Hacking 2DS gets stretched screen and can't boot HBL

[Duckmaster]

Hello everyone, sorry to bother with my problem

So I followed that tutorial on YouTube :
For my 2ds. Everything was flawless till the SysNand Restore (keep a91h) part. It triggered an error (non existant file), I rebooted and did it again and it worked.
However, I couldn't inject H&S (same error) and now the top screen of the 2DS stretches away from the screen, I can only see half of it (except on the web browser).

If I remove the SD card, the 2ds doesn't boot.
If I try to use soundhax or the web browser to boot HBL, it freezes the 2ds.

I'm convinced Luma did install (I can hold R or start during startup, it does send me to Luma or the Hourglass/Luma/Decrypt9 choice), but I can't check the system version in the system settings anymore as the screen is stretched.

2DS is ver 10.3.0.17EU

Can somebody help me please ? Thank you

EDIT: 6/1/2017 : Solved !

Your first problem is that you followed an outdated video guide, when you should've only followed http://3ds.guide. The stretched screen on 2.1.0 is normal on a 2DS, as the firmware was never made to be available on that system. A stretched screen on any other firmware, I'm not sure of as I've only seen the issue on 2.1.0. A system not booting without the SD card in is normal for Luma because it doesn't recognize the payload on CTRNAND (because there is none). As to what you can do from here, I have no clue.

Thank you very much for the fast reply.

Is there any way to go back ? Or do I need to do a hard mode in order to do so ?

I wanted to try using that tutorial you just linked, but whenever I try to boot HBL using soundhax the 2DS freezes...

It sounds like you are still on 2.1. Try the NAND restore again and make sure it's successful. If you still have a stretched screen after that, you most likely made a NAND backup while on 2.1 and it overwrote your 10.3 backup.

If you do what Jdbye said and still have a stretched screen, follow https://3ds.guide/9.2.0-ctrtransfer except use the bin file not firm file for GodMode9.

You could also follow https://3ds.guide/a9lh-to-b9s and then follow the above as written.

That solved the problem and fixed everything.
Thank you so much !
