1. You need a good hexeditor
2. Download the firmware of your choice
3. Extract the raw image from the firmware using GExtract
4. Find what you want to change
5. Make a vkp-patch file. File format explained below.
A vkp-patch file is as follows
;Everyting with a ";" infront of it is just text
;W800 SW-R2AB123 (nice to let ppl know which firm the patch is for)
;Here is a description of what it does
;some more instructions
;Maybe a warning if one is needed
;© afghanjohnny (or you if you make a patch)
;this is the flashbaseaddress. Where the first byte of the firmware will be flashed.
;Check GSlide for your firmware.
+44020000
;The first text-field is the address in hex of the first byte which will be exchanged, it's ended by a ":"
;The first text-field address is the same as the offset in the file.
;The second text-field is what the original bytesequence is
;The third text-firld is what you want GSlide, GFlash or FAR to change the second text-field to.
;The second and third text-fields must be the same length!
;All bytes is in hexadecimal.
3DDB9A: 6900660073002F00730065 7400700061002F00750000
;A second patch is here, much shorter this time.

My recomendations is to study patches and the addresses in the firmware already done and then try to apply it to your own firmware. Or if you have a new idea, try to implement that. :) :) :) :) :cool: :cool: :cool:
