Are you sure you cannot get into download mode? Hole power til you see the LG logo twice, then release so it powes off completely... Then hold only Volume up and plug the phone into your computer while holding it.

What did you do or think you did to cause this? I would be easier to help if we knew what you were doing when this happened.

I had the same problem. Spent nearly 10 hours trying to figure it all out but never made any progress. I sent it to LG though and they are working on fixing it up right now.

i got an update after i installed it it didnt boot to system , went to recovery and after i restart it this happened . .
try plugging it in and use the LG software...I never done it myself but if you search i think there is a way you can fix it using LG software.

I am not sure if you this will help 100% but what I did was installed the recovery in my phone then I updated my phone. Which made my phone go in recovery and if I restarted it gets stuck in recovery. I wasn't able to get in download mode as well.
If you can get in "recovery" then you can use this fix
to get in recovery hold the vol- and power button until your phone vibrate and you are in recovery.
then execute these commands through adb shell
http://forum.xda-developers.com/showthread.php?t=2451696
Edit--- after executing the commands flash the stock rom--- using LG flashing kit. Search the xda and you will be able to find a thread that details how to do it. yes you will be able to get in download mode, i got there in 2 tries.

What kind of update caused this? You mentioned you got an update and then it was stuck dead.
Rooted/Custom Rom?
I was about to root my device and came to look at some instructions, this thread scared me...

Sorry, can't read the link, but by recovery, you mean TWRP, right?
So basically, after rooting we can still do an OTA update, and it's still safe, right? But once we installed TWRP, we should not do any kind of OTA updates?
For TWRP, is this method good enough:
http://www.youtube.com/watch?v=nTJI9ThY0mk
To Root, I will use this method:
http://www.youtube.com/watch?v=Y45SXPRb31o#t=149
Sorry if I am steering topic off-course but I just wanted to make sure others don't do the same mistakes and end up in same situation.
Your suggestion of not doing OTA update is really valuable, so I wanted to build on that.

The easiest and the way that really worked for me was to root it using "Vroot" http://www.mgyun.com/
but you should check which phone you have and which OTA version you have. As far as I know 11g and 11c for korean variant can only have cwm i am not sure if that is true for other phones as well. But be sure to check it. TWRP only works for 10x versions (where x is any alphabets) still dig deeper, I might be wrong.
But you should never update your phone after recovery.
and backup your IMEI number ... the thread i posted earlier try using google translate and download the apk to backup your IMEI by Hoang.

Did you try and flashed rom again ( odin) ?? another option would be to flash (odin) a custom recovery see if it let you enter it and do a factory reset ..only problem is it will trigger your knox bit to 1..
@lloop: Are you completely stock, or did you attempt to install a custom recovery? The behavior you describe is identical to the behavior witness by myself and others when trying to install TWRP 2.8.5.0 on the S4.
One other thing that might help here. On occasion I've had the device get stuck in recovery. Going into download mode, cancelling download mode, and then holding down the buttons to go into recovery often works.

Recently just got the s8 and tried to flash and root to get the batman rom. My attempt was a huge failure. I failed the instructions and even had a friend you had already done this process check if I did anything wrong. Once in Odin and flashed with Twrp my s8 did not boot up to the os homepage nor was it in recovery mode. It was a black screen saying something along the lines of "verification reject" and the only option I got was to reset the phone. Reset the phone and tried to flash it again, same thing happened.
At this point I just wanted to use my s8 stock everything so I tried to go back into recovery mode but now I'm stuck in a boot up loop and I can only go into download mode. I tried flashing it with all stock everything except now one in Odin the process fails. Odin is still able to pick up my phone but once you hit start it will say "fail"
I can't turn off the device I just pretty much left it to die so it's kind of "turned off" but I've tried virtually everything I could think of. Not sure if there is anything else I could do or if this s8 is just literally a brick now. Any help would be gladly appreciated!

Did you follow the steps exactly as it says here?
https://forum.xda-developers.com/ga...pment/recovery-twrp-galaxy-s8-exynos-t3595102
eg: when you press start in Odin to flash TWRP hold recovery button combo?
I would suggest starting again, go to download mode and start and read the instructions a few times step by step.
Or flash stock firmware and then start again. If you get an error in Odin post it here for help.
Hello

I downloaded the BL from BatMan Rom so there is no need to load the full Firmware

I'm able to get into TWRP with the method you just showed me so thank you!!
I keep running into problems every time I move a step forward. Now when I move the batman rom file to the storage it says "failed" or file "corrupted" am I still doing something wrong?
even with TWRP, Magisk and no-verity installed my phone still can not boot up into the phone's OS I'm still stuck with a boot loop.
I've tried to wipe everything already and start over and still I'm in the loop

Sry for late answer :/
Have you tried to dl BatManRom again?
Maybe your dl wasn't successful
Try again, should work
I also installed BatManRom ?
Best Rom out there
Install BL and CP from BatManRom via Odin, then boot in TWRP
Advanced wipe all except external and then flash Rom
Choose your Settings, no need to install BL and CP again
after install, Reboot, wait for around 10 mins, then Setup System and all should work fine ?
Cheers

You need the edl firehose and XML files and the software for recovering from a brick like that.
And frp bypass is not an allowed subject here because people who ask tend to have a device that is likely stolen

Hello everyone,
I have problem with my s7, after trying to flash stock several times using odin, I am always getting s7 logo, and than blue screen with Erasing... , than it would restart with same pattern two or tree times and than shut down. I can only go in download mode, cant boot into recovery.
My phone is SM-G930F. I am pretty sure that I downloaded correct firmware. Maybe I did mess up something, any help is welcome.
Thanks in advance.:fingers-crossed:

I'm having the same problem. Using the binary U5 "combination" file, I was able to access the system and enable OEM unlocking, so I could install TWRP and then a Custom ROM. But that's it, I can't use ROM Stock anymore, my phone only works if it's in a Custom ROM. I wanted to solve the problem so I could use Stock again. Bottom line: In ROM Stock, the phone is locked under the name SAMSUNG GALAXY S7 EDGE, enters recovery and appears "ERASING" then erases and repeats everything again, never starting the system or having access to Recovery.
Sorry for the bad english, I used translate ...
