You can try a 'RescueStick'. Here I have one for the '540, that can be adapted for the '542. Extract the zipfile to a (fat formatted) USB thumb drive, replace the ras.bin file by the <firmware>.bin from a 542, and adapt some textfile to have the right md5 sum of the new ras.bin file. Plug the thumb drive in, and boot the NAS. If you are lucky, it will reflash the firmware and cure the problem.

Yes, I can. But I have no way to test it, so it's only best effort.

According to this lines you used a firmware file of the '540 (B103). Did you exchange the ras.bin? And your board is a '520. (B203). A 542 is a B403. Are you sure you have a 542?
