So. Basically. Today my S7 edge started crashing after the Samsung Logo.
What I did was flash the stock firmware to restore the stock ROM after coming from a custom one. I'm sure I did everything correctly, flashed the 4 parts of the firmware via Odin correctly and it even showed me a "PASS!".
After it succeeded and rebooted though it crashed while performing a factory reset. Then I tried to boot it into the recovery by myself and it kept crashing while saying "Erasing."

I'm out of ideas. Should I reflash? Or might it be a broken motherboard?

When it says erasing how long did you wait? You have to wait like a minute or two to get the recovery menu to show sometimes right after flash. You flashed with CSC right and not home_csc?

If you want you can try flashing custom recovery and manually formatting the /system and /data partition then flash again and try booting it again.

Thanks for the reply.

I always give it time. But it crashes even at the "Erasing" screen. Like... It boots up. Gets into that screen and crashes after 2 seconds. It doesn't even reboot.
Yes. I always flashed CSC. Not the home one.

I'm not sure if a custom recovery like TWRP would help because if the stock one doesn't work, why would TWRP work?

Had this exact issue before on a S8, could not fix it.

Sometimes it could be just the battery needing to be replaced or every connection to the logic board needed reseating. PITA to diagnose as you have to take the rear glass cover off, done by using plastic flexible thin cards and a razor blade to initially lift up the glass edge a bit to slide the plastic thin card to separate the adhesive.

Yeah. Your phone is showing Samsung logo white text splash screen, then goes off and reboots 10 seconds after right? That's what mine did.
Mine doesn't always reboot. It just turns off. The reboot mostly happens only then after I tried to access the recovery.
