I believe that the installation was at least 4-5 years old.It was funplug-0.7
Unfortunately, I deleted the USB stick where was installed, but I found a copy of ffp root dir in my laptop with sub-dirs inside....this one for sure is older than the one on the USB...is too big to share here.....if help we have to find a way to transfer or put somewhere you can pick it up....

Hi everyone,

this may sound like a weird question, but since my NSA325v2 won't boot anymore (was running just fine until last night), I wanted to run the unbrick procedure.

But I can't figure out how to reboot the device at

piserver@piserver:~ $ kwboot -t -B 115200 /dev/ttyUSB1 -b u-boot.kwb -p
Sending boot message. Please reboot the target.../

Normally I would pull the VCC, but that leads to an error message

bootmsg: Input/output error

I think the UART adapter won't allow removing VCC and just plugging it back in.

Right! don't do that. This NSA325v2 box takes TXD, RXD, and GND. That's all you need.

Which serial converter are you using?
