H,you can reset the phone,might restore lost icons.
Note: you will have to backup data cause data might be lost when reset is done.
There are three main types of Reset that apply to the Blackberry. These
are listed in order below. Instructions for Blackberry Pearl are
slightly different - see bottom section of the Tip.
1) Soft
Reset - simply press the ALT+RIGHT SHIFT(CAP)+DELETE keys.
This
reset stops all applications that are running on the Blackberry and
will help if you are having problems connecting the device to computer.
This reset will not erase any information from your device.
2)
Double Soft Reset - this reset is almost equivalent to a full hard
reset. First perform a Soft Reset as outlined in Step 1.
As soon
as the screen is no longer black - repeat the steps once again exactly
as before.
This takes you to another screen showing an hour
glass. Allow the device to reset. This helps if the device has suffered a
more serious error. Be aware you may loose some information from your
device. A backup is advised prior to proceeding if at all possible.
3)
Hard Reset - this is the full blown reset and will fully reset the
device to help resolve critical errors with software or hardware. Again
back up important information before proceeding if possible.
Note:
For RIM models 850, 857, 950, or 957, you must insert the end of a
paperclip or similar blunt object into a small recessed hole on the back
of the unit and depress the switch inside. The device will reboot and
be hard reset.
Other Models: With the device
turned
on - remove the battery for 30 seconds or more. Now replace the
battery. The device will reboot and be hard reset.
Blackberry
Pearl: To reset to factory defaults enter 'Options' from the main
menu. Scroll to Security Options and press the trackball. Choose
'General Settings'.
Press the left soft key, then scroll to "Wipe
Handheld" with the trackball and press the trackball. To initiate the
factory reset, your phones security code may be required in order for
the process to complete. Your phone will now be restored to its original
settings on leaving the factory.
A hard reset can be achieved
with the Pearl in the same way as outlined at Step 3 by removing the
battery.
Be aware that resets such as these may erase data,
such as contacts, ring tones, pictures, text messages and stored
Internet files and emails. Make sure to back up important information
beforehand if at all possible. You can obtain software to back up the
device to your computer directly from Blackberry right here.Hope this Tip helps. If so
please do leave a vote for the solution.
Thanks.
