IMHO it is a problem, at least I'd hate it when Start icon wouldn't appear on my Kaiser.

@lambrechts

I see from the portion of the screen of your phone that you have some kind of Today screen customization (those big buttons on top).

While I'm not 100% sure, I could bet that this is what is causing your Start icon disappeariance. Perhaps it require some additional components, or depends on something etc - I don't know, I'm just guessing, obviously I can't help you without having physically same customizations on my Kaiser too.

/edit: Is it some kind of ported app from other phone? Perhaps the Start icon (inside the dll it came with) wasn't resized/scaled down to the Kaiser's screen resolution? That is common reason with ported apps' problems actually - I did very same mistake once when I was porting CABs too, and some icons didn't appear. If you look at the HTC Task Manager 2.1.34563 that come with eXt.Pack you'll notice its icon is exactly the example of not properly ported application, the icon left in the dll is for much larger display resolution than Kaiser's thus it appears on Kaiser partially only as 2 lines, missing 3/4 of the rest of the original icon; lucky for us those lines start from the top of the large icon and we can see them even though the icon is displayed only partially on Kaiser's resolution, but if (for example) if they were in the middle of its large icon we wouldn't have see them all, same as we don't see the arrow pointing down at the bottom of this large (that is actually there). Hence it would look like icon is missing while in reality icon is there but we see it only partially (the empty space of the left top corner portion of the large icon).

And sometimes even if you uninstall the app, it may not remove its files or dll(s) and restore back original files, hence its "effect" may stay there on your phone while the app itself is long gone and forgotten.

@dancj

Certainly it is side-effect of something.

Since both of you have same problem (or so it appears), perhaps if you two compare what apps you have installed you'll find which one did or does it?

Thats excellent.

Copy/paste filenames is the best way to avoid making any spelling mistakes etc.

Since you are sure all the directores and filenames are correct, the only possibility left for your apps not installing is that probably one of your apps needs some user input when it is installed.

There are no mysteries to UC and SDconfig.txt ;)

It is very simple process: either SDConfig.txt is written correctly and UC works,

or it isn't - and UC won't work at all or will work only partially as in your case.

There are only few possibilities in general for incorrect SDConfig:

wrong filenames

wrong directories

missing files

application requiring user input during installation (this usually hangs the installer).

Since we eliminated first three and you're sure filenames/directories/file existence is all correct...

/edit: also the text file must be in ASCII (just make sure your Notepad or whatever text editor you use to edit SDConfig.txt isn't using Unicode or any other non-english defaults if you use other than English language).

My suggestion:

Hard reset your phone using your SDConfig but first disable all your apps you've added there (with ":")

Then start installing them manually in the same order you had them in your SDConfig.

I'm sure you'll find one of them will require either serial number or it would like to display some kind of warning or any other message, before it proceeds with installation (or it will just want to do something else outside of the usual installation process, there are many possibilities). That will be the app you should use unlock/lock commands for.

Once you'll find it out which application was causing it, simply move its line to the SDconfig section where it says "APPS REQUIRING USER INPUT".

/edit: or simply add following lines before and after that app's line:

[B]LOCK:Disabled[/B]
CAB: \Storage Card\...\YourApp.CAB
[B]LOCK:Enabled[/B]

HTH :)
