Maybe phone has non original eeprom ?

Many of C55's have problem with DIALOG ic, but i am not sure that can be problem here. I have one C55 with "interminently dead" problem, it was originaly chinese phone, and converted to euro by someone who cheat my customers. After writing corect boot core all were ok.

press on the phone and check for some voltage on the earphone contact point, if some voltage happened to be leak to there, mean the dialog is broken and had to be replaced, i had some problem like this with C/A5X phone which has been using fake charger before
