Recovery vs. warranty
My second Jolla I bought in December and just started using a week ago, after crashes on my old one became intolerable, seems to have bitten the dust. I think it might be a hardware problem as it started with the display suddenly turning off (as in a traditional crash due to high CPU load/bad battery), then coming back on after a while but everything being extremely slow despite low CPU load. A few minutes later the screen went black again and since then, the Jolla hasn't been able to boot. I don't even get a Jolla logo, just a white LED that turns off after a few seconds. I suspect it might be a display problem, on one in maybe a dozen boot attempts I suddenly got the normal PIN prompt but as soon as I typed a number the screen went black again. The on/off button seems to do nothing at all, volume down sometimes causes the Jolla to vibrate. The only thing that works as designed is fastboot, I can get to the recovery menu and shell via telnet. On the other hand, it might be a software issue as well since problems started just after I installed Dalvik and the store/web sockets version of Signal, everything was fine as long as I didn't have that evil Android stuff on the Jolla ;).
Now I'm wondering if I should try to use recovery or not, as I (surprisingly) like SFOS 2.0 and don't want to end up stuck on 1.0.7 or something. Maybe I should just send it to Care on warranty - did anyone successfully get their Jolla repaired/replaced on warranty after December?
