I built that damn thing twice! I know they are both wired correctly. I've gone over them about 20 times each, and compared them with other layouts people used with that same schematic. However, it always fails to write x0000000 (first address). It writes 98% of the main.hex then fails every time. According to winpic the hardware is "OK" and the device is "unknown". I see someone used a 100ohm instead of a 220, could that help?

Got another schematic? That one hates me.

Short question: If one puts the flasher into bootloader mode, then, when plugged into the computer it sees it and installs the drivers, does this mean picxboot.hex flashed 100% correctly?

Alright, I did flash the picxboot.hex with my "pic+pro". However to get it to read the picxboot I had to open it "QL_PROGen.exe" and save it,  then it would open in "QL2005EN". Now, I'm not too sure if the parsing between the 2 programs created errors, but when I put my flasher into bootloader it did pop up and let me use "PDFSUSB.exe" to flash the chip. Which I did, and it said successful. My flasher still isn't being seen by nandpro though, so it's either something to do with the wiring with the flasher and/or xbox mobo, or the picxboot.hex became somehow corrupt.

Also, I'm not too sure which one I should be using, but I'm using the .hex from "PICFLASH_v3b_plus2".
