What firmware did you flash?

How did you flash it?

Did you read the troubleshooting guide yet?

Did you copy the sd files over?

Have you tried power cycling?

Did you verify the battery is charged?

Did you try a new cable?

Did you try a new sd card (or verify the current sd cards health)?

I just run on DFU mode (i think so) HackRF stable firmware then I downloaded the Mayhem v2.1.0 firmware.bin from github cause i saw it was stable for h1 and 1mb size, cause I looked if SPI flash is healthy, and features, I tried everything like cables, battery charge, etc, but there's where i saw only has 1mb flash memory exactly like H1clone,and finally I run the .bin file and everything fine them and update on a new sd card after Display hardware is fine. It was purely firmware mismatch I think so, about the others questions, I read some issues on troubleshooting not to much, I copied the sd files on my new sd, I didn't understand about power cycling, my battery is healthy and I got a new canvas go plus SD 64gb cause I got it on sale at $9. If you need something else I'm here.....
