:frown: I Have a problem when I switch my mobile phone to it's Browser mode ,
After a period of time ( 12sec , 9 sec , it's different at each time... ) the LCD goes off ( The Light Of he LCD Goes Off , but the screen is still on ) , and it switch the Current application under running ( ex : Snake ) into the background ( no matter what it is ) , and it brings the screen into the main "Menu" ( I mean the main Screen that shows the wallpaper , battery , etc ... ) .
the buttons are still working , and i can go back to the application by swithching to it ( By Holding The menu button ), but the light do not come back ( but sometimes it comes back but it goes again and do not come back ) . it's been like that since i bought the phone . i have removed application like pinball , or Wayfinder , but the problem is still there .
and another question , can i Delete Everything in my phone ( Symbian included ) and reinstall it ?
Deleting everything and installing the os of my Mobile Again .
( my english is not good , hope to have been able to explain myself )
Thanks In Advance For Your Help.

Not had this problem. you cannot delete everything including symbian from your phone. you can however, do a full format which will wipe EVERYTHING off your handset, and it will be almost as if you have just taken it out the box. (but hopefully without your problem).

to format, make sure your battery is full (just to be safe) then turn off the phone. hold down buttons "3" "*" and "green/call" then keep holding and turn on phone. hold all four buttons until you see the word "formatting" on the screen. after about 3-5 mins your phone will be fresh as a daisy.

for a better explanation of how to format, go to this link:

its for the 6600, but should work for the 6260

if this method brings back the same fault, take the phone to a nokia service centre and get the firmware updated.

good luck.

I've Tried Formatting , But It Didn't Solve The Problem ,
1- Is There Any Way To Uninstall And Reinstalling a Symbian of a mobile phone ? ( 6260 )
2- If No , Is there Any Way To Upgrade It ?
Thanks In Advance For The Replies

there is a way, its called taking it to your local nokia service centre to get the OS re-flashed. they may have a slightly newer firmware version, that should sort you out!
