Hi. Just got my first brick ever. Just want to know why. New set, recently bought in Australia. Black N3DS (non-xl). Not used before, not even connected to the Internet until I started modding. Originally, at 9.9E. Downgraded to 9.2 using SysDowngrader. Twice, second time finished NATIVE_FIRM and restarted. Got back to home screen, open HBL, launched Decrypt9 and made a NAND back up. Restart again and tried SafeA9LHInstaller, blank. Restart and tried again. Got into the program. Pressed select, process started. "All check passed..." appeared. Normally it would go into another screen and start the installation. This time, just blank. Waited for 10 seconds, try pressing a button to turn off. No reaction. Waited for another 30 seconds, still no reaction so I held the power button to turn off. Trying to turn on again just blank screen, with or without SD card (screens are on, with power LED). Recovery mod doesn't work And before you ask: - No, the SD card is fine. Not corrupted. I've used the same card and files to install successfully on a few new 3DSes. - No, I didn't do anything stupid. Didn't drop it. Didn't touch it except the select button. It was sitting on the desk with charging cable plugged in. - Yes, safeA9LHinstaller is latest version, 2.5.7 - No OTP in the a9lh folder, safeA9LHinstaller will warn you about that I will be getting a hard mod to restore the back-up. Luckily I did it before that. So no, I'm not looking for solution, just want to know why it happened. Thanks. Update: entry point was browserhax. Hard modded and tried again, worked fine. This time I used ninjhax though.
