Not working on first rg350

[NelEctric]

I've installed the latest v2.0 version on my rg350 and I only having a black screen. I can exit with power+select. I've tried to install previous versions, not works. Then installed again 2.0, not works.

I've checked the file config.json in order to check the routes to my sdcard, everything seems to be ok. I've algo copied the pymenu config folder from other rg350 with Rogue firmware (working) to my rg350 and still happens the same.

My current firmware is the official one with the hdmi patch, I've also tested it with previous stock firmware, same results.

Any suggestion, please?

Thanks!
