my firmware version: 5.8.2 (PW3)
I managed to jailbreak it as described in

It seems i did it right as I've installed: KUAL, Mr Package Installed and UsbNetwork all from
https://www.mobileread.com/forums/sho...d.php?t=225030
and they are working just fine.
I've tried to use gtranslator extension as described in
https://www.mobileread.com/forums/sho...d.php?t=235859
but it didn't work.
Maybe i should leave it at version 5.7.4 ?
