[General Topics] Astr4y4L:
Well it sounds as if you've used the (UMMM.....Stock) version of LgUp and tried to flash that .kdz file using the usual refurbish, or upgrade options... problem with that is Lgup when used that way will throw an exception if you try to use a .kdz from a much earlier release... or if you try useing a .kdz intended for a different Vendor even though it is the same Hardware (platform)

the solution for this is either donate and grab my Lgup mod's that unlock (other-than-Stock) options in LgUp.

or Do a whole bunch of research and Go Mod Your Lgup install yourself...

what I mean is this ...

If you use the modded LgUp, you will have a new option called

Partitions dl

and I've purposefully added a line of code that lets the Software Allow (File-Exceptions)

meaning you can on-purpose flash even THE-WRONG-FIRMWARE to your device..

though it may tell you things like

THE GPT HAS CHANGED

THE LOCATIONS OF SYSTEM AND MODEM HAVE CHANGED...

DO YOU WISH TO PROCEED ?

and when you click ok or yes or whatever, It actually flashes the .kdz one partition at a time...

Thus is how I ended up with the Zone3 that thinks it's a K4 !

BUT...

There are some things to be aware of...

If you flash the firmware from a sister phone it may boot and everything just fine but there will more than likely be a few bugs you may need to work around...

EXAMPLE:

Keymapping...

sounds trivial because if your rooted you can use any number of apps from G-play to remap your soft and hard keys...

( Home soft button on home screen) (the Volume up button on the side of the phone ) (the Power button) etc.

But the problem is ...

if you flash a version of software to your device and maby the older model release of the phone had the power button on the back and now its on the side... or had the hard key(physical-button) on the front for home

but now the newer version uses the soft-key (virtual-button ) on your touch-screen instead.

or like in the case of the Zone3...

between version (VS425PP2)

and version (VS425PP4)

the Vendor " I Presume " has changed things in the Modem and so we had zero connectivity upon trying to downgrade.

and in version (VS425PP5) they changed the way the system handles the graphics (patches to drivers)

and so those poor souls who tried the downgrade ended with white & black lines all over the screen and only the lucky and talented ones were able to blindly enter into Dl Mode and flash back to the other version...

These are a few of the pitfalls I've seen while working through all of this...

Does this mean you can't downgrade?

NO!

Does this mean it's easy ?

NO!

But Can it work ?

Absolutely !

And for any one interested I have a modded out rooted system.img from a K4 that i'm eager to test...

Just have too much on my plate right now to go grab a K4 to test it....:(

also working on K3.... So Stay tuned for future developments !

I'm sorry but Team_Astr4y4L no longer supports the old method of downgrading to PP2 To accomplish root..

If you want a fool-proof way to fix your boot-loops , and add stable root to your device...

However you can pm me and we can, for a reasonable donation to pay for my time and efforts in this endeavor, Pretty much guarantee that your device will be rooted and no bootloops with all functions of your phone working flawlessly .

OR if your after Root,

But you Like to do things the hard way....

start at post #1

of this thread, and read through it's all there ...

but unless [MENTION=7383447]MotoJunkie01[/MENTION] has uploaded my original Zone3 Root-kit to his G-Drive you'll most likely have to figure out how to extract the relevant partitions from stock .kdz firmware and then manually modify those to be .img files instead of Sparse-Chunk files (which MUST be done from a real Linux install-- virtual-box vm's don't cut it...) and then find a way place those on the device and then replace the relevant partitions with those created .img files

we used an app to write to the partitions because for some reason it worked when dd gave us a lot of problems.....

But Honestly It will take you DAYS of prep work just to try it.

and you'll probably succeed in DESTROYING your phone.

I KILLED A BOX OF PHONES ON THIS !!!!

###########----As for just fixing your bootloops...----------#######################

STEP 1: go download VS425PP8.kdz

STEP 2: Flash the file using LGuP and choose Refurbish option...

STEP 3: Reboot and your back to stock :good:

IF BY CHANCE LGUP DOESN'T RECOGNIZE YOUR PHONE USE GOOGLE AND SEARCH

LG-FLASHTOOL + MOD + MEGALOCK.DLL

and follow the guides for a G2 or G3.. that works the same for the zone3...

and flash the correct firmware to your phone ! ;)

Hope this Helps,
