Hacking Question Error while updating CFW manually on PC with ChoiDujour section 0 corrupt

ieatpickles · Mar 30, 2020

When booting into cfw through hekate, I got an error saying pkg2 not found (tried both emummc and sysnand). To fix this, I tried updating cfw through ChoiDujour manually on PC based on the Updating/Downgrading Manually on PC guide. While using cmd to convert the firmware files (Step 4 of the guide) using keys.txt file, got the error in the picture. Hekate and atmosphere are at newest version, cfw was updated to 9.1.0 before and was running fine until this happened

Choidujour was for older cfw's below 6.1. You can't update to 9.1 ofw with it. You have to use ChoidujourNX which is a homebrew app on the switch that you can select the new firmware and update right on the Switch. I don't really think updating is the first step you should take when trying to fix a boot problem though. You should fix the boot problem then if you want to update go ahead.

Unfortunately I'm not really able to help with your boot problem.

bump - i haven't tried updating but I also get the pkg2 error. I've tried everything including restoring a clean nand. Nothing helps

edit @JayMathis : looks like OP is using choidujour because they're updating using PC - they can't boot into the switch to try using choidujournx

I just did a quick google search and found this under Hekate on github. Not sure if it will help (I only used Hekate sparingly in the past and don't even use it anymore) but I figure it couldn't hurt to post just in case.

NOTE: You will need sept and a custom secmon and warmboot binary to boot 7.0.0-9.0.1 or stock emuMMC.
Warning: HOS 9.1.0 needs a new sept. If not updated, hekate will show pkg2 decryption error. On the other hand, hekate can still load older sept versions for 9.0.X.

I understand that but AFAIK you cannot update to anything past 6.2 using the old Choidujour. So it's not going to work.

You need the firmware files for the firmware version you want to upgrade/downgrade to. ... You cannot use files for firmwares 6.2. 0-8.1. 0 as the ChoiDujour PC application does not support these versions.

This is old and only talks about 8.1 but it still applies to 9.0+

Both of you should try update sept folder to hopefully fix pkg2 error.

I tried downgrading to 6.1.0 and the same error message popped up, and sept is on the latest version, updated through kosmos

Unfortunately updating sept was the first thing i tried

it didn't fix the error. maybe a new version will fix it
