Sony Xperia 1ii XQ-AT51 to XQAT52 Conversion possible?

[Lokeshvenkatashiah]

Hi,
Im owning a Sony Xperia 1ii XQ-AT51 US customized and currently using it India. My phone has no VOLTE provisioned enabled( Using Airtel Carrier) . I tried all UK, RU Customization I could not enable VOLTE. Can i flash AT52 Firmware on AT51 to enable VOLTE ? Will there be a problem?

Thanks
Lokesh

It should work, but AFAIK you need to be on your region's firmware to get VoLTE. If you have a sim-enabled VoLTE like Google Fi, it'll work. Unsure if there is a customized India firmware though.

But yeah, flashing AT52 on AT51 will work fine.

EDIT: Read on another topic that someone flashed Customized SEA and was able to get VoLTE + 5G working in India. You can try that!

LTE or VOLTE?

 

[Lokeshvenkatashiah]

LTE or VOLTE?

WIFI Calling working, VOLTE also working. Just testing using JIO SIM. But no logo in the network indicator. In mobile and network setting i found use VOLTE when available.

Never used Jio app for making calls. VOLTE WOKS FINE when you flash the XQ-AT52 SEA firmware. But going back to US Customized needs updated firmware 288

I'm having trouble converting from HK AT52 to US AT51. I've done it about 10 times and every time it is corrupt.

Does it make any difference that I have the green model with 12gb RAM?

Are there any special steps for getting 58.1.A.5.441 (US firmware) to work on my phone?
