Sony ericsson p990i

1. my p990i displays a replace main battery message when i switch it on and when the power menu appears, the power selector moves but it doesn't select power on or flight mode. i have tried with other sim cards it works fine and my sim card on other phones works fine as well. How do i fix this?

2. in trying to fix the problem, i did a master reset and formatted the memory stick and in ther process lost all the files that came with the phone. How do i restore my phone to factory settings even with deleted files.

    Suddenly ran out of battery power. Charged and tried to restart. Received "change main betteries" message during start up. Tried three new batteries. Same problem. After numerious attempts the brick decides to bootup without the error. Cannot find any assistance. Nice brick.

Replace main batteries


Hmmm....This problem normally occurs when u use duplicate batteries available in the stray market

Please try to get good ones...

1. If u think that u already have the right batteries, please check ur charger unit...try with a similar one in working condition

2. Check the contacts, on the phone and check for all visible damage on the power lines on the board/ phone

3. If within warranty period, i would suggest u take the phone for a good overall checkup

Try to tell me.... whether my suggestion was useful???

Bye

:)

Have a nice day.
