovery holding vol up + power buttons (be sure to disconnect your device before shutting down and powering it up again) and choose factory reset.
It should then reboot into ROM installation procedure where you will have to follow the same steps as when you booted your device for the first time.

Also, as far as my limited knowledge goes, there is no custom ROM officially supported for our dear device.

Yes I had the exact same problem, but once I did what I described, by rebooting into recovery (without twrp), I finally had the option to restore factory settings.
I believe the issue is in the fact you don't have access to the stock ROM for your model.

Where did you find the C432 firmware? I can't succees to find it

Flashing to a completely empty phone via DC phoenix or manual via fastboot still didnt got my device started. Sometimes I end up in the eRecovery and sometimes its just stuck at boot.
I tried different version from the hicloud but none so far did the trick. Maybe someone can point me into the right direction so i can finally rescue this phone?
EDIT:
PRA-LX1C432
Sorry cant link to these files since i don't got 10 posts. Maybe PM ?
Copied the Mega TWRP backup (B100) to SD card
Flashed TWRP via fastboot
Disconnected the USB cable
Boot into TWRP
Restored TWRP backup
Restarted phone into fastboot
OEM unlocked it
Got booted into TWRP since no stock recovery there
Booted into fastboot again
flashed stock recovery
Android started to work!
Tried to update to B164 and failed
Reboot
Now it offered B110 and I tried to update to B110. Success.

[TIPS] Revert Custom Rom to Official and untouched - Hard restore

Hi!
I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.
After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.
1. You ave access on TWRP?
-If not, pleas unlock your bootloader (again) and flash TWRP recovery for you actual version (marshmallow or nougat).
-perform a full wipe and restore your partitions on "ext4" format, shutdown phone.
2. Get a "oem_info.zip" for your model phone (dont extract the .zip) and push it on your internal or external sd.
-This archive contain cust and oem info for patched your phone at the correct manufacture information.
-I have a link for VNS-L31 (c432, but is not very important) HERE LINK
-If you have other model (VNS-L31) pleas find a correct patch for you (VNS-L21, ...).
3. Find and download a EMUI marshmallow official full-ota update.
-for a VNS-L31 i advice choice a VNS-L31C432B160 full-ota update.
4. Unpack your update archive.
5. Create "dload" folder on your internal or external sd and put it UPDATE.APP
6. Reboot phone on TWRP recovery and flash "oem_info.zip"
7. Use dload methode for update (hold 3 buttons phone and dont release before "dload screen" appears)
8. Unlock your bootloader again (important!) And make a factory reset
9. Your phone reboot (please wait ) and done!
Ok now you are on official version, please update on setting menu >> update and choice, rest on official or flash a custom rom..
P9 lite brick precision:
In my personal experience the "p9 lite" is very easy to flash, mod or other tips and the risk of HARD brick is very very tiny.
If you see this page and your phone bootloop, relax, keep calm at 99,999% you have a little and ridiculous brick
Good luck and flash happy!

Hi!
I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.
After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.
1. You ave access on TWRP?
-If not, pleas unlock your bootloader (again) and flash TWRP recovery for you actual version (marshmallow or nougat).
-perform a full wipe and restore your partitions on "ext4" format, shutdown phone.
2. Get a "oem_info.zip" for your model phone (dont extract the .zip) and push it on your internal or external sd.
-This archive contain cust and oem info for patched your phone at the correct manufacture information.
-I have a link for VNS-L31 (c432, but is not very important) HERE LINK
-If you have other model (VNS-L31) pleas find a correct patch for you (VNS-L21, ...).
3. Find and download a EMUI marshmallow official full-ota update.
-for a VNS-L31 i advice choice a VNS-L31C432B160 full-ota update.
4. Unpack your update archive.
5. Create "dload" folder on your internal or external sd and put it UPDATE.APP
6. Reboot phone on TWRP recovery and flash "oem_info.zip"

I can do everything up to point 6... won't enter to twrp... stays on Your device is now booting...
Update: I can now reach point 7 but now won't do dload (3 buttons) method... Huawei logo all the time. Can't even turn off the phone

In my other thread you post the same problem but is not entirely the same..
You succeeded to enter on fastboot mode? Flash recovery?
If you follow the steps 1-5 is impossible to fail the 6 point..
You have acces on fastboot mode or not?..

I did update the post... 3 hours ago I wasn't able to enter TWRP, some way I did managed, now I can enter fastboot, I did flash custOEM (sorry I don't remember exactly the name but it's the one of your post) .zip file. Now I can't do dload method, stuck on huawei logo. If I try to go to recovery, I got red message "phone fail validation"...
I know, I post on both but I was trying to do everything...
just tried... validation red error message won't let me go to TWRP now...

You have a VNS-L31C432?
Your phone does not enter at dload mode?
Wipe all partitions an retry flash a oeminfo for your model phone (if not C432 you need right oeminfo).

How can I wipe all partitions if stuck in Huawei logo? Is there a way to do everything from adb command line? (I'm using Mac and cannot use all the tools I've found here XDA neither hiSuite which is basically a backup photo/video only the Mac version).
Thank for helping, really appreciate
To answer your question in the other thread, yes bootloader is unlocked and I am on C432.

What's your rom have before the bootloop?
You have the right version of TWRP for your rom?
If you have a MM version Don't flash a TWRP for N.
Send me a link to TWRP version used (thread forum)

Before the bootloop I was on L31C900 (on the phone) but I did actually flashed C432B160 because I did rollback. TWRP used I've found in the other post where there's a OEMfile to flash (but for this I need to double check because I did look so many pages which I am not 100% sure.

I not have experience on other model that C435.
But i suggest to find a oeminfo for your variant (C900?)
For TWRP you need flash a version for MarshMallow HERE
Flash it and pas return here (fastboot flash return and first enter to new recovery)

Hi, found Windows emulator for MacOs so I extract from update.app boot.img and flash.
I did format all partitions as told using a proper twrp this time.
What's next step, system says NO OS INSTALLED?

Flash partitions on .img files is not needed.
Just find a corect oeminfo for your model phone.
Flash it on TWRP recovery.
Use dload methode to update on basical version (MarshMallow b160).
After that, unlock bootloader again and make a factory reset.
Switch on your phone (the first boot make long time).
Update on last emui on OTA.
Done!
After that you able to install a custom rom.

Thanks again you're saving my life!
IT won't turn off so been always on it won't keep the charge... Writing so because apparently it won't go to download mode (dload) if plugged in. On the other way if I unplugged from power it won't even start. Shall I force to download mode using console ADB or FASTBOOT? I had looked but can't find anything...

Correct. Because I'm not able to switch it off it won't keep the charge. When discharged, the minute I do plug on charge it wakes up... That's the loop...
My main question is: does a command exist to enter download mode using terminal?

You have a hardware bug?
No abd command to enter dload mode..
Try flash a update.zip with twrp (not guaranted)
After that unlock bootloader again and make factory reset.

Hi, I followed this guide to go back to stock from elite rom. I flashed my oeminfo.img on twrp and then went to dload combination. Do I have to unlock the bootloader after the reboot? Thanks!

Hi,
I followed your guide and it works perfectly thanks!

(Help) My P8 Lite 2017 (PRA-LX1) is bricked

Hello,
I was trying to install a custom ROM from TWRP to my P8 Lite 2017 and I wiped all partitions except MicroSD.
The installation failed and I got the stock ROM and then I discovered that my bootloader is locked. I can access TWRP and when I flashed the stock ROM the phone just boots to TWRP Recovery. And I can't even unlock the bootloader because the phone doesn‘t have any OS and I can‘t enable OEM unlocking from the system settings. And because I have TWRP, I can’t access Huawei Recovery. So my phone is basically bricked.
Any help will be appreciated

Use dload with a service firmware.
You need to flash this 2 times,once for the firmware and second time for vendor,and the firmware UPDATE.APP can be found in the update_sd.zip and the vendor UPDATE.APP can be found in the PRA-L31 or PRA-L11 folders (most likely you will have PRA-L31,you can find this in the engineering menu by going into the dialer and typing this: *#*#2846579#*#*,and then going to Veneer Informations and Version Info,but since you cannot boot flash PRA-L31 vendor).
http://androidhost.ru/6uc - this is latest firmware,but takes a very very long time to download
https://mega.nz/#F!nwhAWDjC!cNovAN6dKLlO_YZ9fjMbzQ - this is the first official firmware released,but download speed is very good
If you don't know how to use dload you can look it up on forums.

If your phone is really hard bricked and can't do anything, check this out:

Dload works no matter what,at least I was able to enter it when I bricked my phone,even when I completely screwed up my recovery partition,so you should be good. Try using it with the service firmware I left you.

Now I have downloaded the service firmware so how I am going to flash it now? Like do I extract the UPDATE.APP and flash it in TWRP or what? You said that flash UPDATE.APP, but am I going to do that in dload mode or TWRP?

In dload,make sure you make a folder in the root of your sdcard called dload and put that in there.

Hm,make sure you used the service firmware I left you,but if you are sure you did,your last resort is DC Phoenix which you will need to pay 20 euros.

if you have TWRP installed could you make a backup of your oeminfo partition so we could provide you the right firmware to recover your device

I've tried a different firmware for my device and now I can't get to dload anymore so does it mean that I've chosen the wrong firmware? And by the way I read somewhere that if the dload says error it can depend on the microsd card.

I tried it again with the service firmware and I got to dload and it didn't have error anymore and now I've got everything worked and my phone is unbricked

I was stuck with a similar problem. Device bricked and flashing TWRP and restoring backups, then stock recovery and stock roms, but nothing worked until I found this post. Thanks a lot dinoderda for your help.

Hello again, I've been using the older service firmware for few months now and now I decided to install the latest service firmware after I had no success with flashing the firmware through TWRP and I downloaded the service firmware put the necessary files to the dload folder and installed it via the software update in the dialer and typing *#*#2846579#*#* and going to dload that way. It installed to 100% and then when it restarted it goes to Error Mode and it says to update the firmware again but it just loops to error mode and I cannot do anything so I think I accidentally removed some neccessary files in the dload folder but now I would need to fix the error mode loop.
