Stuck with Fastboot , now stuck in Recovery with no adb

I Have an LG G2 - Sprint phone the LS980 , been experimenting with it lately , however the last experiment went all wrong
I flashed the stock Rom of the Indian version KDZ file using the LG 2014 Flash tool, I was able to boot but Obviously there were a lot of issues using the OS . However on the next reboot I was stuck in a fastboot loop.
While in the fastboot loop , I was able to erase all partitions one by one and flash back these specific to the ZVC firmware http://downloads.codefi.re/autoprime/LG/LG_G2/LS980/Stock_Firmware/zvc_partitions/
Now I only have Recovery mode and even though I have recovery mode , I cannot adb sideload a file as the system keeps saying it cannot detect a device !
I also tried the Download mode , I can enter the Download mode , but the LG tool will no longer flash it.
Any suggestions ?

Was able to get Download mode going with LG Flash tool , but I now get this error.
ERROR: laf Partition has Changed

that means you don't have a download mode image installed.
How did you go to 5.0? Via TWRP or a KDZ? (the answer to this question changes the answer I will give you on how to fix)

Twrp.. Androidnow 3.2

The only way to get out of fastboot mode is to use fastboot.exe and push the laf.img and boot.img to your phone to boot up. However there is no laf and boot images for your phone yet(I think) so there isn't any way to boot your phone up yet.

some one can help me please ?? the LL 5.0 is sucks

Please help me ! Up

I had the sam problem.Now it is working .So you need to download latest firmware for you lg model(kdz file)
Then use this guide: http://forum.xda-developers.com/showthread.php?t=2600575 (extract kdz file)
Now when you extract it find laf and boot there will be some numbers just change it to laf and boot.
In fast boot erase and flash it again.If you have d855 international i can send you these files.

[Q] Softbricked LG G3 Bootloop

Hi, new here.
I do believe you guys aren't too keen on US Cellular. But I have all of the files I need. It's more of an overall sort of question.
So here's my situation:
I was being stupid and messed with the permissions on my phone, not knowing what I was doing(trying to get titanium backup to move apps to the sd card). Well, it messed up my phone. Anyways, I tried a few things to fix it and then it got stuck in a bootloop.
I am currently able to get on TWRP and fastboot. I need to get the LG Flash Tool to see my device to flash the stock KDZ but it won't see my phone without Download mode. I wanted to put my laf.img file onto my phone through fastboot to get Download mode back. My phone will show up on my computer, but when I try any ADB or Fastboot commands, it shows no devices.
Is there a way to flash my KDZ without restoring my Download mode?
Is there a way to put the laf.img onto my phone since my computer cannot see my device(through asb/fastboot)?
Is it possible to convert the laf.img into a zip and flash it through TWRP and get my download mode back?
Thanks for the help, and sorry for the long post.
UPDATE I screwed myself a little on this one. I no longer have TWRP, it goes straight to fastboot. Any Help Please?

What model do you have?

It is possible to make an update.zip to flash the laf.img to the laf partition but I don't know how. Also you can use fastboot to flash the laf.img just boot to fastboot plug your phone into your computer and run fastboot flash laf.img laf
That should do the trick. Or you could flash a rom to fix the permissions. Any US cellular compatible rom should work.
Also TWRP has a file manager that might be able to fix the permissions if you remember what they were.
Hope that this helps.

Secure Booting Error! Cause: boot certification verify

Good day mate. My brick phone is F460S variant. I got this error when I tried to go back to Lollipop using Lg flash tool 2014, it got stuck on 5% and remove usb cable and start again, after that I got this error Secure Booting Error! Cause: boot certification verify.
No download mode
No recovery
anyone can help me please?:crying:

anyone?

You have triggered the downgrade QFUSE. There is nothing you can do apart from trying to unbrick it like it was dead, but that's not guaranteed to work. You should have researched more before attempting this. My prototype doesn't have a QFUSE, so i am free to downgrade via TOT to kitkat or lollipop.

I second you on this. I just uninstalled MultiROM and got the secure booting error. Depending on the ROM you have, find a bumped kernel and flash it. Most of the kernels on XDA are pre-bumped unless the developer states so. Boot into recovery, tutorials on the internet, then flash the kernel and voila.

if you can use twrp or you're able to flash, use mr_bump.zip: https://mega.nz/#!DNwhRBrK!Ki6zIzXca0KjPShi6L2oaCYIr0CkmH8sEymEt-0Q3ys
oh sorry, I didn't see "no recovery".

Hello, i got the same probleme and i've trying a lot of things but not resolved..
My phone is a LG G3 Beat F470s..
Please help us..

Dowblnload adb and fastboot drivers
Download laf.img for your device
Download LG Drivers
Get you G3 to fastboot mode. Hold volume up and connect it to PC
Open fastboot and adb folder in PC, ctrl+shift+right click and open cmd. Type fastboot devices...if ur device is listen then proceed, if not u did not do something cotrectly...if yes just flash laf img to your G3 and voila

I remember me that I was in the same situation:
No TWRP, no download mode, so i have use in pat this thread:
https://forum.xda-developers.com/showthread.php?t=1752270
And an other that i haven't found again (xda thread), in some lines:
=> download the last img file from: https://eu.dl.twrp.me/d855/
=> no download mode available so no possibility to flash manually twrp file from an LG Flash Tool
==> so setup an adb connexion to the phone, cp command to copy the img file on the sdcard or where you want
=> command: "flash recovery twrp-2.8.x.x-xxx.img" (https://www.xda-developers.com/how-to-install-twrp/
=> if it's as worked, you could reboot manually in twrp, make again the partitions if needed and flash any ROM.
