[SOLVED] S7 Edge G935FD BootLoop / TWRP Splash Screen Freeze. - Samsung Galaxy S7 Edge Questions and Answers

Update: [SOLVED]
Thanks GOD .. Kies Emergency Firmware Upgrade Solved it. Same Smart Switch Method.
Help Me please. I flashed TWRP to my SM-G935FD with odin preparing to root it.
But i found the internal storage is 0 bytes.
so i can't find zip file to flash supersu or mount storage to PC.
i found a solution, it was by changing file system and go back to original file system.
i tried this, i changed it. it typed Done. but nothing shows of back or home softkeys of TWRP.
So i restart my device to TWRP again but it freeze in splash screen.
I tried Smart Switch it give me message that it can't recognize my device.
Odin give me FAILED (DeviceInfo).
Any Solution? or My Device is dead now?

When using Samsung SmartSwitch it is normal that it says it does not recognize the device after you have tried to root it and failed.
You need to put the phone in download mode and use the "Emergency Software Recovery and initialization" in the Smartswitch software. You will be asked to input your model number and the serial number. It will then return it to stock.
You do so at your own peril.

[help] "firmware upgrade encountered an issue"

I was trying to install an Official Stock Samsung Galaxy S4 GT-I9505 firmware, from SAMMOBILE Link for the firmware I tried to use: http://www.sammobile.com/firmwares/3/?download=26516. So while flashing it with ODIN, I think it just randomly disconnected, but that just bricked my phone. I don't know whether it is a soft brick or a hard brick, but this is what happens to my phone, every time I turn on my phone whether it's done normally, the download mode or recovery mode method I will be stuck on that screen.
So now I typed in the error on Google to see how it can be fixed. Link to the method to fix the error: http://androidcentral.us/2013/09/how-to-fix-firmware-upgrade-encountered-an-issue-on-kies/
Firstly, my computer (running Windows 7 ULTIMATE 64-BIT) can detect my phone, saying the drivers have been installed successfully. However KIES doesn't detect mine. Anyways I still try to do this method where I have to go to Tools -> Firmware Upgrade and Initialization on KIES. I type in my model name: GT-I9505, that works, now I have to do my S/N or Serial Number: RF1DXXXXXXX, so when I press OK it says GT-I9505 doesn't support 'Intialising', so I am stuck have no idea what to do.
Also, while flashing I tried repartition my S4, to remove all of the stuff I had, none important, except my music which I transferred to my PC. Solved, just flashed Official firmware, it now works.
Just separately repartitioned my S4, it works but S4 is now stuck on boot loop, so have to flash a 4.4.2 Official Firmware.

Hi,
Can you get into recovery?
Can you still see your phone in odin?
If so , disable kies (task manager) and try to flash the firmware again.
Wipe data and cache before and after flashing firmware.

Need HelP - ODIN gets stucked while flashing

Hello guys,
I need extremely technical help as no longer know what to do.
I have a Galaxy S7 Edge device, which installed the rom BobCat and everything went well until then.
Later I decided to install another rom to test KingRom that left me unsatisfied, because I thought it had some bugs. Had the TWRP 3.0.0 recovery and decided to upgrade to 3.0.2, everything went well.
At one point I do not remember when or how if was when install back, downgrade to TWRP3.0.0, I do not remember if it was via Odin or TWRP, it happens that the installation stopped halfway. Then unplug the device, restarted in recovery mode and got the following message "E: falied to mount EFS (Invalid Argumen)", I could not restart the device (Boot Loop, and stucked at Samsung Logo) except in Recovery Mode, which also made to stay without IMEI number and Serial Number.
I googled until I came to this tutorial:
http://forum.xda-developers.com/s7-e...ssues-t3379516
I followed all the steps explained, I back up EFS_backup and RADIO_bakcup partitions.
Installed FACTORY BINARY G935, everything went well. After restarted, already had the correct IMEI number but still did not present the S / N.
After all that, i tried to install Stock Firmware via Odin, from here started the problems that could not solve.
In the first attempt Odin stucked in "System" (also used the PIT file with the same CSC ... .i do not know if I was right using PIT?). Restarted the device forcibly, entered the stock Recovery, did a complete wipe and always get this message "E: falied to mount System (Invalid argument), I returned to install Factory Binary, then reboot in Recovery and the same message no longer appeared.
Again I try to install the Stock Firmware and Odin always stucks in System, or NAND writing, or Partition, etc. I've tried various Stock Firmware, with and without PIT files, always without success.
Only Factory Binary that successfully installs. The TWRP via Odin also but when device restarts to enter Recovery Mode always get the message at the top of the display:
"Recovery image signature check Fail"
"Reboot to avoid Warranty bit set."
1. Does the partitions are in good shape? how can I check it?
2- I did good or bad using PIT file?
3- Does the problem is running Windows XP through a Virtual Machine?
4 What else can I do?
In all actions used and am using a Macbook 4.1, OsX Lion 10.7.5, Odin 3.11 Windows XP Professional 32bit through Oracle VM VirtualBox 3.4.38
Device:
Galaxy S7 Edge (SM-G935F) CSC = SWC SwissCom
1st Original Firmware: (I guess was 1?) G935FXXS1APG5_G935FVFG1APF3_SWC
Need help Please
Thank you so very much!

S7 Edge G935F // Faulty ODIN flash // Stuck in Bootloader [SOLVED]

Hi Guys,
today I wanted to flash the latest Stock ROM for my device via ODIN. I've done this many times before and (thought) I knew what I was doing. It is my third Phone frome the same carrier and none of them were branded/ locked devices before. Unfortunatly I wasn't aware that this particular device was locked.
After downloading the international firmware I tried to install it and ODIN got stuck while writing the system.img. After that my phone did not boot up (of course). After that I downloaded and tried to isntall the firmware of the carrier, but I had the exact same issue. When I turn my device on I get to an error screen which tells me to execute an "emergency recovery" via the Samsung smart switch software. But it too gets stuck on some point and only gets me to an error screen.
FRP hinders me to install a custom recovery and the stock one does not allow any isntallations via ADB or SD card.
My qustion is: Does anyone know how I can install a rom from here?
I know that I had to have made some changes prior to the flashing, but as I said I was not aware and an Idiot for not double checking.
Since it is not bricked yet I suppose there must be an answer but I can't find anything.
Thanks in advance
Edit:
After only installing the stock bootloader, I am autmaticly entering it when I boot my devive. On the bottom of the screen is an error message: "dm-verity verification failed...
E:failed to mount /system (invalid argument)"
Fix
For anyone in the same situation: I fixed it.
In the end all you have to do is flash the firmware with the fitting PIT file. If you firmware consists of multiple files and there is a "HOME"-file, flash it with this one first on the AP slot in ODIN. After that the same again just use the AP file this time.
My phone is up and running again now.

have u solved your problem ? This problem i am facing on the s7edge nougat ? Plz help ?
Hey,
look at the second post I made in this thread. There is described how I got my S7 up and running again. I'm not sure if it is a valid solution since it felt like trial and error to me, but I'm writing this text from my S7 so it might be worth a try!
Good luck!

I described everything I did in the posts before.
As soon as you can enter the system again all you need to do is deactivate the locks I was talking about in my first post and perform a full wipe.
After that you can install any ROM you want via ODIN just like you are used to.
If that doesn't work for you, I don't have any answers either.
But again:
Prep work:
1. Download most recent ODIN
2. Download the correct firmware for your carrier (from www.sammobile.com)
3. Download the correct PIT file for your device
4. Put your device in download mode
Process:
1. Extract your firmware if it is a zip
2. Start up ODIN
3. Connect your device and check if it's detected by ODIN
3. Put the PIT file in ODIN
4. Put the "HOME" file of your firmware in the PDA slot of ODIN
5. Press start
6. When finished unplug your device and restart phone and ODIN
7. Reconnect your phone and check if it's detected by ODIN
8. Put all the other files of your firmware + the PIT in the correct slot in ODIN
9. Press start
After that my device booted up but still was, as you described too, a little buggy. So I deactivated FRP, activated USB debugging in the dev options, installed TWRP, performed a full wipe and installed another firmware of my choosing via ODIN (without a PIT file this time).
I am running 7.0 on my device now and it works flawlessly.

Does the TWRP flash complete? Can you boot up the OS after you flashed TWRP? (And did you download the correct version of TWRP for your device?)
As a last resort, you could try and flash marshmallow on your device and see if it works there.

Have you tried to perform a regular factory reset via the OS on nougat? Sometimes that does the job, too.
But as I said. I can only give you my best guess here - my phone worked after my procedure, so I didn't investigate further.
And don't forget: Google is your friend.

Well FRP has to be turned off (the button in the menu is called "OEM unlock, the button has to be set to on which deactivates FRP). You don't mention using a PIT file - did you use one?

S7 Edge Bootloop + TWRP stuck loading Unable to format HELP PLS

Hi, I think I f***** up badly...
I wanted to root my S7 Edge SM-G935F running android 7.0 so I enabled USB debugging and OEM unlock.
I used Odin to flash a CF auto-root I found for the 935F for android 7 and the site just said I had to install SuperSU after that but it was just boot looping.
After that I installed TWRP for my phone and installed the zip with Superuser. I kept receiving the error "failed to mount /data (invalid argument)".
I googled it and found a video that said I had to change my system "file system" from EXT4 to FAT. It was stuck so I rebooted the phone...
Now I can't load TWRP (it's stuck at the loading screen) to do a factory reset and when I do a normal boot it doens't go further than the S7 Edge screen, it doesn't go to the flashing SAMSUNG screen.
Now when I choose to reboot in Odin mode it says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
I tried to do that but it says "unsupported device" and it doesn't see my phone in the Emergency Software Recovery tab.
I could have done a factory reset before but it's not the first time I root a phone and I never had a problem so I didn't back anything up but I have some very important pictures on my phone for school.
I enabled adoptable storage so I couldn't just take out the 128gb Samsung Pro + micro sd and copy the pictures on my pc.
Can somebody please tell me how to factory reset my S7 Edge even if I lose all my data. Sorry for my English it's my third language.
Thanks in advance
If I can remember correctly the "An error has occurred while updating th......." screen is actually the same as download/odin mode, so you can odin flash back stock rom.
Your data has probably already been lost during file system changing which automatically format /data.
Also I have never seen any phone run on FAT file system. S7 only support EXT4 and F2FS(required custom rom and kernel). So be careful next time.
AFAIK, there's currently no root available on stock nougat touchwiz rom unless you use modified kernel&rom.
For TWRP to be able to read /data.
/Data need to be FORMAT in TWRP once to remove encryption, so that TWRP can read it.

yeah iv done the same

Can't flash any Firmware after installing Factory Binary

Hello guys,
I need extremely technical help as no longer know what to do.
I have a*Galaxy*S7*Edge*device, which installed the*rom*Samsung Experience 9.0.
Later I*format data to exfat and it doesn't work. After then I flashed any Nougat Firmware and lost my Imei and Baseband.
Number.
I googled until I came to this tutorial:
http://forum.xda-developers.com/s7-e...ssues-t3379516
I followed all the steps explained, I back up EFS_backup and RADIO_bakcup partitions.
Installed FACTORY BINARY Firmware for G935F, everything went well. After restarted, already had the correct IMEI number but still did not present the S / N.
After all that, i tried to*install*Stock*Firmware*via Odin, from here started the problems that could not solve.
In the first attempt Odin stucked in "System" (also used the PITfile*with the same CSC ... .i do not know if I was right using PIT?). Restarted the*device*forcibly, entered the stock Recovery, did a complete wipe and always get this message "E: falied to*mountSystem*(Invalid argument), I returned to*install*Factory Binary, then reboot in Recovery and the same message no longer appeared.
Again I try to*install*the Stock*Firmware*and Odin always stucks in*System, or NAND writing, or Partition, etc. I've tried various Stock*Firmware, with and without PIT*files, always without success.
Only Factory Binary that successfully installs. The TWRP via Odin also but when*device*restarts to enter Recovery Mode always get the message at the top of the*display:
"Recovery image signature check Fail"
"Reboot to avoid Warranty bit set."
My Question also is: What do I wrong? Or is my Phone bricked?
Device:
Galaxy S7*Edge (SM-G935F) CSC = DBT = Germany
I really need help, please.
I am facing same problem with my s7 edge g935fd. But in my case i lost imei of both sim cards & lost baseband version. I tried z3x samsung tool. But i didn't found model g935fd there.
Waiting for help
I am having the same problem with an S7 (G930V). During one of the re-flashes, I was able to install the Samsung Product Info App. The CSC product code came up as blank. Not sure if this is normal for this state. Any leads would be appreciated.
