Good day robbiekr,
What is ment is the following:
First do a hard reset. When the device reboots, just before
the customisation starts, do a soft reset.
The device will now not
customize (i.e. add all the T-Mobile stuff
Any item you do like from the Extended rom can be installed later. (
using Total Commander to copy the ExtRom and then piece by piece executing the ExtRom Cabs)
In the ExtRom are for instance the Smart Dialling function, the MMS application etc.....
Hope this is sufficient,
PS Perjan: getting rid of the dialer skin: "HKEY_LOCAL_MACHINE\Security\Phone\Skin" set "Enabled" to 0 and softreset
