Stuck at boot logo
After upgrading to 4.3 via kies i m stuck on boot logo.
When i entered recovery mode there was a fallen android with a red triangle
Factory reseted still the same.
Tried many odin 4.3 roms (stuck at boot logo again)
Flashed a custom recovery twrp which flaggd knox and flashed alliance rom 4.3 (still stuck at boot logo)
Flashed boffela kenerl (still stuck)
Flashed a 4.1 custom rom
It worked but no imei did a efs restore nothing happened
flashed persus kenerl (imei and signals back)
Lastly used 4.1.2 for some time
tried to upgrade to 4.3 again (stucks at boot logo)
flahed twrp some how i cant wipe data and encryptions says unknown file system
Now using 4.1.2 alliance rom 1.3 (Note all stock 4.1.2 roms work but every custom rom like cm,omni rom, miui dont work i.e they stuck at boot logo too and already tried factory reset)
I have 2 questions
what does fallen android with a red triangle in recovery mode mean ?
Also what about the twrp issue?
Any help will be appriciated
