Hacking Question Can't boot in OFW except when using Hekate

[Autrui]

Hello,

I followed this guide in order to migrate my emuMMC on a bigger sdcard.

I'm not sure what went wrong, but I can't boot my Switch normally on OFW. Nothing happens, no light, just a pitch black screen. AutoRCM is disabled. I can enter RCM and send a payload, and when I'm in Hekate, I can boot the OFW from there, everything seems to be working fine.

I don't really understand what is happening and I'm looking for an explanation of what went wrong and how to fix this.

Can you help ? Thanks !

Edit :

Problem solved doing a MMC repair following this guide.

The only reason i can think ofw firmware would boot from hekate and not normally is a fuse mismatch.
Try holding power down for 20 seconds and reboot. Have you ever restored an old nand backup?

No I didn't restore NAND backup !

The OFW version is up to date to 10.2.0, and Hekate says I have 13 - 0 burnt fuses.

emuMMC version is 9.2.0|AMS 0.14.4|E

AutoRCM is OFF.

I can't boot my SysCFW either. I posted the error on github and received this anwer from SciresM :

A partial update was improperly performed.

To fix, try manually flashing latest package2 to MMC.

Can you help ?

I did a MMC repair following this guide. All went well, I can access my OFW booting normally and from Hekate, I can access my sysCFW and my emuCFW. Problem solved !

sorry for necro posting, but using the reboot > OFW in hekate fails for me, i was also pulling my hair out on this as i was getting nothing but black screens. however i noticed that "launch > OFW SYSnand" works fine. note "OFW SYSnand" can vary based on your hekate_ipl.ini
