Flash S7 SM-G930U to verizon - Sprint Samsung Galaxy S7 Questions & Answers

Is is possible to flash the 930u with the verizon firmware?
I need to get VoLTE(Advanced Calling), WiFi Calling, and VVM working on this phone due to weak cell coverage in my home office and all I can find is a clean wipe flash to even root this stupid thing.
I don't understand why this model is so very difficult to root vs most other phones. I thought I'd found a thread to enable it on the 930u variant, but after researching for some time, I'm just not sure.
Seems that moving to the verizon firmware and then rooting it to remove the garbage is easier than running down all these rabbit holes..........

What baseband are you on?

Root and Tethering Question

I'm about to make the move to the S5 from my HTC One (M7). Before I make that investment, I want to make sure I'm not going to be screwed out of tethering. I have an unlimited data plan with Verizon, and live in a rural area, so my phone is my home ISP.
Since I would be buying a phone from an eBay vendor, I have no control over which firmware version would come installed. So here's my questions.
1. Are there any firmware versions for which root is not available? I've looked through various threads, and haven't found a concrete answer on this.
2. If there are firmware versions for which root is unavailable, and I'm unfortunate enough to purchase a phone which comes with that firmware version, does the latest version of FoxFi support the latest OTA firmware?
Thanks!

I think you'll be okay.

Evidently there is at least one firmware version that makes it impossible, for the time being, to downgrade from. http://forum.xda-developers.com/verizon-galaxy-s5/help/downgrade-oe1-t3149085
This brings me back to my second question. Can anyone confirm if FoxFi works on the OE1 firmware?
I was looking for this same info and couldn't find it. Now I figured I'd post the answer.
I still have Verizon Unlimited Data.
I received a brand new S5 today. It came with OG5. I have not attempted to root it. I installed FoxFi and WiFI tethering/mobile hotspot works just fine. I have not enabled "HD Voice", either, and I just tested and verified that I can have a voice phone call going and my hotspot still works. It gave me 44Mbps down/12 up on my connected tablet, while I had a voice call connected.
As an aside, I don't get what the deal is with Verizon pushing HD Voice as a way to have simultaneous voice and data. Simultaneous voice and data (while on 4G LTE) worked on my S4, which didn't even support HD Voice, apparently, and works on the S5 with HD Voice not turned on.
You're good as far as rooting is concerned.
KitKat, and Lollipop up to version BOD5 can be downgraded. Root method here: http://forum.xda-developers.com/ver...w-to-update-to-g900voe1-5-0-keeproot-t3149784
BOE1, BOG5, and BOK3 are the latest Lollipop, and the bootloader cannot be downgraded. A root method for these was finally released a couple weeks ago: http://forum.xda-developers.com/verizon-galaxy-s5/general/root-method-og5-ok3-t3290370

I believe you're all good the latest versions of lollipop are rootable.. and yes if you root it you can fix the tethering. Or even flash a custom ROM I don't think Verizon selling any of the KitKat versions of s5 I think they're all on lollipop. Hope that helps

Switch Firmware,

Hello, xda_developers.
I just got mail S7 Unlocked in the mail that I ordered from eBay, I believe it was a sweet deal CAD $549.99 + tax. I am with Telus BTW. Let's get to the point.
The phone is with Sprint which has bloatware and APN is locked out. I want to flash a new firmware onto the phone without Tripping the Knox. I looked into the 930U Firmware but don't know which one to pick. I looked into the thread: "Bloat free firmware 930U....anyone tried it?" and saw the part about root, so I backed out.
After I looked into the Sprint SM-G930P firmware and saw few different "Regions": SPR, XAS, and VMU. I found"SPR" is Sprint, and "VMU" is Virgin Mobile USA. For "XAS" I am not too sure, but "XAS image has the APN section unlocked". ("Here" )
Afterwards, I found the forum "Found a code...interesting...." and used the code "##BRAND#" and removed the Sprint boot logo, and some bloatware but the APN was still locked out, and still had "Hands-Free Activation".
I need help picking the right Firmware for my phone, which will let me add APN, and remove the "Hands-Free Activation". I do not want or need to root the phone.
The phone is up to the latest update:
Software Version: SG930PVPS2APG1 ,
Hardware version: REV0.6 ,
Baseband version: G930PVPS2APG1 ,
Build number: MMB29M.G930PVPS2APG1 .
I did not want to flash firmware without knowing for sure it will not brick the phone, brand new phone in a long time, I don't want to break it or brick it on the first day.
Aswell, I am not sure if I can flash a Canadian firmware, SM-G930W8 or the Global Firmware, SM-G930F.
Thank you for reading, hope you can help me out.

The 930U firmware will work perfectly fine without root. No bloatware and you can modify the APN's.

the 930U firmware is bloatware free, and I don't have to root the phone? Also does it have the "Hands-Free Activation" or the "Activate this device" in Settings?
It's bloatware free and it doesn't require root. And when I flashed...it simply activated my device and there's no activate device in settings.

alright, thank you very much.
Going to go flash it now
edit: Quick Update, went to flash the G930U files(firmware?) and it all went smoothly. Takes time to register onto network. any fix without root?
edit 2: Just did a factory reset from recovery, seems to have fixed the slow network register
edit 3: The phone seems to run warmer than the sprint firmware, no idea why
Never mind, I am, an idiot.

Congrats on the phone! That is a good deal considering the phone goes for 899 brand new, and I'd assume around 600-750. But with black listing these days I wouldn't trust Kijiji etc.
Your phone should work fine except for LTE. Its missing I believe 2-3 bands for LTE but on the plus side it's the bands that bell/Telus don't really use much like 2600. So if you ever see soneone else have LTE and not you that would be why but, then again the bands you don't have usually are for rural areas

Thank you very much. It's a pretty nice deal, still going on I believe. I don't have to worry about the blacklist. Even without the 2600 band data works great, really don't mind not having a few LTE bands, for the price i got the phone for. With the 930U firmware, it works great.

The U firmware has more/better LTE bands enabled than the Sprint (P) firmware. I strongly doubt it's missing any LTE bands used in Canada.

I believe your correct with the U firmware It shouldn't be missing a band or 2 like it is on the Sprint firmware. But yes about the same price as you'd get it on Kijiji (since there's tax) but it's new and don't have to worry about the blacklist

FWIW - here are the bands that are apparently supported in the 930U firmware. This is band priority list from the LTE section of the ##DATA# menu. Not sure which bands Canada uses, but it looks like the only major one missing might be band 17?

I think the Canadian networks may have started using MFBI on band 12 (like AT&T has). If so then B17 would no longer be necessary in Canada. The best place to verify this might be to post a question about it on the Bell and Rogers forums on Howardforums.
In G930UUEU2APEH thread it is said:
"root with the only g930a method there is right now"
So, this universal firmware can be rooted, right?
Can any one give me the link for downloading the 930U rom for my sprint sm-g930p and are they facing any problem with the same

Did the actual flash fail, or did one or more of the MD5 checks fail? What version of Odin did you use? If any of the MD5 checks failed, you just need to download the firmware again - your download was corrupted. If the actual flash failed, the most common cause is the USB cable/connection. Try another USB cable, and/or another USB port on your computer, and don't move the phone or computer around while it's flashing. Odin is very temperamental if the connection is not perfect.

I'm confused too. Are you wanting to use it on Sprint or T-Mobile? Do you have a sprint account, and did your phone activate on Sprint? I don't have any experience using a non-Sprint sim with this phone/firmware. The only thing I can suggest it maybe do a factory reset and go through the setup/activation with the T-Mobile sim already in the phone. Good luck.
If you're wanting to use both Sprint and T-Mobile on this phone, I'm not sure if that's possible. From what I've read elsewhere, even though this firmware is unlocked, it can only be active on one carrier at a time. I don't think you can switch back and forth at will, without activating/deactivating from one carrier to the other. I could be wrong though, as I have not used anything but my original Sprint sim.

S8 Custom ROMs and AT&T WiFi Calling

Are there any custom ROMs (and CSC files) that allow the S8 to successfully have WiFi Calling and VoLTE on the AT&T network??
I am running RENOVATE ICE 3.0 but you need the Notorious Kernel 1.9 for Volte to work on T. Some kernels do not support Volte, but Notorious does. You also need to flash ATT from the Flashable CSC Selection V1.0.0, and create/edit the /efs/imei/mps_code.dat and put ATT in there. You can also delete the /system/omc/ATT/res directory to get rid of the annoying T jingle and boot screen. You then need to call ATT and ask the friendly customer service person to update your IMEI. But when you give them your current IMEI, they will not be able to find it since it is not a ATT phone. So they will use the IMEI of a similar phone. That will get Volte to work. But WiFi will not as I think the IMEI must match exactly in their system for WiFi to work.
Hello. I'm also trying to figure out the same. How can I unlock the G955U? is that even possible?
Ideally I'd like to get the CSC Patch installed so I can get WiFi Calling on ATT, as I do not have any reception in my area. Any Help here would be appreciated.
Can anyone help here? Thanks.

You can flash csc seletcion after the rom.
That package contains the csc of att and the US generic. That generic is the one that I use and it works volte, wifi calling in tmobile ...
Hi Eddie, would you happen to know how to Root the G955U? its the Unlocked version of the phone. I've followed every step for CF-Auto-Root through Odin, but it fails every time. It seems like the Bootloader is locked? Any help would be appreciated here.

If you mean network unlock, then follow the ToS on AT&T mobile and eventually you will be allowed to unlock your phone. And for you to switch from the firmware of SM-G955U to SM-G955U1, you gotta go to this forum: https://forum.xda-developers.com/galaxy-s8/how-to/rd-carrier-switch-root-snapdragon-t3597473
You will not get wifi calling unless u can provide to att an imei from a device that has wifi calling. Only feature u will get working is volte. It's different them tmobile.

I am familiar with the need for an IMEI from a branded device ..... But I'm not even completely sure that's working for the S8+ like it did for my S7

Well i don't know from experience with at&t firmware but at&t should have wifi calling by default. If not and if wifi calling is an important feature towards you, then the last resort answer you have is to flash unlock firmware onto your device since that's the firmware everyone can use while it supports wifi calling and VoLTE (Voice Over LTE)

Once again, per other threads and myself, simply flashing the att firmware will only give you VOLte. You can toggle the wifi calling but it will say your account doesn't have this feature after about 5 seconds. If u call them and give them an imei number that is to a device that is an att device with the feature it will work. This is different then tmobile which will allow u both without doing anything except flashing their firmware.

Hello all ..... ( and @Tkkg1994 )
I'm still trying to get a definitive answer --- Has anyone personally been able to get an unbranded S8 or S8+ to activate WiFi Calling on the AT&T network (not TMo or others) ??
I'm trying to facilitate an issue with using S8 Ports on my unbranded S7 Edge where we can get VoLTE to work nicely but WiFi Calling will not activate (on the S8 port based ROMs).
I am aware (and have been for quite a while) that you must have an AT&T branded IMEI to get this to work on AT&T. I am also aware that this step is not needed on TMobile or really any other network.
I have tried the branded S7 IMEI that works great on my S7 to activate WiFi Calling while using many (most) S7 based ROMs. I have even tried branded IMEI's from ATT branded S8's and S8+'s .... but I can't get WiFi calling to activate while on any of the S8 port based ROMS (I get VoLTE nicely with many ROMS esp the latest BatMan S8 port ROM)
So to troubleshoot I am trying to confirm that even with the S8 or S8+ that WIFi Calling is or is not a possibilty ??
Thanks

I am no developer, but I believe there are two possible causes in the case of T WiFi failure on Exynos:
Perhaps T requires the IMEI to exactly match as a security measure, and since they cannot use an International model IMEI it will never work.
Or there is something specifically compiled for the Snapdragon process and so when it is extract it will not run on the Exynos.
Either way, it won't work. I posted a LOGCAT when enabling it failed, but it is beyond my capability to debug and no one seemed to be able to figure it out.

Wifi Hotspot by switching firmware?

On the S7 I was able to get my wifi hotspot back on my locked AT&T S7 by odin flashing the t-mobile firmware, it also removed all the at&t carrier bloat, but I lost wifi calling. Is this possible on the AT&T S8. If so can someone tell me which firmware to flash? I have been searching but nothing comes up that is definitive or recent enough to be confident in it.

950u downgrade

Ok so I bought a s8 950U the other night and without thinking of root possibilities I updated everything....including software so I'm running 8.0.0 with experience version 9.0.....now in my research only on XDA forums, because it's the only place I trust for my rooting, I'm only finding things for my version to root as long as Its on nougat...now my question is can I downgrade back to nougat using odin? And can I download any firmware from a mobile to do tgis?

Next question will this unlock my phone?
Reason I'm doing this is because the person I bought it from said it was a cspire phone and I put my cricket wireless Sim in and it works great but I can't get mms to work and it don't give me an option to turn off 4g or lte and where I live turning off 4g/lte gives me better service in my house
Unlock?? As carrier unlock?? Im a little confused on that one...as for the on/off 4g or lte ..sometimes its due to carrier firmware limitations.. and on the mms you may want to check your apn settings.. i know that because i have att and i flash the the 950u1 firmware and i had to setup the apn to get mms and lte service..
Yes carrier unlock and see I was figuring it had to do with the carriers firmware but I found on sammobile a US version but all it said was US TMK and IS USC and i don't know the difference...still learning that part but I needed to make sure that's the one I needed to get before trying to downgrade and I was hoping the rooting would carrier unlock my phone and possibly get it to where I can turn lte on off....
And as far as the apn settings go I've tried crickets apn settings a couple different times and still not working but my internet works fine unless I'm at home and got 2 bars lte but can't get crap to load

Flash the G950U1 firmware, that's the carrier free firmware and make sure your CSC is XAA/XAA
You lost me at the xaa/xaa part

When you look at the about phone..there is a part that show your phone carrier config like(att/att;vzw/vzw) etc..
Xaa/xaa means you wont haave any carrier branding or apps installed ...its just samsung stock firmware..
Alright gotcha ya. I appreciate it.
