Why you need Global Rom ? For Volte Vowifi ? For that you just need Global Modem Configuration which is very easy. Download SEA firmware and copy Modem Fils to Sogo or SoftBank or whatever your device is. Just copy these file to your firmware and flash it. That's it I will get Global Modem and 4 singles issue will be solve. Plus if you want Volte and Vowifi then there is simple track u have to run one small app and you will get everything. Personally using SOGO2 Xperia 5 ii in UAE and I got everything except 5G network. Trying to solve it also. Soon INSHALLAH.

Brother assalamualaikum ig you didn't get it. Here everyone is trying to flash global rom because of the fact that bootloader is not unlockable in Au/docomo/softbank.

I tried to flash my sony A002SO to SOG02 KDDI. it is looping on start at sony logo. I have tried to flash with stock rom as well but no success.. any solution to this?? newflasher tool have no option for A002SO.

Why are you trying to flash AU variant? To go back to stock, you should be able to use xperifirm and flashtool, or xperifirm and newflasher

Did it work for you? It failed for me i guess Android 12 to Android 11 is an issue

I'm on A13 currently with an unlocked bootloader on this device. Even downgrades shouldn't be an issue. Have you tried the Xperia companion app?

Once you flash A12 you cannot downgrade to 11. Its block by Android. Only if your bootloader is unlocked..

Bootloader is locked because its SimLock devices from Japan and sellers unlock it by code , i don't know how they manage. And there is no single Sim Rom available for 5II in global market. Single sim global firmware is only available for Xperia1 and Mark 2 variant.
