Hello,
Just get a used Xperia X today around 200$ in my country (VN). After upgrade-loop, it now on 7.1.1. I dig around internet for offical 6.0.1 ROM but couldnot find version for my country (1302-3377 VN). So please help me clear:
1. Can I use ROM version from other country like HK or TW for my VN phone
2. Do I really need backup DRM keys, what happend if dont have these keys? I see someone post that it need when I resell this phone, but I dont have plan to resell any phone of mine (I still keep 1 N900, 4 N9s in my collection)
Thank you.
