I noticed there's a lot of unlock request for this model HP ProBook 455 G9
The patch won't work if the bios version is latest. use this bin flash both it won't work if you only flash the main you should Flash Both.
first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
use BCU and put your original DMI.
frequently asked questions:
can i use this to my HP ProBook 455 G9- yes
This is the both BID U78 and U88 its all you need.
This bios main is from official website then added VSSTORE and patched...Last edited by rex98; 06-30-2025, 08:40 AM.Leave a comment:
