HP Probook 4520s Administrator password reset

[tietoharrastelija]

Hi,
got HP Probook 4520s laptop. Works ok, but can't enter bios because it asks Administrator password. Boot from HDD or USB is allowed.

Tried:

HPBR - Result: Not supported notebook
FPTW - Can dump but no re-flash... (Error 280 Failed to disable write protection for the BIOS space)
SMC.BIN (HP no longer creates these files)
Short Method: https://superuser.com/questions/1108...30s-reset-bios (Not worked)
RCUnlocker (Created unlocked file from bios dump but can't flash with FPTW (error 280)

I don't have hardware / SPI flasher.. Anyone can help? Is it maybe possible reset admin password another way?

Product number: WT152EA#UUW
Serial Number: 2CE0380ZRD
UUID: 2EDCE21E25C7DF11BD47E080B300006F
