How to rollback from b350 to b170 or b191 with locked bootloader - Huawei P8 Questions & Answers

Hi, guys I would really appreciate any help about this. Thanks

Have you already tried this guide http://forum.xda-developers.com/android/development/rollback-android-6-0-m-to-official-t3285512?

Yes I did but I'm on 5.1 not 6.0

Downgrade
Google huawei update extractor and download it, copy update from phone to PC
Open in extractor and extract, then with fastboot flash: system, boot, recovery, cust, cache is also possible
Hope helps, DJilaniE-070

Unlock it, flash ROM, and then (re)lock bootloader

L04 b141 update how can I apply?

how can I apply the updater after flashing custom recovery (twrp)?
Basically you can't, applying OTA requires stock recovery.
And just one thing, 1.64GB for an update? I mean there isn't much in the changelog

That's cool, but how?!
I was notified about the update on the phone and then just pressed the update now button and it restarted in TWRP and installed by itself
That's great, I'll never have to worry about OTAs

OK, here is an update. I am rooted with TWRP and have been waiting for the full update package to become available. As of just yesterday the full update package is in the updater app on the phone. You must be connected to wifi for it to appear. Open updater, click on menu on the bottom, download latest FULL package B141. After DL it WILL FLASH THROUGH TWRP but you will lose root and TWRP. Let it do its thing then reflash TWRP through ADB and SU after that and you are good to go on the new update.

how did you kill the device?
Really don't know, unlocked the device and then system has been deleted
Get the full update.app and extract system. Flash that with fastboot in bootloader.
Already tried but says the file is too large (3GB of system)
I had the same issue but there is a way in the Fastboot arsenal to send the system img in a few smaller chunks...
Edit: apparently, newer versions of fastboot do the splitting automatically!

I want to downgrade my phone from 6 to 5 but I don't have PC to recover TWRP so I ask everyone can send me system boot and cust imagies? I will appreciate that!
You have to flash transition firmware first otherwise you'll lose your IMEI.
P.s not worth downgrading.

1. Extract cust image from transition firmware with Huawei Update Extractor.
2. Put your phone into fastboot mode (rescue).
3. Flash that cust.IMG
4. Reboot device.
5. Local update to any android 5 rom in Updater app

This is alot easier because only thing you have to do is flash the file, and done! I my case your method doesn't work, it don't mean it won't work at all, but some phones are dumb and don't want to accept new Cust file!
Why would you want to downgrade? Stock Marshmallow works great...

Unlock the bootloader even if it says it's unlocked.
Ok so now I unlocked the bootloader and viola twrp is back but I can't get my phone to start... Its asking for a password and says that the data is corrupt. So then I tried wiping it tru twrp and that has failed. "Unable to mount data". Help

In TWRP > Mount > untick and re-tick /data and then try formatting it.
Yip tried tht too... So the phone started back but it's reverted back to its original state... Locked bootloader, unrooted etc...
I can provide full service firmware VNS-L23C605B370 / VNS-L23C605B364 / VNS-L23C605B121
Ok... But can I use any of those tht you've outlined safely, becuz my phone works fine so far but it appears the data partition is damaged. Also the twrp recovery im using is 3.0.1 so I gonna try updating it.
Right... so I've managed to get my phone back up and running by flashing the recovery2, recovery, cust and system files with L23C605B120 instead of B102 as it was. i've also managed to install twrp and rooted it. I've noticed that not any version of twrp works. Only the 3.0.0 version. Now i need help with updating my firmware from B120 to B362 if possible. through the official updater i attempted to install an official update but it kept failing... any suggestions... anyone?

Hello
as I see you can use twrp 3.0.
then, from then b120 MM.
1 bootloader code.
2 installs twrp.
3 go to wipe. check all except SD card.
4 go to install, install update.zip b362 and install update datafull.zip b362.
5 restarts.
here is.
2017.02.25 VNS-L23C605B362 update.zip http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1258/g104/v77299/f1/full/update.zip
update datafull http://update.hicloud.com:8180/TDS/...-L23_hw_la/update_data_full_VNS-L23_hw_la.zip
now, for vns-l23c605, there is a firmware b374.
you can install it too.
to do it.
you had to download all the files (full-ota-mf-pv b362+full-ota-mf b374) to your computer and handle them with winzip.
