Here's a solution for Nokia X3-01 with bluetooth related problem such as unable to turn the bluetooth ON, bluetooth operation failed.
This solution provides some simple tips on how to fix the device if this problem occurred. Refer to the solution below and locate the highlighted components on the X3-01 PCB board. then do some test and check-up procedures.
You may start checking the Bluetooth module chip supply voltages in two capacitors. These voltages range 2.6V and the other one is 3.8 volts.
If the voltage readings is okay, check the UART resistors then replace if found damaged or faulty.
The next step is to reheat, rework or replace the Bluetoot IC if the above steps is already been done and if the problem still exists.
If seems the above procedures does not solved the problem the next option is to replace the Bluetooth crystal oscillator.
