Hacking Cannot boot into emuMMC after updating firmware in sysMMC

h00die · Dec 4, 2022

I updated Atmosphere, Hekate and sigpatches to get ready to update the firmware on both my sysMMC and then my emuMMC. I loaded into the stock sysMMC to update the firmware. After the update, I tried to dump the firmware in TegraExplorer and it failed with some error. I attempted to dump prod.keys in case I needed it (I have a copy on my computer anyway) but that failed too. Tried to boot into emuMMC and it gave another error, also stating that it couldnt write the log report to the sd card. I loaded back into stock sysMMC and it also said the sd card was no longer readable with Error 2016-0641.

I plugged my sd card into my system and tested if I could access the emuMMC on NxNandManager and both partitions are accessible and writeable still. This has happened to me twice now and I'm unsure what causes it, last time I gave up trying to recover it and started fresh, but I want to try properly this time. What can I do?

My sysMMU is updated and working fine. I cannot boot into the SD card or read it in the stock firmware. but I can access it, write to it, and otherwise in my PC, and recieve data about it and access part of it in Hekate.

I can't run daybreak because I can't boot into atmosphere on the emuMMC
