Bootloop after updating from B368 to B385 - Honor 9 Questions & Answers

Hi everyone,
I ran out of ideas with my problem, and could really use some help / advice with this.
Trying to updgrade my STF-L09C432 from B368 to B385 using HuRu updater, something went wrong and now it bootloops after the blue Honor logo.
Fastboot, Huawei eRecovery and TWRP are still working and accessible, my device is bootloader unlocked and says FPR unlock in fastboot mode.
So here's the detailed steps and procedure which I followed:
0) TWRP Backup of System + Data
1) Load three update files (FullOTA) via FF: update.zip (update.zip), update_data_full_public.zip (update_data_full_public.zip), update_full_STF-L09_hw_eu.zip (STF-L09_hw_eu/update_full_STF-L09_hw_eu.zip)
2) Create folder on SD-card with above files and TWRP v0.3 as recovery.img and the HuRu 0.4 zip file. Additionally I've left the HuRu 0.3 in the same folder renamed as HuRUpdater_0.3_old.zip
3) Installed the HuRu 0.4 from TWRP with zip verification disabled (tried before with enabled, but it failed -> call me stupid but I've double checked the checksum with a new download, so I took the risk).
4) the installation log showed warnings about some missing .zip files, but I ignored those as well, as I've never heard of them and didn't have them from FF.
5) rebooted the system and caught the first bootloop
Now I tried myself to fix it the following way, but unsuccessful until now:
1) Flashed TWRP into recovery_ramdisk because I didn't know the right procedure to boot into it
2) Flashed the new B385 versions of KERNEL.img, RAMDISK.img and RECOVERY_RAMDIS.img which I extracted from the UPDATE.APP -> still bootloop
3) Flashed TWRP into recovery_ramdisk again because I still didn't know the right procedure to boot into it
4) Flashed the old B368 versions of KERNEL.img, RAMDISK.img which I extracted from the UPDATE.APP, but not the RECOVERY_RAMDIS.img this time -> still bootloop
5) Then I've managed to boot into TWRP finally, and tried to restore my previous backup as a last resort, but that still didn't resolve my bootloop
Anybody has any idea what I could still try? Maybe I'm missing something obvious, or I'm still to new to this to see what is wrong.
If possible I'd like to keep my data intact, but I could probably extract most of it out of the backup, if nothing else helps.
Thank you very much!
Best regards,
Chris

Nobody has an idea?
Maybe the Seniors on the Honor9, @OldDroid or @zxz0O0?
After I've tried to restore the previous TWRP backup, now also TWRP won't boot anymore, therefore I'm stuck with fastboot or the Huawei stock recoveries...

well, aslong as its still unlocked (frp & bl) i'm able to help.
Do you have telegram? if so, send me your username through pm.

I managed to get into TWRP again when I've installed the latest kernel and recovery images. After that I've realized that I still had Magisk installed and Active.
Uninstalling that solved my bootloop for now.
Unfortunately my backup restore just returned me to the previous version B368 which I already had installed... so lets see what happens if I apply the update again
---------------------
Edit:
Update applied, without magisk installed, still bootloop... At least the way back was quicker this time
Any hints what's going wrong are appreciated!

L22 Marshmallow - System update failed

Hi,
Today i received a notification on my L22 to update to Marshmallow (310).
But when it reboots into recovery (stock), it says system update failed.
Note:
I have rooted my phone and installed custom rom before. But i used to get back to stock (both rom and recovery) with a TWRP restore. This has worked with all the previous updates of Lollipop (e.g. 130 to 150), but its not working with Marshmallow.
Can someone please help!!.
Can someone please help. I hope this is a beta version. Actually I had opted for the beta previously.
there are no restoration files zips for MM yet, alternatively, you can flash TWRP back via adb and restore your back up. else, follow the steps in thread below....good luck!

Thank you @nandakalyan @Arobase40 for the information.
I can check with them. But when i tried to login to their community, for some reason, my login credentials weren't recognized.
As an update, I tried the following
I downloaded the lollipop 150 firmware and flashed the BOOT, RECOVERY, SYSTEM and CUST image files. But I received REMOTE: COMMAND NOT ALLOWED error while flashing CUST. I even tried installing the USB/ADB drivers again. Still no luck.
Then i tried the update. Still the same error.
Again i followed step 1, then relocked the bootloader (successfully). But still got the same error. (Because i read somewhere that it could be due to modified firmware)
Looks like some issue with the package. So i might have to get back to them.
I will post the update once i get the update from them. Thank you very much guys.

The CUST image file can't be flashed !
But I saw someone was able to rebuild the /Cust folder and its content but I'm too lazy to do the search...
It's in the Honor 5x thread.

That is correct, cust.img can't be flashed through ADB, I have had this issue too.
@mani0608
The only best way is to flash stock recovery, create a dload folder in the root of the sd-card, place the update.app (original firmware file) in it, boot into download mode (power + vol up + vol down) and let the whole factory image be flashed.

Honor 9 no OS installed, TWRP and fastboot with unlock still working

Hi guys, i got my H9 yesterday and because i thought i read enough on this forums i wanted to unlock it then install TWRP and install superSU to gain root access and stick with the stock firmware.
Unlocking went perfectly fine,phone booted to OS, than i flashed twrp 3.1.1-1 as advertised here and made a factory reset. Phone was stuck in bootloop for unknown reason.
I made several wipes and somehow managed to check all boxes in the wipe menu which erased the whole OS.
Now i read here that others have the "no OS" problem too but because i still have all unlocked fastboot and twrp i wanted to ask which method is best to flash back the original FW.
Which stock ROM is safe to install? i have european H9 is STF-L09C432B170 the right one for me?
Which method is the best to install it? Copy the 3 zips to internal stoagre via OTG device and install it out of twrp? I read that there is also a force method where users can push vol up, vol down and power simultaneously and enter the huawei install force mode.
I am quite sad that the phone was stuck in bootloop after twrp install and still dont know what caused it. When i install it from twrp there are 3 zips: update, data full public , hw eu. In which order do they have to e installed and is one of them overwriting the TWRP recovery?
Please give me a short hint/procedure, im quite afraid that i cant get my phone back to work and it is brand new. I dont know what caused the unsolvable bootloop.
Best regards and many thanks
Hi.

This help you.

thanks for the hint but i cant find a solution for me there.
ut this
i copied the 3 .zip files to internal today but TWRP doenst allow me to write them it fails with "write err errno 9"
then i tried to copy the update.pp in DLOAD folder on micro sd but this is not possible because filesize is over 2gb. i tried to format micro sd with twrp to exfat but it till doesnt work. please give me a little hint what to do im completely desperate about the situation.
Today i installed Huawei Multitool and extracted the .img file out of the update.app files, i was able to flash all 4, system, boot, recovery and cust.
Now the rec. menu is back to stock and everything got installed but the phone still isnt booting. i think it is because i missed the userdata.img which i cant find anywhere.
Other users here have the same problem. Is there a firmware package which includes all 5 .img data?
Best regards
i found the official huawei service full repair firmware with all necessary files for unbrick (system, cust, recovery, userdata, boot) flashed them via fastboot but stil device is "hanging" after the warning message that its unlocked. i think it is because i wiped vendor data in twrp but i cant flash vendor.img in fastboot. it is included in the fw package but cant be transfered to phone via fastboot. it stops at part 1/2 because the filesize allowd is around 470mb max but the extracted file has a size of 670. anyone know what to do?
Best regards
You need to go via the Rebrand way with no rebrand. I had the same problem and was trying to use the multitool without success. The oeminfo can be flashed alternatively if it fails during the HWOTA process.
https://forum.xda-developers.com/honor-9/help/how-flash-oeminfo-t3657499
ok i download all the folders with the .bat file. Then i download C432B150 from the czech site and add it to the update folder. Than i rename the 3 files accoding to the manual and run the .bat file but without rebranding right?
Des this tool any different than the HuaweiMultiTool or fastboot with flash command?
Best regards
I treid out HWOTA, the first step installing twrp is successful than i disattach usb cable as described and enter twrp. Then it says in twrp i have to connect again and press enter but then the bat file stops and doenst go on. i dont come to the point where i can choose rebrand or flash firmware.
Whats wrong here?
edit: i saw in the .sh file that the script executes wait_adb but my phone is not entering adb mode as it seems when in main screen of twrp. is this normal or do i have to set it manually in twrp
best regards
I was able to install the B130 now via 3 button recovery. Now im on B130 but cant update elsewhere. Also the 2 capacitive buttons are not working. Bootloader is locked again. Everything is stock and the phone runs great. When i update with the 3 buton method from external sd, which firmware should i use? i tried B150 full OTA but it aborts after 5% with an error. Do i only need to get a small OTA package now?
How can i put my cap. buttons back to work? Too bad only the 3 button method worked to recover the phone.
Best regards and many thanks.
I did the HWOTA with b120 firmware and then used firmware finder to update to b150.
The bug with capacitive buttons is present till Oreo. I use the home button gestures anyways.
Hope it helps.
ok, thats bad but they worked with the initial revision of b130 and b150 when i downloaded it OTA. Is this something like a fuse like.knox at samsung which happens at custom flashing?
Sent from my GT-I9300 using Tapatalk
the HWOTA method doesnt work, the batch file gets stuck after connecting the phone in twrp back to computer. in script it says wait_adb but it is not recognized somehow.
do u know a solution? anotherone here got that problem too.
im very afraid of that, i read here that everything related to twrp 3.1.1-0 and 3.1.1-1 is problematic a lot of people cant boot after installing twrp and can wipe whtever they want the phone never boots fully
whats the difference in the B130/B120 the phone came from huawei and the version flashed via tools? when i got it everything worked
i have this version.
ok so install twrp have frq and bootloader unlocked and then do backup out of recovery? with your file? can you provide download link? is this then a zip file?
I want to solve the thread and how i solved problem.
The B130 service firmware by huawei could be installed via 3 button method, than i was able to go up to the newest B180 via firmwarefinder and DNS method but with not working cap. buttons and flash etc.
Yesterday i installed TWRP 3.1.1-1(temporary) via HWOTA.zip method (ireplaced the older twrp in recovery folder) and successfully installed B120 and got the buttons etc working again. Then installed root and now system works fine and is rooted. My mistake was to install twrp over B130 or B150 which i downloaded OTA at the first day i got the phone. I tested this yesterday to install TWRP along with B150 and unlocked bootloader, infinite bootloop again. With B120 the TWRP 3.1.1-1 works out of the box without any loops.
The 2 trouble solvers where B130 service firmware and HWOTA with B120.
The external SD had to be inserted in card reader on PC because of the large filesize of the B130.
I would recommend to everyone before starting to play with the H9 to move the B130 folders to phone while it is still accessible. When everything bricks like in my case and u still have twrp than you can go to twrp main screen and connect phone to computer to rename the folder with B130 to "dload" and arrange update.app accordingly on PC or in TWRP file manager.
Can i set this topic to [SOLVED] myself?

It was all going so well too... Help with a boot loop brick atm :)

Hi all,
I went ahead and rooted my Mate 10 Pro today - I unlocked my bootloader, installed TWRP and got it running pretty sweet. Then, like a tool - tried installing xposed framework and got myself into a boot loop.
I can get to fastboot, I can get into twrp - but for the life of me don't know how to get a system wipe and fresh format! I've tried flashing LineageOS - but that's stuck on a loading screen and then boot loops after about 10minutes.
What happens is I turn my phone on - see the bootloader message - if I do nothing there's a 50/50 changes Huawei's eRecovery window opens (where if i connect it to the wifi, it fails and gives me the option of reboot or shutdown) or LineageOS boot animation loops for about 10minutes before shutting down.
At this stage, I don't mind what rom i get working - i just want something working and I'm really regretting xposed (I should of googled!).
I really don't want to pay $40 usd - and am happy tinkering around, but would appreciate some solid advice on how I can use TWRP to wipe everything and start again!
I'm also a little confused as to why eRecovery is coming up at all - and why it can't download anything!!!!!
Can someone help me get a phone back?
Thanks!
Yeah, I bootlooped going with xposed too, but I have the Mate 10 (regular) and no TWRP. Can you get to TWRP and simply flash a clean ROM? If not, which I presume is the case, can you get to Fastboot? To try, when you get to the eRecovery window, use the option to shut down your phone. Then press the power button and, while holding it, plus in your USB cable (the other end which should already be attached to your computer). Then go to Mankindtw's thread for flashing ROMs (Mate 10 Flash Oreo one). Basically, you download three zip files from a russian language page with all the latest Huawei ROMs, repackage them within his utility, and then flash them from within his utility. Worked for me.
download update.zip (for your firmware) from http://pro-teammt.ru/firmware-database
Extract update.app from update.zip
Download Huawei Update Extractor (open it and go to settings and disable header check)
Open update.app in Huawei Update Extractor
Extract SYSTEM from update.app using Huawei Update Extractor.
(Not sure if Xposed modifies vendor too, so you might have to extract that as well)
Fastboot flash system system.img
See if it boots now. If not you could try extracting recovery_ramdisk and flash recovery_ramdisk.img to the recovery_ramdisk partition then factory reset from stock recovery.
If it does modify vendor you'd have to flash vendor as well.
Or you could try flashing lineage os system, flash recovery_ramdisk and factory reset from stock recovery (factory reset is needed to get aosp roms running)
If it still fails, use mankindtws HWOTA as described by rogerinnyc above. (link: https://forum.xda-developers.com/mate-10/how-to/guide-mate-10-flash-oreo-update-package-t3716814)

The problem I'm having now is, on my win7 and win10 pc's - when I enter fastboot, neither PC will accept drivers for it and therefore, I can't fastboot flash anything.
I just get '<waiting for device>' even when plugged in (and windows 'driver no successful' message)
Is there a way to transfer the files via twrp adb sideload?

Sadly no, this corresponds to reflashing the whole phone, block by block.
have you tried to find matching drivers ? (it should be pretty easy on windows 10 normally...)

Install this regfix https://www.dc-unlocker.com/huawei-mate-10-fastboot-usb-device-not-recognised-fix
However, you would probably have had problems before too when flashing twrp.
But worth a shot I guess.
Didn't see it said you tried on win 7 too.
And if it worked before on Win 10 it should work without it.
I guess you could push system.img to /data/system.img then tap Install and selectInternal storage, tap on (go up one level) in browser, now you'll be at /. Tap on /data and then on system.img. Flash to 'System Image'.
Edit: I've tested with recovery and that flashes fine from /data/.
please see below;
Hi all. My SDCARD was encrypted in TWRP, so I googled and saw I should run this command;
recovery --wipe_data --set_filesystem_encryption=off
Which I did on TWRP terminal - and now im boot looping again. I tried fastboot system.img and it's still bootloading. I see there's supposed to be a 'boot.img' in my update.app, but there isn't.
Any ideas?

Boot.img is for Nougat. Oreo uses ramdisk.
Try wiping data in TWRP (Wipe - Format Data).
You can't turn off encryption in TWRP. It's controlled by /vendor/etc/*.fstab (* = kirin970 in this case). (You can temporarily turn off encryption but it re-encrypts after booting if fstab is untouched)
But removing encryption won't fix you bootlooping, and that command you used is for Full disk encryption, we use file based encryption.
You could also try flashing back stock recovery and do factory reset from there.
Edit: Oh, you're the guy who PM'd me
I've reflashed my 'system.img' as before - but im having trouble getting into factory reset menu.
all it ever does is go into e'Recovery instead, which is useless.
Also, my booting image is still a green page of pixels - rather than a huawei logo.
Hi. I have a bla-a09 and need help. can boot into twrp but will not boot.

[TWRP][RECOVERY] Asus ZenPad 10 Z300M, Z301M & Z301MF (locked bootloader ok)

This is basically a copy of my Z380M TWRP thread adopted for the ZenPad 10. I decided to start a new one since the OP of justshaun's original recovery/rooting thread has gone stale, even as I had posted several new releases of TWRP over the months. Its instructions are also a little outdated. I've also compiled a version for the new Z301M(F) models and needed a place to post it. This is where I will be posting TWRP updates from now on.
In addition to this thread, referring to the Z380M TWRP thread and the original Z300M thread (links above) may be helpful. These models share the same hardware and software base, so most things that apply to one tablet also apply to the others.
DISCLAIMER
As usual, you do anything described in this post at your own risk. No one but you is responsible for any data loss, bricking or damage of your device.
REQUIREMENTS
Windows or Linux PC
SP Flash Tool version 5.1532 (only this version will bypass security checks)
MediaTek VCOM drivers (available through Windows Update)
ZenPad 10 scatter file for SPFT, attached (choose the one for your tablet)
Recovery image, attached (choose the one for your tablet)
ZenPad Z300M, Z301M or Z301MF tablet upgraded to Android N
This won't be a guide on how to use SP Flash Tool. There are plenty of good guides out there like this one on how to set up drivers, load scatter files, flash and make backups with SP Flash Tool. If you're not familiar with this software or how to flash MediaTek devices in general, please do your research before attempting this. I will just get straight to the specifics about the ZenPad 10.
FIRST TIME INSTALLATION
For a locked bootloader:
At this point you should have your tablet powered off, the drivers installed, all of your data backed up, and SP Flash Tool v5.1532's Download tab open and loaded with the tablet's scatter file. Open the download agent file DA_PL.bin, replacing the default MTK_AllInOne_DA.bin. (You can use the AllInOne DA if you want, but the procedure involves extra steps as described below.) Load the extracted TWRP recovery image for your device (twrp-3.2.1-0-z30*m.img) under the recovery partition line in the partition table. Click the Download button inside SPFT. Now just connect the USB cable to your tablet and your computer's USB port. It should start the download process automatically and disconnect when finished.
Alternative Method:
If you're using MTK_AllInOne_DA.bin, you have to hold the Volume Up key as you insert the cable, which puts the device into an emergency download mode. In addition, you will need to have the stock preloader*.bin file loaded inside SPFT for it to be able to communicate with your tablet. The preloader is available inside the official zip file download. Do not flash the preloader (untick the box) or any partitions other than recovery. You just need to have a valid bin file selected under the Preloader line.
For an unlocked bootloader:
If you have used the Asus unlock tool to unlock your device, you will still not be able to use fastboot flash to install a custom recovery. However, you can do a "hot boot" or a tethered boot of TWRP. This method doesn't require SP Flash Tool. Download the TWRP image, put your tablet in fastboot mode and connect to PC. Then run this command to boot TWRP dynamically:
fastboot boot twrp-3.2.1-0-z30*m.img
Once inside TWRP, flash twrp-3.2.1-0-z30*m.img to Recovery using Install -> Install Image. Then reboot to recovery. You may be able to use TWRP in the tethered boot mode, but that could result in glitches due to different parameters passed by the bootloader to the kernel. That's why flashing is recommended.
To update from your installed TWRP version to a new one, just transfer the image to your tablet, then boot to TWRP and install it by going to Install -> Install Image and flashing to Recovery.
START RECOVERY
With the tablet powered off, hold the Volume Up and Power keys together until you get to a menu where you can select "recovery". On the Z301M/Z301MF, that option is labeled Factory Reset. Use Vol. Up to scroll and Vol. Dn to select. If you have a locked bootloader, it will show a Yellow State message because the recovery is not signed by the OEM. Just press volume up to boot it. On the welcome screen of TWRP it will ask you about modifying the system partition, I suggest you go with Keep System Read-only. Doing otherwise will complicate your OTA updates.
WARNING: Never start the stock recovery from the bootloader menu on this device. It is programmed by the bootloader to instantly wipe your data without any warning. Also, be aware that Android installs the stock recovery at every normal boot cycle. So you either have to flash the TWRP every time you want to run it, or disable the automatic recovery installation in the stock firmware. Any kind of mod to the boot image will prevent the automatic recovery installation. If you're not sure which recovery you have installed, you can always do a 'adb reboot recovery' from Android without risk of data loss.
WARNING 2: Make sure you use the correct scatter file for your device (i.e. don't mix up the Z300 and Z301 files). For the initial flash, there is no check for scatter file correctness. If you use the wrong one, SP Flash Tool will alter and lock your GPT to that scatter file layout, possibly bricking your device. It will not be easy to restore it. Flashing with the correct scatter file later on will not work because Flash Tool will not allow you to use a different file than the one you used initially.
What works: Basically everything... access to major partitions, decrypted userdata partition, decrypted adoptable storage, external SD card, ADB, USB-OTG, touch interface, splash screen, installing stock Asus OTA/web FW updates
What doesn't work: (no known problems yet, but please report any)
Not guaranteed to work: factory reset

Heya, thanks for the new thread..
Stupid question(coming from Samsung flashing)
Ive got Zenpad S3 10 P027, is this TRWP not ideal for this?
Currently, have some su (root) issues. Recovery shows Android icon chest with ! and says "No Command"
When running su in Terminal ADB via PC, says command not recognized.
Looks like I need to reflash recovery. When in TRWP (launched via fastboot boot twrp on PC) I flashed stock recovery but had system mounted read only. Could that be the problem?
Bro, I think you need to do some more homework on root, su, dm-verity, mods, etc. and read the instructions more carefully before applying these hacks. You are making a lot of simple mistakes and ending up shooting yourself in the foot for it. I don't think there's anything wrong with the Z500 TWRP. It can handle installing the stock firmware just fine. The problem is elsewhere. The unlock tool also works fine in TWRP as well in my testing.
The No Command screen is normal. That's been answered many times... you need to hold power+vol. up (or down) to get to the menu. There is no way the stock recovery image can be broken and still boot up.
The su thing, IDK what the problem is, but I'm sure if you install Magisk Manager and make your own patched image from your currently installed firmware, and fastboot-boot with it, you will have su functionality. Just like what it says in the unlock tool instructions.
Lastly and most important, never mount system in read-write mode, as I've repeated several times and exactly as it says in the directions:
7. At the TWRP welcome screen, do not select to modify the system partition and touch Keep System Read-only instead. Doing otherwise will render your tablet unbootable.
8. Mount system in TWRP (in read-only mode)
Click to expand...
Click to collapse
The only time you can mount it in read-write mode is when you are absolutely sure you have disabled dm-verity in your boot image.
I've successfully installed TWRP on Z301M using the instructions from the first post, but then I somehow managed to lose the system. Yes, I should have backed up like the OP suggests.
I thought I should be able to reinstall the original firmware downloaded from Asus (e.g. UL-ASUS_P028_1-WW-3.3.12.0-user.zip) but both the 'adb sideload' method and the TWRP failed to install that firmware zip. My device looks bricked. The only thing I can do is to boot into TWRP (I actually need to select Factory Reset on the bootloader screen to get into TWRP). The folder 'system' is empty.
Can anyone suggest what I am doing wrong when trying to restore the Asus firmware?
When I try to sideload the zip, setting TWRP in the sideload mode, the computer begins uploading but after a few seconds gives the message "Total xfer: 0.01x" and stops, while Android errors with "set boot part fail. can not open misc-sd".
When I install the firmware zip from TWRP it also starts installing fine but shortly gives the same error "set boot part fail. can not open misc-sd".
Thanks
@ahacker, first of all, thank you for the feedback on the Z301M platform. You are literally the first person to have said anything about that version of TWRP.
To see the files on system, you first have to mount the system partition. Did you do that? If not, I suggest mounting it read-only. If there was any corruption on it, then reinstalling the firmware should have fixed it. The "misc-sd" errors are normal. Pretty sure they happen on stock recovery too. The stock firmware does not have dm-verity enabled, so letting TWRP modify system to prevent overwriting recovery should not have caused any problems.
At which point did it stop booting? Also, did you use the scatter file from first post? And can you tell me if the touch screen works fine in TWRP on your tablet?
I'm not sure what the deal is with adb sideload. I don't think I've ever actually tried it....
diplomatic, thanks for replying!

To see the files on system, you first have to mount the system partition. Did you do that?

I do mount the system partition. It appears empty. When I reboot into system TWRP says that the OS is not installed.
I don't remember the details of how I lost the system partition. First time I entered into TWRP it asked for a password, probably to mount some partition. I pressed cancel or something. Then I might have cleaned the caches. But I am sure I haven't wiped system. I might have pressed Factory Reset somewhere, because I don't have any data yet on the new tablet.
I would indeed try to mount the system read only. This is not the first Android system I rooted (maybe fifth), and I was always able to restore the system either from sideload or recovery. But here it seems Asus is making us jump extra hoops to do that.

Reinstalling the firmware should have fixed it.

That seems to be my main problem now. I cannot reinstall the Asus firmware. It may look like I might be installing a wrong version, but I am positive that I have Z301M tablet. This is what I bought and what the boot-loader says. I download Z301M firmware from the Asus website (e.g.). So it must be a correct firmware.

The "misc-sd" errors are normal. Pretty sure they happen on stock recovery too. The stock firmware does not have dm-verity enabled, so letting TWRP modify system to prevent overwriting recovery should not have caused any problems.

Yes. I found that to be the only scatter file that worked. I tried scatter.txt from the firmware zip, but the Flash Tool refuses tio pick it up. TWRP seems to be working fine with touches working as expected.

This is the unbricking method described here. It probably does the same thing as the "Install Zip" from recovery, because the errors that both methods give are the same.

Er, the password should have been for decrypting your userdata. If you didn't have one set up, there might be something wrong there.... Or possibly just unformatted.

Yeah, that has to be the right one. The installation script has to match the model name reported by the recovery. Otherwise it would simply abort.

Great! Guess my kernel patch was on the dot and the partition layout has not changed from the Z300.

When you installed the zip, did you unmount system completely? BTW, when you mentioned the errors, the installation does keep going for like 5 to 10 minutes afterwards, right?
If you still can't resurrect it, please post or send me the recovery & kernel log that has your installation attempt.

I've tried both ways, with and without system mounted, a few times. The installation would fail after something like 5 seconds.

I think I am giving up on this cheap tablet. I cannot even format it in the Flash Tool: it says "To format code area is forbidden on this phone". Asus is forbidding too much for me to ever buy it again. Attached the logs.
Thanks, diplomatic
OK, found the problem. Check your PMs, ahacker.

i not understand... i have Asus ZenPad 10 LTE Z301MFL.. a root method has been released ???
@diplomatic
Would this be compatible with Z0310M ? can't find anything for this damn model...
Hi, NeBouse,
Are you sure you have the correct information? It looks like just a misspelling of Z301M, aka P028....
I have z301m.
One thing that was a surprise for me is that the TWRP recovery flashed with the method described in the original post does not stick. You have to flash it each time you use it. If you are like me this information is important, because the original recovery plainly wipes your data without asking or warning.
After you have flashed TWRP on the device, to go to the recovery mode you have to chose "Factory Reset" in the bootloader. Then it will complain about wrong OS, which is the sign that flashing TWRP worked; choose 'yes'. The first thing you should do in TWRP is a ful nandroid backup. (Not listening the OP's advice about backing up when Installing TWRP with a wrong scatter file almost cost me the device. Thankfully diplomatic managed to remotely fix my problem, probably spending a lot of his personal time. The scatter file in the original post is a correct one now.)
Creating a nandroid backup in TWRP takes unusually long time, I even once decided that it hanged. Taking long time, like 10-30 minutes, for a full backup is normal.
Asus Z300M , Magisk 16.3 (beta) and FW 5.3.19 WW now works!
z301m, WW-3.3.12.0 firmware
For rooting I've installed in TWRP Magisk v15.3 (diplomatic warned against 16.x, someone else against 15.4) - link.
Installed in TWRP xPosed framework 88.2 - link, and xPosed Installer apk from within Android - link.
So far, so good.
What I've found is that TWRP seems to have problems with external sd cards (lots of fs corruption). I found it safer to unmount by hand by unticking the sd card checkbox in "Mount". Not very conclusive about this though.
Thanks, ahacker. Good feedback. Although to be fair, I didn't say to avoid Magisk 16.x. I said 16.0. I'm pretty sure whatever bug it had is already fixed in the latest version.
Now that you've installed root, TWRP will stick around on the emmc. The stock recovery only gets installed if you have the original unpatched boot image on it. I mean, this is not unique to these devices. That's been standard Android functionality since some 4.x or 5.x version. And this is essentially what's in the warning on the OP.
The backup I'm talking about in the installation method is done with the SP Flash Tool readback function. That will pull the partition tables and your device's "metadata" that's unique to your unit. I don't think nandroid covers that...
Oh, and what is this SD corruption you're talking about? What file system is it formatted in? Have you checked your card for errors in Windows?
Asus releases so many difference Z301M model, so I am curious if this also works on Z301MF model?
Notice Z300MF has the MTK8163BA (or MTK8163A?) CPU model while Z301M uses : 8163B
Anyone tested that already? Thanks.
my zenpad 10 has frp lock. it this a solution to remove the frp lock?
Pls help how i flash original software via fastboot ?????

TWRP errors when trying to restore boot - bricked phone

I've bricked my phone and am in need of help!
What I've done:
Unlocked bootloader with a code from DC-Unlocker then using minimal ADB and Fastboot to unlock
Flashed TWRP 3.1.1
Installed Magisk
Took TWRP backup - but I was unable to backup Data (I believe this was due to encryption - recovery.log shwed errors initially on Bluedorid files)
Wiped data with TWPR to try and do a factory reset
This is where my problems started and now I cant restore boot with TWPR the error is "No such file or directory"
I can ADB pull my recovery.log which says
Read info file, restore size is 12444160
Restoring 6 partitions...
Total restore size is 4512MB
I:Restore filename is: /external_sd/TWRP/BACKUPS/L5NDU17B18000539/Stock V7 2018-06-23--16-58-45/boot.emmc.win
I:Restore file system is: 'emmc'.
I:Restore file system is: 'emmc'.
Restoring Boot...
Error opening: '' (No such file or directory)​
I can restore OEM recovery and do a factory reset but it hangs at 99%
power down then it goes back to factory reset and goes to 100% - message "Reset Successful!"
but... then it gets stuck in a boot loop
I've tried downloading other stock ROMS and extracting and flashing images via fastboot (Boot, cust, product, recovery, system, vendor, version)
I've tried Huawei Multi-tool but I lack the Userdata.img disk image
I've tried flashing Resurrection Remix N v5.8.5 For Honor 9 (STF) but without success, although the TWRP install says it is successful and the vendor.img flashes fine.
I've tried extracting UPDATE.app files and putting them in sd_card/dload and then 3 button resetting
I've tried the above in external_sd/dload (not sure why - desperation)
I've tried looking on as many threads as I can find on XDA but with no luck
I can always get to fastboot, flash TWRP or OEM recovery, I can also run ADB commands via Putty (in command line they display strangely)
Any suggestions would be greatly appreciated! I am at a loss an quite frustrated, and have been working on this for maybe 15 hours now.:crying:
LOL, Stop your mumbo-jumbos.
I guess you'r still with nougat partitioning because you're using a pretty much outdated twrp.
So just dload flash a nougat 'service repair firmware' from the same region you're firmware is actually, and not any random update.app you 'made' yourself.
For this you'll need a micro-sdcard (or usb-otg) exfat formated :
https://forum.xda-developers.com/honor-9/development/firmware-huawei-honor-9-stf-l09-stock-t3696892
Fixed!
Thank you, I think I even saw this thread but for some reason did not download the file, also the exfat formatting tip was excellent. I owe you a beer!
Can I always use this method to go back if I totally destroy things again even If I update to Oreo?

Unfortunatly, there only nougat 'service repair firmware' available publicly as far I know.
So, for now, you can only use this when on nougat.
When on oreo, you should use HuRUpdater with oreo's Twrp.
Or if you're oreo device is really messed badly, a paying app called DC-Phoenix then HuRUpdater.
