So this phone is recently bought and is giving problems.For example sometimes it shuts down a program like bluetooth or Android market and gives this:We're sorry,use *#9900# to take log.

Also ,it constantly shuts down and gives this when happens:

POWER RESET or UNKNOWN UPLOAD MODE with the android icon next to it.

When i go to the phone caracteristics(i have the language in romanian so im trying to translate my best),it's basically this :
Model:GT-I9003
Firmware version: 2.2.1
Baseband version: I9003XXJL9
Kernel version:
2.6.32.9
root@sep-60#1
Build number:
FROYO.XXJL9

What could be the issue?

EDIT:It seems the basic programs you have and cannot be normally removed like as i said previously bluetooth,Android market,TWLauncher(???) etc. i get constant message saying we're sorry blablabla.

And the commands are usually kinda slow
