Optimus 4X HD Root and Unroot - LG Optimus 4X HD

Hi guys. I have Optimus 4X HD with latest update - V10f. I will want to root phone and use NFS: Most Wanted Mod to play game with less lag (at this time game lagging heavily some times). I have three questions:
Can I root V10f with thread I found without any problems (http://forum.xda-developers.com/showthread.php?t=1818502)?
Can I update rooted device, if any update will show?
Can I unroot device later?
Thanks!

If you read the threads then you should already know the answers. You can root and unroot, but you may not get OTA updates, although if you do then you should keep root.

[Q] Lost root after update :(

I know I am not the first but I was running Shift3r rom, flashed back to stock, ran the official 5.5.893 update and now I no longer have root. I tried the one-click for3v3er root but it didn't work. I realize I should have done the for3v3er root first but got ahead of myself. My question is: Is there anyway to regain root access with the new official update yet or do I just need to sit back and wait for one of the awesome developers to come out with one?

[Q] How to perform OTA 4.2 update to a rooted Nexus 7?

I am very sorry for what is certainly a stupid question, but if it is any consolation I DID search and read through threads until my head hurt prior to posting.
1) What is the best way to apply the new OTA 4.2 update for those with rooted Nexus 7 tablet.
With the 4.1.2 update, I blindly installed the OTA update when prompted and didnt realize there was a problem until i tried to access my stickmount USB drive. Luckily the nexus 7 was still unlocked so I didn't need to wipe everything. All i did was re-root it using Nexus Root Toolkit v. 1.5.4. and was back up and running. Is this going to be the same experience with the 4.2 update?
I have installed Voodoo OTA Root keeper v2.0.3 - is this a better route for upgrade instead of re-rooting via the Nexus Toolkit? And if so, how should I use it (do know much about the app).?
2) Is stickmount going to work? And if not, is there a good working alternative for streaming mkv h264 movies to MXPlayer (or other player)?
The main reason I rooted was to access a USB drive for playing movies, TV shows while traveling. We are heading off to Cabo for Thanksgiving and definitely want to be able to access and play movies from my stickmount'ed usb drive. Any suggestions ? Should I just wait to update - and if so is there any way to get the Nexus to stop prompting to install the update all the time?
Thanks in advance to anyone willing to have pity on me...

1) I just downloaded the OTA 4.2 .zip, copied it to my N7, ran CWM and flashed it. When it asked about keeping recovery and keeping root, I said "yes" and it worked without a problem!
2) Works for me.

Sorry these answers need to be dumb'd down for me
1) If i already have the update downloaded via OTA trying to install itself, is it really easier/necessary to locate the zip you mention, copy it to the N7 (not sure where to copy) and run CWM (not sure what that is or where i get it or how to install it). Is there an easier way to accomplish the update? Perhaps setting the Voodoo Rootkeeper to preserve the root or temporarily unroot.. then just install the downloaded OTA update and then return the root? Or just installing the update and then running the re-root using the Nexus Toolkit (like I did with the 4.1.2 update)?
2) I would like to know more about how you avoided this issue described in this thread here with stickmount not functioning with v4.2 because of the new mulituser framework that causes it no longer to see files in the mounted folders.
Thanks for your help and to anyone else that chimes in... any help is appreciated. Again sorry for being stupid.

i tried with OTArootkeeper app. but it don't update.... at restart for installing, it gave a black screen with android in the middle, with a RED icon inside it...... then it restart and 4.1.2 is always there
Perhaps these questions are so rudimentary that they hardly seem worth bothering with - but for some of us, these hacks and the info being thrown around in here are pretty confusing at times. I would be very grateful to anyone with some insight willing to help out?.
i found that this could be a problem with recovery mode... infact if i tr y to restart in recovery, it gave the same error...
i rooted with toolbox, and i'm thinking that it could have removed my recovery... now i'd like to try to recover the stock recovery with the same tool... but i'm not sure about that.
We seem to have veered off topic a bit here (at least for me)... so let me re-post the questions and beg again for mercy from any kind soles who can offer some advice?

Bueller...... Bueller...... Bueller?
Hi! Last month I did the 4.1.2 OTA update. I was rooted but on stock. It updated with no problems. I used Voodoo OTA rootkeeper, restored the root, and either renistalled super su, or just updated the binary. Can't remember.....But I did lose my custom recovery. Didn't realize it till tonite when I went to do the 4.2 update.
So to your question. I forced the OTA 4.2 update. And it downloaded. I made sure voodoo rootkeeper was set to save the root. Then let it install. It rebooted. I opened voodoo, restored root, was asked to update super su binary, accepted. Still not rooted till I rebooted.
So far I have root, and am on 4.2 JB. So my goal was to get my custom recovery back on. Install goo manager from market. Open it, go to the settings button top right, it will give you the choice to install open recovery script. TWRP- Then it will ask you twice are you sure you want to do this and reboot? Say yes. Mine did not reboot and it looked like it did nothing. So, I flipped into recovery and Teamwinn recovery was installed. I made a backup, and rebooted.
Good luck!
Thanks for your help. Glad to hear that the OTA 4.2 update should go relatively painlessly (keeping root using voodoo rootkeeper). If you have a minute, I would be grateful if you can just briefly confirm, describe specifically what I need to be checking/configuring in Voodooo (not very familiar with the app) prior to initiating the OS update, I would feel a little more secure before pulling the trigger.
It appears that many apps are still catching up with their own updates, including apparently stickmount (the reason I rooted) to handle the new 4.2 framework so I am thinking best to hold off until after thanksgiving vacation before applying the update.
Thanks again.

Hi hinsdale,
Have you tried updating to 4.2 yet? Also i heard that if you update SuperSU to version 0.98 the latest version it could cause issues and you will have to reflash the device.

4.2 OTA already loaded, lost root
Hi, I have learned the hard way not to do the OTA upgrade. I just let the 4.2 OTA download when asked to. Now I lost my root that I had on my Nexus7 with 4.1.2. Still unlocked though. What can I do now to root it again and not lose all my apps and data?
I'm a newbie, so please remember that when responding. Thanks.
Hi hinsdale! I am not a techie- I just learn as I go and read, read, read.
So, my voodoo app has 4 checks in the boxes. I seem to remember only 3 boxes checked when I did the update, but I'm not sure. It would make sense that all are checked.
After I updated, I opened the voodoo app first, and there is a box that says restore root. Then it asked if I wanted to update the su binary. Did that, still not rooted according to Tit. BU. Rebooted, then I was rooted. Good luck with your update.
I'm sorry I can't tell you how to run the initial save root on voodoo. I did it a while ago and don't remember, but it was not hard. Very easy.. Just make sure you Read, re- read, and read again before you do any modifications to your tablet. Know the possible bad outcomes, and be prepared to trouble shoot. This site is very good about helping you out if things go wrong. That's why it's a very good idea to be aware of the possible bad outcomes. The only way to know is to READ-READ=READ!
Did I mention READ??? lol. That's how I figure stuff out. If you read about others mistakes, you can avoid them. I also wait a day or 2 to see how it goes for others before I attempt modifications. That includes new roms. You never know what goes wrong until someone is the guinea pig! I am not techie enough to be the guinea pig!

same thing here...I tried to use TWRM to flash SU but it seems that after going into recovery using TWRM I can't see any any file or folder on my SD except 3 folders???? Can someone please help us....
YOu will need to search the best way to root again.
How did you root initially?? You may have to do it that way again. Just make sure the method is compatible with 4.2 JB.

Nexus Root Toolkit
The OTA update downloaded to my cache folder, I moved it to my sdcard. Wouldn't install since I had to fix a couple of files I had edited. So once those 2 files were fixed it installed just fine. Haven't had any issues yet.
The same on here...
But I guess it is better until they fix all this bugs they are reporting.
I'll wait until then.

Updated to 4.2
Hi have updated the nexus to 4,2 and used Voodoo OTA Rootkeeper to keep my root followed the instructions as I did when updated to 4.1.2,my Nexus appears to be rooted superSu is working also stickmount sees the usb but it will not show any files on the sd card any help here please to get it to see the files on the sd card, thanks for your time
Nick
i dont post often as i am usually here looking for help. this time i get to help
i just downloaded and installed 4.2 OTA.
if your nexus was previously unlocked and rooted, it will download and install just fine. however you will lose root, but KEEP the unlocked state.
to root it again, you must goto "about tablet" and tap your build number 7 times to become a developer, this is not a troll, i got this info from another thread on xda.
then using the nexus root toolkit 1.5.4 with modeltype set to "android *.*.* any build", just do the root procedure.
reboot and ur in business, no need to update supersu, and busybox will still be installed already.

[Q] ICS vs JB, should I OTA? root post OTA

Hi all,
Just got the A.HD. still stock ICS.
I've been reading many threads and Google searches since, and have a couple of questions....
I would like to get answers from people who have had this phone for a while and rooted and/or done the OTA update.
I've read several conflicting user reports about the JB OTA update.
Is there any real performance gain? I've read articles showing JB boots faster than IcS and has a better overall feel.
The only solid thing I've read to make me want to do it is the ability to resize widgets in JB.
I've used JB ROMs on my captivate glide and Acer a500 and didn't care for them; but idk if they were just buggy ROMs or what (never used stock JB)
1) so who would recommend the JB OTA update and why?
2) does the motofail2go root method work after the JB OTA update? If not, what does work to root the official JB?
Again, I've read conflicting reports and would like to hear from folks that have done it.
Thanks!
-Eric
Motofail will not work on JB.
Root ICS, then you have to do some things to backup root with voodoo root keeper and what not, then install jb then restore root.
Do it carefully I am now without root on JB because I didnt know what I was doing.
To answer your other question, I think JB is worth it but meh up to you.
i kept mine on ics because the webtop feature.....
i modify a cheap atrix 1 lapdok 100 and when im away i use and love it...
of course root it to get ride of the att junk and installed safestrap recovery to install other roms....
i will start shacking about update to JB when custom kernel can be flashed to the phone but who knows when is going to happen
Backup your root on ICS and update to jb. I love having the latest and greatest and jellybean is definitely another and has some nice features that I couldn't go without now. Just my opinion
Sent from my MotoAHD Maxx
I reccomend updating to JB. I have JB and root and I couldnt imagine going back to ICS.
If you do decide to update, just be sure that you:
1) Root ICS first using motofail.
2) Open Superuser, scroll left to the info tab, select su binary, select update, exit when it finishes.
3) Next, install OTA Rootkeeper from the Play Store. https://play.google.com/store/apps/details?id=org.projectvoodoo.otarootkeeper
4) Open OTA Rootkeeper and select backup su.
5) When it's finished select temp un-root, restore root, temp un-root, restore root. (I reccomend doing it twice as stated just to be safe.)
[IMPORTANT: Don't forget to update su binaries and don't forget to temp un-root and restore root. Do NOT update while temp un-rooted. Can't stress enough.]
6) Go into settings and download/install the JB update.
7) Once booted up and running JB, open OTA Rootkeeper (if it isn't still installed just re-install it) and select the first option. Something along the lines of restore su backup.
8) Once it is finished restoring root, if anything still shows up unchecked, exit the app and re-open it. Now it should all be checked. (At least that's how mine worked out.)
9) Download Root Checker or open an app that requires su to make sure you're rooted.
10) Enjoy rooted JB.

Thanx for the responses
one more q:
does anyone notice battery probs on JB.
on other two devices, JB custom rom was awful on battery... (again, dont know if they were buggy ROMs/kernels or what)
thanx again
I stayed on ICS. It seems a few things got removed on JB. I had started a list.
Do the battery mod man. Then you won't have to worry about bad battery life.

Re-root problem

Hi guys! I have a serious problem. Last week i unrooted my phone to win a bet. (Dont ask what sort of cuz i was drunk.) Now, when trying to re install root all apps i've tried (vroot, z4root and a couple of pc softwares) fail. I really need root. Although, z4root tells me theres an already 'su' binary installed in my phone and force unroot is available for me. But when i press un root, it goes to the loading screen then crashes. When i try to reopen it, it crashes suddenly. I have an LG P-880 a.k.a LG 4X HD. Please help me ive tried to factory reset it 2 times by now and a hard reset(whatever that means.... I've watched it on YouTube.) My question is: is there any program that can delete the su binary and all root stuff then re-install it?
Sir,
Please wait until mods will move this thread to the device specific forum.
For reply or more questions please register an account on XDA forums.
Stand by
Until then please read this guide: [GUIDE][ROOT] How to Root your LG Optimus 4X HD (O4X P880)
Good luck

Should I update to H1110n if I plan on rooting eventually but haven't yet?

Hello everyone. I got this phone about two weeks ago and it's been telling me there is an update available this whole time but I haven't done it yet. I've rooted an HTC One and an HTC Evo 3d before and I know in both cases there were times where taking an OTA update made it more difficult to unlock and root your phone. I don't know if that is the case for the G4 but I figured I would ask before I update. So, will taking the update affect my ability to root my G4 or is it safe to just do it now so I don't have to be worried about Stagefright? Thanks in advance for your help!
Root, twrp, update with the rooted n rom in dev section.

I successfully rooted and installed TWRP, CM12.1 on 81110n. So it's not a problem.
