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?

unlock bootloader SM-G901F DTM

I am looking for a way to unlock the bootloader on my Samsung Galaxy S5 Plus (Sm-g901f, kccat6) with German t-Mobile branding (DTM) in order to flash Lineageos on it.
Is there a known way (executable for a newbie in Android flashing)?
Unfortunately my handset does not have a "OEM unlock" button in the developer options.
Is it possible to verify if the bootloader is locked apart from flashing a custom recovery and checking if it has been installed persistently?

i think you just have to flash twrp. if i remmeber correctly i had the same message that my bootloader was locked with my s4 i9506 back then

Even though my answer was posted a month ago, I want to present my solution:
As I said above, flashing TWRP did not worked on the way that all installation guides told me. But not because my bootloader was locked, the reason seems to be a bug (or is it a feature ) in TWRP.
The problem was, that the Stock OS is overwriting the bootloader on the first normal start.
What you have to do in order to prevent this mechanism:
1. Uncheck Auto-Reboot in Odin.
2. After Odin shows "PASS" shut your phone down and reboot it manually to the recovery.
3. In TWRP select Reboot and then System.
4. Done.
Now I am a lucky user of a LineageOS powered phone.

ooo yes thats a common odin bug for some phones..

2. After Odin shows "PASS" shut your phone down and reboot it manually to the recovery.
3. In TWRP select Reboot and then System.
4. Done.
Now I am a lucky user of a LineageOS powered phone.

Why to shut down ?
When Odin passed !
Press download mode command keys
When screen goes black
Immediately press recovery commands !
And if u failed to reboot to recovery,flash firmware with nand erase all option !
As i experienced this issue!

[GUIDE] Root For Samsung Galaxy J5 Pro SM-J530F

Here's another rooting guide for SM-J530F/DS (Dual Sim) stock ROM. Even with Lineage OS my hardware model (ordered March 2018, EU SIM card only) tends to mute the main speaker after rooting. This rooting method works for me and is based on the work of others, especially ananjaser1211 and Abdullah_a86.
Make a backup of everything and make sure that the backup is usable. You are responsible if following this description and flashing bricks your phone. It did work for me which does not mean that it also works for you.
Enable Developer options. (Settings, About phone, Software information, tap a few times on Build number)
OEM unlock the phone. (Settings, Developer options, OEM UNLOCK: enable - otherwise you will bootloop)
Reboot into download mode.
Flash J530F_TWRP_3.2.1.0.tar (in AP) with Odin.
Now TWRP is installed and you should be able to use your phone as usual or to boot into TWRP recovery.
Rooting will erase everything, verify your backup again unless this is a new phone.
Reset the phone. (Open Settings, About Phone, (Looking for something else?) RESET, Factory data reset, Reset, DELETE ALL)
Reboot into recovery, a cleanup script will run and reboot after a few seconds.
Reboot into recovery again, install SuperSu and reboot (wipe nothing).
Starting takes a little time, after running the initial setup SuperSU is installed and the speaker works as expected.
I started here a few times after no-sound, no-root and/or bootloop experiences with LineageOS, CF-Autoroot and Magisk. If you upgrade to this firmware version you can no longer downgrade to a previous firmware version. Follow this only if you break something, want to un-root, update your firmware and/or start from scratch:
Force a reboot if necessary and then boot into download mode. All data on the phone will be lost.
Flash the J530FDBT2ARB3 firmware with Odin (AP*, BL*, CP* and CSC*. Do not use HOME_CSC*).
Now you have again a phone with stock firmware without root.

I think this might fix you booting into download mode problem try this post. Read "how to fix" near the bottom. Please Thank us if it does. This same thing happened to me and I wish I stumbled across this earlier because I figured this out on my own by just messing around going from recovery to download mode and it eventually fixed itself.

Bricked S7 Edge?

Recently, I turned off developer options in my rooted S7 Edge (SM-G935FD). Idk if that is the cause, but after rebooting I got the error "Custom Binary Blocked by FRP Lock". I couldnt boot into my recovery (TWRP) either. I was running on Oreo btw. I watched some Youtube guides and apparently the solution was to flash stock rom. So... I flashed an Oreo Stock Rom on my phone via Odin. I thought that would solve my problem, but instead it made it worse. It didnt give me the Custom Binary Blocked by FRP lock error but my boot screen is stuck at the boot animation (not a bootloop). I could boot into the stock recovery tho. I tried a factory reset, that didnt make things better. I could also boot into download mode. I thought I made a mistake, so I flashed like 5-8 times with both CSC an Home_CSC. The result was the same, it would get stuck at the boot animation. I tried flashing TWRP via Odin too, but it said "Custom Binary (Recovery) blocked by FRP Lock". I tried sideloading that TWRP file to my device via ADB. It gave me an error too (I think "Cannot flash from external devices" or something like that) I thought flashing with Re-partition and Nand Erase On would solve my problem, so I tried that, but it didnt work. Im running on Binary 3 apparently. Is there anything I can do?

I still have the "FRP Lock: On" on download mode, so I tried bypassing FRP lock via binary 5 combination firmware and flashing a binary 7 stock firmware. This time, it doesnt get stuck at the boot animation, instead it redirects to a screen with an android face saying "Installing System updates". A few seconds later, it says "No command" with a dead android face. Then it reboots and the same thing happens. Basically a boot loop, but in a different way. I cant seem to boot to stock recovery either. The worst thing is that I cant even turn off the thing. I have to leave it loop for the entire day until its battery dies

That is what I literally did. I flashed a combination firmware, factory rested my entire phone, turned on developer options as well as allow usb debugging, attempted to reset FRP via Z3X Samsung Tool Pro and finally flashed a stock rom. And, the result is this. A bootloop with an android face dying. I did manage to enter a different screen by pressing volume up once along with pressing volume down and power button. It said "could not open recovery_because_no file directory" and had some more errors. The thing is....I made it worse at the first place. I could have flashed a room with binary 6 or lower, cuz at least the combination firmware would have been available to flash, but my stupid brain did not think of that. I flashed a binary 7 stock rom and there is no combination firmware with a binary of 7 or more. Which means, I will most likely get the "SW check fail Device: 7 Binary: 6 " error while flashing.

If the device is still entering download mode, install the recent version of stock for your device. Maybe that will solve your problem.

the "no such file or directory" error is due to either having had removed stock recovery in flashing the firmwares or the factory recovery corrupted due to likely the same reason. Just flash a revision 7 firmware for your phone and it will at least boot

I have literally flashed the latest stock rom for my device and my country which is G935FXXS7ESK8.
I am a bit confused tho...I am not sure if my device is SM-G935FD or SM-G935F. The download mode says SM-G935F...but this phone used to work with a SM-G935FD rom back in the days. Is this causing the problem most likely? And btw the repair shop said they cant fix it too

I am somehow relieved to know that someone else on this planet is on the same (EXACT) boat as me....this is what we get for messing around too much with our phone hum?
1 - After booting up my phone I get the blue background with a dead Android and "No Command" message
2 - I tried accessing recovery by pressing Power+Home+VolumeUp, but all I get is a black screen with a wall of code lines with "fail to open recovery_cause(No such file or directory)" at the beggining of the text.
3 - "No problem! I'll just flash TWRP with ODIN and install a custom ROM and be done with it!".
..NOPE! FRP(factory reset protection) is ON!!! I cannot install TWRP
4- I've tried to find a combination file with binary version 7...but looks like the internet doesn't seem to care about the good ol' number 7...All I can find is binary version 6.
What Im trying to do now is creating my own combination file binary version 7 (if that's even a thing...) from a stock firmware. But I'm not getting any luckier down this path.
Looks like we need a hero...:crying:

No luck over here friend...
Desperate times require desperate measures. Have you ever tried flashing combination files from different S7 Edge versions?
I can find files for the G935A with a revision 7 of the binary...Im thinking flashing it into my G935F and see what happens. I've read the risks associated with installing firmwares from other phone versions, but I'll have a paperweight either way.
I'll keep this thread updated.

Doesn't really matter if you have a F or FD. I'd say you flash the latest stock rom for G935F or FD(which ever is latest) for any country regardless. By this you should be able to boot and won't get any odin errors.

Turns out, its a hardware problem with the storage. Replacing the motherboard might be the solution I think. :/

I had solved my phone last day
At first u can flash ur phone to leatest stock rom. Then u have to turn of frp lock. Then u will able to boot up your phone. If u cant fix u can knock me on facebook. (If u r a z3x user). Bcoz u need z3x for bypass frp with ufs cable.
Im also using s7 edge.

Does it matter if I use the cracked version without box. And no, I dont have the ufs cable. Is there anything else I can do?

Hi guys, I have the exact same problem with my S7 edge from T-mobile (g935t). Odin will only accept for flash the latest rom and after flash it reboots but I get BSOD. I tried a pit file also from an old g935T rom which was android 6.0 and I managed to get into recovery for a moment and I did a factory reset/wipe cache but after reboot entered again in a black screen and the blue led was lit. I finally removed the battery to turn the phone off. I can still enter download mode but is there anything else I can do to resurrect the phone?

Samsung s7 edge (g935f)
Hi everyone , please am having issue of NO COMMAND and i cant boot into recovery. My oem is on so i cant install twpr neither. Am on binary u8. Please any solution to recover my phone?

Very very good new guys...yep you guessed it right. I was able to fix this problem.
How you may ask? Follow these steps
Note: Make sure you have enough battery. Lack of battery charge in my case caused alot of problems.
1. Download a U7 Rom for your SM-G935F or SM-G935FD
2. Extract the Rom as well as the AP
3. After you extract the AP, you will be greeted with boot.lz4.img , recovery.lz4.img , system.lz4.img & meta-data
4. Make a backup of recovery.lz4.img and meta-data just in case. Also, make a copy of boot.lz4.img and rename the copied one to recovery.lz4.img. Don't forget to delete the original recovery and meta-data
5. Now, you should be left with boot.lz4.img , (modified) recovery.lz4.img and system.lz4.img.
6. Now, download this https://www.mediafire.com/file/ah20ha869prdkkc/Autotar2.0_By_FixFirmwares.com.rar/file
7. Now, make a .md5 file that contains (modified) recovery.lz4.img and system.lz4.img
8. After you are done making that .md5, flash it along with CSC, CP and BL.
9. You should directly boot into your device, (if you do), charge your phone for a while if the battery is lower than 20%.
10. Then, go to the settings and enable OEM Unlock before doing ANYTHING
11. Then, reboot to download mode and flash TWRP
12. Download the no-verity-encryption.zip
https://zackptg5.com/android.php#disverfe
13. Allow system modifications and format data (NOT WIPE)
14. If that doesn't work, go to TWRP, connect it to your PC and copy the no-verity-encryption.zip file and install it
15. If that still doesn't work then, follow this tutorial
https://www.google.com/amp/s/forum....niversal-dm-verity-forceencrypt-t3817389/amp/
16. Then, you should boot and yea...enjoy ?
If this method doesn't work then, you need to try different combinations.
Try packing these files in AP
1. Boot.lz4.img, (Modified) Recovery.lz4.img & system.lz4.img
2. (Modified) Recovery.lz4.img & system.lz4.img
3. Meta-data, Boot.lz4.img, (Modified) Recovery.lz4.img & system.lz4.img
If that doesn't work, I'm sorry this is how I fixed it. ?*
For anyone wondering how I fixed it well, firstly a HUGE THANKS TO @shah22 & @Tapas27sTapas2. This would have been LITERALLY IMPOSSIBLE WITHOUT THEM. So, basically I tried an AP with renamed recovery.lz4.img and system.lz4.img only along with CP, CSC and BL. Due to my phone having literally 0%, this journey was very difficult.
Feel free to ask any question
