My S7 edge boot loops after dirty flashing the latest version of my ROM

Hey guys,
I have had SuperStock-Rom installed on my S7 edge since its release and I've never had any problems with it... until today.
I'll be honest, when the V2.0 BETA version of the ROM (with Nougat) came out, I flashed it to my phone even though there was no Nougat bootloader and modem available for my region (W8) because I heard that it'd still work. I just had to flash the Marshmallow modem of my region in order to have signal. The only downside to this was that after every reboot, I wouldn't have any signal unless I turned Airplane Mode off and on.
Everything was fine until I was on V2.1 and I dirty flashed to V2.2 when it came out. This immediately caused a boot loop that I haven't been able to fix, no matter what I did. Here are all the things I tried doing with no success:
- Doing an Advanced wipe in TWRP and checking all the boxes except for the external SD card
- Flashing my carrier's latest stock firmware (AP, BL, CP and CSC) with Odin
- Doing the "Emergency software recovery and initialization" in Smart Switch with my serial number
- Wiping the cache and Dalvik cache and doing a factory reset before and after every process mentioned above, if they didn't work
I'd also like to add that the boot loop seems to have 3 stages: the "Samsung Galaxy S7 edge" splash screen, the Samsung logo and "Android is starting... Optimizing app 12 of 12." It sometimes freezes on the Samsung logo, but most of the time, it freezes in the midst of "Optimizing app 12 of 12." I've attached pictures of each stage to this post.
Here's my phone's information:
Model number: SM-G935W8
Carrier: Videotron
Country: Canada
I'd be extremely grateful to receive any help. Thank you.

You might be as well a victim to what I am describing here:
https://forum.xda-developers.com/s7-edge/help/s7e-suddenly-bootlooping-dying-t3528827
Although I didn't flash any custom Roms nor root, the symptoms are exactly the same as you have, including the freeze and reboot at these 3 stages.
And what else can you do except flashing the stock everything?

At least you can send your S7 edge to Samsung for repair, so don't worry!
I wish I could do the same but I unfortunately lost my warranty by just rooting my phone. :/ I guess I could try my luck with my carrier if nothing works, haha.

Samsung Galaxy J5 Prime IMEI null with no EFS backup

Hi Guys
This is my first post on xda even after using these forums for years. But today I cant find a solution on here or anywhere for that fact, and was literally hoping that I've missed something somewhere.
So to start. I have a Samsung Galaxy J5 Prime (SM-G570F). The other day I was flashing a custom rom when something went wrong during the flashing process and left me with a bricked device. Now I did do a full backup before flashing as I've learned the hard way how important this is. During the flashing it also asked me for a full wipe and to backup the EFS. Even though I did do all the backups and wiped everything< I've ticked both boxes and proceeded with the installation. Everything seemed fine but on 99.9% it froze. Not wanting to do anything I left it until it rebooted the phone by itself, where I was greeted with the download/flash screen. Didn't even give the warning about installing custom software and asked to continue. It just booted straight to the download screen. Tried getting back into recovery only to be greeted with download screen. No matter what I did it just kept booting into download mode. So I then re-flashed TWRP. Getting into the recovery I was able to mount EFS, System, Data, etc. Bu all showed 0mb of 0mb available. I then went to restore everything only to find that the SD Card was also wiped by the process. Thinking that maybe the recovery isn't reading everything correctly, I found the SD Card empty in windows also. No call me names or whatever, (I know my own stupidity) but I never backed up my backups on my PC. So I just proceeded flashing stock firmware as to start from scratch. Everything went as planned until the device got reset by odin. I was greeted with a screen saying "installing system update", but as soon as it reach 32% it changes to "erasing" and then "error" with the "DRK Missing" error. Then it boots to recovery where an error message is saying "unable to mount: EFS (Device or Recourse busy). I cleared cache and did a factory reset and it booted the system (Though mount error still appears in recovery even in custom TWRP/CWM recoveries also). Now I have a 00000..... IMEI number and no network connection. I've spent the last week on the web trying to find a solution with no luck. I'm tired AF because I didn't sleep trying to solve this. I tried flashing stock and custom roms, recovery's, boot-loaders, modems. Tried different software's like Samsung Tool, IMEI repair tool, Strings of adb commands, xposed modules, apps, terminals, etc. I even flashed factory binaries with no luck as to how to change it back.
So in short.
My EFS got wiped.
I lost my IMEI.
I don't have any backups.
Been awake for a week searching for solutions with no luck.
So please if anyone knows of a way to change the IMEI, please help me. I know It's illegal to change IMEI (though not in my country). But I down't want to change it for all the wrong reasons. I just want to change it back to the original found on the back of the phone and on the box. This can't do any harm can it? Please I just want my phone back please!

If this problem is still open, then on Your Phone box is writen imei, or take battery out and under serial number there will be your imei, root your device and use IMEI changer grant root access and type your imei in it, after that reboot and your imei should pop up! I had same issue and this steps made my day! THIS WORKS ONLY ON YOUR IMEI, YOU CAN'T CRACK, STEAL IMEI By this method, don't believe those Dumb ****'s from YouTube!

May I help You!

N910F Stock firmware corrupted.

My note 4, randomly crashed, running completely stock.
Began bootlooping and hasn't stopped.
Have downloaded firmwares from Samsung-Firmware . org, as SamMobile will literally not allow me to download anything for free??
No firmware has worked on the device, Have tried numerous PDA versions as I am unsure which the phone originally is.
The first firmware gave the error "dm-verity verification failed" in the recovery menu.
Have wiped cache and data.
Note: This is actually the second N910F which had corrupted itself and stopped working.
Help! :angel:

Do you want to recover some data from it?
If Not than you can try factory reset from Recovery menu.
Other than that it might be memory corrupted or your battery.
Try to change the battery.

New battery: Allowed the phone to boot past the first "Samsung Note 4" screen to : "Samsung" logo, but the phone made a loud beep/screech.

If you want to reflash the Stock ROM search for a version on https://updato.com
I just reflashed mine (g910f) even twice as I had an Infini-Boot, too. After cleaning Dalvik/Cache and formatting data, taking out the battery, after some time it suddenly displayed that it's going to setup apps and it works since then ...
So maybe just be patient.

to get the latest stock rom for your device, free and fast
look what you have to do:
download this (windows ) application and install it on your windows pc.
This is the aplication that will allow you to search and download the latest stock rom for your phone.
It connect to Samsung servers and in very little time you will have a new stock rom on your pc.
choose samfirm 3.06
extract it on a folder on your PC and run samfirm.exe
in the opening menu type
SM-N910F(or T/V/W etc your phones model)
REGION..... xxx (your region code)
these 2 you can find in a sticker under your battery if you open the phone and take off the battery
tick '' BINARY NATURE''
(If you dont tick BINARY...'' you will get the whole stock rom in one file xxxx.tar.md5 to flash it in the oding using the AP tab)
CHECK UPDATES>DOWNLOAD
THIS WAY YOU WILL GET THE LATEST STOCK ROM FOR YOUR PHONE/REGION
Binary nature means the rom split in 4 files
1. BL- bootloader
2.AP - rom
3. CP - modem
4. CSC - Customer support code(region/country)
This is what a stock rom is consist of
this kind of rom is also called REPAIR ROM, because you can use it to repair your phone.
If you look in odin you will find exactly these 4 entries.
So you can put each in the appropriate box and flash them all and so have a stock rom.
push start
Wait until rom flashes and phone reboots.
Hopefully it will solve your problem and everything will go as we all wish to.
BUT, from what you are describing, i am afraid for 2 things:
1. Your battery is almost dead, thats the good scenario .
With 20 $ you will solve it.
So new battery, new rom> problem solved, or
2. You are starting to have the emmc failure on your phone.
Thats a tough one.
Lets hope its not the case.
Just in case

SM T595 NEED HELP LOOP MODE FLASHED

Hi I'm not a tech savy person but I can follow instructions lol.
My tab locked up on me and I've searched for days and still have not been able to fix.
Ok details are
Samsung smt595
I've uploaded pics of system info
I downloaded odin 3.14.1
Samsung drivers 1.7.43.0
AnD T595DXU4CTJ2 -
T595OLM4CTJ2-TEL
firmware.
Flashed with odin
PASS
but does the same boot loop
I've tried clearing data reset and so on but nothing is working.
I'm in australia and the tab was set to telstra mobile by default.
Any help would be great 8
I will have missed info needed for sure so please let me know what else you need.

Go to recovery mode
Wipe Data
Go to fastboot mode

I followed this with Stock Android 10 , but the device was still in loop with these symptoms:
- resets after 2 Minutes just showing "Samsung" writing on screen
- duplicate entry of "recovery"
- odin showed no error, I tried home_csc as well as csc
I switched to Android 9 image and now I could revive the tablet, I hab to go through the FRP after Start, but thats ok.
Maybe there's some issues with the new image (also the duplicate recovery seems to be caused by V10)....
After applying 3 OTA Updates the tablet is running like a charm again.

Try Changing the firmware . You can Flash lower Android version and then can update to Latest Android via OTA updates !
