Have never used lg official flashing tools but there are numerous threads in the guides section re patched LGUP.
Have used them numerous times and they definitely work. Are you using a different rom? if so, how did u get there? If not, maybe just do factory reset?

[Q] cant flash roms cant flash kdz through updater e975

hi guys
so there i have a difficult situation on the e975
i flash avatar rom through cwm and after a while using it i decided to go back to stock rom through kdz updater from lg, ive done this several times in the past with no problems but this time it stuck on the lg animation, after that i decided to try teenybin so i can have a custom recovery to flash roms, the problem is that teenybin completly destroyed my phone, not even cant flash roms through sideload but the original/stock recovery has gone so i cant get to lg to fix it
so any way of help here?
i can access download mode and fastboot
(when i try the kdz updater while the phone is on download mode it jumps to fastboot and the updater cant do his job)

Try THIS tutorial to flash your kdz.. Also it's wierd because if you succesfully flash an kdz file (using any method) you should be completly (re)locked and unrooted.

i can barely remember what i was doing, im sorry
if you come from 4.4 you can flash through the lgspst from the teenybin thread the 975 kdz file by renaming it to bin, and then because you are with the ls970 dll file, you can root it, flash cwm through freegee then go to cwm and clear everything (data cache sddata system dalvik nothing else) and then go to download mode again and flash the original e975 kdz through the kdz updater, its a lengthy process but thats how i did it until i or someone else find another more short way

G Pad 8.3 Australian boot recovery problems

Hi,
I've decided to base this thread towards other Aussies/Kiwis and I want to ask if any of you have managed to successfully install TWRP or CWM on your V500 tablets?
Because I have literally tried every single thing I could find, after scouring the internet for many many hours, including having bricked completely one device, and I have not been successful in installing a custom recovery.
My colleague thinks it might be because the Australian version of the stock boot loader differs just enough that none of the methods work. (He's tried as well).
So, anyone successful? Because far out I cannot STAND the LG ROM!
Thanks
Take a look at the CWM manual installation instructions. If your aboot is unsupported, then you probably need to downgrade your firmware with lg tool 2014. I posted links to the files you need on post #36 in the CWM thread also.

Hmm, I had tried V50010B, V50020a and V50020d, but I don't think I tried V50010a. I'll give it a go and let you know how it goes.
You might not need to downgrade your firmware with lg tool if you can successfully complete all the manual installation steps on that thread.

Thanks so much dude, I got CWM on it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! You gave me the motivation to try again.
Thanks to everyone involved!
So, I rolled back to V50010_A and the followed the instructions, and got CWM. I still get the secure boot error for a couple seconds which almost had me smacking my head, but then it went into CWM and I jumped around the room
Good to hear. That secure boot error message is normal when you install a custom recovery.

you can try using LGUP for the lg g3, it's look like flash tool but it's so easy to use and don't give so many errors like flashtool.
see one of my post it's called "LGUP new tool for flash tot and kdz" i think.
if that doesn't work try installing other version of windows on a partition and start the flash since there obviously installing first the drivers.
hope that work to you

How did you restore stock? I flashed kernel but was on custom rom. Phone got stuck on bootloop. I can't enter recovery or fastboot. LGUP fails because i can't cross flash my Sprint to any other KDZ. Any suggestions on what i can try? thanks

Did you root your phone? If you did, you can use Qfil to restore your stock boot img (if you made a backup). If you didn't, you'd have to get someone to send you their boot image. I would have sent mine, but I cross flashed from Sprint to Open US. I doubt mine would work for you.
Why can't you cross flash?

To cross flash? Yes i found one, but it's via TWRP. Right now all i get is logo, "your device software can not be checked for corruption.." and screen off. I can only enter Download mode. If i can at least restore recovery i can cross flash or install custom.

No I didn't. Did you clear stock modem file from QFIL?
You should clear modem and some other files stated in that post. Then you select all partitions in LGUP except one file also stated in the post. (I can't remember the name of the file)

yea i cleared the files mentioned in that post. and also cleared modem. Any kdz i flash, the first message i get is: this phone is permanently locked. it can not be unlocked. before this i tried some guy's backup from TWRP of his lg g8 sprint. i got lots of errors popping up when it booted. i think that's where my sim whatever got messed up.
From my research, i think a file called fsg has something to do with sim working. Also my IMEI is 0. any suggestions would be highly appreciated.
