[Q] How to check if the phone is unlocked?

I'm getting a used Nexus 4. I'm new to the phone. So how can I check whether it's unlocked or not? Thanks!

If you mean sim lock then all Nexus 4s come sim unlocked. If you mean the bootloader then reboot the phone and if it's unlocked then an unlocked padlock will appear beneath the Google logo on boot.

Thanks a lot for the kind help! Yes, I meant to ask the bootloader unlocking. Sorry for the dumb questions:
What does the unlocked padlock look like?
Can I root the phone without unlocking the bootloader?

you cant miss it, its at the bottom of the screen at the google logo, looks just like a padlock. if it's still locked, nothing will appear at the bottom, only the google logo in the center.

It looks exactly like an unlocked padlock Once you get the phone it'll be pretty obvious. No, you can't root the phone with a locked bootloader but being a Nexus device it's trivial to unlock it. Check out this guide, it has everything you need to know.

Really appreciate everyone for the great help! Going to play with the phone tonight...

Bootloader Status Check

How can we know if the bootloader is locked or not? Is there a way to know it through adb or through a secret code?

It's only "locked" on 900V and 900A (Verizon and AT&T) variants. Other variants are not locked nor lockable.

Thanks, but without having that information how can we check if the bootloader is locked or not?

I thought I was clear, sorry.
If you have the Verizon or AT&T version, it is always locked. If other version, it is always unlocked.
There are no known ways of locking or unlocking the bootloader on a Samsung device.

Thanks again. I already know that besides Verizon and AT&T, all the versions have the bootloader unlocked, but is there a way to know that through adb or a secret code? i.e. If Knox is 0x1 we realise that the device has been rooted, likewise, is there a way to know if the bootloader is locked?

i have its gotten me nothing so far

in retrospect
I just got my hands on one of these and I'm not sure if the bootloader is locked or not I did a procedure that leads me to believe it is. I am not 100% sure though, and since I am not really a noob, nor of a minor tech, I understand the importance of being 100% certain.

What is the model of the phone according to the phone's screen in download mode? What is the boot loader version?
These two items will help you determine whether the boot loader is locked.

All Canadian Note 3

Does this "Unlocked bootloader" apply to all Canada versions of the SG Note 3 N900W8 as well? Thanks in advance.

I am unable to boot into bootloader on ATT model :/

Lol as expected from Sprint and AT&T. Dont get me wrong, i wish they had bootloader unlocked because the more bootloaders unlocked for different carriers, the more chances to duplicate the amount of developments/roma/mosa/kernels etc.... Now, having only Tmobile as the only one with unlocked bootloader, well, devs who use carrier such as AT&T and Sprint might get further away from developments on LG V20. (I'm a LG V20 Tmobile variant owner)

im not to familiar with LG, but the correct way is to power off the device, hold volume down, insert USB cable?
one would think even if locked, it could still enter the bootloader. adb works, and when i reboot recovery, i get to recovery, but when selecting reboot bootloader, the device starts. interestingly enough, it will enter in adb sideload mode

With Google obviously not wanting unlocked handsets or rooted handsets to be common... This kind of thing is going to be the norm. Best to adapt, in the long term. The days of modding are being ended by Google

I would agree if not for the fact that the pixel phones can be unlocked

For the time being. As SafetyNet gets more common, Google will quit making them unlockable.
Granted i preordered my v20 expecting to run it unrooted stock.

Well, it's really only sprint, at&t, and more than likely Verizon. Fastboot mode doesn't even exist on the phone through the production software. T-Mobile is completely unlockable...

So this means no recovery for sprint variants, but is there still a possibility of systemless root using the LG up or bridge programs?

According to twitter there is a root being worked on by chainfire unsure of whether or not it will be for all variants or just unlocked bootloaders

T-Mobile is rooted because of bootloader unlock v.v not the other variants.

So the root chainfire has established will be tmobile only?

He said it was based on jcadduono's work and if jcadduono has a thread on here about getting root shell to push recovery on the TMobile variant after unlocking the bootloader.

time to return it!

Just a thought. A method over use getting around big red in the past . I purchased unlock able version of the the phone I wanted the note 5 . Umocked it rooted it . Then got my carriers Sim card and called to get it activated. It can be a pain but it can be done

I thought since we had the "enable OEM unlock" option like T-Mobile we would be good to go.. smh

AT&T Bootloader Unlock

I'm considering getting a G6 from AT&T and I'm curious if there's any chance it'll be unlockable. I haven't had an unlockable bootloader in three phones now and really missing it.

yeah you can count out on that on ATT\ VZW

count out on it = you'll probably never see customs roms or recovery

"count out on it" is a confusing way of saying 'no'. but thanks for the response. this is sadness

It shows that I can unlock my G6 from the developer menu like you do for the Nexus devices. I haven't hit the button yet since we don't have TWRP or Root.

But if you run
Fastboot oem unlock
It won't work, most likely. All phones have that option

Would be worth a shot. I have the option on my S7A but I don't have proper fast boot because Samsung <.<

IF it does get unlocked and rooted ill buy another.

Not sure why so negative. The LG v20 is currently being supported by team lineage along with older g5 g4 g3 g2 and older LG tablet. For the price the G6 is going for right now on at&t half off this month only I'm certain this is the best time to get in on new technology that's currently missing from my G3

The zero development for this device is why I'll be going back to HTC with the U 11.

the 870 bootloader was just unlocked by LG.... hopefully they follow history and unlock the US version next (870 is European I believe)
Greg

Let me know. LG-H871

I wish my h871 unlocked

ATT VoLTE and relock bootloader?

Before I get this phone. Does anyone on AT&T know if they white-listed this device for VoLTE?
Also, can we re-lock the bootloader like Nexus Devices or once the bootloader is unlocked it can never be re-locked again?
Thanks

You can relock the bootloader if you want to unroot and return to stock.

Thanks I posted the question there..as I did not get a definitive answer. When I say relock, i want the behavior like the Nexus phones where it will do another wipe after the fastboot lock and fastboot mode shows correct lock status. Used to have one plus 1 and once unlocked you could never relock the bootloader..

AT&T only supports VoLTE on AT&T branded phones. So unfortunately, no.

par for the course w/ that company. I think they have taken the mantle from Verizon as being the biggest jerks. If it wasn't for their iPhone business, they'd be sunk. They have done a fabulous job of raising the prices of all things DirecTV too. ugh.
