Right. So you’ve attempted to format it, using a fresh v0.5 image. I’m just going to assume you’re using a stock v0.5 image, although if you’re mainly gaming on the device, I highly recommend my image that I’m maintaining here
I’m assuming you’re using the same SD card as before. Some counterfeit cards are listed as some size, and sell for cheap; when they’re actually only a 2GB Card relabelled and with their header changed to say they’re 256GB or whatever.
Now for some trouble shooting.
- How are you going about flashing the image?
- What version of etcher are you using?
- What OS is your computer running?
- Did you decompress the file to have an .img file ready to write?
- Did you wait for the image to be fully written before ejecting the card?
- Did you eject the card properly?
- Did you have power connected to the gameshell during the initial boot up?
- Did you wait even during some black screens for the gameshell to properly initialise during the first boot? (Takes about 60 seconds, vs standard 30 second boot time)
- Have you tried doing it again?
- Have you checked to see a cable hasn’t come loose when you ejected the SD card? They are very prone to doing so.
Hopefully following that should get you up and running again.
If it still doesn’t start up after flashing a new image, check out this thread.
