Serial jailbreaking help

Hey all. I recently decided to try and serial jailbreak my PW3 running a firmware that's too new to software jailbreak, and I've run into a little snag. Following this thread I got to the point where the PuTTY window shows the boot instructions and such, but I can't seem to interrupt the boot process before it boots normally.

I'm assuming PuTTY is supposed to send my inputs from the keyboard as terminal commands to the serial port, but nothing I press seems to do anything.

The connections I'm using are admittedly a little slipshod but I figure if it's showing the terminal on PuTTY it's connected well enough to work, but of course, it doesn't seem to be working 100%, but it makes me think it's something software-related.

I'm not at the computer that I've been using to do it right this moment, but I can furnish screenshots/pictures if requested.

Many thanks!

I had the same problem, but i was using minicom(as against putty) within a terminal window on a linux graphical desktop. No matter what I pressed the autoboot couldn't be halted(even though the terminal displayed all key-presses).

By running minicom on one of the text-only TTY sessions, I was finally able to see the effect of key-presses over the serial connection(i.e. stop autoboot, run commands etc ). Hope this helps someone stuck similarly.

I've had this happen to me with 2 causes:

One time was just a bad ground connection - especially tricky on the 'tropicalised' gooped pw4. I found I can see the serial output with gnd disconnected but it won't talk in the other direction..

But also - I bought a cheap 1v8 TTL adapter from aliexpress and it doesn't seem to send my keystrokes properly, so I've gone back to my ftdi one with a voltage regulator.

Good luck.
