I can share my experience with i9082.
After tried lollipop (CM12.0, CM12.1, AOSP) i found it totally non usable for me as exchange mail is non stop generating errors and not working. Decided to return to Kitkat or JB.
Followed the instructions from first post:
Download the ROM zip -checked also MD5 checksum with Total commander to avoid errors in downloading
, btw, it possible only in IE, Firefox was showing empty page.
Put it on your ExtSD_Card - done
Download Recovery from(recommended) - Yes, Installed recommended Recovery
Enter CWM Recovery (volume up+ menu + power ) - done
Wipe data/factory reset - done
Wipe Cache partition - done
Format /System if coming from[KK] - missed it. My fault.
Install Zip from SD Card - Done
Wipe Cache partition - Done
Advanced > Wipe dalvik cache - Done
Reboot the device...And it's DONE
First times the boot will take a long time please be patience..
- Didn't noticed, was quite fast
So, please use common sense, check the checksums and use recommended recovery and wipe all needed partitions. Should work.
