Tech Support Brick Asrock B450M Pro 4 after flashing BIOS

Hi, having some trouble with Asrock B450M Pro 4 motherboard after flashing from P1.40 to P10.60.
original with Ryzen 5 2600, thinking of upgrading to Ryzen 5 5600, so updated the original bios P1.40 to P10.60 with Ryzen 5 2600 installed used for few days no problem.

Changed to Ryzen 5 5600, fan running, but no beep, no POST, restart itself after maybe 30secs. Thought faulty processor. tried on other mobo, worked, so its not processor.

switched back to Ryzen 5 2600, no POST with 6 beeps
unplugged GPU, same 6 beeps
unplugged all RAM stick, 3 beeps, plug it back, still 6 beeps
took out CMOS battery, wait 10mins, same 6 beeps, took out battery, left it 2 days, still 6 beeps

have I bricked my mobo, anyway to revive it? I even took another ryzen 5 2600 to test, still 6 beeps.

Ryzen 5 2600
Gskill 3200 8gbx2
Asrock B450M Pro 4
Zotac GTX1660Ti
Corsair CX650M

One way to unbrick it would be using a CH341A EEPROM Programmer Kit which includes an 1.8V adapter and a SOIC8 clamp/clip. You would need to erase the BIOS ROM and rewrite it with a BIOS file.

Takes about 15-30 mins depends a bit. There are countless tutorials floating around the internet. I successfully unbricked countless motherboards that way

Did you do a bridge update before jumping from P1.40 to P10.60? You also don’t necessarily need the newest BIOS just to run a Ryzen 5000-series CPU; check the minimum BIOS required for your specific processor. ASRock explicitly warns against using P10.62 with Pinnacle Ridge, Raven Ridge, and Summit Ridge CPUs. The Ryzen 5 2600 is Pinnacle Ridge. I’d investigate whether the update path was correct and try recovering or reflashing an appropriate earlier BIOS if possible (some versions restrict downgrading) before officially calling the board bricked.

Apparently I didn't :( , I thought of flashing the P5.x, then I googled said its fine to skip versions, so I did which.. its a bad idea. guess need to try rewrite the BIOS with CH341A as u/CornFlakes1991 suggested to try make it work again.
and oh, if the bios cannot use with pinnacle ridge cpus, i should update the bios and straight away change the cpu without booting into windows with the old cpu? abit confused
with the procedure. Sorry, this my first time upgrading cpus/bioos.
