My 860 suffered screen damage - still working, but....
So I got a 3100 from Pricejapan. Wow that came quickly.
When I went to install pdaXrom (which I'd been running on the 860) I got into the initial menu, and was following the instructions on http://www.pdaxrom.org/index.php?showid=42
I got to:
Enter a desired size - like 45 up to 120 depending on your needs. You have to apply "Fix sharp loader NAND 64MB limit ()" on the SL-C760, 860 models to choose more than 64. For SL-C700, 750 models 46 seems to be good.
I read that as "first choose the size, then apply the fix." (Partly that was because the fix is a later menu option, as well as being mentioned second in that instruction.) But after choosing the size as "120," the system told me I'd have to reflash the ROM - okay I'm expecting to do that, but then went into a reboot without giving me the option to apply the fix. I take it I should have applied the fix before changing to size? But the instructions don't specifically say it has to be before.
Anyway, where I am now is that restarting the 3100 just gets me to the initial SHARP screen. I can't get to the service menu at all to continue the process. Please tell me there's some way beyond this now! (I've searched a bit here - I'll be searching more.)
BTW, I did contribute a few days back.
