hey everyone, today I found a way to bypass the lock screen and remove the password/ pin from the settings.
well, this i got to know accidently when i was trying to run a code on the phone.
hile i was searching on a sonymobile website, there came a code *#*#73556673#*#* to run the retail demo, after running the demo, my locked phone removed the pin and shown swipe unlock screen.

then i again locked it with password and then run the code from the locked screen through emergency calling number. after that i pressed the home button 2 times and my locked screen changed from password to swipe screen unlock.
NOTE that after pressing this code retail demo starts, and to stop that demo you have to run the code again....... if you want more help, then ask......

so this is easy way to unlock the Xperia zl, it must also work on Xperia z, if you have Z, then please share your views.

I think it is the best way to unlock the phone because it removes the password from settings. old trick was that to access the service menu through emergency number.........

my aim towards posting this trick was to show and tell SONY that they should look upon the security issues and improve the security for the upcoming updated of 4.2..........


please hit thanks if anybody was helped from this post

I work in a "Buy-Back" shop and a customer left his locked mobile with us, and then didn't buy it back.

This worked perfectly, and we can now re-sell his non-collected goods.

Just remember, after removing the phone lock, as OP says, input the code AGAIN, otherwise every time the phone goes into sleep mode, the demo runs.

Thanks OP, very helpful.

I quickly looked up and found this:

"Use SUS to delete everything on your phone
http://www.sonymobile.com/gb/tools/update-service/
http://www-support-downloads.sonymob...-2.11.12.5.exe - for future reference
Alternatives on How to backup Xperias

Looks like you'll need to format your cell phone.

Sorry for my late answer
however ... i solved my problem unlocking my bootloader
i've done it risking because i didn't knew if my bootloader can be unlocked or not but it worked and there was no loss of any data.
I don't know if this works on Xperia ZL but on my Xperia Z (C6602) it worked and also i'm not sure if this works on other Xperia Z phones.
Thank you anyway .
