suddenly cannot log in with Google account

[#1]

Hi, I just bought my Xperia X10 for 2 weeks and it was perfect (google market, gmail, gtalk all working),

until yesterday when I get a new cell number for xperia but in the end i revert back to my original number,

and when i accessing something that requires google account (market gmail gtalk etc)

all requires me to input my gmail password, and when i sign in i got a network error

then i started to look solutions on internet, they say i need to delete my google account and set it from zero

I did it, but now i get something like "There is a temporary error or your sim card is not provisioned for data services"

Another solution is to do factory reset, so i reset my xperia, do everything from zero

No differents, "There is a temporary error or your sim card is not provisioned for data services" still comes up.

i am confused, my phone working perfectly on internet, both wifi and EDGE connection (china dont have 3G yet)

i can use operamini and xperia browser to browse internet, and even chatting on msn and such,

but i need Android Market  :S

any solution???

Download SESU, install in your PC/Notebook, run the software and follow the onscreen instructions, Switch off your mobile, connect your USB cable while holding down the back button. Once you get a message to release the back button release it. If you get a message saying your software is up to date, do a repair.

That should be able to resolve your problem.

Hi, Prathaban! Thanks!

I'm not sure what is wrong with your handphone, but I've read this in few other forums and many have told they resolved by repairing the firmware.

You can download the SESU from here.
