I am actually having the same problem with mine-- if I find a solution, I'll let you know. It was fine last night; I turned it off and plugged it in because it was nearly dead, and this morning, it won't turn on. I've even tried switching batteries.

ALL MY PHONE DOES IS FLASH LG


Try going into the stock recovery and then plugging in the charger. To get into the stock recovery: Pull battery. Hold power button for 30 sec to clear the phone. Hold home + volume down button, then power button (All at the same time) until you see your android recovery screen. Then plug phone into charger for 30min. Unplug charger, then select reboot system. Once rebooted finish charging.
If this doesn't work then you could have a defective battery, cable, or wall plug end.

Hello, why the phone is not charging is because the cell of the battery is weak and can power on the phone for to long, that's why it shots down so quick,

You will need to replace battery with a new one for longer talk hours.

Make sure you charge battery for 6hours before use.

And also if the battery still doesn't work that means the phone memory is weak and it will need to be flashed to restore back the phone memory.

What you will need to do is this,

You will have to flash the phone to restore the memory of the phone.

I hv a blackberry 9000 phone and the red light blinks but I cant switch on the phone even thouh its connected to a power adapter for charging


Hi,

Take the phone off charge and take off the battery on the phone, you can now put the battery back into the phone. Press and hold the red power button on your phone. If the problem persist then go ahead and download the blackberry desktop manager unto your computer. Connect your blackberry to the computer and initiate the blackberry desktop manager. Once it shows connected as status between the phone and your BDM (blackberry Desktop Manager). Reinstall the software on your blackberry. Make sure the computer is connected to the internet.

Help ME!!! V3i dead Now!!!!


Once you flash the v3i to R441D you cannot go back to R397 but if you power on phone while holding down # and * you can go into bootloader mode and then use FlashBackup to re-flash phone with R4441D firmware. I have had this issue a few times and always been able to recover it. If this doesn't work locate someone in your area via google or craigslist that offers Smart-Clip service and they can fix it for you.
