Hey guys,
I have a Verizon S7 (not Edge) and I noticed some peculiar quirks, like the fact that Verizon put all their stupid bloatware in it (it's 2016 and carriers are still doing this? The guy at Best Buy told me there was only *one* S7 and you could use it on whatever carrier you wanted)
I also notice the lack of Smart Monitor, which is a feature I was really hoping to use, since it was integrated into the system and it means I don't have to root to do some automatic cache cleaning.
At any rate, since I JUST got my phone, I don't want to void my warranty any time soon, especially given it's so expensive. With Motorola you could root and flash custom OSes, and if there was a problem, RSD Lite was your friend and nobody would know... but Samsung does that whole Knox e-fuse nonsense which makes that not an option.
However, I know about ODIN and was told that I wouldn't trip Knox if I used ODIN to flash between the official firmwares - it's only if you try to root it or modify the system partition that you would do so.
Is there any actual hardware difference between my S7 which has a Verizon logo on the back of the case and one from, say, AT&T or T-Mobile who also use 4G LTE? And if not, could I possibly flash a firmware from one of those carriers to mine? The only thing I can think of that would need to be changed are the APNs in order to use the 4G service - and even then it might not matter if that info is stored on the SIM card anyway. (I don't know much about SIMs, Verizon never used them for CDMA, only LTE)
I know T-Mobile's S7 has the Smart Manager intact while I've heard reports of the other 3 big ones removing it.
Or if a "factory unlocked" variant emerges, could I flash that one to my phone? The guy at Best Buy seemed to imply such a thing existed already. I know there is a GSM unlocked version, but that would be (I assume) the Exynos variant and not Snapdragon.
On the other hand...
http://www.androidcentral.com/yes-verizon-galaxy-s7-and-s7-edge-are-sim-unlocked
So if the APNs sort themselves out anyway, I see no reason why I COULDN'T take a T-Mobile ODIN image and flash it to my Verizon phone. Would that trip Knox or would I be alright? Just want to make sure I don't brick a $700 phone...
I would like to know this as well

Hi all, I have an unlocked s6 edge (925f) living in the U.S. I understand that it will not be officially bundled into the software since it's an international variant, but has anyone gotten it to work through the framework and APKs? When I try it , I'm able to get into the app and all that, but when I try to add a card, it tells me that it can't communicate with the server. If anyone could help that'd be awesome.
Thanks!
Same exact scenario here. 925F, sideloaded the framework and app, can add card, can't communicate with server. Went to Samsung counter at Best Buy, they couldn't do anything. The girl there though did say she had experienced the same scenario with no connection but in an ATT branded S6 which then cleared itself up in a day or two.
Two things I'm thinking of:
1. Flash a US branded firmware (ATT or Tmobile) and see if that fixes it. Though I'm not even sure if they will flash on the 925F version, and/or the flash will lock the phone to that firmware's brand SIM.
2. Somehow try to get the Samsung Pay logs to see where it's trying to connect but I don't think that's even possible without root which will trip Knox which makes Samsung Pay unusable.
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.
Thanks for the link!!

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.

either way orig user solved his problem thread closed
I'm new to XDA and not very expert at Android. I used to use a T-Mobile Samsung Galaxy S6 with T-Mobile as the carrier. I recently bought a used AT&T Samsung Galaxy S7 Edge, and have succeeded so far in getting it unlocked so it recognizes my SIM card. So my phone is up and running. However, it is still an AT&T phone. I don't know all of the ways it is undesirable to use an AT&T phone on the T-Mobile network. I do know that updating software is problematic. I want to make this phone into a T-Mobile phone, so that when software updates are available it asks me if I want to install them and so on.
Now I'm getting into unfamiliar territory. I believe my CSC is G935AUCU1APB4. (This is called my 'baseband version' in the settings menu.) From 'PB4' I get that this firmware is from February 2016, version 4. My model is G935-A and what's in between tells me something about my country and original Android version, maybe. So when I go looking for a late version of T-Mobile's firmware for my phone, would it still start with G935A, or would it perhaps look like G935T (for T-mobile)? Or perhaps G935U (for unlocked?) Anyway, my first big question is what firmware package should I look for and how do I know that is the right one?
After that, well, I have never manually flashed firmware into a phone. I see references to Odin and SmartSwitch and sammobile. Well, shoot. I figure I can learn any of these packages. Which should I use and why?
That's enough for now, thanks for reading!

OK, I have learned a ton in the last couple of days. Bottom line is the easiest way to update OS on an AT&T Samsung is to take it to Best Buy and ask the person at the Samsung counter to do it. I see no reason to believe that it is possible in software to make an AT&T phone look like a T-Mobile phone. And as far as flashing with Odin? What a totally buggy tool! I was NEVER able to make it get past "analyzing files" or maybe "file analysis". When you get down to switching cords from one USB port to another I figure you might just as well change your socks. Finally, there is a TON of crap advice out on the Web.

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.

lol ok.
I hope you guys can help me. I should have come to you all first.
I have S22 Ultra Snapdragon Unlocked Verizon SM-S908U1 VZW/XAA/XAA
Still haven't gotten One UI 5.
Tried to get OTA not available. Tried using Smart Switch, nothing. Tried going to Verizon website. They have posted that you can use their upgrade assistant tool. Didn't work.
So I called VZ tech support. They said i should have gotten the update and transferred me to Samsung tech who had me 1st try and reset my apps. The tech told me if that didn't work to call back. Gave me a ticket number to reference.
Well, it didn't. So I call back and the 2nd tech guy didn't even want to attempt to help me. He immediately told me I had to take my phone to a service center. He told me I could go to Best Buy or U Break. At this point my head is about to explode.
I go to Best Buy. They aren't set up yet as a service center. But when I tell the guy what's up, he tells me it's probably a corrupt OS and to take it to U Break and they can fix it.
When I got to U Break, they acted like they had never worked on an unlocked phone before. I told them I wanted to be sure the flashed it with the Unlocked firmware. They looked at me like I had 2 heads. They wanted me to call Samsung clarification. So Samsung said that all the firmware was the same. That it's the carrier that locks it. So I tell U Break to flash the phone. 4 hours later U Break calls me to tell me my phone will not take the One UI 5 flash. Everything if boots, it boots to One UI 4.1. They said they could leave it that way or mark my phone as unrepairable. I call Samsung back. I get told that they will not go by the word of their authorized service center. That to replace the phone, I have to mail it to Samsung for them to inspect. If they deem it unremarkable, they'll send me a replacement. Turnaround time about 2 weeks! Meanwhile I'm without a phone, my only means of communication. Or I can pay $99 deductible and replace it under Samsung Care. A phone that I've only had since June and I just made my 4th payment on, a phone I didn't Break.
I said screw it and picked up my phone and brought it home. Naturally it was wiped.
Now for my issue. Sorry to be so long winded. Just wanted to give you guys the back story.
I start to load my phone and notice that the "code" not sure the correct term, changed from VZW/XAA/XAA to VZW/VZW/XAA. I lost one of my fonts I purchased. And my phone just doesn't seem the same.
I tried to flash the One UI 4.1 XAA OS using Odin and it didn't change anything and I still can't get One UI 5.
Is my phone now locked? What can I do at this point?
Thanks for your help
My daughter's un-rooted, unlocked S22 on Verizon hasn't gotten it yet either. The unlocked versions are generally about a week behind.
1. Only Verizon and T-Mobile branded models have gotten the Android 13 update. The U1 is Unlocked firmware and will probably take a week or so longer. The only way you'd get it now is to flash to T-Mobile or Verizon firmware, which I don't recommend because they're bloated, lack certain Samsung features, and require a wipe when switching. Also, Verizon doesn't release all of its firmwares so you'd have to flash a version of 12, then upgrade.
2. There is NOTHING wrong with your phone. An unlocked phone on VZW will show VZW/VZW/XAA. If it was showing VZW/XAA/XAA, then the CSC (carrier coding) didn't fully change when inserting the SIM card.
3. Be patient, the changes in One UI 5 are minimal and there are possibly bugs. Wait for the stable release.

Not sure why people flipping out over this. Just relax the Unlocked Phones with no Carrier Firmware installed will be last to upgrade. All the Carriers get priority first. It's always been this way.
