Hacking Black screen on boot (o2ds)

[glebanych]

Hi. I got the new o2ds yesterday and it was on 11.6. I did the seedminer trick (thanks for all the guides, this is awesome), installed freeshop, downloaded couple of games. After that i decided to put ~10 games in queue to download in sleep mode. So 7 hours later i can't boot into home screen, all i see is black screen. I can boot into Luma and Godmode. I also tried the 3ds.guide Troubleshooting ("Black screen on SysNAND boot after Installing boot9strap" section), but it says that i should be able to boot into home screen without sd, but i can't.
Do i have any other options? Thanks.

1. Do you have a NAND backup? If so, restore it.
2. If no, try booting into recovery mode (A+R+L+Up) and updating.
3. If that won't work, try CTRTransfer via Godmode9, Decrypt9 and last option would be Lazarus3Ds.

Hmm, so i just turned it on, didn't touch it and after about 30 minutes i heard a home menu music and yeah, it finally booted. What was that?
I also tried recovery mode option before that, but all i got is a message that my system is running the latest firmware version.
Anyway, thanks for your help!

P.S. Also about NAND backup (i think i got it, but just to be sure). I followed all the steps on 3ds.hacks.guide so i got xxxx_sysnand_000.bin, xxxx_sysnand_000.bin.sha and essential.exefs after using Scripts - Backup SysNAND in GodMode9. Is it all i need for a backup? Thanks again.

Yep, that's all you need, so store it somewhere safe.
