[Discussion] Rollback package for various models

Hi Folks,
Seeing around various section of all the models when users are struggling to restore their phone either due the flashing an incorrect firmware or after updating via Firmware Finder app and then wanting to rollback to earlier version of EMUI. They sometime cannot even flash the custom ROMs due to FRP lock or unable to flash the custom recovery and even after trying all the known methods, we struggle to restore their phone as they messed up badly with their phone and model or version change to something unexpected.
In this thread, lets discuss and share about rollback files available for various models (be it MM, Lollipop anything) so that new users could use it to restore to their original version and then update to official versions.

Hi,
thank you for this discussion.
I'm a new KIW-L21 user stuck on the firmware B370.
I read a lot of post and try update.app, stock roms, custom roms, TRWP backups, ...
So far impossible to downgrade to a pre-VoLTE L21 firmware to flash LOS.
I hope I will find a solution other than selling my phone.

Just boot to twrp.
Backup system+boot
Zip it. It will be around 1 GB with no personal data of yours.

Great to know that you managed it. Did you flash any recovery at all? Will try later to boot to TWRP and flash what you shared. Thanks!

You're right, I flash everything in the twrp backup except any recovery.

HUAWEI Enjoy 7S (FIG-AL10) rebranding to HUAWEI P Smart (FIG-LX1): feasible? how?

I bought a Huawei Enjoy 7s (FIG-AL10) in China, but now I would like to rebrand it to a European version (FIG-LX1).
I read tons of posts suggesting to use TWRP, but there is no TWRP available for this phone.
I found a firmware for FIG-LX1 version on Firmware Finder, but now I do not know how to load it into the phone and rebrand it.
Any suggestions?
Thanks.

I bought the huawei P smart which is the European version of Huawei Enjoy 7s. i think we should wait for a forum to be opened here for this device before we can do anything like unlocking bootloader or Rebranding and rooting.
just be patient bro.

I've just found a procedure to root Huawei P Smart, but XDA does not allow me to post the link.
Try to look in google: "Huawei P smart - Root - Anleitung".
It works perfectly. I tried it out on my Huawei Enjoy 7S.
Next thing would be to flash another firmware to change from Chinese to European version, but I'm still not sure how to do it.

I just tried, but system.img writing failed.
In the rescue.exe compressed folder it seems that there are two files: system.img and vendor.img.
Is vendor.img to be renamed to cust.img?

Sorry. I uploaded vendor instead of cust. Will replace the download by tomorrow.
Just translated the tuto:

I tried to flash from fastboot cust.img and system.img of P Smart on Enjoy 7S but writing failed.
Probably rebrand on this phone involves other partitions or files (oeminfo?) that I'm still not aware of.
I hope a procedure for rebrand will be released soon.

Have you had any luck? I see there is a TWRP out and an update at the above link to android-hilfe forum. I did post a reply there but seem to have had my account locked for now :crying:, so though i might see how you did while i wait for help.

Thanks so much, really appreciate the help. I will do so in the future.
Just to confirm what would be the reason to flash and install a TWRP? For dev reasons only?
Or just to remove all the preset Chinese settings?

@ChinHon
Interesting i can install all the services from Google-Installer-v3 onto a Enjoy 7S, but can not open the Play Store or Drive as it just hangs on the loading screen. And never actually goes in.
Haha, im stumped .

Find the current Playstore Apk from the net and install it.
TWRP is necessary for Magisk rooting or to create backups or flash zip`s.
I can't help much with dabranding. I don't know very much about that.

I tried in several ways to install C432 firmware on my Enjoy 7S, but no way to flash System.img.
As soon as I flash C432 oeminfo file FRP gets locked and I cannot flash anything anymore.
I tried also Dc Unlocker tools, but System.img flashing stops with the message "Sparse flash write failure".
I'm still looking for somebody who managed to rebrand the Enjoy 7S to P Smart.

I wish i could help,I cant currently even get any Google option on the Enjoy 7S to run. Even trying to add a google account to cloud just freezes. Seems as soon as any Google option is chosen, the Google Services just states "Restarting".
Out of options.

Google services installation was an easy task compared to rebrand.
Download GMS from the link below:
https://mega.nz/#!WqYwyLyD!l7H8WRHBHs0ZwpyE0w2c7n6AvTSpTF29KjjX7_MM2u8
Procedure:
1. Install GMS (it is going to clear all previous google apps and restart the phone)
2. Install google play that I included in the zip file.
Let me know. For me it worked like a charm.

Stubborn P9 Lite wont flash any firmware [help please]

So, I have a Huawei P9 Lite (VNS-L21) and I have a problem: when I boot it up I see the "Your device has failed verification..." message.
I did a hard reset (factory reset) but when I boot it up it asks me for a password and the keyboard doesn't work.
I googled around and I found a lot of posts and I tried everything, no luck.
My bigger problem is that I don't know my phone's model number and firmware version. So I cand find the proper firmware to flash.
The only thing I see is the VNS-L21 on the back. Also, I took the back of and I saw two codes (I don't know if it helps): GA20 and 160521H2
Also, (with DC Unlocker and the the phone in fastboot mode) I managed to get the IMEI and serial number. The SN is: BUC4C16519008689
Now, from many other XDA posts, I know that I have to download the update.zip archive, extract the update.app file and add it to a micro sd card in a dload folder, press vol up + vol down + power and the updte will begin.
Did that but the result was "Software install failed".
I tried to use FirmwareFinder (from Team MT) but I didn't know what firmware to use, so I used this page: https://romfirmware.com/stock-rom/huawei/huawei-p9-lite-vns-l21/
I belive (from checking my IMEI here: https://imei24.com/imei_check/Huawei/) that my custom region provider code is C432 (Europe).
So I searched on the page for a VNS-L21C432B... firmware version, but I don't know what version to choose.
I attached 4 photos so you can see what I'm talking about.
So, any ideas on what should I do next?
Thank you!

Hi, try my way. https://forum.xda-developers.com/showpost.php?p=77307223&postcount=30 Just pick CxxxBxxx that suits your model. Kinda wondering how you don't know your phone model, did you steal it lol.

Thank you for the info. I read that post and did a little bit of searching but, as I said, the issue is that I don't know my phone's Cxxx code 100% (not sure is the European version, as far as I know it might be imported). Also I don't know at all the Bxxx code.
So what do I have to do in order to get the right one?

Make sure, phone and FRP is unlocked. There are plenty of threads with unlocking and tools.

It's been some time since I tried to fix this phone because of some medical problems.

Also other thread said that I need the bootloader code but I can't get it from the phone.
Any ideas please!?

Without unlocking code you can't unlock the phone

your bootloader is unlocked but the frp must be unlocked to , the problem is that to unlock frp must boot your device. The only rom that may fix your problem is this l21c432b370 FullOTA-MF-PV it is the PV, with this rom i unbrick my p9 lite
This rom is for L21C432B370 if your model is l31 you may brick it more or not work at all

My (other) problem is that I don't know for sure what exact model is because I can't access the settings. All I managed to get with DCUnlocker is this:

Firmware : NRD90M test-keys

If I try your l21c432b370 FullOTA-MF-PV rom can I do something that is irreversible?
Btw, you said "it is the PV". What PV means?

PV means point version and is used to move between android versions
If the readings are correct your rom is NRD90M test-keysand you have the l21 , so the NRD90M test-keys means that its problematic rom (it come up when upgrade from android 6 to 7 in huawei phones , if you look here you will see to many problems like your, some are lucky and fixed some are not so lucky) , what do you mean irreversible when you have a bricked phone? you can download this rom and try to install it with dload directory , i thing its the only way that you can try

Hello,
this happened because you
choose that firmware...
you are very lucky you didn't bricked your device.
You could try to use Firmware Finder again
to revert back to your previous version,
but as i told, you could brick it,
that's your choice.
Another way is unlock the bootloader,
install a custom recovery (TWRP),
flash an OEMinfo file and your correct firmware.
It depends on the android version,
on the region (CUST) in which you live
or for which the firmware has been released
and if the device is single or dual sim.
Good luck dude !
P.S.: took a look and it seems
the link for Hassan's twrp download
is no longer available...

You can try flash it with Service ROM Download . Type VNS-L31, or VNS- .
Download correct firmware - EMUI version, Cxxx (the bracketed (Cxxx) is your device’s regional variant.
This number is very important in determining the correct firmware to download. Select your previous Cxxx, not current C00 ) and single/dual SIM (all firmwares that end with even numbers are for dual SIM, odd numbers are for single SIM).
Instructions can be found in 'ReleaseDoc' folder.
If you cannot unpack downloaded zip archive on PC, unpack it in the internal memory using this RAR apk.
Extracted 'dload' folder copy/transfer to the SD card. Good luck.

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:

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 :

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.

Have you tried to upgrade via eRecovery & Wi-Fi?

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).
