Member: 235325 Status: Offline Sonork: 100.1593552 Thanks Meter: 523 | Another way to find rx/tx in chinese phones. For example I used one 8800e based on cpu mt6225 were it was unable to find it pinout by classic method(pinfinder or to check voltage and impedance by multimetter) As You can see I traced rx and tx exactly like is in qualcomm cpu’s to find jtag pinout. I hope this will be helpful for someone. Best regards! PS here is the log from my phone after I found it's pinout: Code: COM141 [VCP4] selected module v3.13 Device: Autodetect 6205-6227 NOR Checking data, wait... advanced flash detection enabled Action: read flash ====> Boot ...
