Easy, just download Total commander from http://www.ghisler.com/

Open it up and at the top type \Extended_Rom

This will show the contents of your extended rom, you will see loads of things but the ones you want are the cabs relating to your provider. Or all providers actually, Delete allt the cabs that dont start with Default_ these are what brand your device when you hard reset.

Now just hard reset, it will isntall all the normal stuff but will leave you with a brand free jamin.

You need to download and install Windows CE FS plug-in. You will then see a mobile device entry in the file window. I recommend dragging it to the toolbar so you will always have a button for convenient access (total commander can open files directly form the device).

Also I don't remember it now, but if you search this forum there is a registry tweak that will unhide your extended ROM so you can use it for extra storage space (and manipulate files in it using regular explorer both on device and PC). You can use the free PHM Registry editor to apply the tweak.

Just follow the instructions to install total commander onto your PPC. Make sure you click the link to the mobile version and not the desktop version.

thanks dannyoneill, got it working..

jsut a few other questions if u dont mind

im in the \Extended_Rom folder with the default stuff but the telstra stuff i want to get rid of has Default_Telstra_australia_SA_UN_V2.20.CAB and also Default_Australia_Telstra.CAB as the file names, will these be ok to delete still ?

thanks

[dannyoneill]

Yes, you can delete them.

If you really want everything here is safe to delete. What it usually contains are patches like driver updates, applications like the backgammon, antivirus and Skype.

Below is taken from another post, its a little out of date but still good to see whats what. For me. I removed all the operators apart from my own (as it doesnt brand) plus got rid of backgammon, antivirus (totally useless on a PPC) and skype as the latest version is better (especially if you apply the registry fix to get it working)

Autorun.exe
Default_Backgammon_PPC_IMAM001.CAB >>> Backgammon
Default_CAAVPPC_IMEI_Wiz_range.CAB >>> THE DREADED ANTI VIRUS STUFF
Default_CAB-shortcut-CDL-08Sep05.CAB >>> Clearview PDF
Default_cdl_wwe_version.cab >>> Some Imate stuff (Harmless)
Default_ie_view.sa.cab >>> Some Imate stuff (Harmless)
Default_Imate_PPC_SA_V5.5.03.cab >>> Some Imate stuff (Harmless)
Default_SkypeForPocketPCnonxScale.CAB >>> SKYPE FOR NONE XSCALE !!!
Default_SmartDialing_enable_0915_signed.CAB >>> The pretty Dialer and smart-dialer stuff
Install_Tsk.exe >>> This Installs all the “Default_” Files
Setup.exe >>> This allows for Selection of the “Operator Settings”

These are the “Settings” which is not needed at least in the GULF STATES

KPN_Nederland.CAB
MTN_SouthAfrica.CAB
O2_UK_Contract.CAB
O2_UK_PAYG.CAB
Optus_Settings.CAB
Orange_Nederland.CAB
Orange_UK_Contract.CAB
Orange_UK_PAYG.CAB

T-Mobile_Nederland.CAB
T-Mobile_UK.CAB
Telfort_Nederland.CAB
TelstraClear_NZ.CAB
Telstra_Australia.CAB
Virgin_UK.CAB
Vodacom_SA_WAP1.2.CAB
Vodacom_SA_WAP2.0.CAB
Vodafone_AU.CAB
Vodafone_Nederland.CAB
Vodafone_NZ.CAB
Vodafone_UK_Contract.CAB
Vodafone_UK_PAYT.CA

I made a copy of all of the above to an SD card BEFORE DOING ANYTHING else (NoBackUp…learned his lesson……Harry Potter !!!)

So I Reduced my ER to Just

Autorun.exe
Default_Backgammon_PPC_IMAM001.CAB
Default_CAB-shortcut-CDL-08Sep05.CAB
Default_cdl_wwe_version.cab
Default_ie_view.sa.cab
Default_Imate_PPC_SA_V5.5.03.cab
Default_SkypeForPocketPCnonxScale.CAB
Install_Tsk.exe
Setup.exe


How just simply Delete !!!

Don’t forget to hard reset let the imate setup run (will not only install the stuff you did not delete) and try out your new toy.

Poll for sticking this 3d!

THANKS !!!

P.S.: may I install basic stuff to the ExtROM while it's hidden ?
Or, if I need to unhide it, install, then re-hide, will such software still playable ?
I mean for example:
- Total commander itself
- Resco explorer
- Storage tools
- Sprite Backup
- and so on...

Is it a strange idea ?

Thanks again for this illuminating thread.

You can unlock and install things no problem, not done it myself, done know if they will still be usable after its re-hidden i would think not.

The extended rom is reserved so empty or not its not going to give you more ram or rom storage at all. The best thing to do is unlock it and use it for storage. The annoying thing is if you hard reset you then have to re-unlock it.

dannyoneill thanks heaps,

BTW, on the i-mate website's (www.clubimate.com) JAMin support pages, you will find specific operator settings for Optus in a downloadable CAB file, which will setup the wireless settings for your device.
