Flashing firmware on tab s7+ - Samsung Galaxy Tab S7 / S7 Plus Questions & Answer

To keep it short and sweet, I realised when you take the SD card slot, under the plastic cover there is a sim card slot. Theoretically, if I was to flash the tab s7+ 5G firmware and put the sim card in would it work?

Probably not. For two reasons:
a) The WiFi only version won't have the 5G antennas needed.
b) The 5G radios would have to be turned on at the chip level; meaning Qualcomm would have to do it. The radios are enabled/disabled at the factory (meaning Qualcomm), not by the device OEM.

[Q] Possible clone S3 purchased; what to do ?

Hey all,
Through a combination of misfortune and greed, I ended with a possible clone Galaxy S3 last night. I think it could be a clone, as the About Phone options are not complete (No Hardware/CPU info) and lack of Samsung Apps.
Also, the internal memory is less than 1GB.
Externally, the phone looks real, including the identification sticker at the back. Internally, there are some issues.
The phone is only connecting to 2G networks on Edge or Gprs, even though the SIM will connect to 3G or HSPA on another handset (means the SIM is correctly working on 3G).
In addition, there boot logo also splashes Android logo between Samsung, unlike normal S3.
Unlike my work mate's S3, which I compared it against, the SIM card and MicroSD card slots are located towards the top of the battery. Whereas my colleague's SIM card and MicroSD card slots are located towards the bottom. My phone takes a normal SIM, whereas my colleague's phone takes a Micro SIM.
I believe I have ended up with a clone. What is the best I could do with it (technical suggestions) ? I did not buy it to use, as I have another working handset with me.

You won't get any support here as you don't have the genuine S3. What you can do is sell that one to buy a genuine S3 or find a forum that supports that clone.
Here you won't get any so tough luck for you. You should've been more careful on buying such devices.
Can you kindly confirm if this is indeed a clone, as I am unsure myself.

Sorry it does not respond to the code, meaning it is a clone.
yeah.. if it was on stock rom.. check the android version if 4.1.9 and if it is, it was a clone
The android version is 4.0.3

The 'minor' hardware differences are the clincher, it's very difficult to exactly replicate both form and function when reverse engineering. Some clones can look very similar from the outside but take the back off and it becomes clear that they are working from a limited bin of parts to get something that will even switch on.

lel2asaf your phone is a clone :/ Try checking the paper under the phone battery , or download a game to check its performance
Your phone is a copycat. Sorry.

Moto E extra SIM slot

Can someone tell me how to use the extra SIM card slot of the Moto E? I have a Sprint version and the manual didn't say anything about the extra SIM slot.
I heard that the Sprint Moto E can be used with International SIM. Do I need to do something to unlock it first?

There's only 1 SIM slot... The other slot is for MicroSD cards...
On my Sprint Moto E, there is 1 SIM slot and 1 MicroSD slot on the right and another empty SIM slot on the left. There are also various reports that the Moto E is a dual-SIM phone.
I have some sort of slot on thr left side to (verizon model) therebis some sort of plastic tab and sticker in there, anyone know what its for and whats in there?
edit pulled it out and its just a sticker with the phones info on a tab imei and model ect.
Maybe we could try, here's firmware (5.1.1) of xt1521:
http://forum.xda-developers.com/showpost.php?p=64097186&postcount=87
Although in my case it is a xt1524, but I've also seen the cover and remove a sheet in blocking any attempt to insert a SIM card appears.
Not if you could flash this firmware (6 files has sparsechunk) and firmware xt1524 only has 5 ....
in the verizon model there's a slot on the opposite side, it holds all the FCC information.. I also see where a second SIM slot *could* go, but it has a plastic tab over it (as if it weren't cut out)
The second SIM "slot" on the verizon model (XT1528) is on the same side as the SD card and the first SIM.
It is above the SD card slot and is covered with a plastic tab. The tab can be removed, but the "slot" is covered by part of the metal frame from what I can see.
I took out the plastic cover over the second Sim slot with a box knife. Can confirm there is a second slot on my verizon model but it is covered by a piece of metal. I don't want to go any further but any tinkerers on these forums can have a go at it.

I took the screen off, its held on by really loose adhesive. Second SIM slot has no SIM "reader", just a metal cover of sorts (I'll attach a pic). Too bad I don't have a small enough torx to take it apart more
Glad to see that someone went above and beyond to investigate the 2nd SIM slot. I guess the 2nd SIM slot is simply not populated for Verizon / Sprint phones. It makes no sense to put FCC ID or IMEI in the slot. I guess Moto is just trying to find some use for it.
To answer my other question, I inserted a non-US SIM in the slot of a Sprint Moto E and I was able to use it to send short code while in US (it says it is using T-Mobile's network). So I think the Sprint Moto E can be used oversea.

Anyone swap Wifi (single slot) tray with a dual MicroSD and SIM card tray?

I replaced the microSD card today in my WIfi model of the Tab S3. While I had the single slot tray (microSD card) removed, I looked inside and it looks like the contacts to read a SIM card are in there.
So I wanted to know if anyone has attempted to swap the WIFI model single slot tray with a dual slot Card/SIM tray?
Wondering if "maybe" the internals are in there and some software tweaks to enable it?
I am debating buying a dual tray online and testing it. But I don't want to end up damaging the slot.
I also checked the popular "teardown" fix it type site for the Tab S3 but I didn't find a video on the disassembly.
Thanks

The hardware won't be there even if the sim tray is.

S7+ wifi, sm-t970(128gb/6gb) has pins for a sim card?

Does anyone think there's a chance this tablet has a modem in to that can be enabled by porting over parts of a dump from one of the cellular versions? Long shot but not use to wifi tablets even having the pins for sim card.
i don't think so, if it has been designed to be working without a sim, there's a reason for it. the only way would be to replace the entire motherboard with the t975/t976 version, so you might as well buy the sim version.

Oh I get it, this is just the first wifi only tablet I've had, that HAS the pins for a sim card, I'm not taking it apart, but since it has a 865+ it would be insanely easy if there's a teardown to tell if it has the hardware, since the modem is now a separate chip with this snapdragon, granted you would need to decan the motherboard to do so,
Samsung used the same SIM/SD Card combo tray for all S7/S7 + models.
You'll notice the filler piece on the opposite side of the SD Card side is shaped like a Nano SIM..
The filler is removable and is marked under the black sticker as a SIM slot.
That said, I doubt Samsung is going to include the radio package in a disabled state on a Wi-Fi only model.
The one teardown video I could find of a Wi-Fi only model S7 did not show any cellular radio antennas. I can only see Wi-Fi leads. Definitely do not see any 5G antennas.

Tab s7+ wifi with sim slot and sim connectors.

I just bought tab s7+ wifi (T970). While i was trying to insert microsd card into the tray i realized it also has space to insert sim card in it. First i thought it might just be it so that Samsung doesn't have to make another tray for wifi models. Then i saw sim connectors inside the slot. I tried searching it online,what other people had to say. Most of the people said that there is no modem for it,some said it might be a software limitation. As far as i know the snapdragon 865+ has an inbuilt 4g modem.If there is no modem in it, then why add connectors for it on the first place.
It would be great if anyone with a rooted device can try flashing firmware from carrier,or just check if it was possible to get sim working.
My T870 has the same thing. Instead of producing two different trays, Samsung put a blank where the SIM would go on the WiFi only models (T870 and T970). Just because you can pull that blank out and insert a SIM card doesn't mean it will work in your T970.
You can try of course, but it won't work. Nor will it likely hurt anything.
Yes, the Snapdragon 865+ has a built in 4G modem, but unless it is enabled in the firmware, it won't work. By firmware, I am not talking ROM/OS level. I am talking chip level firmware.
And even then I'd assume there are no 4g antennas in the WiFi model!
This has been discussed before.
The SIM tray is simply plugged with a blank on WiFi only units.
The SIM/SD Card slot is there (most likely to keep parts and manufacturing costs down), but it lacks a 4G modem and does not have any cell antennas.
