Hey guys, so i lifted DB1F1 and FT1U2 and now i am onto the boxxdr transistor method using an ALT. point on the southbridge. However, I have successfully obtained my CPU key and have a good nand dump, yet - upon flashing freeboot - I get an E79 error message, and sometimes the xbox won't even boot at all. I've heard that FT1U2 is a test point

Looking back, the whole trace coming from FT1U2 was ripped off the pcb completely (well most of it on that side of the board), in a pitiful attempt to solder to the trace, I done a hatchet job :( ... Ive uploaded a pic!

Can I retrace, if so, could you guys please tell me how? I think i may with kynar, just don't know where to go :(

Anyway, any idea what I can do with my xbox. Please note i have fully working nand backup + cpu key, even if the board is fuzzed is there anything i can do with it... AT ALL?

Also folks, ive uploaded a diagrammatic version to help you see. Perhaps a fix is possible, no?

EDIT: I also understand that a lot of you wouldn't want to tap this thread with a 40 foot pole, however, please help as i'm EL Desperado ATM. :(

Also, Im using JTAG tool and i am upgrading nand from stock 7371 with my CPU KEY to a freeBOOT 13604 xellous eject and the smc is set to AUD_CLAMP only. I read somewhere that the SMC config in the nand has to be different for the boxxdr transistor method. Any idea where i could get this?

i'm not sure mate i've never destroyed it like that to know whether it affects the booting of the console. i don't think it would matter though unless your soldering is bridgeing it also. e79 on a jtag is usually bad wiring or wrong smc config. your jtag wiring looks fine to me so i'm thinking config myself. obviously repairing the trace would be a good idea though and your diagram way should repair it on the underside. i know the db1f1 point on the top can be ripped out and not affect the console.

Well thanks very much, the ENTIRE GROUP of FT1U2 pads are completely f**ked as well as the trace coming from it :(
I was told it was a test point, but f**k it im going to get some kynar and join everything up to each other and pray xD

BESIDES, I have a good working Keyvault + nand dump and if the board is f**ked how much do you think i could sell it for?

not much mate. that would need the cpu transplanting to another working board if the repair fails to make any use of it. you could then write the nand to the donor board and be all set.

i'd definatly wire it with the alt wiring open tray aud clamp method first and rewrite the freeboot with this smc incase it is the config wrong. the soldering for that smc is piss easy.

*sigh* tried everything. Sadly it was 7371 falcon and now i think its dead. Get E79 upon boot. Yet still have CPU key and fully working nand from previous xell write. Surely there must be some JTAG god who can help me/there must be something i can do. I dont want to waste money on another xbox, sell it perhaps, maybe even KV?

If you can get it to boot with your original nand, then why not buy a Coolrunner? They are cheap and works really well on a Falcon ;)
