I'll try and keep this short and to the point. If you unlocked your bootloader and flashed TWRP and SuperSU, theirs a Good chance your phone will not return to stock and take OTA updates. Many of us have tried but for some reason the updates just fail.

Well we are lucky and someone captured and posted the 3 known updates and I'm going to show you how to flash them


New ~ All in One ~ update Instructions in Post 2


We now have a new way to do this, So the information below is just for information sake So bare with me while I get the Guide updated...

Other Files you may need

H1611.TWRP.New.img <<- This is the New Twrp by yuweng I Highly recommend everyone use this Version

minimal_adb_fastboot_v1.4.1_setup.exe

Huawei_Android_phone_drivers(1).rar

I have been working on this for some time and I now have an ALL in One Flash solution

This will allow you to flash a Single Rom to Update or Downgrade your firmware and Rom

As with any firmware update or downgrade I'm not responsible to what happens to your phone you do this at your own risk
(rest assured I have tested all these files and my phone is fine)

The Flash instructions are the same as any rom flash on this phone
Step one is to Boot to the bootloader and boot H1611.TWRP.New.img
fastboot boot H1611.TWRP.New.img
Swipe to allow modifications to System
then choose Mount and check system and cust
Select Storage Micro SDcard
Next is install and choose your Bxxx_Full_Update.zip
Swipe to flash
Reboot

That's really all their is too it, Just choose the File below that you want to update or downgrade too

Note: The phone always loads the AT&T logo and reboots the first time and then loads normally
First boot will take you to the setup screen if you formatted data

Another thing i noticed while test flashing these files is that the Data partition becomes Encrypted after the flash
This means before you can restore a data backup or flash a Rom like CleanRom (it includes data) you'll need to Format Data to UN-encrypt it

Also some roms may need to have SuperSU flashed after the Rom or the phone may not boot the first time after the upgrade.

AS Always make a complete backup of your phone before you start any flashing


Downloads

B160_Full_Update.v2.zip

B150_Full_Update.zip

I had to make B140 into 2 flashes but it works the same just copy both files to your phone and Flash A then B

B140_Full_Update.A.zip
B140_Full_Update.B.zip

B130_Full_Update.zip

Huge thanks to @madvane20 for helping with the partition layouts and testing and to @worstenbrood for the Huawei Update Extractor tool

You start at the 2nd half of the updated guide B140 to B150
the process is the same no matter what version your on

So I should start with B130 stock files even though I'm in B140 rooted right now?

... no you would start at returning your phone to Stock B140 and continue from their
flashing the B150 firmware then the B150 stock system and /cust

We have the B150 files and the guide is updated

If I can get back to B140 stock and take the B150 OTA, which files do you need?

We don't have the B150 files yet so it's hard to complete the guide

is that a trick question ? if you could get back to stock and take the OTA this post wouldn't be necessary now would it ?
The whole point of the thread is that no one who rooted has been able to return to stock and take an OTA

Why bother updating? Isn't someone working in Lineage for this phone?
