Factory reset and do it again.

Good morning from germany...

I done all the things. Before that i uninstalled apps like Avast Mobile Security and such things.

Especially the things you marked red.

I don´t have made a full wipe, because i don´t want to lose all data. :)

But maybe the following lines help.... thats the output of root.bat.......

* daemon not running. starting it now on port 5037 *
* daemon started successfully *

DON'T TOUCH THE DEVICE OR UNPLUG WHILE ROOTING!

I think i will wait for the next BIG Uptade from LG before i full wipe reset my LG4x...

And then i hope the root will work again....

At this time the LG apps suck the power out of my akku. :/

Try to search for the folder "eu.chainfire.supersu", should be in "device/data/data" and delete it.

In folder "device/data"local" you should only have the folder "tmp" and inside of it the file "init.rc", other files, if you have them, delete.

After this, try to do the ROOT procedure again, better to re-install the drivers to the latest:

Phone acting slow. After about 10 minutes I rebooted the phone again myself as nothing was happening (acting slow still). Tried SuperSU but it says no binary installed. So clearly it hadn't roted.

Uninstalled the IS11LG_SystemBackupTest.signed.apk and tried reinstalling it, but it crashes on launch now every time I try.

What the hell am I doing wrong!??!
[LG Optimus 4X HD] RuedasLocas:
Factory reset, re-try all the process.

After you hit enter to "root" in cmd, the busybox and supersu will be installed, and phone will reboot 2/3/4 times, depends...

After it stop rebooting alone, you need to see if you have SuperSU in your apps.

If you got root, do a factory reset to wipe root install files.

hi!

thanx for your support.

but i don´t find any of the folders or files.

I find the "init.rc" but in the root of the telephone. i think that was not the right on.

I now have factory reset my handy and root it again. the rooting was quickly enabled and works.

[LG Optimus 4X HD] Ben-B:
Barclays online banking app doesn't work on a rooted phone due to security checks :( I use that quite a bit as I run my own business, so I may unroot just for that reason. I've tried apps to remove unwanted startup apps etc, but haven't noticed any change in battery life. So the only benefits of a rooted phone to me would seem to be - restoring complete phone backups (ironically I would never have needed to call on a backup if I hadn't have needed to factory reset to get root!(And of course couldn't as it wasn't rooted then!)) and Ad-stopping.

Perhaps I'l unroot after all that time spent rooting and setting the phone back up!

You need to do a "factory reset" after root.

You should pay atention to the tutorial.

Is slow because of the install files, after factory reset it will be normal again
[LG Optimus 4X HD] Mardinio:
How can i do a factory reset? Is there a way to do it outside the phone? or a shortcut or something? my phone does absolutely nothing but show the background.

Also i just did this :: Install "IS11LG_SystemBackupTest.signed.apk"

Open the "SystemBackupTest" app you just installed.

Hold the power button and choose "Power off and restart".
[LG Optimus 4X HD] RuedasLocas:
to factory reset...

take out the battery, it will go off... put it back and with the phone off, press "Vol-" and "Power button" untill it turns on.

It will turn on in Android recovering system, select factory reset and use power button to confirm, next select wipe data and power button again.

after select reboot and power button to confirm and its done. It will reboot normally.

Would appreciate a reply at the earliest.
[LG Optimus 4X HD] alekthefirst:
I would suggest using titanium backup

If you are going to freeze apps you will need the pro version
[LG Optimus 4X HD] kelly66:
Thanks. Does freeze mean temporary disabling while delete means permanent removal (delete allowed in non-pro version)? BTW, which are those apps that we can delete/freeze?
[LG Optimus 4X HD] RuedasLocas:
Freeze means that the app won't start at all untill you unfreeze it.

Delete will remove completely.

Depending of if you have or not a backup, you'll be able or not to re-install deleted apps later.

To have some kind of advice about which apps you should delete/freeze, search "battery drain" threads.

Well didn't work for me as phone frozen and ended up on factory reset BUT strange thing is before I had no options under call setting to block people, few mire settings were missing, since factory reset my phone now has these features and turns WiFi off when screen off also battery improved dramatically.

[LG Optimus 4X HD] RuedasLocas:
Like in any handset, the ROOT access allows you to manage your phone more freely.

Maybe you need to install a specific app to install apps in sd card, but you'll need root access

for several other things like, un-install stock apps or apps that allows you to un-install/freeze them.

Most apps require root access to be installed too...

For those trying to root with non V10D_00 firmware.

Hi guys!

Recently I was trying to root a friends LG 4x from Claro Puerto Rico (firmware V10b_00) we couldnt root the device because the "IS11LG_SystemBackupTest.signed.apk" would force close ( Unfortunately SystemBackupTest stopped working ) when opening it. What we did was the following:

1. We downloaded European version of the firmware V10d_00 from here :http://lg-phone-firmware.com/index.php?id_mod=15

2. We flashed the new factory image to the device following this guide: http://xdaforums.com/showpost.php?p=32683265&postcount=3

Notes:

In step #1 from the guide it uses V10F_00, keep in mind that we will use V10d_00 so replace it in the steps needed. In step #4 in the "Select Type" drop down we chose "3GQCT - SmartPhone(WM) (our device is in a GSM network). In step #6 we can infere from the OP that the battery was removed previously. So we removed it right after powering it off in (Step #5).

Process takes a bit to complete so dont get anxious. Also, we got an error about not being able to create a log file. it didnt affect our process. The device will restart all by itself.

3. After we flashed the firmware some stuff started to force close so we did a Reset/Factory Default from the device (this went pretty fast).

4. Now that we have installed the firmware version needed for root we just followed the root instructions from this post http://xdaforums.com/showpost.php?p=29866696&postcount=1 .

Everything worked like they said. Make sure to follow every step like they tell you to!

5. [Optional but recommended] If you want to install Clockworkmod Recovery just follow this guide: http://xdaforums.com/showpost.php?p=30057690&postcount=1 and Voila! Rooted 4X with Recovery.

In our case it was a win-win situation since our stock firmware was behind the new one (V10B vs V10d) in your case you might go backwards. user tnsantos claims he was able to update the firmware while keeping root. Personally I did not test this but its worth a mention.
