My blackberry is failing to boot - Cell Phones

remove the battery and try to reboot again if it still fails buy another battery the one you are using is dead.

the device is drained to the bone this should go away and boot after 30 minutes max. I'm assuming you are using the original blackberry charger using a charger that fits but doesn't match the voltage/amperage that the blackberry charger outputs you wont be able to get rid of the drained battery screen if your blackberry haves juice you can use a non-approved weaker charger but that screen means it needs the original....also the blackberry USB is lets the same amount of electricity

Try taking the battery out for 30 seconds and putting it back in. You may need to restore the firmware using blackberry desktop manager on your PC or Mac if the problem persists.

You can get the unlock code for Blackberry 9700 Bold form UnlockGenie.com

There code will never fail.

my blackberry bold 9700 turns on and boots but keeps restarting by itself

Try to restore the blackberry without the battery inserted. Google instructions on how to upgrade the BB firmware. Does the device seem to boot normally, but with a white screen? Then it's a broken screen. Does it not seem to boot even after the firmware restore or the restore error out - then it's a broken motherboard. Both can be replaced fairly easily. Here is an Blackberry Repair Guide that shows how to open a Blackberry. If you want somebody else to do it for you go to Blackberry Repair.

Try doing a handheld wipe.... Bad side you lose everything on the phone (contacts,messages,pictures)

good side you get your phone functional..

Here is how...

Hi, have you solved the problem??

if yes, please tell me HOW.

thx

Cause:
Some of the boot up file has got corrupted

Resolution:
Re-install the handset software using Desktop Manager

I would download the latest Blackberry OS from Blackberry.com and install it via the Desktop Manager. You can get the latest OS from this URL:

You can find the model by removing the battery and it should be on a sticker.
