Hi,
1) wipe Dalvik & cache, flash stock recovery of b370, and then do like you wanna update to b380 using firmware finder, (use the big file)
or
2) rollback to MM : flash oeminfo for your location (recommended) , flash Rollback Package via dload , and then flash stock B160 via dload.
or
3) remove root from SuperSu app, then use Rocatex uninstaller

Alright I think I'll use the second method. Do you know where I can find the L31-C432 oeminfo?

Im on C66 how to update on newer firmware version?

So,
My phone is vns-l21c66b131 and is there any way to update to newer versions without rooting and if possible can someone write steps on how to do it?
If you use <SEARCH> you find followings:
<After a few day of reading users personal experiences regarding upgrade to Android 7 Nougat i make the big step myself...
My device is VNS-L21 model and entire process goes flawless...
Device state was stock MM VNS-L21C432B150, bootloader lock, dualsim enabled.
1. Unlock bootloader folowing by Automatic Factory Reset.
2. Flash TWRP
3. From TWRP i flash Meticulus TWRP
4. Reboot to TWRP and flash update.zip and update_data_full_VNS-L31_hw_eu.zip, both flash ends with errors, without reboot between flashes.
5. After that, i reboot device and boot in system ok, start configuration, etc.
6. I reboot to fastboot and flash Nougat Recovery reworked by @BadWolfYe
I am not experienced camera bug, all works fine and i have now a fully functional phone.
BTW, dualsim remain enabled and works both sims.
Thanks to all contributors for these pieces of firmware, first of all to @BadWolfYe!>
For that's is <SEARCH>, not to open another topic for same problem...
Thanks for the reply, but I'm not talking about Nougat, I talk about MM b161 update. How to do it if my carrier is c66 and the newest update there is b131

If you want to stay on C66 you have to wait to OTA updates...
If you make any upgrade via dload folder on sdcard your phone will go from C66 to C900 (global)
Another alternative is to debrand your phone to C432 (hw eu)
For any of this is treated here in some topics...
So I just need to create dload folder and put the zip there?

Problem downgrading to MM from N

Hey guys!
I've installed the Nougat beta for my P9 Lite VNS-L21 Dual Sim, but now I want to downgrade to MM. This is what I did:
0. Installed Nougat via Melticulus TWRP
1. Installed Revolution Recovery (because Melticulus TWRP had stopped working, idk why)
2. Flashed OEMInfo
3. Copied Version B150/B151 (I've tried both) to the SDCard
4. Started the P9 Lite with Power + Volume UP + Volume DOWN and tried to flash one of the versions.
I'm stuck here, the Huawei Recovery says the following: "Software install failed! Incompatibility with current version. Please download the correct update package!"
I've used HTC Mania, Thread NR 1200630 to download the stock rom for my P9 Lite, I've tried both the VNS-L21C432B151 Android 6.0 EMUI 4.1.1 Europa and the VNS-L21C432B150 Android 6.0 EMUI 4.1.1 Europa

I have L31 and I want to debrand it from C440 to C432. I did some research, but still I have some questions.
1. Unlock bootloader + TWRP + root - I found this https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701
It's ok right ?
2. Flash oeminfo of C432 and this should be done by SRKTool and oeminfo I found there https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873
3. repair firmware via dload folder - Unfortunately I don't know how to do it. In the instructions for p9, it was done also in SRKTools using "Install Recovery 6.0", but there P9Lite is not mentioned, how should I do ?
4. Install new ROM - I should install new ROM for c432, right ? It's using 3 button method ?
And that's all ?

Regarding <3. repair firmware via dload folder>, you have to download stock firmware for C432 (B130/131 or B160/161 - depends what oeminfo you flash),
unzip update.app and copied on dload folder on microsdcard. Power off and power on with 3 key combination and repair start...
At the end you have a brand new C432B1XX phone...

Indeed, you lose bootloader unlock, twrp and root (if you have).
If now I have c440B160, and I place oeminfo for c432 do i have to install c432b160 or I can install c432b131, because I only found that version
I installed TWRP and Root, and now I don't know how to change oeminfo, because in srk is only p9,not p9 lite, and I downloaded package .zip and tried to install it by TWRP but it didn't work. How should i do this ?

[TUTORIAL-easiest] Rebranding to L19 C10 (Russian, EU) for Oreo update + video

Hi, I will show you the most easiest way to get oreo update (emui 8).
you must have installed twrp and unlocked bootloader.
1. Download this https://forum.xda-developers.com/honor-8/development/tool-srk-tool-huawei-bootloader-root-t3470823
2. Press 7 then 9, next 7 and 5.
3. Now download 2 files: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1276/g104/v64076/f1/full/update.zip thanks to @jithendrav83
https://www.hihonor.com/uk/support/details/index.html?DOC_ID=92135 <- first
4. flash it by dload method
thats all. Now update your phone by huawei built-in updater or firmware finder.
But for me the best option is unlocking bootloader again, root then flashing by this tutorial: https://forum.xda-developers.com/honor-8/how-to/guide-flashing-unapproved-firmwares-t3668306
(method 2)

As you wrote, then the update will wait forever.
At this location you can, because. on the Russian version in the folder "cust" is your region. I recommend that you visit the Russian forum 4PDA.RU

As per my guide, you only lose it if you're rebranding to AL/DL (chinese). Rebranding from L02, L04 to L09 is perfectly safe (I'm running L09C10 on my L04)
So best way to get Oreo on L04 is to rebrand with this method and redlotus to the Russian EU firmware and everything will work?
Hi,
I rebranded FRD-L02 to FRD-L19C10 and tried above steps. Installed Oreo by redlotus method. But got "data corrupted" menu and I formatted data. Now phone won't boot. Then I tried unlocking bootloader and phone booted. But sw version still shows B95 and its on Oreo. Looks like cust/region part is not flashed. Tried installing Twrp 3.2.1.0 and the one in Multi-tool, but phone won't boot to recovery. Its going into error mode. Any suggestions appreciated. Thanks.

If you look at the XML File you used for the RedLotus method, you can see that there are two versions in it (L09C10 and L19C10). I suppose that's the reason why it's bugging for you.
Don't know for sure though. Trying that method now too, will report back if that's really the problem.

To rebrand, you need an unlock bootloader.
1. Download the C10 oeminfo file https://drive.google.com/file/d/1VtOeGQ9GnKvcSVgraPP6-go6HCRbpyBB/view?usp=drivesdk. It is a zip file, extract it to find an img file. Reboot to TWRP and select Install Image and install the file to oeminfo partition.
2. Perform a complete factory reset in TWRP.
3. Download the latest Nougat (3 files package) for FRD-L09C10 through Firmware Finder. Flash it using HuRupdater https://forum.xda-developers.com/ho...l-flash-official-firmware-recovery-t3769279/.
4. After the flash is complete, reboot the device, unlock the bootloader again and flash TWRP.
5. Download the latest Oreo build for FRD-L09C10 through Firmware Finder. Using HuRupdater flash the three Oreo firmware files. Don't perform a factory reset this time.
6. Reboot your device. You're now on Oreo.

Doesn't work for me. Always results in a bootloop with "Your device is unlocked..." etc.
Same with RedLotus too. I don't know if it's the firmware you linked or the recoveries, but ehh... nah, probably gonna go back to where I was before.

Try to install Service ROM from SD card using dload method.
Link:
https://androidhost.ru/41d
Follow instructions in file "ReleaseDoc". (Read everything carefully before doing anything).
Through this process, your data will be deleted and bootloader will be locked again.
Dload method works with Stock Recovery only, you have to install Stock Recovery first.

Hey dude !!
So you bricked the device ....
I don't know why but if you want B412 firmware
you can use @-Alf- guide and re-upgrade via Firmware Finder
to B370 fullota-mf-pv first, then to B412 fullota-mf...
Or download a previous from B412 firmware (ex: VNS-L31C432B410 fullota-mf)
and use HuRupdater method to flash the firmware.
Extract then stock recovery from B410 via Huawei Extractor and flash it via TWRP.
Re-update finally to B412 using Firmware Finder.
I can help you doing this, worked on my ex device but i can't guarantee 100%.
Cheers

Please read carefully, Maestro :

Hello,
I reinstalled the custom rom that I found on the net: C432B414 with Hurupdater.
It works.
However, the bootloader is still unlocked ... however, I would like to return to the factory configuration with the bootloader locked.
