my old build l21-c185b160
i upgrade l21-c185b525
now i want to downgrade l21-c185b160
how to do this. please help me.
You must have your c185b160 update.app file, you'll also need Huawei Update Extractor download link : http://forum.xda-developers.com/attachment.php?attachmentid=3262544
And minimal fastboot, link:http://forum.xda-developers.com/showthread.php?t=2317790
Now unzip the downloades extractor zip file amd install it.. Open the extractor and browse update.app (b160 update.app). After browsing, you will see many files; image files (system.img, boot.img,etc) amd other files (meta-inf, etc).. Among them you'll need only 4 image file; system, boot, recovery and cust..
Unzip minimal adb and fastboot and install it.. Now open it with administrator privilege and flash in this order:
Fastboot flash boot boot. img,
Fastboot flash recovery recovery.img, Fastboot flash cust cust.img,
Fastboot flash system system.img..
If flashing is done, you're on b160

ok i didn't find it too.. but i found the one for c185b120...
here is the link: http://www.carbontesla.com/2015/06/huawei-p8-lite-l21-b120-emui-3-1-stock-lollipop-firmware-pk/
you can upgrade via OTA from there...
first of all,notice my problem warranty check (not that message appear after logo), warranty employee check device in bootloader ,
so i can remove message with flash stock rom and recovery , and when i get info about bootloader gave me it's LOCKED , but in bootloader screen two line with red color shows Phone unlock(it's shows the phone at least one time unlocked and warranty was void) and frp unlocked.
The question is HOW TO FIX IT TO SHOW LOCKED WITH GREEN COLOR as same as device locked?
I don't think you can.
To my knowledge, the best you can do is fastboot oem relock unlock code, but that will leave you with the relocked status.
I've tried fastboot oem lock unlock code but that doesn't work.
Flash oeminfo via twrp it will LOCK not relock your bootloader and then you must use 3 buttons method to update on MM if you are on Nougat.
Flashing the stock firmware through the dload method relocks the bootloader.

You didn't flash it correctly. if for nougat update.app must be 2.5GB.
Also it wikl fully LOCK, not relock bootloader.

You need to extract the zip file from update.zip and put UPDATE.APP in dload folder. That's how I locked bootloader on nougat.

or you how done it . are you upgrade from mm to N ? give me your file and tell me how to flash it,
my phone is p9 lite vns-l21 , after downgrade to mm b 160 and in N b336..
i used THIS
When you upgrade to b336.
1. Unzip update.zip you flashed
2. Create dload folder and put UPDATE.APP inside
3. Reset phone and press 3 buttons
4. EMUI will update by itself and will lock bootloader after it's done.
