I updated my first Jolla which I got from Narinkkatori. Update failed until I finally removed browser history and some other stuff. Update installation took long time and when it booted, it did not request for locking code nor pin code. Double tap and swype to bring up lock screen. I can open the device with locking code, but none of the simple methods will make this to ask sim cards pin-code, hence no 2G/3G/4G connections. Also WLAN does not work either. So this Jolla is completely without normal networking. I will not update my other J1's before I get this resolved. Will report back.
