Serious Bootloop Question - Samsung Galaxy S7 Questions and Answers

My phone (930A) seems to be stuck in a major bootloop or might even be bricked. Here's a list of issues I am having:
Get's to the AT&T screen, makes AT&T sound then freezes.
In recovery booting mode it says: DM-Verity Verification Failed
Factory Reset and wiping the cache does nothing
Bootloader itself freezes and doesnt get recognized by odin
Any help on this would be greatly appreciated

I am stuck on verizon screen after doing nothing

It seems my phone started saying that random general apps were crashing and then i tried to reboot thinking this would solve the problem now my phone wont boot past the verizon screen. Am i really going to have to flash stock to repair this? or is there another way?
Nevermind I wiped and reset to factory then rebooted to safe mode and now it works, but I've lost root and all my files/apps.

[SOLVED] Constant reboot, need urgent help!

Hey guys,
I have encountered a serious problem on my device. Today I rebooted my phone once and it has just stuck on the samsung logo. Then the phone began to reboot without ending....It could not just start. With the help of TWRP I have made a full wipe and tried to reinstall my actual firmware Superman 1.10.5, but I always stuck at 25%, the phone did not respond to any actions. I even tried to flash the stock 4-file firmware with Odin, but it did not help, the phone constantly reboots. Sometimes it manages to boot to the stage where the sign "installation of applications" appears, but a while later it stucks again and reboots. Please, help me to solve the issue, because I am begininng to think that it would be unpossible to recover the phone. I am only able to enter the download mode or recovery, anything else does not work.
Thanks....

Really sad to hear that story mate. First things first, I assume your BL version is matching with the firmware your flashing right. And when you go to TWRP, can you see /system and /data partition from the mount menu? If not, you have to perform a factory reset. I had issue like that with my Galaxy S7 and usually factory reset(not wiping) helped me with that situation. Since your system can boot up, but crashes after awhile, I do suspect that some of your partition might be corrupted(at least its what happened to me). So trying factory reset can be a good bet for you.
And... I think you have to provide more information with which variant you are using, and your BL version, TWRP version too, solve the problem quicker. Hope this information helps.

Yep, you are right, BL versions always matched firmwares. I tried to wipe the phone with TWRP 3.0.2.3 and also to make a factory reset with the stock recovery. The stock firmware, which I tried to flash, was G930FXXU1BPH6_G930FOXE1BPH1_SER consisting of 4 files including BL,AP,CP and CSC. After 3rd or 4th flash of the same stock firmware the phone suddenly became alive and began to boot. Wu-huuu:silly: I was happy as a child. After having successfully launched the stock rom I have again flashed TWRP 3.0.2.3, went to "wipe" option and formatted data. Then I have installed a Superman Rom 1.12 and everything went the right way. I don't understand only one thing: why after having wiped the phone several times and having reseted it through the stock as well as TWRP recovery it didn't want to boot.
As you said, I suppose that the one of partitions was corrupted. Oh damn, I thought that I won't be able to resuscitate this phone.
I have flashed about 20 phones during my life, but I have never ever encountered such serious problems.

Samsung Galaxy S6 randomly restarting / gets stucked

Hello guys!
I am encountering an issue with my Samsung Galaxy S6 G920I. The phone suddenly started to restart on its own every 30 seconds or so. After some restarts the phone started to get completely stuck in a randomly time matter, and the only way to take it out of there is by doing a hard reset (volume down + power buttons).
I tried everything. Did wipe cache and factory reset in recovery mode, flashed a new stock ROM with Odin several times but it is still doing that.
The stuck issue also happens on screens like "installing update" or "erasing", after doing the ROM flash with Odin.
Any thoughts?

Try device initialization using SamsungSmart Switch. it Should solve the problem. But that method wipes entire internal storage. So backup before you do anything,
Device initialization is something like resetting it to factory setting by clean install of the firmware.
Hi, could you fix it ? The exact same thing happened to me. I was using stock firmware (I never rooted it or anything) and it suddenly began to reboot by itself. It can be stuck in a bootloop for 2 straight days and then suddenly boot normally and use it for a couple hours until it starts bootlooping again. After a month of having this issues I decided to flash stock 7.0 firmware with ODIN and also with Smart Switch but after succesfully applying the update the phone reboots with the "installing system update" screen and then it gets to 32% and it says "erasing" after which it starts the bootloop once again. I'm stuck with a $500 paperweight. I'm afraid it could be something with the motherboard any help is greatly appreciated!

Problem fixing Stuck on logo screen

Hello i have a problem with my phone that suddenly i wake up and my phone was stuck at logo/loading screen i restarted and still stuck i tried most stuff on the internet to fix it and still no luck.
I ask for someone to help me with this problem since i need my phone and i can't find the stock rom for this phone maybe because i'm searching for the wrong stuff i don't know.
Things i tried:
Wipe/clean cache data etc- still same
Flash recovery.img through fastboot using "fastboot flash recovery recovery.img" -- still no luck and got error "recovery doesn't allow flash"
Downloaded some rom for this phone after searching the internet with this number that apparently it's the serial number that i get on "Android system recovery" 857413_v2.8_20150130 -- still nothing to help because after trying to install through adb i get error "installation aborted"
So if someone could help me out or tell me if i'm doing something wrong please tell me.
Thanks in advance.
