[GUIDE] Unlock Bootloader, Root, Install TWRP & Decrypt

For an easy way to Unlock, Root & Decrypt your Mate 8 here are the steps you need to take. This has been requested by a number of you so here it goes:
1) Unlock your bootloader. There are three steps you can take. The first is free. The second method requires you to pay a few dollars but it works and is the fastest way. I would highly recommended this method. This is confirmed working on all models.
Option 1: Make a Huawei ID on your phone and stay signed in for 14 days and go then online to unlock your bootloader and it should work on the website.
https://uniportal.huawei.com/accounts/register.do?method=toRegister
Option 2: If you want to unlock your phone immediately and don't mind paying a few dollars this method works. Visit here:
https://www.dc-unlocker.com/buy
- Download the DC Unlocker Software
- On their site buy 4 credits. I used PayPal. It cost me around $4.38 USD.
- Follow the instructions in their tutorial. Choose "Read Bootloader Code" in DC-Unlocker to get your bootloader code. It was pretty easy.
- Put your phone in bootloader mode (plug into the computer and hold in power and volume down with the phone off) and download the Android tools from the link at the end of step two. Extract them to a folder on your desktop and open a command prompt to that folder and type in fastboot oem unlock xxxxxxxxxxxxxxxx where x is your bootloader unlock code the DC Unlocker program gave you.
2) Download the TWRP recovery of the EMUI version you are currently on (5.0 ,5.1, 6.0) from here:
https://drive.google.com/drive/folders/0B5I_q70mNuR4Vmo5LUUyU2t5TWs?usp=sharing
Then put your phone into Bootloader Mode (plug phone into computer and hold in power + vol down) and fastboot flash the TWRP recovery file you downloaded. Here are the Android tools you need to fastboot flash. Extract them to a folder and put the twrp recovery img file inside the folder as well and open up a command prompt to the folder and type in fastboot flash recovery TWRP-ENG-XXX.img (where XXX is the version of TWRP you downloaded) Then type in fastboot reboot. When your phone reboots shut it back down and then hold in volume up and power until it turns on and keep holding in volume up until the phone boots into TWRP recovery.
https://drive.google.com/file/d/0B5I_q70mNuR4UzdkeERRZExnUVk/view?usp=sharing
3) Root your phone.
In TWRP flash SuperSU:
https://drive.google.com/file/d/0B5I_q70mNuR4OWlXeTJuTjdoS0k/view?usp=sharing
After flashing you will be rooted and on TWRP successfully.
4) Decrypt your internal storage.
You must decrypt your internal storage so TWRP can see it or if you want to be able to flash a rom. If you're getting an unable to format data in TWRP then you know you need to do this. Boot into TWRP then go to Wipe then Advanced Wipe then Format Data and type in yes. This will wipe and decrypt your internal storage. BACK UP YOUR INTERNAL STORAGE before you do this if you have anything important on it. (Pics are at the bottom of this post) Then either flash one of my roms or decrypted boot.img to keep the internal storage decrypted. If you boot with the stock boot.img installed it will encrypt your internal storage again and you'll have to repeat the process.
*To take an ota or do the dload method you don't have to relock"

does flashing supersu through twrp directly work? in my case i needed to flash the decrypted boot image first, otherwise id have a bootloop after rooting...

It works for me when i'm on stock B137.

good stuff, maybe it was because of a different supersu version which phone do u have? AL10 or L29?

I believe so. I'm not too familiar with the International firmware. I saw it posted somewhere so I saved it in case anyone needed it.

yep thats correct, B137 latest chinese and B133 latest international rom
thanks for the info, i had some problems with flashing supersu, but once i flashed the decrypted boot image my bootloop and partition mounting troubles in twrp were gone no idea what exactly was the culprit there but i guess ill stick to flashing the decrypted boot.img first before continuing with rooting a firmware...

I made it two days ago and it works with mate8.

Does this now mean we are likely to see numerous custom roms & kernels being developed in the very near future for this awesome smartphone ?

i sure hope so especially since huawei seems to have publicized its kernel source for the mate 8 just recently in the end it depends on the interest of the devs, though, and the overall popularity of the mate 8! im staying optimistic that itll be better than with the mate 7

Don't worry, it works with the Mate 8. You're doing something wrong if it didn't work.

Say we do unlock BL and then root... Than I guess we cannot get OTA updates right? Also does the BL re-lock?

You should still get ota updates if you're unlocked and rooted. Yes you can relock just make sure you fastboot flash or do the dload method to get back to stock before you relock.

it's the code in first line, cofusing

[Info] Unlock Bootloader, Recovery, ROOT [Noob friendly]

Hi guys I get this phone from not much time so i decide open this thread for explain the basic and necessary
1. How to unlock bootloader?
As all know Huawei web page for get unlock code not is working an also email assistance so how you can get the code,
well follow this:
- You must stay in a firmware less of 4.4.2 or 5.1.1 not 6.0 in my case I use this firmware "MT7-TL10C900B326" *If you're in 6.0, so must downgrade.
- Then to install or stay in a 4.4.2 or 5.1.1 base, download and install Kingroot (Phone will said u that could damage your phone but install it, no problem with it)
- Now open Kingroot and follow the instructions for root your device
- When all has sucessfull now install HonorTurner that can get in this thread --> http://forum.xda-developers.com/mate-7/general/unlock-code-via-honortuner-t3217651
- After to install grant the root access permission and go to this tab " Hardware Info" and look this line "WVLOCK" (This is our unlock code, so copy the code in a secure place)
- Now go to "Developer Options" If dont have enabled go to about phone info and press sometimes "Build Number", and enable "USB debugging and allow all and be sure that have installed huawei suite in your pc for get the drivers installed
- Now download the "SRK Tool" from this thread --> http://forum.xda-developers.com/mate-7/development/tool-srk-tool-huawei-beta-02-20160501-t3369990
- After to download connect your phone to your PC, dont press nothing in the usb options, only connect
- Now run the SRK Tool and press 1. Unlock bootloader, will ask if you have your unlock code (that we get it with HonorTurner) so press Y, and will start the adb service and will ask for our code, after to add the code, the phone will reboot automatically and u can go to fastmode and look that your device know is unlocked
2. How to install recovery?
* If want install MM before of all u can do it, only be sure that have your bootloader unlocked
* For enter to bootloader mode press Vol + then Vol - and Power at the same time with the phone turn off
- Donwload latest recovery for your variant, in my case M7-TL10 (You can found it here --> http://forum.xda-developers.com/mate-7/general/huawei-mt7-l09-l10-stock-firmware-ota-t3275784)
- For M7-TL10 download this --> https://mega.nz/#!9kBWnY7T!ybhARn5UNXAyxrdQZ1ytKks24eCyzxkgdVhEza6zwFQ
- Connect your phone and be sure that have enabled USB Debugging option and have unlocked the bootloader
- Run the tool and select the recovery that want install
- Wait that the tool finish to install and will reboot automatically, and enjoy!
NOTE--> For enter to recovery mode press Vol + and Power at the same time with the phone turn off
3. How to root your phone?
For 4.4.2 and 5.1.1
- Download and install KingRoot from this link: http://king.myapp.com/myapp/kdown/img/RushRoot-CafeUser-release-nolog-sdk-lc64E08B246F910AF4-b220-svn372160-201609012210b_protected_signed.apk *(Phone will said u that could damage your phone but install it, no problem with it)
- Now open Kingroot and follow the instructions for root your device and wait
- And your phone will be rooted!!
For 6.0
- Download and install a custom recovery *Is necessary unlock your bootloader for it
- Download SuperSU with/without apk from here --> https://www.androidfilehost.com/?fid=313042859668276376 or https://www.androidfilehost.com/?fid=313042859668276377 and copy to your phone, if both zip dont work so use this one https://www.androidfilehost.com/?fid=601296195406528565
- Go to recovery mode (Turn off the phone and press Vol + and Power at the same time of 5-7 seconds)
- Now search and install zip "SuperSU-vX.XX.zip" and wait that the installation finish
- Reboot and enjoy of your rooted phone in MM
I do this thread and guides in 1 place because I see that some info in the others threads are wrong or one in place and other in other place, so for this I decide do it, If any want another guide let me know and I'll add it in this thread, so enjoy of your Mate 7!

Updating guide

Hello friend. Sorry I write you here but it seems that you are good in rooting and I need some help as I am really desperate since I can't backup, and use the apps I need without root access. I always have been rooted in any phone but since I received an OTA update, around 1 giga , giving me the Version Android 6.0 on my phone MT7-TL10C00B561 (Chinese) I lost root.
I tried some guides for uncloking the bootloader but I get the msg like it has not been used for 14days or smth like this.
Can you(or someone) please help me as this phone is out since 1 and half year and I still can't get the root.
Thank you in advance.

just downgraded to B358 and i just lost ALL my important Data, photos, screenshoots (very important) , app datas , configurations ,,,,ALL !! I did not expected to loose the data...as i did not lost any data when i upgraded... but also i could not do any backup as i was not rooted so i could not save the app data etc... I am really sad !
Just hate this phone! Will try unlock bootloader and see if i can get root and update to MM.

So, by your guide i rooted with KingOroot the Lolipop.
Than the Phone got some updates by OTA and now i have the version B561 (all the log is in chinese)
So now i dont have the Root anymore.
I tried the recovery you have uploaded over, twrp 3.0 but when i enter recovery it does not askes me to update but only : reboot, wipe/reset , cache . (with emui logo)
so i guess i still dont have a costum recovery ?
How can i Root it with supersu if i cant choose the zip file with the supersu ?
doubt, and sorry for the silly questions :
- what is the better firmware? the asian version or the european ?
wich one should i use?
and, what about the ota updaes. how can i get them ? do i have to put the huawei recovery again after the root so i can get them ? right ?
and do the same procedure : update- installing costum recovery - root again and install again the huawei recovery ?
thank you !
waiting to root the MM as i have now unlocked bootloader.

Hi,
It seems it didnt install. Perhaps try again? Did you run the tool mentioned in the OP?
I'm not sure what the difference is between asian and european firmwares. I've jumped between middle-east and european roms, and didnt notice much difference.
If you are rooted, and you want OTA updates, you need to first un-root (can be done in the SuperSU app) and install huawei recovery, then you will receive updates.
Then you can just re-flash TWRP and SuperSU, and you are rooted again.

Use the same unlock code you've used before, get it again.
And why are you using that build B300, you could have at leasT tried B336, which in my opinion isn't having any problems noticeable, battery drain also good...people complain about this, but if you know what you're doing this will never be an issue.

Thanks for the response, I'll try tomorrow, i've already forgotten and deleted the code. Actually, it's all misunderstanding on why i flashed this build lol. I am planning to revert to MM stock and i'm still looking for some guide on how to. I tried other methods and didn't get luck. If you have any ideas would you mind helping me again? Thanks!

This method don't require unlocked bootloader, don't require TWRP.
Just get the rollback file and full MM update file.
Install rollback first then MM file after, put the extracted update.app files In the dload folder on root of sdcard, one by one after each install
Or
If you don't want to use rollback file, unlock bootloader, then flash patched oeminfo file via:
1.fastboot using this command: fastboot flash oeminfo xxx (xxx= name of oemifo zip you have, ie. fastboot flash oeminfo C432oeminfoDual.zip)
Or
2.while In fastboot flash revolution nougat recovery, then boot into it by "vol up + power" then flash the patched oeminfo,
Then once flashed OEMINFO then install via 3 buttons mode the update.app of your firmware, this must be in dload folder on sdcard as above.if asked for password then use "reset"

Edit title to solved.
The current TWRP by Revolution for nougat can't mount /data partition, and if you need flash anything there, you've got to change filesystem as advised In the tutorials, but you can flash mods or apps to system partition without problems....this problem is In nougat TWRP only currently, MM TWRP has no issues at all...anyways good to hear your sorted!

How to unroot and get locked bootloader again

Hi, I rooted my tablet about 2 months ago - Now I have root and TWRP. Now I need to remove root and put a stock image with locked bootloader.
Do you think I can do it by my own? (for example, with fastboot?)
Many thanks

Hi,
You can achieve this by following methods.
Method 1
Since you have TWRP
you can flash the stock firmware from TWRP and it should lock the bootloader, unroot and then overwrite the twrp with stock recovery.
What you need?
For this method you need the stock firmware zip files and firmware finder app from google store.
Method 2 (risky, not recommended)
Download SRK tools by somboons
From here https://forum.xda-developers.com/showpost.php?p=66627615&postcount=2
Unzip the file
Open the application
Then on the main screen, you will have plenty of options to type 1, 2, 3, etc..
Just type 000 to enter the command prompt here.
Once you are in that command prompt you can type the adb commands.
to lock the bootloader you need to type
fastboot oem relock xxxxxxx (just check this command. I think
xxxxx is your bootloader unlock code (yes you have to use the unlock code here again)
this will relock the bootloader.
now to unroot
you can just flash stock firmware using dload method.
How?
download the stock firmware
extract the update.app
put this update.app in a dload folder in sdcard.
you have to create this folder on sdcard and name it as dload.
then you can use the code from dialer pad
*#*#2846579#*#*
from there select SDcard upgrade.
It will reboot and flash the stock firmware. You no longer have root. It will also overwrite the twrp recovery with stock recovery.
I would recommend the method 1. It is safe, easy and should complete the desired tasks within no time.
Method 2 has lot of steps and there is risk involved so I cannot recommend this procedure as confidently as the first one.
I have the Huawei Mediapad M3 LTE version and also Huawei Mate 8. There are few similar functions in Huawei devices.
So now the question is where you will find the stock firmware?
You can find the stock firmwares using firmware finder app in google store.
From here -> https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder&hl=en
Install the app.
Open the app
It will automatically find the right firmware's by detecting your tablet model.
All links might not work
So check the one that is working and download that firmware - preferably full firmware.
You will get the zip files if there are two or just one.
then you can follow the method 1.
Hope this works out for you. Hope you find this information useful. :good::good::good:

Hi and many thanks for your kind response!! I tried as you adviced, the problem is that now i have a custom rom and this is the reason, I suppose, for which, every firmware i try to flash, it says "this version is not compatible with the one installed". For what you know, is there a way to flash the firmware without it to check the one already installed?
Thankssss again!!

Hi,
Can you give me more details about your tablet ? It will be in settings - > about device
like
tablet version - is it BTV-DL09 or BTV-DW09?
DL09 is the LTE version
W - is the wifi version
which OS are you running currently?
TWRP version ?
How did you try to flash ? When method did you follow?
I don't know if there is a way to check what you are asking. But we can certainly resolve your issue.
When I was flashing and experimenting on my Huawei Mate 8 last week I came across similar errors. That time I had to dload rollback package from SDcard and then I flashed the EMUI4.1 OS to get back to stock. Now I feel that is the case with your tablet too.
Process is same for both devices. But the files used to flash are different (naturally). That is why I am confident that we can try to come up with a solution.
Point to note
to flash stock rom, the following play a key role.
1) bootlocker - locked
2) recovery - stock
3) Rollback package ( this was really file for Huawei Mate 8, but is it important for Huawei Mediapad M3? I will try to find out).
At the moment, you have custom OS and custom recovery.
so best thing to do is flash the Stock ROM zip files from TWRP. I explained why it is better to do it this way.
Were you able to get the stock rom zip files?
Also please answer all the questions in this post so that I can help you better. :good::good::good::good::good:

It's the LTE version, BTV-DL09
which OS are you running currently?
Android 6.0, EMUI 4,1, Greatslon mod B030
TWRP version ?
Twrp doesn't start anymore and so did root. This happens since yesterday, after installing the custom rom.
How did you try to flash ? When method did you follow?
I installed firmware finder and tried the following firmwares :
BTV-DL09C233B332, 1273 MB, OTA
BTV-DL09C233B035, 173 MB, OTA
BTV-DL09C233B030, 1801 MB, FULL
and always I get the same response : your firmware version is not compatible - upgrade failed.

ok
so your root doesn't seem to work
you don't know if you have custom recovery
you are using EMUI 4.1
1) do the factor reset from the settings > go to -> Settings -> Advanced settings - > backup & reset - > factory data reset
do this - it should take few minutes
2) then -> developer options - > turn on "oem unlock" and " usb debugging " - on
3) please download the srk tools - I think I gave you the link to that software in my previous posts - > please download - extract keep it ready.
4) open the SRK tools - > type 000 in the place where it asks you to type 1 or 2 or 3 .. - you should get command prompt
5) Now press volume down button and hold .. and then connect your tablet to computer ( you have to enter bootloader mode)
6) now we need to lock the bootloader - so run the adb command ( for this you need to put the tablet in bootloader mode )
fastboot oem relock xxxxxxx or fastboot oem lock xxxxxxx
yes you will need the unlock code and in the above command replace the xxxxxx with your unlock code.
lock your bootloader.
7) it will do factory reset - and then your bootloader is locked.
Now at this point you have bootloader locked and you have normal firmware but since you want to go back to stock rom
I am still not clear about the build number. Can you give me the build number ? its in settings - > about tablet - > mine is BTV-DL09C100B006
Model number you and I have the same version. BTV-DL09. But it is the build number which matters.
I checked the firmware finder - unfortunately it is not giving the full firmware - only ota updates.
so the factory reset in the first step above is very very crucial.
The other safe way to get the firmware is through Hisuite
for this you need Hisuite software - you can either go forward to B009 or if it is giving you that option to switch to earlier version then you can go back. But I highly doubt it will give anything. So just try to go forward with B009 ROM.
try all these steps... see if you can succeed to any extent. In the mean time I will try to search for full firmware and if I do I will update this reply or give a new reply.
My name is Sam Hope this works out for you. Don't worry if this doesn't work then we will think about alternatives. But these are very important steps. Good luck. :good::good::good::good::good:

Update: After going through some of the threads on xda I came across one russian website
http://4pda.ru/forum/index.php?showtopic=780572&st=0#entry54523165
you can check the firmwares. They are all custom firmwares. But I am not sure if the version is compatible. check if your tablet buildnumber is BTV-DL09C100B006 or BTV-DL09C233XXX . that is something you need to be careful.
update2 :- http://hwmt.ru/oth/HWFF/info/view.php
this link contains all stock firmwares - but they are all OTA and not Full package.

I have the US version (I believe it is distinguished as BTV-W09C128Bxxx). Using the firmware finder, it appears the only old firmware available for my build is B001_demo and it's only an OTA. If my goal is restore stock recovery, will downloading this and flashing this do anything? I currently have greatslon's TWRP rooted running stock firmware version BTV-W09C128B002. Thanks!

Btv-w09c128xxx

if you check this Russian site
http://hwmt.ru/oth/HWFF/info/view.php
you will find 8 matches for your model.
unfortunately, all are OTA and not full firmware. OTA is good for updating from lower version to higher version. But for downgrading or returning to stock I am not sure. In my experience, I always used the FULL package.
your current situation
1) you have TWRP
2) Rooted ( so bootloader unlocked)
your options
1) Returning to stock seems to be difficult. Only possible way is Hisuite but it won't recognize your device as your tablet is rooted and bootloader unlocked.
To return to stock
a) you need stock recovery ( you will get this once you flash Stock rom in twrp or through erecovery - download stock rom)
b) bootloader locked (this is possible by adb commands using SRK tools )
c) Stock rom (this is the problem - I couldn't find a single site which is hosting FULL stock rom )
d) rollback package ( If there is one, Huawei had it for Huawei mate 8 but for mediapad m3, does it have? I don't know) - I hope this is not mandatory. We should be able to get the job done using a,b,c . previous points.
From my experience, I found that if you have a, b, c you can go back to stock easily.
I saw another Russian site where they have custom roms. But you have to be careful. Check if the version they put out is compatible with yours. You mentioned that your tablet version is BTV-W09C128Bxxx. It looks they have custom roms for BTV-W09C233xxx Can you flash this firmware on your tablet? that is tricky and can be risky too. If any one has done it, then it would be nice if they can share their experience.

The OTA in the firmware finder is not enough to go back to stock. You can try but I am not hopeful because it is not complete firmware and it might get stuck in between or fail.
For now. you can do factory reset from TWRP. That is the only thing that seems possible. Without stock rom or rollback package, it is very difficult to go back to stock. But if you manage to get stock rom for your device. Then flash it in TWRP. Once it completes you will have stock rom installed on your device.
Hope you find this information useful :good::good::good::good:

Thanks for the reply and the useful information. It seems as though I'm out of luck unless I can find a FULL stock firmware package. However, you did mention that I can use Hisuite? Even though I am unlocked, TWRPed, and rooted, Hisuite still does recognize my device (I think it's because I'm on stock rom). When I click on System Recovery it just says "Your device system is running properly and does not need to be recovered." Is there another method I can go through using Hisuite to restore stock recovery?

That's great news.
Good that your tablet was recognized by Hisuite.
For system recovery to work. You have to press volume down and then connect the tablet.
Did you do it this way? I think you did.
Do you have "update" or "restore" option in Hisuite?
If yes when you click on "update" did you get "switch to earlier version" If it gives that then yes you can try but even then we have to keep fingers crossed until it completes the process successfully.
One more thing you can try is using HiCare. But this is for updating to nougat or for OS early adopters.
All the options are coming down to stock rom. If you have one stock rom. Then you can flash it in TWRP or extract the update.app and dload it using 3 finger rule.
Full stock rom - that is the key here. Is it possible for you to get the stock rom for your device? So far I found only OTA's from those Russian sites or custom roms for different models. It will be great if can find all stock firmware's for all the models. It will help many people. Since my tablet was working very well, I didn't think about rooting at all. Mine is BTV-DL09C100B006.
One last option is Unroot your tablet using Supersu app. And then flash boot.img (it is recovery.img not boot.img) from one of the OTA firmwares. that way you can get back to stock firmware. But this is tricky. You have to be very careful about this. If anything goes wrong here then you won't be able to boot into tablet. That is why I cannot recommend this option.
Sorry I made a mistake in this post. It is recovery.img not boot.img. Please be aware.
You can try - Factory reset - from inside the OS or from TWRP. :good::good::good::good:

1) When you say pressing volume down and connecting the tablet, I'm not quite sure what you mean. Do you mean from power off? Anyways, from a power on state, I tried using the Update process within Hisuite and it downloads the B003 firmware, then boots into recovery (TWRP), attempts to flash it, fails, and then I manually have to hit restart system within TWRP.
2) I downloaded an OTA update.zip and could not find a boot.img.
3) Also, what does factory reset from inside the OS or from TWRP do exactly?
Thanks again!

I am sorry. I should have explained it better.
Pressing volume down and holding it for few seconds and then connecting to computer will take you to bootloader mode.
Then you can do the system recovery.
Yes, if you have stock recovery it will go smoothly. You have BTV-W09C128B002. So you need boot.img of the stock firmware belonging to this OS. then you have to flash that using the below adb command
fastboot flash recovery recovery.img
this should get back the stock recovery. Once you have this. You can try the Hisuite again, this time hopefully it should complete the process.
- you have the update.zip - > extract the update.app -> use Huawei update extractor (software in the attachment) -> extract this zip - > run Huawei UpdateExtractor - now open the update.app - > you will be able to see the recovery.img extract it. Flash it using the adb command in SRK tools.
you can download SRK tool from here -> https://forum.xda-developers.com/showpost.php?p=66627615&postcount=2
Open this tool - > type 000 where it is giving you an option to type 1, 2, or 3 etc.. you will get command prompt . there you have to type the fastboot command to flash the boot.img.
But once again. Just want you to know this process is risky. Wrong file or if anything goes wrong you won't be able to boot into your device. So please be careful. It is risky. Please do not proceed with these steps. Flashing the stock rom is the right way. Or Hisuite. Those are safe methods. But not this.
Factory reset from inside the OS means - > go to settings - > advanced systems -> backup & reset -> factory data reset
that will do the factory reset on your device.
or
since you have TWRP. you can boot into TWRP - go to wipe - > there you will have factory reset. you can do it that way too.
I apologize for not explaining properly. I am sorry I made a mistake. It is recovery.img not boot.img.
Hope you found this information useful. :good::good::good::good::good:

Hi Sam!
unfortunately the custom rom I put 2 days ago hiddens the build numer (it says "B030 greatslon mod") but I annotated the previous one, which was the one you said "BTV-DL09C100B006".
Now I'm at work but this evening I'll try to do what you adviced. Thanks again and have a good day

Yes, I continue to find your information very useful!
I have downloaded the Huawei Extractor and was able to use it to extract boot.img, fastboot.img, and recovery.img. However, this is for B003 and I am currently on B002. B002 does not appear to be available through the links you previously provided (neither OTA nor Full). Using B003 extracted files, what would be the proper sequence of flashing? Should I install the B003 boot.img first, hope that it boots into fastboot, and then flash B003 recovery.img in fastboot mode? How do I even go about installing B003 boot.img? Through SRK tools or adb? Or is this all too risky, and I should not even bother with B003 OTA files while I am still on B002?
Thanks again!

Hi Sam!!
I recovered my huawei unlock code and tried to relock the tablet, after having resetted it to factory (remember I still have custom rom).
After putting the tablet in bootloader mode and typing the following command on sk tools:
fastboot oem relock xxxxxxxxxxxxxxxxx (my unlock code)
I get:
....
FAILED (remote: stat not match)
finished. total time: 0.00 secs
I also tried "fastboot oem lock xxxxx" but it says "command not allowed".
Do you have ideas? I am blocked there...
Thanks!!

Hi,
You can achieve this by following methods.
Method 1
Since you have TWRP
you can flash the stock firmware from TWRP and it should lock the bootloader, unroot and then overwrite the twrp with stock recovery.
What you need?
For this method you need the stock firmware zip files and firmware finder app from google store.
Method 2 (risky, not recommended)
Download SRK tools by somboons
From here https://forum.xda-developers.com/showpost.php?p=66627615&postcount=2
Unzip the file
Open the application
Then on the main screen, you will have plenty of options to type 1, 2, 3, etc..
Just type 000 to enter the command prompt here.
Once you are in that command prompt you can type the adb commands.
to lock the bootloader you need to type
fastboot oem relock xxxxxxx (just check this command. I think
xxxxx is your bootloader unlock code (yes you have to use the unlock code here again)
this will relock the bootloader.
now to unroot
you can just flash stock firmware using dload method.
How?
download the stock firmware
extract the update.app
put this update.app in a dload folder in sdcard.
you have to create this folder on sdcard and name it as dload.
then you can use the code from dialer pad
*#*#2846579#*#*
from there select SDcard upgrade.
It will reboot and flash the stock firmware. You no longer have root. It will also overwrite the twrp recovery with stock recovery.
I would recommend the method 1. It is safe, easy and should complete the desired tasks within no time.
Method 2 has lot of steps and there is risk involved so I cannot recommend this procedure as confidently as the first one.
I have the Huawei Mediapad M3 LTE version and also Huawei Mate 8. There are few similar functions in Huawei devices.
So now the question is where you will find the stock firmware?
You can find the stock firmwares using firmware finder app in google store.
From here -> https://play.google.com/store/apps/details?id=com.teammt.gmanrainy.huaweifirmwarefinder&hl=en
Install the app.
Open the app
It will automatically find the right firmware's by detecting your tablet model.
All links might not work
So check the one that is working and download that firmware - preferably full firmware.
You will get the zip files if there are two or just one.
then you can follow the method 1.
Hope this works out for you. Hope you find this information useful. :good::good::good:

you can check the firmwares. They are all custom firmwares. But I am not sure if the version is compatible. check if your tablet buildnumber is BTV-DL09C100B006 or BTV-DL09C233XXX . that is something you need to be careful.
update2 :- http://hwmt.ru/oth/HWFF/info/view.php
this link contains all stock firmwares - but they are all OTA and not Full package.

Yes, I continue to find your information very useful!
I have downloaded the Huawei Extractor and was able to use it to extract boot.img, fastboot.img, and recovery.img. However, this is for B003 and I am currently on B002. B002 does not appear to be available through the links you previously provided (neither OTA nor Full). Using B003 extracted files, what would be the proper sequence of flashing? Should I install the B003 boot.img first, hope that it boots into fastboot, and then flash B003 recovery.img in fastboot mode? How do I even go about installing B003 boot.img? Through SRK tools or adb? Or is this all too risky, and I should not even bother with B003 OTA files while I am still on B002?
Thanks again!

Yes it is very risky. Please proceed with caution or don't do it at all as these steps are risky and can turn your tablet into brick. I say this because we are not getting the right set of files to test properly. We don't have the rollback package or stock ROM so the situation is precarious. If anything goes wrong, it would only increase your problems. For going back to Stock all you need is Stock Recovery & Stock ROM and unroot.
You are in stock rom but rooted. You just need to flash the right recovery.img file using SRK tools. Please check my previous posts on how to run adb commands using SRK tools. You have to do this in bootloader mode. Fastboot or bootloader mode are one the same. You need only recovery.img and that should be flashed in fastboot or bootloader mode. Check the Russian site http://hwmt.ru/oth/HWFF/info/view.php this has B003 firmware
For the moment it appears like there is only one way forward if nothing else work for you. I hope you have seen the Greatslon ROM files in the other threads. You can download his EMUI 5.0 it looks gr8 and seems to be stable from what I read. He has uploaded all the required files for his ROM. Have a look and see if it interests you.

Hi Sam!
unfortunately the custom rom I put 2 days ago hiddens the build numer (it says "B030 greatslon mod") but I annotated the previous one, which was the one you said "BTV-DL09C100B006".
Now I'm at work but this evening I'll try to do what you adviced. Thanks again and have a good day

You and I have same tablet version. I bought my tablet on Amazon.de. Please make a note of your steps and how your tablet responded. Based on that we can see how to move forward. It will be really helpful to know your experience.
To both of you @danibyte27 and @asianpianoman
Please be careful while handling these .img files or any system files. Flashing wrong files or any mistakes or errors during flashing can be detrimental for your tablets. There is huge amount of risk. So please proceed with extreme caution. Do not proceed if you have doubts. Please do not hesitate to ask if you are in doubt.
It appears that Greatslon - Android Nougat ROM seems to be the best way forward. As you have seen FULL Rom is not available anywhere. So that complicates things. Going back to stock ROM seems to be very tricky for now until we get the right Stock ROM and other important files.

Hi Sam!!
I recovered my huawei unlock code and tried to relock the tablet, after having resetted it to factory (remember I still have custom rom).
After putting the tablet in bootloader mode and typing the following command on sk tools:
fastboot oem relock xxxxxxxxxxxxxxxxx (my unlock code)
I get:
....
FAILED (remote: stat not match)
finished. total time: 0.00 secs
I also tried "fastboot oem lock xxxxx" but it says "command not allowed".
Do you have ideas? I am blocked there...
Thanks!!

Did you put the oem unlocking - ON & usb debugging on ?
1) check the bootloader - take a photo and see if it is showing phone locked or unlocked
hold volume down on your tablet for 3 seconds and then connect to computer
update : Can you check if your unlock code is correct?. it says "stat not matched" please check the unlock code.
risky steps
[[[try fastboot oem unlock xxxxxxx even if it says your phone is unlocked. ]]]
[[[then fastboot oem relock xxxxxxxx]]]
if this doesn't work
then flash the recovery of your current firmware using
use SRK tools - go to command prompt - type the below command ( this recovery.img should be in SRK folder )
fastboot flash recovery recovery.img
I would suggest you not to go back to stock. Please try to move forward to greatslon EMUI 5.0 ROM.
https://forum.xda-developers.com/mediapad-m3/development/twrp-greatslon-mod-t3489232
Please check this link https://androidfilehost.com/?w=files&flid=125388 he has uploaded all the files.

Hi Sam,
I think I'll follow your advice and don't try to install stock image until I find a clean and reliable solution
Could you please link me the address to download Greatslon nougat rom? I can only find 6.0 greatslon rom here:

It appears he didn't upload the EMUI 5 ROM for BTV-DL09C100 in that link.
However, he uploaded EMUI 5.0 on this Russian forum
http://4pda.ru/forum/index.php?showtopic=780572
But those seem to be for C233 and other versions.
So I think it is better to check with him on the other thread https://forum.xda-developers.com/mediapad-m3/development/twrp-greatslon-mod-t3489232 and see if it is ok to install C233 on C100. It is his work so I feel he is in best position to answer this question . :good::good::good::good::good:

Good news!!! Stock ROM link

Hi,
Hope you remember me.
Finally I have some good news for you.
Some wonderful person found the link to download the Stock ROM & Rollback package in another thread.
here is the link
http://consumer.huawei.com/it/support/search/index.htm?keywords=btv-dl09&t=SupportSearch
Go to this link and download the Rollback package and then do the dload method. You will come back to Stock ROM and your bootloader will be locked again. Download both files. Site is in Italian, you can translate it to English. This is the file I was talking about in my previous posts. It was uploaded by Huawei only on March 30th.
This is straight from Huawei so no risk at all and very safe.
They also have the B009 firmware so you can use dload method again and update it to that firmware. After that you can do whatever you want
I hope this is useful for you.
Cheers!
Sam :good::good:

I am glad you found it useful. Please have a look at all my posts in other threads as well. I have explained the steps in detail.
There is Android nougat available too. B006 -> B009 -> B010 - > B301 - > this is the path you need to take to get to nougat if your tablet model is C100BXXX. And all these firmwares starting from B010 are available on firmware finder app.

P8Lite stuck on huawei logo - had access to TWRP

Hello, it is my first post on this forum and it of course has to be problem. I am not expert in mobile phone hacking/flashing and this issue is too big for me to handle.
So like 6 hours ago i had working p8lite L21 with official android 6.0 and locked bootloader. I really wanted install costum rom due to performance issue, so i downgrade it back to 5.0 lolipop, than I root it with kingroot and successful extract key and unlock it using this tutorial: https://forum.xda-developers.com/newthread.php?do=newthread&f=4627
Than I flash recovery and install TWRP 3.0.2-0 and it all just worked. I was so happy that i manage to pull this off and I forgot that now i have EMUI 3.1 (ALE-L21C432B170) and i flashed phone with this:
https://forum.xda-developers.com/p8lite/development/rom-lineageos-14-1-p8-lite-t3824247
Of course it bricked because I missed that part with special version of TWRP. After that i tried to install something older just to get phone to work again:
https://forum.xda-developers.com/p8lite/development/rom-cyanogenmod-13-0-ale-l21-t3708835
And surprise, surprise, it did not work either and now I am stuck with huawei boot logo.
I did some research how to fix this issue, but i found so many different problems and solutions, I thought that at this point I really should ask for help because I just have no idea what i am doing now At this stage, can i just flash some costum rom (idc what exactly, just wanna to be lightweight) or i have to somehow restore original firmware? And if so how to do it? As i mentioned, i had access to TWRP.
Thanks a lot for your help in advance.

can someone help me with unbricking this phone? ?
@edit ok nevermind, i thought that this phone is cheap anyways so why not risk and just flashed boot/recovery/system from stock rom with fastboot. I did it and it works again, i needed just this simple hint to do it but i guess p8lite forum is dead.

I believe I can help you... Check the First Comment of that post... you'll see two additional firmwares... Only those firmwares have EMUI 4.1... b896 is for dual sim and b895 is for single sim... use any of those as per your requirements... after that download the LineageOS firmware and then proceed as per the Thread's recommended way... Also, before installing LineageOS, make sure you don't have any lockscreen lock...
feel free to ask if you have any more questions...
PS: i may reply bit late... maybe an hour, 5 hours or even days... but will try to check frequently..

Do you mean Vol +, Vol - and Power Button by powerbutton +- ? That's one way of flashing it, if you get error by that method, try it once again. If it doesn't work at all, then yes extract the update.app and go for the hard way...

Yea, i mean that i holding all three buttons (power vol+ vol-) and than it just says that installation failed. To flash it with fastboot i need to just flash recovery/boot/system or more files? I am asking because currently i have android 5 and this firmware is android 7 and I am just not sure if i can just simply flash those files and it will works.
Thanks for helping me

Which one are you trying to flash??? b896?? or simply LineageOS??
If it's b896, then I did read that it can only be flashed on ALE-L21C02xxx, but i am unsure about it... I did installed LineageOS and Resurrection Remix back in the days but I don't think I ever used C02 ROM for B896...
Also if you have the latest TWRP, you can simply flash with it... Try it...
