So i've persuaded o2 to have a look at my phone in the hope of replacing it. First they've asked me to reset the phone using *2767*3855#. If i have the same problems (dialpad not working during calls) then i've to return it. If their engineer cannot fix it, i'll (hopefully) get a replacement. So i'm running Galaxo with JC6, what should I do before returning the phone? I'm thinking Nandroid and then copy everything to my hard disk and remove that from my phone. Then use ODIN to install the latest official firmware (which is??). Then I run the reset command they gave me. That about right or should I do something else? Any help or advice appreciated.
