I could not update my OS for some time (I believe due ‘stop version’ and some packages not allowing it).
After couple of months I decided to try and did follow this page:
unfortunately when I keep “volume up” and connect to cable, led goes blue for some time but when I run script (flash.sh) I get that:
Flash utility v1.2
Searching device to flash…
even fastboot is showing device for short time only, anything to try to reinstal system?
