problems with 7100t

[onefastm]

hi everybody. I recently purchased an unlocked blackberry 7100t. I put the sim into it and put the charger in the wall but all it seems to do is have a hour glass appear every 7 seconds. What is wrong? is this how it normally charges?

anybody please?

Do u think it needs a new battery?

try re-installing the system software/os.
