Hello,

I advice you try get a similar charger to charge your phone, if the similar charges your phone, it means your charger is bad and will need to get another charger or the phone.

But if it did not charge and you still get the same message, it means the charging port on your phone is the problem, the charging port on your phone is bad and can not read the charger, so you will need to replace or change the charging port on your phone. Doing thi will solve the problem on your phone.

Take care.

IF THIS CHARGER IS AN AFTERMARKET IT MAY NOT WORK WITH THE PHONE

change your battery and charger. tnx

There may be a problem with your charger output. Do you have another charger you could try?

A temporary workaround is to reboot the phone with the charger still attached. It should now say "Authorized" and start charging.

you can try to clean the charger port (but first make sure its not bent, or broken - the pins are really tiny and hard to see, so make sure)
But try cleaning the charge port on the phone and the charger with denatured (rubbing) alcohol, and a toothbrush -

Just make sure not to plug it in when you do this!

and clean both the charger and phone, make sure neither are bent
lastly, try a new charger!

I'm not sure what the problem is with your phone, but this happened to me with another Motorola phone and it turned out to be a battery problem. You can try another charger, which might work for some time before you get the same result, but I believe you will need to replace the battery. You can try calling Motorola and checking to see if they will give you a discount on another battery. I've had several Motorola phones give me this same message and most of the time it was only infrequently and resetting the phone and reinserting the charger worked, but if it persists, try the battery.

unfortunately the phone needs to be reflash but this will delete all information on the phone.
So take the phone to a mobile service center and have that done.

I'm not very sure about how the problem can be fixed, but the best thing to try is probably to make sure the charger is clean, and if it still doesn't work, try it on a different RAZR charger.
