For a professional repair, follow these steps:

Disassemble the device carefully using a #6 Torx screwdriver. Clean the charging connector pads and surrounding areas on the motherboard with isopropyl alcohol to remove corrosion or oxidation that may block current flow.

The of the Nokia RM-495 revolve around three critical sections: the micro-USB port, the charging IC (EM3078), and the battery connector. In most dead-charge cases, the issue is either a broken USB port or a faulty current-sense resistor. Direct jumper solutions (Way 1 and Way 2) provide a functional, though unprotected, alternative for emergency use.

If the charging IC is faulty, replace it with a new one.
