I need advice - Samsung Galaxy S8+ Questions & Answers

So, this has probably been answered before, but I am honestly too busy (also lazy due to the extreme workload of my professional life) to search through thousands of threads for the answer to my issue.
I got a SM-G955U that was originally used on the sprint network from a guy on Craigslist (Mistake number 1). I immediately performed the carrier switch tasks to change it to a SM-G955U1. The firmware change was easy as pie, and the device runs smooth as butter right now. The issue I ran into is that it is telling me that I have to contact sprint to unlock the device. I am sitting here going, "Wait, what?"
So, I may have overlooked some details when I flashed the firmware. I am going to try reinstalling the firmware for XAA without using the Home_CSC file while I wait on replies to see if I can solve this issue with some tinkering. I am extremely tech savvy and I ha e been rooting devices and changing firmware files for a long time now, and I have been involved in a lot of development projects.
Anyway, my question is this: How do I go about removing the Sprint OMADM protocols. I assumed that flashing the firmware to the XAA firmware would have handled that, and as I said before, I either overlooked something simple when I flashed it over the first time, or there is something I missed all together.
I cant really go to Sprint about it since I am not a Sprint subscriber, and I dont know who to co tact at Sprint about this. Also, if the guy I got it from defaulted on his bill, then the device is probably black listed by them and they wouldn't unlock it for me anyway. Yeah, I know, this is stuff I should have looked into before I bought this damn thing (Mistake #2).
These are the details of the device just in case somebody has a solution:
S/N: R28J42MCXBT
IMEI:Removed for your saftey by @TheMadScientist
Brand: SPRINT (I don't know why considering I flashed the SM-G955U1 XAA firmware to it, and the SIM was not installed during this process).

More than likely a paid unlock service as the device is carrier locked and no feasible methods really that I know of....

That's what I was afraid of. I figured it would end up being something like that. You would think there would be a way to accomplish it simply with some reprogramming.

You know, I might have an idea...its risky, but if I refreshed the XAA firmware with Prince Comsey's Odin and performed a Nand Erase, could that potentially wipe out all of Sprint's programming? Or would that wipe out the factory recovery and brick the device? I know it is an overkill solution, but if it's possible for that method to work then I may have a go at it. I just figure that there HAS to be a way to wipe literally everything from the device and start with a new install from scratch.

Prob not. On older lgs models we used to get into the lot hidden menu and switch it to lab mode. But I'm pretty sure sprint blocked all the good stuff

Ahhh yes, the good old days. I remember the days of being able to simply root a device and having multi carrier functionality. More than that, I remember how easy it used to be to root and install custom bootloaders.
Coincidentally, I always thought it would be awesome to run some variant of CyanogenMod OSs on devices like the GS8+.
Well, theoretically, could I just root the Sprint S8+ on the unlocked firmware and just modify the build.prop file to ignore all things sprint?

the unlocked firm should be free of any sprint stuff...If its not than the 3 part csc isnt setup right
XAX/XAX/XAX or xaa or something like that
if device code shows a spr anywhere then its still trying to default to sprin software

Okay. So it looks like I missed something. When I flashed it initially, I was on severe lack of sleep due to being severely understaffed at work (we still are, and I have been pulling doubles for over a month now), and I bet I used the Home_CSC instead of using a clean CSC file.
So, to correct this, I will have to flash the ENGboot again, then flash the XAA firmware over to the device again, and set up Comsey's Odin for a clean install instead of copying and applying Home_CSC. Is this correct? Or, because I already have the "unlocked" firmware, I should be able to just do a clean flash of the stock G955U1 software? I just wanna make sure I dont wipe and repeat what I did the first time.

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..

i'm from morocco and my phone is also unlocked to use my service provider SIM card ( maroc telecom) but I'm stuck at marshmallow 6.0.1
and I need to flash the U firmware to get rid of bloats and get OTAs but i don't want to screw something.
please can you make it clear what CSC to flash with ? and how so ? I mean like Screenshots.

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).

I bumped into a locked firmware and I don't know what to do

Hi guys. This is my very first post here. I searched all over the internet for my problem but nothing. But it seemed that similar questions redirected me to this forum and that's why I decided to join.
So, all started this morning, when the colors of my Galaxy S7 Edge became faded, it was more noticeable on the black color. I tried to find a solution online and they suggested doing something under Developer Tools. The next problem and my big big mistake, was that I unchecked and rechecked something, that after restarting my phone, wouldn't let me enter, showing a text "Custom binary blocked by FRP Lock". I searched for a solution and I saw that the only way was to install a new firmware.
I always thought my phone was SM-G935FD, because that is what it read on the "About device", but at the download screen it showed SM-G935W8. So I downloaded a firmware for the SM-G935W8. This is what it says also on the back of my phone, i noticed it just some minutes ago. So I went and I searched for W8 firmwares. I got the 6.0.1 from Canada and Bell carrier if I am not mistaken. I did the instalĺ. It started well, but after some updates it went from 6, to android 7 and it blocked my actual carrier. I can't make any phone calls.
Now I don't know what to do. I live in Albania and I purchased the phone here, it was a used one. I think at some point the phone was rooted because I had some very strange apps that has to do with rooting apparently (I never rooted a phone and I don't know much).
I want to know if there is a way to have an unlocked firmware. I don't even know what carrier was the phone on the first place.

Try flashing the SM G935FD, it probably had the G935FD firmware flashed on it so that it would work in your region, flashing G935FD again might make it work again.

Okay but, which version of FD? Because I search it and I see versions for countries like Vietnam, Thailand, Nigeria etc etc, and I am not sure if it will be a locked version again.

If it was rooted before, it was probably rooted so that some things could be modified to make it work in your country.
You said you flashed an android 6 firmware then you did an OTA update to android 7. That might be a problem because it might not be able to root again in order to make the modifications that were originally done to make it work in your country.
Here is a link to all the Russian firmware for SM G935FD, try the 6.0 firmware, try the various 6.0 firmwares and see if any of them work. After flashing the 6.0 firmware, if you get a notification saying there is an update available, DO NOT ACCEPT IT, keep the 6.0 android version. You will probably still be blocked by FRP, according to XDA rules, we can't help you bypass FRP, you'll have to figure that out yourself.
https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935FD/SER/
Once you get FRP straightened out, do some searches for:
"How to root SM G935FD"
Then you can work on getting it configured to work in your region on your carrier. Sometimes this involves flashing a separate modem(radio) file that has been extracted from a different firmware in order to make your radio work with your specific carrier. You might be in for more than you bargained for. I don't know which specific modifications you'll need or what files you'll need to make it work in your region, im just trying to give you an idea of what you need to look into.
You can try some of the Russian android forums, someone there might know how to make the device work in Albania. You might want to ask around in those forums first before you try anything, that way you won't waste time trying things that might not work. It will save you time if they know where you need to start and what you need.

Updating problematic device from Android 6 to 8

Hello,
I bought an S7 from eBay, it was marked as a "new" and "UK" phone. I factory reset the device on receipt and apparently worked fine to start with. However, there have been a few problems (poor signal, battery life, echoes in video calls) and I noticed the device was still on Android 6, so wondered if an update to Android 8 might help (?).
There is no menu option available to update Android so I started looking into flashing firmware. On further digging, the device seemed an official SM-G930F but "United Arab Emirates" appears in the "About Phone" section.
I downloaded some stock firmware (Android 8, UK Vodafone which is the network I expect to run it on) and tried flashing with Odin 3.13 and it failed with error "unsupport dev_type" on the phone screen. Any suggestions?
I also noticed that in "Download mode" the phone said it was a "SM-G930V". I wondered if this was why the flash had failed. For the SM-G930V I only seem to be able to get USA/Verizon stock firmware. Might this work or would I have trouble using this in the UK?
Any help would be much appreciated. I'm a newbie in this area so apologies if any of these questions are answered elsewhere.
Many thanks,
Edwin

Go to the play store and install Sam phone info, then look at what chipset it lists, you don't want it to be Qualcomm Snapdragon, Eyxnos is what you want to see.
G930V is US Verizon firmware
Report back please.

Thanks for your reply! The "hardware/board" is "qcom/msm8996". Where does that leave me?
I noticed that the Bootloader & Baseband Versions begin G930VVRU but the PDA and CSC versions begin G930FXXU. Not sure if that means anything.

Well the person who sold it to you is a liar for starters, it's not a "brand new UK device", it's a US S7 (G930V) Originally bought for the Verizon Network in the states. They are difficult to do anything with as the Qualcomm boot loader is locked down.
So your first option is to update the firmware to the latest Verizon Oreo, probably not worth it since that firmware is designed to work on a couple of frequencies only.
Next option is to flash unbranded US firmware with a modified version of Odin that ignores mismatch devices etc and just installs the firmware. You will need to use this version of Odin from this thread >>> here Odin 13 PatchD.zip is the one you want.
Unzip, run Odin, place phone into download mode flash firmware. You will need to download G930U from Sammobile or undato.com The 3 letter code should either be USC or XAA.
Any questions please ask.
Also before flashing please remove you google account off the phone.

Next option is to flash unbranded US firmware with a modified version of Odin that ignores mismatch devices etc and just installs the firmware. You will need to use this version of Odin from this thread >>> here Odin 13 PatchD.zip is the one you want.
Unzip, run Odin, place phone into download mode flash firmware. You will need to download G930U from Sammobile or undato.com The 3 letter code should either be USC or XAA.
Any questions please ask.
Also before flashing please remove you google account off the phone.

Thank you for these detailed instructions -- much appreciated!
Presumably using this version of Odin carries a high risk of bricking the phone if I get anything wrong?
Out of interest, what's the reason for removing the Google account?
Cheers,
Edwin

Because it's a further complication with FRP lock you just don't need after flashing. Just add the google account after flashing and your good to go.
With regards to flashing yes there's always a risk that something can go wrong, that's why you take your time and follow the steps exactly. In your case it's pretty straight forward and remember nothing changes on the external SD card, so anything you want to keep can be moved there before flash.
I would also mention that theoretically you could flash UK unbranded (BTU) but it's for G930F Exynos devices so best at this stage just get the device on unbranded Qualcomm and working on UK networks.
let me know how it goes.

Hello,
I've just tried doing what you suggested (I think!) and I got a failure. Odin said "FAIL! (Auth)" and the phone said "Secure check fail: apnhlos". I tried rebooting and got a security error. So I tried Odin again and it passed.
However, now the phone won't boot, it alternates between "Samsung Galaxy S7" and a blank screen. In recovery I get:
"#fail to open recovery_cause(No such file or directory)#"
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3
dm-verity verification failed..."
Any ideas?
Thanks a lot,
Edwin

Ok, so try an earlier G930V firmware and please make sure you are placing the file in the right places with Odin. The US carriers have all updated their firmware and often closes the loophole which allows the patched Odin to work. Then it's just a question of waiting until someone develops a workaround again.
Also you can pick up an S7 from ebay for about £100 now, your always going to have problems with a qualcomm device on UK networks. Where about are you in the UK?

Thanks! Actually shortly after posting I found a suggesting of using CSC not HOME_CSC, which enabled the flash to work (at the expense of phone data, as expected).
The device still does have a few issues though, as you predicted. Is the radio hardware different for Qualcomm? Might need to buy another then. Any advice to avoid being scammed on eBay again?!
Thanks so much!

Well you could flash G930U which opens up all of the radios for the US and you may have less issues but US and European devices have different chips so your never going to be able to flash any EU generic firmware. I'm addition the US and Europe are different cellular regions with different operating frequencies. You can get by with what you have but never get full functionality.
I think you were just unlucky with this phone on ebay, there are plenty which are genuine EU region devices.

Running RETUS on a MetroPCS Ocean device

Last night as part of rooting, I was getting issues with the MetroPCS Ocean firmware with the update failing message. I took a look at the RETUS firmwares and saw the latest so I took a chance and was able to flash the Retail version with no problems, booted up and 'worked out of the box' so to speak. It is also lighter on the features since it doesn't include the MetroPCS apps. I am not going to try rooting with this one, but it seems to be quite stable and an a little faster if that makes any sense.
Your mileage may vary!
You assume any risk by attempting the same thing on your device, but I figured it would be something someone would be interested in knowing.
I'm running MetroPCS software on a Amazon device
I'm running Cricket software on a MetroPCS device &
I'm running Amazon software on a MetroPCS device
Cons on both I've come across so far.
Cricket software on a MetroPCS device I get Boot screen says Bad key in top left corner before loading the device.
Amazon software on a MetroPCS device I get a Boot screen says untrusted device before loading the device.
Pros is they both work great.

Since you did that when you have the time, try to go back a lower build or your OG Build and check if you still have data and sim accses. I ask because (I have a RETUS) and since I flashed the latest one available "PPO29.114-108 May 1 Security Update" can't go back to OG Build it came with without losing data and sim detection. Something was updated in that build that even if you flash back it broke that. I even flashed the modem to check but no still no data or SIM detected at all. Only all fine in the most recent build.

Flashing a Carrier or Retail ROM won't ever unlock a Carrier Lock device. If it were that simple don't you think we will ever have this issue. Hell the term network lock won't even exist in a perfect world.

And yes there are several Motorola Devices that are firmware interchangeable. Been doing it since the first Moto X times. Only benefit from this procedure no bloatware and faster updates that's it. Oh and better performance since it doesn't include crappware

PSA. If you flsh Cricket, Metro etc Roth the RETUS Latest firmware you won't be able to go back to you LG firmware. That firmware updates the Bootloader and that preventa going back to a lower workifn version. You can doing what I posted earlier by while flashing back to OG Firmware skip flashing modem and fsg bins and don't execute the modem erase commands.

Ok I bricked my phone via magisk update, I was on MetroPCS variant of Ocean firmware. Now I manually flashed RETUS PPO 29.114-108; It seems to be running fine other than saying my device is not certified....is there a custom recovery that will work for Ocean RETUS using twrp? Should I try to re root using magisk systemless-ly copying boot.img? Thanks for info and any input would be greatly appreciated! Thanks

Can we get directions on how you guys are doing this please. I've tried using the back to stock directions but extracting a different firmware but it's not working. I have Metropcs.....I extracted Tmobile firmware and use the back to stock commands...but when rebooting its' still Metropcs....please help with some directions.

I'd like to know as well, I got 2 of these Moto G Power 7's from Metro PCS and would love a stock ROM without all the metro bloat. Not sure on Metro's unlocking policy if they will unlock it and what bands this all has if it has CDMA or is it GSM only?

If I were you I will stay away from Magisk until they update the app, still damaging the boot.img files..

Instructions are in the thread back to stock.
Secondly, I'm on MetroPCS and flashed the retus2 firmware (BestBuy versions) no MetroPCS bloatware. Flash the retus2 and you'll be fine.

You probably won't find one cheaper. $10 ones are ones that give you a code to unlock. Unlocking a MetroPCS/TMO G7Power with the Server unlock app requires a person to remotely connect to your phone and edit your NV files. Currently they are changing the imei to a different model phone that they can generate the unlock codes for. Since they are using a different model phone imei, activating on Sprint Network could be an issue since Sprint is picky as to what phones they put on their network.
If I flash "retail" firmware on a TMO Sim locked Moto G7 power will it ask me for an unlock code that I don't have? Bought it on eBay and TMO says its eligible to unlock but refuses because I'm not the original owner. Bootloader is unlocked.
EDIT: Figured out my issue. Was my fault. Flashed the RETAILUS firmware on my MetroPCS model.
Thanks OP!
Also to add to this, the Metro model is NOT supposed to be compitable with Verizon due to lack of CDMA.... Well Magically the phone now supports CDMA so it has a CDMA radio in it!

Question Can't change CSC from T-Mobile to Verizon with firmware S908USQU2AVDC

A question from a noob here. I have a T-Mobile S22 Ultra phone which is network unlocked. As I recently I switched from T-Mobile to Verizon, I'm missing some of the features that are Verizon specific, while not needing anything that is T-Mobile specific anymore. From what I understand, Samsung installs multi SCS firmware on most of the phones these days, which can be changed by a dialer code. That however did not work at all.
Another option I've come across is by flashing provider specific (in my case Verizon) firmware as long as firmware version is the same (S908USQU2AVDC). There are a number of articles on how to do it by using Odin. The issues is no matter what I do and what files I select (like by using CSC file instead of HOME_CSC with or without flashing USERDATA file as well) the result is the same. It shows success and reboots and then reports an error and does the full factory reset which ends up back on T-Mobile version.
The question I have if it's even possible? And if so what I'm doing wrong here. Unlocking a bootloader is not really an option for me...

In theory, flashing the correct firmware (VERIZON) should work. I would honestly first wipe the device, then flash (clean, not dirty) the Verizon firmware and setup accordingly. I had a similar case with a TMBILE unit (I had changed carriers) and I had managed to use XAA CSC and then when I reverted to TMOBILE SIM it would not "restart and install carrier updates". I had to basically switch the unit to U1 and then revert to U and it finally pulled all the TMO crap.
I may be mistaken since I haven't done this type stuff since S10, but I think you need to first reset the device and flash the unlocked version then when you put the verizon sim in it should provision it. Then you can flash the verizon package if you want the bloat apps. The features may be hit or miss. You may need to activate the features on the verizon website. Some features may never work as the carrier wont push them to IMEI not in their database of branded phones. There may be things you can do in hidden settings with "Activity Launcher" or other methods.
I'm here trying to figure out the same things for Tmobile and a factory Unlocked phone, before I buy.
Thanks a lot for your suggestions guys! I managed to do what I wanted. This is what I ended up doing, first flashed the unbranded U1 version on my phone and on the first boot Verizon sim was provisioned. Then I flashed Verizon firmware and it worked!
