Issue: System wont boot (not normal, not luma, not GM9) Symptoms: blue LED flash slowly once when I try to power the system (regardless of buttons pressed/hold) Reason: Replaced boot.firm on CTRNAND manually with boot.firm from root. Sys ver: 11.4.0-37U Luma 7.1 GM9 1.1.2 (I think) I have recent NAND backups I recently bought a N3DSXL with CFW on it and assumed it was running A9LH since it had Luma 7.1. It had been reset so no icons, apps or anything on the main menu. I tried following the A9LH to B9S guide but got stuck at step 16. Instead of luma chainloader menu I got GM9 menu. Here I had a brainfreeze and thought I could copy the boot.firm from root to CTRNAND. after this the GM9 had a yellow bar on top instead of a green one (which I should have reacted to -.-) and I powered off the device. Is there anything that can be done about this? Any help is appreciated.
