Hello Guys,
You are my last hope. I’m trying to fix a S7 which fall down but worked fine after this happened. Then Samsung made an auto update and after this the phone doesn’t start anymore.
I tried several things. First I flashed a stock firmware via Odin without any success. Then I saw that the FRP lock was active and "shortly" unlocked it via the bypass method from user tungkick. After that I installed TWRP and tried out several firmware’s and custom roms.
The only minimal success I had, was with the Hydra Rom which I flashed exactly afterwards the manual. After trying several time the devices started until the point "android starting....apps get opened....
After 45 minutes with no change I abort the process and shut down the device.
I tried to flash it at beginning with the back cover and after it without to check if there is any loose cable (what I haven’t done up to now).
I also noticed, that the phone disturb my wireless keyboard while stuck in boot. After put away the phone from computer the keyboard woks fine again. Maybe this info is also important.
I hope you can help and I ready to give any information you need.
Best,
Kilian
Factory reset from recovery?
Yes, also tried several times. No change

Where to start...
First, as a disclaimer, I may use language or terms that sound noobish. I have rooted and run custom ROMs on several devices in the past, however generally when I get a ROM I like I stick with it, so I'm not constantly tinkering. I've done my best to search and find solutions so please go easy on me.
17 days ago I was running stock 4.3 on my SGNII when the battery died. Upon charging I found I was stuck in bootloop and had a bad /efs mount. I searched and searched and spent around 15 hours trying this and that but to no avail. I finally threw my hands in the air and got ahold of Josh at mobiletechvideos and he was able to fix the efs mount issue. However, he left me in factory mode which required me to root to get out of, and once I did this I was unable to activate data on my carrier (Ting). I was so happy to have my phone "back" though that I used it like this for 4 or 5 days. I could get on wifi and I could call and send text messages. I had been off the grid so this felt like something I'd fix fully later.
Well I kept reading and found "fix" after "fix", flashed this and that and still no dice. FINALLY, last night, I found this thread: http://forum.xda-developers.com/showthread.php?t=2086769 which helped immensely. I was able to get TWRP flashed by unchecking the "auto-reboot" option in Odin and pulling the battery after the update took, and via TWRP I was able to install the ROM. I booted up, the device activated, I was running 4.1.2, I made and received some calls, the birds were chirping, the air was sweet...
I had struggled for so long and I had finally achieved success! Then, for seemingly no reason at all, I accepted an OTA update which bricked my Note2. Devastation.
The current state of things...
* Cannot get past the initial "Samsung Galaxy Note 2" screen
* Cannot boot into recovery
* I CAN get into dl mode,
* but, I CANNOT successfully flash anything. TWRP will flash like it took, but upon reboot I'm not able to boot into it. I'm also able to flash a ROM but it fails when it gets to sbin, and upon rebooting I'm greeted by the screen "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
When I try to use Kies it doesn't find the device. I've installed all of the most recent drivers and I'm running Kies as administrator. I select Tools > Emergency Firmware Recovery, THEN connect my device as instructed.
I'm at the apex of frustration. I beg thee to help!!
Hello everyone,
My Galaxy S6 G920I has started shutting down repetitively. I was on stock and not rooted. After it happened a few times I decided to hard reset it and delete cache but it would get stuck on starting apps screen etc. After many attempts the phone finally started the user's guide for logging in etc. I was getting crash errors for settings and other things. It finally went in only to start shutting down again. Seeing how the apps were crashing I thought that there might be an issue with the stock ROM so I decided to flash a new one. I was having trouble finding my specific so I went for another one found here. I couldn't flash it with ODIN because it was on a zip format so I flashed TWRP on the phone.
The error recovery is not seandroid enforcing is now showing on different versions of twrp (2.8, 3.0).
I can't flash any ROM now and the one found in the device keeps shutting it down.
I don't believe it is a hardware issue as the phone stays on without issues on download mode. Any help on what steps to follow next would be highly appreciated.

Update it via smart switch it will turn on after that for sure. Or download the latest firmware via samfirm and flash it with Odin.
Thanks!

I tried flashing the stock rom with ODIN and the phone successfully boots now. So a big thanks for that as it is progress. BUT the issue I was orginally having persists: The device keeps turning off 10-20 seconds after booting. Do you have any idea why that might be?
Sometimes it will freeze first and then turn off but never stay on for longer.
I have tried Safe Mode and turning all connectivity related modules off.

This is weird don't know what the problem might be. Still I suggest you to flash it with smart switch once and see.
I've got a Vodafone UK version SM-G920F that has recently started to freeze, crash and reboot constantly.
I managed to back up my data and perform a factory reset from the Setting page, but it crashed 10+ times during the install process (would freeze at various different stages, either rebooting on its own, or requiring a Vol Down+Power reset)
I'm now on a fresh install, but it's still rebooting constantly. I managed to use it like normal for an hour today, but right now it's just rebooted 3 times and won't even get past the Samsung loading screen without several Vol Down+Power resets.
What other options do I have? And is anyone aware of a known hardware issue that could cause this?
I was considering flashing a different ROM, but I'm scared it would reboot during the process and corrupt something...

Maybe a battery issue?
a friend just gave me his very same model phone with the very same issues.. if I find out anything I'll tell you here, or if you solve it first please write down what you did.
Thanks Vibbuz.
I've been trying to download a stock firmware to flash via Odin, but download speeds from Updato are really bad.
So I managed to flash a firmware after installing Odin on a Windows laptop (painful trying to get it to work on my Mac)
Firmware installed OK, but after boot I was getting a constant "com.sec.epdg" pop-up box that wouldn't let me use the phone at all. Not sure if that's due to the tsar3000 firmware?
Wiped the cache and did a factory reset after booting into recovery, and now it's stuck in a boot-loop again (95% of the time it hangs at the Samsung logo animation)
Just tried using SamFirm v0.3.6 to find the correct file. Downloaded a 4gb file, but several attempts to extract only gives BL, CP, CSC files but no AP (throws up an Unknown Error during process).
So still stumped!
Yet another update. Left Updato running overnight and downloaded a firmware.
Flashed it with Odin, claims to have succeeded but phone then reboots and hangs at "Erasing" stage (Android logo is spinning, then stops)
I'm starting to think it's pretty broken...
I've been having this exact same issue since June. If your phone happens to boot try activating power saving mode (to reduce cpu speed) as soon as possible.
It seems that doing that diminished the frequency in which my phone rebooted. If it also helps you it might be a faulty battery that can't provide enough voltage. (I'm not 100% sure on this part though, just thought of it because of the apple batteries drama)
Please post your results! Looks like a lot of people are affected by this and it would be great if we could find the cause of the problem.
I just read your thread actually! Sounds very similar to mine.
I've got nowhere. I don't think it's hard-bricked as I can still access Odin mode on the phone, and sometimes boots to Recovery, but it freezes and various different points and is currently unusable (either freezes at Samsung logo, "Erasing" part after installing firmware, or once it started to run though new device setup then froze).
Went ahead and bought an S8, but still want to fix the S6!

Hi I have same Problem I send the my s6 for repairmen that Saied me this problem related to mobile Hard drive.
I didn't believe it and try some official rom and a rom from Philippine GLB solve my problem for 3 M/o but now developed as same problem whitout any successful rom installation.
I think this problem from incompatibility google play store version to my rom. please flash a custom rom without google apps and immediately after installation turned off data and Wi-Fi internet after 2 day whit sim card whit out any change in setting can use it.
Hello,
anyone found some kind of solution? Happened to me also - freezing, restarts and then my S6 stopped working.. Sometimes I can boot to recovery menu, sometimes it boots up to android (and then freezes again), but the chances are almost non existing. Service man told me the same thing as @ghasemzm - eMMC failure. Yes, it is completely possible, but i don't wanna believe it, because they only tried to reflash the rom. I've made some "google research" and found that there were some issues in power IC on S6/S6E. Could this be related to it?

Will test the theory and let the group know.
So i have installed philipines latest update 6.0.1 i think with PIT file provided on Sammobile.
I have tested it for a day with normal ussage like i set up every other phone and it still continued restarting.
Figured out let me test with no google account signed in and the phone is working perfectly. For a full day.
So i dont know what the problem is but i will try again with google account tomorrow for a day see what happens.
After that will install 7.0.1 uk update with PIT file for it and test with that.
I have the same problem and I am quite sure that it is the mobile hard drive.
I tried to use F2FS but didn't find a working rom for that.
Samsung refused repair because of root.... Never Samsung again!
same issues here - any solutions found? My best guess is hardware fault...
I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.
I have also tried turning the phone off with the Recovery screen shut down option (since I can't seem to be able to turn it off with the power button right now), wait a few minutes, then turn it back on. Nothing changed.
Please, does anyone have any insight into this? What else could I possibly try, or what could I be doing wrong? I really don't want to send it to repair yet again in such a short time.
Many thanks in advance.

You need to clear the cache after flashing to get out of the boot loop.
Use the download key combo to restart. As soon as the screen goes black move to Volume up+home+power.
In the recovery menu choose clear/ Wipe cache, then choose reboot.
I apologize for not updating this thread before when it was still recent. The fact is that I didn't manage to fix my phone; clearing the cache after flashing did nothing to stop the loop.
I ended up taking the phone to the people who have fixed it in the past and after more than one month, they gave up. So I got my phone back and I want to try to give it another go before I just sell it for parts.
Unfortunately, my phone has come back even worse. Now it has no Recovery Menu to speak of, at least none that I can access; after a few seconds of the blue text on the top saying that it's entering recovery mode, it then proceeds to a blue screen saying: "Security Error: This phone has been flashed with unauthorized software and is locked.". I can still access Download Mode.
I have attempted flashing a few firmwares that I believe should have worked with my SM-G930U. Odin listed the attempts as "pass" and, after restarting and going back to the Download screen, it says the binary is Official. However, after trying to restart the phone normally, it starts displaying the blue screen again, and then, after going to Download mode, the binary is reverted to "Custom".
I believe right now the order of the day is to get the recovery menu to work again so I can do all the cache cleaning that seems to be required after flashing firmware. Any ideas at all on how I should proceed? Is there something specific I should download to fix the recovery menu?
How many files are you flashing in Odin, is it just 1 file in the AP slot, or 4 files: AP, BL, etc.? Also, is your phone rooted?

Never rooted, was using the phone legit before it froze and entered boot loop. I flashed all 4 files, multiple times.
Someone tried fixing my phone a few days after I replied to this thread and some progress seems to have been made, but now the phone cannot get past a black screen with a "SBL Error! rdx_init!" in red text, and "upload mode" in yellow text. Still cannot access Recovery Mode, but Download Mode still works.
I did a little Googling on rdx_init errors and it seems I need a firmware dump from another G930U or something like that...any ideas on how I can proceed?
Flash it with Eng Boot in all slots using patched Odin. Reboot to recovery and wipe it. Reboot system. Then root it with advanced adb root. Links for all of this are here in xda. Enjoy

Sorry, I'm not an expert at this by any means, I'm not sure what files to get. So far I've found and downloaded the following:
S7_Oreo_Nougat_Adb_Advanced_Root_V10
S7_Oreo_Nougat_Adb_Advanced_Root_V12
S7_Oreo_Su_Binary_Only_ADB_Root
But I had no luck flashing any of these cause my binary is 10. Is there any more help you can provide me? I really don't know how to proceed

I thought I had one in my phone, but I don't. If you look at the thread where you downloaded the Root_V12, you will see it. It's near the end of the thread somewhere.
Okay. I was messing around with my firmware which I've done in the past. I've had a few problems then due to my phone model being obscure (Samsung Galaxy S6: SM-S906L). I've always had a copy of the firmware saved to my computer in the event of a bootloop or a similar issue, I figured I could just flash it with Odin to fix it. I have also done this in the past. After accidently wiping my phone, I went to re-install Magisk, but noticed my phone trying to push an update. I let it go through without much though and after it finished saw it didn't change much. I carried on with re-installing Magisk when I figured I might as well fix some problems I had with booting the phone (I would have to boot it into download mode then recovery to get it out of a bootloop each time I turned it off). I carried on with flashing my saved firmware to fix the problem. Everything flashed fine except the bootloader. It's come to my understanding now that because I let the update carry through with my phone, my saved firmware is no longer compatiable dispite the fact that it didn't change my android version. So now I have a bootloader installed that is meant for a higher update without my known ability to downgrade. Due to the obscurity of my phone model, I can't find anything to bring my firmware up to what my bootloader is at. So now my phone is stuck in a bootloop with the ability to access download mode, but recovery mode simply gives me a "recovery is not seandroid enforcing" error. I would greatly appreciate it if someone has any advise they could give me.
