Hacking Question Help, trying to unbrick 6.1.0

[Sucuk60]

Odd, you're the first person I've seen with that issue. No one else I know who's done this has had a problem with the exfat support

When I tried it with exfat support Choi didn‘t give me the FS-510 file for booting up the system via Hekate.

Tried to use gptrestore and after used ChoiDujour110 —noexfat ... , same thin, still stuck on switch logo

you tried to manual downgrade to 6.1.0 right ?

Can you try to manual downgrade to 5.1.0 instead ?

No, I got the switch like this, I'm trying do "revive" it, I'll try do downgrade but what about the fuses?

Say, if you successfully "manual downgrade" it to 5.1.0.
You will not be able to boot in up normally (because of fuse mismatch)
But you can boot it up in atmosphere or other CFW (because the CFW skip the fuse check)

You just have to downgrade it with Choi. After that you need to boot to ofw/cfw with hekate

Done the same process to OFW 510 and when I do Launch -> FS_510-exfat_nocmac_nogc I get "Failed do launch firmware" on red letters

Are you confident that you followed these steps exactly.

If so, well, in this case I have no idea.
It could be that your PRODINFO and PRODINFOF are broken / corrupted ?

One more thing.
Can you calculate hash on the generated NX-5.1.0_exfat folder ?

Do you get the same files with me ?

 

[Lazardo]

I've used the guide "How to install/run ANY Switch firmware UNOFFICIALLY (WITHOUT burning any fuses)" from gbatemp, which software do you use to calculate the hash?

 

[PrEtZaL]

It won't be anything to do with that, you could potentially have a corrupted fs. You can try mounting the partitions in hacdiskmount and formatting the using guiformat making sure you select 16k cluster size. Do that for the user and system partitions, then copy over files created by choidujour as before.

Just tried that and got the same result

Just used the guide and got a blank screen when I get to
11. Return to the main menu, then select ‘Launch > FS_XXX-exfat_nocmac_nogc’ where XXX is the firmware version you downgraded to.

I used 7zip.
Right click on the Choidujour generated 5.1 folder and CRC SHA >> *

Try using hekate 4.6 with the accompanying boot loader directory

I'm starting to suspect the person you bought the sw itch from did something stupid

The checksum is different (I think it should be, the contents of the boot* are made from different keys),

What strikes me is the different number of files and total size.
Using hekate 4.6 didn't help
When I bought the switch I knew that it was bricked and the previous owned wasn't able to repair it... I just don't know what.

Can someone (if it's permited) post the output of the "Print emmc info" from hekate? (please mask the serial number), I want to compare sizes and check the partition type.

(btw thanks to everyone that tried to help me so far)
