LG Mobile Support Tool doesn't find my phone - LG Optimus G (International)

Hi, I want to downgrade my phone from 5.0.2 to stock 4.4, but LG Mobile Support Tool doesn't find my phone. Drivers was installed, I tried with download mode and it didn't help. How can I back to stock ?

There is an option "emergency backup". Otherwise, all metods include this programme earlier or later.

[F240*]Root your G Pro Kitkat!

Manual root method for Optimus G Pro(F240*)!
I'm not sure about E99* devices, but it will work, if it has same AP.
Just double-click Run.bat and follow instructions, and you'll be rooted.
P.s don't post this on Korean site Devoloid, LG Deivce World. I already posted.

Thanks OP! This works like a charm!

why recovery in this root is old ? how to update to latest ?
The Run.bat did not work for me because it kept saying adb.exe is not a command.
I solved opening a command window in the folder and following the run.bat commands manually.
worked perfectly

I rebooted in recovery after root, and I found the stock recovery again.
I assume this doesn't flash a custom recovery.
Just few questions: Will this root Optimus G Pro on KitKat only ?
I mean, if I didn't update and I were on 4.1.2, Could I use this root method to root my phone?
So if the answer at the previous question is a "yes" and since this root method is working on G pad and G2 too, Would it be possible to use this root method on G2 4.2.2 too ? Thanks.

Not sure about it, but both of them are possible, theoretically.
Any phone with system partition on /dev/.../msm_sdcc.1/... with stock recovery can use this tool.

No, you don't.
Just install it, connect your device with LG Software mode, and run update.
Note : updating your device will unroot it and custom recovery will be removed.

Did you select "apply update from adb" on recovery mode?
Yes, I did. After I selecting ADB, the bat file tried to send the zip to my phone but then there is a message, device not found.
I installed the LG driver and the USB driver from SDK tools.
I can see that Windows found the phone from the device manager but it is not installed properly. I tried to update the driver by pointing to the INF file in the SDK usb driver folder but still no luck.

I can root my phone finally. I just used a Windows 7 PC and it works. I only have the LG USB driver installed.

[Q] Software Update for Rooted LG G3

I have the D855 international, with v10f. It's rooted with PurpleDrake Lite. The phone has just downloaded a software update, which I have NOT installed. Can I install it? If I do install it:
- will I need to root again?
- will anything else be affected?

If you run the software update it will either work (and root will be maintained) or it will fail with a message that your phone is suspected of being rooted and boot back up unchanged. If it fails then you need to unroot first by flashing a KDZ of the version you are using in Normal Flash mode to retain your data/apps

You can try this method first to lose root and update your device:
http://forum.xda-developers.com/showthread.php?t=2797190
If not, you can also follow this guide to flash your current .kdz file again and lose root like that.
http://forum.xda-developers.com/showthread.php?t=2802286
If you want to find your current .kdz file, you can use this link:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI HERE
You have to put in your IMEI after the "=". That will take you to a page with some info. Use the link next to "<sw_url>", copy it and that will start the download of your latest rom (in form of a .kdz file).
(Not sure if I pasted the links in the correct order, but the first one should be regarding the use of LG PC Suite and the second one about flashing .kdz files)

(Q) easiest way to root this phone

Hi
I'd like ti root my phone and i saw few different ways such as "stump" and "purpledrake"
Which one is the better choice?
Thanks
Stump root, it's literally an app that you install, and click root

Stump root (like cliff said) or towelroot.
Towelroot may not work on all models though. It did work on my D850 with firmware 10D.

Well, this is untethered root, so it doesn't have a root app, so I recommend installing supersu from the play store, and supersu has an option to unroot, but there is always the option to just flash back to stock using a tot file or kdz file and LG flash tool

Not too long, if it is more that 10-15 mins, check your md5s.
Btw, 30e zips where filled in the same place, you can keep root if you root 30D, install twrp, then install new zips.
