G920F keeps bootlooping in a strange manner - Galaxy S6 Q&A, Help & Troubleshooting

Hello everyone, I've got a S6 G920F, that I tried to do everything to. Here's the problem and what I did:
First off the phone never turned on unless I put it in the charger and it would display the "emergency mode" screen. I switched to download mode while its attached to the computer, tried to flash stock firmware with no luck, until I found a PIT file that I flashed via odin and revived the phone that it got me the "Samsung" logo. But still it would turn off. I did efs repair and phone stopped turning off but still was stuck on samsung logo. I then came across this "choimobile" 4 file firmware and flashed only BL and AP(as they said) and phone finally turned on, started optimizing apps, finished and entered the system, I went to check if IMEI is intact from settings, and it suddenly rebooted, to system again, except this time for few seconds and reboot, then it got stuck on bootloop on the "samsung". I've been stuck here with nothing left to do.
Here are the links I used:

Would appreciate any help thanks in advance.
P.S. I did wipe data and cache using recovery numerous times

[Q] Phone bricked and stuck on recovery.img in Odin HELP

hello,
I tried flashing an ICS ROM onto my Samsung Galaxy S2 Skyrocket (i727 AT&T) using Odin.
It was stuck at recovery.img. I unplugged my phone after a while, and then it wouldn't turn on. I would hold the power button, and then the Samsung logo would appear for a second, screen would go black for a second or two, and then the Samsung logo would come on again for about a second. Then the screen goes black.
I got into recovery mode, and wiped my data 3 times. I also wiped the cache. Then I tried rebooting the system, but the phone wouldn't turn on.
I took out the battery several times, and even tried turning the phone on with a different battery, once again to no avail.
Now I'm trying to flash the ROM on again, but it's stuck at recovery.img again.
PLEASE HELP. How do I get my phone back to normal/successfully get the ICS ROM on it?
I'm a noob at this.

Install this rom and you should be able to boot
Breaking News: ICS for Skyrocket Leaks, We've Got The Link (AT&T)
XblackdemonX,
That's the exact ROM I tried to flash. It's stuck at recovery.img. I unplugged and my phone wont boot.
However, that link mentions Heimdall files, what are those?

Galaxy s6 G920v stuck in bootloop, have tried everything

Hi guys, so recently I bought a Galaxy S6 Verizon off of eBay. I got it for fairly cheap because it was stuck in a boot loop. I usually have no problem fixing stuff like this, but this time is different. So the first thing I tried when I got the phone was to do a reset and cache wipe from recovery. I rebooted the phone and it showed a screen that said "Android is starting, optimizing app 9 out of 31." when it got to 21 the phone rebooted and went back to 9. It did this several times before I attempted to wipe/reset again. I then downloaded the tar file G920VVRU4CPH1 and flashed it in Odin. I did a manual reset before the phone booted, and it is doing the same thing again. reboots to a green screen where it tries to optimize apps, stays there for about 20 seconds, and reboots over and over again in the same cycle. I have tried all other stock marshmallow roms that i can find, Odin won't flash older ones, (assuming its not letting me downgrade). Also another weird thing, every time I flash, the blue update screen goes to 32%, stops, erases, and reboots. Phone is on 6.0.1 version MMB29K.G920VVRU4CPH1 as seen in recovery. Any help would be gladly appreciated. Thank you!
I am having a similar problem with loading new rom. The farthest it gets is 32%. Sometimes it doesn't get even that far.
I ended up just buying a trashed s6 and swapping the motherboards. Only way I could fix it

[Completed] LG G4 h811 unable to factory reset or enter download mode.

Hey guys,
Sorry if the answer to this found somewhere else, tried searching but foud nothing for my situation.
My buddy, who is a super basic user and was not attempting to do anything with his phone, has a G4 that suddenly stopped working and went into a boot loop.
We tried factory resetting it and it got about half way through the apps before stopping, going back into a boot loop and was unable to get back to the same point in the factory reset.
I tried flashing the ROM using LGUP to H811-20o and it said that it went successfully on LGUP as well as the phone itself, but after it rebooted it went back into a boot loop.
Now the boot loop goes faster but is still looping and we cannot get back into download mode to try again or potentially try a different ROM. It goes to the first screen of download mode with the 5 blue dots but doesn't get past that, I've removed the battery waited for a while in between attempts and still nothing.
We can get to the factory reset screen and click yes, it will then go to the green android guy with his cog wheels exposed but then immediately goes back into a boot loop.
Any help is appreciated, even if its just a confirmation of being SOL.

Help, after flash TWRP and do factory reset instructions in Chinese

Ok I will admit it, I screwed up royally this time. My SM-N9150 (Hong Kong version) was slowing down and draining the battery fast. I could not get the downloader of a new stock ROM to work in Sammobile (tried multiple times, with adblock off but no go) and so I bit the bullet and used Kies to upgrade to Marshmallow. Of course this lost root but I figured I could just re-root (I had rooted using Odin with my old phone, but this one I had rooted using KingoRoot). However, none of the 1-click systems like KingoRoot worked, and neither did Chainfire via Odin (which caused problems on its own). So I flashed the latest CWM via ODIN. It said pass, so I went into recovery, did a backup, then did factory reset, installed SuperSu, wiped the caches and rebooted.
I kept getting weird errors where it would not let me boot into recovery or boot at all. so I thought that maybe CWM was not a good choice. I tried the newest version of TWRP but that gave me the "recovery is not seandroid enforcing" error. So I went back the CWM and tried wiping again.
After a very long Samsung logo bootloop, it eventually showed gearings turning but with instructions in Chinese. It then showed the logo again for long time and then showed something that had only 1 English word "system" and the rest in Chinese. There seemed to be 2 choices at the bottom of the dialog box. When I chose the one of the right, the phone showed a grey progress bar with Chinese letters above, but then went back into a bootloop; when I chose the one on the left, the phone turned off for a long time then restarted but again seems to be stuck at the Samsung logo screen before returning to the message with the word "system".
After it going into a bootloop that lasted over 1 hour, I pulled the battery and then went into recovery and tried restoring the backup I had made at the start. That just left me in the endless Samsung logo bootloop. I left it plugged in overnight hoping it would do something but nada. At one pint I did get a message "unfortunately, the system UI has stopped working" but screen was unresponsive to press OK, and it just went back into the bootloop.
I realize I did not do anything to unlock the bootloader. Would using KIES have locked the bootloader again? Could this be my problem, and if so, how do I fix it?

Bootloop

Hey all....I'm calling on the experts! I have a friend of mine's s8+ Sm-955U from Verizon. She woke up one morning and it was boot looping. I've tried using ODIN, reflashing the original rom, wiped cache, did a factory reset, and even used the pit file and repartition in ODIN to try to restore it. All it does is get stuck at the s8+ logo screen, goes black and you can feel a tiny vibration when it goes to black. It usually just sits there, sometimes it will just reboot over and over. I've done everything I know. Is it possible that the NAND would be bad? Or what wears out if it's hardware related? It boots just fine in recovery mode or download mode and ODIN always shows success when flashing. Anyone know of anything else to do?
the phone is overheating!!!! get an icepack and hold it to the back of the phone while loading or put it directly in front of the air conditioner!!!! my phone does the all the time
