How to find right BIOS version: https://www.badcaps.net/forum/troubl...flash?t=122195
In short for the 2nd guide: search for $BID with hex editor
What you need is BID 088BC, HP for whatever reason mixed BIOS updates for AMD and Intel on the same page, you have to expand the category "BIOS-System Firmware", then "HP Notebook System BIOS Update (Intel Processors)" , the other BIOS updates under "BIOS" category are for "HP Notebook System BIOS Update (AMD Processors)"
Of course you shouldn't flash a BIOS for AMD CPU on an Intel CPU laptop (yours is Intel)...
The correct BIOS is sp163283.exe
Run the .exe, It will extract several variants, yours is 088BC.bin
DMI is empty on yours (no model name, SKU, build ID, feature byte), it only has a Win key, is it a replacement motherboard? I transfered it anyway, you should fill the rest with BCU
Here it is, with your Win key inserted
HP Pavilion x360 Convertible 15-er0077nr (33K64UA)
BID 088BC
DMI 500000-50103F
BIOS ver. F.28
Fill the rest with HP BCU
Additional info: sp163057.exe extracts fine on my HP laptop, it extracts 088F1.bin but it isn't the correct BIOS for you anyway (it's for AMD CPU, Ryzen 4000 series - Renoir)...
When you can't extract an HP BIOS update, you can try running it on a virtual machine
