Possible to convert flash SM-G930U firmware on a SM-930P?

Hey guys!
Yesterday I got a Sprint carried S7 SM-930P as a gift. The only problem is that although it works flawlessly on my sim cards (I'm not in the US), I found out that the 930P won't get the 7.0 update. Is it possible to flash the G930U firmware without messing my phone up?

I wouldn't do it unless your absolutely sure, I wouldn't be so sure if it's for a different model number. If they were able to have the same firmware flashed Samsung would just release it, they obviously didn't because it requires extra effort, pointing towards the conclusion that the firmware is not flashable on 930P

You can flash it, i have done it myself. There are many guides over here that tell you how. All S7s in the USA are the same exact thing hardware wise, only the software (firmware) is different. Am currently running SM-G930U firmware on an SM-G930VL S7. @op the sprint s7 (SM-G930P) already has android 7 as of last 3 weeks

Hi Guys. I just wanted to make sure i can do this to. Since i have the sprint version which I've already unlock. I don't mind the few bloatwares. But my issue is i can only hotspot to one device with my S7
If i flash a 930U firmware. Do you think it will solve my issue ?thanks in advance.. yeah btw since I'm not in the usa, So im not using sprint. I can't change that hotspot plan. If i want to make more devices connect..

SM-G930P converted to SM-G930U
Hey guys. I was able to flash the sm-g930u firmware downloaded from sammobile... the problem I have now.. I have a blank csc. No product code.. and on software updates it fails to register my device. Also in settings . I have some weird options. Which some of them are repeated. I will upload screenshots.. Also there's a system UPDATE option and also software option. Which one of them fails to register and the other only works with Wi-Fi. Should I revert back to my stock sprint firmware. If so do I need to wait for a firmware with same build date or newer. Because on sammobile haven't uploaded a firmware with a build date on par with the current install. Then I would have to wait right. ? If using a older firmware it will brick or do something to my phone ?​

Did you flash all file in the SM-G930U folder (AP,BL,CSC,CP)? Because i did it with T-mobile,Verzion an it work fine

Thanks for the reply. Already solve.. what happen i flash home_csc. So ir was like that. But then i made a back up.. and flash again using the csc file. And all work perfect. At first phone was with the SPT csc.. then after i restored phone and pop in my sim it did something.. and now I'm with XAA csc. Works perfect. And could receive updates (phone registered). Just waiting for the july security patch update. Btw phone works better in every way.. battery even last longer..

Hey Buddy. I would recommend doing a full back up on your phone., using Smart Switch app
It saves all your numbers, message, etc..
Then proceed to flash the latest firmware for the Region or Provider. Using (CSC) not (home_csc) which means flashing the csc will wipe your phone data. Phone will be like new again. Proceed tru set up. Loggin in gmail. Proceed to update smart switch app if not found in apps. Then restore from the back up file. And good to go.

actually all S7 are not the same hardware fyi. The Sm-g930p has chipsets snapdragon and uses cpu procesaor quad core but the sm-g930F has the chipset Exynos8 cpu is octa-CORE the chipsets vary from these two. Flashing firmware for one chipset to the other may cause major problems bot to mention bootloops.. but I looked up sm-g930U and it uses the same processor as the P model.snapdragon

He said all S7's in the USA are the same, which is correct. Exynos/930F isn't sold in the US, only way to get one is to grey import.
You can flash any USA model's firmware onto any other USA model because they're all the same hardware.

anyone running the 930p with current update how did you get around the binary 6 lock all the 930U firmware versions I can find are binary 4 I think t-mobile is 5. Anyone got links to a firmware we can push to sprint variants that are binary 6.

You can't get around it. It is currently impossible to "downgrade" the bootloader binary version. All US carrier variants are version 4, except Sprint that is 6. You are stuck.
The only way it would ever be possible is if (a) one of the carriers, in a future software update, increases their bootloader version to 6, or (b) if someone figures out how to unlock the bootloader for the Snapdragon models.
Neither of those options is likely to happen, ever. You might get lucky and hope the G930U unlocked version has a higher number (it hasn't been released for Oreo yet), but I wouldn't bet on it.

Blame Sprint; there is really no reason for them to do what they did except keep users from switching their phone to another carrier. This isn't a Samsung thing. I don't believe you would be able to do this with any other Android phone, either (i.e. go backwards in bootloader versions).

Convert SM-G930T to SM-G930A so I can use AT&T LTE bands.

Hi All, I want to continue using my AT&T prepaid plan but I recently bought a locked T-Mobile Galaxy S7 SM-G930T (I'm going to try to unlock it - if that doesn't work this is all moot). I would like to flash AT&T firmware so I can use the AT&T LTE bands. Can I follow the instructions in the link below once I've unlocked a T-Mobile SM-G930T and turn it into a SM-G930A?
http://www.droidviews.com/nougat-firmware-on-att-galaxy-s7s7-edge-sm-g930a-g935a/
I've read the link below... but it seems to be only if you want to continue using T-Mobile service which I don't.
https://forum.xda-developers.com/tm...w-to-flash-att-nougat-to-t-mobile-s7-t3553610

Changing firmware doesn't have anything to do with what bands the hardware supports. Unlock it and throw the ATT SIM in. Only difference is carrier supported features and software (wifi calling, etc). Flashing ATT modem might improve coverage but all S7 support the same bands.

Thanks buddy for the reply. I'm used to using a custom ROM on my Android phones so this is new. Mostly CyanogenMod.
That's good to know I don't need to flash in order to get the bands but I understand I need to if I want OTA updates from at&t. It seems relatively simple that you just flash the AT&T ROM over the T-Mobile with Odin and then use some update file. It doesn't even effect Samsung pay and Knox which is great.
Stupid question: is the AT&T modem included with the AT&T rom? Also, with regards to the 2nd link in the OP what is the update file that you put on the sdcard to use in recovery - is that an OTA update because your ROM is different from your carrier?

The following is the latest G930A Android 7.0 firmware file. All you need to do is flash it with Odin's AP slot to completely convert your G930T to a G930A. No other steps or files are required: G930AUCS4BQC2_CL10280464_QB12904132_REV02_user_low_ship_MULTI_CERT_meta.tar.rar

I don't get why you would do this other than to have ATT bloat over TMO bloat (IMHO TMO has less bloat than ATT). There's no technical advantage. Am I missing something?

The amount of bloatware is irrelevant since you can freeze all bloatware on either build. I experienced many issues on the TMo version including issues with Android Auto, Google Assistant, and Tasker. I thought these apps were buggy but all of those issues were resolved on the AT&T version. The AT&T version seems to be a better, bug-free build.

Read that in a different thread you posted to after I responded. I think it's very YMMV though. But if you saw improvement then ??

Hi, did anyone ever complete this flash from SM-G930T to SM-G930A? I'd like to do this solely to try and get the wifi calling feature since my workplace has poor cell service but great wifi. I bought the T-Mobile phone, unlocked it, put the ATT sim in and everything but wifi calling works fine. I appreciate the reply!

This is much later in the year (11-8-2021) and ATT has posted the list of phone they say will work and it only shows G930A. It seems their test of working means it must have been sold by ATT. They say My G930T won't work. So Will ATT continue to use customer's unlocked phones it they were not orginally sold by ATT. They have the records. Will ATT refuse to use one of their SIMs even if the phone is Flashed to ATT logo. I do not want to throw away my G930T phone.

Hello and thank you. You posted this information and link back in 2017 and so much has changed. Mostly ATT is now working hard to get rid of all 3G towers and firing up 5G. They said my Galaxy S7-GM930T would not work so I think they link you posted will help me convert the phone back to a GM930A or U or U1. My question is,..Has anything in your post changed since 2017 and if so could you please advise me of what I need to do. Thanks very much.

If I flash unbranded FW on a carrier specific device, loke tmo or att for example, would it sim unlock the phone?
If I flash tmo FW on an att s8 would it in turn allow me to use the att original device on tmo? I ask these questions because I feel like it would work for both my questions since flashing the FW flashes both boot, kernel and baseband/radio. The which is needed for signal. Just some theories but would love to know the answers.
Btw, I have a F model S8+ and was planning on buying some US branded devices so I was curious.

No, it will not unlock the phone (Note: Verizon phones are factory unlocked and remain that way after a firmware flash)
Yes, you can flash any carriers FW to a US S8 and use it with a different carrier.

So I understand, your saying if I flash att FW to a T-Mobile s8 I can use it on tmobile? If that is the case, to me that's an unlock of sorts tiny book lol. Just wanna make sure is all

Just realized the typo.....what I meant was, if I flash ATT on a TMO variant I can use ATT while locked to tmo? I'm very unfimiar with combination fw and always opted for the UK models for alot of reasons. Sorry for the confusion of my op question. I know on the s7 and edge if you flashed the US unlocked firmware it not only removed AOL bloat but it unlocked the device. So that is why I ask.

I had a TMobile S7 edge and flashing unlocked firmware never unlocked the device. That's handled by TMobile servers so...
Flashing unlocked firmware will give you just that. The smoother, bloat free firmware from another device but not the actual sim unlock.

I bought an unlocked device and wanted wifi calling so I flashed the g950usqs1aqf7 att firmware with Odin and it worked to enable wifi calling but I'm unable to get any ota updates and I hate the bloat. Is it possible to get WiFi calling with an unlocked firmware like this one? Also what is the difference between the U and U1 firmware variants?

There are plenty of threads on this, but I don't think anyone was ever successful. I flashed att Oreo to my u1 and got the options, but can't get my company to change my imei back.... My personal phone sim works fine. Quit at that point since it's an Ims registration error. You can try merging the wifi calling apks, but I'm pretty sure it's baked pretty deep in the os. The Verizon guys got some of it working. You can try their threads and see if any of it applies to us.

Thanks. Some threads made it sound possible but inconclusive. I'll just assume it doesn't work.
BTW, can you link to the att oreo fw? And what do u flash that with Odin or comsey?

The thread right below this one entitled Oreo ota has all the details and it needs to be side loaded through adb. Not Odin. But you will need to Odin the 950u base to get off u1

Ok thanks. I need to flash anyways because I'm having terrible battery issues and just debating whether to go to a newer version of 950u or back to U1 and losing WiFi calling. In your opinion is oreo beta worth it

So just to confirm, I have read everything, but I am just a bit confused. If I flashed the unlocked firmware via modified odin on a locked AT&T S8 it will remove a lot of the carrier bloat and give my my wifi hotspot back, but remove wifi calling. Similar to when I flashed the T-Mobile firmware on my AT&T S7 and got rid of a ton of the AT&T bloatware but was able to activate my wifi hotspot but lost wifi calling. I stay locked to AT&T which is fine that is not my purpose for flashing

The links don't work. Any chance you've still got the firmware? I've been overseas since october. I have an unlocked AT&T phone that I intend to keep using when I get back, so I want to keep it AT&T FW.

Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?

What is the difference between the G955U and the G955U1?

I have a G955U1, is this ANY different than the G955U? Besides the name, I mean. Can I flash G955U firmware on my G955U1? Thanks.

Simply put. There is no bloat. You'll get all the features samsung intended on their phones. You won't get features from carrier phones.

but in G955U1 the bootloader is locked

I have been asking a lot about this myself. i am on tmobile. not sure if i want to make the leap to unlocked. want to keep visual voicemail, wifi calling, rcs support and what not. but i want to get in on the beta for pie. running drl7 now but the video bug with netflix and what not is annoying.

The u1 is bootloader locked. The u firmware is bootloader locked
If you own a u device and it is not sim unlocked the only advantage u1 firmware give is carrier bloat.
The u1 firmware can be flashed on a u device. But other than listed above no other perks come from this.

If you own a u device and it is not sim unlocked the only advantage u1 firmware give is carrier bloat.
The u1 firmware can be flashed on a u device. But other than listed above no other perks come from this.

I can semi-confirm this. From the recovery menu I can select bootloader and it boots to SOMETHING.....but it looks like it's booting to their downloader version and not what people would traditionally see from a normal bootloader screen. I do know this screen does NOT work for having the phone detected by Platform Tools so no way to use that at all as far as I can see. UGH. I swear I should have just bought a Pixel 2 when I had the chance. GODS Samsung is annoying. :crying:

When you click reboot to bootloader it takes you to what as known as download mode which is how we flash stock firmware. And maybe a couple other things but yea mainly for stock firms. Its used by a program called odin and the latest is 3.13 i believe.

Yea hopefully someone will respond to my main question in the noobie thread. Or maybe you would know. So I know Odin is the program Samsung uses to load new ROM on a phone. And I thought I read somewhere that there was a modified version of Odin that someone made that could install new/different ROM's. But I also saw in another message that either the current version of Odin, or the current version of the modified Odin could still load other ROM's and that someone had tested this. So that was my original primary question.
Is there a way I can use one or the other to load a Stock Android Pie ROM like what might come with a Pixel so I can avoid all the garbageware from Samsung? Or is there a chance doing that, that I would have some of my hardware features disabled since that seems to be an issue loading a ROM from another phone? And if so. Has anyone made a ROM for Samsung phones with all the garbage programs removed? Or is it still too early in the release of Pie for Samsung for that to be a reality right now?
Thank You for the info.

There is a pie beta I don't know if it is official yet. If you flash the unlocked firmware I've read you lose features like WiFi calling and volte. But I have not tried pie or unlocked firm ware on mine. There is a thread on installing safestrap then doing a rooted system images then from there depending on the flashed image if you do debloat. Again I haven't tried the new root method. I'm still on a really old revision from end of 2017

Ok thanks for the info. So apparently right now it's just a bit too early to be trying to find a Pie ROM that would work with my phone and not loose some hardware features. Which I guess makes sense since Samsung is only just now releasing it for S9's I believe in european countries I guess primarily to make sure how they borked it with their own software and tweaking didn't totally screw up their phones. Heh.
Oddly enough I got all excited when I saw it said there was an update today, but all it was for was a security update to bring it up to "Feb 1st, 2019" Android security level.
Thanks for the info about things. :good:

Yes you can flash the u1 firm Ware as long as its the same revision bootloader 5th digit from the last.
I think you have to flash the equal combination file first

Sprint S8 Active flash to T-Mobile?

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.

I AM NOT THE CREATOR NOR DO I TAKE CREDIT FOR THIS

No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?

Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?

I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint

Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487

Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.

So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

After flashing Sprint variant of the device to T-Mobile firmware, do all features work: WiFi Calling, Band 12, VoLTE and Band 71?

No wifi calling, no VoLTE. Not sure about the bands

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.

flash not working?
i flashed the tmobile firmware and after its all dont i boots up does an update and then boots with all the sprint stuff still

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".
