Guys please help...I think I'm also in a similar position. N3DSLL region changed to have English userface on 9.2. I tried updating A9LH. got, the the green success prompt, pressed Start to turn off device and now I can't boot it back up. Screen stays black after turning on, blue power light stays on though. Can't load into Hourglass...I tried the solutions for "black screen" cases here https://3ds.guide/troubleshooting but still no dice...If hardmod is the only solution, how do I do it?
