I'm doing a 256MB jasper. I got the nand to dump. I havn't installed XBR as I can't get the JTAG wiring installed properly. I solder in the JTAG wiring, but the system still boots in stock dash/nand fine. My questions are, is there a way to individually test each wire from the jtag wiring to make sure its working, also is it a specific wire that stops the console from booting or is it all of the JTAG wires together, and is there anyway a console with the JTAG wiring installed 'properly' would boot normally even with stock dash/nand?
I'm asuming I eff'd up the DB1F1(lifted pad) notch or what ever, but I thought that if I messed that up, my system shouldn't even boot normally? I tried FT1U2, and it seems to have gotten in(looks good, with pad intact), but im still able to boot, I would like to make sure I get the JTAG wiring installed 'properly' before I attmpt to write XBR.
Another big question I have is, after lifting the pad at DB1F1, is it at all possible to still use it(like using flux paste). I can stil solder to it. I just have no way of even telling if thats my problem or if its another wire.
Any help is greatly appreciated. Thanks in advance.

I would test out XBR... just make sure you have 2-3 good matching dumps of your original NAND before writing anything. That way if the JTAG/XBR doesn't work, you can always put back your original.
I had lots of problems when writing over LPT cable. I found the fastest and easiest way is to just flash XELL first and use Gentoo Live cd beta2 to boot linux, then use lflash to flash XBR... works much better since it avoids write errors and automatically reallocates bad blocks, plus it takes only a few minutes instead of hours over LPT.
