Yes, it is my own fault. After hacking several consoles successfully I just turned lazy and skiped backing up NAND.
I'm not sure if it's a brick, but after transferring the console simply won't boot. Payloads still work fine. I'm trying to change region from US to EUR hence the 9.2 transfer after installing A9LH.
2nd attemp, still won't boot. There's nothing wrong with either the SD or the CTR files, because it worked before on another console.
