Hi. I have an early razr with the small charger socket with 5 tiny pins. The wires have pulled off the mains end. Although they have left enough to reconnect i need to make sure i get the polarity correct. I know it uses the 2 outside pins but do you know which one is pos and which is neg. Thanks Martin

Binatone bb200


I've had exactly the same problem. The connector that plugs into the docking cradle (or phone if you don't use the cradle) is faulty. Mine had a short circuit. Try gently moving the cable closest to the connector. Alternatively, turn off the charger at the mains socket, leave for 10 minutes or so then switch back on. If that doesn't prove it and you're lucky enough to have another charger, try that to see if the original is at fault.

Be warned that even though it's a 5.2V charger and a common USB type should work, getting hold of the identical USB connecting cable I found impossible. I had no luck sourcing a replacement Binatone charger either.

In the end I removed the sticker from the base of the cradle revealing the screw then undid it to dismantle the cradle. The cradle is very simple so don't worry. I cut the USB plug off the charger, bared & tinned the wires then soldered them directly to the docking contacts (wire with feint white broken line is +5V and should go to CH- solder pad, the plain black 0V wire goes to CH+). You'll have to cut a small notch in the lower edge of the cradle to pass the wires through before reassembly.

The soldering's very easy but don't overheat the pads otherwise the contacts will fall off which might be tricky to reposition. I'm quite handy with a soldering iron but if you're not, it's only a 5 minute job for anyone that's competent.

I have an early Razr (5 years old). Is it quad


YES!!

I think all Razr handsets are GSM and it only needs to be tri band to work across Europe.

Hope this helps? :)

RAZR V3m shutting down randomly


You may try putting a small, thin piece of b under the battery directly on top of the small metal tab, put the battery back in, see if this pressure is enough to keep your phone on.
Sometimes the cell phone deals people are getting on Ebay actually result in more frustration and disappointment.

You may consider cutting your loss and purchasing a new phone, or getting a FREE phone from one of the major carriers.

I highly recommend the following company for getting your next phone, the customer service is excellent and the selection is great. I also recommend folks in getting insurance on their new phones as well. I hope this helps you, best wishes :)

Power/data socket rattles Phone will not charge


The charge ports do break loose. If you know somebody who knows how to solder very well they can reattach it. Some times the copper PC board traces pull up with the legs of the mini USB port and need to be connected with some fine wire. This should be no problem for a decent electronice tech. Your other option is to find another phone in which to charge the battery. The battery is a BR50 and I charge them off the phone with two tiny alligator clips attached to the leads of an old charger. These are about 800mAh so a dead battery will take an hour or so to charge. The voltage of a fully charged 3.7 Volt Lithium Ion battery under no load should be about 4.05 volts. You can check with a volt meter. Removing the main board to access the charge port will require a T5 (Torx bit) screwdriver. Lift off the battery cover pry the plastic piece off the bottom and remove the screws. Then carefully pry the two flex cable connectors off from under the board. Lift it out and resolder the charge port. Repost if you are having any troubles.

My razr v3m always thinks its charging even when i take the charger out it still says charging. and the phone wont stay off it turns right back on and says unauthorized charger


Sounds like the connector for the charger/data cable has become damages, there are tiny pin contacts inside that can get bent or the female port on the phone can become wallowed out. If you have insurance on your phone you can take it back and have it replaced. You might also try some compressed air blown into the connector gently to see if there is something stuck inside.

Check also the charger cable end if you look carefully inside you can see the pins, make sure they aren' bent or pushed in, might have bad charger connector.

Hope this helps

It will not charge


1. The charger may be damaged To check if the charger is damaged, use another functioning charger. The charger cable has a tiny wire that easily breaks when used without proper care. If the phone still does not charge with a functioning charger, try next step. 2. The battery may be damaged Change the battery and try charging again. If the phone still does not charge with a functioning battery, try next step. 3. The battery terminals may not connect properly with the battery connectors Check the battery connector to see if the battery and the connector connects well. The phone will indicate charging only when there?s enough power supply from the battery. click here Solution Procedure: If problem is confirmed, adjust the battery connector using tweezers to reach the battery terminal and establish connection. Or try next step. 4. The charging pin may be damaged or does not connect well with the board's interface Check the charging pins to see if they are well connected to the mother board. Sometimes the charging pins wear out or loosens from its connection with the mother board. click here Solution Procedure: Check if the pin is bent. Straighten the pin using tweezers. Make sure the board interface is also clean otherwise, you will need to clean it by rubbing its surface using an eraser or brushing it with a board solution. Or replace with a new charging pin. Make sure the charging pin touches with the board interface to establish connection. 5. The CCONT IC for DCT3 or UEM for DCT4 or the "K" resister for non-Nokia models may be damaged If the phone still does not charge after adjustments are made, the problem is CCONT IC for DCT3 or UEM for DCT4 or ?K? resister for non-Nokia models. click here
