bootloader in ICS is locked. Nothing to do about it, for now... later we'll see but, once in JB I don't believe
that someone wants to remain or go back to ICS.

Ok..tnx for clear answer
First welcome to our forum , I hope will find what you need .
Why do you want to know 'how to check' .
It's locked in ICS , unlockable in JB (for devices are EUR-xxx ,, after flash JB see the software info in settings) .
You can check it by :-
Code:
adb reboot-bootloader
Fastboot flash kernel xxx.img
Then you will get an error says :- error partition is locked .
Update your phone to JB and then unlock it , then check it in the hidden menu (3845#*880#) , goto bootloader status (or something like that) then will see it "unlock" (of course after you unlock it) .
About check them in recovery (like HTC devices) , in LG you can check them in download mode , you will see "unlocked bootloader" in the corner of screen .
to get any help we are here and you can ask us as much as you can .

Try roll back to v10h(if that is your latest stock for your phone before official JB update), than use LG Mobile Support Tool (official) , and try to flash your phone with "recovery phone" option in Customer Suport menu in LGMobile Support Tool!
And if you didn't before, try first to use reset and clear cache partition from recovery!
(Make backup of important stuff ..apps, pics..)
Or try to wait a little longer than 30 sec next time..

Some new info about unlocking from LG:http://forum.xda-developers.com/showthread.php?t=2224020
Hi,
I've got the international version of the Optimus 4X HD, bought online in the U.S.
It has been recently updated to V20c - the software version code is P88020c-AME-XXX.
Can I use the same unlock procedure for the EUR-XXX models, or do I need to flash EUR-XXX before attempting to unlock?
I had no troubles rooting the phone by following the instructions in this thread.

EUR-XXX worked for my ESA-XXX. It will work for you, if you have bootloader unlock check in hidden menu. You may have fastboot problem, so be ready with correct driver and correct method.
Refer to this thread if stuck on red colored Download mode for long time and no response-

Alright, thanks for the fast response.
The hidden menu indeed has the bootloader unlock check.
I'll report back once I try it.

Hi,
I have absolutely no idea on android so need help. I have purchased a faulty Moto G (dual sim) 2nd gen and it just gets stuck on the blue moto logo screen (powered by android) for a few seconds then just switches off. I can get into the recovery screen but that's about it.
Any help would be hugely appreciated.

If you have not done anything to the phone, like trying to unlock the bootloader or things like that, then yes, just return the device, you got a bad apple.

It is repairable but if you still haven't unlocked your bootloader then you can just get repaired free of cost from the service center but if you decide to do it on your own, you'll have to void your warranty in order to do that!

If you bought the phone second hand and have no chance of getting your money back then you can follow these instructions.

Just beware that unlocking your boot loader voids your warranty.
I think you should seriously consider just doing a factory reset on your phone.

Moto g 2nd gen stuck in boot
Hi everyone,
Sorry for reviving thid thread. I have a moto g 2nd gen with unlocked bootloader status code: 3, it wont go past the boot animation with the globe and Motorola logo then shuts off, screen turns black with faint backlight and i have to press the power button to completely turns it off.
What i did so far.
I booted into recovery and made a cache and data wipe, didn't work.
I flashed a stock firmware. (5.02 btw) through fastboot with bootloader relock, all steps were successful but same result, wont go past animation boot.
I noticed when i issued bootloader lock command, log says successful but bootloader is still unlocked.
Also noticed phone is not detected by my pc except in fastboot mode.
Any help will be much appreciated.

Ok so I just upgraded to android 11 and want to unlock the bootloader but while doing it through the app it says failed to unlock the device why is that?
Also I have never unlocked my device before it's the first time I'm trying to do so..
Do a backup of your data you don't wanna loose and flash raw file with A10 available here in ROG3 section. Then your unlock tool will work. After you unlock you can update and restore data. Bootloader remains open until you lock it again with abd or app.
