Nokia X3-01 Bluetooth Repair Solution
KM Sariful
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.

If you change the spread. Change the speaker volume, and then try
to check the following offline.
- Remove Varister R2518 R2519 and try the test again.
- Check if not recovered R 0 Ohm resistance to R2507 R2508.
If the broken or stretched. Find and change or remove it, then direct
Head to the end of the two.
