Xperia XZP cross firmware to convert single SIM G8141 to dual SIM G8142

[Bernardo_Alvarez]

Hi all, I was wonder if it's possible to "convert" a single sim G8141 Xperia XZ premium onto a XZ Premium G8142 (dual sim) by flashing it with a G8142 stock rom, mi cellphone is Telcel from Mexico, and it's annoying to have one device for personal and another one for the job, so I wonder if this "conversion" could be possible (I think that the hardware is the same between single and dual versions, but not sure at all), I've been searching on forums and internet but I only found information regarding convert dual sim onto single sim (vice-versa process as I want to do -and it worked btw-)... so far I already have the correct hybrid sim tray for micro SD/sim card that came with dual version, but I don't want to flash and get a $800 brick, other thing that I realize with other models doing this process (for example Samsung single to dual sim conversion) was about that a second IMEI for sim 2 slot has to be generated to make it work (I didn't understand that so well because I didn't research deeply on this), I don't know if I'll need to do that too with the XZP, but if is necessary I would like to know that too...

Any information or explanation would be appreciated, thanks in advance.

Hello friend,

No single sim phone can be converted to dual sim, the motherboard are direffence in both models.

The dual sim requires a reading system of two sim, a system of dual frequency operation, even if you install a dual rom Mrom for ex.

You will never have the benefits/problems of a dual sim.

Cheers!

OK thank you very much for the response, no option but get a dual sim. ?*

 

[Bernardo_Alvarez]

there's no option to configure an e-sim as sim 2? maybe through an app?

So you're saying you got the tray from a G8142, put both SIMs in, then put it into your G8141 with G8142 firmware flashed and it works?

 

[MaNiAc_4LIFE]

Negative, the tray was there when I purchased the phone, I had a micro SD but then I figured 64gb was enough so I wanted to try the dual SIM, I tried it first, it was not working so I looked to get the fingerprint reader working, found out that it was from a dual SIM model, so I tried it after flashing CE1 and it appears to work perfectly,.. so I'm just waiting for pie

Hi all,
Is it really working ir is it a big joke?
if someone tried thanks for sharing the results.

 

[paijoe88]

I will to try if someone success whit their tutorials

 

[Almar033]

A nano sim can't fit in the sd card tray on my device it is not width enough, I saw pictures on amazon and the 8142 is quite different. So I think it doesn't work.

 

[paijoe88]

This is a different for sim tray for G8141 and G8142
maybe in next week I will try to flash G8142 fw to my G8141 single. At forum else,their someone can successfully.
Stay tune yeah

In 4pda forum I've found at least 2 people who successfully converted their devices to dual sim.
I've ordered combined micro sd and sim tray for g8142.

I will report as soon as I will try this out.

It's possible to make tray wider if you have hands growing from the right place + tools.
Here is the comparison picture for those who can't wait to order new tray.

Upd: I used a paper knife to make my micro sd holder wider to fit a sim.
Installed a g8142 rom and that's it. It's actually working.

So there is no such thing as single sim version

Hi Doom Slayer,

Which ROM do you use. I used the Havoc OS ROM for G8142 on my G8141 and the second SIM-card dosn't work.
thanks.

thanks.

first you need to flash dualsim stock fw with flashtool/newfasher with all wipes, since custom roms rarely contain all the necessary little pieces of software like modem and etc.
