boot 0 and boot 1 corrupted?

[_harry_]

During an update, my Switch got damaged. I’ve managed to boot it using TegraRCM + Hekate, but it doesn’t read game cartridges. When I power off the Switch, it won’t turn on either, and the only way to boot it is with TegraRCM + Hekate.


What can I do to recover it?
Any checklist?

Tried to explain it in the other thread. But i try to make a checklist, maybe to go through all options

1. Check your fusecount > knowing how "many" fuses are blown, you should know if it matches your OFW. If it is different, you might have the problem there. You can check the expected burnt fusecount with the firmware here.

2. How did you update? When you only use Daybreak and dumped firmwares known to be good, there shouldnt be a problem. I used to update my OFW first and dumped it with another payload/program. Then i updated my emunand with daybreak. If something really went wrong while updating, it should be good to have a nand backup somewhere...

3. Check if your game cartridge is working on the newest firmware you have right now. Could be emunand cfw 20.x, or sysnand ofw 20.x. Normally, the game cartridge slot can be updated by any firmware update. It basically has its own firmware

Note that hekate has an option called nogc, which prevents the cartreader from updating its firmware.
If you are on a newer firmware and have this option enabled, you will not be able to use the cart reader.
This features was added to be able to downgrade to a lower firmware again in case a super hack was found.
But that hack was never found so there isn't really any purpose in enabling that feature imho.

If you have an unpatched Switch and your Switch won't turn on without TegraRCM, then you probably have AutoRCM enabled.
When you power on the Switch, it will automatically wait for a payload to be injected.
You'll only see a back screen that is very dimly lighting up.
You can disable AutoRCM but then you need your jig and payload injector every time you reboot/start your Swtch.
With AutoRCM, you at least don't need the jig.
