So in looking around I have not found any answer to my question. Why is everything to flash on the shield a .img instead of building zip files you can flash directly from recovery? I have been messing with android for quite a long time and know how to flash .img, fastboot, adb, ect. But dl'd and flashing a zip is far easier.
Any answers?
thanks.
*I think* that base factory images (.img files.) are meant to be flashed via fastboot, since they have a direct relationship with device specific partitions. Imagine a bit to bit flash, like a Ghost/Acronis image?!?
As for .zip files, they are installed via recoveries (CWM, TWRP, etc), because you just want to add/replace files in the / partition.
And with our Shield, until now, all OTAs are full system images, not updates.
I hope that I've explained this properly, if not please someone correct me

Not all ota are full system images, ota 65 and 67 are simple delta updates.
BTW, the main reason of .img files for images is because this can't depend on the recovery. How do you flash a recovery .zip file without a recovery?
You need to have a .img file that can be flashed via fastboot, it is VERY much "bricked" proff that a flashable zip
Thanks for the explanations. I realize some things need to be done via fastboot like unlocking or flashing a recovery for the first time.
I guess I have become spoiled by xda and the simplicity of modification that is available today. Far cry from hacking htcs back in the day.
thx -jason
Both answers are correct - it all depends on which software (on the device) is used to flash, and what format it accepts.
With Tegra devices you have at least 3 ways to flash stuff, from lowest to highest level:
- nvflash/tegrarcm mode. This is a very small firmware that is burnt in ROM and is thus always available no matter how hard you screw your device. It can run small programs (typically, a flasher) that are sent through USB. Problem is, for Tegra4 it will only accept signed binaries, which makes it useless for modders.
- bootloader/fastboot. The bootloader supports the fastboot protocol, which can flash .img files. The bootloader is written in flash memory so your bootloader partition must be in good shape.
- recovery/zip files. The recovery is a Linux image, so this means it is a full-blown system of its own right. Because of this it can support more format, including .zip archives with a script to describe how the archive should be installed.
So in the boot chain, you have 3 anchors from which you can flash images: boot rom (always available but unusable to us) -> bootloader -> recovery. The fact the boot rom cannot be used without a signed image (which is not available publicly) means that screwing your bootloader is sufficient to permanently brick your device.
Recovery images are more convenient since they are in .zip format and can for some be device-independent (e.g. superSU recovery images are flashed the same on every single device out there), contrary to the bootloader which can be different for every device. But they require a working recovery, which is not always granted - so for actual recovery, fastboot images are also useful.
That's why I love XDA
You're never alone!
Thanks for the additional info to all

Hey Guys -
I have had my A9 for about 2 months and love it. When I first purchased it, I rooted it using the method pinned to this forum which seemed to work well. Soon afterwards, I found out that when I inserted and tried to format an SD card as "internal", it wouldn't work and result in it showing as "corrupted." I soon found out that this seemed to be due to the root replacing the original boot.img which messes with encryption. Since the root was posted, SuperSU has been updated and that step has changed supposedly.
Now that I have some time, I want to fix this issue. Before doing so, I've read through many posts and think I have a plan. I wanted to post the steps I need to follow as I understood them to make sure my plan is correct and will result in not only being able to format an SD internally and be rooted, but also a working phone Below are the specs of my phone, the steps I think it may take to resolve, and a few questions I have after reading through numerous posts. Any help is appreciated!
Phone Specs
Some as currently listed in Settings
- HTC One A9
- AT&T USA
- Rooted / s-off
- Android 6.0 / Sense 7.0g
Software Number: 1.10.502.3
Kernel: 3.10.73-perf-g28d66e0
Baseband: [email protected]_29.05_F
Build: 1.10.502.3 CL635081 release keys
Android Security Patch Level: 2015-10-01
Steps to Fix
1. Backup any data desired (I have a nightly Titanium backup)
2. Download RUU for same version (1.10.502.3) from http://forum.xda-developers.com/one-a9/general/wip-ruu-htc-one-a9-t3240344
Should I use newer version or are those for different carriers?
3. Apply RUU (via embedded EXE or try to extract and apply using adb/fastboot)
4. Once phone is restored, make a backup of boot.img from phone just in case it's needed later
5. Install TWRP via adb/fastboot
6. Install SuperSU via TWRP
At this point (if I can make it to this point), test and see if the phone's rooted and I can format the SD internally. If so, great. If not, continue with the following steps...
7. Download & flash modded boot.img from A9 Root post
8. Install TWRP via adb / fastboot
9. Install SuperSU via TWRP
10. Flash original boot.img backed up in step #4 to my phone (since modded one was only needed initially to install SuperSU) So that encryption keys match and I may successfully format sd cards for internal use
My Questions
1. Are the steps above basically the process i need to perform or is there a better / easier way? I don't know if I could flash a common boot.img from an RUU or if it needs to be flashed to phone first for encryption purposes. Even if I can, I've tried to extract it from ruu.zip before and could not
2. Should I use an RUU for a newer version (over 1.10.502.3) or are those for different carriers and not work with my AT&T phone?
3. Does it make a difference if I install the RUU via embedded EXE or extract and apply using adb/fastboot?
4. What versions of TWRP & SuperSU should I use?
Any additional suggestions would be appreciated - I just want to get this resolved once and for all! - Thanks!

First off, this isn't Development.
Secondly, I explained to you how to fix this in the very root thread you linked several times.
Thirdly, there's a newer, official RUU from HTC right on their ROM Downloads website. I'd start by installing that (though I also have a recovery-flashable version of that ROM in my Base ROM thread).
Fourthly, with access to an official RUU, and my ROM decrypt script, you have access to the stock boot.img (which is also in the firmware zip in my Base ROM thread), which you can use as your baseline for restoring the verity key to the ramdisk, thereby allowing you to use adopted storage without any issues. Note however that I was only able to use adopted storage with the "forceencrypt" flag enabled.
Fifthly, you can't just restore the stock boot image (at least not if you want to stay rooted). You can be both rooted and encrypted, but you have to first make sure SuperSU is flashed and set up prior to allowing the device to be encrypted again (adopted storage only works with an encrypted device, and then you won't be able to access your storage with TWRP).
OK, OK - sorry.... It had been a while since posting and honestly forgot about that thread - my fault.
I decided to start fresh so have already restored the phone to HTC's latest RUU (1.27.502.5 ATT) as I already had it downloaded. I've also flashed TWRP 2.8.8.1 to the phone, but am obviously prompted to enter a password when I try to enter recovery. Based off what I've read, the steps below seem to be what I need to do so that I may be rooted + still have encryption for internal sd formatting. Is it correct (or close to it)
Using an Ubuntu 14.04 x86 VM...
1. Download & extract your decrypt script to a temp folder in linux vm
2. In Windows, run same RUU I applied and copy out rom.zip from %temp%
3. Rename "rom.zip" to "rom_a9.zip"
4. Copy rom_a9.zip to the ""place_rom_zip_here" folder of your extracted script in the vm
5. Run ./decrypt-htc and wait for script to complete to get img files
On Phone (Currently has same RUU installed + TWRP but not rooted)
6. Root phone using original method of flashing modded boot.img, install SuperSU, and get rooted
7. Once done and rooted, flash boot.img I extracted using your script above to phone via adb
Once that's done, it should be rooted + have encryption thus allowing me to use internal sd card, right? Sorry to be such a bother - just want to get this fixed and done with
Thanks!

Re-read my post. If you flash the stock boot.img, you will no longer be rooted.
And as I said in the original thread, you need to pull the rooted boot.img and add the verity key from the stock one to it. Also you'll need to add the forceencrypt and verify flag back.
P.S. You also need to re-read the instructions in the decrypt thread. You don't have to rename anything anymore.
Good Afternoon -
OK - sorry to frustrate you, but I think I finally have it figured out. I started from scratch, re-read many posts, and took notes. I was a little confused on the last part so wanted to verify, please...
I've already unpacked the boot.img from the latest HTC A9 (AT&T) RUU and have the two folders. I restored the same RUU to my phone, flashed TWRP 2.8.8.1, backed up the boot.img, and unpacked it before realizing that I should have probably rooted it first.
Correct me if I'm wrong, but here's all I need to do to finish....
1. Download modified A9 boot.img from top of root thread
2. Flash modded boot.img using fastboot
3. Verify TWRP is still installed then use it to install SuperSU 2.67 (latest)
4. Back up boot partition just like I did before in TWRP
5. Unpack it on PC to create ramdisk and split_img folders
6. Copy verity_key from unpack of the actual RUU and overwrite one in rooted unpack
7. Edit the file fstab.qcom in the ramdisk folder of the rooted unpack in Notepad++ and add the "verify" flag after the wait flag on the fist uncommented line - save
8. Repack rooted boot.img
9. Flash phone with repacked boot.img using fastboot
10. Reboot & enjoy a rooted phone + encryption allowing sd internal formatting
Promise not to bug anymore if I can just get this resolved.
Thanks again for your assistance!
UPDATE
Hmm - was just prepping and went to download modded file from root thread's first post. Doesn't seem to have one that matches newest build of RUU I flashed - if I'm interpreting it correctly. Researching further, but if know of alternate method or another solution to get through steps 1 & 2 about (assuming they are correct), I'd appreciate it. Thanks

You don't need anything from that root thread. Everything there is deprecated (which I've said several times).
If you already have the stock boot.img unpacked and ready to go, all you have to do is flash SuperSU, then back up the rooted boot.img that you now have on your device thanks to SuperSU. Unpack that boot.emmc.win and add the verity_key from the stock ramdisk and replace the fstab.qcom with the one from the stock ramdisk. Repack, flash to your device via fastboot or TWRP, and your device will encrypt on that first boot and you'll be good to go.
Just to make sure - you did a Format Data in TWRP prior to flashing SuperSU, correct?

Well, that's the thing... One of the two unpacked boot.img I have currently is wrong. The two I have are:
- One unpacked boot.img extracted from latest RUU using your script in linux
- One unpacked boot.img backed up from unrooted phone which only had TWRP flashed
That was part of my question. I know that the 2nd unpacked boot.img above is worthless as the phone needed to be rooted prior to me backing it up. The question for me is how to flash superSU onto the phone (which currently has the same latest RUU + TWRP 2.8.8.1 installed) if I can only access TWRP is a read-only mode as I'm prompted for password upon booting to recovery. That's why I brought up the legacy root method as I don't know of an alternative... unless SuperSU doesn't require write permissions to whatever TWRP has locked down currently.
Once I can root it, backup it's boot, and unpack it; I just need to literally copy & overwrite the "verity_key" and "fstab.qcom" files (assuming the only difference is the fstab.qcom I'm overwriting doesn't have the verify flag), repack, then flash back to phone via fastboot, right?
Thanks for your patience!

Once you Format Data in TWRP and reboot recovery, you can flash SuperSU and you will be rooted. You just have to back up the boot.img after flashing SuperSU on the unencrypted device to re-enable verity so that adopted storage will work.
P.S. And no, the verify flag isn't the only difference. As I also said earlier (I'm constantly repeating myself), the device must be encrypted for Adopted Storage to work, so the forceencrypt flag from the stock fstab must also be present. That's why it's easier just to replace the whole file. The problem you have at the end of the day is that, while you'll be rooted and be able to use adopted storage in Android, you still won't be able to access said storage (or /data) in TWRP.

Great - Thanks!!
Just to make sure, below's my plan with a small question @ step #5. Does it get your stamp of approval?
Phone (A9) already had latest RUU restored (same RUU I ran against your script to pull boot.img from) and TWRP 2.8.8.1 flashed
1. Boot into TWRP & bypass initial screen prompting for password
2. Format Data
3. Reboot back into TWRP
4. Flash SuperSU 2.76 zip
5. Reboot to system then back to TWRP and backup boot partition? / Stay in TWRP and backup boot partition? / Reboot back into TWRP and backup boot partition?
6. Unpack backed up boot partition from phone
7. Copy "verity_key" & "fstab.qcom" files from ramdisk folder in unpacked RUU boot and paste into & overwrite same files in ramdisk folder of unpacked boot from rooted phone
8. Repack rooted phone boot (which includes both new files)
9. Flash newly packed boot.img to phone using fastboot
10. Enjoy
I really appreciate your help and patience with me!

TWRP can also flash the new image, but fastboot is probably the most reliable way to do it.

Hopefully . . . You'll likely get a reboot on the first boot (possible multiple reboots), as SuperSU needs a reboot to install the necessary files. Since your device will also encrypt on that initial boot, I'm not sure whether there will be a conflict or not.

I proceeded by formatting data, booting directly back intoTWRP, flashing SuperSU, backing up the boot partition, then mounting and copying it over to my PC. The boot.img size was 65,536kb - the same size as the one I unpacked from the RUU. Once unpacked, it was missing the verity_key file and the fstab.qcom file was different + missing the verify flag.
I replaced those two files, then ran repackimg.bat which created image-new.img which I renamed to boot.img. Interesting, though, that this file was only 45,890kb. If it's a repack, shouldn't it be the same or similar? Anyways, the phone was still in TWRP (hadn't booted to system since before the format data) so booted it into bootloader directly and tried flashing boot using my new 45mb boot.img.
If failed - but - my phone was only at 17% power. Don't know if that's why it failed or not so it's charging right now while still in the bootloader. Below is what was echoed when I tried flashing it:
Code:
c:\adb>fastboot flash boot boot.img
target reported max download size of 800000000 bytes
sending 'boot' (45890 KB)...
OKAY [ 3.488s]
writing 'boot'...
(bootloader) HOSD CL#656287
FAILED (remote: 4 RU_BATTERY_LOW please connect charger (17% < 30%))
finished. total time: 4.506s
The reason I didn't boot to system is that I thought that was when the encryption might take place. Going to wait until above 30% power then try flashing again. Powered down to charge, but plan to boot straight back into bootloader to flash. If you see anything that stands out or that I need to do otherwise, please let me know. Otherwise, I'll report back what the result was after getting above 30%.
Thanks again!

The repack is smaller because the backup uses "dd" to copy the entire block device. Not all that space is actually used after compression. That's nothing to worry about.
And these devices are very picky about flashing only when there's sufficient battery, so I'm sure that's the only reason it failed. TWRP, however, doesn't care how much battery you have, so you could always flash the new boot.img in recovery.

Hey, hey, hey - think it worked!!
Once I got above 30%, I flashed without issue. I rebooted and was able to format an sd internally successfully, too. Now, I just need to verify it's rooted, but think it is. Thank you so much for your help! I'm going to write a guide for newbs like me to use in the future soon.
Thanks again!

If your adopted storage doesn't show as corrupted, and you're able to open the SuperSU app in your app drawer and not get a message that no su binary is installed, you should be good to go .

Hello, I buyed my Mate 9 after having a really Bad experience with the Essential Phone. I have no regrets getting this phone but I want root on it.
I have read some threads but all I can find is Oreo related ones.
I would love to have root on my phone, if anyone can point me in the right direction it would be awesome.
I have the MHA-L29 on Android 7.0
BUILD: MHA-L29C567B190
Thanks bros

Thanks mate! I have read everything on that thread! Very helpful guide.
So if I just want root on my phone ( No custom roms or anything) the steps I need is
1. Unlock Bootloader
2. Flash twrp using ADB
3. Flash SuperSu.zip
That's it? I have seen on another thread that I need some Data.zip and other things before flashing it but since the thread you pointed doesn't mention it I belive is not necessary am I correct?
Sorry for the questions mate, I am super new to this phone, I don't want to mess up.

That thread is a little outdated.
Unlock dev options in settings.
Open dev options and enable OEM unlock. (FRP Unlock in fastboot)
Unlock bootloader
Flash either Magisk v15.2 (get from official Magisk thread https://forum.xda-developers.com/apps/magisk/beta-magisk-v13-0-0980cb6-t3618589) or SuperSU 2.82 SR5 (https://mega.nz/#!ZTBQXZra!JHUocH9oMEApULxfLYm9VO5UPhjHNMGLymkXDY_ihhI)
If you want to decrypt (Format data in twrp) you have to flash official SuperSU 2.82 SR5 or Magisk v14. Its not available in later Magisk builds as it breaks support for other devices.
You can edit boot image manually and remove fileencryptioninline.
And TWRP: https://mega.nz/#!9aoASShT!KJkpC_Ll8HZowWF1_fU0olWiHHaeSZuYE3xc3au8EIg (it's a special version I made that enables flashing from /cache and Copy Log button copies to external SD instead of internal. Just make sure you flash this or the twrp from the twrp thread in development)

Hw data zip and public data is only needed when you decrypt. That's because Huawei thought it was a good idea to place theme, wallpaper and update support in /data.
When you decrypt you must format the /data partition, which erases all user data including the hw_init folder. And when that folder is removed you can't set themes or wallpapers and the System Update app disappears. To get them back you need to flash those 2 zips.
The benefit of decrypting is that you can back up the data partition in TWRP. If you use Titanium backup or some other app its not necessary to decrypt.
What do you root for, I've always rooted my phones.

Wow thanks man!
Let me check if I got this right.
I am going to flash Magisk 15.2 ( Downloaded it right now ).
1. I unlock my bootloader from Huawei official page.
2. I Flash twrp-3.0.2-2-hi3660.img using ADB commands.
3. Now that I have TRWP I go and flash Magisk 15.2
Is that right? And that's it? Do I need to decrypt data or is that only needed when I want a factory reset?
Another question is, after I flash Magisk 15.2 ant it's uo and running can I revert back to stock recovery and still have root available?

1. Go to settings - about and tap Build number a few times to unlock Developer options. Go back one step and tap Developer options. Enable OEM Unlock.
2. Request bootloader unlock code (login with your Huawei id)
If you don't have a Huawei id, add it as an account in your phone.
You might have to wait for 14 days after it's added to your phone before you can get code. I could probably unlock it for you if you want to send me your imei, imei2 (if available) and meid (imei, imei2 and meid is available in Settings - About), product id and serial number which can be acquired by typing/pasting *#*#1357946#*#* into dialer. Or there are paid services that does it too.
(send in pm if you need to send)
3. Flash twrp 3.1.1 from either https://forum.xda-developers.com/mate-9/development/recovery-unofficial-twrp-huawei-mate-9-t3515617 or https://mega.nz/#!9aoASShT!KJkpC_Ll8HZowWF1_fU0olWiHHaeSZuYE3xc3au8EIg
4. Flash magisk.
Decrypt is just if you want to backup /data in twrp, no other reason.
And yes, you can flash back stock recovery.
Download your stock firmware from http://pro-teammt.ru/firmware-database/ (search for MHA-L29C567B190)
If you just need to extract recovery or boot select a OTA-MF as they're smaller in size (500mb compared to 2gb+ for full firmware).
Download Huawei Update Extractor and extract.
Extract update.app from the firmware zip.
Open Huawei Update Extractor. Click on the '...' button and open the firmware update.app.
Right click on Recovery and click on extract selected.
Now put phone in fastboot and flash recovery.img (fastboot flash recovery recovery.img).
Now you have stock recovery.

Kk will do, thanks for your help
Thanks guys! Rooted perfectly and using my Rooted apps on the Mate 9!
DISCLAIMER: I'm not responsible for anything that happens to your device. Use the steps below at your own risk . Be mindful of the facts unlocking bootloader voids your warranty and also hard resets your device - ALL YOUR DATA, SETTINGS, FILES AND APPS WILL BE DELETED. Rooting your device voids warranty as well. I own the Chinese SHT-AL09 8.4" LTE device and tested this root procedure ONLY WITH THIS MODEL. However, I believe there is a good chance the steps below will work for all other models of MediaPad M5, including WiFi only variants and 10" models. You MUST unlock your bootloader first. Do NOT use ramdisk image I provide in the steps below for any other model besides SHT-AL09 - doing so is guaranteed to render your device unusable. Ramdisk I provided is ONLY for SHT-AL09. You will need to extract your own ramdisk from stock firmware, specific to your device model
Credits:
@Wirmpolter - this root method largely based on his Magisk guide for Mate 9
@topjohnwu for creating the awesome Magisk Manager, which was used to patch ramdisk image with superuser binary
People, who created HuaweiUpdateExtractor
@magnumlove who pointed me in the right for developing root method in this post
This site, for hosting stock firmware for Huawei MediaPad M5
1. First, you will need to unlock the bootloader of your M5. Follow this guide
2. Transfer this patched ramdisk image to your device
Note for users with version of M5 other than SHT-AL09: Do NOT use the above ramdisk image. Download the full stock rom (update.zip) from the site I linked in the credits. Extract UPDATE.APP file from the zip. Then use HuaweiUpdateExtractor to extract ramdisk.img specific to your device. If you get errors in HuaweiUpdateExtractor - uncheck first 2 checkboxes for checksum verification on Settings tab and try again
3. Once bootloader is unlocked, install latest Magisk Manager from the official Magisk thread
4. Once Magisk Manager gives you a pop-up prompt to either download Magisk zip or patch the boot image file - chose to patch the boot image, but instead of boot.img select ramdisk.img from step 2. Magisk Manager should give you a message the image was successfully patched. It will be saved as patched_boot.img in MagiskManager folder on your sdcard. If it does not say success - do NOT proceed
5. Transfer the newly created patched_boot.img back to your PC
6. If you already have ADB and Fastboot tools installed on your PC you can just use what you've got. If not - get them from here
7. Connect your M5 to PC via USB cable
8. Run command prompt. If your ADB and Fastboot are installed as system app - you can do this from any path in CMD. If not - you need to switch in CMD to your ADB and Fastboot folder. Either way, the patched ramdisk patched_boot.img file must be in the same path, from which you will be running commands below in CMD window
9. Type "adb " in CMD window to start android debug bridge
10. Type "adb reboot-bootloader" and wait until your device restarts in Download mode
11. Once in Download mode, type "fastboot flash ramdisk patched_boot.img" - you should see some output from flash procedure, indicating successful flash
12. Once patched ramdisk is flashed, type "fastboot reboot"
That is it - you're done. Once your device reboots it will be rooted.
Note 1: Magisk Manager has it's own built-in superuser app and uses Systemless root, which works completely differently - you will not see external, standalone app like SuperSU or SU you might be familiar with in your App Drawer. The way to control the superuser app is from Magisk Manager itself: Settings->Superuser section
Note 2: I don't do tech support via PM, so don't PM me for help or with questions. Use the thread instead, and some other XDA members or myself will probably help you. Good luck!
Note 3: You may find some links to Huawei stock firmware in the 2nd post
UPDATE - August 6, 2018
Huawei officially approved 8.0.0.171 firmware with GPU Turbo for installation on SHT-AL09 devices. If you're doing first time root - just follow the original steps above. If you are already rooted and want to upgrade to 8.0.0.171 - follow the steps below:
1. Boot into download mode:
Code:
adb reboot-bootloader
from CMD window
2. Flash stock recovery from 8.0.0.171 to your device in fastboot:
Code:
fastboot flash recovery_ramdisk recovery_ramdis.img
3. Download and install the official OTA through Settings (full or just the update)
4. Boot into download mode again and flash patched ramdisk from 8.0.0.171
Code:
fastboot flash ramdisk patched_boot.img
5. OPTIONAL: If you were using TWRP or any custom recovery - you will need to reflash it back
Code:
fastboot flash recovery_ramdisk twrp.img
or whatever you named your custom recovery image
REMINDER: Do NOT use ramdisk image I provided for any other model besides SHT-AL09 - doing so is guaranteed to render your device unusable. This patched ramdisk is ONLY for SHT-AL09. You will need to extract your own ramdisk from stock firmware, specific to your device model
Needless to say, all the images you are going to flash must reside in the same directory, from which you are going to be running the CMD commands. If your ADB/Fastboot folder is not in your WIndows' PATH environmental variable - the images must be placed in the same folder where ADB/Fastboot binaries are, and CMD commands must be run from that folder.

I'm considering buying an SHT-W09 with firmware version 8.0.0.200 (C567), but I'd like to know if I can root it first. I do not know if the bootloader has been unlocked. Since you have the same version, can you confirm that it's possible to unlock and root, and if so, sketch out how it's done? I'm confused about whether it's possible with this firmware.

Unlocking is possible *only* if you've gotten already your unlock code. As this service was suspended about 2 years ago there is no easy way to get it unlocked.
Small request to developers, or people with access to reliable file hosting: I don't have a developer account, so all the files I linked or referenced in the OP are hosted on free hosting sites. That file hosting has expiration date and max downloads limit, so the files will become inaccessible sooner rather than later. Please upload these files to reliable hosting and create a post with the links. I will link your post in the OP as a mirror.
In the meantime, mirror for SHT-W09 firmware: https://mega.nz/#!asVjmZrR!bW2OmXgTjnyVN4pqb9fA7OzAJ4bzil7YZxNW14qoCmk
I can confirm that this works on the 10.8" wifi model using the devices relevant ramdisk.img.
Hello, can somebody test sixaxis controller tool with root and magisk? There is a Trial in Google Play Store, that is called sixaxis compatibility checker without purchise the App. Maybe i want to buy the Tablet, but only with Dualshock 4 Support...
Just a heads up, been following threads on this forum for flashing a GSI. Now that you guys can root, you can also make backups of your own stock system image if you can't find one from Firmware Finder. Then you can safely try flashing the GSI.
@MishaalRahman well it's bit like chicken egg dilemma. As we do not have a stock system image for e.g. SHT-W09 we cannot patch the ramdisk.img and so we cannot get the stock system image ...
Thanks Apo11on, great to have root so soon for the M5! Do you know if there's a way to get Xposed working? I tried the Xposed Framework SDK 26 from inside Magisk, but it put me in a boot loop.
Question is, for those of us with the Non Pro version, can this still be done.
@OHP Yes. The OP did it with the 8.4" version which has no pro option.
I'm looking to buy the Chinese 10" wifi version myself but need Google Play Store + Services on it which I'm guessing the Chinese version doesn't have. Is one of the firmwares at the website you link to a global version of the firmware that will work on this model?

Doesn't matter what version you have as long as you have access to your device firmware and the ramdisk.img. You really need to reread the guide.

I have exactly the same tablet/firmware as you and it was fine. The additional letter also threw me a little. But if you are unsure, download Huawei Firmware Finder from Google play and it will automatically detect your tablets firmware (which you can download if you wish).

2. Transfer this patched ramdisk image to your device
Note for users with version of M5 other than SHT-AL09: Do NOT use the above ramdisk image. Download the full stock rom (update.zip) from the site I linked in the credits. Extract UPDATE.APP file from the zip. Then use HuaweiUpdateExtractor to extract ramdisk.img specific to your device. If you get errors in HuaweiUpdateExtractor - uncheck first 2 checkboxes for checksum verification on Settings tab and try again
I have a CMR-W09 :s i can got the files downloaded and the huwai software not sure how i make a img
The good news is I followed these instructions yesterday and they worked perfectly (SHT-AL09).
The bad news is, I seem to have lost root overnight.
---------- Post added at 06:41 AM ---------- Previous post was at 06:22 AM ----------
And I figured out why I lost root; I was playing around with Developer options and switched the default GPU renderer from 'default' to 'Skia.' Apparently, this disables root access until you switch back. I regained root access on a reboot, lost it again after switching back to Skia, and then regained it after switching back to default.
I got the right image file from the site and huwai extract. I have googled how to use this app but what files do I extract as there appears to be. Alot ? I extracted all of them ? I don't have a ramdisk.img
Also thanks for writting this up. Without it I would be lost
Thanks for the efforts making this thread. Unfortunately my device is SHT-W09 and I'm still waiting for the right firmware. Is there anything I can help, considering I have the device?
@dkk6 I am in the same boat as you. Unfortunately I installed the update to 8.0.0 123 without having the Firmware Finder installed on the device. Do you have installed already the update to 8.0.0 123?
If not, you could install Firmware Finder and provide us with the ota url ...
This works perfectly no issues. i had some how maanged to download the wrong rom first. AND thankfully it did not have a ramdisk in. it is important that your firmware matches the firmware present on the site as explained. This was easy guide to follow now to flash it with somthing other then andriod

I'm on 8.0.0.101
Hey there,
I am currently struggeling with my Samsung Galaxy S7 (Exynos) device, running on superman rom (Android 8).
What happened?
For root I´m using Magisk Manager and for banking apps I have Magisk hide running. Then the program told me that there is an update (Magisk App) available. So, as always and recommended, I choosed "Direct Install" but that failed for some reason. OK I thought´, no problem. Later I wanted to reboot my phone but it didn´t. The screen says "Downloading.... Do not turn off device!". I only can enter "Download Mode" and "Recovery Mode via TWRP".
What I tried so far:
1) Wipe cache/dalvik --> not successful
2) Tried to do a factory reset via twrp --> not successful
3) Tried to flash BL via Odin --> not successful
At this time I realised that the same problem occured to my Galaxy Tablet SM-T580. So I came to the point that I did something wrong with updating magisk on both devides.
What I also tried next:
4) Tried to delete magisk modules via twrp --> not successful
5) Tried to uninstall magisk through twrp by downloading the latest Magisk app and rename it to "uninstall.zip" as recommended in installation guide --> Not successful because of Error installing zip file: Unsupported /Unknown image format (unpacking image format)
What can I do next?
Can anyone please help me, since I have two bricked devices now????
A simple kernel flashing would fix the problem, extract the original boot.img of your current ROM, and flash it via TWRP.
Cause it is clearly a problem with your boot.img, if that didn't work (I'm sure it will), then just dirty flash your current ROM.
P.S. If you are encrypted, you might encounter an error doing a simple factory reset, you'll have to format the whole data partition.
Hi @Mohamedkam000,
many thanks for your help. After hours of browsing the web and trying various methods I was able to get my 2nd device (Samsung Galaxy Tab A from 2016) back to life.
What I did: I installed the latest samsung mobile phone drivers on my PC then I connected the tablet to it. I was able to access the internal memory and in the folder "data" Magisk put a backup of the original boot.img. So I installed this "boot.img" via TWRP and voila.......everything works fine again
I´m very happy now.
But unfortunately this method didn´t work with my Samsung Galaxy S7. I just couldn´t find any boot.img file on the phone.

P.S. If you are encrypted, you might encounter an error doing a simple factory reset, you'll have to format the whole data partition.

Hi @Mohamedkam000,
many thanks for your help. After hours of browsing the web and trying various methods I was able to get my 2nd device (Samsung Galaxy Tab A from 2016) back to life.
What I did: I installed the latest samsung mobile phone drivers on my PC then I connected the tablet to it. I was able to access the internal memory and in the folder "data" Magisk put a backup of the original boot.img. So I installed this "boot.img" via TWRP and voila.......everything works fine again
I´m very happy now.
But unfortunately this method didn´t work with my Samsung Galaxy S7. I just couldn´t find any boot.img file on the phone.

Glad your tablet revived again.
Magisk creates a backup of the boot.img found just before flashing magisk, it is compressed in gzip format, so you need to pull it, extract it, and push it back to the phone, then flash it.
The file is usually in /data/stock_boot_${SHA1}.img.gz
You can extract it using the built-in terminal of TWRP, if PC is not accessible at the moment by writing and executing the following command:
gunzip {stock-boot-name}.gz
Replace {stock-boot-name} with your backed-up boot name (without the curleybrackets), or you can use the following command:
gunzip *.gz
That'll extract the gzip archive, and the boot.img will be in /data of which you can navigate to it and flash it.
There's another guaranteed method, if you have the file of the ROM you're using right now, you can just open it (it's just a zip archive) and search for the boot.img of your specific phone model and flash it.
Another guaranteed method will be by flashing a custom kernel compatible with your current ROM, like Moro AiO kernel, of which has a wide support for ROMs starting from Oreo, and up to Q, AOSP, or stock-based, just in one file.
Moro's thread: Moro Kernel
you can't access kernel backup because TWRP does not support encryption and Magisk Manager might removed encryption in boot

Doesn't seem like he's encrypted, he found the boot backup of his tablet in /data so he has probably searched for a similar file on his S7, but since it is compressed, he won't find it solely.
Also he would've told us that his /data is empty or something.
start from scratch with older magisk, current 22 has bug

Thank you for your help.
I had a n old twrp backup on another external hard drive. I extracted the boot file and repached it with 7zip to boot.img and flashed through twrp. That also didn´t work for various times. TWRP always said "failed".
In the end I didn´t manage it to bring my phone back to live. Anyway, I decided to flash the latest LineageOS (Android 11) and now its running smooth again.
Thanks again.
Try using sp flash tools flashing the boot.img
