... have never tried any of these ROMs/files ...
I have used this 3.13 ROM a few times, and just the other day. For the first time
(the other day) I also saw a recovery/repair screen come up, saying that the flash
failed, and I was a little worried also. I tried the flash again, and the same thing
happened. Unfortunately I do not remember what I did to fix it, I might have run
e2fsck, or I might have just exited out of that shell prompt. I would first try
just exiting out of that shell, or doing whatever it said to cause an automatic reboot.
In any case, it booted up fine afterwards, so there is hope. If you are are a newbie
or scared, I would not mind repeating the flash, and getting the details, assuming
it happens again. The only thing I did that I can possibly think might have caused
this, is I tried the OZ 3.5.4 GPE release that uses altboot, and I was playing around with
installing OZ to an SD card. I then decided to reflash SHARP 3.13 again. I am
doing this on my "extra" SL-5500 which has an audio problem on 1 channel, and
I do not use the unit very much, which is why I don't mind trying the reflash if
you want me to.
