My samsung blackjack 2 will not charge. the battery is now totally dead, will not turn on and will not charge even with the wall outlet charger or the computer usb charger. when the phone still had some charge in it and I would plug it in to the charger, it would constantly beep and red light would flash.

If the Red Led stays turned on it is as simple as this.....the solder connecting your power on button to the system board in your phone has worn off..... you must pop the power button at the top of your phone off and you will be able to see where the soldering paste has simply worn off. At my job I have a soldering machine so it was not problem for me. I simply took pasted it back to the board with tin.....now this may require some work. just pop off the top section of you phone with a flathead screw driver and pop out the power button. look closely and you should be able to see where the botton has lifted from the little greenish system board..... Find someone to solder it, put it back together and it works like new.........SEE YA

Apparently this is just a bug with many of the Blackjack II's. I have the same problem and I have read on forums that many others have had the same issues.

Same problem with mine. I have even replaced the phone and the battery and the problem still exists. I had another battery software installed and it show that the phone thinks the battery is fully charged and just wont charge anymore, even thought the battery bar is not even full and the Windows Mobils OS says that is battery is not fully charged.
