[Q] ZV6 to ZV4? - Sprint LG G3

I have a Sprint LG G3 (LS990) and unfortunately it has ZV6. Is there a way to downgrade to ZV4 so I can root it and install a new boot loader? My search foo is weak here and the amount of ZV6 threads is insane. lol.

This needs to be moved to Q&A but to answer your question. Follow this thread here it will point you in the right direction

Upgrade to GPe

My device is C6802.
I am on 14.2.A.1.136, android 4.3.
I lost previous root upon OTA upgrade.
I tried to search exhaustively and found no good guide to upgrade to GPe 4.4.2.
Can someone kind enough to point the way to me?
Shouldn't have to search as there is a good sticky in the general section on getting root and ready to flash ROMs
Have a read of the TA one and the downgrade one while you are there.
Once you have read them, read them again and then ask any questions you may have

LG G3 ZV8 update with flash tool
I wanted to update with the flash tool seeing as how I am on ZV6 with no root or custom recovery installed, but it needs a .dll. Do i use the stock .dll or is it just missing from here?

Yes. Or if you need it, it's linked the the General Flashtool thread.
I was wondering if anybody had mirrored the system img yet? If so that would be amazing, please and thank you!
The same as everyone Else!!
Just to thank you excelent work !!!
Solo para darte las gracias excelente trabajo amigo!!
Can someone describe how I would go about getting the system.img file?
System image from ZV8
I have extrated from the tot all the system files, merge them in an image file, i've used WindowsLGFirmwareExtract-1.2.5.0-Release but i do not know if it was done the right way, can someone take a look at it, I am uploading the file as soon as it finish will post the link it is about 2.81GB.
Where is the ota zip file at. I'm shocked it's not here yet
Flash2 from ZV6 to Lollipop?
autoprime -
Apologies if this is a stupid question, but i used your flash2 method to update to ZV6 and preserve root. I was wondering if the same method will work to get me from ZV6 to ZV8? If so, which .img files do I need to dump in which folders?
Thanks in advance - I really appreciate the work you do, and the help.
The file from the LG website that was posted is just a tarball of source code. It is NOT the OTA update and hence cannot be flashed by anything.
Lg G3 zv8
LG's website has the zip file called "LGLS990_G3_Android_L_ZV8" Could this not be downloaded and put on the sd card, reboot into recovery and loaded that way? It won't let me post a url but here's my attempt... opensource(dot)lge(dot)com/osSch/list?types=ALL&search=ls990
Usually when I go to that site I still have to type in LS990 to get the page with the files on it.

That file isn't an update or image of any sort. It's just an archive of source code LG released in order to stay compliant with the various open-source licenses from Android and whatever else they used.
ota
Did anyone get the ota zip yet
Just to be clear.... sorry for being a noob... If i want to keep root, Its wise to wait for the update to officially come out & be made into a flashable TOT? I do not know how to use the ADB tool & I refuse to lose root.

If you are rooted and have custom recovery just go here http://forum.xda-developers.com/showthread.php?p=58846091 and flash the pre rooted rom.

new to the g3.

Hello everyone. I just got my g3 the other day and it is custom for me to root and maybe install custom Roms on my new phones. My question is if I root with purpledrake can I install roms? I am seeing there is no unlocked boot loader so that is why I am asking. Any help would be appreciated.

Downgrade and/or Root ZVF

Hey all. A new user (@Spikerbond) has 30 LS990s on ZVF that he needs to either downgrade and root, or just root if root is available for ZVF yet.
He doesn't have enough posts to start a thread, but I thought his question is a good one so I created this thread for him. I told him this other thread is a good place to start to learn about downgrading, but I was hoping more people could chime in and give him specifics on the best route to take to root all 30 LS990s on ZVF.
Use the lg rooting tool in this forum, I was on zvf and it worked for me
