Up to now, the ONLY one so-called "fw dump tool " I use is Hex Workshop!
You just peek into the *.exe flash programs,
extract 2048KBytes from the programs and save as, say *.bin,
then, most important, ADD .CVT Header ( 36 Bytes ) to the *.bin,
and the checksum ( 4 Bytes ) to the end of the *.bin file,
then, rename it to *.CVT,
then you’ve Got it!
This method can be only applied to those firmwares before B2I7 and B3D7.
As for those FWs after the above two,
BenQ has EnCrypted the FW, and it’s hard to be extracted, but NOT Impossible.
I used SoftIce, found that is was devided into 0x80h pages, 0x4000h Bytes per page.
Then, use some memory dump utility to dump all these pages and then combine all of them into one *.bin file.
After that, as before, add Headers and checksum to the *.bin files to make *.CVT files
But, these *.CVT files have not been tested…
Yes, there indeed is a DOS Flasher.
Come with the package of Philips 8301 Flash Disk, for HP 300c OEM Model,
You can download it from below…
But, maybe it will also check for HP DVD-Writer… :a
