Update: I tried flashing your bin with AsProgrammer V1.41 (got suggested for my chip Winbond 25Q128FV). On laptop #1, same as before nothing happening except for orange blinking charging indicator. However on laptop #2 white light on charging led when inserted then turns off, power button is lit up with a very dim light, barely visible and wifi-button glowing orange. I left it with the ac-cable in for a while then mute-sound button started glowing white. While it still doesn't boot that's giving me some hope....

Actually I'm sorry I'm just realizing the "original working dump" might not be "correct", I forgot to verify it before saving it. I'm not sure the importance of that, it's just that I just read somewhere that some chips should be worked on w a specific version of programmer, like 1.18 or something? Not sure how much lies in that though..

Didn't work unfortunately. Only getting a orange light blinkning blinkning by the charging cable....

I'm requesting a bios .bin for 2 of my hp Probook 450 G3's. Both of which I had forgotten the bios passwords. I stupidly flashed both of them with firmware "made" by the RCUnlocker software and I guess I shouldn't have. The last thing I did was flash both of them with RCUnlocker-fw thinking it would 100% work and left my programmer etc behind and won't have access to them for another 2 days so I figured I'd create a thread to see if I'd be so lucky that someone might have a working file laying around 😝
