help-8210

[Imob]

Hi there everyone

I have 3 8210 phones by me.The 1st phone dsiplays the message "Contact Service".The 2nd phone is completely dead,it just wont go on at all.I suppose it is a dead set.The 3rd phone displays the message "Insert sim card".I suppose all these are software problems.I purchased a universal box from a company called Jexun Tech.The instruction booklet is in Chinese so i dont understand it.What i do know is that for Contact Service i need to connect via the LPT port.The software which comes with it (the box) is the Nokia DCT3 Flasher by Rolis,Nokia tool by Rolis 1.7,Nokia unlocker v6.0,eeprom repair.This is the 1st time im using the box so i need someone to explain me the Exact way to sort out these 3 problems.

Thanks so much to everyone who will help me
