New unbranded ROM on Vodafone branded Touch Dual

[pinobird]

Hello,

I''m kinda new into ROM flashing and am curious to know if the HTC Touch Dual i got from my father in law is flashable with a new unbranded dutch ROM.

This model is now Vodafone branded and i want to use it with an other provider. I also don't like the presettings of Vodafone and the startup Vodafone image.

I found several links for unlocking and reflash a new ROM but don't know were to start. So I have the following questions:

How can I make a back-up of the current ROM?
How can I flash a new ROM? (I've downloaded the Nike_Original_NLD_ROM_v1.31.404.09_Patched_Touch_D LL.exe)
If 2 isn't possible how can I unloch the Touch Dual?


I'm very greatfull for any advise!

Thanks,

Pinobird

After that you can flash your Rom's.

As for back-up, I don't know, but it has been posted, more than once.

Also learn to read sticky threads and search.
