Hi, thanks for responding. Sorry for the lack of detail. I am using a hi-letgo 3.3v uart and attaching it to a kte-001 motherboard. I'm using mac monterey 12.6.3. Ive referred to the above psx-place tutorial and the github repo tutorial. I've also used a mac tutorial I found posted on this website which is basically just the pyserial and pycryptodome. I have python 2 and 3 installed. I can open the gui, input my uart serial and when I try to authorize I get "auth1 response body invalid. Ive tried switching the rx and tx and also tried re-soldering. I don't know if Im overthinking it but on the github there is a PS3-uart-guide-v2.pdf that mentions sherwood syscons use "ps3_syscon_uart_script23.py" but cant find the file anywhere. Thank so much for your time, I hope this is all the necessary details.
