Sony Xperia M4 Aqua Dual E2363 can not update to latest firmware

[Antonis86]

I have a M4 Aqua Dual E2363 that was a prize from Xperia Lounge contest.


My problem is, the phone is in the first firmware 26.1.B.1.85 and can not detect the newer firmware 26.1.B.2.147


I check in PC Companion and it said that i have the newest firmware.


What can i do to update my phone???


PS. Can i flash stock Sony firmware with 26.1.B.2.147 ??

If you got the phone from Sony you have Sony's firmware, as to why you can't update the phone, its quite simple, you have to wait for the update to be approved and released in your country/region. 

On a side note, congrats on winning a M4

Its simple the firmware installed in your phone is not the customized one and mostly a firmware built for demo purpose so they wont get any updates. Yes you can flash stock E2363 region specific firmware using flashtool.

Thanks both for your responses!!!

I think that @balakrishnaga has a point. I just saw in the phone box that it said ''DEMO ONLY NOT FOR SALE''

Now i think i must flash it my self the latest firmware...
