i'm posting on behalf of a friend of mine. He has a i9505 that suddenly stopped working. He told me the phone would randomly shut off completely for no reason. I took a look at it today. On boot the phone would display the kernel logo distorted (vertical lines) and the WHOLE screen would turn green. This happens only sometimes however. After displaying the kernel logo the phone simply shuts off. Even in the recovery it would suddenly reboot. And the a blue led lights up sometimes.
I've never owned a samsung but i have the phone here with me (LG/Sony user ). I went ahead and flashed I9505XXUGNF1_I9505OXAGNF1_I9505XXUGNF1_HOME.tar.md 5 in Odin. Flashing went okay, the problem persists.
Btw, knox is 0x1. My friend told me he only did a factory reset, never rooted etc. Can't comment on which version of android he had before.
Can someone help out?
