MACBOOK PRO EARLY 2011 13 LOGIC BOARD FAILURE BLUETOOTH

I have tried the Apple Hardware Test via Internet Recovery Mode at multiple stages. There is another kernel panic report indicating the same last loaded and unloaded kexts (also in single user mode). Interestingly enough, the kernel panic would come up at this point during boot more than once. System uptime in nanoseconds: 78011217698 This is one of the kernel panics of a crash in single user mode. At no point would I get a startup chime or the three beeping sounds that can indicate a failed boot. Booting in safe mode would work relatively consistently, however, it would still sometimes crash and after crashes or trying to boot it regularly, it wouldn't turn on for a couple of times (usually two or three) even in safe mode with only the white indicator light repeatedly blinking three times in a row. After that I wasn't able to boot it normally anymore. RB_RPTR: 0xffffffff, RB_WPTR: 0xffffffffįollowing this the Macbook would turn on again and continued to work for about a day, however, at one point after putting it in sleep mode it failed to shutdown and ran for an hour in my laptop case running considerably hot.

I later found a couple of Kernel Panic Reports that indicated a GPU restart 4 times with 10 seconds apart the heades of which looked like this: Tue Jun 19 15:10:16 2018

It worked fine for a while, but about a week ago it randomly shut down again. I send it in to a third party repair shop to replace the GPU. However, about a month ago it died again with the same symptoms. Since at the time Apple's repair extension program was still in place, I got the logic board replaced for free. In 2016, my Macbook first showed signs of a broken GPU. I have a 15" Macbook Pro from early 2011 and am trying to figure out whether the logic board is broken.
