Working method to downgrade emui 3.1 to 3.0 for H60-L12



I have been looking for a method to downgrade my L12 from lolipop emui 3.1 to KK emui 3.0. I found this method here - http://forum.xda-developers.com/hono...i-3-0-t3142268 , is for L04, and I adapted it for L12.


1. FLASH BOOT.img, CUST.img, RECOVERY.img, SYSTEM.img from B317 (latest stable for L12 at this moment) via MULTI-TOOL, using unbrick.
2.FLASH BOOT.img,RECOVERY.img via fastboot from given link - they are from L04 link, but my L12 booted and did the job.
(fastboot flash boot boot.img, fastboot flash recovery recovery.img)
3.PUT H60-L12C00B500 UPDATE.APP in dload folder in SD CARD - is the rollback file
4.BOOT device with 3buttons UNPLUGGED from USB and SD card UNMOUNTED
5.When u get installation screen MOUNT SD card As Far As Possible
6.After that PUT B317 UPDATE.APP dload folder in SD CARD(small pause at 19%)
7.REPEAT 4&5 steps


8. LINK hxxps://drive.google.com/file/d/0BzujZI5OEVIRWWxyLXNjRGNWb3c/view?usp=sharing
replace xx with tt

After that, you will have a working KK emui 3.0

Good luck.
