[Estox]

UPDATE: FIXED!!!!!

haha oh my god I sit here literally hours googling, watchign videos reading guides etc. now I reinstalled only python 2 and deleted python 3 now it works xDD sorrrry so if anybody got the same probllems, just delete all python related programms, restart windumb 10, reinstalll only python 2 and it works xD man it is NEVER like: " remove the plug and set it back in" this normaly never works xDD

Hey guys,

long story short. I soldert the UART board to my ps3 board COK-002 looked up some error codes with external mode. works great. Now I soldert the bridge from diag to GND and tryed to set the internal mode. I set the new value from FF to 00, disconnected everything turned it back on and now whants to fix the checksum error, it AUTH just fine I tipe in "eepcsum" hit enter and got a huge error message from python. Im using latest windows 10 build and have python 2.7.18 and 3.10.1 installed (64x)

> AUTH
scopen response invalid
> AUTH
Auth successful
> eepcsum

yeah that was also an issue, but thanks now I got it working ^^ now I can try my hands on my holy CECHB And I hope she got an error that is more or less easy to fix A RSX reball would be not easy for my understandig. Faulty tokins would be okay, I can replace them xD

But it is not this typical YLOD, she turns on runs in XMB or In low demand games like ps1 or ps2 games with no problem when I start a PS3 game it runs for about 5 minutes than YLOD and shut down. when I hit pwoer button it starts right away again. Any sugestions what this could be? sounds like a power loss of nec tokins after a while or a memory error, when the ps3 wants to acces a certain secor of the ram it fails and shuts down ? this would be awefull I can't swap the ram chips out as they are on RSX SOC it selfe or BGA sodlered main ram on the Board >.< I hope I can revive this beauty, these models of ps3 jumped on price so dramatically since the last 2 years thats crazy.
