k850i help needed please..!!

hello guys,im not pretty sure if this is the right place to ask something like this but i really need help..first off,i used the search function so that wouldnt be a helpfull answer for me,because i didnt find an answer that would solve my problem :) and now to the facts:
- a friend of mine gave me his K850i because he had no use for it anymore,btw the display of the phone was broken and the battery was fault,so the phone wasacctually in no function..i decided to take a look at the phone inside (alredy owned a k850i and dissasembled it about 100 times) but i couldnt find anything strange in it..i bought a new battery for the phone,an lithium polymer battery that managed to turn on the phone but not for long - the phone turned off due to the battery was empty..well i turned a charger into the phone and i got the red led lightning for a few seconds,after that the phone vibrated for a second and it turned on..after a few tries i noticed that it means that the phone isnt actually charging after the keypad lightens up,it just turns off again..i managed to take out a friends display from his k850 and try it again but still the same..i even tried different battery,keypad etc. but nothing helped..i noticed when i connect the phone to a2 uploader that all the content from phone memory is gone,that means all the default folders like camera album,music,themes etc.
i think now that this could be somthing around the EROM but im not sure if there is an method to repair that on DB3150 phones like k850i,but im still not sure what the hell erom has to do with the charging problem?! o.O the battery is 100% OK and its original SE battery..
many thanks for any help =)

I have this problem try to charge phone with some other charger

thanks for your reply,ill give it a try when im back home..im out of town at the time,but thanks anyway ;)

If hardware is ok in that phone then gdfs is damaged.You have to write backup from another k850 and unlock the phone by reset after that.You will need Omnius license and you can download gdfs from sticky thread in Omnius forum.

well,like i said,the display is broken,but it did charge before with that display,but now nothing..and the red led isnt really blinking,it just lights up for a few seconds,then the keys light up and it turns off,like it isnt charging..and every time the same when i try to charge..ill try some solutions before taking it to a service,but thanks for the help guys ;)
