Bricked G Pad V500; Tried Everything

Hi all,
I just bought a Nexus 9 and I am selling my G Pad to a friend. I was running the V18 build and been happy with it ever since it appeared. However, today I tried to factory reset the device and it just boot looped complaining of a secure boot error, presumably as I was rooted. I tried to restore the tablet by using the official LG tool and the "Update Recovery" method yet that fails at 4% each and every time. I then tried to do the method found here (which I remember working, but not sure how I got it to work months ago). http://forum.xda-developers.com/showthread.php?t=2692505
I have the drivers all installed okay, the PC is finding the tablet fine, however when trying to flash the TOT file I get "Download Fail" at the same point every time with an error like "00064" every time. I think this could be due to the low batttery and I have no left it charging in download mode (if this does charge?).
I'm not sure what else I can try now, the tablet is stuck in download mode and I cannot do anything with it, any help is appreciated and I can provide info to be more clear if needed.
Thanks all,
Tom.
Hi, I've had the same problem. For me the only solution was to install Windows XP (English version) and the progress bar magically skipped 4th percent. I think it has something to do with LG TOOL not being compatible with some Windows (languages) versions. You can give it a try, please let us know if it worked.

LG G3 boot loop, any solution?

Hi all, I've had some issues with my G3 and have got to the point where I need the advice of wiser heads to try and fix the problem!
The phone seemingly died during an update a few weeks ago, but I was able to fix it using LG's tool and upgrading to Marshmallow. Then a few days ago with no warning the phone froze, and gets stuck in a bootloop at the LG screen, with the flashing LED. If I try to factory reset, I just end up with the Android Droid with a red triangle and I can't get any further. I've tried numerous guides I've found to try and reinstall the stock firmware, all without success. (I haven't tried accessing bootloader as I have download mode available). LG's own tool gets stuck at 4% when I try to recover, and I've tried the LG Flash Tool but get an error at 6% (LAF_READ_GPT_FAILED) using the 8974 dll. I've also tried the LGUP tool but that gets stuck at 6% (Error can't communicate with phone[Kilo Packet]. The phone was not rooted and is a 16GB UK version (model D855). I just seem to be going in circles now trying to find a solution, I suspect somewhere along the line I'm using the wrong combination of programs/TOT/DLL files so I could really do with someone pointing me in the right direction here!

lg g3 d855 in a very strange problem

Hi
am having a very strange problem with my phone, first it was the sim not working, until I continuously remove an install it again and again,
it was first runing on android 5.0 fully OTA updated.
However in a try to resolve the problem, I connected it to LG pc suite in order to get the android 6 ! it was working for a day, but it suddendly it stopped and went OFF for ever.
Thanks to a thread here in the forum, I Hard bricked it then soft bricked it with kitkat 4.4, it worked without any problem, but when the auto updates went to lolipop 5, it stopped again.
I installed marshmallow 6 with flashtool, the phone is working with the SIM without Internet with no problem, but, when I connect it to the net, and specially when I enter my gmail account it goes to the same loop again, and I have to flash it to return back.
Please Help.
Check which version of gapps your using... That's the only thing I can think of

LG G4 Boot Loop!!!!

My LG G4 just of a sudden screen froze so i restarted it and ever since it is stuck in a boot loop showing only the logo. So i as i read some solutions one of them was to do an hard factory reset but with no sucess.
As a second solution was to flash a new firmware but i don't know which exactly because i cant see my actual version in the android settings.
Can anyone help me save my phone please?
My LG model is H818P
(I also found this site but it says there are a lot of firmwares for my model H818P. Please someone redirect me to a correct one. If any other info is needed for the phone please say so. Thanks)

Help my G3 might be hardbricked (hopefully only softbrick)

Hello, I would like to ask if my LG G3 is softbricked or hardbricked. It has been a long while since it decided to boot loop. I tried to fix it but got no results. I tried to factory reset it, but the next day it didn't turn on anymore and got stuck in the logo. Note : the phone was experiencing some heating issue before it decided to screw itself up. I tried numerous troubleshooting from the net, none worked. I also did try to reinstall the firmware to stock again, it did boot but it can't get to the home screen. I then factory reset it again and tried using another firmware also built for my phone (it's LG G3 D855). It failed again at 33% while it was in the firmware update mode. Now that I have left it for a solid year, I thought that it would be nice to try again. Which I did, but it couldn't charge anymore and it cannot boot to the logo. I tried to go to the download mode but no response. I tried connecting it to my computer, but it only detects my phone as a charge only device, it also detects it on only several random occasion. I hope this is a softbrick and it can be fixed at home so I don't need to go to the store to repair it.
I'm sorry for the long explanation, I had been trying to revive it for months now and had no luck. How do I fix this, at least how do I get to the firmware update download mode again? I really really hope that anyone can help. Thankyou so much in advance.
