Bring in the pro's JTAG
EDIT! soldered everything even better im able to write the orig.bin and it comes back identical. going to update this once i get a good write of xbr or xell.
i flashed the orig nand back to the xbox. 360 boots up just fine. it seems anyone having this problem with e79 have something wrong with the jtag connections. im so sure i got a good connection =/ im using the diodes on the pins 3 and 4 and over where the jumper wire goes. well personally i think thats the best jumper wire ive ever done! it looks so nice and neat. im guessing my problem should be simple to fix. is there any other pin connections i can use for the jtag? an alternate pin out schematic would rock! im sure there's one out there so if you can find it let me know.
also im going to try the 3 330 ohm resistors after i flash one more time with xbr.
My only problem is getting a good write and to boot the xbox
I can build the file for xbr but i cant open it in degrade once im done. idk if anyone can. however i only get error 79 and a single red light flashing. i get 3 red rings once i power on with ejecting dvd drive.
Ive gone through different tests and trial and errors. this is the fastest it goes to error 79 with just the kv in the xbr instead of both kv and config.
this all may have something to do with me flashing it while the dvd and rf board (ring of lights) was unplugged. but i wanted to see if it would still work.
xell will not work at all.
My only explanation is im not getting a good write to the nand. ive had my bios on the pc at EPP and at 278mh or something like that last part ill check again and update because im going to up the mh by 100.
it may give a stronger write. it may make things mess up worse. who knows trial and error. once im done i will write a xenon trial and error tut.
I can say is once i wrote the image to the nand xbr and with kv and config injected at the same time once i dumped the box after i checked it in comparison with total commander there are 6 differences. and every time i dump it and compare. there is always 6 differences. whether it be a bad write file that i dumped in comparison with a good xbr kv+config its the same 6 differences. but they are completely different at the same time. some reason im getting 6 errors while writing at the same place however it only writes just a bit each time i assume.
This is just a note here but, after unplugging the power and leaving it off for a few seconds.
(till the amber light on the power brick goes out) and plug it back in i sometimes get no screen or longer waiting times before a single red flashing light and error 79. sometimes 3 red lights. but it depends on what i just wrote to the nand.)
This would be much easier on finding the problem and solving if it didn't take 45 mins each dump and write. the write may take longer im not really timing anymore they both feel like forever.
As for solder points. everything is perfect except for one thing. because i forced myself to check weather the diodes on the jtag hack pin-out were backwards
(they weren't and they were soldered perfect) i accidentally pulled one off.
This wasn't easy as i was trying to remove some heat shrink tubing off the diode because i couldn't see its black line accommodating the accidental yank lol, was me pulling out the copper ring on the surface. there's not much for me to solder to now.. but i have it connected *the diode is basically in the hole now soldered down*
Now it just seems to boot faster into error 79 making me think its not my writing anymore because i chose to write with the xbr file and only the kv injected.
im going to do one more read/dump of the nand to check if the xbr+kv i created on the pc is identical to the one i flashed to the nand.
UPDATE* i re soldered everything! i put each wire in the hole of the connection. soldered them on top and bottom of the MoBo i booted up and it still gave 1 red light error 79
so it wasn't my jtag. its completely the write. it may be the computer im using. but i don't understand why because i could get 10 reads/dumps in a row and they would all be identical. im going to do that read one more time compare then if it is bad again im going to write back the orig.bin and see if it boots. if not. then i know its my pc not able to write correctly.
i have a question though.
if i didn't have the original dump. would it be possible to get the cpu key if i could get xell to load and create a new image. i saw some people talking about it. anyone able tohelp because ive read in many forums of this same problem. mostly with falcon boards a few have my same problem. we all may have something in common however and if i can figure what that is then there is a solution possibly.
my specs for others to read and hopefully get something out of it.

it will not flash ny xbox360 dvd drives. Ive only tried Hitachi and Toshiba on it.
both freeze and lock up.
degraded 1.1 shows no bad blocks in nand dumps.
commander compared several dumps and they were all identical in different orders 1 and 2 - 2 and 3 - 3 and 1
Cable is roughly 18 inches in length 5 100 ohm resistors 1/2 watt
if anyone knows if its possible for a write error to occurs when the cable is at this length and 100 ohm 1/2 watt resistors are in place, speak up! maybe removing them would help? or adding 1/4 watt 100 ohm resistors could help.
i flashed the nand with kv and config patched xbr while the r6t3 resistor was off and read/dumped the orig.bin while it was on.
I would like to know if that could cause the dumps and writes to be different. because i don't remember if i dumped the nand once more after removal of the resistor efuse.
tell me some common problems and symptoms of your 360 not working after a flash.
what pc even.
pictures below show a screenshot of the 360 the wiring,
