ReplyDeleteYour device details?
Deleteindex cloud zest lolipop5.1 build number intex-cloud-zest-v02-ser
ReplyDeletekernal version 3.10.65+
spreadtrum sc7731
recovery twrp 2.8.7.0
Well i've already said i dont have spreadtrum and never worked on it. so i cant tell you exact solution for it.
DeleteMaybe first make sure the rom you are porting is uses same kernel version.
try fixes from this guide.
and maybe take a logcat.
Sir, Can I use this to Flare J2s SC7731 (running 6.0)?? I want to make Leagoo Z5C SC7731 (running 6.0) custom rom...
ReplyDeleteYes this guide is for spreadtrum chipset.
DeleteXolo era x twrp touch problem

Delete/system/etc/gps.conf
boss how about big screen im porting from 4.5 inch screen to 4 inch
ReplyDeleteScreen size doesn't matter that much.
DeleteForget about screen sizes(4, 5, or 7 in.), the important is screen DPI(pixels destiny) or in simple words resolution. you can port rom from tablet or devices that have bigger/smaller screen sizes.
just make sure you dont port from a device which have 1080p display while your device have 720p.
higher resolution to lower resolution resolution or lower to higher can be ported but not all roms boots up.
boss how about stuck in bootlogo not bootanimation ported idos rom still stuck at bootlogo please help
ReplyDeleteWhich you are trying to port. Is it same chipset, kernel version, Android version? Try these
Delete- libandroid_runtime.so
- libandroid_servers.so
- libmedia_jni.so
- Repack boot.image
- Fix Storage
if stuck in the starting apps
ReplyDeleteAfter a nandroid try:
Delete-fix permissions through recovery
-wipe cache and dalvik cache through recovery
-Wipe data (NOT sdcard).
-Factory reset
If this doesn't work the problem is what's installed to /system..and we'll go from here.
