Nokia 105 Rm 908 Usb Pinout ^hot^ File
A hot air station is recommended for removing the USB port, while a fine-tip soldering iron is needed for soldering the jumper wires.
The Nokia 105 RM-908 utilizes a standard 5-pin micro-USB interface primarily configured for charging, firmware flashing, and servicing via specialized box interfaces (like Miracle Box, Infinity-Box BEST, or UFS).
| Pin | Signal | Function | Wire Color (typical) | |-----|--------|----------|----------------------| | 1 | VBUS | +5V Charging Power | Red | | 2 | D- | Data Minus (unused in this model) | White | | 3 | D+ | Data Plus (unused in this model) | Green | | 4 | ID | For OTG (not supported) / sometimes used for charging mode detection | None (or tied to GND via resistor) | | 5 | GND | Ground | Black |
Do not reverse polarity. Connecting +5V to GND will destroy the power management IC instantly.

Without this connection, the Nokia 105 RM-908 will not charge from many power sources.
The Nokia 105 (Model RM-908) is a classic, durable feature phone. Because it lacks a native micro-USB port for data transfer, flashing the firmware or recovering data requires direct access to the motherboard. Technicians must connect directly to the hardware test points.
Best Dongle or Phoenix Service Software.
Can be soldered to any large copper shielding plate or the negative battery terminal. A hot air station is recommended for removing
Unlike modern smartphones that use standard USB controllers, the Nokia 105 RM-908 relies on a MediaTek (MTK) processor. Service communication happens through specific Test Points (TP) on the motherboard.
Unlike many Nokia feature phones of the 2000s that used Pop-Port or 2mm DC jacks, the RM-908 uses a standard 5-pin micro-USB socket. However, Nokia deliberately disabled mass storage mode. This means plugging a standard USB cable into a PC will only provide power – no device enumeration.

Turn off power, switch the multimeter to Diode Mode, place the Red probe on GND, and the Black probe on Pin 1 . You should see a reading between 400mV and 700mV . A reading of 0.00 indicates a direct short circuit in the charging IC or protection zener diode. A reading of 1 or OL indicates an open loop/broken trace. Connecting +5V to GND will destroy the power
Check the 10kΩ resistor between pin 4 (ID) and ground. It may be damaged. Also verify the charging IC (usually a small 6-pin IC near the USB port) is getting VBUS.
When connecting the phone to a flashing box (like Infinity-Box or Advance Turbo Flasher) using a modified USB cable, follow this pin configuration: Battery Positive (+) Pin 2 (TX): Data Transmit Pin 3 (RX): Data Receive Pin 4 (MBUS): Combined data line Pin 5 (GND): Ground / Battery Negative (-) Draft Post: Nokia 105 (RM-908) Flashing & USB Pinout
Connect: Pin 1 (VBUS) → Red wire → +5V from USB host Pin 5 (GND) → Black wire → USB GND
Used for USB communication (limited support on RM-908).
