Hey guys,
by the way, sorry if grammar is bad. Im German.
This is my first post here, so thanks for reading :)
I have already flashed some Smartphones with Recoverys, Custom OS an Kernels. So im not new to this.
Some days ago a friend gave me his G900F, because its stuck in bootloop after lollipop update.
I thought, thats no problem. "Just a new recovery with odin, flash kernel, clear cache and install rom".
At least ive tried like 3 kernels and some roms. everytime the same thing: bootloop.
Thats totally weird for me. i cleared all caches, davlik, internal storage etc and its still the same.
Bootloop:
Sometimes it boots up till Roms "settings screen for first boot (language, wlan etc)".
Then after a random time of seconds, i get graphic errors on screen and touch stops working. (parts of screen are flickering or swiched against each other).
Then the reboot follows with 2 short vibrates as confirmation. And sometimes it reboots before it reaches the Rom.
For me it sounds like broken hardware, but in recovery mode it works normal for hours, inclusive graphic gui and touch o_O
The Recovery needs the same hardware parts (like cpu, ram, touch, gpu) to work like the os, doesnt it? im confused. Bricked or not?
Thanks very much for reading my Thread :)
