Hi, I forwarded it on sony service center! Can you assure is it only a software problem and fixable? I try the last night the Repair in Sony Companion but didn't work. I didn't know what that small yellow in sim card. I cant boot it up into home menu because it stuck on SONY power logo.

I can't assure anything as long as I don't have my hands on the phone. And how come you sent it to Sony's service center and they couldn't fix it for you?

If you failed your software update then it is most probably fixable by performing a software repair using Xperia Companion. Keep your cool and retry the process while your phone is charged and turned off.

I tried already the repair but it failed. I think It cant install the Nougat Version in my XA Ultra. Thats why i send it in the service centre it will takes 3 days to be checked tho because it will be shipped. Ill try to remain calm.

I upgrade it using Xperia Companion because OTA update always failed.

Also, if you check  Gaeoul repairing his XA Ultra from 8PM to 5AM still didnt repaired i think. Thats why im here freaking out hahahaha
