Phone stuck on "Checking Connection" screen after trying to flash stock rom. - Samsung Galaxy S7 Questions and Answers

Phone stuck on "Checking Connection" screen after trying to flash stock rom.
I have tried looking at every forum my mind can handle and haven't been able to get any luck.. I'd really appreciate any help.
Device: G930A
I've been trying to fix without posting for help for a few days, I rooted my device then a day later it started acting weird (not being able to send texts on Samsung standard messaging app, then not installing apps downloaded from the play store then it went to not being able to use data on almost every app except Insta and default internet..
I don't know what else to try after attempting the stock flash to fix.. Odin says a few different errors depending on which file(s) I use.
Thank you guys and gals so much for any help you're able to give!

Boot to recovery and clear the caches
If that fails, factory reset
If that fails, flash stock

Search for the how to use odin thread. That tells you all you need. Then you just download a ROM whether its a custom ROM or a stock ROM. Open odin and flash it. Your phone will be fixed.

[Q] PLEASE HELP, Stuck in bootloop and no way out!

I have a p5113 and it is running 4.2.2 it is a friends. It turns on all the way to the homescreen for about 30 seconds. Then it reboots. I have gotten into recovery and it lets me wipe data factory reset. Then when I go to reboot it shows an error below the android and there has been no data wipe when it reboots. and reboots and reboots.........It also says NO COMMAND when booting recovery below the android. OH, I also tried flashing another stock recovery. Did not fix issue with recovery.
I have gotten into download mode and tried to cf root. Doesnt work, no recovery. Still same as above just goes to stock with no command written at bottom then error when you go to reboot it. Tried both versions of CWM and TWRP Odin files. DONT WORK. Tried to flash recovery by zip and get signature verification failure.
I figured oh, I will do what I always do to tablets try and reinstall the firmware. Which is the 4.2.2 firmware I go ahead and odin it, everything looks fine, it did take way too long like an hour and half. Passes, reboots, same operating system same data didnt change a thing! Still rebooting still recovery errors. Tried to downgrade to ICS and it passed after an hour and a half of slow odining NOTHING again same story as JB didnt change anything.
I have noticed that there is an avg in apps. I never get enough time to uninstall it. It always reboots before I can get to it. ANY HELP IS APPRECIATED.

not a brick and I am on stock if you would have read the OP you would know that. I have had a brick before the definition of a brick is a device that does not turn on. I have flashed many tabs with stock and customs. Thanks for the great advice but I am a member of XDA and I like to do things myself or with the help of others in my community. I REFUSE TO TAKE ANY ANDROID DEVICE TO CUSTOMER CARE THAT STILL TURNS ON>

i like your confidence brother but i was just helping you
also with your threads title in thought you were still having bootloop
also boot loop mainly happens when system files interfere with each other and result in instability during boot and crashes also it is not always necessary that in boot loop device would not turn on as you said earlier
i have seen boot loop on my tab even during charging animation as it was off it was due to use of flashing scripts that conflicted with each other

[Q] I've tried everything and looked everywhere

Hey everyone, I'm using a GT-P5100 (3G + Wifi) O2 UK rooted tablet and for the last month it has been broken. It started rebooting itself randomly every now and then, and then suddenly it wouldn't even boot up for 15 seconds before it would restart itself again.
I am able to get into safe mode and I can get into the boot options, but when I factory reset it does nothing, I've tried from the boot menu, from safe-mode options and even from the dial up code.
I tried to connect my tablet to my PC as a media device and format it but that didn't work either; I can't connect it as a disk then format it that way because they took out 'mass storage mode' on this firmware.
I then tried to flash a stock ROM in Odin but every time I tried it would fail until I used Odin.v1.3, but guess what, it rebooted itself and my entire tablet is still exactly the same.
(the option was on AP ram in v1.3 not AP nand I don't know if that makes a difference.)
If anyone can point me in the right direction I would appreciate it so much. I have been trying for weeks to fix this and I just don't know what to do anymore, I tried on another forum but nobody answered me.
Everyone else gets replies and I get zilch; amazing. I don't know what it is that is preventing my tablet from wiping itself but it refuses to clear the current data no matter what way I try (ROM, factory reset, computer format). If someone could just tell me what that is and what I have to do about it that would be grand.
You mention "rooted " but you don't mention what current rom or past roms that you may have flashed, you could have some sort of rom cluster [email protected]$k going on in your tab but NO one else will ever be able to help because of lack of INFO or history.
Pp.
I standard rooted it from Odin. This is my first ROM I am trying to flash. I just need to know what would prevent a tablet from rebooting itself properly. Factory reset, format and flash is not working so I must assume that rebooting is the issue here.
If you are running stock rooted rom and having issues like this the only way out is reflashing the stock firmware complete (not just a rom) and see if that fixes it before you try any other roms.
If you can get into download mode thats the fix.
Pp.
To flash it completely do I need more than an MD5 file? (I also have the partition file for my model). Another question, if the tablet is having issues with the reboot after a flash, will updating from a microSD with a zip help? Thanks for the advice.

[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.

One PlusOne recovery loop- Help needed

Hello, I need serious help with my phone.
So, after a long while of having my phone rooted, and had a case of boot loop with twrp, I decided to go back to stock os and hung up the root days. I thought i did it right by getting a stock os and flashed it, and it worked for couple months, until yesterday.
My phone keeps going into Cyanogen Recovery, I tried rebooting so many times, once it did boot up to OS, but it went back after i restarted phone or it died.
Now I can't no longer get back, I thought factory resetting will work but it didn't. (Tried both wipe cache partition and Full factory reset option from the recovery) I found unroot your phone toolkits, thinking it could help fix my problem and just unroot/ give me back to OS (I wished i found this before flashing that custom stock rom).
But the toolkit doesn't work for me, it finds adb devices, but it cant find fast boot devices, because my phone cant even go into fast boot.
I tried manual, and the option from the recovery, it keeps going back to recovery. I have an option for apply update, and then apply from ADB, that was the only way for my pc to recognize my phone from adb devices. Any clues on how to fix?

Will try, Ill respond back if anything happens!
Hmm I'm still having trouble because, I can't get into fast boot for some reason. It's keep going back to Cyanogen recovery. It has the option to reload into bootloader, but goes into cyanogen recovery again.
There is an option in dev options, uncheck the "update cyanogen recovery" and flash twrp again
