To upgrade from 1.04 to 1.05, I downloaded the 2 files listed (STX40TAAD105_20090202.ecc & STX40TAAD-SAM40.ecc) from Toshiba's link http://support.toshiba.ca/support/ce...?docid=D000020
and put them on a FAT32 formatted USB stick. I followed all instructions to the letter, and I saw the expected screens, including the completion progress screen, and the last one which said to remove the stick and click 'OK'. I removed the stick and hit 'OK'.
It didn't do anything for about a minute, I kept hitting 'OK' and then the TV finally did a power reset (the power LED went off, then back on again). When the power LED came back on, all I have now is a black screen, and it will not respond to the remote, except for power on/off.
Then I went back and looked at the files, I saw that the first one had not downloaded completely, it was only 271K! I downloaded it from the link again (now 3.1 MB), put it on the stick and tried to start the firmware update again, but the TV doesn't recognize it, the LED on the USB stick comes on for only a split second during powerup, then goes out and stays out. I leave it unplugged for over 1/2 hour between attempts, same thing.
The firmware troubleshooting guide says “If current FW is newer than service FW version, it will not allow updating and no message box will appear (looks same as USB not recognized)”, from this Link: http://support.toshiba.ca/support/ce...W%20Update.pdf
Since I updated from 1.04 to a ‘bad’ 1.05, maybe the TV thinks that the 1.05 on the stick is not recent enough, and won’t allow me to upgrade it again? If that’s it, then maybe a hex editor to make it versions 1.06 or greater? I don’t know!
Can someone please help me rescue this TV? TIA, Al.
