Digital Signature PITA

[lewcamino]

I have search for about three hours now. On the forums and google. I can not find a way to make this work. Any help would be much appreciated.

I am simply trying to customize "phcanOverbmp.dll" so that it matches my phone pad skin. I use resource hacker to change the images and when I save the new DLL it looses the digital signature (expected).

I am using signtool.exe from the Visual Studio SDK and the certificates from the WM5 PPC SDK.

I tried wizard mode and I get "The Digital Signature wizard did not complete."

I also ran it via command line with the "/f SDKSamplePrivDeveloper.pfx" switch and I get "SignTool Error: ISignedCode::Sign returned error: 0x80070057"

I have tried "signcode_294" with the .bat file, that gives me "Error: Signing Failed. Result = 80070057, (-2147024809)"

I researched this issue and found that if it is XIP you cant sign it, but this .dll was taken from my device, so it should be PE.

I am really at a loss...

PLEASE help me solve this. There are soooo many things I have customized that I cant use cause of this issue.

Thanks, Lew

Ok, the problem is you are trying to edit a signed file. This is a big no no!
The thing is signature has a checksum. Once you edit a signed file it automatically becomes invalid so you can't run or resign it.

You need to find a way (sorry, can't help you there) to remove the signature before editing the file.

If you run the sdk cab before replacing "phcanOverbmp.dll" it will work. It did for the batteryfix project that i helped jimm98y with

download one of his earlier zips that has the file you need in it. Can be combined all in one cab. edit i attached it

see here http://forum.xda-developers.com/showthread.php?t=267321&highlight=battery+fix

Thanks,

I installed that cab to my TyTN and the dll still is a no go. Any other ideas or ways to digitally sign it? I am really desperate, I have been trying for soooo long to get these to work.

Thanks, Lew

Thats strange can you send me the file to my email eschlem@tiscali.co.uk and i will try to get it to work. I will include it in a cab i made before and see if that does the trick.

Any chance you're using Windows 2000 SP4, If so you might want to check out this link.

Probably not the issue but, I figured I'd mention it just in case.

[lewcamino]

Sorry, but I am running Windows 95 version C. So I don't think that is the issue.

I just got a chance to check the forums, I will e-mail you the dll.

Thanks again, Lew

P.S. I am running XP sp2 :p

I've got a similar problem. I tryed to edit some dll's from HTC Touch Phone Pad International, but since they are digitaly signed, i can't change the contents without invalidating the digital signature. The goal would be to make the phone pad look more like the dialpad. I've created all the pictures I need, and I know which dll's to change. I'm using PE Explorer to edit the resources from the dll's, but first I need a way to remove the digital signature, and after changes are made, re-sign it.

Advices anyone?

Well I got it to work. With some help I was able to rebuild the signature in the changed dll's.

How did you achieve this? I am having the same problem and i guess i need to somehow remove the signature too.

[aje_fr]

Yes, it'll be great to have some information about achieving this!
Thanks in advance
