S7 stuck on samsung logo after software update (Full Stock, No root)

First of all sorry for posting this , I know this has been asked multiple time before but i tried most of the solution without any success.
I am using G930F bought in UAE
For nougat update i flashed first BTU firmware with january security patch
Phone was full stock without root or any modification
today when i check for manual software updates, i found 62 mb security update
I downladed the update and installed it. I didnt check the update was successful or not.
But after some time when i checked phone was stuck on samsung logo and blue notification light was on.
It was stuck there for 10 mins and then i restarted the phone with volume down and power button.
But result was same stuck at boot logo.
i tried to go in recovery.Screen showed "installing system update" then after that yellow mark with android robot showing no command and then it went to recovery.
From recovery i wiped cache partition but that didn't help.
I also tried "run graphics test" from recovery menu. It first showed erasing and then installing system update and then went back to recovery.
Now i am stuck at samsung boot logo.
Is there any way to resolve this without factory reset.
Can i flash odin file without erasing data?
Guys need your help desperately.
Again sorry for long post as i am very stressed out.

Hi mate..
You may have to do a factory reset....
Check this thread , you can flash a stock rom with out losing any data BUT you have to use same home_csc as is installed in you phone. In the thread is explained

Hi mate
From what i read , you flashed with Odin a N BTU firmware , if you had updates it means you have a BTU CSC , follow the thread i gave you flash the firmware they offer there but use home_csc (BTU) this will flash the firmware without deleting any user data

If is not set it will ask you for a password....if is not set aq password you can use "default_password" as password but is important that you know your google account password when you set your phone

Custom binary blocked by FRP lock

Hi there,
I have a Samsung Galaxy Tab A6 (SMT-580) which I bought today. I followed this tutorial to install twrp, ultimately to root the device:
dottech .org/200476/how-to-install-twrp-recovery-on-samsung-galaxy-tab-a-sm-t580/
Everything worked fine and I was able to boot and reboot fine. Until I signed in with my Google Account. After trying to reboot, I get a black screen with the Samsung logo and a text in red saying: Custom binary blocked by FRP Lock. I went back to the store and they advised me to install Samsung Smart Switch to try and restore. In the Smart Switch program I get an error saying that the device is not supported by Smart Switch.
I can get into download mode, not into any other mode. The tablet doesn't start up at all. On the download mode it also says FRP Lock ON.
When I go back into ODIN and retry to install the from above TWRP image, it says operation failed.
Can anybody please advice? I am at a complete loss. Am I supposed to flash the original boot file? Where can I find that for my device? Will my tablet accept that, since ODIN didn't even want to flash my current TWRP image a second time?
P.S. I only read later that you are supposed to change the OEM setting. I didn't. Is that the cause of this issue, and if so, can I do something about it?
Thanks

Hi. Have you got it fixed yet? You need to download and flash stock firmware for your model and flash it in odin. Once it's done you have to enable oem unlock before you flash twrp. Let it be enabled as long as you you have twrp, root or anything custom.

ok, I read this is the place for noobs, so, I too got myself into a FRP LOCK on my Galaxy Tab A6 sm-T280. I use the tablet strictly for flying my drone for surveillance around the rural location where I live. It was having some connectivity problems, so I rooted it to hopefully get enough horsepower to run the DJI Go app. That didn't work so I did a wipe/factory reset, had a problem with the password, and here I am.
I am researching, and gathering the required tools to fix it.
I finally found some guides that are basic enough for me to understand.
I found numerous sites to download the stock rom, but not sure which ones are safe. Suggestions? Also, I am not sure about the country code for the firmware. I am in the USA, and I don't see it listed anywhere. Does it matter? This android stuff is all new and confusing to this old man. I am determined to get this tablet fixed, and would appreciate any and all advice. Thanks, Gary
edit: Will this rom work? : T280XXUOAPL1 using XAA for theCSC? Is xaa the default/generic for U.S.A. ?

Problem with TWRP Recovery v3.1.1 on my Samsung SM-j701M

Hello there
I bought a Samsung J7 Neo (SM -J701M) on another country than mine (Im from Argentina, device bought on Paraguay). Anyway, I started to look another way to get some space on the internal storage and I remember that android had an option to expand it, using a SD Card. Unfortunately, i realize this option is not allowed on samsungs device, but it works (i read it, because can't do it) if you get root user.
So I looked how to do it and i found a group of files
ODIN v3.12
Magisk v.14.5
twrp v.3.1.1 -j7 neo
Im not sure if I downloaded the right files, but im start the process anyway.
I followed point by point
First I installed TWRP Recovery v3.1.1 (which is supposed to be correct to my model) and then already on twrp rom I installed magisk 14.5 from sd card and did wipe data.
Turned on the phone and I restored all apps from a google backups, and I realized I cant find app "Magisk" on the device, so I decided to reboot the phone and it starts to do a bootloop with this error "kernel rev. check fail, device:2 binary:1"
At this point, I failed every attempt to fix this error
I tried installing the last official firmware that i found (and Im not sure if its the correct one)
J701MUBU3ARC2_J701MUWT3ARC1_UFN
And I got this error
"SW REV. CHECK Fail (BOOTLOADER) Device :5 Binary 3:
I searched on google this kind of error, and I found that I have to downgrade the bootloader. And this is why im here beacause I dont know how to do this, and if its works, i don´t know how to continue the process to root and expand my internal storage. So I really appreciate if someone one could help me with this. I can learn fast and I love to do this things by myself.
Thanks for your time!
Fernando

If you have to downgrade the boot loader, it means the firmware you are flashing is older than the one on your fon.
Go to www.updato.com and look for the he latest J701M firmware.
You can sort the list by date and by region.
And the site is download manager friendly ?
Good luck!

Thanks for your answer! One more question about the region. Should I download firmware from the country that I bought the phone or firmware from the country that I am?

Look for your country specific firmware first.
Otherwise Samsung usually has regional software - i.e for several countries in a region e.g. Argentina, Paraguay.

Hi There,
Did you have any luck with your Phone? I have the same exact model but I have Android Version 8.1.0, Samsung Experience version 9.5; Android security patch level -Feb 1, 2019; Baseband version: J701MUBS6BSB3 and like you, I love doing things myself, and I can't seem to abide a smartphone that's not rooted.
I'm not exactly a newbie, I've been assisting devs with testing and such on AT&T SGS3 for quite some time. But I can't seem to find a stable method for rooting for this phone, no one seems to be doing any development on it.
I would love to hear your story thus far.

im needing help myself, i have the SM-J701M (J7 NEO), with android pie 9 official, but the binary is 7 (because Argentina Geniuses of course) and of all the things i tried nothing works, and the only thing they did was brick the phone, so i flash and stock firmnware to be usable again

What have you done? I saw your messages on TG but everyone ignores usually, I had another problem and footbed the solution myself as I got ignored for days.
So, what have you done? Maybe we can figure it out a way to root it, but to avoid telling you things that you may have already done it is better if you let us know your already followed steps.

i tried flashing TWRP like a guide said (Latest version) but then got stuck with a boot loop in the Samsung Galaxy Logo, then when i enter to flash the latest global firmware it didn't work because it was binary 6, so i searched for the version in Argentina that has binary 7, after that i didn't try anything else in fears of getting fully bricked, i was thinking of the magisk canary way of rooting (patching the AP) but i don't know what happen if it fails the flash

Hi, i have the same device, SM-J701M, but when i try to flash the stock, it says that the device binary is 9 and the rom is 8, but i cant find the binary 9 rom in any place, only 8. I have the trwp installed, so I was thinking if I format all data (system and files) and try to flash again, it will work ?
Also im from Brazil (SM-J701MT), and the device was buyed in Paraguay (SM-J701M) too. Should i install the SM-J701MT ROM right ?

Some success.

Ok, guys, I've had a bit of progress with my device Samsung Galaxy J 7 Neo (SM-J701M- Android version 8.01)
On this phone, the option to unlock the bootloader was missing in Dev Opt and I knew that in order to achieve anything I was going to have to unlock the bootloader.
I searched and found that, via adb/fastboot (Google's Platform Tools) rebooting the phone to the bootloader you could enter the code: 'fastboot oem unlock' or 'fastboot flashing unlock' and voila! everything would be fixed...But...my device wasn't even being recognized by "fastboot" ! adb yes but no fastboot! Always the message: "Waiting on any device". Trying to find and install the drivers to do this was next to impossible.
It actually caused me soft brick my device. However, it was a blessing in disguise; I knew what had to be done, I was going to have to reinstall the firmware via Odin. I searched the site (Sammobile - you'll have to create an account.) and found the Oreo and the Pie Firmware, I downloaded both but played it safe and restored my device with the Oreo first.
And lo and behold the option to unlock bootloader was there! No hesitation, clicked that sucker fast!!
Now, I'm running PIE (No one has done a Custom ROM for this baby just yet) and with the unofficial TWRP in the first link below, it's a bit buggy but until they make an official one for us ... I guess we'll have to wait.
Oh! And don't forget to make a backup with Smart Switch!
And pay attention to the advice here:
Code:
1. Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
2. Add each file to its respective field in Odin v3.14.4. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
3. Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + BIXBY
Other options in case first option did not work or isn't possible.
Option 2 VOLUME DOWN + VOLUME UP then USB cable
Option 3 POWER + VOLUME DOWN + VOLUME UP
Option 4 POWER + VOLUME DOWN + HOME BUTTON
Option 5 (Note9) USB cable + VOLUME DOWN + BIXBY
Option 6 (Note10) POWER + VOLUME UP
4. Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC!)
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
5. Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC

I think that's because you have to be specific with the carrier; Orange; Nextel; Movistar...that makes a lot of difference in with the firmware. If you can, check to see what you had before and try that first.

Hey, I noticed we have the same android version and and phone model, I wanted to know which version of Twrp you used . I am guessing version 3.1.1?

It's an Un-official version of TWRP, so the version #( 3.2.1-0) may not count, you can check the links out to get more information.

hola tengo un problema, tengo un sm-j701m binario 11 android 9 y quiero intalarle un twrp pero no se cual descargar y que funcione

Don't know if anyone's still following this thread or even still has this phone but there's been quite some progress with this device. (i.e: SM-J701M) The posts below will certainly help to bring your device up to date re: rooting; flashing etc.

samsung galaxy s7 custom binary blocked by frp lock

Greetings, ever since i tried rooting my phone, i knew something went wrong (i used cf autoroot).
So the first thing i noticed, i was asked to reset the phone or something similar to that, meaning i would lose all my data.
I tried to find a workaround as this had never happened to me before while rooting a phone, and someone had said that i was supposed to download twrp
and change some partition and then change it back. I dont remember what else he mentioned and what exactly i tried doing, i realised it was formatted either way and i had to start fresh. As i setup my phone i went and switched the oem unlock back to "off", as i did not wanna attempt to root again, but i hadn't realised that my phone was infact rooted sucessfully, leading me to my first error after restarting. "Custom binary blocked by frp lock", with absolutely no access to recovery mode at all anymore. Again, trying to find a workaround, i download some stockfirmware that i atleast had hoped was the right one for my phone, after a couple failed attempts of flashing with odin, ( i had gotten various different error messeges on download mode screen such as (REV Check fail device 7 binary 0 and others witch i cannot remember), now im getting a new error screen, stating that an error has occured while updating the device software. I cant flash twrp recovery as the frp lock is on, and the only thing i can guess is that im flashing the wrong firmware, but i cant find a matching code at all.
Its the following: sm-g930fzkadbt
IMEI: 35214310282955
on the back of the phone it says uk yateley, although the phone was purchased in germany.
Im not sure what to do anymore, any advice would be greatly appreciated.
PS: I have managed to get back to the old error screen with the custom binary info, this time with bootloop, by checking the deviceinfo box on odin

Yep you've now learned the hard way not to mess about and read the proper guides.
Anyway "dbt" is just unbranded german firmware. Download UK "BTU" and flash with Odin, it's UK unbranded.
FRP lock means you'll need to unlock the phone with the google account and password that was on it before you started messing about with it.
If you don't know the google email and password you need to read up on how to bypass FRP lock and it's a nightmare.

Thanks for your reply, just a question, will any btu update work? Should i download latest android version btu firmware?
(Also yes, it was stupid of me to try and do it quick but i had rooted 3 different samsung galaxy phones in the past without issues, either i did something wrong or it took something way too specific to do the job, perhaps the phone's unrootable, but thank you either way) :fingers-crossed:

You'll likely only find the last version of BTU think it was August 2019. It isn't updated officially anymore but it'll be fine to use.

OK so i thought it worked but i can only enter recovery mode now and download mode, but cant actually boot the system, it just boots up the battery screen whenever i plug the charger, and never shows the actual battery info, just the thunder icon. Formatting from recovery mode doesn't help either (Note whenever i launch recovery mode it says installing update, then says no command and brings me to the recovery menu) Any ideas?
PS: It fixed itself. Sorry for the pointless edit.

Someone HELP!!!

Hi all,
I'm having a nightmare of a time with my Galaxy S7... For some unknown reason I decided to root my phone about 2 months ago using CF Auto Root.. worked great.. This morning, was having bad lag issues, so I restarted the phone.. as soon as the Samsung logo came up, I got a red message at the top of the screen saying "Custom Binary locked by FRP".. kind of freaked out and booted the phone into Recovery mode.. wiped Cache and wiped phone (to go back to factory setting I guess).. restarted... since then, I had no boot.. it did loop for a while as I was trying to charge the phone.. but that's it.
Now, the only way the phone will power on is if I plug it into my computer in Download Mode. I am trying to flash the ROM, custom or stock, but Odin fails almost as soon as it starts the sboot.bin and the phone screen shows "SW REV. CHECK FAIL (BOOTLOADER) DEVICE: 6, BINARY: 1".. Also, When I try to power on the phone, it HAS to be plugged in to my computer or charger cable and it just loops with a message at the top of the screen.
I can't do anything with this phone and cant find any solutions online... please help! :crying:
PM me for images of all screens please

I had the some problem while playing with my handset I switched off OEM unlock for some reason under developer option..
Next time i reset my handset it stuck on that warning
You need to download combination file, flash it with odin, then unlock developer mode, toggle OEM unlock, than flash back your current firmware, or if you have full twrp back up restore it

Hi all,
I'm having a nightmare of a time with my Galaxy S7... For some unknown reason I decided to root my phone about 2 months ago using CF Auto Root.. worked great.. This morning, was having bad lag issues, so I restarted the phone.. as soon as the Samsung logo came up, I got a red message at the top of the screen saying "Custom Binary locked by FRP".. kind of freaked out and booted the phone into Recovery mode.. wiped Cache and wiped phone (to go back to factory setting I guess).. restarted... since then, I had no boot.. it did loop for a while as I was trying to charge the phone.. but that's it.

This problem appears on the forum over and over. Its a direct result of not understanding what type of S7 you have and what you need to do before modification.
The error you have in Odin means the firmware you are trying to flash is older than the bootloader file on your device. You can never downgrade a bootloader only upgrade.
In your case you need to flash a firmware version 6 or above for your device. So if you have a branded T Mobile for example you will need to download and flash T Mobile firmware version 6 or above. The firmware must also be for your region where you live.
The FRP lock is because you didn't sign out of, or remove the Google account on the device before modification. Its a security feature. It will still appear after you've flashed firmware but as long as you know the email and password the phone will start fine.

Dammit.. I tried to put as much detail as possible in there lol.. obviously I forgot some.. My mistake the Galaxy s7 that I am using is a Rogers Mobile (Canada) SM-G930W8. As for not signing out before modification, omfg, that makes perfect sense.. didn't even think of doing that before rooting.. I appreciate the help!! I will give this a go and see what outcome I get.. Thanks!

[/COLOR]That was nice of you to respond so helpfully, despite you having seen the scenario posted over and over.

The S7 didn't receive Android 9 so the ROM is a custom one. Any issues with custom ROM's should be asked on the ROM thread itself where you got the ROM from. It's quite normal for custom ROM'S to have bugs.
You can try flashing the ROM (Android 9 Pie) again to see if it works. If not there are several different A9 ROM's to choose from.
