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!

SOURCE: Jabra bt250v Indicator light doesn't remain on...

i have just repaired my bt250 with this problem, i hadn't used it for around 2 years and when i put it on charge just got i flash of blue led. the fix was to "jumpstart it" the headset needs to se some sort of battery voltage to start the charging process, i stripped mine right down but that was just to fiddley. IF YOU DO THIS IT WILL BE ENTIRLEY AT YOUR OWN RISK AND I TAKE NO RESPONSIBILITY IF YOU TRASH YOUR OTHERWISE USELESS HEADSET. ok all you need to do is very carefully remove back cover (undo 1 screw and ease it apart). be very carefull as there are delicate wires inside. lift the inner part out slowly and you will see the battery.it has some orange tape around the end and there is a small circuit board attached to it with a small red wire and a small black wire. look at the battery and you will see under the orange tape there are to larger tags.these are the main battery terminals, peel back the orange tape just until the tags are slightly exposed. now you need to solder a wire to each of them and DON'T TOUCH THEM TOGETHER. on the battery it says which tag is + and which is - make sure you mark your wires or get red and black ones. now i used the lead from the charger. look at it . it has a hole in the center of the pin that is the + so put the + wire in there. if you are not sure use a volt meter. now touch the - wire to the outer metal of the connector that is the - point on the charger connector. hold this for around 2 mins but no more. as the out put of the connector is 6.2v and the battery is only 3.7v the battery will get warm. if the battery is getting too hot in under 2 mins then take of charge. when you have done that and taken off the connector i recommend to use a volt meter and just put it on the battery wires you soldered on to check battery voltage. as long as it reads you should be ok. de solder your wires from the tags and rebuild headset then try and charge it. this worked for me. i am no electronics expert i just like to mess with broken stuff so i know it seems a bit dodgy to connect like this but i had nothing to lose and it worked.

SOURCE: Unable to Detect the Jabra BT125 headset from any Bluetooth Device

If you hold down the button, it will turn the light blue, keep holding it till you can connect it. It will come up as Jabra BT125, hit connect. Then it will ask for a password. The password is 0000. Then it will connect :)

Not turning on. Blue light flashes then turns off


Fixing a Jabra with charge problems, demonstrated by the LED just flashing once when placed in the docking station/charger..
When my Jabra stopped charging after lying several months unused in a drawer, I looked around on the internet for a way to get it to charge again. All the methods to recover the battery that I read on the internet are probably dangerous for both the Jabra and the user. So here is a relatively safe and tested way to recover the battery.
Please note, Jabra does not supply any spare parts, there are none.....so fix it or throw it in the trash.
Its a good idea to charge them every 3-6 moths, to stop the problem ever happening to you.
I know this fix I will describe here works on both a Jabra 200 and a 250. I would expect it also to work on the 250V as well, though I have not had a problem with mine up to now.
Some other Jabra models, especially if they demonstrate the same problem as defined in Problem definition below with the indicator LED, may also be recoverable in the same way. Its worth trying.
Don't forget that all Jabras are designed as "throwaway", never to be repaired....that is probably true of most if not all Bluetooth headsets....Jabra models 200 and 250, I find to be the most comfortable ones to wear for long periods, whilst driving for example.
Problem definition.
First let me define the problem for you. If the battery in some Jabras (I cannot say all as I don't know if that is true), gets too deeply discharged by non useage, the charger will not recharge it. The indication that this is the problem is also easy to checkout, just stick the charger in a wall socket, connect the docking station and while watching the indicator LED on the Jabra, slip the Jabra into the docking station. If the LED just blinks once, you have the discharged battery problem. Probably fully recoverable if you are good with your fingers and have some knowledge of electrics or electronics.
Problem fix.
The only way to get the charger to restart, is to get the battery charged to at least 3 volts (its a 3.7 volt battery).
The best and safest method is to get hold of a lab power supply with adjustable voltage and current. I set mine to a fixed 3.7 volts and maximum of 300 milli amps. If you do not have access to such a power supply, look further down this article for a method using either 2 or 3 dry batteries, depending upon the type of battery and the terminal voltage available.
You will also need a voltmeter for either method.
Method
Remove the tiny crosshead screw that holds the Jabra togetherand gently and very slowly pull the headset apart, the wires are easily damaged, are very short, fragile and difficult to repair if you break them.
The Battery is obvious, but how to get to the contacts is not that easy. Carefully slip the battery out of its location and peel away the insulating tapearound the top end where the charger PCB is also mounted.
Identify the + and - of the battery either by either looking at the label (usually on the other side of the battery to the connections) or by measuring the voltage still on the battery and at the same time identifying which pole is the plus. Mark it. Usually a problem battery will have around 2.3 to 2.4 volts or less....
Apply the voltage/current that I detailed before from the lab supply (Plus to Plus, minus to minus) and watch the current meter on the Lab power Supply unit, it should go slowly down as the battery charges up. Stop charging for at least 10 seconds after 1 minute or less, constantly check battery temperature at the same time with a spare finger. If the battery starts warming up. STOP CHARGING. Let the battery cool down.
Always wear protective glasses in case the battery explodes.
Measure the battery voltage from time to time and once it is over say 3 volts, stop charging and attach to the docking station and see if the charger will now charge properly. If not, charge for another minute or so.
If it charges properly,carefully put the Jabra back together and continue charging.
First charge cycle after "Repair".
The first full charge after such a repair may take up to 12 hours before the LED finally goes out, even though a "normal" charge will generally only take 2 hours. This demonstrates clearly how run down the battery really is/was....
Another method to recharge the Jabra Battery for those without a Lab power Supply.
Connect 2 x 1.5 volt (NOT 1.2 volts cells as they will not charge correctly) together, or 3 x 1.2 volt cells together and use them to charge the Jabra internal battery with.
Monitor voltage and battery temperature constantly, till the battery voltage is above 3 volts, then try the normal charger as before. Do carefully iIdentify the positive and negative sides of the battery and apply the battery positive to the + side of the battery. The other polarity to the - side of the battery.
Take your time when charging and monitor both the battery voltage and its temperature carefully.
A series resistor may be used to keep the maximum current to a set maximum....say 10 or 20 Ohms.

Jabra BT350 Bluetooth Headset


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.
