Note Edge not booting up

[HatsuneMilku]

Hi there, the Note Edge (N915FY) won't boot up the operating system and won't enter recovery when there's a SD card inserted.
When I remove the SD card I can enter recovery and also access the SD card's files when I put it in after booting into the recovery. I somehow managed to flash cwm recovery on it.
I tried to flash lineage 8.1.0 but it fails with error code 7.
I will try flashing twrp next and try flashing lineage again.

Edit: I successfully flashed twrp 3.1.0. I will try flashing the 3.3.1 IMG from their website for tblte.
I think this some has some kind of hardware damage. Sometimes I can boot into recovery just fine, sometimes it stays on this booting screen, sometimes the screen just turns off. Then I have to take the battery out and put it back it to be able to start the phone again.

Edit: I successfully flashed twrp 3.3.1. now the phone boots into twrp without any problems, even with SD card installed

Edit: after freezing the phone at -18°C it works for some minutes just fine, so I assumed that I have to reflow it.
After reflowing the MMC it's working fine.

Hi, how did you reflow it? Oven or pro job?

Am currently using the shim mod, and working fine, but am looking for a more permanent solution.

Thanks
