Bootlooping/Faulty display on Samsung Galaxy S5-G901F
Hello,
I have a spare samsung galaxy S5 that I use occasionally. It has been suffering from occasional random bootloops and shutdowns, I put in a new battery and it didnt fix it . However it's much worse now, and it can't advance any further than the initial samsung logo. It just gets stuck in an endless bootlooping cycle. I have researched hundreds of forum posts online about this issue and I can't seem to find an explanation nor fix.
A few posts suggested reflashing the stock ROM. The phone was an EE UK version, so I downloaded the firmware for it but I wasn't sure on the android version so I downloaded all 3 available versions (6.0.1, 5.0.2 & 4.4.4). I reflashed using Odin 3.0.9 and 3.1.3 as I saw that the odin version was important.
Only Android 4.4.4 allowed the phone to boot past the samsung logo and enter the initial setup menu, however, it seems that the display is faulty. Here is a video illustrating this: https://drive.google.com/file/d/1bKnQ9JB...
Is this an actual faulty display? One post I saw mentioned opening the phone up and checking the display connector, as it could be loose. The display was perfectly fine when it was working previously and occasionally bootlooping. I'm now stuck with whether replacing the screen would actually fix the issue or be a waste of money. Has anyone encountered this before and could offer any advice? Would it be best to sell the phone on as faulty and for parts.
Thanks!
