Unsolved XENON JTAG RROD after flashing

[mondychan77]

yo guys, had fully working retail (no mods ever done to the console) XENON xbox360
today I have sucesfully read NAND of my xbox two times, compared, all fine
created XELL-reloaded and wrote it sucesfully
did the two diodes lines between J2D2 and J1F1 plus the inter link on J2D2, i believe my soldering is all good and diode orientation is fine too

even tho i get rrod, tried flashing retail .bin back to the console too, to no avail (i have not yet tested to desolder everything out), the secondary error code seems to be 0022
no video output

any advice I could test/try? thanks in advance

Xenons the least reliable motherboards found in 360s, and are ~12 years old.

0022 can be CPU, GPU, NAND, software error

depends on how much time it get RROD

2-7s = Front side bus problem, cpu can't read bootloader loaded in memory (either CPU or GPU northbridge)
15-20s nand image missmatch with fuseset 02 or LDV, Broken Nand or southbridge flash controller.
30s-1minute, CPU stuck at slow speed due to PLL broken (mostly happens on poor soldering at pll points)
over 1 minute, GPU broken

0022 is a generic code with multiple problems that can cause is.
Ranging from a bad flash to hardware failure.
Do you have pics of your soldering?

true, but it has been running great till i fiddled with it, so i quess something on my side has been done wrong, but its also possible that while dissasembling it, i could break something

right after turning on, 4 lets flashing

so to the dumpster i quess?
