Sony Xperia XA2 Ultra flashing does not complete? [answered]
I just got a Sony Xperia XA2 Ultra Single-SIM (H3213), it worked fine with Android and I'm now trying to flash Sailfish onto it, as detailed in the instructions. I've gone into developer mode, enabled OEM unlocking and USB debugging. I obtained the OEM unlock key from Sony, and I've unlocked the phone using fastboot. Unfortunately, the actual operation to flash Sailfish onto it from my Linux box fails somewhere halfway. I've now tried this a few times, and it always ends up hanging the same way. Suggestions, anyone?
[Phone started with Volume+/USB into fastboot mode: black screen, blue led on]
