nope, the A15 didn't work at all using this method for some reason, i downloaded the A05 bios on dell website then extracted the .fd file and renamed it to M17R4.hdr, after that I created a bootable fat32 USB using Rufus and copied the hdr file on it.

 

you put the usb in a normal port (not the e-sata) i used the port on the upper right side, remove the battery and power cable, now hold 'END' and while holding put back the power cable, keep holding for like 4 seconds then let go.. 

your fans will go loud and after a few seconds the laptop will start beeping really loudly for several minutes (that's totally normal, let it beep) eventually your laptop will restart and become unbricked.

 

that's basically it.

   

A brief update: thanks to you suggestions, I managed to downgrade from A15 to A05 using a normal USB port. After that, I succesfully re-installed Windows, then gradually upgraded from A05 to A15. This resolved my 1beep error.

hello everyone, my m17xR4 BIOS got bricked (1 beep) , and i tried the method exactly as it says but the screen just stays dark and no beeps, fans are loud though, i waited for 30 minutes.

 

I tried almost all BIOS versions.

 

im suspicious about the M17R4.hdr name , maybe my laptop doesn't recognize it for some reason. 

any ideas?

thanks 

 

EDIT: Nevermind, I got it fixed.

 

if anyone's interested, it worked on the USB port not the E-SATA. also i formatted the USB drive into a bootable drive using Rufus, that's it.. hope it helps

Hi,

I'm nearly in the same situation. Have you used the A15 bios for the installation?

Dear @Klem,

first of all, thanks for your assistance with our old laptops. I need an unlocked A15 bios for my m17xr4, could you please unlock it for me?
