A couple of days ago my Huawei p7 started to shut itself down and after that it keeps rebooting.
It starts itself up and I get into the choose your language screen and then it shuts down.
When i try to get into the system recovery (using volume & power) I get the following screen:
Android system recovery <3e>
Huawei software installed failed.
Please retry!
Shutdown system now
There is no UPDATE.APP
.............................................
FAIL
And even in system recovery it keeps rebooting.
Im kinda helpless at the moment not knowing what to do.
Did this occur to anyone ? Is there a solution for this problem ?
Thanks in advance.
You should download firmware update file from Huawei Official web site. Extract dload folder from downloaded archive and put it on your SD card. After that you should try to trigger firmware update with factory reset (method which is usually called "force update") by holding all three buttons when the phone is turned off.
But maybe your phone have some hardware problem if it restarts even in recovery mode.
UPDATE:
Does phone restarts itself when it's in fastboot mode (you can get into that mode by holding VOLUME DOWN and POWER button while phone is turned off and connected into USB port of computer just before pressing that button combination) ??

I've downloaded the update file and proceeded with your steps. I continued to trigger the firmware update with the factory reset.
At first it seemed to work, the phone started updating but after a couple of seconds it started to reboot itself again
I got the phone in fastboot mode and at this moment it does not restart itself !
I went on downloading Hisuite and at this moment it keeps searching for drivers on the network.
The searching for drivers is taking quite some time is this normal ?
Thank you very much for your help so far !
OK, maybe these are good news if you say that your phone doesn't restart when it's in fastboot mode.
I would recommend you to try to reflash your phone's stock recovery and boot images with those extracted from firmware that you are trying to install.
Follow these steps:
Download Huawei Extractor tool from here,
Open update.app with Huawei Extractor and extract next two images: RECOVERY and BOOT (you can do that by selecting those two images while holding CTRL button, then right click > Extract Selected),
When extracted, rename those two images into "recovery.img" and "boot.img",
Copy those two images into "platform-tools" folder of Android SDK,
Run command prompt and go to "platform-tools" folder by using "cd" command,
Start your phone into fastboot mode,
Enter following command into command prompt: "fastboot devices" (without quotes), you should get your phone's serial number listed, if that's right, go to the next step,
Enter: "fastboot oem get-bootinfo", it needs to say that your bootloader is unlocked. If it's not you need to enter the next command "fastboot oem unlock 1234567812345678", where "1234567812345678" should be replaced with unlock code that is unique for your device. Instructions which explain how to obtain unlock code for your device can be found here,
Flash your phone's recovery with "fastboot flash recovery recovery.img",
Flash your phone's boot image with: "fastboot flash boot boot.img",
After successful flashing of both images, turn your phone off by holding POWER button for a several seconds,
Prepare SD card on your PC by formatting SD card and copying "dload" folder of phone's firmware onto SD card,
After you insert SD card into phone, start your phone with "forced install" method by holding all three buttons on your phone.
After that your phone should process firmware install successfully if there is no some hardware issues. Good luck and inform us about your progress.

Enter: "fastboot oem get-bootinfo", it needs to say that your bootloader is unlocked, if it's not read this,
Flash your phone's recovery with "fastboot flash recovery recovery.img",
Flash your phone's boot image with: "fastboot flash boot boot.img",
After successful flashing of both images, turn your phone off by holding POWER button for a several seconds,

Hi,
I've got the same issue.
When I start to "force install" method, my phone doesn't boot.
It just stay in a state of "charging" but nothing append.
I flashed boot and recovery with Fastboot.
But now, when I start the phone in Fastboot&Rescue Mode, the device doesn't appear in the liste when I run adb devices.
But when I start in the "force install" mode, adb devices returns the serial of the phone (but it doesn't respond to fastboot command).
Are there other files to flash on the phone than juste recovery and boot ?
Thank's for those steps, i'll continue to try to flash again.
Edit :
Ok phone is back !
The problem came from my SD Card, I had not only the dload folder, but an other file.
Format SD Card -> dload folder -> "force install" method -> ENJOY !
Thank's a lot !

I followed all your steps but i get stuck at step 7. When I give the command fastboot devices it doesn't show my phone's serial number. Instead it shows a ? (question mark).
Did I do something wrong or is there a solution for this?
Thanks in advance!
Maybe you should try other version of platform tools. I would recommend you to download adt-bundle-windows-x86_64-20140702.zip (x64) or adt-bundle-windows-x86-20140702.zip (x32) from "Android SDK" official web pages (I assume that your are using Windows OS). After download extract only "platform-tools" directory to the root of Windows C:\ partition and try described procedure again.
However if you are still getting question marks instead of phone's serial number, you should ignore that step and go onto the next one. I had the same problem in the past and flash commands were successful even serial number wasn't been displayed.
Keep us informed about your progress. Good luck zbnd !!

Thanks for your response !
So I followed through like you said. Gave the fastboot oem get-bootinfo command and then I got (bootloader) locked. So I followed the bootloader's unlock code (official way), entered my product SN and product IMEI, used the Huawei Product ID generator followed the procedure and all I get is : Please input the correct Product ID
What did I do wrong this time ? I'm not sure if it's even possible to do this wrong. Is there another way around ?
You can unlock with Vroot, like I did. I didn't try to get a serial from Huawei.
For the Fastboot command 'Fastboot device's I had a ? too, but with 'adb devices' command, I got my serial number.

I've downloaded Vroot (english version) but when i connect my phone it says not support mode
I tried to connect while in fastboot&rescue mode, because this is the only way the phone stays on without restarting.
I then tried to connect without fastboot&rescue mode. But my phone keeps rebooting. I did get a message that USB debugging is disabled. However I can't enable usb debugging because my phone won't boot up normally.
@Pboguet
You should read carefully because your answer has no sense for the phone which is in state like zbnd's phone is.
@zbnd
Maybe you are doing something wrong. You can send me your's phone serial number and IMEI in PM inbox, I will try to generate unlock code for you.

Despite following all your steps my phone keeps rebooting
Sorry to hear that. Did you manage to make all steps that I described to you? Can you share more informations about your current efforts please.

After unlocking my phone I got the message unlocked in CMD.
I then flashed recovery and boot. Both times it said that the flash was succesfull, this only took a few seconds I don't know if thats normal? I then followed your last steps ( dload folder etc) and put the SD card in my phone.
It start installing but after approximetaly 25 seconds the phone shuts itself down and then reboots.
The procedure then starts again and it starts installing followed by shutting down and rebooting.
I'm sorry to hear that. Seems like it's some hardware issue.
However I still have one more idea that you can try in fastboot mode. I would recommend you to install entire firmware manually with fastboot commands.
By following previously described procedure try to extract with "Huawei Extractor" tool next images also: SYSTEM, USERDATA, CUST and CACHE.
After step number 10, try to use next commands also:
"fastboot flash system system.img"
"fastboot flash cust cust.img"
"fastboot flash userdata userdata.img"
"fastboot flash cache cache.img"
When you are finished with flashing of all images, use "fastboot reboot" command to restart your phone. Steps 11, 12 and 13 should be ignored this time.
Let me know the result
Hey, I'm glad I found this forum, because I have exactly the same problem! Since zbnd did not reply I wanted to let you know that flashing boot.img, recovery.img, cache.img, userdata.img, cust.img and system.img via fastboot did not work
The commandline for each file said "OKAY" and "finished" therefore I assume the process(es) completed succesfully.
Maybe I should tell you some information and the steps I did with my P7:
- my device is a branded german telekom version with firmware P7-L10-V100R001C150B122- because of crappy pink telekom bootlogo und bloatware I wanted to flash the original huawei firmware so I downloaded the B126 from the official website and updated via force update method- at the end of the update process i got the messages "huawei cust fail" and "update_post_process fail" but when I rebootet the B126 was installed and showed a message "Defect report reminders - This is an internal test version. Please report defects to Yangyexiao 00143718" - can't be correct, I thought- after googling a lot and reading through several forums I rooted my device with RootGenius, installed HiSuite and Android-SDK (driver were installed correctly, adb devices showed a device with serial) and deleted the "cust" directory on my phone - at that point everything still worked- next step: I installed TWRP 2.7.1.0, made an updateable zip file with huawei update extractor (including system.img, userdata.img, cust.img and boot.img) and flashed it via TWRP. The process completed succesfully, but needed only a few seconds. After that I got this bootloop at the language selection- then I wanted to return to the last functioning state, so I flashed the stock recovery via fastboot and started with force update method. But after a few seconds the device rebooted during the update process which led to another (maybe the same) bootloop. I had to remove the sd card, but the device continued to reboot in recovery mode. So i installed TWRP 2.7.1.0 again- Then I tried to restore a B133 backup I got from another forum, but it obviously did not work (see attached image)
Now I just don't know what to do ... I get a bootloop in stock recovery and I get a bootloop in TWRP 2.8.0.0.
Only TWRP 2.7.1.0 does not reboot. What is about the other files inside the UPDATE.APP (modemimage.img, efi.img, etc)? Is it possible that some of these files are needed?
Thanks in advance...

If this recovery works than try:
1. Save this Se7en or this HRT or this custom MIUI ROM on SD card
2 .Wipe in TWRP everything (dalvik, system,data,cust, internal) except external (SD card). Internal only if You have a backup or not important data there.
4. Install zipp ROM from external memory. Sometimes try more than one time in fail case. For HRT ROM especially.
Let me know if helped.

I tried se7en and miui.
I wiped dalvik,system,data,internal,cache and custom, which only lasted about 2 seconds, but said succesful (Is that enough to delete all partitions?).
Installation of both custom roms completed succesfully and lastet several seconds (max 1 min I think).
Se7en: reboot -> huawei logo -> reboot -> language selection (in the style of stock rom?) -> reboot ...
Miui: reboot -> miui logo -> reboot -> language selection (miui style) -> reboot -> wifi selection (I skipped) -> searching for sim card -> reboot

To use fastboot you need to unlock bootloader first. And before flash, you need to erase partition first, for a proper job. Please read well about the fastboot procedure is a dangerous procedure
My bootloader is unlocked, but fastboot sais I don't have permission to erase partitions ...

I have discovered multiple ways of downgrading ZenFone 2 Laser out of which two methods proved out to be easy and reliable. Both methods have been tested and are working.
Method 2 doesn't require root while method 1 needs root access.
Pre-requisite: Stock firmware zip file. You can find download links from index thread for all variants.
WHILE THIS GUIDE HAS VERY LESS CHANCES OF MESSING UP YOUR DEVICE, HUMAN ERROR CAN ANYWAY HARM THE DEVICE. I AM NOT RESPONSIBLE FOR ANYTHING YOU DO TO ANY DEVICE. YOU ARE DOING THIS AT YOUR OWN RISK
METHOD 1: Requires ROOT-
Short instruction:
Some users say you can downgrade by renaming the OTA zip to correspond to a higher version but that will NEVER work because the update script has this line
(!less_than_int(1457089250, getprop("ro.build.date.utc"))) || abort("Can't install this package (Fri Mar 4 19:00:50 CST 2016) over newer build (" + getprop("ro.build.date") + ").");
Click to expand...
Click to collapse
The recovery reads ro.buid.date.utc value from buid.prop. If the value is less than the value in updater-script (like the value highligted in above quote) any recovery will not flash it, neither stock nor custom. Just increaase the value of ro.build.date.utc (in build.prop) to any value higher than the value in updater-script and then flash the zip via recovery.
Detailed Instructions:
1. Open updater-script from the firmware zip. It will be found in /META-INF/com/google/android inside the .zip
2. look at the first line (!less_than_int(1457089250, getprop("ro.bui....
3. The value 1457089250 is taken as an example, your updater-script may have a different value. Keep a note of this value.
4. Install any root file manager like ES file explorer (if you dont have already)
5. Goto /system (the system folder) using the root file manager. Grant root access if prompted
6. Open buid.prop file as text and look for the line "ro.build.date.utc=1446585430"
1446585430 is taken as example, your phone will have a different value.
7. Now increase this value in build.prop to any number greater than the value you noted from updater-script
for example, if my updater-script has 1457089250 this value and buil.prop has 1446585430 this value, I will simply change the value in build.prop to 1546585430 or 1448585430 or 1457089251. Any number greater than 1457089250 will work in my case.
8. Now reboot to recovery (vol down + power)
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.
Method 2: Without root, requires computer
Short instructions:
As I mentioned earlier, recovery reads "ro.build.date.utc" But you can bypass this check by erasing system partition.
Just do
Code:
fastboot erase system
from fastboot mode and then flash the zip from recovery
Detailed Instructions:
1. Install Asus drivers to your computer. (link in index thread)
2. Download adb_fastboot.zip and extract its contents
3. Reboot your phone to 'bootloader mode'. To do this turn of your phone completely. Hold "volume down Up" button and then press and hold power button. Release power button after Asus logo appears and then release volume down button. Your phone is now in bootloader mode.
4. Connect your phone to pc via a reliable usb cable. Look at your phone screen. It should display "Fastboot mode!"
5. Now go to the folder where you have extracted all the files. Holding down shift key, Right click on any point on white screen. Then click on 'open command window here' from the menu that appears. Command Prompt will open now
6. On command prompt type
Code:
fastboot devices
and hit enter
and check if it is detecting your device.
7. Then type
Code:
fastboot erase system
(this will erase your current OS, you are warned!)
8. After it is done type
Code:
fastboot oem reboot-recovery
to boot into recovery mode
9. Select "apply update from external sd card" select your firmware zip file, and then select yes to flash. It will take 5-10 min
10. (optional but recommended) Wipe factory/data . If you don't do this, you will see the annoying "Android is upgrading.." screen which takes around 30-40 mins to reach home screen.
Successfully downgraded to 1.16.40.763 from 1.17.40.1234 without root

Failed to mount/asdf.
So i like to flash the lolipop recovery while iam on the marshmallow and then do apply update from sd card. I like to go back to the 1.13 lolipop firmware
Is it possible to to flash the lolipop recovery while iam on marshmallow. If possible. Help me how to do that

"Failed to mount /asdf" error is harmless you will get that error even on latest twrp. You can ignore the error and use the MM stock recovery like normal. Recovery will do its job it can format, install updates, clear cache and everything, you just need to ignore that /asdf error
But you can use any stock recovery from any firmware version lower than or equal to your current firmware version. Drawbacks: You cannot apply update to MM OTAs if your recovery version doesn't match the current firmware version.
Going back to stock 1.13 is a bad idea. I would recommend you to stay on MM since it has many performance improvements.
But still if you want to go back to lollipop, consider downgrading to the last lollipop update i.e. v1.17.40.1531

"Failed to mount /asdf" error is harmless you will get that error even on latest twrp. You can ignore the error and use the MM stock recovery like normal. Recovery will do its job it can format, install updates, clear cache and everything, you just need to ignore that /asdf error
But you can use any stock recovery from any firmware version lower than or equal to your current firmware version. Drawbacks: You cannot apply update to MM OTAs if your recovery version doesn't match the current firmware version.

I got a 412 mb ota update some days before. I downloaded it. Apply it for proceed. Then it start checking system as usual phone restarted. But update did not happened. Instead this same error show up. Then i can only reboot system. Got an update failed message.since that when i check for updates iam not even getting any. May be it will be solved by a factory reset .but even if i get an ota. The update wont proceed .because the recovery wont allow me to do that
And also that wipe cache partition also results the same error .so without solving this error i cant update to the latest MM too :/ .
In my experience, the most reliable method is to
extract the recovery from the version of stock ROM you want to upgrade or downgrade to
Flash that recovery with fastboot
Wipe /system in fastboot
Reboot to recovery and update with the stock ROM .zip
Or
Even easier, use Sziraqui's fastboot ready .IMG files and just flash them via fastboot.:good:

The recovery is included in the stock ROM zip file. Extract the zip and you will find it inside.
Presumably if you want to flash the stock ROM you have already downloaded it?

I found out that recovery for each firmware is available here. You should use a desktop browser to use this website.

Thank you.
Can ZE551KL use the recovery.img from ZE550KL? My ZE551KL has the extra 1700(AWS) band.
Please where are you guys downloading your stock rom from?
The stock zip is NOT flash-able like a custom ROM .zip. That's not how it works. If the Roms you have are custom recovery flash-able, they are not the OEM rom, they have been modified.
All the Roms I have come with a recovery.img file...
Then again if I have to explain how to use fast boot to flash the recovery, there is a good chance you shouldn't be messing around with fast boot.......

You don't need to unlock bootloader for flashing stock recovery that you downloaded from the above mega drive.
To flash the recovery.img (or any .img) You need to have Adb and fastboot files in your pc as well as Asus Zenfone drivers installed
All info and downloads for adb and fastboot can be found here
Search and download Asus ZenFone 2 laser drivers.
Once you have your pc setup with these tools,
With Administrator priveleges, locate the folder where adb.exe and fastboot.exe files are present. Hold down shift key and right click on that folder and select "open command window here". Then reboot your phone to fastboot mode [power off, hold vol up +power, release power when logo appears]
Connect your device to pc.
Type the following command on cmd
Code:
fastboot devices
Output should be something like this
Code:
FCAHSJSJJAKAK fastboot
This command will check if your device is connected or not
If output is blank, device is not being detected.
To flash recovery.img, copy the recovery.img file to the same folder where fastboot.exe exists and then type
Code:
fastboot flash recovery recovery.img
Output is easy to understand, if it says [OKAY] then flashing succeeded
Tried downgrading ze551kl by fastboot erase system then installing .zip from Asus website (via sdcard). All of the Asus updates except the earliest fail with 'fota return code 403'.
1.14.40.550 installs ok but then boots (gets as far as displaying the wallpaper), gives an error message in german (looks like 'android media process stopped') and goes into boot loop. Anyone seen this before?
Also, any way to build a recovery.img from the Asus update files?
invalid boot image whenever i flashed stock recovery,any one know why ?
What i do is flash the stock recovery and flash relock bootloader.

I think OP needs a small correction to enter into FASTBOOT you need to press volume up and power instead of volume down and power buttons

Hey guys,
Need some help here as I've checked everywhere I possibly can and can't find the answer. I've rooted phone then installed miui 6 rom which worked but i didnt like it. Then I tried to install my rom 3.3 and everything got fuked up. Now when i power on my phone it is in bootloop. At this moment i am only able to use twrp 2.7.1.0(only recovery that is working) and fastboot. I've tried wiping data through recovery and still nothing. Anyways my bootloader isunlocked. .
Also I've tried the forced update method to get it working again but for some reason I cant start it, just a bootloop.
When i try to install custom rom it just give me message "unable to mount data". Same message i get when i try to do factory reset or wipe data.
Appreciate the help guys.

The force update will not work since you replaced the stock recovery from Huawei with TWRP.
Follow these steps:
1. Go to Huawei's website and download the UPDATE.APP package.
2. Go to Huawei's website and download the Update Extractor tool.
3. Use the downloaded tool to extract the UPDATE.APP package. Then you should have a folder filled with .img files such as system.img, recovery.img etc.
4. Connect your device to your PC and enter fastboot on your Ascend P7 device
5. Open up Command Prompt or Terminal (cmd for Windows, terminal for Linux) and go to the directory where fastboot is installed
6. Check to see if your PC finds your device using the command: "fastboot devices". If successful, you should find your phone listed.
7. Flash this partition images using these commands:
"fastboot flash boot /path/to/your/images/boot.img"
"fastboot flash system /path/to/your/images/system.img"
"fastboot flash cache /path/to/your/images/cache.img"
"fastboot flash cust /path/to/your/images/cust.img"
"fastboot flash userdata /path/to/your/images/userdata.img"
5. Reboot your device
Now if successful, your phone should have EMUI installed on it. Hope this helps you.

I tried that long ago, but it said it cant write to data or smth like that.
So I have a p10, and decided to see what i could do with it. Having little experience, I managed to get somewhere. Unlocked the bootloader, got twrp, installed it with the command fastboot flash recovery recovery.img and got:
target reported max download size of 471859200 bytes
sending 'recovery' (32034 KB)...
OKAY [ 1.012s]
writing 'recovery'...
OKAY [ 0.200s]
finished. total time: 1.222s
WOOT! Awesome! No problems! Then I issued: fastboot boot recovery.img
And got
downloading 'boot.img'...
OKAY [ 1.020s]
booting...
FAILED (remote: Command not allowed)
finished. total time: 1.030s
WTF?!
So after a bit, I misread and flashed boot.img with: fastboot flash boot boot.img
I guess I flashed the wrong image. I dunno. But now it boots into the screen that tells me "Your device is unlocked and can'r be trusted" tells me its booting, reboots, goes to the same screen again, says its rebooting again, then brings me to Huawei eRecovery. I connect to my wifi network, telling it to download the latest version and recover, and it says "getting package info failed" So I ma stuck with a device that won't boot.
Oh yes, and down volume and power don't bring me to fastboot anymore.
Begging for help here please.
Do the whole rebranding to unbrick, not sure if you flashed wrong image on boot.
Advice: When flashing recovery boot it by powering off and using key combo. Or adb command. Not from fastboot as IMG.
I did a google search on rebranding to unbrick, and found a guide on the 9. So I assume its similar. It first tests me to boot into twrp. I can't. Twrp never got installed. The next step is to get the offical firmware and put it on the SD card. I can't find it. I am in Canada, and can't find any firmware for canada, nevermind anything north american. It is however possible I have found the wrong guide, as I don't really know what I am doing. As a complete noob, links to guides would be nice when possible and available when making recommendations.
The guide is the same for Mate 9/pro and P10/plus
Original: https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
Explained as easy as posible:
Unlock bootloader (check again that boot loader is unlocked)
Download Update ZIP. I suggest rebrand to VTR-L29 C432 !
A. Get ROM update link through hwmt.ru. Click "filelist.xml". ---> http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=VTR-L29&firmware_page=0
B. Observe "update.zip" size, choose more than 1GB file size FULL OTA . Example VTR-L29C432B164 filelist Link, all three update files and path are in the filelist.xml content.
update.zip: Change URL last "filelist.xml" to "update.zip" download file.
update_data_public.zip: Change URL last "filelist.xml" to "public/update_data_full_public.zip" download file, and rename it to "update_data_public.zip"
update_all_hw.zip: Change URL last "filelist.xml" to "hw/spcseas/update_full_hw_spcseas.zip" download file, and rename it to "update_all_hw.zip" Where spcseas is the model of the file you are downoloading.
Update Package (Download these at original post)
Base: HWOTA_2017050101_Base.zip
OS: Windows -> HWOTA_2017050101_Windows.zip
Model: P10 -> HWOTA_2017050201_VTR.zip [Thanks to @crucky verify]
Put HWOTA on pc desktop and on your external SD card (if you have one, otherwise update process will took a couple of minutes more)
Those 3 downloaded files goes on UPDATE dir, inside HWOTA
Run batch file "update.bat" for same model update or rebrand with/without sdcard.
Select rebrand chose what model is desired (Must be the same as the update package)
Always check the process continues (Sometimes it stucks on twrp or need reconnect to PC)
Once finished Factory default reset will start
Do the process twice! select "Same model update" on the second time.
After update successfully, device might be locked again.

okay, i know you are trying to be helpful, but I just can't follow it...
You said "Download Update ZIP. I suggest rebrand to VTR-L29 C432 !" Which one of them? Is the B just a build number, and I should get the latest? please remember, you are talking to a noob.
You talk about 3 files, update.zip, update_data_public.zip and update_all_hw.zip Do I need them all? If so the last one, where I change filelist.xml to all /cn/update_full_all_cn.zip doesn't work. See the following link http://update.hicloud.com:8180/TDS/.../v92067/f2/full/all/cn/update_full_all_cn.zip
Also, rename the file, "Where spcseas is the model of the file you are downoloading" Huh? I know I have to replace the word spcseas with something, but with that?
Now it says to run update.bat Whats the point? I have not been directed to plug the phone into the computer, and even if I did, the computer won't recognize it because I can't get it into any mode... Where do I put these files? They all go in the same directory? I just can't follow this guide as much as I try..
THERE IS GOOD NEWS HOWEVER!
I have been able to get it into TWRP! This means I can get into fastboot, which means I can re-flash the correct boot.img, IF I can get my hands on it (and assuming that's the actual issue It likely is. It was working until I flashed this other boot.img file.). So if I can get direction on how to get it, I should be okay. Double triple and quadruple bonus points for just providing me a direct link to the boot.img file to use without having to play around trying to follow guides I can't seem to understand.
UPDATE!!
Now although I can get into TWRP, its hit and miss, but I can get there eventually, it will no longer boot into fastboot/recovery. When I click reboot, and choose bootloader in TWRP, it just freezes..
This is getting frustrating. Apparently getting into the bootloader is hit and miss, but i can do it.
Search for Huawei update extractor in order to get BOOT.IMG from update.app (inside update zip) I could upload one myself, but I'm not at home right now.
TWRP doesn't support reboot atm. You must power off completly. To boot to recovery press power on and vol + until huawei logo appears, then relase power. It should boot to recovery TWRP in this case.
For boot bootloader you press vol - when you are connecting usb cable to PC.

Thats good to know. I was getting TWRP more often when I did it from off. What was happening was I would holds power and volume up, release power when the logo appeared, and MOST of the time I would boot into TWRP. Sometimes it would just reboot, I would continue to hold up, and it would either reboot, or boot into TWRP. Occasionally I would get the recovery that came with the phone ?!?!
In any event, I managed to get into TWRP, boot into recovery, extract the boot.img, flash it... AND IT WORKED! Phone booted!
So after all this, I backed up EVERYTHING I could using TWRP. The Boot partition, System partition, EVERYTHING! It kept failing on the Data partition, but from my research that wasn't that important anyway. I then installed SuperRoot_noverity_nocrypt.zip, rebooted, installed phh's SuperUser, installed Root Checker, and finally, I have root!!
Thank you so much for the help. About to go "thank clicking" for all the help you provided.
Warning - USE THIS GUIDE AT YOUR OWN RISK. I AM NOT RESPONSIBLE IF YOU END UP BRICKING YOUR DEVICE.
[Update 29.08.2019] Added new download locations for raw images
[Update 07.01.2019] Added more current raw image for ZS620KL WW 80.30.96.111
[Update 25.10.2018] Added raw image for ZS621KL.
[Update 09.08.2018] Updated for 80.11.37.95 and future versions.
[Update 20.07.2018] I was able to root FW 80.11.37.86 with Magisk Manager 5.8.3 so you are no longer locked to FW 80.11.37.69 and do not have to downgrade.
This guide is split into two sections: rooting and downgrade/unbrick.
Each section is split into a quick how to for experienced users and a more detailed guide.
General info:
The most current firmware as of 20.07.18 is 80.11.37.86. Newer versions will work too!
This guide is written for firmware 80.11.37.86. If you do not want to upgrade/downgrade to 80.11.37.86 you will need to use the firmware (zip file from ASUS) you are on in all the steps.
If you upgrade your firmware to a newer version AFTER rooting it you will lose root! You will need to patch the boot.img of the new firmware again > follow the rooting guide.
I have only tested this on my ZS620KL Z01RD WW version. It should work on other variants JP/RU.
Magisk hide is working and Safetynet check passes.
Bugs/problems:
Unlocking the bootloader will void your warranty! Currently there is no method known to relock it!
You will get a warning message about your unlocked bootloader at every boot.
You will no longer receive OTA updates but you can download the new firmwares directly from Asus.
You will get a warning message about an internal problem every boot. Which you can disable if you do not need write access to the vendor partition.
> see rooting guide 10.

[Rooting how to]
Upgrade to firmware 80.11.37.86 and enable usb debugging.
Unlock your bootloader with the app.
Extract boot.img from firmware using payload_dumper.
Patch boot.img with magisk manager.
fastboot flash boot patched_boot.img.
Enjoy root.
[Rooting guide]
You can root any firmware from 80.11.37.86 up with this guide. To upgrade to a newer firmware version copy the zip file (e.g. UL-Z01R-WW-80.11.37.86-user.zip) you downloaded from Asus
to the root of your phones internal memory and reboot or unplug your usb cable.
You will get an update found notification. Start the update. To downgrade check the downgrade guide below.
Enable usb debugging in System > Developer options. If you can not see System > Developer options go to System > About phone > Software information > Build number and tap it multiple times.
This will make the Developer options visible.
WARNING! Upgrading to some firmwares disables usb debugging and you need to enable it again.
Make a backup of all the data you do not want to lose.
Download the platform tools and extract them into a folder (i will use c:\5z\ in this guide) this will create a subfolder platform-tools.
You need a current fastboot version for this to work (due to a/b slots/partitions), so please use the current platformtools!
Download the bootloader unlock app, extract the UnlockTool_9.1.0.3_180621_fulldpi_Draco_GDPR.apk and copy it to your phone.
Use a filemanager on your phone to install it and follow the on screen instructions to unlock the bootloader.
WARNING! You will lose your warranty and all data on the phone so backup beforehand. You will see the first warning message at boot after this. There is currently no method know to relock the bootloader.
Download payload_dumper and extract it to c:\5z\. A payload_dumper-win64 folder will be created.
Download the firmware zip of the version you have on your phone and extract payload.bin from the zip to c:\5z\payload_dumper-win64\payload_input\ folder.
Start c:\5z\payload_dumper-win64\payload_dumper.exe and let it finish. Now copy the c:\5z\payload_dumper-win64\payload_output\boot.img to your phone (i will use the download folder).
Download Magisk Manager, copy the apk to your phone and use a filemanager on your phone to install it. Start the app and update it if you are asked.
When you are asked if you want to install Magisk > install. Select Method > Patch Boot Image File. Now select the boot.img in the download folder and let it finish patching.
Copy the patched_boot.img from the MagiskManager folder on your phone to c:\5z\platform-tools\
Start your phone in fastboot mode. To do that press and hold "power+volume up" to switch it on until you see the fastboot menu. If you are having trouble getting there,
it helps to release the power button first then the volume up when you see the menu.
Now connect the phone to your computer with the original usb cable. Open a command line with admin privileges and excute the following commands:
To switch to the fastboot dir:
Code:
cd c:\5z\platform-tools\
To check if your phone has been found:
Code:
fastboot devices
You should see the serial number of your phone.
Now flashing the patched boot image:
Code:
fastboot flash boot patched_boot.img
The output should look something like this:
target reported max download size of 268435456 bytes
sending 'boot' (18724 KB)...
OKAY [ 0.620s]
writing 'boot_a'...
OKAY [ 0.133s]
finished. total time: 0.756s
And the reboot:
Code:
fastboot reboot
Your phone should be booting now and you will see the second warning message "There is an internal problem with your device...".
If you want to get rid of that warning and do not need write access to your vendor partition (you most likely do not):
Open Magisk Manager and in the main screen press Uninstall > Restore Images to restore the images, check Preserve AVB 2.0/dm-verity checkbox in "Advanced Settings" on the main screen, then reinstall Magisk by pressing Install > direct install in the main screen.
Should you be stuck in the Zenfone boot animation or something went wrong, you will need to follow the steps in the unbrick section.
Otherwise your phone is rooted now. Enjoy.
[Downgrade/unbrick how to]
Download and extract the raw firmware.
With the phone in fastboot mode execute flashall_aft.cmd in the extraction folder.
You are now downgraded/unbricked with firmware 80.10.8.54.
Copy firmware version of your choice to internal sd card root and reboot/unplug usb cable to get "update notification".
Start the update to selected firmware from the "update found" notification.
[Downgrade/unbrick guide]
If you need to downgrade the firmware or if you have somehow bricked your device you can try to flash a raw (full) image of the phone.
Download and extract the raw firmware to c:\5z\raw.
If the download link is no longer working google for WW__ZS620KL_80.10.8.54_MP_user_20180517175955_release.zip and download it.
Start your phone in fastboot mode. To do that press and hold "power+volume up" to switch it on until you see the fastboot menu. If you are having trouble getting there,
it helps to release the power button first then the volume up when you see the menu.
Now connect the phone to your computer with the original usb cable. Open a command line with admin privileges and excute the following commands:
To switch to the fastboot dir:
Code:
cd c:\5z\raw
To flash the raw image:
Code:
flashall_aft.cmd
This will take a few minutes and the phone will reboot automatically. The first boot will take a little longer but your phone should now be unbricked and downgraded to 80.10.8.54.
You can now go to the root section of the guide and upgrade to a more current firmware.

Process is too long. I am working on unofficial Unlock Tool so that we can retain the warranty.
For downgrading, there is a tool for that. For me, fastboot codes may mess up the system/cache partitions.
If anyone wanna test my unlocking tool, feel free to PM me via Telegram

Yes it is possible but you will lose root.
Patching the boot.img for 80.11.37.79 and 80.11.37.86 does not seem to work with this method.

Warning - USE THIS GUIDE AT YOUR OWN RISK. I AM NOT RESPONSIBLE IF YOU END UP BRICKING YOUR DEVICE.
[Update 20.07.2018] I was able to root FW 80.11.37.86 with Magisk Manager 5.8.3 so you are no longer locked to FW 80.11.37.69 and do not have to downgrade.
This guide is split into two sections: rooting and downgrade/unbrick.
Each section is split into a quick how to for experienced users and a more detailed guide.
General info:
The most current firmware as iof 20.07.18 is 80.11.37.86.
I have only tested this on my ZS620KL Z01RD WW version. It should work on other variants JP/RU.
This guide is written for firmware 80.11.37.86. If you do not want to upgrade to 80.11.37.86 you will need to use the firmware you are on in all the steps.
Magisk hide is working and Safetynet check passes.
Bugs/problems:
Unlocking the bootloader will void your warranty!
You will get a warning message about your unlocked bootloader at every boot.
You will get a warning message about an internal problem every boot. Which you can disable if you do not need write access to the vendor partition.
> see rooting guide 10.

[Rooting guide]
You can root any firmware up to 80.11.37.86 with this guide. To upgrade to a newer firmware version copy the zip file (e.g. UL-Z01R-WW-80.11.37.86-user.zip) you downloaded from Asus
to the root of your phones internal memory and reboot or unplug your usb cable.
You will get an update found notification. Start the update. To downgrade check the downgrade guide below.
Enable usb debugging in System > Developer options. If you can not see System > Developer options go to System > About phone > Software information > Build number and tap it multiple times.
This will make the Developer options visible.
WARNING! Upgrading to some firmwares disables usb debugging and you need to enable it again.
Make a backup of all the data you do not want to lose.

Does unbricking lock the bootloader back since we will be flashing a raw a file.
With Magisk Manager 5.8.3 the whole guide works like a charm

How to wipe cache partition
Hi,
I am able to boot into recovery on Z5z but not able to see "wipe cache partition" option. I only see a wipe data/factory reset option.
I want to wipe cache to see if battery life improves. Can anyone let me know how to do this?
Thanks

I do not have any experience with mac os but if you want to root:
Adb/fastboot is available for mac os. All you need to do is find a tool to extract the boot.img from the payload.bin.
If you want to downgrade/unbrick: You would need to convert the bat/cmd files in the full firmware to some shell scripts and exchange the fastboot.exe.
How do I un-root, re-lock bootloader?

unroot: You press "uninstall" in magisk manager or install an updated firmware without patching boot.img or downgrade.
I have not tried re-locking the bootloader.
So if I'm getting this right, after unlocking the bootloader I will not get OTA updates.
But I will be able to download the latest version (SKU) from Asus and put it in /sdcard/ folder, and rebooting will start the update of the new firmware.
Is this correct?
Kind regards

You won't get OTAs + your warranty is voided (due to unlocking Officially)
Yes, you can update your phone by sideloading the zip from ASUS Support Website
