A1502 820-3536A working, but turns off after about 30 minutes

Should I also do a reinstall after flashing the new one?

though I might have to do this anyway as the new EFI probably has no APFS support…

So okay got this done. Bt apple services are still an issue. Well at least FaceTime and iMessage. I tried both my old install and also a fresh install I put on an external SSD. What happens is with iMessage I can sign in like normal but after like 10s I get thrown into the login screen again... For FaceTime it does a similar thing where I log in but it just goes back to the login screen. In terms of stability, I can't really comment on it but it seems fine for now. Oh, and I did a PRAM reset.

Should I post this in a separate thread instead?

Okay issues are sadly still there. Machine occasionally just turns off while using it and after a night in sleep I once found it back on the login screen after a reboot. No error messages though...
