My FLU converted to 2700 keeps rebooting. I tried reloading the latest file twice but to no avail. Do I need to JTAG it? Actually, I mistakenly unplugged the coax while I was doing a TP scan. It never came to the menu screen afterwards..
If you unplugged the coax with power on, you might have damaged the switch. Otherwise, the best thing to do is to reinstall the b75 boot and then add the 253 conversion bin of your choice. If you can't do that, do a revert to 2500 procedure, then 294T BIN under boot 600 and then reconvert. These receivers can take a lot of abuse.
