You can get the unlock code here http://www.theunlockarena.com/unlock-your-phone/rs13wp2/ and also get the unlock instruction in the same site...

Turn your headset off. Then, press and hold the answer/end button until the indicator light is solid lit in blue. It is in paring mode. Now, make your phone's bluetooth application search for new devices. After a while, the BT-350 should appear on-screen. Select it and command the application to proceed. If a pairing code (or PIN, or passkey) is requested, enter '0000' (four zeros). If the pairing proces is successful, the headset should enter stand-by mode. The pairing process is timed.If you fail to complete it, you'll have to start it over, from the phone turned off phase. Once paired, whenever both your headset and your phone's bluetooth radios are turned on, they should connect to each other automatically. Otherwise

This is what I did:
1. open the headset by following these steps:
http://www.instructables.com/id/Jabra-BT-350-Disassembly-and-Repair/
2. measure the voltage of the battery. If it is too low, the internal charger circuit may not like it. Mine was 2.6v.
3. Charge the battery "manually" by connecting to 3 serially connected rechargeable batteries (final voltage should be around 3.7v). Three NiMH AA batteries are fine.
4. Reassemble and hope your headset is back to business.

Hey everyone! I had the same problem, and I actually got it to work again! I hope these directions will help you get yours to work (from the manual):
1. Put the headset in pairing mode
• Make sure the headset is off.
• Press and hold the answer/end button until a solid blue light comes on. <== THIS IS VERY IMPORTANT! HOLD THE BUTTON UNTIL YOU SEE A SOLID NON-BLINKING LIGHT! (This is where I was going wrong with the directions.)
2. Set your Bluetooth phone to ‘discover’ the Jabra BT350
Follow your phone’s instruction guide. This usually involves going to a ‘setup,’ ‘connect’ or ‘Bluetooth’ menu on your phone and selecting the option to ‘discover’ or ‘add’ a Bluetooth device.
3. Your phone will find the Jabra BT350
Your phone then asks if you want to pair with it. Accept by pressing ‘Yes’ or ‘OK’ on the phone and confirm with the passkey or PIN = 0000 (4 zeros).

Good luck!

BT350 passcode is 4 zeros... > 0000
