60D -bricked?

[myaddib3]

Hello! I'm here to ask for help. I installed ML on my 60D, and for a while (one hour) everything was fine. Then I took out the ML SD card to run the camera without ML, put in another SD card, the camera didn't run, and after that the camera would not turn on no matter what I did. The only sign of life is when I put in the SD card with ML, the LED indicator lights up and does not go out. Nothing else happens.
I tried all the tips from here https://www.magiclantern.fm/forum/index.php?topic=2221.0 and it didn't help. I also took the camera to a local service and they said there was nothing they could do except change the motherboard, but it is too expensive for me.
I ran some diagnostics tools. Display and LED tests are working. I can send ROM files if anyone would be kind enough to give them a look. This camera has a lot of sentimental value, so if anyone has any information or suggestions- please help.

Let's take a look. If you were able to run the portable ROM dumper, that's a good sign.

Hi again! I apologize for answering after such a long time! I uploaded the files to a google drive, didn't figure out how to attach them here:
