My phone htc is locked I have forgot my four digits code

some common default codes
1234
0000
last four digits of phone number

defalt phones codes is 12345 or 00000 u can use it
Default 4 Digit user code: 1234 or 0000
Default 6 Digit Security code: 123456 or 000000

remove and reinsert the battery, press and hold the volume down then press and hold power, you should be in hboot mode, press power once, you should see factory reset among the options down, scroll to it and press power. Note: all data will be lost.

Most phones the security code is the last four digits of your cell phone number. If that's not it, try dialing *288 and pressing 1 when promted. This will reset your phone and then the security code should be the last four digits of the phone number. This is at least the case with MOST cell phones. If not, bring it to the nearest store location of your phone provider and they can reset it
Hope this helps

Try four zeroes. Otherwise, your options are pretty much limited to a brute force attack or a factory reset.

did you try the last four of you number

Providing you have not changed the code since purchase, by default the 4 digit code is set to four zeros(0000)

did you try the last four digits of your phone nimber or 0000?

what you can do is press ##DATA# (##3282#) then go to ADVANCE, VIEW, and last LOCK CODE..... there you go now you are able to see the lock code in which your for is currently on!
