I have a SM-G930U. I wasn't expecting this to work...and it did flawlessly. Another surprise I got was flashing this firmware fixed my dm-verity issues. Thanks a lot for this thread. It gave a new life to a phone gathering dust on a shelf.

OEM unlock is an option in Developer Options. Has that always been there?
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
It's there but it doesn't work. It's just a toggle button that would come with most Android builds for the phones that actually have unlocked bootloader.

If there was root before (there is), then I'm pretty sure it will soon be available for Oreo too. I don't see why there wouldn't be unless those individuals who created or found the engineering kernel for MM AND N, aren't around to help out again. If not, back to 6.0 it goes.

HI, Now I'm on a custom rom with Nougat. Sim's carrier is Orange(UE). If I flash this Official Oreo version the phone will become Locked, right? Any idea how to unlock it, no charges? Thanks!

Thanks for the upload. I was trying to see if SamMobile had this up yet but they did not have it up when I checked. I have the MetroPCS variant and it did have 8.0 available on SamMobile already. I am switching from MetroPCS to T-Mobile so this will be perfect to get my phone 100% ready.
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
Personal opinion: Rooting is arbitrarily pointless now. Maybe fun years ago when devs offered new features or faster performance or UI changes. Most ROMs don't offer me any reason to root an s7. Most devs have moved on and just work on certain projects for the sake of the craft but all I've seen over the past few years as it pertains to customization and flexibility with root; I can now live without. My previous devices? Sure I NEEDED root. Customizing is fairly unnecessary and there's nothing a good app can't do to a phone these days. I haven't found one major benefit to NEED to root an s7. I have no real need to debloat or overclock an s7. Most mods and ROMs are basically the same as the official firmwares with tweaks I can live without. Lower-mid end devices that require debloat or a change in performance or if a person wants a different look are good reasons for rooting. Devs who like to mess around with stuff can also benefit from root. I just personally have no functional use for root anymore. iPhone also offers beta programs to test their new builds which is easier than keeping up with different mods, methods and ROMs and constantly having to reroot for almost zero noticable benefit. Rooting a decent Android nowadays is meh so I don't even keep up with root methods anymore to know if they exist.

I use SamFirm to download official Samsung firmware. You can auto search with your phone model # or you can manually search for all official firmware. Just download SamFirm. No reason to download from browser especially if they throttle the speed.

I'm not sure. My phone was originally a Verizon phone and then unlocked with 930U firmware. I've alternated between 7 and 8 carrier firmwares but I'm sticking with TMobile Oreo until Unlocked Oreo is out. I have a TMobile Sim so I'm not sure how each carrier firmware reacts to each carrier sim.

I have a G930T with the oficial stock 7.0, when I try to install this ROM, odin shows the green PASS message 26 seconds after I clicked start, then the device reboots and everything is the same... stock 7.0

What can I do?
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] DragonFire1024:
This is not recommended, but I had to erase nand. My S7 was originally T-Mobile. I couldn't find the stock firmware it came with to fix the DM issues. So I was on G930U before I flashed this firmware. Now I have no more DM issues.

Why can't you download 8 via ota?
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] DragonFire1024:
I wasn't able to either.
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
I'm wondering if that's because they roll out at different times in different areas, which is usually the case. I've seen people with the same phone as me and they get ota's before me or after me. Because if you are on official firmware and on the updated version, I don't see why the ota wouldn't come through.
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
Let us know if you were able to remedy the situation. The problem can't be the files themselves but the firmware you are currently on or if there is something preventing the update. In any case, there are certain firmwares you can flash first in order to get this to work such as atnt bra1 or 930u bra1 or the last 930u firmware which I believe is brd1

is it safe to downgrade ??
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] jsk560:
I had exactly the same problem. My phone model is SM-G935T which was unlocked from T-Mobile when running on build G935TUVS4BRC1 (Android 7.0). Now, I am no more with t-mobile SIM and put in other carrier SIM (Airtel India). But it is not working when I update to the new OTA update G930TUVU4CRF1 (Android 8.0). Not sure whether it is looking for an unlocked firmware or something. I just did OTA and installed the update and found that it is throwing "mobile not registered error". I had to flash G935TUVS4BRC1 (Android 7.0) again to make it work.

Now the phone is running on 7.0 and I doubt whether I can do OTA update. Does a downloaded firmware from sammobile would work instead of doing OTA?

[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
Yea there's no problem downgrading between 6, 7, and 8 as long as they are official firmwares. The s7 has had all three Android's on it. Just don't try to download certain ROMs unless you've followed the instructions of that rom because you don't wanna try to flash something on a phone with locked bootloader because it won't go through.

But you can safely alternate between Android 6, 7, and 8 on the s7
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
Yea sammobile and/or SamFirm will have the correct official files. Not sure if this has anything to do with it but make sure that you are using the firmware for the s7 EDGE which is 935.. 930 is the s7 flat. Currently the g935t is on G935TUVU4CRF1. SamFirm gives you all the files you need to flash in Odin to get back to official firmware. Also try to Google how to get Airtel India Sims to work on unlocked devices because I'm not sure how our unlocked phones interact with certain firmwares and certain sims. I've just always used my TMobile sim in all of my Android phones since 2006

Switching from verizon to T-mobile

Will this file fix my issue? Switching from versizon to t-mobile with galaxy s7. When I put t-mobile sim in phone states "SIM card is not from Verizon wireless" (phone according to everyone at Verizon is unlocked). Contacted both Verizon tech help and tmobile and neither was able to get a fix despite talking to one another (tmobile lady said verizon should be able to "white wipe" ?? the phone to allow its use on tmobile) Sorry I am no expert on these things and was hoping if I was able to swap the verizon firmware for tmobile firmware it my recognize my new SIM. Guy at the tmobile store was able to set the APN and get it to work for about 30 min until I went into a dead zone and then wasn't able to regain tmobile network again after that point. I am sometimes able to text but no data or calling since that 30 min split. Any help would be greatly appreciated.
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
A fresh flash of this and then a factory reset n cache wipe may fix it. If not, it may also be the areas with bad signal which you would have to contact TMobile for a fix, like you said with them updating your apn settings. Other than that you could also have a faulty device or something like that.

I have a SM-G930T PDA G930TUVS4BQL2 which I bought carrier unlocked to use internationally.

If I upgrade to Oreo 8.0, will it lock me to T-Mobile? or will I still be able to put in any SIM to use in any country?

Hi there and thank you in advance for your contribution here.

i have download 3 times the firmware but each time winrar says files are corrupted ?

any idea ?

Thank you again
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
You shouldn't need WinRAR for anything when flashing firmware. You are downloading the zip and then simply extracting the files into a folder. Then you are using Odin and putting the files in their respective places.

Have you tried factory resetting and deleting caches through recovery to fix the bootloop?
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] nk1960:
Thanks for the fast reply

Maybe i was not clear in my description.

i download the zip file with the firmware but while in the unzipping process it I'm getting the error message that file is corrupted.

and to answer your question . Phone its stuck in a boot loop mode that cannot go any further than the first step in recovery mode (blue letters top left screen. ) wont even go to the recovery mode menu to give me the other options BUT will go to download mode ONLY when its plugged in the charger. If i unplug it turns off immediately. I had to order a Y cable to simultaneously take power from charger and data from pc. I'm going to try to flash it right now and I'll post results for any other members that had the same issue.

Again thank you for replying and hope firmware will not having any corrupted file.
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
Files aren't corrupt. They are directly from Samsung servers and I redownloaded the files myself before I replied to your first message. Hope everything works out :)

Update 08/06/18

I downloaded zip and even used WinRAR to extract files and they were extracted without issue. You may want to turn off your antivirus or check your version of winrar. If you are on windows 10, you don't even need WinRAR to extract files. You simply right click the zip and click Extract All... Which should be above pin to start and below open in new window.

im looking to get the 930U (from best buy) to use with my metro pcs SIM card, if i put this t-mobile firmware on my phone, will my SIM card still work on the phone since the phone is already unlocked?

im not sure if the bootloader is lock on the 930U? is it hard to unlock that?

is there a step by step guide to load this t-mobile software?

EDIT: forgot to ask if i can use VoLTE/wi-fi calling with the t-mobile software with my metro pcs SIM?
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
Locked bootloader just means it can't be traditionally rooted and flash certain ROMs. You're fine to alternate official Android firmwares. I use TMobile sim card on unlocked firmware since it doesn't have carrrier bloat ware. You could use TMobile or unlocked firmware with metro, I'm not sure about volte or wifi calling. I only got wifi calling working when I was on TMobile firmware with my TMobile sim card and I also had to call TMobile for them to refresh all my information attached to my imei number with updated phone number and all that stuff so I'm not sure about wifi calling because I had to call TMobile just to get them to get it working again. But I can verify that wifi calling is working for my TMobile sim on the 930u Oreo firmware
[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] phoneguy412:
ok so the unlocked firmware thats already on the 930U will stay unlocked even tho the phone was flashed with tmobile firmware? so i can use any SIM card

are u using the phone now on tmobile? if so are ur calls using VoLTE?

i think the tmobile firmware is needed for VoLTE and wifi calling to work on metro pcs/tmobile

how easy is it to flash the tmobile firmware?....i know computers just not sure about this.

thanks for the reply

EDIT: this is the right 930U?

[T-Mobile Samsung Galaxy S7 Guides, News, & Discuss] aarongotgame:
Reflash. I'm not sure what you're doing wrong. This is for the s7 snapdragon varient and all you should be doing is turning on USB debugging mode and putting your phone into download mode, plugging it up to your computer and then putting the files in their correct places in Odin. After it restarts you go into recovery and wipe the caches n do a factory reset if u want to be sure everything is clear n working fine. I've been flashing my s7 from Verizon firmware to atnt firmware to TMobile firmware and unlocked firmware, from Oreo to nougat and back to Oreo with zero problems. So it's hard for me to help people without understanding what the problem could possibly be. Flashing with Odin isn't hard so I don't know how some people are having this much trouble. I've even reflashed both my uploads (TMobile Oreo and unlocked Oreo) and I haven't had any issues with the files.

For those of you still wondering, I started with the AT&T (Darth Cookie) beta firmware for SE9, and only switched to the T-Mobile official firmware when it became available - all without changing either SIM or carrier (T-Mobile SIM/Tracfone carrier). Now I am getting ready to update the firmware to the June 25 (latest available) firmware (still T-Mobile). The only thing I am doing beforehand is making sure the phone is properly backed up and fully charged; that is, indeed, literally all that should need to be done.

You flash all files n choose between the csc or home csc. Home csc is supposed to be for when people don't want to factory reset the phone n keep some data or something.

Latest Firmware Search Method (SamFirm)

If you want the latest firmware (and are using SamFirm 0.3.6), you can use the automatic method to dig it out if the carrier code is known - for example, for the S7 flat on T-Mobile, this is G930T with a three-letter (country) code of TMB. (This same firmware can be used for MVNOs on T-Mobile's network - such as Tracfone - it is not just for T-Mobile direct or Metro.)

1. Does this method apply to all carriers? Yes - as long as the carrier has a specific firmware for the phone. (For MVNOs, you can use the network 's firmware if you don't know the information specific for your carrier; this is why I use T-Mobile's firmware - I don't have the same information for Tracfone itself. If I were using the Verizon Wireless half of Tracfone, the same information I posted above would be G930V and VZW, respectively.

2. Does it matter if the phone itself is *branded*? Absolutely not! My own S7 was Verizon Wireless-branded on the phone itself - and still is.

3. What "gotchas" are there with the current firmware? There is one "gotcha"; unfortunately, it's an ugly one - the b8 firmware series (regardless of carrier - even the G93xU (carrierless/unlocked) firmware is affected) blocks downgrades AND crossgrades - even to other official firmware - only OTA upgrades are permitted. (Therefore *ugly*.)

Did you try flashing with odin after enabling usb debugging. Just double checking. What do you mean it's not letting you update. Odin either fails or succeeds to flash files. It doesn't say whether the phone is on it's current update or not. If it's a 930t then it should have no problem with these files.

930p firmware is Sprint

I tried also to update it from PC with Samsung smart switch without any success. And i did try using odin with firmware files from sammobile.

Here are the questions:

1. Why am i blocked to updates?

2. Is there any way to update this phone manually? what is the easiest way?

3. Do I have to root the device in order to update the android version?

4. Can I update it directly to the last android version available (8.0.0)? or do i have to to it by steps?
