[LG-E977]Need help, kinda bricked, can't KDZ

Hey guys, i need a little of help because i've never seen what happened to me, i will explain the entire process:
I have an E977 from Movistar Venezuela, it came with 4.2.1, after check everything was working at perfection (wifi, bluetooth, heat, etc.) i decided to root and unlock bootloaders to get into cyanogenmod 10.1 (i had a 4x HD and its very smooth with cm) so i used freegee to unlock bootloaders, installed TWRP and flashed the rom, everything perfect for a month or so, i saw the update of Paranoid Android to 4.3 and wanted to give it a shot so i downloaded it and the gapps, went into recovery, did my backup, wiped and flashed, everything working perfect but i didn't like it so i went into recovery again, did my wipes and perfomed the restore of my backup.
Now, i have a bootloop, the phone normaly showed the LG logo for about a second, turn the screen off, then on again and the OS started to load, but now i just see the logo, the screen turns of but it's not coming back -_-U i've tried to restore again and again and nothing, did wipes and tried to Paranoid Android again with no results, also tried with cm10.1, no results.
I can access the recovery and download modes, followed the guides provided here but i can't KDZ because the original firmware it's more than 1gb and the LG tool can't handle these files.
I read there's a mode to push files via adb when in TWRP, is there a way to "transform" the kdz into some file the TWRP can handle ? do i still have hope ?? I really need help, if you can help me, i will appreciate.
P.D. Also, i would like to know of there's a way to lock the bootloaders again so i can get the phone to warranty! In the worst case...

Did you try the LG Support Tool? It downloads and install the proper KDZ when entering into Emergency Mode.

A way is to restore a backup from another e977.
Another way would be if someone with an e977 would dump his rom to make a flashable zip.
Can't you try lg mobile tool?just put the phone in download mode and see if the tool detects it...

[Q] Stuck in download mode

Hey all,
I recently put the lolipop AOSP rom onto my G Pad, but wanted to revert it back to the stock software.
I plugged it into the computer and tried using the recovery tool, but it did not work, so I put the G Pad into download mode and it gets to a point where it has downloaded the software and is deploying it, but then fails every time.
I tried the offline KDZ method, but when the support tool loads it checks the connected device and always tells me to unplug it and try again.
Does anyone have anything in mind I could try or requires more information to offer a suggestion to me?
Thank you in advance.

I was in the same position a few hours ago. I downloaded the official LG Support tool (drivers and tool available HERE). Launch the LG Support tool, go to Options -> Upgrade Recovery and follow the steps. It should dowload the latest available official formware (V50020D) and flash it to your tablet. I'd recommend a factory reset, since you have CM installed on it. This procedure didn't erase /data (I've done it twice while trying to flash a custom recovery on it). Then you must use LG Flash Tool 2014.zip to flash an older firmware that has a bootloader that allows installing of a custom recovery. After flashing V20B or V20A, you must root it and flash a custom recovery (I'd recommend THIS ONE). It seems a little complicated, but this is the only way to un-brick it (it worked for me).
Get the apk from THIS thread after rooting your tablet (it should flash TWRP 2.8).

[Q] Help Unrooting!

Please don't refer me to any more threads or forums........
I'm sure this has been done and done and talked about but I've been reading the **** out of forums and comments for a few hours now and trying to unroot my Sprint LG G2.
I had it running stock like a champ. rooted it. worked great. then I was attempting to flash lollipop and it required a recovery update (No Problem) I downloaded the correct files and bam! it says your phone is not rooted this requires a root (or something like that) I was already rooted SuperSU installed and root checker said I was fine. so what the hell I swipe to root while inside recovery and it goes to some black screen with tiny text saying fastboot: processing commands and won't leave the screen. I tried booting into recovery and same thing happens. Tried to reboot normal and I'm stuck on the LG logo with my led flashing between blue and green slowly. I CAN boot into download mode and I'm following this

Please help!
When i'm in download mode the phone does say I am rooted. is there a way to just re-flash recovery and restore from my backups I did before all this? if I have to wipe this thing clean and start over I don't really mind I just need to get my phone back haha this is the first time this has ever happened to me and I consider myself tech savvy so idk what I did here (except re rooting in recovery like an idiot) thanks so much!

First question, is the download mode you see with a small status bar or the big one?
If you have the big one, download mode should work. The f flash software will verify the tot file. If that goes through you should be golden.
When it asked you in TWRP to root, that is a message telling you system or ROM file did not take.
If you want cm12, use zv8 tot. Root, auto-rec, update TWRP with blastgator bumped TWRP 2.5.1. Flash cm ROM or aosp, then gapps. And go

to root try kingroot, another option would be to use lg flash tools (to enter in download mode while holding volume up connect it via usb to ur pc), flash KK kdz and root using towelroot.
there is a recovery, TWRP but only works on KK from what i understand.
cyanogenmod isnt available for it.
to go back to stock even with no flags saying u where rooted, just flash a kdz either KK or L (ur choice) and factory reset after.

Flashing a kdz via lgflash tools will reset the counter. U can check by going to download mode and it WONT say rooted in red

Hi, not sure if this thread is the right place to post this, since device is: VK70023A B14.LGE.VK700.0 LG-Gpad 10.1" VK700.0 Lollipop 5.0.2, but rather than start another thread
I'll post it here and hope someone's looking! I'm trying to inject root using this method, so far I've managed to get a copy of the system image, root it, and push it back to the device no problem, lol well, more or less, no problem, but it took a bit of help . The method's for a G4, but I'm pretty sure it'll work for this one too, the last OTA unfortunately broke all the current root methods, tried all of the above and more and, nothing, so in desperation I figured I'd give the G4 method a shot (it's my own image so how bad could it be?). The problem I'm having now is that (and correct me if I'm wrong here, this is my first attempt at flashing this, or any, tablet), when I go back to Windows and run (from Send_Command.exe in download mode):
Code:
#/system/bin/toolbox dd if=/data/media/0/Download/rootedsystem.img bs=8192 seek=40960 count=351232 of=/dev/block/mmcblk0p32
#LEAVE
...the download progress goes to 100% immediately, (the dd params are correct for this tab) but the device just boots normal (shouldn't it be loading 'rootedsystem.img'? Would lgflash tools help here?), I've tried it with and without "seek" and "count" with same result, is there something else I need to be doing to get it to load? The person helping me (even adjusted the 'autoroot.sh' script to work with this device) in that thread doesn't have this device so can only go so far in helping if there's something totally different about the 10.1 that needs to be done. Hopefully that's enough info to go on, everything I've done so far is in that G4 thread but I can consolidate it all and post it here if need be, just let me know, at any rate, if I'm successful I'll probably make a thread with all that in it anyway in case anyone else is having the same problem, tho I don't see many with this model (not sure why). Any help's appreciated!
Thanks in advance

Is there a reason there is no development of this device? CM would be excellent.

need stock rom for lg gpad

I have a lg gpad f8.0 and was wondering if someone had a stock wifi/celluar firmware that i can flash. I'm having some issues ever since i try to do this boot animation it messed up my boot and now lose half my screen the only way to get the screen back to normal is through factory reset but if i reboot the device it does it again.
It's att lg gpad f8.0 firmware im on is 5.0.2

rom
I too am looking for this rom. it does not seem like ATT likes to release any of their ROMs. I am almost tempted to just buy another one and see if i can extract the firmware from it and just resell it, or give it to my daughter for use.

so AT&T V495? Are you rooted? I might be able to get you the stock boot animations but I'm having an issue with recovery. Can you install Flashify and make a backup of your stock recovery and send a copy to me? I can copy the factory boot animation files and send them if you want to give it a shoot. Let me know... Thanks - Bryan

kdz tot
you can try to extract the rom for us if you follow this thread http://forum.xda-developers.com/showthread.php?t=2483250
