HD2 data.img resize

This can be done with any data.img... even existing one one.
Boot phone in windows mobile. attach to linux box(linux computer or live cd) in disk mode(when u attach hd2 to computer it will ask mode,select disk mode).
go to terminal.
go to the /media
then go to the directory which represents your hd2 phone, then to android directory.
then enter following commands

e2fsck -f data.img
(if it asks to fix say y)

resize2fs -p data.img 512000
(this is for half gb, change it as per requirement)

e2fsck -f data.img

Then reboot the phone.
You may see green screen. if so, simply reboot again.
works like a charm.
no need to download huge file. can be done with a used data.img at any time and any number of times.
