[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

[Q] Bricked Sprint G2 after OTA/TWRP Method Not Working

Ok I have looked and looked and I cannot find a solution for this. My G2 is booting straight into TWRP after the OTA and I cannot get it back. I can get it into download mode but it just sits there at 0% not doing anything. The method for fixing it using TWRP's terminal command mode did not work it just told me that there was not enough space on the device. Should I just smash the screen and take it back to Best Buy to get it replaced since its insured or what? I'm at my wit's end here.

Do you have a backup? If you don't have a ROM maybe push a ROM into recovery then flash.....could also flash stock using lg support too

Thanks man! I got stuck in a TWRP bootloop after the update. Had to use this method to restore phone and end the TWRP bootloop.
Anyone else on Sprint: use the above instructions just make sure to use the LGLS980_20130904_LGFLASHv151.dll not the LSVS file.

This instruction might help.

I brricked my phone LG G2 Sprint and now i am in trouble ...phone not booting..
only i get the sideload via Recovery mode...
need a Recovery TWRP/CWM any...
and the way to flash the Recovery...
as i have changed the build.prop's setting
ro.build.target_operators= SPR
to
ro.build.target_operators= OPEN
and restarted it and then ..the ENd.
phone not starting...
tried to use LG Flash TOOL the .dll and .tot downloaded of Sprint
but the error comes for dll as i have changed build.prop to OPEN
so that LG FLASH TOOL is also not working..
figured out the solution but the way for these solution is still far...
just need the WAY for the solution..
Solution : Need to Replace the build.prop(OPEN) which is edited ONE ----> to-----> Original build.prop(SPR) [so that can use your said procedure]
if can't replace then should be able to edit the OPEN to SPR again
Only the things can work thru SIDELOAD only.
Also need a way to flash the Recovery in LG G2 SPRINT (so as to push or edit the build.prop) that to via SIDELOAD
The WAY : ? ? ? ? ? ? ?

It worked..
The thing is that while installing devices drivers n stuffs
Sometimes some file are skipped unknowingly.
But again if u reinstall on same device without formatting then the issue remains unchanged.
So for that reason u should either format the OS n perform the said things/procedure.
Or just switch the computer or laptop to other.
Just Simply works...
It's like digging a mountain n getting an ant...

There isn't one that I'm aware of. Last night I was looking. If you're on a custom rom/recovery just install the stock rooted rom and install flashify and install the stock recovery which is floating around here somewhere then unroot. you'll be able to receive the update after.

help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I wish there was one, too. My tablet is bricked into fastboot boot loop and the LgMobile support tool does not work. Only hope is LG Flash tool. But I need the kdz.
Is there a way to convert an image (zip) into kdz?
EDIT: I found (with a lot of help) a way to unbrick it with adb.

Please message me all the details that are needed in order to unbrick my LTE V410!!!
I have two tablets one is mine and one belongs to my son. Both are bricked!
Please H*E*L*P

This is the link with all the help and the steps I took to unbrick my tablet. Although the thread was for another model, the help I'm given is for the LG G-Pad 7.0 v410.

I basically had to flash TWRP recovery and then the stock ROM (which was rooted). Check #37 of the above link.
If you want to upgrade to lollipop you will have to flash custom recovery and unroot the tablet.
Things you may need:
TWRP recovey found here. Scroll half way down, make sure you use the right image for your model.
Stock ROM found here. Note that stock rom is rooted.
Minimal ADB and Fastboot found here. Or you can use adb.
If you need any more help, please let me know.

HOLY SH*T!!!!
:laugh:
WOW! I followed these simple instructions and fixed the first tablet in under 5 min. My son's tablet wasn't primed and ready like mine was. I had already tried every little trick n trade I could find on the net...which consisted of "NOTHING"!!! really... Kept coming up with the same ole bricks though. Until this VITAL information surfaced!!! All I had to do on my first tablet was open up TWRP Terminal and enter the TWO codes.....rebooted.... Now enjoying!!! You got definite props from me bro! :good::good:

v410 kdz can be found here

LGUP - NEW!!! - INSTALL KDZ - MM or LP - FACTORY RESET/UPGRADE

NEW software!!!!!...... LGUP WILL FLASH YOUR KDZ files
Download LGUP from here http://www.filedropper.com/g4 or here https://www.dropbox.com/s/d2dw48uqh4hku8m/G4.rar?dl=0 or here http://oceanhost.eu/eps4h4pmwphu/LGUP.zip.htm thank you hyelton for this link :good:
Install LGUP_8994_DLL_Ver_0_0_3_23 first and then LGUP_Install_Ver_1_14_3
Make sure you have downloaded the required KDZ file MM or LP
Start LGUP prog on your computer "make sure your phone is plugged in"
ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.
THANK YOU FOR THIS Killerdog:good: <~~~To Modify This File You Must Have Root!!
For me it's show in LGUP as unknow device.
reboot my phone, remove battery and anything else don't work.
I install LG Bridge to test, and nothing seem to work.
After make some test and search, i find some info modified by S3V3N into his rom (cust partition) that he have modify into this file:
/cust/OPEN_COM/cust_OPEN_EU.prop
Code:
ro.lge.swversion=[COLOR="Red"]some info[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]some info[/COLOR]
change to
Code:
ro.lge.swversion=[COLOR="Red"]H81510c[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]V10c[/COLOR]
restart my phone and woow it show correctly in LGUP and i can refurbish my phone.
TO UPGRADE TO MM from LP - make sure BIN file is ticked and in the File Path point it towards the MM KDZ you have downloaded. MAKE SURE YOU HAVE CLICKED UPGRADE! This will update you from LP to MM with out wiping any of your info. Press Start. Make cup of tea and be patient
TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient
TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient
If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
YOU WILL LOSE ROOT!
There is no need to enter download mode! LGUP will do it for you.

INSTALL TWRP
Make sure you have ADB and Fastboot installed.
I always put TWRP.img in the ADB folder - so if I want to boot into TWRP with out installing it this is what I do:
make sure you open a command prompt in the ADB folder "VERY IMPORTANT" and type:
adb reboot bootloader <enter>
fastboot boot TWRP.img <whatever your TWRP image is called in your ADB folder><enter> dont forget the .img at the end
That will re-start your phone straight into TWRP - You can transfer files to and from your computer while in recovery.
If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" then press install then select images then select recovery NOT BOOT then swipe to flash. This method does not install TWRP app on your phone, all you need is a reboot app from the play store that will re-boot you into recovery.

Not sure but I'll put that in the op cheers.

Do you need root so use this method to upgrade to marshmallow ?

H81520A_00.Kdz flashed (by upgrade option) succesfully. It takes 10-15 mins(longest part is "android upgrading" screen.), and i lost root access. By the way root access is not necessary for upgrade.

So since it wasn't clarified, I'll be the one to ask...
Will this work on a unit without root (which is yes according to the OP), and without a bootloader unlock, ie the Taiwan (TWN) variant of the H815.
I completely understand it's a complete wipe and root will not be retained.

I would also like to know about this..... will it work on a unit with a locked bootloader... TWN variant?

downloaded from a different mirror re flashed no problems

Hello downgrande wokrs?
