My feedback:
Originally had stock J015 -> No issues other than stock browser giving WLOD on WIFI and random unable to charge/boot unless using a cheap charger.
I:
- Reset phone back to original firmware via SEUS.
- Flashed kernel from package via FlashTool and installed xRecovery
- Installed ROM via xRecovery
- Had 2 x WLOD while allowing phone to boot and settle.
- Everything seemed to work fine other than WIFI forgetting my hidden network.
- Booted back into xRecovery and flashed gapps zip from package
- Now get WLOD using standard browser on both data and WIFI, WLOD when opening GMail on both data and WIFI, WLOD when installing APKs using flashtool, FC using YouTube and phone feels hot.
Other than that the phone seems quite responsive, I can live with all bugs but the GMail WLOD as I need my emails

So far seems slightly less stable than J015.
Will run some more tests and give more feedback once its been used a bit more.
Keep up the great work guys, wish I could help more!
Oh, and I've attached my logcat in case it helps in any way.
EDIT: I now seem to be getting reboots! As soon as the boot process completes it dies (no wlod)

Does this about 4-5 times before I can use the phone, then does it again a few mins later...
I have attached another logcat but doesn't seem to catch anything usefull... are there any other tracing tools i can use?
2ND EDIT Just tried to make a call, got WLOD but the call continued.. i could here the answerphone but couldn't hag up.. had to pull the battery.
Think I'm going to flash back to original.....
