OEMMisc cleanup/breakdown

So, anyone who has attempted to cook a ROM for their GW82x's should have noticed by now that most of the OEM junk is located in OEM\OEMMisc.

Unlike HTC, who attempt to separate a lot of their software into separate folders/packages (which benefits them and us), LG dumped everything into a single folder.  

You can choose to exclude OEMMisc completely, but you will lose some functionality.

Personally, I would like to determine which files are necessary to maintain all functionality, while removing all unnecessary OEM software.  

I started this thread so that we can collaborate all of our work instead of trying to figure it all out for ourselves.  I've spent a lot of time trying different things and flashing my phone (over 100 flashes so far) and I still have a way to go.

So lets get to work!!      

Attached to this post are two documents that list the files that are unique to the GW820 and to the GW825...

I find the GW825 OEMMisc to be a much cleaner base to work with as Telus added a lot less crap that AT&T.

For the most part you can delete the files that are exclusive to whichever OEMMisc you are using.  These files were added by either Telus or AT&T and not needed (unless you want it I suppose).

Exceptions:
- If you are using the GW825 as your base, you will notice a lot of the unique files are language related.  Telus added French support to the GW825 (IQ), so assuming you don't need French support a lot of that can be removed.  This also means that some of the exclusive files to the GW825 are actually needed, but are listed only because they are language specific.  If a file is listed as exclusive to the GW825, but has 0409 as part of the filename, you will want to compare that to the GW820 list to see if you actually need it.

I used WinDiff to do the comparison (great program) and the same comparison can be made to the registry file (xxx.rgu) to see the differences.  Knowing the differences allows you to determine which sections can be removed or changed.

I was taking a look at your list it is pretty comprehensive you took out a LOT of stuff including start menu icons it seems gutting it was your objective and kind sir you have gutted it mighty well.

some more to add though

(1mb so far saved and wasted i havent used those files at all)
if you want superior space saving
StartUpAni_DMDO_000.dll(20mb) although i was finally able to modify it and make it my own so i keep it
ShutDownAni_DMDO_000.dll(14mb)
dont need it imo because it takes our expo longer to shutdown
total so far extra =35mb

The screen rotation issue has to do with what i think is the rotatemanager.dll located in the oemmisc folder i could have sworn it controls the accelerometer in our phone.

Shutdown:
- This one was tricky, but seems so obvious after the fact.

If you hold the power button down for several seconds, the phone launches Shutdown.exe (I'm sure everyone has already noticed this).  Shutdown.exe is located in OEMMisc and will obviously be missing if you don't include this folder.  If you want to add it back in you need 3 files.

ShutDown.exe
ShutDownAni_DMDO_000.dll
LGString.dll (LGString.dll + LGString.dll.0409.mui if you are using an IQ base)
*LGString.dll is used by several LG apps including many of the System Control Panel Apps (Clear Storage & Wireless LAN for example)

If you just include ShutDown.exe and not ShutDownAni_DMDO_000.dll, the phone radio will turn off and the touch screen will be disabled, but your phone will not turn off.  Without LGString.dll you will be missing the dialog text.

You could also launch any problem you like by calling it ShutDown.exe and placing it in \Windows.

It may also be worth changing the resources inside ShutDownAni_DMDO_000.dll (perhaps a still image) so that it doesn't take up 16MB.

*Note: Startup animation (StartUpAni.dll) is not required.  ShutDown.exe controls the shutdown animation.

zalooa, if you are still using WM 6.5, that may be the difference. 

I just built a 6.5.3 ROM without ShutDownAni_DMDO_000.dll.  Once it was up and running I tried to execute ShutDown.exe.  The warning came up and I hit OK.  The phone radio turns off and the screen no longer responds to touch, but it doesn't shut down.  The keyboard still worked, so I used it to open the start menu and reboot the phone.

Once it was back up I copied ShutDownAni_DMDO_000.dll to \Windows and tried it again.  This time it worked. 

If it works for you, then I guess we can assume it is not needed for WM 6.5, but is needed for 6.5.3 and most likely 6.5.5.

wawa that sucks 6.5.3 or 6.5.5 needs the shutdown dll what a waste of space and time for it to shutdown i am sure there is a way to remove it in registry because i found the entries there so it wont be a requirement 16mb is big cheese on our tiny device. of course i stay at 6.5 for now till the other 2 or more get a little more stable they are hella nice lookin though. and finger friendlier than 6.5's TINY OK button located under my HUGE thumb SHEESH ms really!

Warraven i am taking a look into that link for the power
it would seem it is either attached to the keyboard.dll file like all the rest of the keys or it is a registry key like the camera button multitask voice command. Very interesting if we find something for it in the oemmisc folder.

Organize the OEMMISC

I started to separate the files based on dependencies or associated files ie. DLL or  base files closer to/ or at the root (OEMMISC) with packages grouped on their respective branches..

eg. Java dir would contain All files Java needs to execute (Unless another program also requires that file in which case the file in question would be moved closer to the root). Java/iskoot  contains files only iskoot needs and branch ends.

      -text file attached-

if any one wants to continue it- I left any files I was unsure of in the root.
feel free to move and reorganize if I screwed up   and queries are welcome.
*** Don't delete any files***

Once it is complete I'll upload the folder.
