2628 problems - GSM-Forum

Sometimes i cannot turn it on at all.
Simetimes, only green LED lights or blinking when i press power on. Or it can be turned on normaly, works for few seconds and then freezes. I must remove battery to turn it on again!

I cannot flash it with DIV or any other sw.
When i try to read codes, i allways get some nonsense characters.

Please help me with this one!
