LG730 - Venice - Downgrading firmware to ZV5 from ZV8 so i can root it

hey all, just got my 1st smartphone here. the LG Venice.
i love it , but always wanted to root it. that was the main point in getting it.
so i went and got this the other day, and unfortunately the guy at the store
went and upgraded it for me from the good version to this new UN-rootable version.
at the time i didn't know this, or i woulda stopped him.
soooo, I've been reading all over and the consensus is to downgrade it to zv5,
then root it, then save the root, then upgrade back to zv8, then restore the root.
ok, no prob, but i cant get the zv5 firmware to take. i;'ve found only 1 place that has a link to a .cab file. and it don't work.
others have had this same problem, but i cant get ahold of anyone....
if i flash 5 on it, it gets stuck at the boost logo screen. only way to fix is to flash 8 back on it.
so if anyone has an idea or a good zv5 image, or a link or something! or a way to root it as is.. please help!!!
thanx

[Q] Firmware LG G3s D722

Good evening, please could you help me by posting a link with a stock firmware for LG D722 G3s to reset the phone because it does not work I will not turn stuck the boot, booting certification verify
Many Thanks for your help and interest
Angel.

Hi
From what I know LG has not uploaded the firmware files. Or at least not for general public.
Do you have access to your phone through adb?
I fixed my G3s (D722) by replacing the demaged files through adb.
There is a (I think) Chinese board with the kdz files but I was not able to access it yet. I will provide the link ones I find it again:

Can i root my lg g4 with this version? And how?

Sure. Perfectly. At least two different ways. If you do not need and care about device encryption just search for the low effort root in this LG G4 Forum original Android Development. Search for a flashable 10C rom.
If you need device encryption, go to LG unlock your bootloader officialy, flash TWRP and flash su.
Thread for this is right here in General G4. Called complete Guide to unlock & Flash H815 or similar.

Hi, unfortunately this happened to me (more than once) when I tried rooting the first time. You'll need to download the stock image files and the LG Flash Tool to start over from scratch. I'd link you but I don't have enough posts yet to be able to.
The trick is to make sure the rooted image file is over 4 gigs when extracted, I ran into issues multiple times where the download got corrupted along the way and ended up being a few hundred meg. Keep trying and once you get the right files the Low Effort Root is amazing.
Good luck and if you need any more help please let me know!

Downgrade from MM to LL with LGUP is possible!

Just wanted everybody to know that you CAN downgrade your MM LG G4 for Verizon by using LGUP.
And this is how...
1). Download all The Files Below!
1) Firmware Files - Click HERE!
Or Here LGKDZ.com for your exact match KDZ for your model
2) Download LG Drivers - LG Drivers Here - 10.9 Mb
2.1)Verizon Drivers (Verizon Only)LG_VZW - 7.8 Mb
3..LGUP can be found on this website LG UP DOWNOAD
You have to sign into one of your accounts and like the page for them to open the downloads in the middle of the page.
4. install the drivers then the .msi file for LGUP. Usually there is a DLL file and the LGUP application, install the .DLL file then install LGUP.
5. First make sure that your phone is showing up on LGUP, if not make sure you have USB debugging enabled and the you are connected with MTP.
6. Find your .kdz file, and don't press start VERY IMPORTANT!!, Exit out of the application and then REOPEN LGUP and your 13b.KDZ should still be in the box at the bottom.
7. Now just press start and wait for it to do it's magic.
And now your back on LL and you can get back to rooting this phone.
And just so people know it is not possible to downgrade from LL to KK, it will brick your phone for some reason, and trust me I had to send mine back and get a knew one, nothing would get it to work again!
So that's how you get back to LL from MM, which seems to be the only way to have root at the moment...
One more thing, I was able to transfer the files for the effortless root on MM but you can't do any send_command.exe commands because it just says FAIL. but it did switch the system software from Official to Modified so it did something just not what I wanted it to do....

If there's anyone wondering why this works, it's because both the 13b and 24c kdz's both have the same qfuse number, so the bootloader accepts both without bricking. If Verizon ever puts out an update that increments the qfuse value and you take it, you won't be able to downgrade to 13b or 24c.

I have the kdz file but it wont let me put it on lgup. It's looking for a .tot file. Help would be greatly appreciated
Nevermind. Figured it out

would this work with h811

Thank you for the info! Just curious: how do you check the value of qfuse?

I did this on a Canadian variant H812 and it worked. Rooted right after and that worked too. I am a happy camper.
I loaded H81210n.
Anyone reading do note that I did not use the Verizon files above.

What you must do is tick the update and select the kdz file. Then close LGUP, open it again and select refurbish and kdz file should be there. Start the load.
This phone with L and root is perfect. No M for me until root (if it happens). Really enjoy having the changed DPI with root and no permanent notification for Priority mode.

You can DL from here, without "liking" anything. http://www.droidopinions.com/download-lgup-tool/

*edit* sorry did not mean to quote the person above me. I'm asking about actually getting from MM back to LP
Hate to ask this but has anyone verified this? I'm wanting to do this to mine tonight but I don't have near the experience a lot of others do here.

I did this without any problems at all

I haven't done it just yet. And I know I'm not the smartest here. But to my knowledge yes you will lose everything. So always good to back up all your files. I've got all my photos backed up to google photos. over 5000 lol. But yeah from what I understand it's the same as doing a factory reset except instead of factory resetting back to MM you're factory resetting to LP.

(Request to a moderator below my response to stephen293)
OK, I did mine last night and using the refurbish mode as said does in fact delete all data.
((TO MODERATOR CAN WE GET THE ORIGINAL POST UPDATED TO INCLUDE THAT TO LOCATE THE KDZ FILE YOU NEED TO FIRST TICK THE UPGRADE CIRCLE)) I found it down the thread, But just figured it would be easier for others if it was included in the original post. Thanks

Big ups to everyone who made this happen!

Hey sorry but the www.lgkdz.com doesn't work. Is there another site we can find all lg firmware to downgrade for our exact lg variant match....

From OP second 1), try : http://storagecow.eu/index.php?dir=Xda/LG+G4/
or check the XDA G4 section for your variant.

Thank you for your response. I did actually download the H812 kdz from storagecow however when I put it in the LGUP tool it read as an error in the tot file. I'm not sure what happened or where I went wrong. I'm so confused at this point and without my G4 being unuseable at this time. I also wanted to ask if the kdz you directed me to are in fact the file I need to go back to LP from MM?

Request for volunteers - creating debrick image for the d851

Hello, Since the Board Giag Tool Doesnt work for the D851 and the only way to unbrick the D851 is by sending it to LG Repair or Some Other Repair or Flashing it with either Medusa Box or Octoplus Box. It wasnt long when @Kathik figured out that the LG G3 F460 S/K/L which is also not supported by the Board Diag Tool can be unbricked by creating a debrick image. You can find his thread here.
This debrick image that @Kathik used is just a dump of the bootloaders from a working LG G3 F460. And all we need to do is to find a way to create the debrick image from a working D851 running the firmware version the bricked D851 was on before it got bricked.
Fortunately for all of us, i got my hands on the zip file which creates the dump or debrick image (Thanks to @Anik49) We have the file.
So all we need is volunteers to flash this zip file in TWRP and once done, you should see a file name debrick.img.zip on your Sdcard.
If this work, we wont need to send our devices for repairs or dissasemble them when they get bricked.
Please feel free to ask any questions about the process.

I flashed the zip and it said it created the debrick.img.zip but I am unable to locate it anywhere. I'm assuming this is because I am on Stock LG Marshmallow with the slight research I did with the thread you linked.
Sorry bud, I tried. It was the only G3 I had hands on. I hope someone else will volunteer in our community.

Maybe u need to downgrade to 5.0

I wrote in the other thread, the day that I put to work to upgrade to Marhsmallow, i will make the debrick files in some versions as 10c, 10f and other higher ... Right now I have a lot of work and I can not do today. Greetings

Any updates on this?

I would also like to hear from a kind soul as now I have a bricked D851 too

UP , anyone ? im suffring with my D851

I tried creating the unbrick SD this week but failed to do. Seems like the phone was not actually reading from the SD files.
But I have successfuly created the files to unbrick the phone now as long as the phone is in 9008 mode.
