Stuck in a boot loop even after flashing to stock from odin.

I was using stock firmware and all of a sudden today the phone stuck into a boot loop. I flashed the stock firmware all the way back to 4.4.4 with Odin but right after the successful message I get on odin the phone restarts and it gets into the same boot loop. I suspected it might have been an issue with the partition since when I first got the phone 6 months ago I used a pit file in odin (I know I shouldn’t have) but the phone still worked fine. Now I googled the N910F+pit file, downloaded the first pit file I found, flashed it together with the kit kat stock rom but the results are still the same. I’ve tried flashing the stock lollipop rom for my Country and different countries with the same result. I have also tried flashing CF-Auto-Root and TW but odin gives an error and I get an error on the phone as well. One error that I have gotten which was not consistent since I can’t reproduce the result was “Custom binary blocked by Reactivation Lock”.
I would really appreciate any input.

I'm in the same situation exactly. At the moment I'm trying to download UK 5.1 to play with odin once again.

did you manage to fix it?

It looks like your problem is that you forgot to turn off the samsung activation lock before flashing. If you forgot what that is see this I have not used this feature on my phone; however, I would suggest wiping with odin then flash the official stock ROM for your phone that you previously had on it when it did work, hopefully it will boot then login to you samsung account when it asks you about the reactivation lock. There are some activation lock bypass methods out there if you do a quick google search. Hopefully this will point you in the right direction.

The reactivation lock is indeed on. "Reactivation Lock(KK): On"
I have no way of turning it off since I'm stuck in a boot loop no matter what firmware I flash through Odin.
Any other suggestions?

I have same problem on my SM-910H
This problem was after updating 5.1.1 and isntallind micro-sd card (128gb)
In 4-5 days after this, bootloop began.
I deisntalled micro sd, checked it in computer for mistakes, fixed it and after this phone worked fine.
Today same problem, but when I deisntall micro-sd my problem does not go away.
I downgraded phone to 4.4 - does not help
Data wipe, cache wipe etc - does not help...
Waiting for solution from proffesionals (

Do this, it worked for me. In ODIN, just AP/PDA Autoroot md5 file. It will not be successful and you will get "FAILED" message. Disconnect the phone from PC, pull out battery. Reinsert the battery and boot.

The same happened to me.

To all with this problem. My history:
1. Suddenly my stock device go in bootloop
2. Tried to flash it with official software it does not help
3. Tried to flash it with 3 or 4 file service firmware - did not help
4. Service center (not official, that was service center of my internet market) falshed it with some firmware and sad do not update it. It helped for 2 days.
5. They replaced the motherboard. Only this can help.
So, if you have bootloop in your stock device - try to falsh it with firmware if it does not help - take it to service center and say that they do not spent their and your time and change device or mother board.
Now its ok, working fine.
Wrote it because I spent a lot of time to repair it and maby it will help to some one.

Stuck with no network (IMEI and Baseband are also Uknown)

Here is my full story:
I bought my phone locally (never used) and the phone came with a Fido (Rogers alternate company) sim card but I never used that sim card inside the phone. I discarded the Fido sim and inserted my Koodo Sim (Telus alternate company)
I started with G935W8, on my phone box it says G935W8VLU1APG1 I was at 6.0.1 with latest updates in Canada, I wanted to try the official stable nougat ROM by ambasadii for SM-G935F .
After going through all the steps I find out that I do not have network connection when I boot to system. I asked on the ROM thread and was told "You should not have chosen the option in aroma to flash" which I don't know what it means and that I need to just flash the BL and Modem for Rogers.
I downloaded Rogers firmware and XAC Canada for G935W8 firmware to try. I extracted only BL and CP and tried to flash them with ODIN. It failed with both rogers and XAC and I get the following error. I tried flashing CP only and it worked but when I rebooted I still have no network. I tried flashing CP, BL and CSC and it didn't work. I checked and my IMEI and baseband are "UKNOWN".
I checked my root status and it said no root, I checked and I did not have supersu which got me confused because I thought it came with ROM. So I went and flahsed SR3-SuperSU-v2.79-SR3-20170114223742 with Odin and now root checker says rooted.
I tried to back up with 2 different EFS software but they both can't access EFS.
I tried this fix (Guide A) but it failed (I tried for G935W8, should I try for G935F since my phone is on that ROM?). I did not try guide B since I can't backup EFS and I don't want to mess things up.
This is my current phone info using the app
I wouldn't mind paying for your time to help me if you can guide me on skype or just writing the steps.
Will appreciate any help.

Update: Backed up EFS using TWRP and attempted the fix. I got stuck on Factory Binary unfortunately, it keeps looping.

you do not have a proper modem flashed! your baseband should show DPLT too, otherwise you won't get any connection...
try if flashing latest Helios rom works, it should flash the modem also! afterwards you can return to your existing rom!
if not, you have to search for DPLT modem.bin according to your CSC and flash it with odin!
hope this helps!

Update after messing around in recovery and factory resetting factory binary started working and I restored my IMEI!!
Now I have to figure out how to go to stock

can you help me please. I have the same problem with my G930F. I had the superman-rom.zip and installed it through the manual on xda and now I have an unknown imei / Baseband and no sim. How did you solve this? I've been struggling with it for days. My thanks already are huge.

REcommended step is Just install the latest stock from sammobile(its too slow) or from here samfrew.com which is too fast.
but you can try below
i have lost IMEI as well when i update my BL boot loader. and then i installed CP provided by someone and got it back,
check page 156 and 157.
https://forum.xda-developers.com/s7...-devbase-v4-1-multi-csc-safe-t3591647/page157
just update both bootload and CP.

Thank you but I have already fixed couple of days ago. I Flash The csc and de module from the Stockrom Everything working Again.

SM-G550T1 boot loop "Custom binary is blocked by FRP Lock"

I had used TWRP to install SuperSU to root. This seemed successful, but a day or two later the phone had powered itself off, and on power-up loops displaying the tiny red "Custom binary is blocked by FRP Lock" message. The phone will boot into download mode, but won't enter recovery mode.
I tried repeating the install of TWRP using ODIN 3.12, but now that fails. Tried installing factory images (\BL_G550T1UVU1APF1_CL8180604_QB9902404_REV00_user_low_ship.tar.md5 etc.) w/ ODIN, and that fails too.
Is this an indication I don't have the latest image files? ODIN messages below:

Reviewing other threads I found a not that talked about installing only the "AP" file using ODIN. That seems to have worked.

what worked? and what firmware. I have 2 on5's one sm-G-550T and a sm-g550T1 that both ended up with the "custom binary blocked by FRP lock" on the same day..
Please help!

I just tried a bin I downloaded from S U site and it didn't work. Gotta love the On5 lol.

Custom Binary Lock
The same happened to me: i have not found a complete solution, the closest i get to anything is; i put the On5 in Odin3 v3.12 and select the AP option and putting the recovery.tar file and running it. it goes good till its done and the result is Custom Binary (recovery) blocked by FRP lock in green letters. but still no success. i have tried trwp recovery, the home.tar file, each file by them selves and having trouble. i may not be an expert at this type of programimng but i pick things up quickly if there is any solution to my problem please let me know. thx............ by the way i have also tried kies and wont connect to it as well

Same Problem FRP Blocked Bootlooping
I did all the same as you and have the same problem. Everything was fine till the phone got restarted.
XDA HEEEEEEEELP!!

You need to reinstall the firmware using Odin. Then, when you root again, you need to make sure you have oem unlock and usb debugging on in the developer options. Not having those on and rebooting when rooted cause the custom binary problem.

my S7 edge bricked?

Can someone help me with my issue. Im getting error "sw rev. check fail. device: 2, binary: 1" when flashing back to 6.0.1 stock rom.
This is the log from Odin. I accidentally flashed a 7.0 stock firmware and cannot get back to 6.0.1 anymore.
my model SM-G935FD, came from Dubai UAE manufactured in Vietnam.
My phone frequently freezes on samsung logo when booting up and restarts then goes to bootloop.
My phone has also heating on the right front side of the screen when booting up. Is my phone having fried motherboard already?

U probably updated, bootloader and cp.Flash again 7.0,and then flash twrp,and install custom 6.0.1.

As mentioned, your 7.0 before you tried flashing back to 6.0.1 was with bootloader ending DRA#, that's why you have this error.

Thank you for the response, Yes I think having an newer version of Bootloader wont let you flash back to the previous version because of that error :

You still can flash back, but you need to use newest bootloader and modem files, where CSC and AP files can be from older firmware. I got back to 6.0.1 that way, although vibration no longer works. It works only on 7.0

My phone wont let me get into the Setup stage, it automatically freezes on Samsung logo whatever official rom I install. Do you think its a hardware issue?

There is a possibility, but you have to flash the newest possible firmware with the CSC version you had before it stopped working (so before first flash).

Bricked S7 Edge? AT&T

Hey folks, not quite sure where to turn from here or if this phone just goes to the dump...I was looking originally to unlock the AT&T S7 Edge I have and give it to a coworker who is on Verizon. Come to find this is a much larger task than I anticipated.
Device info: Galaxy S7 Edge AT&T SM-G935A
I attempted to follow the guide which started here: https://forum.xda-developers.com/verizon-s7-edge/how-to/odin-stock-nougat-firmware-t3570156
I downloaded the Samsung drivers, Odin v3.12.3 Patched, and the corresponding VZW firmware which I was under the impression was correct, from https://updato.com
I loaded Odin and the phone, ran the installer, and it looked kosher. The device passed, and it began to reboot. However, after that, it got stuck in the nightmare of recurring boot. I entered recovery mode, cleared cache and tried doing a factory reset, to no avail. Device keeps rebooting. Tried re-flashing firmware, no luck.
Where I got to:
On the downloading screen on the Edge:
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-6935U <- (this seems wrong given it was AT&T, but I could be misinterpreting as I requested to have the device unlocked from AT&T and the person attempted activating on Verizon before all this)
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: OFFICIAL
WARRANTY VOID: 0X0
QUALCOMM SECUREBOOT: ENABLE
RP SWREV: B8(2,1,1,1,1) K8 K8
SECURE DOWNLOAD: ENABLE
If I attempted to rerun any of the dozen or so firmware versions I've tried, I always got the following two errors:

On the device:
SW REV CHECK FAIL : [aboot] Fused 8 > Binary 4
After several hours I managed to get the phone semi-working.
I installed the G935UUEU8CRJ2 firmware from the web. It's the only one it would take as far as I can tell.
However there are two issues:
1. The device keeps restarting after 1-2 minutes of being powered on.
2. The firmware seems to be somehow Sprint? That doesn't make sense...
Android version: 9.0.0
Samsung Experience version: 9.0
Baseband version: G935UUEU8CRJ2
Kernel version: 3.18.71-13710210
Build number: R16NW.G935UUEU8CRJ2
Knox version: 3.1
I've tried running the factory reset from the GUI, but that didn't fix the restarting. Using the reset cache and factory wipe also did not fix the issue. Furthermore when booting into recovery mode initially it attempts to do a system update, then up pops the dead android with x's for eyes and the notorious yellow triangle, yet I can still access recovery mode after a few seconds.
Any suggestions?

There's a password on the file.

Update: I found the password. The ROM worked. It's back to AT&T. That solves my softbricking issue, but the original idea to switch it to Verizon is still at hand.
Is there any way to successfully do this?

No worries. I actually found the correct VZW ROM (For any of those looking in the future it's: G935VVRU8CRJ3-StockROM-G935V-(-BIT
I loaded this using "Odin 3.13.1 Patched" (The SHA256 bypass). It installed successfully and works now on Verizon's network.
Thanks for the assist!

I found this thread searching for a way to restore my AT&T branded Samsung Galaxy S7 Edge(SM-G935A), which I thought I might have bricked since it was stuck in a boot loop. Using the stock rom I found on this thread, I was able to get the phone going again. I spent many hours searching and trying different roms, and this was the only one I could get to work. It was FRP locked, but I knew the password. Just could not get past the loop to enter it.
Thus, I wish to say thank you for posting this thread, without it I would still be looking at a boot loop!

friends will have one for bynario 9 I have the same problem please
