Put the phone in download mode, use Samsung Smartswitch to reinstall stock rom

i have already done that , it stuck on modem part , secure check radio fail and when i flash without modem , it successfully flashed but root issue , when i flash twrp , it doesnt boot into into twrp and stuck on logo?
I do not believe that you see a "modem" part when using smart switch? Otherwise use Samsung Kies for S7 edge. And do the Firmware Upgrade and Initialization menu item

yes i have enabled that and also usb debugging
What to do : Reflash the stock firmware , after that is completed , turn off the phone , and install on your pc : the No verify Opt encrypt 5.0 from here:
https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-5.0.zip
And the SuperSu file from here :
https://download.chainfire.eu/supersu
Now go download the latest Odin, and connect your phone.
Flash the Twrp 3.1.0.0 ( be aware to choose the file for Hero2lte) and reboot to recovery.
DO NOT LET IT BOOT INTO THE SYSTEM.
IF IT DOES , IMEDIATLEY CLOSE THE PHONE AND BOOT INTO RECOVERY .
Once you are in recovery , firstly go to wipe and do a factory reset .
Then connect your s7E to the PC while you are in the TWRP , and copy the SuperSu file and the verity opt oncryption to the storage.
Note: if you have an SD card inserted , copy the files to the SD not the internal storage.
Now , pay attention , If you don't do the next steps in the right order , you may brick your beautiful 800$ phone.
So pay attention , you have to firstly run the No verity encrypt file.
After it's done, go back >reboot>reboot in recovery.
Now search the file and run it (the SuperSu file)
It will take a bit longer to flash the SuperSu.
After it's done , reboot
Note: your phone should reboot 2 times , If it doesn't or it reboots more than 3 times, CLOSE your phone , and repeat the whole process.
IF your phone reboots 2 times , your are good to go .
The first BOOT May take some time (usually around 6 minutes) and it may loop a couple times, DO NOT INTERRUPT THE PROCES !
IF your phone boots up successfully, configure it and run a root checker , it should say : congratulations your device is rooted.
IF IT doesn't, well you have had to mess something up during the process.
Hope that helped , let me know if it did

I had the same issue to fix.
open smart switch and use the emergency initialization and recovery feature.
it will ask for your model and serial number which is on a sticker on the back of your phone.

I have tried that , that also stucks in the modem part and give radio fail secure check error , i cant even flash it , i was thinking i will root it and install a custom rom but it cant boot to twrp , and if i just flash the AP part then the device boots successfully and the imei and baseband everything ok . Just the hidden codes not work , its really a weird issue , im really confused about it
suhaibahmad. When you refer to "whenever I only flash AP"you are referring to using ODIN, NOT SMARTSWITCH. There is a difference.

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

Installing TWRP

Im posting it here bcuz i cant find my phone model btw my phine is samsung j7+ (c710f) i tried may tuts how to root j7+ and am always stuck installing twrp. In odin it says pass but when i tried to go in recovery mode for the first time i always got this messsge (warranty bit recovery (0) ) on the top of the screen and my phone restart and load fine and when i try to go back in recovery this will show
No command

Failed to recovery cause no such file or directory

S7 UFS sudden dead?

Hi there,
I got an old man's S7 Edge (SM-G935F) and I'd like to help him rescuing his photos (he doesn't have a periodic backup but he learned from this now).
The phone did stuck at the boot screen. He didn't try to modify anything.
FRP Lock on unfortunately. Should be the latest Android.
I can enter the download mode (not the recovery) but no chance for TWRP b/c of FRP. Same error for an engineering recovery I found online.
AP SUREV: B:8 K:B S:7
So I got me two OEM firmware packages with Frija and try to reflash but it always stuck at flashing "boot.img" endlessly.
Also it got me to the "An error has occurred while updating the device software, Use the Emergency recovery function in the Smart Switch PC software." screen now.
(I have no code for Smart Switch recovery but I still can get into download mode using FRP Hijacker.)
Is the NAND most likely roasted and the only hope may be chipoff? Tried on different PCs with different cables.
Thanks,

Edit: I don't need a working device, decrypted dump would be enough.
Edit 2: When I skip the AP package (containing the "boot.img.lz4"), it stucks at flashing "RADIO" after a few percent.

A20e (SM-A202F) stuck in download mode - error validating footer

Hello, i hope someone can help me. My goal was to install lineageos on the A20e. So i unlocked the bootloader succesfully. Then i wanted to install TWRP. I used heimdall for flashing (with: heimdall flash --recovery twrp.img). The process ended without any errors. But since this point the phone stuck in download mode. When i restart the phone (volume down + power) the phone runs rapidly into the download mode. On the top left corner it show an error message (look at the screenshots). I tryed to flash twrp again for two or three times and one times the orange recovery - the results are the same.
I can still reach the phone via heimdall or odin. i have downloades the latest stock rom. So i hope to unbrick the phone - but until now i have no idea how to do. Please tell me, if you know some hints. You can also post if you think its hopeless and there ist no way to unbrick the phone.
Update: I have flashed the stock rom via odin succesfully. now it starts normaly. Do i want to do a next try ;-) ...
Thread can be closed...
Thank U
