The computer now no longer recongnizes it as a kindle touch (or anything) and I tried to use MfgTool to fastboot it, but it brings up the message "failed to run command: type = "boot" body = "Recovery" file = "fastboot.bin" timeout = "10" onError = "" text = "Loading fastboot u-boot to device." The handle is invalid., Error code:6"
Same message appears when I use MfgTool to try and boot into main or diags.
Any help would be awesome! Thanks ahead of time!
I sounds like your MfgTool profiles may be messed up, so that MfgTool cannot find the custom u-boot images. Try downloading it again before retrying.
Or it could just be a "Windows problem" that fixes itself by rebooting your windows host PC (or VM).
