How to reset LG Optimus 3D P920 Android
If the phone is frozen, you may then try to hard reset your LG Optimus 3D P920 through button combination.
1. If your LG Optimus 3D P920 is frozen, turn the Power OFF, pull out the battery and reinsert it back again.
2. Hold the Home and Volume Down button
3. Press and hold the Power button until the device turns on, then release buttons when LG logo appears.
4. Follow the on-screen instructions on how to reset your LG Optimus 3D P920
Wait 'till the process finish. Once the wipe is complete, the phone will reboot to its factory fresh default state settings. All data you previously installed on it already been deleted.
Privacy > Personal data >Factory data reset – Erases all your personal data from internal phone
storage, including information about your Google account and any other accounts, your system/application data and settings, any downloaded
applications and your DRM licence.
Resetting the phone will not erase any system software updates you have downloaded or any files on your microSD card, such as music
or photos. If you reset the phone this way, you will be prompted to re-enter the same information as when you first started Android.
If the phone does not respond to user input, or the screen freezes: Remove the battery, reinsert it and switch on the phone.
or
You can use LG Mobile Support tool to repair some LG cell phone model, after download select menu Customer Support > Recovery Phone
Thanks for the update.
One dealbreaker for me is the hdmi audio problem discussed on the o3d forum.
so you dont need to reapply the baseband?

Hello all,
I'm new to android phones (my first one) and I didn't find the answer to my question.
I wanted to update my unbranded Optimus 2X (Germany; V10C, 2.2.2) and the software under Win XP ended up with an error message and had to be closed, while updating.
When I start the LG2X now, I only get "S/W Upgrade Please wait while upgrading...".
Now I could jump into the recovery (Power + Vol. down) and after pressing the home button I got into the menu of the Recovery Utility.
I can scroll between the following options with the vol. up and down buttons:
- reboot system now
- apply sdcard: update.zip
-wipe date/factory reset
- wipe cache partition
Unfortunately I can't confirm any of those options. Nothing happens when pressing the power button. The home button hides the menu and all other softkeys are without function.
Can anyone please tell me how to do a factory reset now? I'm all new to this stuff.
The man from the support, who should collect my phone, didn't get here today, like it was announced by LG support.
Thanks in advance for any suggestions!!!
Best regards from Germany

Use that to factory reset instead.
OR
Use Smartflash to do the flash the debranded ROM, that should function fine as you have to boot into software update mode anyway.
Thanks! Smartflash did the job! I can use my P990 again.

I think, your phone is hard bricked.
If at least phone turns on, you can try Rewriting IMEI process, then problem will be solved.
Take some developer's advice and confirm the device's problem will be solved or not.
If not, you have to go to LG service center.
You should NOT check erase entire (what it now is)

(Sorry for my eanglish)Hi gyus. I broke ma phone, but not totaly. I just want to install cyanogen, so I do much things on phone, but all of my guides are in Polish. I can paste it here but i don't think it will be helpful. So I install revowery TWRP from XDA using aboot v10b when I have v10f system and flashify, but i can't install CM. So i downgrade my system to 10b and than i install recovery. Showed up purple screen, so I turn phon on in download mode and by LG Mobile Support Tool I install oryginal system. Now I can use phone, but I cant go to recovery or do factory reset. When i wan't to do factory by kesy combination vol- + power i can see "Factory Reset Processing..." and after that only black screen. When I wan't to go to recovery by flashify I can only see

5) Send e-mail to [email protected]
What I must to do now?
Like you said:
"LG Mobile Support Tool I install oryginal system"
If you flashed the KDZ with LG support tool you don't have a custom recovery now, so your phone doesn't boot to it because it's locked.
You must root, unlock bootloader and install a custom recovery again.
my phone screen is purple with a written white letters: "DBI Apps Watchdog Reset" among other writings as well. What I have quefazer to be able to use it again?
My mobile phone is a L40

Hi good day everyone!
Need help for my P880 bought last 2yrs ago, here's the errors I got...
1. First, like in a computer program "deep freeze" every time I install/uninstall any apps then reboot or just a simple restart, it comes back in his default settings.
2. Second, when I try to install any apps suddenly this error appears "Unfortunately, the app has stopped". After that it restarts by himself.
question is... what should I do now?! any suggestions please
3. Third, when I try the "soft reset" in settings> backup&reset> factory data reset> reset phone... Yes, it restarts after that nothing happens.
4. Last I encounter this error too "Inconsistent UIDs"
I put some vids..
link: https://www.youtube.com/watch?v=tckBX5Mp8K4&feature=youtu.be
So what I did is...
1. I tried the hard reset (push and hold Vol- and power button) nothing happened... Even I tried the all combination buttons.

link: http://www.hardreset.info/devices/lg/lg-p880-optimus-4x-hd/
2. I tried also the flash S/W thing with battery, HOLD Vol- then put the USB cord. It stacked in the middle of the process. I did without a battery but only black screen I got.

3. I bring this phone to LG support center and they said it has a defect motherboard, and I need to bring this in LG main branch which is miles away from my place... fffffffffffffuuuuuuuuuuuuuuuu
when i open it it stuck on lg logo
i can't access recovery mode (i don't know why
when i make factory reset with the buttons in the phone ,after i check (yes) 2 times and apper the green broken android it;s show lg logo and stuck again
so what i do in this case???????????
You could try either flashing the .kdz file or try to press Power button for a few seconds on the broken android and see if it works.
*pull of your battery an then press all buttons you can find for about 3-5 seconds.
After that reboot your phone.
If this don't work
*There is a special program from lg, you can find this at the official website.
The only thing you had to do is:
1) install the drivers for your phone
2) open the program and connect your phone
3) if the program locate your phone you have won
4) select that you want to Undo update Errors and wait till finished
This are the solutions I used with my D405
