I forgot my screenlock code

[MasterWayne]

Hey there,

I have a huge problem, as you might have already guessed from the title.

I put in a new screenlock code for my xperia v yesterday evening, went to sleep and forgot it.

I already tried to update my software via PC Companion, but it says, that i need to unlock my screen to gain access to my phone.

I also tried several system codes like *#*#7378423#*#*, but these also don't work.

I don't want to do a hard reset either...

Can someone help me please? 😕

EDIT: afaicr it was a 4 digit code with no 0 in it

But wait...it's a simple software update O.o Why should that erase my phone memory? I updated my phone sowtware a couple of months ago and everything stayed where it was 😮

This is reinstalling,it will erase the memory.

Oh...okay ._. 

Thank you very much for your advice
