Recover FRP locked S7 - Legit 3/2018 - T-Mobile Samsung Galaxy S7 Questions & Answers

I searched and searched for good information on how to get into a phone that I purchased for a relative that died. My phone, but I made the mistake of not ever logging into the phone before I let him use it.
First things first, if you buy a phone for someone, log into it with your credentials so if it gets FRP locked you can just log in.
Through T-Mobile, Google, then Samsung, my process was going to be get a proof of purchase with the IMEI on it from T-Mobile (the standard purchase info does not have IMEI), email it to Samsung, get a shipping label and send the phone to samsung. 10 days easy, unkown costs.
I found a link to the the SMG930T rom from 03/2017 on this site
https://forum.xda-developers.com/tm.../sm-g930t-odin-restore-g930tuvu1apb6-t3342208
I found a page on the internet for s7 fans called bypass-frp-lock-adb-bluetooth-method-samsung-phones
I used Odin to install all 4 of the files downloaded (one of the CSC files didn't pass MD5, so I used HOME_CSC) I don't know if the CSC matters, but I did need the BL, AP, CP, and CSC, I think.... I thought it hung on T-Mobile Screen, but after a long time, it went onto the next step.
I then followed the S7fans instructions. I had to run it twice because the first time it asked for permission and failed. I also just went to an admin cmd line in the directory where those files were and renamed the .bat file to a short name.
There was an error message at the end, but it didn't seem to break it.
So, your phone is recoverable, I just wish it didn't take me a day and a half to find out which combination would work.
You can probably use a more recent version so you don't have to go through so many OTA updates, but I wanted to be sure it would work the first time.
Oh, and if it fails, try a really good cable. I was pretty sad the first time I tried and it failed.

i put my back to 6.0.1 than called 112 as an emergency number when it dialed i was able to swipe and bring up the internet than i got thr frp bypass apk installed it and signed in on google.com. ran the apk then rebooted and was golden.

That is because FRP locks are carrier-based - data recoveries are via the Internet (therefore, as long as you have wi-fi, you're golden.). I have three backups - and none rely on the carrier; the phone itself, Google, and Samsung, and I don't need a carrier to restore from any of them..

Trying to install TWRP on SM-955F Custom binary(RECOVERY) blocked due to remaining...

Hello.
(backstory, boring) I have an SM-955F from Claro that I've been trying to unlock completely from the carrier. I've had lots of trouble with them and am pending a case with FCC to get out of their claws. In the meantime, I've been trying (without success, hence my posts) to get it working 100% with T-Mobile. I've had T-Mobile for years under a friend's name and couldn't get a device -so I took one from Claro when Puerto Rico was hit with the Hurricane (T-Mobile had no signal for months).
(Little-lot- of info) So, I had the phone updated to Sammobile's PCT 8.0 firmware -G955FXXU1CRC7_G955FOWA1CRC2_PCT-. But it didn't have the OEM unlock. At one point I remember installing TWRP but something happened to the phone and it wouldn't boot up. So, my act of magic (*coughs*, XDA) I found a way to get it back to official firmware (I think at first it was a Germany's 8.0 firmware*can't find the file name*). Anyways, I want to get the phone to have Wi-Fi calling, VoLTE, etc from T-Mobile and, for what I've interpreted, that comes from the CSC files.
Now, I found a thread that uses TWRP+AROMA to get a list of CSC files on the phone and I can just install the one I want. (I don't know if there's an easier way directly from ODIN but I've not found that compatible TMB CSC file for my phone to get the features working, if any).
In any case I still want my phone rooted (I think I triggered Knox, but the phone updated through the Samsung Updater just fine after installing a PCT 7.0 firmware -G955FXXU1AQCC_G955FOWA1AQCC_PCT-. Clearly I'm out of my depth)
(to the point) The phone doesn't want to install my TWRP file. Says "custom binary(RECOVERY) blocked due to remaining installment balance". Obviously it's Claro's side blocking it, I think?. But I can't get them to unlock it (since it's still "theirs", until I get my case resolved or pay their stupid balance. Long story short, Claro's service is **** and I regret not waiting to get my credit approved my T-Mobile)
So, how do I go about it? I read that its RMM blocked. But my state says normal. The OEM unlock only appears on the 7.0 -G955FXXU1AQCC_G955FOWA1AQCC_PCT- firmware (even then it won't let me install TWRP through ODIN). I honestly don't know. I'll appreciate all the help I can get to reach my goal of getting 100% on T-Mobile's features (mainly VoLTE, if possible-the feature is greyed out so I assume it can be activated). Can't even change the radio band on the thing. I read something about using Nova Launcher and having the widgets activate it through "Enhanced LTE" (I think) but that option doesn't appear on the list. I'd also like to delete all remnants from Claro on the phone, bloatware, booting logo and such. Since it's a 955F, I assume one can make it as if international?
Also, please check my previous post, I just realized I forgot to detail something. I did hit that "your phone has been modified, restart to undo process" and I forgot. Maybe that's the root of it all?
Any questions, please do ask. I'd like to get this moving. For now I'll use my Nexus 6 (God I love that phone a lot)
Maybe there's some compensation on this, maybe, if I get it done.
I've included the picture of the error and the info on Download mode, links for files I refer to also at the bottom.

Bump.
I have the same problem "custom binary (RECOVERY) blocked due to remaining installment balance", when trying to install TWRP, in my case I want to install Custom Rom and I could not, I have not found any solution to this problem, I do not have OEM on 8.0, and the RMM status is normal, I could unlock unlock SIM thanks to a friend with Z3X tool, do not charge for it but thankfully I made a donation for the hard work and also that the Z3X is not cheap at all, if you need to talk to him, you inform me to give you his contact.

New g955u won't connect to Verizon

I'm about ready to throw this phone out the window, and hoping someone here can help me out...
My wife ordered a never used g955u off of ebay. It came with Oreo installed. It had the CRE9 firmware installed. We are on Page Plus (Verizon reseller). We put in her SIM card, went through setup, but we are not able to make phone calls. The SIM card works fine on her old phone. I reset the network settings to no avail.
I did a network search and selected Verizon Wireless, but it times out and gives the error :
No Service
Selected network (Verizon Wireless) not available
I talked to Page Plus, and everything looks fine on their end, they say it's something in the phone.
I suspect it's something in the radio settings, but I'm locked out of the service menu. I factory reset the phone, and that didn't fix it either.
I've been down several rabbit holes since then.
I tried to follow the steps in this thread: https://forum.xda-developers.com/galaxy-s8+/how-to/carrier-switch-snapdragon-t3615680 hoping that if they can make non-verizon phones work on verizon, then it can make a verizon phone work on verizon. I also tried to root the phone using this thread: https://forum.xda-developers.com/ga...root-g955u-g955u1-snapdragon-sampwnd-t3658911 hoping to get access to the service menu.
But evertime I tried to flash any of the necessary binaries, I got Fail! (auth) and the phone gave the error:
sw rev check fail : [boot]Fused 3 > Binary 1
or
sw rev check fail : [boot]Fused 2 > Binary 1
Turns out, you can't downgrade. And all the binaries in the tutorials are now downgrades.
Somehow in all this, I managed to flash the phone to CRD4. I tried flashing back to CRE9, but regular Odin fails without telling me what the error is, and Comsy Odin gives a model dismatch fail.
I tried connecting the phone to Kies, but it gives me the error "only the device owner can connect to kies" even though I'm running Kies as administrator.
I've ordered a new SIM card from PP, just in case that fixes it, but I'm losing hope here. If anyone can help me out here, I'd really appreciate it. If there's anymore information you need, let me know and I'll post it.

Yeah, that's what I had figured out. I'm still not sure what direction I need to go in to find a fix for this.

So I know Odin 3.13 at least. But other than that with Oreo I don't know
I wanted to stop by and mention I am having nearly the identical issues. I bought a used Verizon Galaxy S8 from somebody today, and even ensured that the IMEI was supported by Page Plus beforehand. I tried using an existing, working SIM card of mine from Page Plus but found that it did not work automatically as it should have. After going through four customer service representatives, I was told that my phone is somehow not compatible. Still, I think I may have a slightly different situation going on... I was told it would not work because there is no "LTE/CDMA" option in the "Network Mode" setting. Instead, upon inserting the existing SIM into the new phone, my Network Mode setting only has access to "LTE/3G/2G (auto connect)", "3G/2G (auto connect)", "3g Only", "2G Only" options.
When I put the SIM back into my working phone, it gives me the correct network options. For some reason, this new phone is not allowing me to connect to the Verizon network at all.
You've taken a lot more steps than I have... I figured it could be an issue with Android Oreo, but I am really not looking to delve into the degrading process. I will also order a new SIM and see if that magically fixes things, but it's starting to look like a lost cause.
Let me know if you figure something out - you are the ONLY person online I have found with my identical (or near identical) issues. If you happen to know any way around the exact issue I'm having with the Network Mode, that would be insanely cool.

S6 g920v - Locked out of my own phone and cant gain access. Radio off?

Ive read other posts and searched the web but I can't figure out what I'm doing wrong.
I have an old s6 I was about to sell so I downloaded the official 7.0 from samfirm and started installing via Odin. At a certain point in system.bin it freezes for 30 minutes. I pull the plug on it. I'm supposed to meet the guy in 2 hours at that point and I download multiple different vwz firmware for the s6 and eventually am able to boot up again. The problem now is that a stock firmware won't completely work (modem.bin) and the older versions from updato work except for system.bin.
So now I have access to my phone but when I go to login its samsung account locked. I try to type in my username and pass and it says "Invalid ID or password" and I even reset it but it still says invalid. I can see the phone on my "samsung wheres my device" website, but I cannot unlock it because it says radio is off.
Edit: Forgot to mention I tried to update from 6.0 to 7.0. Tried multiple 7.0 firmware and attempted to revert back to 6.0.1. I honestly don't know what firmware i'm on now.
It says im on FA50_g920vru4AOJ2.
I'm in the US.
So im wondering since i've frankensteined these firmwares together, is this radio issue because I've flashed a different vzw modem? When it's plugged into my PC it says device not supported. When do a factory reset I assumed it reset the modem back to factory as well.
I can post pictures if need be of the phone showing up in my samsung account so you don't think I'm doing something shady.

Note 9 (SM-N960F Exynos) incorrect IMEI

Disclaimer: So its not a stolen phone, prior owner was just being nasty. I bought the phone from a 2nd hand shop (Cash Crusaders, Kathu, South Africa), where they told me that a lady sold the phone to them, came back after 3 months and wanted to buy it back for the same price (they guarantee buybacks for 1 month), they refused to sell it back to her at selling price, so she went and had the phone blocked. They went through the process of unbricking it through the ISPs, but in the meantime also got repair shops to try and fix it... They changed the IMEI number... So I bought the phone, fully functional, did a factory reset, saw that it had OEM unlocked and figured it was the cause for the biometrics not working, turned that on and thats where my mission started. OEM locked, custom firmware detected... Used Odin to flash on stock firmware (from Frija), got the phone functional, but emergency calls only and no cellular. I have tried rooting and using console, I have tried changing it in the EFS file, I have tried changing it via ADB Fastboot, via dialer (does nothing even with Google Dialer Framework V5)) no dice, it keeps the incorrect IMEI. I have looked up the IMEI on IMEI.info and its clean, so I take it they managed to get it unblacklisted, which is why I want to get the original IMEI back.
What I would like help with is does anyone know how exactly I can change the IMEI number on my phone (Rooted with Magisk and TWRP, but eXposed framework is finnicky and doesnt register properly, even through I installed the RIRU (V23) and RIRU EdXposed (Canary, both Sandhook and YAHFA on seperate occasions) packages via Magisk (V21.1 and V8.0.3 for manager) as per instructions.
P.S. I am a student on a tight budget, so I would prefer to do it on the cheap/free and I live in Namibia, so sending it to Samsung isnt quite an option.
Also please let me know if there is any info, logs, etc. I can attach that might help.

I have my receipt and they have theirs. So by all means verify the IMEI yourself 356630093456642.

Thing is phone got cleared. Original IMEI is clean, which is why I wanna reset it back to it, only problem is they seem to have used a flash-kit to change it in the recovery partitions too (bricked the damn thing when I recovered it (accidentally turned OEM lock on...), I've tried everything down to loading the engineering combination file (interesting though, its android 8.1, which shouldn't actually be possible to do from Android 10) on it and trying through there, no dice. Also asked local repair shops if any of them have a flash kit, none have 1... So I'm stuck at this point, cant even do the normal 'pay a repair shop to fix it for you' method.

Stuck in a loop between custom binary blocked and downloading do not turn off

I turned off and then restarted the developer's mode in my S7 yesterday. When I went to turn it on today, I got the message "Custom binary blocked by FRP Lock. I used power / start / vol down holding all three and came to a screen that wanted to know if I wanted to download (probably Odin). I then pushed two buttons of which one was the start button (the one in the middle of the bottom) and the vol up button, which started the phone trying to download. It got the message Downloading "Do not turn off target". I figured out how to stop that, but when the phone rebooted, it was back to "Custom binary Blocked ..."
The information I need to download firmware (like the CSC), is either in my phone or not common enough to exist in the country lists with their respective phone companies. My phone is an S7 and probably a G930F, although I can't verify that because I can't get into the phone. I would not mind downloading Odin, but I understand that the information regarding CSC_home with regard to who my provider is and what country I'm in is necessary in order to install Odin and I don't know how to find that information or to find the complete model number for the phone.
Thank you for any advice you can give me. I would prefer not to have to use a factory reset on the phone to get it up and running again.
Changing OEM Lock does trigger FRP sometimes, like 2 years ago my friend had the same on his Note5, it wasn't that hard to solve.
You need to verify your device model (written in the download mode's top left corner), then download a recent firmware, flash it via Odin, after booting, it'll ask you about your Google account and in some cases, your Samsung account, too.
Unless you've forgotten them, you should be good.

Thanks very much. I got the info off the download screen.
Do you mean I should go ahead and download Odin and then hope to find the right firmware? That's giving me part of the problem. I downloaded two different versions of Odin
3_v3.11.1
3_v3.12.3
I think to get the right firmware, I would need to know the country 3-letter code, if the phone is dual sim or not and the service provider? Since my service provider is not among those listed (like telekom or O2), can I use "unbranded" for my country? Or is this information for the CSC entry something my provider could provide?
Also, if I enter that into CSC, will I still have the option for Home_CSC? I'm quite interested in trying to keep my data.
And finally, I don't think I set up any account which had to do with the cloud. If an account was needed to verify the operating system, then I hope to be able to figure out what that was.

It doesn't matter. Any firmware will get your phone booting, that's the point, if it was FRP cause you forgot the Google account, then perhaps you should be picky, but since you're not, then it's fine.
CSC gets activated when the phone detects your SIM card, that's how it knows where you are and that's how it sets CSC features provided for your region. If you pulled the SIM out, it won't apply CSC just yet. If you travelled to another country, your CSC will be changed (once you boot into recovery).
What model your phone has, so I can find you some files?

I'm making some progress. I learned you can get the model number off of the recovery screen which I got to with power / vol up / Home and by waiting for the Recovery screen to appear.
I then found a very close firmware in updato, but the last letter was a y instead of a c, so not the perfect model-number-match. That one with the wrong last letter was for my region in the EU. The actual matching firmware ends with a c and I found that firmware on multiple websites, but listed as being from Thailand.
Now, the strange thing is that I bought the phone in Germany for a trip to Thailand and got it unlocked before I went there. Since I'm in Germany and most likely Telekom, and since I've read to trust no website except Updato, which doesn't have the firmware for my exact model number, I've been wondering how to proceed?
You asked for my model numberOne of the non-Updato websites offers the firmware with a checksum with the file, but since updato doesn't have that firmware file, I couldn't know if the checksum was the right one.
So I think what you asked for was the model which is G930FXXU1DQHC
Thanks very much.

That's a very old firmware, it has U1, latest has U8, I had the same device, too.
A trusted, reliable site would be AFH, search for G930F and find large files, that's the firmware.
Hi,
I found the big file of 1.8 gb called G930FXXU1DQHC_DevBase_v4.3.zip and downloaded it and extracted it to a folder I created myself called odin. It's not what I was expecting. It is a whole lot of folders within folders within folders, but none of the files that I would expect to be able to click on for an installation by odin. I was actually expecting three files that were clickable, which I've seen in instructions that utilize Odin to flash the firmware.
The two main folders it produced were ALEXNDR and META-INF. There's a single file at the same level as these two folders called options.prop.
Edit, I will try to attach a screen shot of what I was expecting to get.
More Edit: I'm not finding an installation file, so I think I'm at the point where I need to install Odin, but I don't know whether I install it on my pc or on my phone and if I should install that before I install the firmware. That's the point, isn't it? That Odin is in place to install the firmware?
Also, I can't see any exe files in the zip file I extracted, so I don't know what could be installed.
What is it I should be looking for?
Thank you. You're helping me keep going.
I see you did not get what U1 and U8 means. For an example, this is the latest firmware for Galaxy S7.
But, you downloaded a U1 firmware, which is very old to be believed. Forget about that, download this one, extract it, and flash it via Odin.
Thank you for that information.
The short version: I'm back in! All the stuff below is my journey which was rocky. Had to do some more internet searches, which brought me to another thread here in the forum:
Can't flash firmware, RQT Closed.
Hi! I need help, I was trying to flash Indian firmware (latest) on my Note8 (N950FD) with french rom. But when tried to flash the rom with Odin, start the procces and less than a minute, finished and appears as success, but nothing happened...
forum.xda-developers.com
For others who come after me:
I downloaded the firmware files, started Odin, put the phone in download mode (power / vol down / home), then plugged the phone into the computer and clicked on the boxes one at a time in Odin and was directed to firmware files in Windows Explorer and clicked on the correct one. I wanted to save my data so in the box called Userdata, I entered the CSC_Home file. They were all accepted. Then I clicked on Start in Odin and after a short time, the scrolling of files on the left side ended. That's where the above link comes in which says to try using a more recent Odin, so I tried again with Odin 3.13.1 (with the Chinese figures).
This attempt went better, took longer and then my phone sat and blinked Samsung at me for a very long time. I finally turned Odin off with Exit and then waited some more while the phone was still plugged into the computer. Then it started installing what it had downloaded. At least by now the little Android robot wasn't keeling over anymore.
After that finished, it asked for my pin and accepted it and I got back to the home screen. It then asked if this was my phone number, which it was. And I could see! that it had a charge of 44%.
I then went into Settings and looked for the developers setting and found that OEM was indeed turned off and that probably caused the FRP lock to occur. I turned the developers setting off for now.
I was able to keep my data with one annoyance. Some of the less standard apps are giving me a pop-up when I open them that says the apps are always on, do I want to close them, and there's a feedback button which simply shuts the popup off. You have to keep turning this off. It seems to affect non-standard apps, so I may have to reinstall those. I'll look into that ... tomorrow.
Many many thanks! It was so great to find someone who knew how to help me! I really appreciate it.
