How to revert to C128? - Huawei Mediapad M3 Questions & Answers

Hi
I bought an M3 Wifi US version BTV-W09C128, which was recently upgraded via OTA to Nougat B353.
I used the rollback files on a European Huawei site
https://consumer.huawei.com/it/support/tablets/mediapad-m3-8/
to downgrade to Marshmallow BTV-W09C100B006 to regain 5 GHz Wifi, and then found it was not possible to upgrade to Nougat.
I opened the calculator in landscape mode and enter () () 2,846,579 () () =
finding
Vendor Country Info (same as oeminfo?) shows
Vendor: hw
Country: usa
This seems like the reason why my M3 cannot do OTA updates now.
Does anyone know if there are files available on a Huawei or other site to enable me to revert the M3 to US C128?
Thanks in advance!

Hello Sam,
I did the same updates on same type of device. You can try firmware finder to download the update files. I was not able to use this, I am trying for 2 days to get back to Nougat, tried chinese, european and US versions from US. I also had some hard times getting back to android 6, after different firmware updates I got stuck on NRD90M test-keys firmware. Now I am back to android 6 using the rollback and firmware from huawey italian site but I'm not sure why it worked on 10+ try...
If you find a way please let all of us know the flow
Thank you,
Mircea

I did the same thing. I don't think there is a full stock rom for C128 out there that you can flash it back. I have done lots of search on the internet already. However, I like to have 5Ghz enabled and I don't like EMUI 5.

hi first post please do replay thanks

Hi I am new to this so please do bare with my lack of knowledge
first things first I never had been in the P9 Lite Beta I brought the phone and I have never installed any roms or so on
my question is it seems my phone is branded to the Germany Telekom
that's where I brought it makes sense my question is I can not go away from the
firmware or can I go from there firmware to another firmware like the one you can download from there main site that is unbranded
why do I think my phone is branded is because I have tried the Update.app from the 27.03.17 I do the dial code and it restarts it starts goes to 7 percent and it cuts out
failed to install reboot phone and it goes back into the 6.0 Marshmallow
I am wandering how other people are able to install the B170/B171 update I know my Phone Model is (Huawei P9 VNS-L11) but the Phone Model is Huawei P9 LITE Vns-L31 ???
how are people in Europe to install the phone prove its the final code an not the beta since I am not able to update an may people are saying its finished and it being rolled in OTA
what do I have to do to remove the Telekom software and install a stock rom without it being locked preventing me from installing the update to 7.0 please replay thanks you and enjoy the weekend

Nokia 6 Official TA-1021 Firmware required, Help

Dear all devs, as its been very struggling during any test on nokia 6, one wrong OTA tooks us to let us install june updated mena firmware, everything is fine, even after installing it shows that the nokia 6 is with TA-1021 but when i saw with the help of buildprop editor, it shows that our phone becomes TA-1025, and thus have to update manually every patch, but still no luck for OREO OTA, still stucked on it, even manually it gives error and then there is no recovery option too, please help us, it becomes the major problem now, the OTA server get confused over as TA-1021 as externally and TA-1025 and thus it wont provide any update and we stucked on our current Build.
Please provide any official TA-1021 firmware so we can be up to date with our phone with official updates
also make some custom rom too, as its been very long time, customs roms are debloated and hence a 10 times more faster and functional then official rom.
There won't be 1021 frimware version very soon,i'm now in the same situation as you.
i m looking too for ta1021 official nougat firmware, all link in xda and 4pda are for ta1025.
please anyone help us to find the official firmware for ta1021.
The absolute legend sltushar, the OP, showed me how to flash official firmware for the TA-1021
The guide he gave me can be found here: https://forum.xda-developers.com/nokia-6/help/compatible-firmware-t3783503 in case you haven't found it yet.
Good luck, and happy flashing!
We need firmware for TA-1021 with extension .nb0
Hi! Use this
https://www.firmwarefile.com/nokia-6-ta-1021
The one you gave the link is for box user, the infinity box CM2 Qualcomm version, and it cost arround $70
Hi, i am not sure which for which version but i found this ftp link, where there are several Nokia 6 firmware. experts also take a look , may be make a new permanent thread for firmwares.
http://dl.infinity-best.com/download/index.php?dir=flashfiles/Nokia-6/
please check the link.
MENA Firmware is enough for now,because you will get Android Oreo OTA soon as you check for updates (after fresh install of firmware MENA),with will change your phone back to original state,if was TA-1021 it will be TA-1021 .

oeminfo on M3 Wifi version BTV-W09?

Hi
Does anyone know how to read oeminfo on M3 Wifi version BTV-W09?
I found the method using the dialler on M3 LTE version BTV-DL09, but it does not work for W09.
Thanks in advance!
Hi again
Found the method.
Open calculator in landscape mode and enter () () 2,846,579 () () =
Vendor Country Info (same as oeminfo?) shows
Vendor: hw
Country: usa
My M3 is a US Wifi version W09C128.
Now I have rolled back to Marshmallow using European firmware, and the build number becomes W09C100B006.
Cannot obtain OTA updates, due to conflicting oeminfo?
What's next?
Any suggestions most welcome, and thanks in advance!
PS Already tried flashing Nougat B302 on Firmware Finder unsuccessfully, ending up with NTV90M test key build number.

P10 Lite (WAS-TL10) Stock ROM files

Hello all,
I'm looking for the stock rom (EMUI 5.0/Android 7.0) firmware files for my newly acquired P10 Lite (WAS-TL10).
Bought it at AliExpress, was supposed to ship with Android 7.0, but got Android 8.0 on it.
Unfortunately I need Android 7 for the sole purpose of verifying some Huawei allegations in which they pretend my app is not working properly with HMS Core version lower than 2.5.3! A version you can't find anywhere on any devices, but those Huawei phones running Android 7.0!
I say they pretend because they've made-up all kind of new rules for the past months to just prevent my apps from being published in China, as explained here: https://www.3c71.com/android/?q=node/2784
Any help would be much appreciated.
This is the only Android 7 Stock firmware I could find:
Huawei P10 Lite Dual

Thanks but the download link doesn't work at all. I've found hundredth of such links but none works. This one ends-up with 'an error occured'.
Is it the same for you or are you able to download the file?

I'm sorry, I should've checked the link first, it seems like these files were removed from Huawei servers, however, there's AFH which, luckily, has the nougat firmware.

Try to downgrade to Nougat using Hisuite (official and safe way to do the downgrade). A7 firmware will not help you, there's no way downgrade (with locked bootloader) . Try chinese Hisuite :
https://mega.nz/file/1p9xyIRL#bx1M6zXqtrR38okQd4YqkYvmLfRaOBDJ2snjd8W7kqk
If the rollback option is not available with your HiSuite ("switch to the older version" or "Earlier version"), you must downgrade to the lower Oreo build version number doing the dload method (flashing Service ROM for your model and region).
Hi...
Like @-Alf- said you can try it this way. If it doesn't work for you. Search this forum for Service Rom to downgrade from emui 8 to emui 5. But be carefully by using any method. Make a full Backup of your System before doing any change. If you will downgrade to emui 5 for unlocking the bootloader. Better think about to use the Dc-unlocker for that. It will cost 4€ to get the unlock code. But its without risk to brick your device and it doesn't waste time to get it. You need to choose wat is more important for you.
So good luck

Thanks all, I was able to downgrade to EMUI 5.1, which allowed me testing very old HMS Core (2.5.2) somehow and its upgrade mechanism. Not sure I needed that device as it seems EMUI 5.1 didn't come with AppGallery at all, LOL.
Now I'd like to upgrade back to sell the device, but I haven't found a way to do so... Hi Suite tells me device is up-to-date, and OS system update tells me the same

Build number is WAS-TL10C636B187
I found a firmware, but it doesn't seem compatible ( Warsaw-TL10HK 8.0.0.371(C636)_Firmware_8.0.0_r1_EMUI8.0_05014HTC ) because upgrade says there is no update file on SD when I put the dload folder on it.
EDIT: That firmware contained zip files instead of .app, so I extracted the .app files and recreated the expected structure, and it processed the update using OS menu ( *#*#2846579#*#* ).
If any-one need the modified file, let me know.

No idea what that is lol.
After modifying the dload folder to have .app files (instead of .zip), the phone took the upgrade (editing previous post). New build number is WAS-TL10 8.0.0.371(C636).
I can now upgrade/downgrade between Android 7 and 8 for testing. That's pretty useful, so thanks to all.

WARSAW is the Name of the Phone...an p8 lite 2017 is called Prague or an Samsung S6 Edge is called zerolte
If you try to flash a firmware with another Region like C432 for Europa on a Device with C636 Asian Region...the verifying of the Update Package will not pass and update proceed will abort.
If you want to change the Region of the Device you need to use HWOTA Method for that...in the Script during configuration comes the Question to change firmware or to change location.
But be carefull by changing the Region cause the Devices for the different Regions could have different hardware integrate. Hardware like modem and so^^
OK thank you, i think modified firmware provided by 3c will work on my device as is has the same code of region c636 and the firmware flashed on my device is Asian pacific (c636)

Jfyi, the Huawei update server is down since February, so Firmware Finder is dead. Therefore, it is also not possible to use HwOTA or HuRupdater (unless someone has the necessary files stored on the disk).

dTab Docomo Version

Hi Guys,
Need some help. I had purchased dTab Docomo Version mediapad m3 8.4 lte 16gb version. It had emui 4 on. from https://www.ebay.co.uk/itm/284180861165?var=585666759904
I thought i would try to get lineageos 17.1. on it
Started the updgarde to EMUI 5. FOund stock rom. Although it updated, I think it was wifi only verison, lost the dialler and the ability to rotate.
Tried to find stock rom to go back. Only version i can see MediaPad M3 Marshmallow Firmware BTV-DL09C100B009
I have reverted to tis image but still have no rotation. Assuming it's not the right version. Think theses are JPN versions.
I really need to get this back to correct version 4.1 and then at some point upgrade to correct version of emui 5.
If somebody could point me in the right direction with correct files. The bootloader currently locked, i can unlock it but havent done so yet...
