As the title says, can you flash the single sim version of S8/S8+ with dual sims version?
Are there any differences in hardware?
The firmware the duos model uses is the same as the single SIM model. The firmware detects the extra hardware can installs SIM manager.

You can't enable dual SIM on a single SIM model because it's missing hardware for the second sim

The 2nd imei is missing.
Hello.
Its not possible do to this, because today i try to make this and the firmware detects only the micro SD and one SIM card.
But the dual version SIM i think its possible do detect 2 card sim and micro SD.
Sorry for my english...i am portuguese and some times i dont remember some words.
Yes Its work make Single convert to Dual Sim.
BUT you cant use Sim 2 , they have no Number (000000000000000/07) its invalid.
only FD version have Sim 1&2 IMEI
So its possible to flash the duos firmware, but because there's no second IMEI it wouldn't work?
And if you purchased a hybrid dual sim tray, (which are readily availible) you would still have the 0000000........... for the second sim Correct?? And if you had a spare IMEI for the second sim, then how would you make the second IMEI work? Is there a IMEI flasher program for samsung phones??
I know there's one for MTK devices, so where's the sammy software program??
Surely this must be able to be done. If the mate 10 pro can be converted, the why not the s8 or even the s9/s9+??
Following.
Ok so what I understand and could be wrong. Is the hardware is there to read either if you look at the hybrid trays they are setup to read either 2 sims and no sd card or 1 SIM 1 sd.
So bassicly it comes down. To if that is true. For all models.
I have seen settings with 0000 imei for SIM card 2. But the option is there so what ever needs to be done in that case can be done. But of coarse I'm not getting Into imei options on s8. But they are possible. So it could be possible.
So bassicly some one needs to order the hybrid sim tray. Get the aluminum ones. But then try so see in hidden menues in settings and such see if detection of second sim is even possible.
So to test the one who does it at worst out a couple bucks for a tray. Of coarse check hidden menus.
First before flashing firmwares. Th3n after all that. Easily slide the tray in just for caution. No jamming as not to possibly damage anything.
IMEI Guru LLC Service tool can write a second IMEI directly to the system.

Hey Guys,
I bought the Moto X Force in India. According to "About Phone", it says it's the EU version.
It has the slot of SIM2 and it even has the contacts. I put a fresh SIM into the SIM2 slot and it came out all scratched up. So, I'm sure it even has the contacts.
By putting these settings in build.prop
ro.gsm.data_retry_config=default_randomization=2000,max_retries=infinite,1000,1000,80000,125000,485000,905000
persist.radio.plmn_name_cmp=1
persist.radio.force_get_pref=1
persist.radio.multisim.config=dsds
It enabled the Dual SIM mode in android but it couldn't detect it. Still says no SIM. My guess is, it might have to do with the modem.
I was thinking if someone can post the modem dump from the Mexican or Brazilian version and if I can flash it, maybe it can work.
Of course, it might be a stupid idea. Let me know what you guys think. Is this worth trying?
Regards,
Suhas
If it has a second SIM slot, it will need a second imei number

For older models like X play. You can still use it for data. http://forum.xda-developers.com/showpost.php?p=68994968&postcount=57
Currently, the IMEI 2 is 0.
@suhas93 Did it work finally ? I was thinking of flashing modem from mexican version or XT1581.
Hello,
I want to unlock the 2nd Sim slot in my P8 Lite (ALE-L21) as it has been disabled for the UK market. Huawei have told me it is not possible as the hardware is not present for the 2nd sim which contradicts what I have seen on here which is a bit strange, maybe it’s a warranty thing?
Anyhow Is there a simple step by step process to get the 2nd sim slot activated?
Current Build number: Ale-L21C432B595

activate second sim

This is just a firmware converting ant it won't enable the second Sim slot because you will still have only IMEI 1
You need IMEI 2 to use the second slot and I'm not sure but probably it's possible to add it using some tools like Z3X Box
BTW this process is illegal in many countries so I don't recommend it.

yes it will enable the second sim,just try and you will see(p8 lite came from manufacturer in dual sim,but some brands like vodafone for example they putt a brand firmware with a single sim)

Already tried that. You will have the dual sim management in settings but since you only have one IMEI you will still can't use the second Sim
All experts,
I would like to 'enable' on my S7 edge the dual SIM function. The 'international' card holder could care 2 Nano SIM card, but the G935F is supporting just one SIM.
It's possible to do this without root? It's possible to install the G935FD firmware or are there radio baseband modifications nesessary?
In addition, I need to run the Blackberry Works app (former Good). This app is not running on a rooted phone.
Thanks for any comment and help.

You can't.
Single sim variant have only 1 imei number but dual sim variant have 2 which are for each sim. You can't just add more imei to your phone and even if you can, it is illegal.
Also card holder of single sim variant cannot hold 2 sim cards, only 1 sim card+microsd.
G935fd and G935f firmwares also are identical. So you can flash it on your phone but it's not going to enable dual sim on single sim variant.

While don't you save yourself the strength and buy the dual sim version, because like the other guy above said, its impossible to use dual sim on a single sim. Backup your data, get the dual sim version and restore back.
Thanks for the first feedback.
- single SIM and dual SIM card holders are available at eBay etc. The HW of the two phone is 100% identical. A friend of mine converted his G935f to G935fd with the support of a Vietnamese service guy over TeamViewer. My problem is the root after this.
BTW: Buying a DUOS is not a problem, it cost just some money
Thanks for expert tips...

It IS possible to convert G930/5F to G930/5FD. Only you have to do is clone your IMEI as IMEI 2 using Z3x or other software and replace SIM + microSD tray to SIM + SIM/microSD or DIY
That's in theory, but I personally need assist in:
1. Downgrading to Nougat, because Z3x doesn't support (yet) the newest /efs to modify cert to add that IMEI 2 or at least I can't find new enough which supports Oreo
1.1 Need to factory reset!
2. Getting root
3. Adding IMEI 2
3.1. Need to factory reset!
4. Updating back to official Oreo without root, if possible. I'm perfectly fine with normal functions, don't need the root for anything. Only I need is second SIM. I believe that I need to flash official Nougat first over rooted Nougat and update it using FOTA to Oreo? If not, flashing Oreo by Odin.
I will very appreciate any help with confirming these steps (is it correct way?) and helping me to get needed files and stuff to do it.
All experts,
I have replace the motherboard of my Samsung Galaxy S7 Edge, dual sim variant (SM-G935FD) with that of single sim variant but a frequent prompt of sim card mode shift is happened, saying "the sim card mode is witched from dual sim to single sim mode, which requires a rest to factory setting and restart". Since there is only a restart option, I'm forced to hit it and restart frequently but not working yet. How can I fix this problem?
Thanks for any comment and help!
Yoseph
I also used z3x and it works flawlessly im on Oreo s7 edge exynos.

What is your internal memory size? Because if you have 64GB it's dual sim model and you have flashed wrong firmware. Single sim has only 32GB.
Do you see dual sim options in phone settings (dual sim calls, etc..)?
Is device rooted?
I have the Dual Sim settings, but my internal memory is 32gb.
How can I flash the correct rom on it? LG Bridge does not do it.
Are you sure? Have you tried mobile with 2 sim cards inserted?
Because on single sim model you can also insert sim in second slot, but this slot only work with microsd cards.
hello, i have a j7 single sim for work. I need dual sim, can i use two sims? changing rom? is it posible in some way?

I believe J730F is actually a dual sim model. Moreover the fact that two slots are already present on your phone confirms its dual sim capability.
Dial*#1234#. Now check your model no . I think your handset has dual sim support.
