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.

First of all, sorry if this has been answered here, I simply can't find a definitive answer for our S6, let me explain better.
As you may know, I'm not a newbie here or in other forums, I've rooted most of my phones (Not this one) and have installed custom roms dozens of times to all of them, BUT, I'm definitely a newbie about what I need here, I'm trying to see if I can change my SM-G920i region from XSA (Australia) to any other one, India in this case. I have read tons of threads and posts and that's what is confusing me, in some threads there are people saying that they did it and is working great, in that same threads there are people saying that they did it but Knox got tripped, there are others that say that the device is soft bricked and others are saying that they have read somewhere that changing the CSC from it's original one may brake future Samsung pay.
So, this phone is paid by my office, they allow me to do what I want to it while I'm able to just put it back as it came from factory, so that means that I can root it if it doesn't trip Knox, that I can install anything while I can simply go back anytime they need me to, and obviously, Samsung pay works when it finally comes. With this in mind, can somebody answer me a couple of questions?
1-) I know it's possible to do it, but is it true that by doing this I'll have Samsung pay issues? I doubt that knox will be tripped if I do it with odin, but besides knox, is there any possibility that Samsung Pay will not work in certain regions (India in this case) and that's why some are saying that it will break it?
2-) If I download the firmware and flash it via Odin, I'm reading that it won't brick the phone is done via Odin, but in worst case scenario I assume that I can always go back to original one and it gets factory reset, am I right?
3-) If I flash it correctly as I expect an it doesn't brick, does this means that it will change PDA and CSC versions all together, that it will basically become a device from the new flashed region? So if I flash the India one to my XSA (Australia) now it will work completely as an India device and should get future OTA like the rest?
Again, sorry if this has been asked and answered but going back a lot of pages here can't give me definitive answer, thanks in advance for those of you kind enough to answer to this.

Thanks.
In another thread that I have posted (Brazilian one) I was replied to, so because of that I decided to do it, so far everything is working great as expected. Mine was an Australian baseband (XSA), only thing you I noticed is that when I connect it to Smart Switch app for PC or MAC it will still detects the Original CSC, I was curious about it and installed Phone info apk and it shows correctly the information, both PDA and CSC are now from India but it shows that the Original CSC was XSA (In my case), Firmware's CSC code is INU (India) and Active CSC code it says XSA/INU, so I'm assuming that it's showing multiple CSC.
Does somebody know if having the Active CSC showing XSA/INU causes future OTA issues?
After flashing a ROM its good practice to go to recovery mode and do a full wipe of cache and full reset to change CSC to the default of the ROM you flashed.

Well, in that case I think I will pass for now, as I did a Full wipe cache and Full reset before the Flash but just did a Wipe cache after I flashed it.
The issue is that I basically just finish setting everything back as it was before (about 3 hours and I still haven't set my Contacts Ringtones and Accounts links) so begin again it's a PITA. Once I finish this I'll do a full nandroid backup to have everything as I want, but if I do the Wipe Data/Full Reset and then restore from the Full backup, does this put everything as it was including CSC again? I've been always confused about how deep this restore goes in the system files. Do you know about it?
Thanks.
Try restoring from your backup after the full wipe from recovery. If everything works then you should be ok. Otherwise start from scratch and reinstall everything one by one.
Will try that later today, thanks.
Goodluck.

I tried that and nothing, still the same, then I decided to remove the Re-activation Lock in Find My Mobile settings, and after that and enter to recovery mode, it changed the CSC to India, so for those of you with same issues, remember about Re-activation lock.
Thanks for your help.
Did you have a SIM card inserted when you flashed your ROM with removed reactivation lock?
I had the SIM card on the phone today all the time as I forgot to bring with me the SIM removal tool and didn't have anything to open the Sim card tray, but last night I didn't have the Sim card installed when I flashed the ROM.
So today after I did the Wipe cache Partition and Data and saw that it still had the same issue, I flashed a UK ROM into a SM-G925f that had some African country ROM (have never heard of it before in my life but for the name it sounded like an African country), anyways I did that and everything went great, so that's when I thought what was different between the devices and then I remember that I had turned on the Reactivation lock in my S6 and not in the S6 Edge, so I turned it off, then went to Recovery mode and for my surprise the CSC was already changed without any other reset or anything.

can you post a screen of CSC page of Phone ** info ** just for reference?
I see you said that CSC changed to India, but Active CSC or also Original CSC?
What I mean is that, now I have a S6 which has Original, Active CSC as MRU...I'd like to put a European fw on it since I'm based in Europe (got this Middle East / Africa phone just because Dual sim it's not available in europe) but I'm in doubt if putting an european fw will still show that CSC has changed from original one and maybe OTA updates won't work.
thanks
Changing csc!!!
I succesfully installed a G920I indian INU rom in my device which had a XSA rom but when i go to recovery it still shows as XSA ....How do i change that to INU?
Hi i am using a galaxy s6edge+ and i am really struggling with the region lock. I have tried a few options of the factory full reset changing the Apn's to the ones needed and using different sim cards.when it used to go into emergency mode "h+" now it won't connect to any internet at all. Can i possibly have any basic assistance with the rom and resetting options to change the csc when i do a hard reset the csc says it's 'multi'. what does that mean? Any region unlocking help would be appreciated so much!
Thanks guys
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..
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.
SM-G955F Claro Puerto Rico.
I'm currently running a T-Mobile Samsung Galaxy S7 with an AT&T sim card.
Model# SM-G930T.
Android Version 8.0.
Baseband Version G930TUVU4CRI2.
Build Numer R16NW.G930TUVU4CRI2.
I'm wanting to hopefully flash the AT&T firmware to this phone, but I'm not exactly sure how to go about doing it. I've spent about 2-3 hours searching back & forth between the AT&T forums & T-Mo forums but can't seem to find a definitive answer, or definitive guidance.
I think it's fairly simple via Odin once I have the appropriate firmware. But I just wanted to make sure since I'm flashing another carriers firmware on top of an existing carriers firmware.
Everything aside from video calling & WiFi calling is working. I would love to be able to use those 2 features & receive future OTA updates. Any info/guidance is greatly appreciated. Thanks!
No love?
I'd settle for an insulting reply guiding me in the right direction. I just don't want to brick my phone throwing AT&T firmware right over top of T-Mobile firmware.
The rom you are looking for is here: https://forum.xda-developers.com/att-galaxy-s7/development/rom-t3804287
I am using it now and love it. Several options for the install. Can root if desired.

Thanks for the response racer! I'm gonna bookmark that page and definitely save it. Right now I'm looking to stay 100% stock. But I'll definitely go that route if I can't get any guidance on going stock AT&T.

Going stock AT&T is no harder than going stock for any carrier - here is the skinny, using SamFirm 0.3.6, the latest version of ODIN and a S7 of the Snapdragon sort (along with variations for the S7 Edge):
1. Automatic search using SamFirm - the easiest method - SM-G930A (for the S7 edge - SM-G935A) with a country/carrier code of ATT (both phones)
2. Once the firmware shows up, select where you want it stored on your PC, then select Download Automatically/Decrypt Automatically (this performs all the scutwork for you, such as checking for CRC32 errors, as well as separating the firmware itself so you can simply plus the parts into ODIN.).
3.. Once you have the firmware downloaded and decrypted, it's time to put ODIN to work; but before you can do that, you have to do two things; physically connect the phone to the PC, and get your phone itself ready to receive the files via ODIN. The ODIN part is easy - your newly-downloaded firmware is in multiple parts; each part fits in a specific block in ODIN. For the CSC part, you have a choice between CSC and HOME-CSC. Because I tend to make sure nothing is left over from the previous firmware, I choose CSC; this forces the new firmware to start from scratch. Lastly, before sending those files to the phone, you must enable the phone to be able to get them - you have to put the phone into Download Mode. (for all Snapdragon S7s - including the S7 Edge, it is Volume-up, Power, and Fingerprint-sensor (all at the same time)); a sky-blue screen will show, indicating you are in Download mode; this is what you want. Make sure your cable is properly connected, then hit the Start button in ODIN - that's it. (As long as the transfer is successful (which ODIN itself will tell you with a green PASS message) you're done the hard part; the phone will auto-reboot and start the Setup process for the new firmware.
Have at it.
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

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.
Thank you!

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.

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.
