Hello i want to downgrade from b320 to b180.
How i can do it?
My phone is totally stock...where i can download b180 firmware?
 
Unlocked Bootloader is needed
Download your Version here
Download the Huawei Update Extractor http://xdaforums.com/show....php?t=2433454
Extract boot.img, recovery.img, system.img and cust.img with the HuaweiUpateExtractor from the Update.App
Boot your phone into bootloader
Flash the img Files via Fastboot (fastboot flash recovery RECOVERY.img) etc...

or try without unlocking Bootloader
Copy the Update.app in dload Folder
In dialer * # * # 2846579 # * # *
Update from SD Card,this works from B320 to B180,but not from B321 to B180,I have tried it myself,if it does not work try again

i am on c432b320.
But with above the Methode its not working. even with kingtool its not booting after i flashed system,boot,cust &recovery.
I want back to b170 sooo bad.
B320 is not a good choice. apps are freezing (whatsapp, playerpro, threema, fileexplorer) Notification problem is back etc

pls , unlock bootloader + twrp + root
then try to edit ro.build.display=first line of verlist.img from c432B170 after that return recovery to stock then dload b170, try this method first.

if not working , on b320 debrand to c636 then go back to c432 again and edit ro.build.display=first line of verlist.img from c432B170 after that return recovery to stock then dload b170, I am on c636 this method is working very well , I debrand to c432 and back to c636 :)

you can see how to debrand in my thread on general section.

after successful , your bootloader status is locked again.

Your variant is C432 , You should use correct variant , but C432 and C636 , they can use instead. Show me your build number, pls


Build-# NXT-L29C432B320
or you prefer a Screenshot?

(the backup i wanna roll back later - is named (from twrp) NXTC900B170. but if i cant use this one, its not important. i just wanna go back to b170 or b180) thats all i want.

OK , First try to edit build.prop
- ro.build.display.id=NextL00C432B011 (Unlock bootloader+TWRP+ROOT > Use my tool >7 >10)
- Then return to stock recovery
- Flash any stock rom C432

Report me back

I cant get a connection to my phone via your tool. (Waiting for Device)
Even Huawei Suite (fresh installed) cant get a connection to my phone.
