I have a Sensation XL that I managed to root and install a new OS on, but then tried to undo this to restore it back to it's original factory settings and it never worked, and now the phone is constantly stuck on this boot screen (attahced) does nothing else, and no matter what options I choose from the menu, it always comes back to this.
It has wiped everything off the phone, and I can't do anything with it.
Is there any way to get it restored back to factory settings, anywhere I can download and install these?
This is the first time I've ever attempted to root a phone, so not 100% sure the exact process to follow.
If I am able to restore firmware, please give advice in small steps please
If it makes any difference, it was originally unlocked, and using a 3UK sim.
Thanks very much in advance!!
