Hi all,
Phone was working fine but after upgrading to Android 7 I'm unable to place calls. it says "Emergency calls only" and when I try to place a call I get " Not registered on network".
- Phone was working fine prior to upgrade
- Tried different ROMs and got same result
- Tried another SIM card. Same problem.
- Used my SIM on another phone. Works fine
I read somewhere that this has something to do with the modem certificate and that the only way to fix the problem is by getting a Z3X or Octoplus box to connect to the phone.
Can anyone shed some light on this? I've been messing around with it for the last couple of days but still no luck...
Thanks in advance!

I don't think it's like that. It may be, but it's not sure.
If OP said that phone was working properly before the update, I think that his EFS partition's got messed up.
If you have a total TWRP backup or an EFS backup, try to restore it.
If you still have no luck, your only option is Octoplus Box or such things.
Second hand phone right?
Mine is second hand phone, as well. 930S. Have had the same issue when I've flashed to 8+ ROM, and moving from no cell coverage area and then back into cell service area. I'm able to to a service search and it will find the towers and upon selection will connect back up.
If I flash to a different ROM, about same issue. As long as I remain in service area does fine. Skip out of the area and I may have to re-search.
I'v flashed different CSC's, no change really, except when I flash an AT&T CSC, then it seems to stay locked on a bit better, though with AT&T CSC I am unable to enter phone codes, so I went back to 'stock' (Korean phone Chinese regions). Stock has no CSC directory present in the root/system directory, which is interesting. I leave the Chinese regions unchecked and the phone finds local towers, US west coast, AT&T networks, T-Mobile, etc, just fine, overall. It's just on very weak signal or no signal that I may occasionally have to do a re-search when I'm back in a coverage area.
Your's sound much more a PITA.
Hi,
I was recently gifted an unlocked ATT S8+ (SM-G955U) which I'm trying to activate to my Verizon account. I've read conflicting information about this, and after going to the Verizon store and calling them directly I'm thoroughly confused.
The rep on the phone told me that the phone is "incompatible" with their network based on the IMEI number. From what I gather, the hardware (and model numbers) on all the major carrier's S8+s are the same and simply have different firmware. I've also read that they're interchangeable. Has anyone successfully gotten the ATT S8+ on Verizon? I'm almost feeling like it's something where I would need to jump through more hoops and speak to a manager to get them to do it, but before I did I wanted to get others input. Thanks!
I heard that the phone will work, you'll need to flash the Verizon firmware onto the AT&T phone.
Thanks Richie. Do you think that Verizon is telling me that the IMEI is "incompatible" because I may need to flash another firmware to enable CDMA? Or are some versions of the S4+ really incompatible on their network.
May there be possible success to get them to activate it anyway?

Do you already have an active Verizon SIM card? Like in another phone?

I do not - only because I'm coming from an S4 (which has the larger SIM card). I had to get a new one.

The IMEI thing and Verizon not provisioning your phone to activate on their network is the ONLY obstacle you have.
All the US S8/S8+/Note8 variants are identical and can be cross-flashed to whatever carrier you want. You can easily grab the VZW firmware and flash it on to your AT&T device, fully converting it, however the IMEI won't be in Verizon's system since your particular phone wasn't sold by Verizon.
Somehow get around that and your phone will be fully compatible on VZWs network.

Don't worry about what Verizon reps are telling you because most often than not they are following a standard procedure. And they only Input your IMEI into a service like this one:https://www.verizonwireless.com/bring-your-own-device/#checkDevice
As your IMEI is for an AT&T phone, the brand model has an A appended at the end (as in AT&T).
However, you should still investigate this issue and try the steps recommended by the other guys. You will be able to use your phone with a VZV sim without reaching to Verizon

I have an AT&T S8 + on Verizon's network, had to unlock the phone, I did flash VZV firmware.
Works for me.
Thanks all for the responses! So it does look like I can do it then, but I just need to get Verizon to activate the new SIM. Think if I could find another phone that's compatible, throw the SIM in, activate, then switch the SIM to the S8+ it would work? (Assuming I've flashed the Verizon firmware on it).
Also, I'm trying to find out how to flash the phone properly. I don't really need root, but I'll take it if its easy. Thinking in my scenario, I'd follow this thread, correct?

Yes, if you can get VZW to activate a nano SIM then all you have to do is pop it in your S8+, and it will work perfectly.
You don't HAVE to flash the Verizon firmware, but you'll won't be able to use certain features such as VoLTE and WiFi calling with the ATT firmware, so I recommend it. Not a necessity though.
To change carrier firmware, follow this thread:

Can't help you with rooting. Sorry, I stopped rooting my phones long ago.

This is great information! I'll call back Verizon and knowing all this I have something to back myself up with to at least try to convince them to activate the SIM (if not, I'll find a temporary phone to activate).
Thank you (and everyone else) for all the help!
I was able to get Verizon to activate the SIM and IMEI of the new S8. When I checked my account online to verify, it shows the correct numbers. Unfortunately, the phone is still not able to make calls or connect to the mobile network.
Following this, I rooted and flashed a deodexed stock ROM/firmware that is compatible with all carriers. This made no difference in the issue.
On the status bar, normal reception for my area is shown. There is no data (LTE/3G, etc.) connection, however. In looking at the APN settings, there are multiple Verizon options to choose. "Verizon Internet" (VZWINTERNET) is what is selected. Under the network operators, Automatic is selected. I tried changing it to Manual, but I do not get an option to select Verizon. Only ATT or T-Mobile. Under SIM Card Status, It's says that I'm on an unknown network.
Any ideas on what I could do to diagnose this? Sorry for all the questions, but I want to be able to get this phone to work so bad!
Thanks!
Success! I was about to give up, but decided to try a few more things.
1) To register a new SIM on VZW, it needs to initially go into a VZW based phone to work correctly. Once doing this, I saw some changes:
- I could now see my phone number.
- Verizon was an option under the network operators setting.
This did not solve my problem, however, as I still could not connect to the network. When selecting VZW, the request would fail and say to try again later. So onto the next (and last!) thing I did...
2) Download VZW firmware and flash via ODEN (The Comsey version, but I don't think that matters). I added the BL, AP, CP & CSC (included in the zip file) using the default options. I found this firmware at the below link and grabbed the latest version. The download was very slow for me (I had to run it overnight), but numerous posters stated that they are a reliable source so I took a chance.

I'm just so glad everything is working now. Thank you so much to all who have responded to the thread to guide me in the right direction! Hope this helps someone else who may be having the same trouble.
I flashed my S7 (930P) to a 930U following these instructions: https://www.youtube.com/watch?v=y0eye-zDOtQ
When I slap my XM sim in my S7, it tells me none detected. The sim is good, I can put it back in the e5 I snagged and it gets coverage immediately. I've tried flashing the modem with the VZW image and am pulling down the 930VC/CCT image now so I can try the Xfinity modem file in case that is the ticket.
If it's not, I'm not sure what my next step is. Any recommendations?
Turns out I'm not thinking straight. Checking the modem file now.
No luck
The device wasn't unlocked and I had the impression the U firmware would release that lock. Not true, still had to get Sprint to unlock.
@eskaryo
I have a sim unlocked Sprint S7 (g930p) on Android 8.0. And when I put in my active xfinity sim almost everything works. Data works, incoming and outgoing calls and texts work. But it won't switch out of roaming and all MMS including group text won't work. So do I just need to flash the firmware you mentioned to get everything working right? And can you flash it on a locked bootloader (which I believe this sprint s7 has)? If so can you confirm the exact firmware I need? Thank you!
I have the same problems with Xfinity service on my s7. This is most likely due to APN settings though I don't know for sure. Sorry I couldn't be more help.
I've just purchased a used SM-G930VL (Straight Talk) phone on Swappa. I requested the SM-G930U, but they apparently sent the wrong model.
The reason I wanted to SM-G930U model was so I could insert any SIM card and it would work.
Questions (and I'm new to Android as you can probably tell below):
- Is the SM-G930VL Verizon / Straight Talk model usually unlocked to ONLY use any SIM card from Straight Talk or would I be able to use any US carrier?
- Is there a way to put SM-G930U firmware on a SM-G930VL phone and is there an advantage to this?
- Will the SM-G930U firmware unlock the phone in case it's locked to Straight Talk only?
- Can I brick the phone for good if I attempt to Flash it and I do it wrong? or is it always possible to bring the phone back from the dead?
- Is there a recent tutorial on how to make the phone accept any carrier?
I tried using Odin to Flash the phone from SM-G930VL to SM-G930V, but was following a 2 year old YouTube video, so the files were outdated and I was unsuccessful.
The phone is running Android 8.0.0 and Knox 3.1, API level 25.

Questions (and I'm new to Android as you can probably tell below):
- Is the SM-G930VL Verizon / Straight Talk model usually unlocked to ONLY use any SIM card from Straight Talk or would I be able to use any US carrier?
: the SM-G930VL is programmed to only work with straight talk sim cards. The phone is factory unlocked as far as i know but it does not allow network connectivity with non ST sim cards.
- Is there a way to put SM-G930U firmware on a SM-G930VL phone and is there an advantage to this?
: Yes you can put the SM-G930U firmware. All US Galaxy S7S are the same hardware wise. The Advantage is that it completely removes everything that ST baked into the firmware.
- Will the SM-G930U firmware unlock the phone in case it's locked to Straight Talk only?
: If in case the device is sim locked to ST, flashing the SM-G930U firmware will not sim unlock the device.
- Can I brick the phone for good if I attempt to Flash it and I do it wrong? or is it always possible to bring the phone back from the dead?
: There are always risks when it comes to flashing any device. When it comes to Samsung devices it's hard to really hard brick a device using and official flash tool like Odin. the device cab get soft bricked but most of the times it's because of user error that it happens.
- Is there a recent tutorial on how to make the phone accept any carrier?
: there are many of them here on the forums but i can try my best to give you a quick run down:
1. First download the SM-G930U firmware from here
2. Download Odin from this thread, Credits to OP on that thread
3. Once Files are downloaded, extract the firmware and odin on the same folder for convinience.
4. Once you extract the firmware, you will have 5 files that each start with BL, AP, CP, HOME_CSC, and CSC (you will need BL, AP, CP and CSC only)
5. open Odin and load each file above in there respective slots, you will be able to see where each file needs to go, note that the AP file will take a few minutes to load as this is the biggest file of the 4.
6. at this point am assuming your galaxy s7 is completely off, Press and hold the Home + Volume down + Power keys together until you see a warning screen about flashing custom firmware, press Volume up to get to Download/Odin Mode.
7. connect your S7 to your PC, use usb 2.0 ports preferably. Let Windows install the drivers (you can get samsung drivers from here, make sure you install these first i.e. before connecting your phone to your PC)
8. Once Windows installs the drivers, on Odin, click START and wait for all the files to flash, DO NOT DISCONNECT THE PHONE until Odin says Pass or something similar.
9. The phone will automatically go to recovery mode and display installing update. It will reboot again and start to boot into android. once fully booted.
10. Once booted fully, you will be on Android Oreo for the unbranded Galaxy S7 with nothing from straight talk and also you will be able to use any sim card on the device.
I tried using Odin to Flash the phone from SM-G930VL to SM-G930V, but was following a 2 year old YouTube video, so the files were outdated and I was unsuccessful.

btw i know this because i myself got a straighttalk galaxy s7 when it first came out. i switched to the unbranded firmware as soon as it was made available and have not gone back to the straight talk firmware ever. the phone behaves like an actual unlocked SM-G930U device and gets updates (albeit a little slower than carrier branded S7s) directly from samsung.
Also once you follow, this go to settings and software updates to get the latest available updates available from Samsung.

Apologies for not answering earlier. I really appreciate your offer and thoughts, however I just returned the S7 and purchased a used S8 instead.

Hey thanks for the thread folks!
I am also (an old) beginner! Followed the instructions (Thank you @micallan_17) and was able to successfully flash stock G930U into a T-Mobile S7 which was supposed to have been unlocked when I bought it, but apparently was not! So, with G930U everything works with my Consumer Cellular SIM (AT&T network), but I can not call out or receive calls! Flashed phone back to T-Mobile stock G930T and took it to a T-Mobile store. They were kind and put a demo SIM in it and it worked to call out. So, the hardware seems to be working. Back to G930U, I have wiped cache and data, but still no calls! Can send and receive text, WiFi works and have 4G LTE functional. It also shows the VoLTE option and WiFi calling, but won't do either. Basically, it is a smartphone that is only smart!
Any brilliant fixing suggestions out there?

Hi, thanks for the reply.
When I call a number, it acts and says it is dialing but it is quiet even with speaker on, and after about a minute it hangs up. No error messages appear. Calling the number from another phone goes to voicemail after a couple of rings, as though the number is busy or off. The Network Mode shows as LTE/3G/2G (auto connect). I also noticed that WiFi Calling that showed up with T-Mobile is missing with this setup, so I misspoke previously.

First an update:
So, after I was convinced that the phone was still locked to T-Mobile, I wrote to the seller and they offered to exchange it. I got the second S7 and it is working fine, still T-Mobile but obviously unlocked! Now I am thinking of flashing it with the G930U ROM, but am not sure if it will affect the unlocking.
My question is just that: I assume the boot-loader is locked; then will going to the Samsung unlocked ROM mess things up? And if it happens that I can not call out with it like the first unit, going back to G930T ROM may not bring it back to the current state!
Has anyone have words of wisdom in this regard?

It should not lock the Device, the U firmware should flash just fine, Flashing the U firmware does not affect the boot loader locked state. make sure the device is permanently sim unlocked not temporary unlocked.

The major benefit (if any) of U (unlocked/carrierless) firmware (from posts in this and other carrier threads) is the avoidage of carrier-specific applications (which are almost universally regarded as *bloatware*). However, because of scripts written by the talented folks elsewhere on XDA, even the most bloated carrier firmware can be skimmed of bloat without the concern that you could be shooting yourself in the foot by not getting a feature that can be firmware-reliant (such as VoLTE or VoWifi). Further, some carriers (Verizon Wilreless most notably) have a stock-only firmware policy (that is, in fact, the biggest ding I have with Big Red).

My S7 (Snapdragon model) is not merely ex-Verizon, but one with a blacklisted IMEI on Big Red; the same would apply to any S7 (the gotcha with a blacklisted IMEI is that you can't take the phone back to the carrier that blacklisted the IMEI in question). The ONLY reason why blacklisted IMEIs happen is going to be contract-breakage (which is commonplace with long contracts - more than carriers want to admit). Still, you CAN take a phone with a blacklisted IMEI to another carrier (in my case, I took it to the the T-Mobile side of Tracfone). Other than that, you can go to any carrier.
Since I have been on the Tracfone side of T-Mobile, I have run T-Mobile Nougat, AT&T Mobility beta Oreo, AT&T Mobility Oreo Final, then T-Mobile Oreo - all without changing carriers, and all on the same S7. (You read that right - for at least two months, I ran firmware technically alien to both carrier AND phone - and it mattered to neither.) What has to be pointed out is that - until the b8 firmware, the ONLY carrier that quibbled about firmware is Verizon - and even that does not apply to their MVNOs, such as Tracfone.) Still, you have to wonder, why does Verizon care - especially since no other carrier did - even with phones under contract - until b8 came along - and that is only with the S7 in update-only mode? (It isn't as if Pie were in the offing for the S7.)

Can anyone at all help me root this phone? I bought it today from Walmart after reading it could be rooted but my varrient SM-G930VL Straight Talk came preloaded with Android 8.0 and all the guides say they are for android 6.0 please help!!
Was on Sprint and decided to change to T-Mobile and now the new T-Mobile SIM Card is unrecognizable/unable to register. This means I am left with no Data/Voice/Text. Checked on a T-Mobile S9 to verify its not the actual card. Works flawlesly, so its not the actual SIM Card itself. 3 months back and forth on and off wrestling with both carriers. Sprint claims device to be Unlocked. T-Mobile claims that its impossible because it sais "device not registered" when I try to make a call. They assured me that this happens only if its locked. Sprint has claimed various times that my S7 (non edge) version is Unlocked for both Domestic and International. Phone was rooted. I was so angry at Sprint you wouldn't even believe it.
Tried flashing T-Mobile FW as the internet suggested. Got it to work and remove the Sprint logo from startup and the super annoying "hands on activation" every 5 minutes thanks to the T-Mobile FW. Problem is that it still does not recognize the SIM Card. Went back to Sprint FW because Sprint rep number zillion said I needed to do a profile update in order to make sure that it got correctly unlocked. I couldnt do this because I had the T-Mobile FW (Oreo 8.0 SM-G930T G930TUVS8CRL1_G930TTMB8CRL1_TMB) and it does not even allow you to do the usual System Updates nor does it allow you to even edit APN's. So I tried to go back to Sprint FW from SamMobile Official (SM-G930P_1_20181203144853_tiy1p0tkd7_fac) and actually got it all installed (all binaries) and now the phone does not display the Sim Card "error" icon on the top left nor the circle crossed icon on the top right. Problem now is that the phone automatically power-cycles in about 2-3 minutes after we start the usual "First Time Use" sequence where you fill your Google User Name and Password and sign the EULA, other first time things, etc. I can't just put in my Sprint SIM Card because I threw that one away as I unsuspected that it would be necessary in order to maybe try to use it to get it past the 2 minute barrier on going back to Sprint FW. Next step would be to take it to a Sprint store and have a Sprint SIM Card inside the phone and see if the 2 minute barrier doesn't happen so I can do this new "Profile Update".
I then tried flashing what I believe to be the non carrier specific official non bloatware Samsung FW SM-G930U. Now the issue is that the version I downloaded from these forums (https://forum.xda-developers.com/galaxy-s7/how-to/g930u-official-stock-firmware-android-8-t3821152) was not able to flash anything but the CP. So Im now going to try the latest SM-G930U which does have the updated BL.
Checked out the forums for T-Mobile and they all assume you can at least edit APN's and have some sort of connectivity. I can't even get my SIM Card working AT ALL. Can't edit APN's because the Sprint FW auto resets every 2 minutes in the new user thing and the T-Mobile FW does not even have the ability to do so. Tried starting on Safe Mode, tried removing the Sim Card and discovered phone wont even boot without it.
Will now continue to check out the SM-G930U latest FW in hopes that this will in fact allow me to flash the non carrier specific binaries which I assume should be able to fix the problem. Trying out https://forum.xda-developers.com/sp...0u-firmware-bootloader-update-device-t3863219. At SamMobile (https://www.sammobile.com/firmwares/galaxy-s7/SM-G930U/BST/download/G930UUES8CSA1/255180/) theres like a zillion to choose from. Any suggestions?
Been getting the fused 8 binary 2 (and other numbers) glitch a couple of times when trying to flash anything. I assume this is due to the BL. Heard QualComm S7's were invincible and I'm afraid its a QualComm because it sais QualComm SecureBoot: ENABLE on the top right of the ODIN Download screen.

Hello
As far as i know you still cannot unlock the Qualcomm boot loader, many have tried and failed and no one is working on this anymore since most S7's sold are Exynos. Samsung did a right ****ty deal with the US networks hence it's so difficult to get these phones to work on another network.
Not only is it just a question of unlocking the Boot Loader the sneaky bastards of US networks has the firmware on the devices constantly checking its official and on the right network, this is why the phone will not work correctly even after flashing unbranded firmware. It's all down to the boot loader and the qualcomm chip.
There is a way to release your phone from it's prison and that is to change the mother board to a Exynos one, apparently this has been successful and the phone will work on any US network. It's a tricky process but it can be done but remember to create an image of your existing EFS partition to flash with TWRP to the new mother board otherwise you will have issues with the phone registering on the network.

So basically I have to get an Exynos version, remove the mother board, and install it on the Qualcomm one.
Why not use the Exynos one instead if I'm going to have to acquire one anyway to do all of this? Where can I get these motherboards without the phones anyway?
Last "carrier" phone I'm buying ever. Next is a Linux Librem phone or non carrier specific type phones strictly.
This is ridiculous. These multi billion dollar corporations essentially just put a virus on your phone and you got to be lucky someone on XDA hacks it or you've been legally locked out of your own hardware; scammed by "your" carrier and that's it. Its completely disgusting they have to try to squeeze every last penny out of all of their victims after they have already so much money.
Its like YouTube wanting to charge 2 dollars a month so you can turn off your screen while watching a video (YouTube Red). Alphabet (company that owns YouTube) is well in the 1 Trillion Dollar net worth range already, but they still need to use these hardcore guerrilla tactics against their "clients" at expense of their physical health to squeeze every last penny out of them like their life depended on it. Phone screen left on generates palpable air-wave toxicity (and pollution for planet as a side effect) as I can personally feel it giving me a headache more than when its turned off.
At least with PC issues you can just format and restart. Imagine if PC manufacturers were like this. Vomitose.
Dell won't claim its "their computer" (like the phone carriers do) as an excuse to lock you out of your own paid hardware if you want to change something you don't like about *your* computer.
I literally remember one of the Sprint reps literally mocking me on the phone snarkily reiterating that it was "Their Phone" as she laughed me off to hold again. We have to basically suck up their corporate legal abuse and let em sort out in hell.
We luckily have a boot looped Optimus phone lying around the house I'm now having to fall back to. Hopefully the carrier did not place an untamed virus on that one.
**** Sprint and every large corporation trying that hard to legally scam their own clients/victims to squeeze out every single last penny out of them like this. **** this "planet" and the "legal system" that allows this. **** the system carrier virus.

I repair S7's on a daily basis, and can tell you that while the mother boards on the G93xU and G93xF are physically identical, if you swap them into the opposite model's case, you will get a MIPI Fail error (will loose signal) under the test command *#0#* due to the charging port/antenna boards being different. And you can't swap those boards either because parts of it are tucked under the screen (unless you're willing to break a screen.
