Just wanted to share that the mentioned board works: and finally I got my PW3 jailbreaked.

Some thoughts on it:

use needles and sticky tapes is a very easy and safe way to get a stable RX-TX connection (which I couldn't establish before with soldiering or direct taping wires to the board)
Only attaching RX was and hitting reboot is enough to see serial output on minicom ( so you could go step by step ). Despite all other tutorial; I never unmounted the battery; did never establish a power connection (the board has already a 1.8 V selector); funny fact - the RX/TX connection still worked after I detached the ground (maybe unsafe but seem not to be a strict pre-condition)
the TX line is here to send key-commands, so if you can't interrupt at boot ... this connection is not yet working
'minicom' is a great and super easy tool for serial commandlines under linux/mint/ubuntu and the like (much easier than putty since it is able to handle usb-board and/remove flawlessly - displaying a nice disconnection message when unplugged.
the mentioned serial adapter from aliexpress is cheap and does the job flawlessly: https://www.aliexpress.com/item/4000...629e11c1YE1P96
after having run the basic jailbreak I installed the latest 'jailbreak hotfix' from the snapshots thread .... after that look into the latest factory jailbreak threads to know which version of KUAL you need to install. Puzzled me a little since the older JB tutorial were not aware of issues that will arise with FW >5.9.6
