[Q] Stolen phone

Hello,
I would like to ask if someone steals my phone and hard resets it or something, can i locate it myself?

no you can't..

Here is the best guide i have seen as regards security.

It will only protect your phone in case of a normal reset, if somebody manages to completely wipe/ flash a new rom you are done for. Still following the guide heightens the chances you will get your phone back.

Factory reset - Problem.

Greetings everyone!
Few weeks ago, I gave my device to a friend of mine to manually update it. Something went wrong so he decided not to go any further. Yday i tried to "Factory reset", after reset some error pop'd in the left upper corner of the phone.It says:
[LGE_SECURITY] ERROR: boot image signature
Critical failure: Unable to start kernel.
Unrecoverable bootloader error (0x00000002).
Anyone had any similiar or even the same problem as i am facing right now? Thanks in advance.
best regards, Milan

Guy didn't know what he was doing apparently. Your handset is still locked and he apparently tried installing a 3rd party ROM, lemme guess, you wanted a newer version of Android than 4.1., which is a reasonable enough thing. Problem is that out of the box you can't do that because it only boots images signed by LG and they abandoned development after releasing 4.1 and a couple of minor point releases. You aren't totally screwed but if you were having somebody else do it for you, you might need to get some help. You can find the details elsewhere here, or more likely point a more skilled friend at it, but here it is in a nutshell.
You need to get LG's official updating software (from the LG website) and you need to fiddle with it a bit until you get it to do a rescue because it expects to have already paired up with the phone while it was still working. If you already had it installed, great because it will make it easier. Anyway, you will probably have to manually pick your model and input the IMEI since it won't already know those things and it will go out and fetch the most recent image. You will push VOL Down and insert the USB cable from a powered down state, it will then do the rest. Good chance you will even retain your data unless that 'factory reset' you mention actually succeeded.
Of course that will only get you back to stock 4.1. Read around for the official way and several un-official ways to unlock your boot loader. Once that is done you can install a better recovery and then a newer version of Android. But the first step is to restore the stock software since you have to have a running phone to be able to unlock it.
And no, nobody has ever been able to explain WHY they lock them, but every single manufacturer seems determined to do it, chipmakers put a lot of work and ad copy into how extensive and unbreakable the locks on their newest chip is, etc. And then they either bow to customer demand and add an unlock feature or we here at xda do it for them... as a courtesy of course. Truly we do live in the asylum. Wonko the Sane was onto something.

Lock Pattern changed on its own, help sought as no longer able to unlock phone

Hi all,
Greetings first as this is my first post on XDA and appreciate all you guys contribution all the way through here. Back to the topic I got my X9 using in good condition unless of low remaining space yet some weeks ago during my normal use the machine suddenly froze and reboot and after that though I am able to unlock on the first boot screen, by using the same unlock pattern I cannot enter my desktop and it always tell the pattern is incorrect. Yet no matter how many trial I did it didn't force me to exponential-time-wait. I googled for some time and learnt that the same problem happened on samsung S7 and some nexus device (those HTC made ones?) So at this point I am wondering if:
- there is any chance I can unlock my phone without data loss? i tried "find your phone" on ADM yet over-riding lock screen seems no longer work;
- The machine is clean as-is from the factory without any s-on/off or unlock of bootloader; under current circumstance am I still able to install TWRP and get a back up being dumped? (seems I can dump a copy and use the pc script to look into the gesture-key, or simply delete the gesture.key from TWRP / aroma manager);
- Any other alternatives I can do? I really want to keep the data inside as there were some precious photo as well as some chat-record that is not being backup to the g-drive;
thanks in advance =)

Zuk Z2 Pro password locked

Wonder if anyone can help? I have a 3 yr old phone that I put a password on and cannot remember it. I haven't used if for two years but thought I would have a mess around.
However I am stuck now. Is there a way of overcoming this somehow. I still have the receipt from when I bought it. Any help or guidance appreciated.

Hi Hi,
it would be the easiest to make a factory reset, so all your data and all your locks are history...

Thanks for the reply. I ended up reflashing a stock ROM, upgraded to Android 8 and changed the launcher. Tried AOSP 10 ROM but couldn't get on with it.
I did try to factory reset but my phone wouldnt allow it. Seems it is not as easy As it seems.

OK, without that you have been dealing with the material in the last few years, it seems a lot.
But the STOCK ROM is also good enough and should be enough.
If you want to update to Androi Q you have to read into the material with the various TWRP and factory / vendor partitions, but this has been discussed far too often, so there are corresponding threads.
Good luck, and if you don't need your Z2pro anymore let me know )

Click to expand...

Look in 9 pro forum. I think an adb command can remove the pin code via bootloader.
But this is frowned upon bc you may have stolen a phone etc.

I think that stopped working a good while ago.
If you forgot your PIN only option is a full phone wipe I'm afraid.
