Hello, I'm posting this for help.
So about 4 months ago I turned off my s10+ and it started to auto-update, I forgot about it and went to sleep the morning after it would boot properly, I had the phone for 4-5 months prior and It worked fine with nothing more than a couple of small cracks and no damage. The issue was that It turns on for about 2-4 seconds and flashes the logo thingy then turn off I could still access all of the keystroke menus do all the resets and tests just fine so I knew it had to be firmware.
I tried installing many different firmware's and eventually gave up and contacted Samsung the representative said it was under warranty and had it shipped but when It arrived Samsung said it wasn't and said it had been out of warranty for about 3 months
I just today installed G975U1UES3DTDD on my phone via Odin 13 and It worked perfectly and About 6 hours later while I was skateboarding my music cut off, I tried to reset it and even reset the cache, To no avail as it started the same boot loop I was stuck in before.
I'm posting this as I have no clue whether I should reinstall? or if it will just do the same thing 7 hours later... I have no options left as Samsung won't help me even though it is a firmware issue with their own software and device...
Device info: SM-G975U1 Galaxy S10+ (Unlocked) with an ultra-mobile sim.
