Unlocking More Bands?

Hey!
From what I've read online it looks like all S7 Edges are built identically which means that the bands must be controlled by software. Are there any firmwares, patches, or tricks that enable other bands? I have a Verizon S7 Edge on T-Mobile so I'm mainly looking to unlock band 12. I saw this post: http://forum.xda-developers.com/ver...e-flashing-sm-935u-firmware-verizon-t3415145/ but im not sure if that will unlock the bands or not. VoLTE and WiFi-Calling would be a plus.
Thanks.

So you mean like flashing the u firmware or something

I believe that is what this post describes: http://forum.xda-developers.com/ver...e-flashing-sm-935u-firmware-verizon-t3415145/ but I dont know if that will actually unlock the bands or not. Have you tried it? Will it actually unlock the bands?
Thanks.

I haven't tried this but my s6 edge works for my gf on metro and it's a Verizon phone with of1 firmware. I don't see why the u firmware wouldn't work for you.

Flashed the U Firmware. It didnt unlock the bands. Any other suggestions?

Maybe now that you're on the U firmware you could flash the T-Mobile firmware? Not sure if it would work or not, maybe you'd be willing to try. Make a backup just in case...

I do belive the band's are controlled by the baseband/radio file in the updates, of course most of my experience is with the ENG bootloader on HTC devices so I think for Samsung it's either modem or pda....more experienced members can correct me if I'm wrong, so feel free to jump in

Do you think flashing the T-Mobile firmware would help? I posted in the other thread asking if it would work but if flashing firmeware replaces everything (bootloader, os, kernel, etc) then it should work right?

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.

Flashing other variants?

Hey guys, I recently broke my s7e and got a check from Samsung to replace it. I'm looking for try cheapest way to do it and saw a deal on slickdeals with a comment that said:
The Sprint galaxy S7 edge can be flashed to be the 935U version, not sure about the non edge version. All S7 and S7e sold in the US have the same hardware though, so the Sprint version does already have the hardware for the 4x4 MIMO, flashing it to the U version if possible should be enough to put it on parity with the T-Mobile version on most things software wise (including Wi-fi calling I believe) and 100% on par hardware wise.
Yes just root, install custom recovery, download a tmobile rom that has built in aroma installer and you then own a unofficial ALL bands and services for tmobile s7
Is this at all true?

Well you could probably ODIN to different firmwares, but we have a locked bootloader and therefor no custom recovery. Could also try different ROMs on the exynos versions of the phone. But since they're different hardware versions I doubt you would get 100% functional software like wifi calling and VoLTE.

I thought that was the case. It was just really cheap and would be a great way to get another one if all I had to do was Odin the tmo firmware.

Yeah that would be a great idea. I know the phones are identical hardware wise. If I were you I'd do some more research to see if you could flash the sprint phone to tmobile through odin. I think it SHOULD work but having never tried I can't confirm.

I just flashed my Verizon 7 edge to the t mobile firmware and was able to use band 12, WiFi Calling and carrier aggregation. Should be the same for sprint.
Only thing I was told in the Verizon thread was that the firmware for t mobile is baseband 3 and the U firmware is baseband 2 so there is no going back until Verizon or U firmware is undated to baseband 3

I believe you mean the bootloader v2/v3... not baseband. Baseband is referring to modem.

The answer is NO you're asking firmware to replace/add hardware and that's not possible

I have a Verizon branded s7 edge and used Odin to load the 935U PI3 firmware. I am on T-Mo now and do have LTE band 12 working (validated with LTE Discovery). The research that I did found that the US variants have all the radios in them, but some carrier variants of firmware disable certain bands. By doing the 935U firmware, I also got rid of the notice on every reboot that I was using a non-Verizon SIM. So I now have all T-mo bands and no stupid SIM message.

I can vouch for same experience as SF-IT guy. I bought a G935V and flashed with G935U firmware via odin. Works on T-mobile, even wifi calling works. Currently on the latest PI3 version of G935U firmware. I would that you search the forum to see if you can flash the G935T firmware directly. The only downside of using G935U firmware is that the FM radio chip is not enabled in the firmware. I read that the all the carrier versions (September security patch and newer) of the G935 firmware have the FM radio chip enabled. I prefer the 935U version because it there is not carrier bloatware. Samsung bloatware is still there.

So what would the FM radio chip do? Just enable FM radios is all? Because if that's the downside then it's not a major setback as not too many people use the FM radio.

You definitely can. All US versions of the S7 & S7 Edge are the same hardware and can be flashed to any other US firmware. (including the U firmware that automatically works on all 4 carriers)

So what you're saying is that flashing the U version firmware will unlock by default all 930"X" and 935"X" phones? As in it just unlocks the mofo and debloats some while you're at it?
What's the catch? It seems too easy

Bloat is definitely gone on the U firmware, which is great. My phone runs faster and has more free space too.
I think some carrier features aren't supported on the U firmware. On T-mobile everything works (VoLTE and Wi-Fi Calling), but I think AT&T might have some issues with those.
If the phone is SIM locked to a particular carrier, I'm not sure that automatically gets turned off or not when you switch to the U firmware. You might need to contact your carrier first to get an unlock code?

What if I got a temporary unlock from t-mobile unlock app and then flashed this firmware? Would it make it permanent? Seems quite possible, but I don't know if the temporary unlock actually unlocks the phone or just inserts a bypass that would disappear if flashed.

I unlocked my US TMo phone when stock, rooted, and am running Echoe - which has a glitch where WiFi calling sort of works (can receive calls but not make them). In the TMo forum, there are threads on U - your comments here are more specific to what I am interested.
Which U firmware are you on and are you rooted (is is updated to latest v4 bootloader version), and did you have to ODIN and full wipe with CSC or did you get by with CSC Home to preserve data?
Also, are you on U CP or did you flash TMo CP to get all the bands?.

I Flashed 950U1/TMB Firmware on my T-Mobile Galaxy S8. Do I still have 4x4 MIMO etc?

While enjoying the bloat-free experience on the 950U1 firmware, do I still have 4x4 MIMO and other good stuff exclusive on the t-mobile software that the phone came with? Thanks!

Not trying to revive a dead thread, but I am curious if anyone can chime in on this subject? I have the SM-G955U1, but was wondering if 4x4 MIMO, 256QAM is all running, or is it best to flash T-Mobile firmware?

Just find the thread on.flashing csc or userdata

I used T-Mobile on my U1 S8 for awhile and everything seemed to work (Wi-Fi Calling, frequency bands, etc.). However, from what I’ve heard T-Mobile seems to be the only carrier that works this well with the unlocked S8 firmware. You might be better off to try the T-Mobile firmware though, as you wouldn’t have to wonder whether or not any capabilities were supported, and carrier devices have been getting OS updates quicker than the unlocked firmware devices.

I need help please I have the 950u1 on crf6 I want to flash tmobile firmware but it says fails please someone help me
