Forgot pin password

[Missproblem]

I have an LG marquee phone and it had a pin password. I have not used that phone for a year and I had an urgency to unlock it, but I forgot my pin password. I tried 10000 for digit possible combination but obviously I used more tha four. I also tried to go to boost mobile provide from where I got the phone and they told me that if they do it it will erase all the information, but I need those voice memos which are on the phone. I cannot use unlocking through my gmail account because phone does not have Internet acces and I also cannot plug it to the PC because it won't recognize it, I did not changed the settings on the phone for it to be able to do that. I also checked SD card which I had on the phone but my voice memos are not saved up there. If you have any other idea how I could unlock my phone by not deleting my voice memos. Please help!
