I bought an S8+ 955FD which seems to be genuine but when I contacted AT&T to get assistance with slow LTE speeds (I contacted them 2 months ago for the same reason when I was using an AT&T branded phone). Of course they ask for the IMEI to verify whether it's an LTE phone and is supported. When I gave them the IMEI they said it wasn't even coming up as a Samsung phone let alone LTE. It's listed as an unknown phone with 2G capabilities. I checked the IMEI on http://www.imei.info/ and it shows that it's a S8+ and everything checks out on that site as it does on my Samsung box.
My sister has an S8 too 955F and when AT&T checks hers, it comes up as a Samsung S8+.
I don't know if my having rooted the phone has anything to do with it (I'm guessing not because rooting doesn't change the IMEI) but could this be a fake? Should I return it?

Very well could be. Where did you buy it? Take a look at this thread.
https://forum.xda-developers.com/galaxy-s8+/help/s8-software-installation-problems-t3639259
If it has a mediatek processor and not a snapdragon or exynos it's definitely a fake.
AT&T does not have anything in their databases about international phones like the F model. When you call them and give them an IMEI of an S8 F model, they will not know anything about it, and their systems won't know what features it is capable of supporting. Ton get Volte working, you will have to flash the ATT CSC https://forum.xda-developers.com/galaxy-s8/samsung-galaxy-s8--s8-cross-device-development/utility-flashable-csc-selection-v1-1-0-t3636739 and keep calling them until you get a 2nd level tech support guy that is willing to go into the guts of their systems and place an IMEI of another ATT phone that has similar features. If you have another similar phone on your ATT account, they can use that IEMI to have their system figure out what features it supports. I believe they used a S7 that I used to have and that got Volte working - for a while anyway.
I have an unlocked S8+ phone Model G955U1 and was with AT&T. In the process of trying to get wifi calling (BTW, they don't provide this feature for unlocked phones, so I dumped them and went with T-Mobile), I asked them to verify the IMEI, they could not find it. Their IMEI data base lists only the phones they sell but not the factory unlocked ones or phones you buy somewhere else. I wouldn't count on AT&T and as ggrant3876 mentioned above, check your processor's make.

Thanks for replying. Funny, I never got notifications that anyone had replied.
Actually someone did add an IMEI for another similar AT&T phone.
Nothing about the phone seems fake, but when I gave them my sister's IMEI for a 955F they said it immediately came up in their system while my 955FD did not.
I'll review that thread to see if my phone would be negatively affected by the ATT CSC.
BTW, what happened to your voLTE that made it stop working?
Gratitudes!!

None of these are applicable *whew*
The seed of doubt was planted when an AT&T rep told me it may be a fake even though I had not previously considered it.

I feel better now, thanks! It shows Exynos 8895 and everything else seemed legit as well. I don't know why I listen to AT&T reps....
I never really liked the Wi-fi calling on my AT&T V20 and even without it, the voice clarity is wonderful.
one way to check is root , real us versions cant be rooted as its a snapdragon , so far our friends in china cant fake an s8 , just by looking at the screen will give it away , but before the years out iam sure they will have a better clone that could fool anyone.international models are always better also faster than the us versions as nd no crap ware from the carriers .
That lack of band 30 could be the issue regarding the slow LTE speeds

not a fake dont worry and no rooting will have nothing to do with it, also you would easily be able to tell if you compared it to your sisters s8! the current s8+ fakes are the same size as the S8 theres nothing + about them haha, they may fool someone who has never handled an s8 or seen one irl but you would 100 percent be able to tell its a fake having handled a real one regardless if its the plus or not
Very easier to know is real or not, if Odin can't detect then it is fake. Fake one impossible can install Samsung own firmware.
I know my s8+ is a fake. I just need to know how to change imei number so I can use my phone. It came from China. He said it's supported by TMobile and at&t. I want to go with TMobile if possible. He sent me the pattern to call and change it,but I don't know what numbers to replace it with.

You cannot buy them for use on Verizon. Straight talk is several different resellers. But verizon no. Verizon is a cdma carrier. AT&T and factory unlocked phones are GSM. For Verizon you'd need a Verizon phone or sprint phone.
People DONT sell fakes on Swappa as its not allowed.

Yes ill stick with att I know they work with st. As far as fakes not allowed we know people lie and cheat and not follow rules so is there some type of guarantee swappa makes that every phone is genuine? They wouldnt even answer my question about what happens when some one sells me thier in contract phone (wich at that point would have a clean imei) and then stops paying thier bill 3 months later and they block the phone? Wich is why I'm only looking at phones saying unlocked there again Noway to prove I guess. there's gotta be one thing to check or get pic of that proves its real

First off as I said above AT&T phones WONT work on Verizon, which is what you asked. Yes they will work on ST AT&T, ST T-Mobile, but will not work on ST Verizon. If you buy it expecting to be on Verizon's network you'll be disappointed. Straight talk is sold across several different networks.
Well if you'd read about Swappa when someone sells there phones they HAVE to enter an IMEI for one and in which will tell Swappa if it's on a paid account EDGE, NEXT, etc. and which is not allowed there.
The only thing that could possibly happen is if someone reports it stolen after selling and In which there's no way to find that out.
I have sold a ton of things on Swappa as well as buying on Swappa.
Also if you would look at a phone listing you would see they have Feedback, which I'm sure someone that has sold a few + phones with no issues I'm sure Your not going to buy a fake or junk phone.
There's no real thing or pic to prove anything. I could sell you a note 1 and make it say it's a note 4 in the software but just a screenshot you might not ever know lol.
Also a bit of a hint unlocked phones cannot save you from that unless your in another country. If you have a dead IMEI on say a T-Mobile phone even if it's unlocked you still cannot use it on AT&T

Thanks for the info! I may not be explaining well I'm not going to verizon I'm wanting to use straight talk who advertises you can bring any GSM phone when I called was told att brand works best. I thought the other was verizon but like u said that's CDMA maybe t-mobile was the other compatible? Idk anyway I'm happy to hear about the contract phone not being issue I had read that could happen maybe it wasn't a payment issue after all. Maybe it had been reported stolen after he bought.

I'm pretty sure IMEI checks for ATT phones tell you nothing about the contract status of a phone, only if it's been blacklisted (lost or stolen)--
TMO phones OTOH will receive the additional information on EIP status, in-contract status, etc.
ATT should be forced to provide the same AFAIC.
You can use CDMA phones on Straight Talk. The kit you buy gives you the network info for CDMA phones and the SIM card for GSM.
When i bought a "new" note edge off Ebay early this year it was sold as a 915F model, When i got it it was a 915T which was ok as
I was a Tmobile customer. However i wanted to update the firmware and i was told to download a run a program called samsung phone info. And I found out that somehow my phone was really a 915A i have no idea how they faked it but it acted like a tmobile

Now for some reason it locks up and reboots on its on and i would really like to go back to the Tmobile firmware that it had. How would i do this? I have been told that its impossible to load another brand of firmware on a phone? Does anyone have any idea how i can but tmobile note edge firmware on
my phone? is it true that i cant switch? and if so how in the heck did they do it when i bought it? I know they must have been good as behind the battery if even has a fake samsung/tmobile sticker with fake imei and serial numbers on it. At least fake compared to what the Samsung phone app tells me the S/N and IMEI are? Any ideas? I look forward to hearing back from you all.

I don't know about your programming problem, but it almost sounds like that phone was cobbled together from spare parts.
Hello!
So I've been going through a saga of getting the right phone and even through googling its hard to decipher exactly what i need given my experience.
I'll provide some details and where I'm at or at the bottom i'll give a TLDR.
I live in the US have AT&T and I want a rooted S7.
Got a S7 for xmas, after doing some research found out that model isn't rootable (SM-G930).
Returned it got one I found was rootable SM-G930W8, said unlocked, and I saw on a few resources it was compatible with AT&T.
Rooted the w8 beautifully, got my new sim card and no signal.
Put in #7465625*638*# and said "Carrier Locked"
Worked with an unlock service, they looked up my phone to tell me exactly what it was, have the code on deck.
Enter code, crickets but possible my sim card doesn't work or i need to try on the stock rom.
Got a new new sim card, no signal. Erased my root and went stock data wipe, no signal.
Tried my best to find stock firmware that lined up with the info the unlock company gave, no signal.
Now, given all that information, can anyone recommend me a model? Just want it to be rootable and work with AT&T.
I'd appreciate any comments on my experience too because clearly i messed up somewhere or the phones sim card reader was busted etc.
TL;DR : I'm USA & AT&T. I want an s7 that is rootable. Had an episode with my previous attempts and would love a guru's advice.
The sm-g930w8 is the same model sold by all carriers in Canada.
Does the phone have a clean imei? Sim card works in another phone?

The old s7 has been sent back so I can't really answer that question.
Nor can I answer the sim card works, because i dont have an extra phone that uses that type.
I did go to the AT&T store to ask if they could check my sim card with an extra phone they have.
Apparently they don't have extra phones ready for that type of nature??? (wtf???)
So I got a new sim card activated from them to see if the s7 would take it, it didn't.
Still just sounds carrier unlocked to me, what service were you using to try unlock it?
Otherwise the G930F is the international model and easiest to mod.
Only concern you'd have is the US uses a different network standard to the rest of the world, so your 3G/4G won't work as well on a non-US device.
EDIT: There also seems to be some root methods for the US models:

So to give more details.
I installed the Superman Rom, put the # in to input the carrier code. At the top, in all caps, above the input for the code "CARRIER LOCKED".
Would the superman rom mess with that? or show bad info? not sure
What i do know is that i factory reset the phone, tried the # to get the prompt didn't work.
Tried a few alternatives, same one with the actual network code in it, the 1101, both didn't work.
The company is "Unlock Scope"
Is the imei of the w8 clean?
The w8 should work with at&t when unlocked.

So I'm not 100% sure but..
When I was originally using the unlock service they needed the original carrier information, which I didn't know, so they asked for the IMEI so they could look it up.
They emailed a full list of details on it and I'd think that it would of been flagged in that process, assuming though.
So the w8 is now unlocked through the unlocking service?
Here's a link to the swappa imei checker: https://swappa.com/esn

no the w8 never unlocked. code never worked.

Edit:
Checked and it came clear.
Was the phone sold as being unlocked? Is the seller able to give you any carrier information about he phone?
Are you able to change the csc by entering this into the dialler: *#272*Phone’s IMEI Here# ?

I know the 930w8 is an exynos and should support att frequencies.

That is weird because I got one for a friend, got a network unlock code,and it works perfectly on T-Mobile and all carriers in Canada.
Maybe there was something wrong with the phone you received? Where did your phone come from?

I got it from ebay.
So, I'll apologize if this has already been dealt with previously, but I just need to verify what I've been told by a friend who knows Android systems (and Samsung S7 phones) a LOT more than I will ever attempt to understand..
About a year ago, I bought a Samsung Galaxy S7 from a 'rebuilder' (my term) who mentioned at the time "... it was ATT phone..", and, yes, when I turn it on it does the ATT circle jerk logo and has an ATT logo on the back of the phone. This was of no real concern to me, because my service purveyor uses the ATT system (Consumer Cellular), so it's worked well enough. But unfortunately, it also has a boatload of 'semi-proprietary' ATT trash in the phone which I'd like to get rid of. To confuse the matter even more, it appears that I cannot 'unlock' the phone because it has not been associated with an actual active ATT account for close to two years, and it APPEARS that now they refuse to accommodate an unlock code for this phone.
So... according to my friend (Mr. Android Phone), I can 'root' this phone to 'factory original firmware' and make it (in essence) just a plain-old-vanilla Samsung S7 without this rather bogus ATT firmware and the myriad of craplets I'd like to get rid of..
So, I'm here looking for "expertise" in such things because I certainly don't want to 'brick' this pretty nice phone, but I also want to get this to a point where there is no association with ATT in any manner. So my question sorta comes down to: "can I root this and be rid of all things ATT?", and "will this allow me to achieve an 'unlock' without having to play ATT's games? (I had QUITE the discussion with an ATT 'support' dude a couple of hours ago when he flatly refused to give me an unlock code so I could simply ATTEMPT to see if Consumer Cellular's T-Mobile service might work better at my home, since CC tells me I'm right in the center of a brand new rebuilt 4G service area).
Does any of this make any sense to anyone? Pardon my ignorance, but if the IMEI # is somehow 'tethered' to ATT and they won't "release" it, how does rooting help with this? - or is this something more like an 'association' of the IMEI # AND the ATT firmware...? GAH!! I'd just like to be totally rid of all this ATT junk and have the freedom to choose whichever service I want.

Hi There that's a lot of words partner! I'll try make the answer easy to understand and I've cut out much of the post so my reply isn't huge.
1. Yes you can install vanilla firmware which will remove all branding from AT&T and you don't need to root the phone to do this. here is the firmware for your device >>here<< You can also use XAS or XAA. You will see the guide and the Odin you need to flash this firmware.
2. This is another version of Odin on this website if you have any issues with the one on Sammobile. >>here<<
3. Unfortunately you cannot unlock the phone unless the original cell phone provider gives you their half of the unlock key as a code to input to the phone. In the UK once a phone is out of the initial contract period it is illegal for the provider to refuse to give you this code whether your still with them or not. I know in the USA you guys gets ****ed over. The original account holder of the phone can ask for the unlock code but not you.
4. Changing the firmware and unlocking the phone to any network are two different things, flashing unbranded firmware will not unlock the phone the network is tied to. They don't make it that easy!
5. As far as i know T Mobile (USA) has also moved to G930U firmware so you could be lucky with a T Mobile SIM working once the phone is flashed with this firmware but don't hold your breath. Check Sammobile for the T Mobile firmware too.
6. IMEI number is tied to the phone so in theory it can be changed after the phone is rooted and you are able to modify the EFS partition but it is extremely difficult even for veterans like me and it causes lots of problems with cell network registration. Leave well alone if you don't want a completely useless device.
Things to make flashing go easier
1. Turn off FRP lock or sign out of the Google account on the phone or delete it before you do anything, you can put that account back on the phone after flashing.
2. If you enable Developer options make sure " usb debugging" is enabled and OEM unlock, not essential but can help when things go wrong.
3. Anything you want to keep, pics media etc back up or move to SD card, the SD card won't be touched when flashing firmware.
4. Please follow the guides on how to flash correctly.
Any other questions please ask.
It should be noted that if it's an ATT phone it's Snapdragon therefore permanently bootloader locked, OEM Unlock won't actually do anything, that setting only works on Exynos.
The only root method for Snapdragon is to use a leaked engineering bootloader to gain system access, and you can only install the leaked bootloader if your phone is already running old firmware. For up to date phones there is no root method.

There isn't a single page when googling AT&T S7 Exynos that backs your claim up. The USA also uses completely different network technology than internationally, using the S7 Exynos in the USA is already known to cause issues with LTE, VoWiFi etc. They'd have to do a hardware refresh of the Exynos SoC if they wanted to support it in the USA, which they ain't going to do a for a 3 gen old phone.

I did google it, I wouldn't have asked for a source if I found something. But it doesn't matter, you're the one making unsubstantiated claims, the burden is on you to prove it. But since you asked for it:
AT&T's website says Snapdragon

lol ok.
Hey all,
I'm looking at getting an Exynos or an HK version of the S22 series. I saw none of the other versions besides the U supports bands 29 and 30 that AT&T uses. Since they seem to be the more minor bands, how much does it matter and how much does the lack of those bands impact service? And does AT&T ban those S22 versions from their 5G networks?
I'm starting to get tired of OP, but I want something I can tinker without having to deal with AT&T's Sammy versions.
Thanks!
AT&T won't support the international models on their network or so various users have said in other posts. You end up locked out. T-Mobile doesn't do this but the long range 5G and LTE band 71 is missing from the international versions which would mean no coverage in any areas using band 71. Either way you are screwed on AT&T and T-Mobile. Don't have any info on Verizon. Best suggestion is. (Don't Do It)

Crap. Guess my only option would be getting an AT&T version and using a paid service to unlock the BL and SIM.
We already tried T-Mobile last year and had a really bad experience with service and network quality, so they're out.
Thanks for the info!
You might want to rethink the Exynos version and look at one of the SD versions that can be rooted.
I am afraid you will not be able to get the bootloader unlocked (I may be wrong there). Rooting is not possible on the US or Canadian S22. I just switched to TMO this year and so far have had no issues. I use their 5G home internet too.

So is that the Hong Kong and Korea versions? Again brings up the question of if bands 29 and 30 missing impacts service and if so, how much.
If I get an AT&T BL unlocked with a paid service, can I root using the method listed in another thread?

I don't see the S22 series in the list yet. So might wanna further research that.
PSA: Unlock Bootloader on Snapdragon Galaxy Devices with SamPWND (Paid Service)
SamPWND is a paid remote service that allows you to unlock the bootloader on Snapdragon Samsung Galaxy devices sold in the USA and Canada.

There are many posts on here attesting to the fact that the US models of the S22 cannot be rooted. The BL cannot be unlocked, so no root.
May I ask what you are trying to achieve with root? Do you have something in mind or do you just want a custom ROM. There are other issues with rooting the phone. Main one is loss of Knox. This will stop the Samsung apps from working. So there is a trade-off no matter what.

There are magisk mods I run on my phone as well as some Xposed mods.
Not terribly concerned about Samsung apps. I haven't had a Samsung phone in years. Last one I had was an S8 and I only got that thru insurance when I lost my OP6.
Understand. Just wanted to let you know that things like Samsung Pay and Health Monitoring will no longer work and this can not be fixed if you change your mind. I did read that AT&T will ban any international phone from their network, so you do not want to go that way if you intend on staying with them. I think there was talk about the Korean model being SD and was missing band 71 (I think). There is no full solution out there unless a way comes along to unlock the BL.

AT&T doesn't use 71, so not a big deal. T-Mo did.
We tried T-Mo in the summer and had a horrible experience. We went running back to AT&T after 3 months.
When you say banned, are you talking about just the 5G or the entire network? I'm already blocked from 5G with my OP phones. I can't say I miss it as I wasn't impressed with it on T-Mo, and LTE does what I need it to do. Outright banning seems like a stupid thing to do, especially as a lot of foreign travelers could very well end up using AT&T while they're here. But then again, it IS AT&T ...
From what I read, AT&T will ban your IEMI if it is an international phone so it will not work on their network. They are the only ones that do this as far as I know.

Check this out. Long read through all the posts, but may be able to answer your questions. There are other discussions on the US models and international models, so just look around.
You ain't gonna win with the U.S. Carriers. They absolutely don't want you rooting your phone on their networks. Why do you think all U.S. models have unlockable bootloader's when shipped from Samsung? Because they demand it. They also know you will try to get around it and when you do they will screw you by banning your device. If you gotta have a rooted phone move to another country lol.
