Please give how to unroot for update nougat. - Huawei Mediapad M3 Questions & Answers

Hi guys.
First of all, Please understand although I'm not good at English.
I have rooted wifi version m3. (BTV-W09C233B030)
I use TWRP and installed SuperSU.
I used erecovery to erase and install TWRP.
and now. I want rollback rooting and upgrade to nougat.
To do that, I heard that the stock firmware was needed, and I downloaded the full version of the file(full version BTV-W09C233B029) using the firmware finder.
Can you tell me in detail from here?
Thanks : )

First of all, I would like to let you know that :
- I've successfully installed Nougat BTV-DL09-C100-B302 but... I was unable to root it with "twrp_BTV-DL09_5_greatslon.img" + "TWEP-SuperSU-v2.79.zip".
- I've then done a rollback thanks to the "C900B300 - ROLLBACK from 7.0 EMUI 5.0 to 6.0 EMUI 4.1 6.0" package from the Huawei website.
- Then, successfully re-installed BTV-DL09-C100-B009
(1) By putting update.app inside "dload" folder (to be created or to be emptied) on the external sdcard
(2) Switched off the mediapad.
(3) Switch on pressing Volume up+down+power button and install will start.
- Successfully upgraded to BTV-DL09-C100-B010 -> BTV-DL09-C100-B301 with "Firmware finder 4.2" downloaded the from Google Store.
Unfortunately, again, I was unable to root it and I've identified this error while flashing "TWEP-SuperSU-v2.79.zip" with "twrp_BTV-DL09_5_greatslon" : "Boot image patching" process fails to patch "sepolicy" and give the error "--- failure, aborting" ; basically, the SU binary is not installed in the System. It's a kernel issue and I guess TWRP has to be patched for these new ROMS or the concerned file must be patched differently, with another tool (BTV-XX09-XXX-B301/B302). Or I'm doing something wrong if someone else has managed to root its mediapad running these updates.
If you don't need your mediapad to be rooted or if you know how to root it , installing Nougat is quite simple :
1) First replace TWRP with the stock recovery image. To do so, extract recovery.img from BTV-W09C233B029 with "HuaweiUpdateExtractor" for Windows.
Considering that you have the ADB drivers correctly installed, reboot in fastboot mode with the command : "adb reboot-bootloader" (or adb reboot bootloader). Then type : fastboot flash recovery recovery.img and then "fastboot reboot". I'm doing all that under parallel destop (Windows 10) on a macbook pro.
2) Then, install you stock rom BTV-W09C233B029 :
(1) Put the file "update.app" inside a dload" folder (to be created or to be emptied) on the external sdcard.
(2) Switched off the mediapad.
(3) Switch it on while pressing volume up+down+power buttons. Install will start.
3) Download Firmware finder 4.2 from the google store and install the required Nougat OTA file for your mediapad thanks to the proxy method (localhost / port:8080 ; you will be proposed to download a Firmware Finder ADD-ON from the Google Store. It helps to push the local file to the official system updater in Settings). Not that you don't have to download the OTA file with the Firmware Finder ; you can just use Firmware Finder to trick the local update installation and then manually put the update.zip file on the internal sdcard in this directory : HWFF/null/update.zip. (Firmware Finder servers are very slow at times so you better download the OTA file yourself on the site mentioned in other xda threads).
Good luck.

Thank you
thank you very much!
It's a really easy way. I learned a lot thanks to this.
Unroot was completed without any problems.
Thanks again

My pleasure, glad you've been able to sort this out. :good:

You can try a factory reset. Used to happen to mine also when running BTV-DL09-C100-B006. Not occurred on B009 and Nougat. Can be caused by many things when unlocked / rooted / xposed framework and so on installed. If stock, I would do a backup and try a factory reset. I also remember having tried to activate both navigation menu + fingerprint sensor for navigation than removed the navigation menu and it had solved the issue if I remember well. Maybe a coincidence though... don't know.

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:
Hi Sama, below in bold my answers.

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.

The bootloader is still unlocked. Do I need the unlock code, in order to lock it again?

I'm not sure that I still have custom recovery, cause I cannot go into it anymore...

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:
Cheers!

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?
Hope - Stock Rom - BTV- W09C128XXX

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

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:

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:
Cheers!
Sam
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.

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.

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

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:

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!

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.

Bricked, wiped chinese BTV-DL09 4G

Long story short; I wiped system and everything on this device, so all I really have on it working now is TWRP. The official FullOTA updates fail in TWRP, erecovery fails, and recovery in hisuite fails. I assume the last two will fail because of the third party recovery. So I guess I'm wondering if anyone can point me in the direction of the official recovery that I can fastboot flash, or any other way to reload the ROM?
Full story; I got this new tablet last week, and I unlocked, installed TWRP, and rooted successfully. Then I broke google services with a dodgy gapps install that I didn't need, couldnt figure out how to unflash it, and wiped everything like an idiot.
Thanks if anyone can help.
Update; I guess the root of the problem is that I'm unable to mount /data? Any actions I take in TWRP give me the error "Failed to mount '/data'", including if I do a wipe data or try to change the file system. I've used "Huawei Update Extractor" to see if there is a data.img, but it looks like no.
Update 2: Still not sure what this was all about, but I extracted system.img from "Huawei Update Extractor" and fastboot flashed that, and it looks like everything is working again. Haven't checked TWRP to see if it still gives errors on the data partition, but I'm at least in the OS and google play services are working.
Download latest firmware for your device from Huawei server and extract it. Make a new folder on external sdcard, named dload. Copy extracted file (update.app) in this folder. Power off device and turn it on using 3 button method: volume up + volume down + power - old all 3 buttons simultaneously.
It will start the update/flash process. It will install factory firmware on your device.
When you download Firmware, in the archive you will find these steps (PDF file).
Next time you can try this

Wrong. He installed TWRP so there is not a functional recovery.
The right thing is to extract the Recovery from the Update.app and flash it, then use the dload method.

Actually, I did try that, but I put stock recovery back on and and tried the dload method, it still failed int he same way as with TWRP installed.
What ended up working was extracting system.img from the update and fastboot flashing it. Not very intuitive. I am still getting "Failed to mount '/data'" errors in TWRP now, but haven't looked much into it yet. That is weird, I guess if everything is working it is more a problem with TWRP, because if everything is running and booting /data should be fine.

Mate 8 not working properly after erase data from TWRP

hi guys, hopefully someone can help me with my situation. I try to explain as best i can.
My Device: huawei nxt-L29
Build number : nxt-L29c636b585
( I install right firmware for my phone )
1. i follow this guide (https://forum.xda-developers.com/mate-8/general/guide-unlock-bootloader-root-install-t3301371 ) to Unlock Bootloader, Root, Install TWRP & Decrypt.
All working perfectly until last step "Decrypt",
Instead of format data - type yes... I do my mistake by click Advance Wipe and click Erase Data. And the phone stuck on loop bootloader.
2. I try to flash stock recovery for nougat and flash UPDATE.APP on EMUi recovery but failed.
Then I follow this guide for huawei p8 because i cannot find any related entry similar with my situation in Mate 8 forum ( https://forum.xda-developers.com/huawei-p8/how-to/guide-how-to-unbrick-huawei-p8-failed-t3260704). And use Huawei Extractor to extract boot.img, system.img and recovery.img and flash it in fastboot mode.
All work perfectly and my phone restart like normal.
3. The problem after my phone unable to lock gps correctly (cannot use all because always changing position),cannot turn on bluetooth and unable to change ringtone/notification, and maybe a few more problem. i think its because I didnt flash all file in UPDATE.APP.
4. The question is how do i flash UPDATE.APP and get it fully work, because if i flash on EMUI recovery it always failed on 1-5%? Just for info in Update.app, there is 2 recovery image which is recovery.img and recovery2.img, do i need to flash both to try flash on EMUI again?
Hope you guys understand me,i not english speaker...Thanks,
any question just ask below.
Opening one topic will suffice :good:
The mate 8 actually has 2 update packages, the undate.zip and the update_full_hw_eu.zip, both need to be flashed, can be done via twrp, I suspect you are also missing settings like update and apps like file manager, I've done it the way you have and ended up with that problem
Download and install data zip

Help force Full Update instead of OTA

I just received the information that there is a new OTA update WAS-LX1AC432B184, but it failed to install I think because it want to patch the system, vendor and custom partition instead of adding file. With Firmware Finder I found the full version, is there a way I can force my phone to use the full version and not the OTA to do the update?
Will it delete all of may files?
Thanks
I believe it will wipe your phone so you will lose all data.
To force the update put the 'update.app' file in a folder named 'dload' (if no dload folder just make one) to the root of your sd card.
With the phone dialer type *#*#2846579#*#* and select software upgrade or, turn your phone off and press and hold volume up and down buttons and power on the phone, this will force update.
You could also contact Huawei support (via Hi Care App) who might be able to help you install the failed update.
i received notification for WAS-LX1AC432B185 (i have the 4 GB version)
update failed, because i had TWRP flashed and after reboot it tried to flash the update in TWRP.
so, i flashed stock recovery in fastboot and then the update was succesfull.

I tried the same, but it doesn't work. I added the update of some System application inside the System Directory and I think that this is the Problem.
Reading the script for the update/rebrand for Mate9 and P10 I found this command:
$ADB shell "echo --update_package=$TARGET_UPDATE > /cache/recovery/command"
if I download only update.zip from Full-MT through Firmware Finder and copy it for example in /dload (adb push update.zip /dload) and then launch
adb shell " echo /dload/update.zip > /cache/recovery/command"
adb reboot recovery
Will it update my phone without doing a factory reset like if it was an OTA update?
In the update.zip there are the full Version of System, Vendor and Custom Partition instead of only the patch files.
Thanks
I tried but it doesn't work.
I found a tricky solution.
I accepted and download the 3 update files then I don't do immediately the installation, but I substitute in the directory where they where stored (/data/update/HwOUC/serie of number) the update.zip with the full-OTA that I downloaded through FF. I had to change owner, group and SE contest with that of the original file.
After that I tell the system update to perform the update.
The phone rebooted and the update started at end I received an error message, the system rebooted showing the old version B182 but patch updated to 1st September.
Immediately I receive a notification of a system update, but this time the FULL-OTA was proposed I did again the update and this time everything works fine. NOw my Telephone is B184
After that I had to reinstall TWRP and reroot it.
Hope it helps

P9 lite No audio After TWRP restore Dload failing HELP

Hi, my english is bad too , B389 is an OTA update, its impossible upgrade via fstboot or via TWRP (error 7). IMO the right way to fix your problems - downgrade to MM , then back to Nougat etc. (remove pattern Lock , Fingerprint lock, root etc. before installing downgrade). It will erase all your phone data!!!
Download official rollback package for your VNS-L31C432
http://download-c1.huawei.com/download/downloadCenter?downloadId=93789&version=373429&siteCode=sk
and download MM firmware VNS-L31C432B161 (Single SIM)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66022/f1/full/update.zip
1) Create a new folder dload in root directory of SD card (root directory : it means dont put it in any folder .) Now unpack the rollback package and copy its contents “UPDATE.APP” to the “dload” folder. Use the 3 button combo installation. After your firmware version should now be on “B300” or "test-keys".
2) Remove from dload folder rollback package, extract the ZIP file with MM firmware to the dload folder and use 3 combo button installation.
Or you can use this method : on your phone launch the phone dialer app and dial *#*#2846579#*#*. Next, select Project Menu – > Software upgrade – > SDcard upgrade – > and confirm the flashing process that is about to be initiated.
Good luck!

http://download-c1.huawei.com/download/downloadCenter?downloadId=93789&version=373429&siteCode=sk
and download MM firmware VNS-L31C432B161 (Single SIM)
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1164/g104/v66022/f1/full/update.zip
1) Create a new folder dload in root directory of SD card (root directory : it means dont put it in any folder .) Now unpack the rollback package and copy its contents “UPDATE.APP” to the “dload” folder. Use the 3 button combo installation. After your firmware version should now be on “B300” or "test-keys".
2) Remove from dload folder rollback package, extract the ZIP file with MM firmware to the dload folder and use 3 combo button installation.
Or you can use this method : on your phone launch the phone dialer app and dial *#*#2846579#*#*. Next, select Project Menu – > Software upgrade – > SDcard upgrade – > and confirm the flashing process that is about to be initiated.
Good luck!

Yes, you can. Via OTA, or you can use TWRP (Meticulus 3.0.2.0 only ! ) and flash both .zip files. You must download two files:
http://update.hicloud.com:8180/TDS/data/files/p3/s15/G753/g104/v80474/f1/full/update.zip
and
http://update.hicloud.com:8180/TDS/...-L11_hw_eu/update_data_full_VNS-L11_hw_eu.zip.
In TWRP set Install, then select memmory SD card, and klick on
update.zip, confirm installation. After, STAY in TWRP, go back to Install, find file ...hw_eu....zip , confirm installation. Then select rebot system. Done!

Try it, but I think, you will get a message "not compatible" . Via dload its impossible, IMO use rather Huawei firmware finder or wait for OTA update.

If I said, it's impossible manually update to 381 or 389 using OTA firmware, trust me . Try Firmware finder. GL!

FF works with proxy fine, but you must first download and install Firmware finder proxy apk. On Nougat use TWRP 3.1.0-2.
