PS: Although better to use the same version as on the unit for total safety, i've never had a problem using a later version's boot component for that task though. It's quite likely to be a concern if you use an earlier boot/ldr bin to try loading a later [i.e. larger] fw_all.bin though.
@Neil
Would you be so kind to upload 6.40 /the whole FW/ in order to flash it as the last attempt prior to declare the unit dead?
All other attempts - loading higher or lower version of FW, cure FW, SD card commands (thank you Loly) failed.
