PS3 Unable to connect to SYSCON

[coping0797]

Had a pi with GPIO already laying around so tried my (noob) hand at soldering to read SYSCON from the pi, but I can't seem to connect to SYSCON in my CECHP01, VER-001.

TX and RX are connected to the correct GPIO headers and I've got both cables in my PSU and the PS3 in standby mode. I think the issue is my poor solder job but not sure. I've attached pictures. Thanks.

The soldering could be better, but it looks like its not shorted. Maybe try smaller wires, and trim ends shorter.

I think the issue is you need to do AUTH in capital letters. Maybe several times to get it to work. I see you tried both, but 2nd AUTH may have still failed anyways.

You need both tx and rx, which you have. Make sure tx from ps3 goes to rx, and rx on ps3 goes to tx.

thanks for the post, I realized I had the RX and TX swapped on the ps3 board, but even after swapping them to the right pads, swapping out for smaller wire, and spamming AUTH, I still get the same "response invalid" error.

Could you confirm if these values look normal?

Sorry if stupid question, but did you connect GND of ps3 to the GND of pi yet? I'm not see any other wire except UART.

I see there are pins on this pcb, what if you slide the wire over the pin so it's sheathed then cut along one side of the wire, solder it than cut the other side an do the remaining? or hold the wire upright with the pin & fill the full pad with solder so it wicks updwards.

good question. i did after posting this. i tried soldering to the RF shield, though not sure how well thats working since it really didn't wanna hold. is there a better place on the board to solder to for GND?

probably a good time to mention that I'm not just doing this for fun. this console was packed away for 8y~, with the only problem being the Blu-ray drive not reading discs anymore. took it back out, and it won't display any video from AV or HDMI, and there's 0 sound. no startup music or any menu sounds.it won't boot into safe mode either, just goes from startup > off no matter how long I hold the button for. cleaned the dust and re-pasted CPU/GPU as well.

The USB support legs are ground. Use a multimeter in continuity mode to check.

Sorry, I'm a big noob. could you please send a pic of these support legs?

Bought the USB TTL adapter and after hooking it up, re-soldering, and connecting alligator clips for ground I get the same AUTH error. I've confirmed continuity between the clips with a multimeter, and using the syscontest script shows the TTL adapter as connected.
really not sure what the problem is at this point

okay it randomly decided to work for some reason, so I've got some error codes that appear to point to AV/HDMI unsurprisingly.
@esc0rtd3w @aomsin2526 The chips themselves look fine to me. Are the normal readings for these chips known?
appreciate any help.
