How to unlock phone (locked after 5 PINs attempts)? - Xperia Z3 Compact Q&A, Help & Troubleshooting

Suddenly my phone get locked after 5 incorrect PINs entered (were input by mistake in my pocket?). The phone shows error msg with Sony logo saying that I have 5 attempts and 5 attempts used. It also has some input field, but my PIN code is not accepted (just nothing happens, no any new error msg). The phone is rooted. But I want to recover this particular setup with all data, apps and its settings, corporate certificates - don't have recent backup .

Was it a phone pin or sim pin?
If the sim pin fails it will ask for a puk code. You need to call your carrier to get it.

This is not quite clear from the message (it says about PIN code, graphic key), but I think this is not SIM lock, since when I made recovery, it doesn't require any PIN.

Cant remove PIN

Hi!
I have a weird problem.
I have tried to remove the pin code on my device but i always get wrong pass/code.
I can change the pin OK, but cant remove it.
Even tried entering it three times to get to the PUK code, entered that one and changed pin. But still cant remove it.
So annoying to enter the code every time the device boots.
tried to uncheck "require pin when phone is used"
in settings phone ?
Yeah, thats when i get "Warning : Invalid old password. Please try again."
Same problem here. I'm unable to remove the pin code.
I unchek "require pin..." type my pin to validate and always get wrong pass/code.
Can anybody help me?

Changing Pins

How do I find out what my PINs are? I'd like to know so that I can change them to my own personal numbers. PIN 1 (Phone) says there is only 1 attempt left and I've never even tried to access it to change it. PIN2 (Sim Card) says there are 3 attempts left and again, I've never tried to access it.
T-Mobile's Technical Support say they have no idea what they are.
Anyway to access this information so that I can find out what they are?
Thanks.
Well, to no avail I SIM locked my phone. lol. I ended up having to call T-Mobile and request my PUK (Pin Unlock Code) to unblock it. Apparently, each and every SIM has their own unique PUK so what your PUK # is won't work for someone else.
SHOULD you ever happen to fall in to the unfortunate event that I managed to do just call your service provider and request the PUK #.
There are different steps to unblock phones on different services.
My service provider is T-Mobile, USA, and I will list the PUK process to unblock your T-Mobile service phone should you ever need it.
Request PUK from T-Mobile customer service.
Unlock PIN code (PUK) (when PIN is entered wrong 3 times) **05*PUK*NewPIN*NewPIN#
If nothing happened after pressing the "#", then press send.
e.g. **05*XXXXXXXX*NewPIN*NewPIN#

need help unlocking focus flash, sim error

I didn't see a focus flash forum and it is very similar to the focus s internally so wanted to try posting here. I just got a focus flash from ebay as well as an unlock code and put my t-mobile sim in the phone. However, when I enter the code and tap enter, it says "sim error". I can cancel the unlock prompt and go to the metro ui, and there's a little sim icon with a lock on it. If I take out the sim card and restart, instead of the unlock prompt, I get a little box that says "sim error" and a message about missing or invalid sim. The little sim icon at the top has a little (/) instead of a lock. What could be the problem? It also says no network found in the cellular section of the settings.
same issue
i am having the exactly same issue with my focus flash, can any one help ?? and if the op user found out the solution please share
How many times have you tried to enter the unlock code? Id used to be (and probably still true) that trying more then five times will lock your phone permanently. You should get back to the person who provided the code and inform them of the issue. Double check your IMEI number when you contact them. One wrong digit in IMEI will generate a wrong code.

[Pin Security] 10 Strikes & you're [wiped] out

Can this be disabled?
Kids could easily do this by accident or even someone having a laugh.

The PIN code is on the SIM card, not the phone (you may already know that) - the phone itself doesn't know your pin. The phone sends the PIN entry to the SIM card and the SIM card will either say "Accepted" and unlock, or it will fail and remain locked.
After 10 (usually) failed attempts, the SIM will lock itself. You can Unlock it by using the PIN Unlock Code (PUK). This is NOT the PIN code, it's called a PUK code. You may be able to obtain this code from your carrier / operator.

How to acces the IMEI of a locked (pin) phone (huawei P30)

Detail at the botom
-Is it possible to acces the IMEI of a locked (pin number) phone without wiping it (physically or with a computer) when the SIM tray is lost
-Would a phone connect to a new sim card without loging the pin number and if so, is there a way to sand a message to the owner of the phone that way? (automatic picture entering wrong pin number?)
thanks!
I found a huawei P30 in the snow, still working, sim card tray was absent. The phone is locked with a pin number and won't connect to free wifi so the owner as no way to communicate/locate the phone. I tried to post of local facebook, called huawei to help locate him, but nothing worked so far. I think i will have to wipe the phone to get the IMEI and then see with phone enterprise if they can send a message to the owner but ideally i would return the phone with all is data....
So i was wondering if there is a way to aces the IMEI number. physically or with the help of a computer or alternatively, if by putting another sim card in the phone, the owner would receive a notification with the picture of the person holding the phone (which i could do with contact info) or something of the like.
thanks all!
