[Sprint Samsung Galaxy S7 Questions & Answers] ckb.ckb:
Thank you- I appreciate your help & guidance. But I now realize I phrased my original question poorly. I understand that the carrier's "stock" qualification process is based on the phone's stock specifications listed in a database and those specs are linked to the phone by its IMEI. Changing the firmware doesn't change the IMEI or the database, so the carrier's qualification process will always come up with the same result regardless of the phone's firmware.

So hopefully here's a better phrasing of my question. First, if I flash SM-G930U_B to my Sprint S7, then will it be possible to enable VoLTE on it? Second, if yes VoLTE can then be enabled on it, will it then work with SIMs from any 4G VoLTE carrier or associated MVNO (excluding perhaps some unusual cases)? I guess I'm really trying to find out if this firmware provides a way to get my Sprint S7 to work with VoLTE and therefore useful in the future after all 2G & 3G ends or should I simply get rid of it ASAP. :)
[Sprint Samsung Galaxy S7 Questions & Answers] UPdownLoAD:
To the best of my knowledge, VoLTE cannot be turned on for the Sprint network, regardless of MVNO using Sprint. If you turn it on through settings, it's not authenticated by Sprint's servers because the profile of the device doesn't include VoLTE, so the provisioning server won't enable it on it's end.

Yes, it's time to sunset the S7. T-Mobile is trying to get phones that are not VoLTE certified off of their network by next January. Starting next January, you won't be able to activate any device that's not VoLTE certified anymore (that's both Sprint and TMo networks). It wouldn't surprise me if TMo becomes even more aggressive with this time frame.

OK, I hear you loud & clear & will follow your advice. Thank you again.

Thanks man ...found a fix for my problem and now using the g930u version ...its working great
[Sprint Samsung Galaxy S7 Questions & Answers] didi2021:
Hello ahsankhan01,

I understand you managed to install the g930u version on a previous G930PVPSBCTA1 and get it to work.

Can you please explain how ? (a step by step would be great)

Thanks a lot.

Edit 2021-06-24: No need, it worked like a charm with the rom SM-G930U_B . Also got Hotspot immediately.
[Sprint Samsung Galaxy S7 Questions & Answers] ShadowKurimeki:
I flashed my phone (930P) and now its stuck in a boot loop of booting up until it gets to Preparing your device for first time and then resets and starts over. I used SM-G930U_B-001

Any advice on how to fix this?
[Sprint Samsung Galaxy S7 Questions & Answers] carlylemiii:
I was just curious how you knew it was going through WiFi and not a cell site. Having WiFi on also removes the "LTE" so that doesn't really prove anything. On other carriers you can have airplane mode on and use WiFi calling. You can do that on Sprint with this phone too for calls, but you could already do that with the Sprint firmware. If it's all happening through WiFi it shouldn't matter if airplane mode is on. Oh well. Probably won't use WiFi calling until it stops disabling HD voice, anyway.
[Sprint Samsung Galaxy S7 Questions & Answers] carlylemiii:
Running the 930U firmware and upon boot I'm often getting a pop-up about not being able to make a mobile connection, even though I have service and everything seems fine, and I'm also unable to activate WiFi calling, though it worked for a while (now when I tap the slider to turn it on, it goes through 911 address configuration, and then closes that screen and the slider moves back to off).

Any ideas for either of these?
[Sprint Samsung Galaxy S7 Questions & Answers] PoppNLPatrick:
My question got over looked but do I have to flash through Odin or can I flash through flashfire
[Sprint Samsung Galaxy S7 Questions & Answers] lvpre:
Odin. This is a firmware file and not a flashable zip.
[Sprint Samsung Galaxy S7 Questions & Answers] ssjgoku24:
This is AWESOME! flashed the universal firmware 2 days ago. Much better battery life, no bloatware. I even have better signal at my house. I previously had only 3g, but now get 1 bar lte.
[Sprint Samsung Galaxy S7 Questions & Answers] janocool:
Just flash the rom, all works perfect, my phone is working outside USA, got better signal, no more hands free activation, no more useless sprint bloat, got thetering, recommended. Maybe any solution for the root?
[Sprint Samsung Galaxy S7 Questions & Answers] jiangjun413:
Yes, thanks a lot. I also flashed it on my G930P, it works well. It makes me wondering that if all these s7 with 820 cpu have the same hardware. Is anyone knowing that? How to check the band priority on the 930U firmware? The ##3282# is not working on 930U, but it work on 930P.
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
##3282# works on my phone and I'm running the 930U firmware. Are you selecting "View" or "Edit" after keying in ##3282#? You can select "View" and see the band priority under the "LTE" section. Or are you not even getting the "View" or "Edit" options?
[Sprint Samsung Galaxy S7 Questions & Answers] jiangjun413:
after keying in ##3282#, just nothing happened, I can't get the "View" or "Edit" options. Then it will show connection problem or invalid MMI code.
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
That's strange. Is your phone active on Sprint? Do you have service?
[Sprint Samsung Galaxy S7 Questions & Answers] jiangjun413:
It's active on T-mobile now. Now I have T-mobile LTE band 4 service.
[Sprint Samsung Galaxy S7 Questions & Answers] dgr581:
I'm on Sprint and ##3382# works for me
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
Who knew? Guess ##DATA# is a sprint-specific thing... I always thought it was a universal Samsung code.
[Sprint Samsung Galaxy S7 Questions & Answers] arusiasotto:
Oh thank you sweet Raptor Jesus. All that Sprint Bloat made my brain hurt. Now If only I could root and handle the rest of this...
[Sprint Samsung Galaxy S7 Questions & Answers] rhizomorph:
Hmmm, I'm on Sprint too but it doesn't seem to work for me either. [emoji53]
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
Did you use ##3382# (which was a mis-type from the other post)? It's actually ##3282# (##DATA#).
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
One small chink in the armor...

I have finally discovered a minor shortcoming of the 930U firmware on Sprint. Besides no visual voicemail (which I didn't care about anyway), this firmware doesn't seem to integrate correctly with the Sprint voicemail system. Specifically, I occasionally get random phantom voicemail notification icons when I have no voicemail. Conversely, when I actually do get a voicemail, there is no voicemail notification icon. I really don't talk that much on my phone, and don't get a lot of voicemails anyway, so this isn't a big deal for me. Would be nice if it worked right though...

What are other people's experiences with voicemail? Does regular sprint voicemail/notifications work for anyone on the 930U firmware?

EDIT: As others have mentioned doing, I switched my voicemail over to Google Voice. That will suffice for my needs. I don't get many voicemails anyway, so it's not a big deal.
[Sprint Samsung Galaxy S7 Questions & Answers] rhizomorph:
D'oh! [emoji37] . Ok it works...
[Sprint Samsung Galaxy S7 Questions & Answers] carlylemiii:
Indeed, there is only one American S7, simply with different firmwares that enable different bands.

Hello all, so i read through the entire thread hoping someone ask the question i am about to ask but no one did, anyhow i am on firmware PC5 and wanted to know if its ok to flash to firmware 930U.
[Sprint Samsung Galaxy S7 Questions & Answers] T3chMan1:
Flashed the Sprint version "SM-930U SPR" via downloader/decoder, all works great, very snappy, no boost logo on boot. get LTE+ speeds over 50Mbps, LTE ~25Mbps, also I sometimes use 4G Switch, I use hangouts caller with my Google voice on LTE only. In 4G Switch with "LTE" only enabled get no LTE+ only on "LTE/CDMA auto PRL" switch option.

[Sprint Samsung Galaxy S7 Questions & Answers] T3chMan1:
Find SamFirm software, download latest U SPR firmware and flash all four, use CSC Yom version not Home CSC and you'll be fine, use package disabler to disable rest of bloatware.
[Sprint Samsung Galaxy S7 Questions & Answers] loudang:
Slow LTE speed

Anyone notice slow LTE data speeds? I use Speedtest by Ookla and get results of 1mb to 12mb in LTE but nothing ever faster.

Did the SM-G930U via Odin and running baseband G930UUEU2APG9. Haven't touched any other settings.

Checked band priority in descending order is 25, 26, 41.
[Sprint Samsung Galaxy S7 Questions & Answers] lopeyz:
Ran into some trouble flashing the 930U firmware. First I noticed the AT&T logo come up on reboot. Now I have no service. Found the baseband is G930AUCS2APF2 and model shows SM-930A. Did I flash the wrong file?
[Sprint Samsung Galaxy S7 Questions & Answers] lvpre:
Yes. Make sure you flash the file in the first post on the link to the first post. The file name should be G930UXXXXXXXXXX

THE U is important. You flashed the at&t version
[Sprint Samsung Galaxy S7 Questions & Answers] lopeyz:
That's what it appears but I used the mirror link in first post. I'm downloading it again now. Hope it will let me flash over the 930A...
[Sprint Samsung Galaxy S7 Questions & Answers] jiangjun413:
I find one potential problem of flashing the G930U to G930P. If you are using the unlocked G930P, flashing the G930U Rom would destroy the gcf config, which disable the *#3282# menu and if you still using the sprint or keep the non-sprint sim card in the mobile phone, everything works normal, if you change non-sprint sim and want to activate sprint sim on G930U Rom, the activation would be failed and the mobile phone would be relocked to sprint. You have to return to G930P Rom to activate the sim card and unlock it again on G930P rom to use non-sprint sim card.
[Sprint Samsung Galaxy S7 Questions & Answers] lopeyz:
Now I have a new problem. When I try to flash my phone with Odin, it fails and gives an error code SHA256. Where should I go from here?
[Sprint Samsung Galaxy S7 Questions & Answers] lopeyz:
My issue has been resolved using a modified Odin
[Sprint Samsung Galaxy S7 Questions & Answers] loudang:
Maybe the U update just needed a few days to settle in. Ran a speedtest today and got 98mb down and 17mb up.
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
That's LTE Plus (LTE+). I don't know if it's a coincidence, but since I've been running the U firmware I seem to get Band 41 and carrier aggregation (LTE+) a lot more often than before. I haven't quite gotten 98 MB/sec yet, but I regularly get 50-80 MB/sec, and sometimes a little more. Wouldn't it be ironic if this firmware allowed this phone to get better service on Sprint's network than Sprint's own firmware?
[Sprint Samsung Galaxy S7 Questions & Answers] lvpre:
Does it re-prioritize the bands?
[Sprint Samsung Galaxy S7 Questions & Answers] loudang:
I have not changed the band priority as it came in U.

Mine is (1) band 25, (2) band 26, (3) band 41, (4) band 12, (5) band 2, (6) band 4, (7) band 5, (8) band 3, (9) band 1, (10) band 8, (11) band 7, (12) band 38.
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
No, the band priority is the same. It just seems like I'm getting Band 41 a lot more now. Maybe the signal strength thresholds that tell it when to change bands are different in this firmware. Or maybe they've just turned on more Band 41 around me lately. :)
[Sprint Samsung Galaxy S7 Questions & Answers] heathmcabee:
Yes if u were on sprints it wouldn't even be activated without a msl edit.
[Sprint Samsung Galaxy S7 Questions & Answers] MattN03:
Just flashed 930u using Post 1 as my guide. Phone & hotspot work perfectly. Thanks!
[Sprint Samsung Galaxy S7 Questions & Answers] Oakley707:
Did the same. I messed with the root for Sprint just to get the hotspot working only to find out it didn't work with the modified kernel / APNs. What a mess.

Found this thread and just flashed the latest firmware and had the phone completely operational in less than 30 minutes with the hotspot completely functioning. What a breath of fresh air. This is just simple.

What's the best source for S7 Sprint Stock Firmware to undo?

I used this forum for Verizon here.

and this firmware

SPT_G930PVPU2APF2.zip (MD5 hash A463543B398CE49FD7F5DE97DF456AB3) (Sprint Samsung Galaxy S7)
[Sprint Samsung Galaxy S7 Questions & Answers] lvpre:
Yeah. Just put all the files in odin and hit start
[Sprint Samsung Galaxy S7 Questions & Answers] myphone12345:
This is highly annoying. Is there any way to say root the device, re-unlock the phone, then unroot it or something without having to flash back the P version?
[Sprint Samsung Galaxy S7 Questions & Answers] kreizyidiot:
Anyone experience any battery drain or any battery issues? I was on the ATT thread and saw that after flashing the U firmware, people are going back to the regular ATT due to battery issues.

Also, does anyone know how to navigate to the start up manager? On the stock sprint rom, there seems to be a start up/auto run manager for me to disable some of the apps to run on reboot. I can't seem to find it here.
[Sprint Samsung Galaxy S7 Questions & Answers] T3chMan1:
Haven't had any issues with battery life, getting about an hour or two more of power life, I also used Samsung package Disabler and disabled slot of apps "97" of them. Also, if anyone wants to install stock firmware, remove sim card and disabled all bloat and any boost/sprint installers then reboot and insert sim card and provider apps won't be installed.

Official firmware up on Sammobile

I have been waiting and wondering if the "U" firmware would ever be posted on sammobile.com, and if finally is! :D Now we have an official/legit source for this firmware.

http://www.sammobile.com/firmwares/database/SM-G930U/

Interestingly they have carrier specific versions. Not sure if there's actually any difference in all of them. Here's the Sprint one:

I did on the pg9...peh Was fantastic though...I ended up going back. Pg9 sucked battery like crazy for some reason. Maybe the next update will be better
[Sprint Samsung Galaxy S7 Questions & Answers] bigblue206:
Anyone actually try the Sprint Specific file from Sammobile yet? Wondering if that would help solve the voicemail problem.
[Sprint Samsung Galaxy S7 Questions & Answers] skunkenstein:
I would be interested in seeing if voice-mail is working as well..
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
I actually flashed the Sprint specific version just to see if it was any different that what I already had. Unfortunately it's not. Nothing that I could find is any different than the original U firmware. Specifically, no visual voice mail, or any other sprint apps for that matter.
[Sprint Samsung Galaxy S7 Questions & Answers] bigblue206:
Thanks, I am still a noob when it comes to flashing these and wanted to see if anyone else had any problems with it before I took the plunge.

Do you recommend one file over the other?
[Sprint Samsung Galaxy S7 Questions & Answers] matrx10503:
Hello all U users. I am debating flashing, but the root thing.

I have g930p (sprint), but unlocked for GSM.

What is the issue blocking root?
[Sprint Samsung Galaxy S7 Questions & Answers] bigblue206:
Finally took the plunge and am very happy so far. I have the Hotspot unlocked ,which was the only reason I flashed it, and everything seems to working great. Battery life seems to be around the same. I used smart switch to restore my apps, messages, etc, so my phone looks exactly the same as before the flash.
[Sprint Samsung Galaxy S7 Questions & Answers] matrx10503:
Nevermind, i've decided i'm not going to flash the U f/w until root is figured out.

I ended up just downgrading my f/w to fix my hotspot issue.

Can anyone help me out with Google Voice, it seems like I am setting it up correctly but I am not receiving any voicemail. It keeps telling me that I have to call a certain number and enter a code but when I call the number nothing happens
[Sprint Samsung Galaxy S7 Questions & Answers] elliwigy:
so i need to go back in firmware (sprint firmware) root the device so it can be unlocked then i can flash the U firmware and it should work with ANY carrier?
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
Yeah Google Voice still has the wrong dialing codes for Sprint in their setup instructions. I think if I remember correctly you can use the *28 code followed by the Google Voice voicemail number. This will make your phone roll to Goole voicemail if you either don't answer (No Answer), or if you're on the phone when someone calls (Busy).

---------- Post added at 03:09 AM ---------- Previous post was at 03:01 AM ----------

You don't need to be rooted to flash the U firmware. You can simply flash it and then do a factory reset. Then it should activate on whatever network your sim card dictates. So if you have a Sprint sim, it will try to activate on Sprint, verizon sim, it will try to activate on verizon, etc.
[Sprint Samsung Galaxy S7 Questions & Answers] elliwigy:
ok, trying it now with my Verizon sim.. i didnt perform an fdr i was like wth lol..

so on U firmware put any us based sim and fdr and it should work?

---------- Post added at 03:19 AM ---------- Previous post was at 03:14 AM ----------

ok, didnt work.. can it only be used on gsm?
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
I have not used mine on any other carriers than sprint, but from what I've read in other forums, it was my understanding that it should activate to the sim's carrier. You said you didn't do a factory reset, right? I would give that a try, if you haven't already. If that still doesn't work, you'll have to do some more research to see what you have to do to make it work, but in theory you should be able to use it on any US carrier. There may be some other hoops you have to jump through though.
[Sprint Samsung Galaxy S7 Questions & Answers] elliwigy:
I put my verizon sim in and performed a fdr and it still said invalid SiM
[Sprint Samsung Galaxy S7 Questions & Answers] Cooljb:
Interesting. Apparently there's more to it then. Maybe it has something to do with the IMEI number of the phone - maybe it has to be registered with Verizon. Sorry it didn't work out. As I said, I have not tried this myself, so I don't have first-hand experience making it work. Hope you are able figure it out.
