The blackberry pearl 8100 turns off by itself and than the red light just blinks 2 times stops and then 3 times and then repeats. it will not turn on unless i connected to the charger.

Your Blackberry probably just needs a firmware restore. Here's a guide on how to restore the blackberry firmware, the website is at : Restore Blackberry to factory settings. Download the Blackberry Desktop manager and run the application loader. If it asks you for a password, you can enter it 10x wrong and that will wipe the blackberry as well.

It might be a software issue, You need to walk into the service center.

your battery full down plse seprate boost battery 6v before recharge phone

Go to nearest service centre..since you have tried alll trouble shooting steps.

did you format the card first... this might help. It could be too much memory. I put an old SD card in from a former phone and it was doing the same thing...powering on and off repeatedly.

Red light usually means low battery so leave it for a hour or so red light should stop.

try t-mobile.com/bbupgrade... im not sure it'll work but that what they are tellin me bcuz i have the same problem

Hi
1>There should be a red blinking light because you have a text message waiting
2>Deleate messages from your inbox cauz it is full
3>Next time you'll see it saving the messages

Try removing the Sim card and re-inserting it.

My wife and I both have Pearl's. I found that the problem on both of them was caused by Color Pearl, an application that allows you to change the color of the Pearl's trackball. It was not a problem until upgrading the Blackberry software to v 4.5. I tried rebooting, removing the battery, etc. The light always came back on after an alert. Removing the application ColorPearl did the trick. Just go to Options>Advanced Options>Applications and delete ColorPearl. Hope this helps someone.
