But when i decompress original firmware with PhonixTool and then compress it back without changes everithink is ok ... flashing and startup bios.
for a complete test you must make a change, compile, decompile result, undo the change and compile again then you can compare to the original! note: I've just made this test above and the "redo" file is identical to the original one. The tool is not the cause of the issue. The following test may be helpful, changing a useless byte and see the result: in 5EE86B35-0839-4A21-8845-F1ACB0F688AB_3_155.ROM at address A00 change the "T" of the string "Text" to "t" , 54 to 74 in hexa. compile and flash. let me know if the machine is bricked again.
Yes it is bricked again... maybe i'm doing somethink wrong .. i open PhonixTool open original firm. bin file in advensed set to change other medule and no slic... then press go .. then in dump dir make changes and press ok in PhonixTool to recompile firm... everythink is correct? then put on dos flash with name 68DVA.BIN boot from flash start pached erompaq /! ... and then brick again... i check changing in comresed bin file with original ... it is changings comlicated because this module (recompressed) - maybe checksum for this module (5EE...) not corrected recalculated?
Just need find out ... what is the features (it is not bug) i start compare from model 620 (those in yours pached list 68PVI) and 68PDV from 625.. just need more time... (and need deasm erompaq 5.0Fa) to undestand what they calculate to permit flash bios.. do you have original version on erompaq 5.0Fa?
I am trying to use a new wlan card on my hp mini 5102. It seems HPQFlash (not patched version and patched version) not work for me, Can you PM me the patched erompaq? (I'm too newer to PM you ...)
I have written a wrapper to your code, and tried it on HP 8710w BIOS. Decompression works perfect. But If I try to compress and then decompress the BIOS parts, the results differ for some parts. I'm going to look into it, but I'm not very good in C language, but I'll try. If anybody is interested I can upload the parts which cause problems. My goal is to write a full BIOS compressor so I can make changes to the Video BIOS stored in the main BIOS.
N620c Bios Hi, could you send me a link for downloading the BIOS N620c version F16? I just change form N610c to N620c with the big problem that my wlan minipci ards don't works. Do even could add a small note how to flash the Bios. Thx for any help. Andreas
Please help for N620c Sorry for contacting you that way. I saw you have been able to offer a Bios/patch for N620c version F16 with no limits to the wlan cards. Could help me and tell me how to get. Please give me a note how to install it. Thx for any response. Kind regards, Andreas
N620c Thank you so much. I was unable to find it. It works perfect. You made my day. Kind regards, Andreas
Hello, How to make and flash a corrupted BIOS ? My question is serious: I've tried to flash an hex-edited BIOS with HPQFlash-patch but after reboot, a message saying the BIOS couldn't be updated appeared. Is there a way to force this flash ? I just hex edited it using WinHEX. Is there a way to fix the BIOS file so it would avoid the motherboard to refuse the new BIOS ? Thank you (and sorry for the silly question)
I have managed to create HP bios packer/unpacker. My tool should work for BIOSes which could be unpacked bu ADDC V3. I tested it on my HP 8710w BIOS. Currently I can replace modules like DSDT table, Video BIOS, Logo etc. I'll post the software after more testing. If somebody has a similar laptop and like to help me in testing, you can write here and I'll try to mod you BIOS. For myself I replaced boot logos and reduced voltage for the video card to make it run cooler.
