Hello,

a friend did brick his Acer Aspire 1652WLMI
The recover with Crisis disk and bios.wph file failed.
Is it possible, to convert a wph file to bin? :roll:

With an bin File I'm able to remove the FLASH Chip, reprogram and replace it

Unfortunaly new BIOS is also an wph file :evil:

thanks Ger@ld

Hello,
I had a similar problem with an Acer Aspire 3000-ZL5, all you need is an Hex Editor. On Acer Support website there're 4 BIOS updates, 3 for laptops with ATIs Graphics Card and 1 more for Intel Graphic Card, versions 3A43 and 3A45. There are 4 files available, the size of your Firmware chip is 512KB (7FFFFh starting from 00000h). Open the WPH BIOS file that corresponds to the graphic card installed in your laptop with your Hex Editor and go to the file position 80000, erase everything from that position to the end, you should end up at 7FFFF if done correctly, nothing more nothing less than that. At file offset 7FFF0 it should start with byte E9 xx xx than in these versions should be E9 3F B4. Save the file with a different name or overwrite it and you'll end up with a file size of 524,288 bytes, once you check this you're ready to program your chip with this file. Very simple.

Hi drgn997,

I've found the same way

But unfortunately is my english not so good, to tell, what I did :oops:

I tested two ways:
At first I take a backup from my Award BIOS with WinPhlash (Phoenix flashtool) and again with Winflash. With Award BIOS files I'm familiar :wink:

So I'd found it.
To verify, if it's right, I did this modification with the original wph file and did open original wph and this new rom file Phoenixeditor.
Bingoooo! Phoenixeditor can open both files without error

A good question is, for wath is the rest in wph? Maybe an image from NVRAM :?:

Or informations about flash-algorythm? In HEX-editor be some chip names visible...
