Hi, I used ChoiDujour to update my switch from 5.1.0 to 6.2.0, after I did that it worked fine. But then the system crashed, and I had to power off, after I powered off it doesn't load up anymore.
I tried restoring my boot0/1 backup but that doesn't do anything. How can I fix this?
Also I removed autorcm and booted to stock, but a blue screen comes up.

You need to dump your boot1 and 2 again

Can you please let us know what you did and the steps to get it working again? I want to do some stuff on my switch and if I run into any issues, I would like to learn and get as much information as I can, if you don't mind to share.

Thanks and Happy Holidays!

Most certainly, I'll document what I did to fix it once I get home.

Does the switch autoboot to emunand without RCM? I thought you still needed to launch a payload first.

You do need to launch the payload to go into the emunand. But if you only update the emunand and leave the sysnand on it's original firmware, there's no problem if you accidentally boot to sysnand as it's version would match the fuse count so it wouldn't burn anything.

Hello !

My switch was till a few hours ago running fine on FW 6.1 and SX OS 2.4
I wanted to install the FW 7, so, following https://team-xecuter.com/community/...ine-nintendo-switch-with-choidujournx.128170/ I used ChoiDujourNX 1.0.1 to install firmware 7.0.1 (i've checked the zip checksum).
Everything went fine until reboot.

Actually, the switch didn't reboot. Now I can't start it in a normal way. When I use the SX dongle and tool, I can access to SX OS menu but :
- If I launch Custom FW : black screen
- If I launch Original FW : black screen
- Only the settings tab seems to work

Do you have any ideas on what's happening ?

Thank you a lot for your help

Thank you a lot aerios169, it worked !
The thing I don't understand is that as the start of the process, I put SX OS 2.5.3 at the root of the sd card _ I thought it was compatible with 7.x firmware family, isn't it right ?
Anyway, after reading your answer, i switched to SX OS 2.6.2 beta, and everything went fine.

Thank you again for your quick reply
