probably you flash the wrong firmware and then got that error, try reflash the right one and see..
if not search here at forum a post made about fix bootloop, they have kernel avaiavle to download, just put the phone in fastboot mode and flash it.
hope it will work.

if you mean that green screen its already shown on my v10 that bootlooping because of hardware failure

What events lead up to your bootloop problem?
If you didn't unlock the bootloader you should be able to get LG or your carrier to flash for you.

To tell you the truth I kind of don't know because it was working fine the day before this happens and when the next day came I try to check the time but the phone was dead.....
Then i relized that 2 days before this happen i tried rooting it which i wasint really good at or even knew how to root it so i download a kdz file and im guessing that is what probably caused but what i dont understand is when i try recovering it using lg support and when it gets to the update mode it keeps on stopping at 50% saying there was a problem between the phone and pc I tried using another computer and it told me the same problem.
P.s. I took it to a phone store they said it could fixed for 60 and they even said it just need an new kdz

Maybe try a different .kdz from here: http://forum.xda-developers.com/showthread.php?t=2107971
Sometimes files fail to download the way they should - maybe you have a corrupted kdz file and a new one will work?
Edit: Or maybe try the official update, you have instructions here: http://www.lg.com/us/support-mobile/lg-LGP769BK
P.S. If I was you, I'd simply unlock bootloader, flash a recovery and format from recovery. Then, I'd flash a ROM.

I think the easiest way is to use LG mobile support tool. refer to this member post http://forum.xda-developers.com/showthread.php?t=2456558&highlight=encrypt
- Boot you phone to S/W update mode
- Run LG mobile support tool (B2CAppSetup.exe)
- Select recover you phone from menu and wait for about an hour
- *Dont forget to comment lg server that you add in host file for offline flash
There're also other way to fix it, if you can boot into Stock recovery by Holding vol- + ... (I can't remember ), but this combo may hard reset your phone if you don't have stock recovery. In stock recovery mode you can use adb to push and replace busybox. I don't try this myself but some member unbrick their phone by this method.

You're on JB rom? Try to flash ICS u-boot/x-loader using Lelus tool first and try again. But for LG mobile support tool it should go pass 15% even if you flash it or not. May be you don't install latest lg usb driver?

I ran into the same issue, I fixed it by flashing the original image via fastboot (I flashed all the partition images):
http://forum.xda-developers.com/showpost.php?p=54479160&postcount=4
You can also try using the tot file and the flashtool if you have access to a windows (which I don't, hence the fastboot approach).

Bricked after Fulmics rom

My Lg G5 (Tmobile) keeps on rebooting to recovery mode (TWRP) no matter what rom I flash. I tried using LG Up software but no matter how many times I install the driver phone is not recognized. Firstly I flashed Fulmics ROM then I installed LineageOS (Cyanogenmod) after that phone was working fine for a while till I saw an update and tried updating it to new nightly version. Please help me out if anyone knows how can I fix this issue.

Btw. Nice tutorial there.
Just a FYI: You want to run this instead. The old command wipes the entire misc partition and you lose your wifi and bt mac address as a result. This one prevents that.

I had the exact same issue. All I had to do was flash TWRP in fastboot mode again to fix it.

Hi friends
This is my first thread created because i see alot of people get into trouble after flashing latest stock os on lg v10 specially Labled as V10 H901
I bought it few weeks ago just flashed latest os 6.0

But in settings as this thread says got into trouble
Searched alot but no solution except replacing motherboard
I disassemble the phone and looked at it
IT WAS V10 VS990 AKA V10 Verizon
Then I downloaded latest vs990 stock firmware and boom every thing is working fine now....
Thanks

No app can be uninstalled and my phone reboots if try to uninstall apps

But how can we edit build.prop? The device is in MM already and it can't be rooted.
Only root can access and modify the build.prop file.
Do you have a method to flash the verizon firmware to the refurbished device renamed as H900 AT&T device?
I tried to flash it with LGUP it says KDZ file is invalid. With LG Flash Tool I've also got an error.

There are 3rd party flash tools you can use and try
Else you can also try boardiag utility by will cracker go ahead and try full tutorial is given in that thread

Try oldest one as it will ignore all restrictions
i have not tried it myself but here is the method to edit build prop without root.
adb pull /system/build.prop <path to save file>
Now edit the file you just extracted and save it
Push it back to your phone via adb
adb push <path to your file> /system/build.prop
You're not done yet. You need to set permissions too
So open she'll via terminal
adb shell
Now from shell, set the right permissions
chmod 644 /system/build.prop
And you're done

Can you explain to us clearly what flashing tool you used and, if possible, what kdz file you used too(and DLLs if necessary)
Everything on this thread seems to be a bluff...
I could not find any evidence of anyone actually being successful flashing the VS990 rom on to an H900.
Until someone has a well-described process and proof of functionality, I don't think anyone here should believe what is being stated.
