[Q] Rooting The O4X-Questions - LG Optimus 4X HD

So I'm getting my phone shipped now and was wondering a couple things about rooting. I've rooted many times on previous android devices but none were as locked down as the O4X... I already looked at rooting guides here on xda for the device but i was wondering will i be able to root on any O4X firmware or is there a specific one you can root? For Ex: v10c, v10d etc... or can all firmware #s be rooted? Also if i root on stock fw and get the OTA RootKeeper app and then update will i maintain root?

V10a, b, d, e and f can be rooted if I remember well. Even the V10g beta can be rooted.
Root goes away when flashing through the kdz updater.
Factory reset doesn't delete root. I don't know what an OTA update does with root, but I think root was kept anyways. If root disappears after an OTA, just root again. If that fails, rollback to an older FW with the kdz updater and root again
Rooting for the LG is quite simple, but be sure the phone it's USB mode is in Charge Only. And factory reset after root is advised.
If you brick the phone, reflashing it with kdz updater is easy.

[Q] LG-P880G (Canada | Wind Mobile) Update V10F

As of 14 Jan 2013, the current version of the Canadian firmware has gone from V10C to V10F. I have no info on new benchmarks (if any), but I can confirm that V10F wipes out #ROOT / Super User access, and cannot be re-rooted (as far as I can tell) via:
qaz753's method
Root MANY ANDROID! method
.kdz rollback combined with either of the above.
It's entirely possible that I'm experiencing this because I'm a n00b, but I have attempted all three, all after hard-reset, without any success.
Quaz753's falls flat early on, when IS11LG_SystemBackupTest.signed.apk installs, but crashes at startup.
RMA method "fails to mount" in cmd and asks "are you [ROOT]?
And you can't roll back the firmware: when attempting, the device freezes on a black or grey screen, but behaves completely normally as if nothing had happened after a reboot.
So, now, are others experiencing this?
Has anybody gotten further than me with the aforementioned methods after the updates?
Or do I just wait until someone smarter than me writes a new rooting tool?
Any updates on that?
EDIT: Yup. N00b here. I was forgetting to replace the battery when the firmware downgrade began. That fixed the rollback to 10C, and then "Root Many Android" worked just fine
*** See my post below for the step-by-step for upgrading to V10F with #Root. ***
EDIT 2: Here is a new link to V10C Firmware: Dropbox
Like you, ive flashed to the new firmware and both rooting methods youve mentioned has failed. I have reverted back to v10c to get root back, getting a little tired of this phone.

Have you tried doing a FOTA with OTA Rootkeeper and temp-unroot? For me I could always do that, and root was restored once the firmware upgrade process was finished.

Can you (or anyone else) please confirm that you followed the following steps:
Obtain #Root on your LG P880G Phone, Firmware V10C using either of the methods above
Install "Voodoo OTA RootKeeper" (Sorry, too new to the forums to be allowed to post a link to the PLAY store)
Run RootKeeper, and click "Protect Root"
Still in Rootkeeper, click "Temp. un-root"
Run update via LG's stock "Software Update" app, upgrading to firmware V10F (FOTA: Firmware Over-the-Air)
click 're-root' in RootKeeper
So that you are now running V10F with #Root and all is well?
I don't want to be the guinea-pig for this, just because my wife will yell at me if I get caught doing another factory reset
Thanks!
EDIT: This method is confirmed as working. See my post below for the step-by-step for upgrading to V10F with #Root.

Sorry, I forgot to write that I don't have a P880G, but a normal (german) one. But why do another factory reset? KDZ flash doesn't delete your data. With FOTA I mean "normal" firmware-over-the-air, with the integrated Software update app, without a computer or cable. That has never changed any data on my phone. I had to restore all the system applications bacuse it complained at first, but after restoring them and temp-unroot everything went fine and root was kept. But as said this is only tested for nomal P880. Can't tell if your G version uses some other methods which wipe away root. IF that's the case, I unfortunately can't help you.

If I wasn't clear before, I hope I can be now: I regained #Root after the Canadian (Wind Mobile) firmware update to V10F, but I had to use the crudest means possible. I am not an expert, but here is the recipe I used:
Section A
Back up EVERYTHING: contacts, app data, media, etc., and read all directions to the end before you begin any step.
Download the .kdz for V10C (If that doesn't work, here's another link: https://www.dropbox.com/s/nuccg8hu4p1495l/V10C_00.kdz)
Manually roll back your firmware using THIS METHOD (following each step very carefully, eg. replacing the battery during rewrite).
Obtain #Root using THIS METHOD.
The finished product: I am now back to firmware V10C, with #Root ...just like before you blindly allowed the FOTA (Firmware Over-the-Air) update V10F. What, were you hoping it was gonna be JellyBean? Now, for the update:
Section B
Ensure you have #Root on your LG P880G Phone with Firmware V10C using the above steps
Install "Voodoo OTA RootKeeper" (http://play.google.com/store/apps/details?id=org.projectvoodoo.otarootkeeper)
Run RootKeeper, and click "Protect Root"
Still in Rootkeeper, click "Temp. un-root"
Run update via LG's stock "Software Update" FOTA (Firmware Over-the-Air) app, upgrading to firmware V10F. Do not use the LG Desktop App.
RootKeeper automatically re-enables #Root
The finished product: I am now upgraded to firmware V10F, with #Root.
Thanks to muellersmattes for proposing the method in Section B, and to tnsantos, thanson, and laskaca for confirming this method.

Section B
Obtain #Root on your LG P880G Phone, Firmware V10C using the above steps

So, to Recap:
If you are using the LG P880G, and follow Section A, all will be well.
If you attempt Section B, please report back with your findings, as I am eager to hear of your results. Oh, and please be sure to "Thumbs Up" all of the linked posts above if you use them.

This works fine for me.
I installed v10b brazilian firmware and rooted it using Bin4ry script and then I followed your tips and now I have v10c (latest brazilian firmware) rooted.
lg p880g upgrade to v10f still root by using your method
thanks alot
Root P880G 10F
As mentioned before tested with Idea to use Root Keeper. This was the brightest idea , so
1. Downgraded my P880G to original 10C software using KDZ.
2. Rooted with Root_with_Restore_by_Bin4ry version from 13.09.2012
3. Used Root Keeper to backup root
4. Used Root Keeper to temporary unroot the phone
5. Updated phone to 10F by lg update app
5. Restored root backup in Root Keeper
6. Root access is working perfectly fine on 10F firmware
I would like to say BIG THANK YOU to muellersmattes for this idea.
PS: Phone is LG Optimus 4X HD LG P880G Canadian version of LG P880
After more than one hour trying to aply this methode to Brazilian V10C, I gave up...
Still without root access

Maybe because I downgrade to V10A... its the only reason I can see.
Tried all possible ways to keep root access but didn't worked, at least for me. Like I said, maybe because of the version
Now its too late, I'm half way to have the official V10H "adjusted"
Thank you anyway

I'm sorry.
Step 7: Update from v10b to v10c using OTA Update. If you flash v10c kdz you will loose root.
obs.: v10a doesn't have OTA Update. You have to flash v10b kdz and do this procedure. It will work, I'm using a v10c rooted

Just for the sake of clarity, this thread is about dealing with the current Canadian firmware issues. I request/recommend starting a new thread with the same format as this one for Brazilian/European problems.

[Q] rooting 4.3 w/ locked bootloader

so iflashed .534 firmware ang root using vroot then i update .290 via OTA, now the root is gone. my bootloader is locked.
im kinda nervous rooting 4.3 cause im reading lots of people hard bricking their phone on 4.3. is it really safe to root 4.3? i will be followibg this tutorial:
forum.xda-developers.com/showthread.php?t=2572988
Hard bricking happen when you do something stupid. Also in general there is a Thread How NOT Brick your Phone. Anyway, to get root you have to downgrade again to .534, I recommend to root with Bin4ry, then update directly to .136 with instructions given by NUT Here. You cannot keep root updating system via OTA, you will lose everything.
clicked Thanks

[Q] Root for 4.4.2 KitKat firmware on SM-G730W8?

I was wondering if it was possible to root the kitkat firmware (NF2) for the SM-G730W8. I'm worried that I won't be able to root it because KNOX might prevent rooting. And if i do install the firmware i won't be able to go back to 4.2.2 because of KNOX. If anyone has been able to root it on the newest firmware please tell me.
*Update* i just flashed the firmware and i was able to successfully root it using Towelroot. Unfortunately there are lag issues and the touchscreen is really glitchy when playing games like Dead Trigger 1 and 2 and MC5.
I was able to root this phone using a trial of Chimera Tool.

Help rooting?

Hello all,
Im totally confused as to how to go about rooting my device c6902. Ive owned a couple of android devices and Ive rooted them all, however....with this device and there seem to be different ways people have rooted from reading the threads and im totally confused, So far I have unlocked the bootloader, and upgraded the device OTA to lollipop .242 (before the bootloader was unlocked), I dont intend installing any custom firmware, just want root so I can use TB and maybe delete a few bloatwares with root explorer and use xposed.
Im confused as to whether:
1. I have to downgrade firmware to kitkat, just to get root, then upgrade back to official firmware?
2. Ive been under the impression that a custom recovery and supersu, is enough to get root. It doesnt work that way on this device?
3. I saw some oneclick root programs that worked on the z1 compact would any work here
Just trying to know more about the phone and understand, so any help is appreciated. Thanks in advance.

Using the guide on the link I just posted, you are not required to unlock the bootloader, unlocking the bootloader without backing up the TA partition can cause problems with your phone.
You need to downgrade to KitKat 4.4.4 with kernel 108, then root it with easyroot install supersu and rootchecker to make sure your phone is rooted, the use NUTs recovery to create a recovery partition, after that search XDA forums for a pre-rooted lollipop flashable zip and install that, and voila you should be on lollipop with root and recovery.
I am not sure about one-click root programs.

I already unlocked the bootloader though. Do I need to downgrade the whole kitkat rom or flash just the kernel? thanks
Figured out. Thanks

If you want root down the road but aren't ready to root now

Would it be wise to update past 11g on tmo LG g6?
In other words can the LG g6 be downgraded
Thanks!
I've never heard of a way that you can downgrade without root, especially with fastbpot commands being removed. Root requires TWRP and I believe the latest firmware that has been confirmed rooted was 11G. If you ever want to root, I wouldn't take the upgrades.
You can always flash the 11g kdz if the anti rollback number is the same
