Resolve “Battery cannot be charged. You must use a Sony Ericsson battery.” on Sony Ericsson C903

Here is a quick post on how to resolve the “Battery cannot be charged. You must use a Sony Ericsson battery.” message when connecting a Sony Ericsson to the charger.

First you will need the Sony Ericsson DCU-60 data cable, I purchased this from eBay for $2 including worldwide shipping.

Secondly, download the Sony Ericsson Update Service software.

Once the cable arrives, connect it to your phone and run the Update Service software, most likely you will receive a phone is already updated message, ignore that and continue to update the software, after a large download and install follow the prompts to update the software.

That should be all that is needed to resolve Battery cannot be charged issue.

Battery cannot be charged. You must use a Sony Ericsson battery.

Unlock a Sony Ericsson mobile locked to the 3 (Hutchison) network

I recently acquired a Sonya Ericson C903 handset, which was locked to the now defunct Three network (formerly Hutchison Australia) which was recently acquired by Vodafone.

Vodafone has a free service that provides the relevant unlocking code when given the IMEI number of the phone;

They will also provide the unlocking procedure as per the following document;

Sony Ericsson Unlocking Procedures

Now the problem is you need a working 3 network SIM, where do you get this from?

For free, you can go into any Vodafone store and ask for a ‘blank 3 SIM’, which you can use to allow you to follow the above Unlocking Procedure in store.

It is that easy.

Thanks to Vodafone for their free support helping unlock my phone.
