I've modded about 20 1.6-1.6b's with sst49lf020 (not sst49lf020a). I program them myself, jump all the wires on the chip, rebuild the lpc and wire the chip to the lpc. I've had no problems until a couple days ago.
I flashed one with m8_16plus for a 1.6b box, and all worked great. After transfering some files and trying to jump back to avalaunch dash, it locked at a blank screen, and the eject lcd started to flash (just like it would had I wired the chip wrong). I assumed I had a bad solder point, so I resoldered all points and tried again.
It booted fine, but after a while it locked (it only locks up when going from one app to another, never during execution of an application or game.). I rechecked this thing at least 10 times and I'm sure it's correct. Another strange thing is that after locking up, it wont boot at all. If I leave it sit unplugged it will boot after a while (hours).
Now it gets better.....
I let that one be, and started to mod a 1.6 with m8_16 and the exact same thing as above happened. Now I'm really pulling my hair out since I've never had a problem modding a 1.6, and now I have 2 in a row doing the same thing....... The only thing different is I did change to a new spool of wire before modding these, and it seems a tad thinner. The wire I used for these mods is 30 AWG Kynar. I'm not sure the gauge of the wire I've been using for the last 3 years, but it is a bit stiffer (not much, but noticable).
So, here I sit not having a clue what the prob may be, so any help or ideas would be greatly appreciated.
Thanks
