Can SFOS physically damage XA2? [answered]
My second XA2 just broke down in the same way my first one did. The screen wouldn't turn on, then a long press on the power button triggered the red light. It stayed on until I pressed power+volume down. Now the device seems to be dead and doesn't react to any keypress nor is it recognized by a computer with fastboot. Also tried Sony's two minutes method (power+volume up for two minutes). Could this be due to SFOS? There is at least one more person with the same issue, so all in all 3 XA2s failed the same way.
EDIT: I forgot to mention that at least at the stage when the screen wouldn't tturn on in the first place, the device was somehow still working. The yellow light indicating new emails was blinking.
No, I really don't see how that could happen unless you are setting up some special tweaks (which you could as well do in android...) The defaults of SFOS are quite safe.
I'd say it is just coincidence, who knows how many vanilla XA2's are trashed every day?

I have also heard that some device did need that two minutes method and it was quite sensitive to pressing the buttons long enough and not accidentally releasing one during that.
mal ( 2018-12-29 20:22:29 +0300 )editThe device stopped working when it was plugged in and charging, at about 60%. I also added an edit to my original post, as at the stage when the screen wouldn't turn on, the device seemed to be somehow alive.

tortoisedoc ( 2018-12-29 21:52:42 +0300 )editIt is a Single SIM model (don't know which one exactly) and it was branded (not locked) by congstar (German "cheap" brand of T-Mobile)

cpb ( 2018-12-30 00:15:36 +0300 )editAfter the second failure I also thought about this, but I don't have a phone left to try... ;) But as far as I can remember, the first one didn't die during charging.
Daniel.T ( 2018-12-30 07:58:32 +0300 )editThe model of the phone should be printed somewhere (on the box?); I'd suggest for you to contact Jolla Care via zendesk with this info. It seems strange tho, as if SFOS would break XA2, more would have complained.
tortoisedoc ( 2018-12-30 10:59:55 +0300 )editIn the Telegram group there was at least one other person with the same problem.....
BonoNL ( 2018-12-30 13:00:29 +0300 )editNo, SFOS can and will not damage your hardware in any way, but I found this information https://m.youtube.com/watch?v=AJ7nYfN_4eE Which led me to https://talk.sonymobile.com/t5/Xperia-XA2/My-XA2-won-t-turn-back-on/m-p/1356683#M1431 and would explain why there is already a Hardware Revision 3 for Xperia XA2. I was lucky and got a XA2 Rev.3 from o2online during a sale but it's still sealed and I am using a Rev.1 device for playing around at the moment. Anyway, I checked a teardown clip on yt and marked the flex cable area for you. Maybe pressing and holding this area after plugging in the charger would help...
