Another idea. In a previous thread for this device, I outlined a short guide on my 5.1.1 Rooted, Debloated, and BusyBox injected Stock ROM (Vs425PP2. ) For those with all the issues getting VS425PP2 to stick after downgrade, another option is to root install Flashfire, and flash my more stable version of Stock VS425PP2. At the time, I dumped all partitions from a Rooted, Debloated & BusyBox ready ROM. It is not downgraded, but completely stock VS425PP2 which has never been upgraded to a more recent build. Now that someone has finally figured out how to downgrade to a point of being able to root, I will find the link for my stock 5.1.1 VS425PP2 partition dump. Thanks much to [MENTION=4977646]help10[/MENTION]1 for his hard work in unraveling the mystery of the .kdz downgrade. Genius ideas. Again, you guys that have downgraded to VS425PP2 from a newer build, once you get root access, flash my stock rooted VS425PP2 for a more stable build than the downgraded stock version.

The following "image" files are not in fact images, but compressed format type files. The /system partition is fastboot flashable. It may also be flashed to your VS425PP using FlashFire by [MENTION=631273]Chainfire[/MENTION]. Alternatively, an app called Partition Backup & Restore is likewise a viable option. The easiest way is to install Flashfire, make a backup of your boot, recovery and system partitions and save the files to external storage. Then, replace your backup files with my boot, recovery and system files and opt to a Restore option from FlashFire. The app will flash your device with my boot, recovery and system partitions in full. I haven't tried, but using the EverRoot option in Flashfire will very possibly allow rooting of newer builds.
[General Topics] wperdigon:
does anyone have a simplified walkthrough for how to root using your guys methods?
[General Topics] MotoJunkie01:
You make a good point. With [MENTION=4977646]help10[/MENTION]1's approval, I will update the OP to include the downgrading method he discovered. s well as an option to flash my stable rooted 5.1.1 VS425PP2 ROM. I think getting all methods to date for rooting, condensing down, and updating/cleaning up the OP will be the simplest way to do an updated tutorial.

Who is going to compile twrp guys? Come on, I don't even this l we are dealing with a locked bootloafer here [MENTION=4977646]help10[/MENTION]1, when you get a moment, I'd like for us both to work on the OP
[General Topics] Merazomo:
I've been downgrading and upgrading my VS425PP5 phone for a few days now, and I still can't root my phones with certainty. Eventually I get it done, but not without issues each time. Now I can't get my VS425PP5 downgraded to VS425PP2 to root LOL. I'm using the same files I used to downgrade and root as last time, but now I can't get it to root. I'm gonna write everything down until I can root it at will without any issues.
[General Topics] Merazomo:
Could you please be a little more specific. I managed to do exactly just that, but the backup of the boot - recovery - system partitions, where saved in a single folder on my MicroSD card. The folder has these files: boot.lz4, boot.md5, recovery.lz4, recovery.md5, system.0002.md5, system.0002.tlz4, system.md5, system.tlz4, twrp.lst, twrp, twrp-busybox, twrp-lz4c. Yours are only 3 zip files. I will include the screenshot in an attachment.

**UPDATE** After researching everything a little more. I learned that these partitions are called Fastboot backups correct? Can FlashFire even restore Fastboot partition backups? From all the information I'm gathering, at some point I'm going to have to put the phone in Fastboot mode, and this phone just doesn't go into Fastboot mode; I've tried it many times. Second time around I tried to backup the boot - recovery - system partitions as Fastboot backups to the MicroSD card, instead of normal backups like the first time; the phone just rebooted without backing anything up. The first time, at least I could see a black screen with white text flashing some files.

Another thing. The firmware in my phone is very easily corrupted, so I have to do all the steps one by one without any errors whatsoever, or the phone will get stuck at boot up, and I have to start from scratch. At this point, all I need to do is find a way to replace my so very corrupted partitions with yours, and hope that it makes the phone stable.

HERE ARE THE STEPS I TAKE:

1. Upgrade to VS425PP4 on Refurbished with LGUP - Everything goes smoothly, no reboots at startup

2. Downgrade to VS425PP2 on Refurbished with LGUP - Can reboot 1 to 100 times at startup, finally boots up

3. Install KingRoot v4.5.0 - Can reboot 1 to 100 times during the process, 6 out of 10 times it roots my phone, the other 4 it corrupts the firmware

4. Install Super-Sume v6.4 - 7 out 10 times it removes KingRoot and installs SuperSu with root, the other 3 times it corrupts the firmware

5. Install FlashFire v0.53 - installation always works, was able to backup onto MicroSD as normal backup but not as Fastboot backup

6. Dead end, don't know how to replace the stable partitions with mine.
[General Topics] klaiiii:
Did the system tag the wrong user?
[General Topics] Merazomo:
Never mind. I managed to flash the boot, recovery and system partitions from the Rooted, Debloated ROM. I used the Partition Backup & Restore App though; it was a lot easier. The bootloop at startup still persists, so it's probably never going to change. I know the three partitions where replaced, because if I do I factory reset, it restores to the Rooted, Debloated ROM.
[General Topics] MotoJunkie01:
We can probably fix the bootloop. In addition to the /boot, /system & /recovery partitions, I have partition dumps from VS425PP2 for all 26 firmware partitions, including /aboot, /laf, /rpm, and /sbl1. My guess is the bootloop is caused by either /aboot, /rpm, or the secondary bootloader /sbl1. You know how that works, on LG or virtually any brand, try downgrading primary, secondary or application bootloader, and normal bootup gets extremely buggy.

Edit: [MENTION=4977646]help10[/MENTION]1, if you have time, perhaps this idea would be worth exploring: while technically "downgrading" the ROM Build to VS425PP2, is there a way -- when decompiling the .kdz itself -- to allow for the more current /laf, /rpm, and sbl1 partitions, while still allowing the OS Build itself to downgrade? This may well fix the bootlooping issue. And if not, hey its a minor price to pay for now to finally have a universal rooting method for the Zone 3.
[General Topics] wperdigon:
motojunkie, any luck with progress on this platform? thanks -
[General Topics] MotoJunkie01:
Yes definitely progress. My goal is to iron out all bugs present in the downgraded OS, and allow for a normally functioning 5.1.1 Stock ROM. I am nearly there. I'm working on display drivers now.
[General Topics] wperdigon:
merry Christmas - any updates?
[General Topics] OhMattyO:
Awesome, glad to hear there is some progress! Is there anything I (or anyone else for that matter) can do to help you in this process, testing or otherwise?
[General Topics] MotoJunkie01:
What build are you running on your Zone 3?
[General Topics] OhMattyO:
I have a few Zone 3's running the VS425PP5 build.
[General Topics] MotoJunkie01:
Do you have at least one on the PP4 Build?
[General Topics] OhMattyO:
Unfortunately I do not believe so, I picked them up all at the same time at Best Buy and they all appear to be identical.
[General Topics] MotoJunkie01:
I have one idea that would provide a universal root method for all 5.1.1 Builds for the Zone 3. Force the device into fastboot mode and flash my rooted, debloated stock ROM via fastboot commands. From what I can tell, the bootloader isn't locked on the VS425PP, but somebody correct me if I'm wrong.
[General Topics] OhMattyO:
From what I have read, the bootloader is not locked. So I'd say give it a shot. Let me know if you want anyone to test on a PP5 build, or if there is anything else I could help with.

Right so how are you going to root ?

and what are you going to do to remedy the bootloop issues associated with downgradeing?

with my new Donate-Only Root method you don't even have to fool with downgrading...
[General Topics] Heimish:
Just sent donation. Weird thing is, I tried it on a second phone and the LCD stops working (white screen) on PP2, but when I go back to PP7 it's working again.
[General Topics] Heimish:
Did you try changing this setting?
[General Topics] Astr4y4L:
Problem with old method.

Brother we got your donation and will ba available to assist in a bit.

But that was a common problem with the old method.

So flash fresh to PP7

And i will send you a link to download in a few.

We are going to bump u up to the new method.

It usually cost $20 but im going to believe if we help u u will surely be happy and donate the other $10 afterward.

---------- Post added at 12:30 PM ---------- Previous post was at 11:30 AM ----------

yes tried it. and that stuff helped connect to the networks, the problem is I've got to modify some things in Framework to get it set right...

also edit APNS.xml and some other small changes...

I'll figure it out eventually just takes time...

ok so holy crap your k4 image worked ! umm so for testing .. what would you like to know ?

First of all I "dirty flashed" it and I didn't lose any of my settings which is kinda awesome.

texting works ..voice calls .. what else ?!

I used app manager to remove disabled apps with root access and that WORKED. Maybe some minor details... wallpaper doesn't appear on lock screen. After uninstalling apps and rebooted sometimes it hangs at "android is starting apps"

---------- Post added at 06:58 PM ---------- Previous post was at 06:52 PM ----------

steps to root the easy way,

STEP 1:

unzip everything , make sure you followed instructions to Mod out LGUP

step 2:

choose the system.img file from the zip

and flash it with lgup

pick the Partitions dl option in lgup

allow time to flash

on reboot pull battery reboot to recovery...

and do factory reset.

PROFIT.

your device has now been rooted.

if your satisfied with your rooted device please remember to donate.

Thanks

I'm with Videotron Quebec, Canada. I didn't adjust anything.

Just noticed flash and camera don't work..is it because I didn't factory reset ?

update: after reset still no camera and flash. This is interesting though.. I have a software update ready to install :) The 10c ..not the latest 10f. Should I try it ? I have a feeling that this one is still "rootable"
[General Topics] Chekm8Qc:
[MENTION=8236433]Astr4y4L[/MENTION]

bah tried the update lol didn't let me go through with it because of root :) right now I'm stuck with no camera :\
[General Topics] Astr4y4L:
Maby side-load adifferent camera app?

you are rooted after all...

don't have an actual K4 to mess with wish I did. !

Next I'm going after the older version of the Lg Rebel
[General Topics] Chekm8Qc:
yeah maybe .. Just installing another camera app doesn't work. I'm back to stock for now.

What would probably fix everything is to have that same system image you sent me but unrooted. That would probably allow me to go through the 10c OTA update. Afterwards depending of that update..I may be able to install root myself.
[General Topics] Astr4y4L:
WOWZERZ !!!

Nobody's ever asked me to unroot....

should be simple though...

and then you could update to the c version of software....?

and re-root?
[General Topics] Chekm8Qc:
[MENTION=8236433]Astr4y4L[/MENTION]

Yeah reroot but not necessarily with rooted img method. Depending if the C update is rootable .. It's kind of a guess. I'm confident that the ota would fix the camera though.

I tried updating with Lg Bridge from your system.img but the updater would have sent me back directly to 10F.

Unless your able to use that 10C firmware I sent u to create a rooted system img lol but damn I would be asking a lot.
[General Topics] Astr4y4L:
Kingroot = camera exploit

I do believe unless I am mistaken that Kingroot exploited a bug in either media stagefright.

Or

Camera....

Many u try and let us know if camera works before and after rooting the OTA.

Also what's to stop

Fota from downloading all the data to update clear up to newest versions. ..

Hmmm...

Worth a try I guess.
[General Topics] Chekm8Qc:
[MENTION=8236433]Astr4y4L[/MENTION]

Right now I'm on 10F though and Kingroot doesn't work I tried many times hehe. Like I said to update to 10C with ota I would need to be on your 10b but without root for it to pass.

So once on 10C my plan was to try Kingroot like u said, or there are other ways using download mode with sendcommand.exe (which didn't work on 10F)
[General Topics] Astr4y4L:
@Motojunkie01

have you by change got the firmware for the lg rebel

LG REBEL™ LTE (L44VL)

I can not seem to locate that.

---------- Post added at 12:00 PM ---------- Previous post was at 11:54 AM ----------

download mode with sendcommand.exe

was'n't aware of that one...

but kingroot will probably break your camera again...

i'm going to flip a zone3 over to K4 later this evening and i'll play with the camera and let u know what i find.

is it possible your download got corrupted?

let me see if i can get camera on one on my end...

i never really checked camera... was chaseing the GSM- dream Lol

Bout ta flash over to the kkgimage and see if its hard to unroot
[General Topics] Chekm8Qc:
I'm sure you know this but simply uninstalling supersu isn't enough I tried. LG has a root checker built in or something, once rooted it stays identified as root.
[General Topics] Astr4y4L:
Right

Ill unroot.

Dump the system partition .

Mount it in linux and replace both the RCT binary and rct log.

No big deal.

Then flash it back and should be unrooted

And pass that check too.

;)
[General Topics] Astr4y4L:
[MENTION=7110888]Chekm8Qc[/MENTION]

[General Topics] Chekm8Qc:
[MENTION=8236433]Astr4y4L[/MENTION]

damn that's interesting :) Things might have changed since 4.4.2 KK though. I will give this a try .. going to flash the rooted system img to start with. I will tell u about it as soon as I can :)
[General Topics] Astr4y4L:
@Chekm8Qc

the other thing you can do is first flash the stock .kdz from the F-version of the firmware

and then

flash the unrooted B-version of the system.img

reboot and done..

but do adb-backup first...

I'll have you a link to the unrooted system.img soon as done uploading.

that's the only sure method I know...
[General Topics] Chekm8Qc:
That would be great hehe
[General Topics] Astr4y4L:
So It's uploading steadily with Rsync over cable connection to sat-link,

should take a hour or two maby 3 but connection is very stable...

slow but steady...

I get like 12Mbps Down

1.2Mbps Up

So yea !:good:

but I'll send ya the link soon as it completes sync....

wouldn't want ya to get a partial and end up stuck with the brick ...

;)
[General Topics] Chekm8Qc:
[MENTION=8236433]Astr4y4L[/MENTION]

ok cool tyvm, I'm confident this will work. Like u once said, theres not much risk of a brick if it's just system img..I have my 10f kdz ready to fix whatever happens.
[General Topics] Heimish:
Can't you just flash original firmware and download and capture the update zip file?
[General Topics] Astr4y4L:
Yes but with out flashing the 121B the best kdz we got on k4 is 121F which is unrootable...

however if you flash a kdz you replace the RCT in the process.

then flash the unrooted .img and ota should work....
[General Topics] Astr4y4L:
Hey in the mean time can you confirm if this works for you:

first while on stock unrooted good RCT

please connect to PC and issue

adb pull "/persist/rct"

adb pull "/persist/rct.cfg"

and save those for a bit.

flash to the rooted system.

firstly download Rom tool box from playstore

next place those rct files we pulled from stock above in your sdcard

(just get them back on the device)

use rom too;box to replace the files in

/persist

and then full unroot from superuser app.

when it reboots it should catch the files you replaced that hven't been tripped.

and since you unroot from superuser it should go fine.

IMPORTANT ALSO REMOVE BUSYBOX BEFORE UNROOTING.
[General Topics] Chekm8Qc:
how do we remove busybox ?

I like the idea of pulling the files though hehe.

---------- Post added at 04:25 PM ---------- Previous post was at 04:11 PM ----------

@Astr4y4L

so adb pull didn't work... gives me persist/rct does not exist.
[General Topics] Astr4y4L:
Hmmm...

oh well was worth a try,

shouldn't matter

and remember the steps

first using partitions dl flash .kdz selecta all flash

then flash the unrooted UNZIPPED system.img

reboot should be good.

let me know

---------- Post added at 10:48 AM ---------- Previous post was at 10:37 AM ----------

edit

don't worry about busy box if youre flashing unrooted just flash kdz, flash unrooted system,

factory-reset to get the arm to odex,

roboot call it good...
[General Topics] Chekm8Qc:
yep will try thx :)

I might try to pull those files again once on B ..might work.
[General Topics] Astr4y4L:
yea it wouldn't do any good on pulling those from b, they would have been tripped if it was rooted.

Without root it's not going to show them...

I am going to find where they are in the rom eventually and make something kool to bypass rct for ota's in the future...

Just cause lg sucks for adding another layer of bs to our stuff.

Yep just flash all in lgup partitions dl then flash unrooted after booting once from stock and it should clear up if not im gonna throw a phone at the wall...

Lol
[General Topics] Chekm8Qc:
[MENTION=8236433]Astr4y4L[/MENTION]

damn I was sure it would work .. somehow detects .sh

Did everything like I was supposed to .. flashed unrooted image and factory reset. To start with I was on 121F official unrooted. I don't know what's wrong :( I didn't try the ota cause Im pretty sure it won't go.

I read somewhere that newer phones have RCT embedded inside boot.img

[MENTION=8236433]Astr4y4L[/MENTION]

man I hope the C firmware really is rootable lol .. If it works first thing Ill do is dump the system img of 121c with partition DL to finally have a stock C.
[General Topics] Astr4y4L:
absolutely and then upload to googledrive and link me in Bro

just sent new link for system.img unrooted

deleted

/system/bin/.sh

---------- Post added at 12:48 PM ---------- Previous post was at 12:34 PM ----------

another idea if new system.img gives error...

use rooted img

let it download the update.

go to adb shell

su

cd /cache/fota

ls

THIS SHOWS THE DOWNLOADED PACKAGE.ZIP FILE FROM OTA

dd if=/cache/fota/(NAME-OF-ZIP) of=/sdcard/update.zip

THIS SHOULD COPY THE UPDATE TO YOUR INTERNAL SDCARD AND RENAMED IT TO UPDATE.ZIP

exit

exit

NOW BACK TO WINDOWS COMMANDPROMPT

adb pull "/sdcard/update.zip"

THIS PULL UPDATE TO FOLDER YOUR WORKING CMD-PROMPT OUT OF....

NOW FLASH WITH LGUP USING FOTA UPDATE OPTION AFTER FLASHING .KDZ FIRST USING PARTITIONS DL OPTION TO ENSURE STOCK...

THAT HAS TO FREEKIN WORK

LOL
[General Topics] Chekm8Qc:
wow good idea man hehe

I'm at Walmart supposed to do the groceries but you got me obsessed with XDA lol
[General Topics] Chekm8Qc:
[MENTION=8236433]Astr4y4L[/MENTION]

ok so the new img still detects .sh

Going to try the rooted method.

update: so the rooted method.

When I type ls under cache/fota I get only a small 400bytes file called usd.dat.

I did transfer it to sdcard but I doubt this will do any good, when downloading ota it was 30mb.

damn I think I found it .. it was in data/fota named dlpkgfile

I now have a 30 mb update.zip on the root of my sdcard.
