Hacking Question I think I bricked my switch

[Tinkerit]

Hi everyone!

UPDATE: thanks everyone, the issue was indeed that the path was incorrect (and also I didn't concatenate my files properly).

Everything is now back and working in 1.0.0

Great, and thanks again everyone!!

TL;DR

00: rawnand.bin (0000000-3A3DFFF)
Filename: Backup/e544439d/Restore/rawnand.bin
Error (4) While opening backup. Continuing...
Time taken: 0m 0s

---

Fuses burnt: 1
Model type: retail
AutoRCM mode activated by ChoiDuJourNX
Software version: 5.1.0-3.0 -> 3.0.2-0.0 (ExFat)
CFW version: RajNX edition v0.7.5.1
Full eMMC backup: 1.0.0​

First of all, a quick thank you to the community for the great tools created, I have spent a lot of time reading before joining.

I have a retail 1.0.0 switch, on which I have installed SX 5.1.0 with ChoiDuJourNX. Everything worked fine except that my SD card was in FAT32. I am pretty confident that I chose the ExFat version upon installation, but because the SD card was only ever recognised by the switch when in FAT32, I tried to downgrade (to 3.0.2-0.0 ExFat) to be sure that I did have ExFat with ChoiDuJourNX (keep in mind that I still have only 1 fuse burnt, and I checked this with hekate multiple times, it is still the case).

However, ever since I did this, when I try to launch the firmware with the Launch Firmware option (RaJNX CFW - PreventGCUpdate), it gets stuck at this screen:

Note that I can still boot in RCM mode (in fact, only in this mode because of/thanks to AutoRCM and ChoiDuJourNX), and that payload injection (tested with hekate and RajNX) still works.

I have a full eMMC backup of BOOT0/1 and RAW GPP of my switch before I did any of these modifications (so software version 1.0.0), but when I try to restore it, I have the above Error (4).

Does this mean that my backup is corrupted? What can I do?

Sorry to hear that. Other experience members are sure to come to offer you advices, I just want to say that I have heard a lot of brick stories when trying to get this ex fat support unofficially. Why does people keep bothering with this?

Thank you for your understanding. Remember that this is all done with full knowledge of the risks involved, and there were a lot of disclaimers that things could go wrong.

As for the reason why people go through the trouble of getting ExFAT support is to lift the limit of 4GiB for each file (at least that's why I did it). This is useful when loading backup games that are usually (mostly) a single file (.nsp).

try to use reinx hekate and rajnx doesnt want to boot for me on 3.0.2

--------------------- MERGED ---------------------------

And delete fs_mitm.kip located in ReiNX/sysmodules folder

He actually mean that why people bother to stay at low firmware. Might as well update officially and still able to play pirated games. This is too troublesome.

Actually you can avoid ChoidujourNX by updating offically and install autorcm. You would not burn any fuse.

Thank you for your suggestion, I will probably try that. What is this fs_mitm.kip file? It looks too similar to Man In The Middle for comfort.

While this is true that staying at a low firmware may also prove useful, I was just saying that it is important to be on ExFAT in order for large files to be on the SD card.

doesn't it reboot the console after installing the firmware officially?
I've read warmboot does burn fuses, but I still haven't read proper information about it. it's still blurry what warmboot is/does.
if warmboot is just a full console reboot (and not a bootloader launch), then you can still access RCM, but you don't have to miss the button combo on auto-reboot, right? or else it would launch the bootloader (skipping RCM) and burn fuses.

when update officially, it deletes auto rcm because it overwrite boot0/1.
after update, it auto warm boots or not? is warmboot like a coldboot or a bootloader launch?

What backups do you have and what are there system versions ?
Did you backup boot0/1 for the system ?if so what version ?
For hekate to restore the rawnand file i still believe that the sd card needs to be formatted to exfat...
Hekate reads and supports exfat, and dont think it reads fat32 when restoring..
format your sd card to exfat transfer the same folder structure
Backup your boot0/1 if you have not already

Format to exfat
then sd card should appear like this

Backup/e544439d/Restore/rawnand.bin

then hekate will restore...

1 fuse burned ? then restore 1.0.0 rawnand.bin..
then start the choidujournx to 5.1.0 with exfat support if you wish

But would risk going online with cfw and maybe flag himself for ban...

Error 4 is file missing. Check the path and you will see that it's in /backup/<emmc sn>/restore/

Thanks Canna for your suggestion, I have actually already tried formatting the card to ExFAT but had the exact same result.


Oh yes bundat, it may just be that... I have everything in Backup, but nothing in Restore. Let me try this new folder structure and update you. I feel very silly I didn't think of that myself.

yep goes in the restore folder showed that in my post


did you backup boot0/1 ?

Sorry I didn't see it in your post Canna, I was just focused on ExFAT.

Yes, I did backup BOOT0/1 but I am not sure it would be a good idea to restore them in this case. I am afraid that I find myself in the situation that @Cyan described earlier, where if I fail to enter RCM mode I burn my fuses.

One more question about the directory structure: I currently have 15 binary files (rawnand.bin.00 up to rawnand.bin.14) and not just one big file. Should I concatenate all files together in rawnand.bin? Is there any separator needed or would a simple cat command (in the correct order of course) do the trick?

check out my guide for combining

Check this section out For Fat32 users only >>FAT32 Mini Guide

then place the 1 rawnand.bin file on your Exfatted sd card

Backup/e544439d/Restore/rawnand.bin

Can be avoided when you restore with hekate just simply run the auto rcm on hekate before you restart this will apply auto rcm to that boot0/1 you restored

But in your case your restoring the system version with the same fuse count of 1 so you wont burn nothing or your house down

Actually that is what your guide does, just using the cat command :-)

If you restore a rawnand backup, you also need to restore boot0/1 backup that was made at the same time.
If you have a different fw version rawnand from your boot0/1, it seems that will actually brick you.

You needn't worry about burning your fuses if you successfully restore a 1.0.0 backup of your rawnand and boot0/1 anyway.

That is very true. Thanks a lot.

Thanks @Stilu2k6, but unfortunately I do not think that this video is linked to my specific problem. However, I do not have a lot of hardware knowledge, so I may be wrong (one more reason to avoid doing what was shown in the video myself and with no help). Nevertheless, I appreciate you coming to my help
