i have flashed both since this happened but cannot get it out of the bootloop need help read a few guides but i do not have twrp on the phone and i have tried just reflashing the bl to no avail

Try this if you haven't already.
Hold Volume Down and power button until device powers off...it can take up to 5 min...you have to wait.
Then go to download mode.
I'd get the OEM ROM file package for the phone and flash the entire set (4) to clean out the phone/return to fresh OEM state.

Another bricked s6- - - - Resolved

Pretty sure it's hosed but I will ask anyway.
What I have is a verizon S6 that is on AOE2, stock other than root.
What I did to cause brick: I tried flashing wifi tether mod, but flashed the AOC3 version by mistake. I flashed via flash fire but it is stuck in a boot loop.
The problem: Boot looping at verizon screen. Odin and smart switcher wont see the device in recovery/odin mode.
What I have tried: Clear cache and factory reset, No change. I tried odin but the pc does not see the phone in recovery. Same with smart switch and ADB. They do see the device during boot up prior to the reboot, about 38seconds during the verizon logo. Also they see it with the phone completely off but won't allow any changes.
Not sure what the problem ended up being, but finally got odin to pick it up. I think it was a bad copy of odin. I had odin zip on memory stick I used on each system to rule out pc as cause. Re-downloaded odin and tried again, seen it no problem. I just wanted to personally thank each of you for taking the time to help!

It's not all lost keep experimenting with Odin you should be able to recover from that. Be sure you just go straight to download mode once it boots up. I don't see why you should have problem getting it back.

So I guess I am not sure what to try. I do see the device in odin when it is booting but it loses it again when it reboots. It doesnt seem to be long enough to do anything. All I have tried is flashing AOC3 to the AP. Is there something else I can try?
Also I am not sure why, or if it is normal, but with the device completely off odin sees it. Again all I have tried is flashing the AP, and I tried smart switch in this set up as well but didnt get anywhere.
I wasn't sure what all the mod changes and if it might be kernel or something other than the OS but I am not sure how to tell or what to try if it is.
use a diff usb port/cable and flash oe2 firmware tar in AP slot. should be able to boot after that.

Tried 3 computers , few cables and every port. Seems it is something to do with it being in recovery that PCs wont see it.
Are you trying in Download Mode? Holding Power+home+down vol, then UP vol to get into Download Mode?? Tried re-installing Verizon s6 drivers and rebooting the PC? Recovery Mode won't let you re-flash with ODIN....
No reason it would be bricked from flashing a wifi tether mod.
Download Odin 3.10.6 and the Stock OE2 Tar:
http://forum.xda-developers.com/verizon-galaxy-s6/general/verizon-s6-stock-restore-files-t3096000
Reboot your phone into download mode as per DeathAngel's instructions. Odin should see the phone, flash the Tar in the AP slot. When it reboots, hold VolUp, VolDown, Home, and Power for a few seconds until it reboots again. Boot into recovery, do a factory reset.
If Odin isn't picking it up in download mode than you have a driver/cable issue.

Successfully Flashed TWRP, But Entering Original Recovery

Hi, this is not my first time flashing TWRP on this phone. And I have been successful so far.
Today I use Odin to flash TWRP, and it went through just fine (see screenshot), but when I enter the recovery mode, it says "Android system recovery <3e> LMY47X.G920FXXU2COH2 on top and I am very confused. I tried a few times and apparently I cannot enter TWRP while Odin kept telling me I have flashed it successfully...
Did you have "Auto-Reboot" ticked on Odin? On my Note 4 that used to mean the kernel would reflash the stock recovery upon booting. You need to untick this, turn the S6 off after flashing and then boot directly into recovery using power + home + vol up
Nope. On the S6 auto-reboot menas what it does. The phone gets rebooted after the flash is done.
To the OP: You used the correct file to flash? USed AP mode in ODIN?
I had same problem. I think you need to have rooted kernel through odin first. Idk, that us what i did.
Just so everyone knows how I solved this. I wiped everything and flash TWRP and it worked. I am not sure why, but that's how I got it to work.

tried to install a 6.0.1 rom and ****ed up my phone so bad.

downloaded twrp 3, was running 5.1.1 on my phone and rooted it. tried to flash a rom and got stuck in a bootloop, now I cant boot into twrp, or anything for that matter. All i can do is hold volume down and power and home and try to ODIN a new bootloader or such and it just fails. what do i do? but when I try to boot into TWRP it goes into a blueish screen with a White exclamation mark saying "An error has occurred while updating the device software. Use the Emergency recovery function in the smart switch PC software. I tried to do that but it didnt even recognize the device. At this point i dont care about the data, I just need a working device
Okay, so I attempted to unroot and flash the stock 5.0.2 software and I got a error on the download screen. It says SW REV. CHECK FAIL. DEVICE: 3. BINARY: 1.
If you have no knox install MM official then flash this kernel tar file (AP) https://drive.google.com/folderview?id=0B40ItdHKfkyQcTA5bnRPWDg0X28&usp=drive_web#list it will boot to mm 5min :good:
Btw you cann downgrade from 5.1.1 to 5.0.1 you just go up not down

Happened to me a lot of times in the past few days trying to get MM, for some weird reason flashing Unikernel always works for me (takes me to recovery screen after, then i select 'reboot now'), and all my data, apps etc are still there

will try and update. thank you. didnt work.
Okay guys so now I need a ROM to flash using ODIN. I tried to download from sammobile but the speeds are too damn slow. What I tried to flash was this file " G920TUVU1AOCG_G920TTMB1AOCG_G920TUVU1AOCG_HOME.tar.md5 " and i got the error 3 to 1.
Download Samfirm from here, XDA itself.
Run samfirm, enter model as G920F and your region code.
It will download from Samsung servers, so high speed.
Now flash using Odin the downloaded file by putting the phone in download mode, (vol down+home+power on).
How did it happen?
Did you try to flash the VOD 6.0.1 and got stuck towards the end at hidden.IMG failing the process?
If yes, then its a two minute job. Just open the 6.0.1 tar archive and look for hidden.IMG extract it anywhere and rename it from "hidden.img" to "hidden.img.tar".
Note flash this hidden.img.tar as AP in download mode, your phone should boot.

May have bricked my phone, need help

I rooted my phone a while ago in like April and for some reason it became unrooted a couple days ago for no apparent reason.
I tried Autoroot without success so then I tried TWRP without success because when I tried to boot into recovery I got a big red screen.
"****" I said but was able to boot up and decided to do a factory restore and then restore the firmware to stock with odin
This proved to be a huge mistake because after factory resetting the phone, it won't boot or go into download mode. It just shows this:
"Recovery not standard enforcing" then

vid: https://www.dropbox.com/s/4488hz6wizmhozj/VID_20160712_132305.mp4?dl=0
Anything I can do or should I just sell it for parts at this point?:
No, it is hard to brick... but you have to follow the instruction carefully... your error is the consequence of ignoring...
Take a breath and start from the beginning... first install via odin a clean original image
How do I install an image with odin if the phone won't go into download mode?

Hello,
1. first, try the normal procedure by pressing POWER+VOL DOWN. This will force your device to hard reboot. When the screen comes black press immediately POWER+VOL DOWN+HOME to get on Download Mode
2. Install Odin on your windows and download the official ROM from the SamMobile's site
3. Not that much ahead the last step. Just open the correct files inside the ROM folder with odin and flash it
| IMPORTANT |
If you really can get to Download Mode DON'T forget to flash the BT file (bootloader) inside the ROM's folder. In other words, flash every file inside that folder and your device will boot
There is no chance of getting bootloop with official firmwares. So just be patient in the very first boot

Need help!!!! G955F stuck on this screen

So I attempted to flash a combination file. I flashed G955U Combination thinking the phone was G955U. Later to find out its G955f. The phone booted up once I flashed the combination file and when I attempted to go back to stock I cannot. I've tried flashing some stick firmwares but odin gets stuck and turns the phone back on. Any help?
