Refer to the "Charging Jumper Ways" section above to trace the circuits. Conclusion

The Nokia 105 (RM-908), released around 2013-2015, is a legendary feature phone known for its durability and massive battery life. However, even the toughest phones suffer from broken charging ports or failed data connections due to wear and tear.

When looking at the PCB (motherboard) with the USB port facing down, the pads are usually arranged in the following manner (from left to right): VBUS (Red): The extreme left pad. D- (White): Data Minus. D+ (Green): Data Plus. Not Connected. GND (Black): Nokia 105 Rm 908 Usb Pinout

For simple charging repair, you only need to connect VBUS and GND. For flashing, you need all four lines. 3. Nokia 105 Charging Jumper Ways (Broken Port)

Solder a wire from the VBUS pin of the new charging port to the VBUS test point on the PCB. Solder Ground:

Soldering on these pads requires a steady hand and a fine-tip soldering iron. Incorrect soldering can permanently damage the phone. 5. Troubleshooting Common USB Problems No Charging Showing:

The RM-908 model typically utilizes a interface for standard charging and a specialized FBUS (Flash Bus) interface for deeper technical operations such as firmware updates or security code resets. 1. Micro-USB Pinout (Standard Charging/Data)

Check the fuse component near the charging port. It is often burnt out. Replace it or bridge it with a thin jumper wire. "Charging Not Supported": Cut When looking at the PCB (motherboard) with

The RM-908 does not come with a standard Micro-USB or Mini-USB port exposed to the user. Instead, it utilizes proprietary spring contacts inside the battery compartment or near the battery connector for factory programming. To interface with a computer for software repairs, you must bridge these contacts to a standard USB cable.

Using a higher current charger (e.g., 2A) is fine – the phone will only draw what it needs.
