I've had this phone for a few days and I bricked it by reverting my build.prop from this thread http://forum.xda-developers.com/showpost.php?p=55838361&postcount=2 . It is an unlocked phone T-Mobile D959 on 4.4.2. I was having lots of trouble and crashing apps so I decided to start fresh and replace with this file from the thread. After replacing, it does not allow me to boot. Factory hard reset does not work (since I believe it does not change build.prop). It shows Android mascot for ~10 seconds and then black screen. If I start phone normally the screen will boot LG logo then go to black with front notification light constantly flashing from cyan to green and looping.
I do not have a custom recovery and I can only access "Download Mode." I have tried the KDZ flashing with LG Flash Tool 2014 with LG_KDZ_FW-Update_OfflineFix. I keep getting an error at 2%/3% of the last step depending on the setting (3% on CS_EMERGENCY, 2% on EMERGENCY, 2% on DIAG). I am putting the phone on COM41 and tried both USA/KITKAT KDZ files.
Does anyone know what settings I need for this method?
I have also tried the LG Flash Tool 1.5 with TOT using a different variant's *.TOT file in hopes it would work long enough to boot/think of a new solution but this fails due to a cross firmware check.
I see that some people on this forum were able to do it then fix their phone after a few more steps. Someone used a .DLL from another firmware and the program let him flash. Does anyone know of any programs (or tricks to bypass cross firmware check) I can use to flash a different/wrong variant's *.TOT file?
This is a strange part of the 1st log file:
"[ 7:20:12] Cross D/L Fail, phone : LG-D959, binary : Unknown
[ 7:20:12] Download exception Error
[ 7:20:12] ¡Ú¡Ú ERROR REASON : LAF_ERROR_INVALID_INPUT_FILE"

Make sure you have internet connection. And boot to "download mode." Plug your phone into your PC, open up the LG PC Suite software that comes on the phone. If you don't have it just go to http://www.lg.com/us/support-mobile/lg-D959
About halfway down the page will be a download link for the "pc suite". Download it and run the .exe. Once you have it opened up click "mobile devices" on the top toolbar. And then select "Restore upgrade errors". And let it do it's magic.
I know this method works. I used it 2 days ago in kitkat and have used it about 20 other times. Due to having no custom recovery, once I softbrick this is what I have been using to come back to stock unrooted kitkat. Then I use " Dfuse's downgrade and unroot the easy way"

Thanks for the reply! The LG PC Suite method didn't work. It went through all the steps then failed.
Dang.
Need help to unbrick my LG G Flex F340L software version f340l20b. It was rooted using towelroot. later I installed SuperSu app. But due to this OTA update was not installing. once downloaded during installi it was giving an error like "Your device is suspected in rooting. System update is not available for rooted device".
Later I installed flashify app from play store and tried flashing CWM recovery. Once recovery installed, phone tried to reboot to recovery where I got Secure booting error message. But the most terrible thing happened immediately after that. During that time OTA update downloaded once again and started installing. immediately after reboot, my phone is stuck in below screen. Now that its almost 3 days, my phone is in the same state. Even if I connect it to PC, though it seems that the phone is switched off, in PC I can see quite a few disk drives prompting for formatting those.
ERROR: Boot certification verify

Thanks for sharing similar experience in a different thread. I installed CWM in my LG G Flex f340l20b. Once after that, while OTA update getting installed, my phone gets into this situation where there is no download/recovery mode, only LG logo comes in the screen along with security error. phone is getting detected as qhsusb_bulk and getting too many disk drives asking me to format those.

Do you have tot or kdz file?
You can extract these file from kdz or tot.
Only 10 files are needed

Thats method is too clear.
1) U need 10 files aboot, boot, laf ,dbi ,sbl1, rpm, tz modem, recovery, misc.
U can extract these file from tot or kdz using lg firmaware extractor.
Note....kdz doesnt have misc file and it doesnt matter so dont worry
2) you need to install qualcomm driver and if yellow mark then disable digital signature enforcemt.
3) copy these file to unbrick very partiton tool folder.
Note..
If u extract these file from kdz or tot then these file files will be in .bin format then you need to simply rename the extension from.bin to .img
4)
See the disk managemet on your pc and find which disk no. Your phone showing.
If showing disk then run 1hardidsk.bat/exe
If it say disk2 then 2hardisk.bat
5)
Keep in mind.
D802 d800 d801 d805 d803 all have same partition table for these 10 files.
So if u dont see any model in the kist choose d800 or d802..
After its says continue close the window
And swithc off your phone by long pressing power button for more than 15 second so that phone turned off.
After turned off press and hold vol up button and conncet to pc.
If you stuck in download mode screen and didn't get firmware update screen
Then do this trick.
Switch off.
Press and hold vol up and connect to pc.
As u see download mode scree.
Keep pressing vol up many times
Around 30 times.
f340l20b bricked
Need help to unbrick my LG G Flex F340L software version f340l20b. It was rooted using stump root. no twrp/cwm backup file.
few days back I installed SuperSu app and removig the un-necessary apps. mistakenly i select the one of the widget file and delet/unintall it.
it was working good but for any reason i restarted my phone..... huh.... it has a boot loop of LG logo and ULteA repeatedly, no recover mood except flash mood.
i tried multiple time kdz firmware and lg mobile support tool with imei but got stucked at 49% every time.
plz help me to get ride this problem ....
Hey all, thanks for reading. I've caught myself in a predicament. I can solve most issues that crop up my way, but right now I'm a bit stuck. It is likely fairly simple and I am just dumb...
The huge issue here is that I am running stock lollipop for the D415 model. I am having the typical base-band and WiFi issue that a lot were having. Like most, I just booted up into TWRP and restored a backup. I Wanted to try again so I flashed the stock ROM and tried again; didn't work...oopss..
LG Flash Tool refuses to locate my device. Download mode fails to connect my device properly. Error is:
EP1/out FAIL nfo=40 pg0=ffbd880
usb_read() transaction failed
So now I am stuck with a broken stock ROM, no TWRP, and no current way to re-flash a stock ROM.
Steps taken so far:
1. Reinstall all drivers
2. Attempt to root and install TWRP to access my backups (No access to Download mode)
3. Started all over with original USB.
What can I do? Thank you again for reading my long post.
Came back to it after a few weeks and issue has been resolved. Despite error warnings fastboot operated correctly, only manually. Any script etc. that booted device into fastboot would never find the device. Simple as flashing recovery and restoring a backup.
tl;dr: I'm not very bright.

EDIT 2: Device is properly configured and can be found in ADB when powered on.

hey man, thanks to reply, i tried the testpoint, then could flash the original rom of mi a2!!
Hey everyone,
after spending about 5 hours trying everything I could think of and what I found in all kinds of forums, I'll try here before the phone is gonna be burried.
Got a "dead" P10 from a friend - booted straight to an error page with the headline "Your device has failed verification and may not work properly." My guess is that it was supposed to be updated, didn't have enough memory and then crashed.
Here's what I tried:
Factory reset - aborts at about 25%.
Download of a new firmware version via WLAN - aborts
Upload via SD-Card (dload) - firmware update failed
The phone is not recognized on the PC - so wouldn't know how to flash it from there.
I can still access it via fastboot, but I actually don't now how that could help me
Can anyone think of anything else that could be done?
LG
Maxi
Somebody got any idea?
