RE : Dual Sim

Hi,
So I was speaking with Samsung regarding the Dual Sim feature on UK Smartphones, and they said.
"The facility is there but the current UK software does not support this at present."
That would indicate that it's the UK firmware software, does anyone have a link to a firmware or can advise which firmware's support the dual sim capabilities.
My current firmware is : MMB29K.G935FXXU1APF2

I'm not sure you got correct advice from Samsung on this occasion. In order for dual sim to work, it needs hardware support & none of the European models officially sold has it.
As for software/firmware, I think firmware is not different for 935F & 935FD. Both are same.

But the International firmwares come with the "Sim Manager" built in to support dual sims and the UK firmware doesn't come with that.

That depends on whether your hardware supports multiple sim or not. Your firmware will automatically enable "sim manager" based on hardware.
Just to confirm you, my build no is exactly same as yours so underlying firmware is same for both of us, but my hardware has dual sim capability, so I see that "sim manager".
Here's a screenshot of my build attached.

First Balong then bootloop finally brick (Trash,current state)

Hi all,
If you have more idea then me I appreciate the help.
I started from a career locked phone with this fw: ALE-L21C128B130
I unlocked the device officially getting a code from mobile provider.
I made a fastboot flash flash to ALE- L21C432B171.
After this it becames balongc50b311. After it I tried the vendor app to make it to the right version, but the update always failed.
Here I made a mistake, the goal was to make it dual sim, I flashed a wrong fw, L21C432B550 (I think this was), and now it is impossible to use fastboot, neither adb, it's in a bootloop and I tried a lot update app with the 3 button method, all of them failed. Tried the 2 button wipe as well it doesn't help.
I tried transit fws as well, but none of them can pass the bootloop.
I think I need a fw that can work with a this hanged flashed version.
Any idea to get it back?
I should get the picture how the fw-s connected together, which restoration I have to use for what and which transfer and something like this connected to which firmware. Maybe it can get back the phone.
Thank you.

you said your goal is to make dual sim, but you came from dual sim????? B130 is dual sim version, and c128 is Hungarian I think, maybe Telenor. you are actually installed single sim over dual sim and then again dual sim mm, it is no wonder that he is in bootloop. with so many guidelines in the forum Try to return b130 DUAL SIM http://www.carbontesla.com/2015/07/download-huawei-p8-lite-b130-stock-lollipop-firmware-magyar-telecom/#more-3517
do not forget:
even numbers dual sim
odd numbers single sim

Hi, at the beginning I've been on single sim, not dual sim.
Correct, telenor. On the link it is telekom, does it matter or just use a 130 one?

What's your first version?

This was the original one: ALE-L21C128B130

B130 is a Dual Sim version, and prefix c128 means branded to Hungarian Telenor network, Try with link I gave you, and report back. dowonload speed is very slow so maybe U can find on some other server, just be sure it is C432B130

Ok, I try the suggested one:
ALE-L21HUNC150B130

No luck
Can I do anything with the TWRP app or nothing?

Current situation:
When I press power button and up it can go to the menu.
When attach the phone to the computer my computer sees a drive but couldn't open it and couldn't recognized by hisuite or anything.

I'll bring it to the service, it's end
When I get a new one I'll try to make it dualsim again
I'll get the same model, so what should be the steps to make it dualsim?

Ok so you were at telenor branded (c128) but you tried flashing European (c432) version firmwares. Just by unlocking your carrier, will yoube able to do that? I guess you first need to change your region to c432 (unless after unlocking your carrier sets you to c432, afterall Hungary is in Europe). But if it doesn't, then you must change your oeminfo first.
Here's the link to the tutorial

just be sure it is C432B130

Could you explain me why it is so hard to understand. Use C432B130 as explained, and you flashed C150B130 and still think why it doesn't work

Why? Because it's not possible to download from anywhere the C432B130 version fw.

[Question] Unlock Huawei P10 Lite, dual SIM

I boughtta Huawei P10 Lite. It's the WAS LX1 model. It was bought from a vendor who has blocked the use of a single SIM card.
From the specs I've found this model support Dual SIM, has a slot available, but the software does not recognize second SIM.
It is possible to unlock this feature to use the phone in Dual SIM?
I think blocking second SIM was made by the vendor through software.
Best regards,

Hey according to the official huwaei website both WAS-LX1A and WAS-LX1 support dual sim.
It's possible to enable the second sim but I don't know how, maybe custom roms

The phone is most likely carrier locked, there is no reason to issue special software to block the use of a second SIM card for a phone sold for dual SIM use (and sounds like something you could sue the company for).
Are you trying to insert SIM cards from 2 different carriers? Ask your carrier if your phone is carrier locked and if they are willing to unlock it and report back.

hi,
i am working on it, firstly i rooted the phone with twrp and this is working, but still i dont see the settings for dual sim.

try this go to /hw_oem/prop/local.prop
look for ro.dual.sim.phone=false change it to true and reboot

It won't work, you will have to find a OEMInfo TWRP partition from a dual sim P1 0 lite, or use this alternative : https://forum.xda-developers.com/showpost.php?p=72523572&postcount=4

i got some backup from TWRP back (restore) and the phone swich on to EMUI with some funcktional and app bugs.
so it is working but something is still messed up.
could somebody give me full TWRP backup with system and so on that i can restore whole phone? will it work like this?
other option is to dowload firmware but the instalation stops on 5% and as always fail.
so if this could be an option plese can somebody make fresh pure copy of all partitions from WAS Lx1A and upload it.
i tryied one from forum but this is not working for me.

I read this post some days ago, when i bought the same device with the same kind of sim "lock".
I contacted the huawei support, asking if it was possible to have the complete firmware because it is not fair buying it expecting it to be dual sim.. and it is not.
Their answer, where in a previous mail they told me that p10 lite german version is not dual sim:
Dear Customer,
thank you for your reply.
Sadly your device is a single-SIM device.
All the devices have the same second hybrid slot for 1 memory-card and 1 SIM-card anyway. But the needed hardware parts are missing. So it is not possible to get this DUAL-SIM feature with an other firmware.
Hopefully this inforamtions are what you've been searching for.
For further questions please do not hesitate to contact us again.

Some dual sim phones are not mean't to sold in some countries, if you need a dual sim phone, make sure it has been stated before you buy it, buying a single sim phone and expecting it suport dual sim is not the right way to go. Countries like korea and Japan, although there are more countries, they never sell dual sim phones, as these countries only sells phones through carriers, so phones are normally locked, and does not support dual carrier network.
China has the biggest market for dual sim phones, and Hong Kong has only started selling dual sim phones in the past few years, as many people from Hong Kong are buy dual sim phones from china, probably don't want to lose out on business, so most mid to high end phones and many low end phones now support dual sim.

On their website, t-mobile, there was nothing about it being single or dual sim. I found the specs both at Huawei website and gsmarena.
This last one, writes:
SIM Single SIM (Nano-SIM) or Dual SIM (Nano-SIM, dual stand-by)
But the Huawei website's got plenty of p10 lite, each with both single and dual sim for each product code.
Mine is a WAX-LX1 and is both single and dual.
I did read nothing on t-mobile website, about it working on single or dual sim, you know.. like those T&C where you'd read it ..
I supposed it was dual. Because it is nice to have more than less.
It is not. It is single.
But the funny thing is that I'm not really interested at this, because I own a Zenfone too and this is dual sim (now using as an iPod, android version eheheh).
Still.. If someone managed to "hack" it with another firmware, that would be great!
But, Huawei wrote there are hardware part missing.
I don't really believe it.. And I'm not even skilled to try and flash firmware.
If someone, someday, manages to have the second sim working, I'd love to follow the process and having it unlocked as well. Else, nevermind..

Is this T mobile in the US, I think the US is not know to have many dual sim phones, especial from the main brands like Samsung, Sony, LG and Hauwei, and if they are not stated dual sim, it's usually a single sim version, or refer to the model number.
I think reading somewhere, someone has done it with the P10, but haven't heard about the P10 Lite.

Germany, or better, Austria. Since there isn't a website for Huawei Austria, and the customer support is the one for Germany.
...At least it is not sim-lock! But I still believe it is firmware-related. I don't think they intentionally removed hardware. It would cost more to produce lots of the same phones with different hardware than flashing them with different firmware.
We're here, simply waiting for the guy with a unlocked P10 Lite dual sim working, who can share its backup..

If the concept is similar as for P9 lite, you guys just need to read oeminfo using Twrp from some dual.sim verzion of device, then make flashable zip file and flesh it throu Twrp. After fleshing the firmware is corupted and just need full stock firmware recovery with compatible version of vendor using dload method. But converting single sim into dual sim in Nougat is more difucult then on MM. On P9 lite we only success to convert it using MM. After upgrading on N its dificilts but not imposible. Just find oeminfo share it and make a try. After unlocking dual sim option the phone still has one Imei but two open sim slots, and its normal. All the best!

No VoLTE on X Compact

Hi,
I am from Germany and I bought a phone from UK with O2 pay monthly software version. I hoped for a VoLTE option with Oreo update, but while Oreo is here, VoLTE option is not. Do I have to reflash to german software or is there another way? And in case of reflashing, can a backup made with sony compagnion be restored after software change? I would use german software version with the same build number (34.4.A.0.364) as my O2 UK of course.

Vodafone Germany is saying VoLTE with Vodafone branded phones only. Mine is unbranded and Wifi Call works, as Vodafone says, but not VoLTE as Vodafone says again

Well, I am willing to switch to german O2 branding if mandatory für VoLTE using provider blau.de, but I think it isn't.
Do you have a switch for VoLTE but it just doesn't work or don't you have a switch at all?
https://support.sonymobile.com/de/xperiaxcompact/kb/801930746ffcf563015c0bfaac370057e6/
Can anybody answer my other questions?

I've never used it, but I've seen a 'vo enabler' module in Magisk downloads...

For me, with German provider o2, the "Customized DE" branding (1305-6830) provides me with VoLTE and VoWiFi. My phone originally came with the "Customized FR" branding (1305-4777) and I had to flash the German branding onto it to get these additional functionalities. I would recommend to make a backup before flashing the German branding, but for me it was NOT necessary to wipe anything.

Just to be sure. You didn't wipe anything and did not loose any data? So after flashing the phone was like before (apps, data, settings), just with a VoLTE switch?

Yes. I first used Xperifirm to get the firmware with the "Customized DE" branding. I was lucky enough to get exactly the same firmware version that was already installed, just with the right branding now. Then I used FlashTool to create the FTF and flash it to the device. I did not check any of the "wipe" switches. When FlashTool was done, I restarted the phone. After maybe 30 seconds, I got a message saying that now the phone is getting optimized for my operator and will reboot (I cannot remember the exact wording). After this reboot, the switches for VoLTE and VoWiFi were there. I had no data loss at all, but I still did a backup before and would advise anybody to do so just to be on the safe side.

OK, I will go for it on sunday. "Customized DE" firmware is downloaded (the new one with patch level 1. february) and my phone has updated to the same one today, just with O2 UK branding.

Does anybody know what has to be allowed through the firewall (afwall) for volte or vowifi to work? i have the firmware but get no connection

Oneplus 8 Pro Dual SIM

Since the EU version of the OnePlus seems to work with Dual SIM.
Can we flash the US version with the EU OxygenOS and be able to get Dual SIM working in the US?

Actually, this is what I did. Using US Version (Model: IN2025) and then was flashing with the EU Oxygen OS Version 10.5.4. After the flash, the update to Oxygen OS 10.5.6.IN11BA automatically was retrieved and installed.
Two things are surprising to me:
- I was expecting that after 10.5.6 upgrade, dual SIM should work, when limiting the network to 2G/3G/4G. However it still shows that the dual-sim function is not working.
- I thought that flashing the US device with EU, would also change the model from IN2025.
What am I missing here?
Thanks & Best.

OnePlus chat support told me that only configuration and software is different between the regional devices, hardware is all the same.
However it also didn't solve what I wanted to achieve - dual-SIM and (at best) also European bands - like n78 ... :crying:
