Hacking Question Stuck at 5.1FW

[Slumpolo]

Hi,
I tried to update my switch to 8.1 using choidujor from SX OS. After that my switch doesn't boot anymore and I tried everything.

I follow the manual update guide and now my Switch it's on 5.1 firmware. If I try to update to 8.1 or 9.0 from SX OS or Atmopshere using choidujor I got error 2002-4314 and to boot I must back to 5.1 via manual update.

I tried to update switch to 9.0 using regular update process and I got same error.

I tried with several MicroSD both extFat or Fat32.

Seems that my switch can't go over 5.1 firmware.

Can it have anything to do with the number of burnt fuses?
I got this: (ODM 7/6) : 11 - 0

Anyone can help? How can I update to 8.1 or 9?
Thank you

No, the number of burnt fuses only determines what lower firmwares you can't run. Higher ones will work regardless of fuse number but will burn your fuses.
Updating your firmware is always recommend to be done through atmosphere.
Have you tried entering maintain mode and updating from there on?

Maintain mode by pressing power one, volumn- and volumn+ at the same time?

Yup, see if it makes a change for the better.

No way same error
I made some step.
1) Update from 5.2 to 6.0 ok
2) Update form 6.0 to 7.0 ok
3) Update from 7.0 to 8.0 or 8.1 I got 2002-4314 error
Any idea?

Maybe something wrong with your 8.0 / 9.1 files?
Did you tried to download the update files again?

+1 to this.
Did you get your 8.1 firmware from a certain "dark" website?

I got FW from a certain dark website... chudojour said that the fw was correct. I tried also with a 9.0 from another website... same error

I tried with a 8.1 FW from a different source... same 2002-4314 error
