Hacking Question Cannot boot into emuMMC after upgrading kosmos to 15.3

[gerrardx]

Hi,

This confused me a lot. So I want to ask if anyone know if there is a solution except recreating an emuMMC.

1. Previously, I used kosmos 15.1 and created emuMMC with FW9.1. That was my first CFW on my switch.
2. Today, I want to update the kosmos to 15.3 in order to upgrade my emuMMC to 9.2.
3. I removed all the files except Nintendo and emuMMC folder on the TF card and copied all the kosmos files and kosmos patches files to it. Also updated the payload file in the RCMLoader
4. After several logos, it got stuck in the black screen.
5. I can still boot into the emuMMC if I switched back to the 15.1.
6. I can boot into the sysCFW with 15.3.
7. I tried to use TegraRCM on the pc. The same result.

Any suggestion is welcomed. Thanks

How is the SD card formatted?
