[Guide]Huawei Ascend XT - How to update from any version up to B180 after rooting

[clsA]

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

~New~ B180_Full_Update.zip
Note about B180 - If you have no wifi or the phone won't boot simply extract the boot.img from the rom and flash it with TWRP (Install Image) or fastboot (fastboot flash boot boot.img) also the AT&T Logo is missing for now but everything else works


Thanks To @madvane20 Download >> B170 Stock Full Update with Firmware

Where do I start if I have B140 rooted on my XT? Maybe some numbers or section titles would help answer that. Thanks .

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

 

[divineBliss]

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

You still start at the top and substitute the B150 files where their needed
the process is the same no matter what version your on

 

[clsA]

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

 

[divineBliss]

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

The guide is not complete ... 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 don't have the B150 files yet so it's hard to complete the guide

 

[clsA]

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

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?

no one has posted any threads about it

you should still try and be on the latest security patch while you phone is stock

 

[clsA]

@RN_ReFlux Thank You ! for getting the B150 backup and /cust.img

 

[dabadguycr]

Yes, someone is working on it but it is best to have your ROM up to date. You may not see a need for it but a lot of others see a need.

 

[RN_ReFlux]

@RN_ReFlux any luck getting the B150 backup and /cust.img ?

Yes, I have them, am working on zipping some of the larger files, then will upload to drive or dropbox, since I don't have developer access to afh yet.

Only think I forgot to do was get the post-root backup in TWRP. If you need that, I've already asked my cousin to perform the backup, I'll ask her to zip and upload them to me.

Thanks ... I'll post the files to my AFH account if you can share them through google or dropbox ..etc

 

[divineBliss]

If you request developer access, it doesn't take that long to get it ........ a few hour maybe if I recall correctly .

...

All the files are uploaded for your B140 to B150 update...
I'll be updating the guide soon.

The steps in a nutshell are

flash your stock B140 system/boot/recovery and stock b140 /cust
force flash the dload/update.app for b150 with the dialer code
boot TWRP restore stock B150 system and dd the B150 /cust
Flash SuperSU and Factory Reset (< optional)
reboot system and it boots to a clean B150

Guide is updated !

 

[divineBliss]

Has anyone been able to follow the OP to get up to B150 from either B140 or B130? Or even B130 to B140? Thanks!

Be careful upgrading from B130 to B140. Went from stock non-rooted B130 to B140 using the SD card update method and hidden menu. While it went through the update process without reporting an error but after auto reboot it still showed the same version but lost WIFI functionality, mac address showed mostly 00s and can't restore full backup from TWRP without errors on /data, etc.

Anyone know if there are .img equivalent of 2017-01-26-H1611.B130.stock.complete to attempt restore from either fastboot flash or dd?
