Hi guys, I bought my first Android phone, a U8150. It can with 2degree's crippled firmware, no RDS support constant slowness among other things.

I took off the 2degrees firmware, put on some custom firmware. I don't really like it, so I would like to go to another provider firmware if possible.

 

I really want to experiment with the T-mobile comet firmware, since that's from the USA and it would have to have all the functions.

Question is how would I install it, the file I downloaded comes with a single large file. (UPDATE.APP) and I have to find a way to install it. It's not like the custom files, when it's in a special .zip file. This is just a single file, and to my Knowledge there's no way of installing such files.

Can someone please help me?

Thanks
