I got a problem .
-after i took out my back cover on the n91 while the phone is ON..now the phone juz cant boot up with the back cover .

-it will only boot up if i take out the back cover.but i cant detect the hard drive without the back cover.when i put on the back cover while trying to format the phone ,before i can start the formatting the phone ...it juz went auto off and on but fail to start up.

ANy remedy for this ???

Remove the battery and anything conected to the phone, Hold down the power button for 1 minute, then put the battery back in, put the cover back on, plug in the power, then turn on the phone. Let it charge as normal till its full.

Take it in to a service center to get it fixed if it doesnt work.

You may already know this, but NEVER OPEN THE BATTERY COVER WHEN THE PHONE IS ON, IT WILL DAMAGE THE HARD DRIVE IN THE PHONE!!! it says so in the manual and many websites.

it juz cant work .......sucks.

tks for the help

Go to a Nokia Service Point. Now days, I think, thtat N91 is the more sensible of Nokia Phones, cause the 4Gb disk!
