Bought Fake G930F - What now? - Samsung Galaxy S7 Questions and Answers

The phone was supposed to be new but when it arrived the seal was broken.
It shows G930F on the sticker and the ROM installed is 7.0: NRD90M.G930FXXS4BQC1. Phone Info and CPU-Z both show a Snapdragon 820 installed and the bootloader G930TUVS4BQC1. Both of which indicate to me it is a SM-G930T in reality. Am I correct? There are no OTA updates available.
Is there anything I can do to make the phone usable here in Europe and get the latest security patches or a newer ROM? Phone service is unusable atm.
I still don't have my money back from Paypal, but the Ebay seller already told me that they decided in my favor and how I scammed him (funny, he?). How it looks I can keep the phone, but I would like to know if I can make it usable some how.

Nightmare! Anyway if it's a T Mobile snapdragon (it definitely looks like it) you'll need to install T Mobile firmware from Sammobile of use SamFirm Tool. Flash with Odin obviously and make sure OEM is unlocked.
**This is important** so pay attention. Your boot loader version is an old one (U4) which is good because it means there's more you can do with it and the phone should be fairly easy to root. If you just type "G930T" into Sammobile firmware search you'll see there are lots of firmware updates after the one installed on your device. Once you upgrade a boot loader you cannot go back.
There's quite a few threads here about USA devices working in Europe, for the most part the phone will work but sometimes people have issues with 4G or LTE due to the radio band differences in the USA and Europe (regional difference).
So flash official firmware (stick with nougat 7.0 if you want for now) and see how the phone works, then basically go from there.

Thank you very much, for the answer!

Why do I exactly need the T-firmware? I can disable OEM lock on the F-firmware and I can factory restore without issues. Afaik I still don't get updates, if I'm not in the US with the T-firmware. The problem I have is bad connection and no security updates. If I read correctly in other threads there might be no way to fix the connection problems. I think people flash the U-firmware over 930T and 930A. I'm not sure which one would be best.

Is there any danger this happens automatically if I flash another ROM?

Yeah, I kinda need band 20 here for 4G to work without problems.
Edit: According to Frequencycheck there shouldn't even be a incompatibility (in theory).

I was able to flash the G930U firmware and bootloader (v4)* and OTA updates are working. Reception is still very flaky. Sometimes I get full bars, mostly it's at 1 bar. According to several websites the frequencies and bands are fully compatible to my country and provider. Strange. (My older phones all worked better.)
So now I wonder if there really is any reason to stay on v4 bootloader. Since this is the Snapdragon version I can't install Lineage and root seems to work even in the latest bootloader according to this thread: https://forum.xda-developers.com/verizon-s7-edge/how-to/root-s7-s7edge-oreo-nougat-t3819616.

OK good T or U is good on that device.
Changing the bootloader won't make any difference to the reception, the phone is built to work in a different region its as simple as that. It will never be 100% functional in another region as the bands are hardware and firmware specific. As you've found out the firmware is the easy part but you'll need to change the motherboard to resolve the incompatible hardware issue, it's simply not worth it.
Also, all these other threads saying it is possible to get it 100% working are talking rubbish. If it were that easy everyone would be buying Sammys from South Korea where they cost peanuts and then just flash your region firmware. There are commercial reasons (like all smart phones) the same device is built for different regional markets.
Its so annoying that people post such crap on these forums, very difficult for newbies to follow advice.

I feared as much. At least I got my money back now except shipping fees. I can still use it as a mobile computer for browsing and some applications. For a useful phone and navigation device I'll have to buy another one.

Can stock firmware be flashed to D850 through PC like the international version ?

Hi..
Since I live outside of the US, this is the only way to install system updates as far as I know (OTA doesn't work), so I'm wondering, is there are any special procedures that should be taken before flashing the firmware? There is a dedicated thread for how to do that on the D855's forum (Link http://forum.xda-developers.com/showthread.php?p=53452990#post53452990) ,however, the mysterious lack of any threads like that in D850 forums has made me worried a little bit, especially that I've read somewhere that non international versions of the device comes with a locked boot-loader which can complicate things sometimes (The one that I have is network unlocked (obviously)).
Sorry if this is a dumb question or something like that, but I've never used/owned any of LG devices, plus the device is for my little sister so I can't take any chances even with something like soft break since it will totally freak her out, plus I've tried to use forum search box many times before asking, but it totally failed me however.
Thanks in advance.

Yea that model you'll use the tot method. But you cannot get lollipop unless you have an active att sim. Or use a custom rom sadly.

Pretty much you are stuck with doing custom ROMs. The only TOT file that I'm aware of floating officially or in the wild for the D850 AT&T is for KK. OTA is the only way to update past KK in terms of official updates, which of course requires an AT&T sim card.

Thanks for the replies..

Does it suffice to only have an active SIM in order to "activate" OTA updates and then download them through WiFi? Or must the OTA update also be downloaded exclusively through AT&T's data connection? Because they sell AT&T SIM cards on eBay with international shipping for pretty cheap prices, and of course I'll have to activate some prepaid one-time plan that includes global roaming (unless it is already embedded in all plans and you have to pay extra only when you use calls, data or SMS etc, I'll be sure to check their website if you tell me that it works). Global data plans however are too expensive to pay for for such a thing, 800 MB plan costs around 120 $, So my only practical option here is to update through WiFi, while AT&T SIM is inserted (if that works).

I think the flashing guide that I've put the link to does contain what seems to be D850's Lolipop ROM, you can find it here:

Am I missing something?
Thanks.

Flashing 930U on my T-Mobile S7?

I just heard when the August security patch released on the 930U today two very interesting things. I wanted to see if they were true:
1. All Galaxy S7s released in North America are actually the exact same hardware model, but because of different firmwares not every LTE band or software feature is activated. For example, a Verizon S7 that is listed to supposedly only have CDMA and Bands 2, 3, 4, 5, 7, and 13 (which is pathetically lame by the way) can be flashed to the 930A software and work perfectly on AT&T.
2. I can flash the 930U software on to my 930T phone and turn my T-Mobile phone into a 930U. I'm still making payments on it and I'm not sure if this would unlock it or not, I don't care, I plan on paying it off and unlocking it through T-Mobile anyway. I'll get White Pages back which T-Mobile took away for their stupid paid service, and I can download the August security patch and from now on get my updates directly from Samsung.
So is this possible for me to do? I'm new at this whole thing. Also, if I did flash my phone into a 930U, will that affect me unlocking it through T-Mobile later on when it's paid off? Thanks for the help.

If the bootloader is higher than currently on the SM-G930T then it should allow to a flawless flash.

Yes, I just found out yesterday about how the T-Mobile S7 is currently the only version that has a different level bootloader than everyone else. The day had come when Verizon users can now do more with their phones than T-Mobile users, what a shame.
Could a pending upgrade be in store for the 930U firmware so it's possible to do again?

Probably maybe. I would say to hold on on updated the TMO S7 in hopes that the SM-G930U gets a bootloader higher that what currently TMO has and allow you to flash. Since it's unlocked then updates maybe 5% faster.

Thank you, I wish I hadn't found out that I could do this only yesterday. I'm still fairly new with the whole concept of flashing software, I know what it is but that's really about it. Hopefully I'll be able to flash the unlocked firmware on here and get those missing features back.

Can I root my Samsung S7 and gert rid of "all things ATT"..?

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.

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:

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.

looking for "before-i-buy" details on the different versions, for using on T-mobile

looking for "before-i-buy" details on the different versions, for using on T-mobile
cant seem to find exact details on in2013 / in2017 / in2020 / in2025 but i have (obviously) seen those references around while trying to research the different versions
i presume 2 of those 4 versions are international and the others USA, please do correct me if i'm wrong.... and based on the descriptions from people who are "selling" the Oneplus 8 phone(s) all of these appear to be T-mobile compatible
i've seen that there are both locked and unlocked versions of the USA models.... and i also have easy access to some unlocked international models locally from 3rd parties.... which leads me to some questions:
Question #1
is the T-mobile OTA blacklisting for bootloader unlocking limited to sprint/t-mobile models, or would an SIM-Unlocked USA model also end up blacklisted for bootloader unlocking?
Question #2
is unlocked International a bad idea for usage on USA T-mobile due to availability of bands?
appears 4g and 5g would be accessible, but i don't know to what extent the coverage would be hindered (which i've noticed can be anywhere from non existent to severe cell frequency mismatch between brands / regions / models)
Question #3
am i looking at any kind of "technical difficulties" outside of OTA block, by bootloader unlocking on OnePlus? i am very new to the brand, coming from Samsung in the era before they were locked by default :silly:

Hi,
First of all, there are 4 versions of the OP8 :
IN2010 (China) IN2013 (EU) IN2015 (US) IN2011 (India)
The OP8 Prois the same, but with IN202_ instead of IN201_
There are also brand specific version: Verizon and T-Mobile. Those version are a pain (as I heard) to update even by the official version. There are some workaround to SIM unlock those, but they'll still be a pain to update and root. If you succeed in rooting that you'll be blacklisted for OTAs on those versions.
The USA version is different, not a pain to root or to OTA update, you keep OTA when rooting. In short that's the phone OP intended you to use. It's 5G, but not millimeter waves or things like that. I couldn't test 5G yet since I don't live in America, you have to scroll through the OP8 forums to find your answer.
And there is no "international version". Don't be fooled, International version is a way to lure buyers in buying chinese version but flashed with OxygenOS global. You'll buy the chinese version (with potential band mismatch), it's cheaper but you'll have issues with G-Pay and 5G (even 4G in some countries).
So #1: Carriers phone not only blacklist you when unlocking bootloader, they try to make it impossible for you to unlock it. Idk if it's the same with unlocked SIM (but I don't think so)
#2: Since international is in fact chinese with global software (and not chinese specific) I highly recommend you not to buy it (even though the price looks sexy)
#3: Unlocking bootloader requires you to wipe your phone, otherwise no issues if you follow the instructions. If you flash a ROM or install magisk modules then the stability of your phone depends on the dev's work and not the OEM anymore.
I might be wrong with the Carrier Devices banning unlocking bootloader since I'm not from America so search more on the internet.
Hope this helped, have a good day :good:

there is definitely an IN2017, it shows on phonearena and gsmarena spec pages, but in the USA each carrier has a designated model number within a same phone model (like 900P 900T 900V) so that might be what's going on with IN2015 versus IN2017 (i'm guessing GSM model versus CDMA model)
There are also brand specific version: Verizon and T-Mobile. Those version are a pain (as I heard) to update even by the official version.

there is definitely an IN2017, it shows on phonearena and gsmarena spec pages, but in the USA each carrier has a designated model number within a same phone model (like 900P 900T 900V) so that might be what's going on with IN2015 versus IN2017 (i'm guessing GSM model versus CDMA model)

You're right, I forgot to put it, IN2017 is the CDMA.
And CDMA are modified versions of the IN2015. That's why you can't use the same cases for CDMA and GSM versions. They added in the phone, the hardware to make their 5G technology work. So CDMA and GSM technically are all American (since they're located there), but they're different, especially for OTA. It's not OP that provides updates for CDMA phones, that's T-Mobile or other carriers, and I heard people here complaining the updates are slow to be available. I don't even know if Android 11 is available for them yet.
That's why I advices you to buy the IN2015
There is a MSM tool for t-mobile that is up to date with the latest firmware, 10.5.20.

i've always been a samsung guy, i dont know if you're familiar with samsung tools, but, based on what i researched last night, it sounds like MSM is effectively "odin" right?

It's kinda like odin, except it's better. MSM can fix just about anything except a hard brick.

sounds wonderful to me i'm honing in on the decision to buy, just having a hard time finding non-retail prices, other than Swappa
would you recommend getting the T-mobile and converting (which effectively means unlocking? lol) or does that come with caveats avoidable by just buying one already unlocked?
it sounds like there's no difference but ughh... idk i'm in information overload mode trying to hit the ground running lol
If it was up to me, I would just buy the pro model if you can afford that. I ended up buying through tmobile to finance mine and had my device sim unlocked so I can unlock the bootloader.
I have IN2017 on Tmobile and would recommend it. The Tmobile vendor rom works better on their network for obvious reasons, for example 5G standalone doesn't currently work on the Global OOS (oxygen OS) roms.
To answer your specific concerns:
#1 I've never heard of Tmobile blacklisting anyone for unlocking or rooting. Just make sure the imei is good if you buy used. Use a legit site like Swappa.
#2 Yes avoid the "international". Stick to IN2015 (Global) or IN2017 for use in the USA.
#3 Bootloader unlock on the IN2017 requires a clean esn/imei. You fill out a form and Tmobile gives you the unlock code a week later.
After bootloader unlock you can easily root with Magisk or flash pretty much anything. On my 2017 I've ran the tmobile rom, OOS10, OOS11, and gone back and forth.

i have a feeling if i walk into a T mobile store and ask them for a bootloader unlock code form, they're going to look at me like i have an alien doing a handstand on my shoulders...
havent met a single employee yet who could figure out why putting a T mobile sim in my old Sprint phone is a bad proposal for coverage lol my hopes are pretty low with them.
could you tell me a little more about who / where / how to acquire the form from?

Hi,
First of all, there are 4 versions of the OP8 :
IN2010 (China) IN2013 (EU) IN2015 (US) IN2011 (India)
The OP8 Prois the same, but with IN202_ instead of IN201_
There are also brand specific version: Verizon and T-Mobile. Those version are a pain (as I heard) to update even by the official version. There are some workaround to SIM unlock those, but they'll still be a pain to update and root. If you succeed in rooting that you'll be blacklisted for OTAs on those versions.

They say you won't get updates, but my phone has wanted to update for over a week now. Maybe security updates aren't affected? I have IN2017, unlocked bootloader and rooted.

yes yes i'm re-quoting the post lol
are you saying that OxygenOS is the global rom? also, can you clarify what is being described by 5G "standalone" ?
just got my IN2017 and it's on oxygenOS 10
it is unlocked and my account is Sprint (and will remain that way) but sprint's system was too slow to reflect that this phone was activated on the account, so the T-mobile store wasn't able to put a T-mobile SIM in it (yet)
...with that said, the phone says 5G is connected and speed tests are.... pretty bad... barely meeting mid tier 4G standards... how can i definitively confirm or deny if i'm on the global rom

Bro....
You will need to flash it. It doesn't come preinstalled on Sprint\tmo.
I'm using your exact setup. I too have the Sprint sim in my Tmo OP8
If you are on 10nand want to go to global, there is a thread on here that will take you through the process.
Follow the guide carefully but confidently. It does work and will not brick your phone.
You will convert to global a10... I had issues with cellular signal after converting.
HOWEVER, after upgrading to A11 global rom (local upgrade) everything works perfectly.
I'm on OOS11 Open Beta 3 with sprint sim on the IN2017.

based on what everyone's said so far about the global rom, i have zero interest in it.... i am merely trying to understand if i am on that rom now as a result of possible shady dealings from the seller on Swappa, based on how the post i re-quoted was worded. it threw me off.
but from the sound of it, i get the feeling OOS is not the global (or at least the version i have installed is as it should be -- stock TMO)
and i'm rapidly falling in love with this thing... it's so &@#%*$^ fast

Don't know what you've heard about global but it puts Tmo stock to shame
Simple answer. Buy the phone from oneplus.com. I did and have had no issues at all on T-Mobile. Trust me, with any OnePlus devices, you absolutely want to be able to root right off the bat and install viper. Audio tends to be a big problem with oneplus phones, and only viper seems to solve the issue.
The phone is $600, and a bargain at that price.

Just look at the version on the about phone screen. The TMobile software builds end in IN55CB (latest is 10.5.22.IN55CB), and the global roms end in IN21AA.
About the 5g standalone, that means you can connect to the 5g signals alone. This only works on the Tmobile rom right now. You'll see NR-SA in apps like signalcheck or network signal guru. The alternative is NSA (non-standalone) 5g where the phone has to be connected to a 4g signal at the same time for 5g to work. This gives you 5g speed but with higher latency and it uses more battery. It's just like when Sprint 4g came out but early phones needed to stay connected to the 1x signal as well.

Question Flashing unlocked firmware over carrier firmware?

Like the title says, is this possible and can it be done without wiping user data? Thanks.
Probably not worth the trouble. Always assume you will lose the data and back it up redundantly.
I thought there be a night and day difference when I got the unlocked N10+ N975U1 vs the AT&T variant N975U. There wasn't. The unlocked version actually had some bloatware not on the AT&T variant
Easiest and safest thing to do is package blocked the carrier bloatware. Verizon does some screwy modes to their devices so getting rid of that be nice. AT&T does not, that surprised me. Some users might like some of the AT&T apps.
It was successful, thank goodness. See my follow up here https://forum.xda-developers.com/t/f721u1-firmware-now-available.4484639/
Notice much difference?
Yeah the main stuff are:
1. Rcs with jibe server works now. Before it used att server so it wouldn't connect properly with other users
2. System updates come directly from Samsung instead of att

Don't use either.
Updates is one of the first things I disabled on my N10+'s. One's on Pie, the other 10, I prefer Pie though. Once Google started rolling out scoped storage I bailed.

AT&T/Samsung have a nasty habit of screwing up older devices with firmware upgrades. Just had a pair of Buds+ screwed up like that a few months back, now they need the firmware rolled back*. S4+, same deal a few years back, but bootloader was updated too, no rollback.
If an OS is running fast, stable and fulfilling its mission... I let it be.
*I have 2 new pairs of Buds+, they sound identical and like my original pair use to, grrrrr.
Went with them because Samsung's newest release lack the features I want. Rather annoying.
The Buds+ have a 11 hr run time, light, don't fall out and sound good.
Sorry I should've posted my question here, instead of creating a new thread.
I recently purchased a flip 3 and am on a payment plan, tmobile won't unlock my phone unless I pay it off in full. Is it possible to flash the default software of the unlocked model so I can get updates from Samsung and still have my sim work? I'm not switching carriers, do I need the tmobile version of firmware for data/phone to work if the phone isn't unlocked?

Phone service will still work perfectly fine on U1 firmware, but you may lose lose some carrier-specific features like wifi calling etc. But.... the U1 models don't always necessarily get faster updates than the carrier models. For example, with the most recent update, the carrier model got it 2 weeks before the unlocked model. So if that's your only reason for wanting to change firmware, I'd advise against it.

What I'm concerned about is tmobile eventually stopping the updates way sooner than Samsung. The carriers don't usually update a phone as long as the vendor so to avoid that I would rather not use T-Mobiles version. Thanks for the reply, it was very helpful.

Incorrect. Every single model's lifespan for updates has always been the exact same, whether U or U1
I downloaded the unlocked firmware via Frija for SM-F711U1 / XAA and flashed it onto my At&t unit using patched Odin. Lost my data since the install didn't work without flashing CSC but booted up and working just fine now. No At&t bootscreen or bloat
