Thanks to all
Hi..This is a little HOWTO i managed to bypass wireless whitelist on my HP Compaq 6730s which has efi bios and uses HPQFlash with ROM.CAB file.
Few years from now i did similar thing on my HP dv2320us (dv2000) which used WPH in combination with Winphlash so this is little diffrent. Why am i mentioning this..? Because i used combination of two.
http://www.bios-mods.com/forum/printthread.php?tid=5577 and previous knowledge.
1- Extract spxxxxx.exe, then extract ROM.CAB
2- Open Rom.bin with Andy's tool (PhoenixTool from phoenixtool185)
3- Once decompress, select "other" in manufacturer
4- At advanced choose: 'no SLIC' and 'Allow user to modify other modules' press done
5- Press GO and wait until the tool pauses and show popup (Don't press OK at this time).
And now comes the "hard part". I copyed the DUMP folder to my Linux box and used some scripting to find my original because there are A LOT of files in a DUMP folder.
I used something like
Code:
for i in ./*; echo $i; do hexdump $i | grep "14e4 4315" > log.txt
after that i surfed through the file and concluded that there are 4 files in which my wireless card is repated.
My original Broadcom card was
14e4 4315 137d103c in windows device manager and
e4 14 15 43 3c 10 7d 13 in hex editor
My intel Card is
168c 001c 10261a3b in windows device manager and
8c 16 1c 00 3b 1a 26 10 in hex editor.
so the files in which i located my card were:
233DF097-3218-47B2-9E09-FE58C2B20D22_2_815.rom
53984C6A-1B4A-4174-9512-A65E5BC8B278_1_803.rom
5EE86B35-0839-4A21-8845-F1ACB0F688AB_3_335.rom
F6D35FBB-63EA-4B25-81A5-5E62B4886292_3_178.rom
do in each of them there were two "lines" i edited:
first i replaced e4 14 15 43 3c 10 7d 13 with 8c 16 1c 00 3b 1a 26 10
and
e4 14 15 43 3c 10 7c 13 with ff ff ff 11 00 00 00 00.
Why this? Couse when i calculate the strings that i ended 555 + 556 = 1111 with the string i wanted to enter 328 was 1111 - 328 = 782 which is decimal of "ff ff...."
I don't know if this was necesary but i wanted to calculate the checksum allone..
that was for my part. Now i finished the previous tutorial with jumping to number 8.
8- Press OK on Andy's tool popup
The Andy's tool will notice about changes that were made and will reintegrate the module.
I rebuilded ROM.CAB with CABPACK (cabpck14) and flashed it with patched HPQFlash (HPQFlash_4.30.10.2_patched).
And it WORKED..!
