I bought a Blackberry 8800 and when I put the battery in, the LED lights up once and there is a battery with a red line going through it on the screen.
I tried recharging it for hours and hours - nothing happened.
I also bought a new battery, but the result was still the same.
Then I decided to do a clean software installation using AppLoader using the command prompt with the /nojvm command but on the second step it said that it was "unable to connect to the device" so I went on and tried it without the /nojvm command and the same thing happened.
After that I downloaded Jl_Cmder and tried to wipe the software, but it didn't do anything. ( I chose option 4 from the menu and then I entered blackberry when prompted, but I just got redirected to the main menu)
So now I am out of ideas... please help me out. Thanks.
Let's back up. Sounds like you didn't actually connect to the blackberry and even get a wipe started, correct?
Plug the blackberry into a wall charger with the battery in it. Start with the "new" battery that you just purchased. Wait about a half hour or so. Then remove the battery for half a minute with the blackberry still connected to the charger, and then replace the batter. Does the blackberry then boot up? If so, let it finish charging.
Did you download and install the blackberry desktop software on your computer? If not, do it and then come back.
Next, plug in the blackberry to the computer using the usb. Don't use a usb hub or keyboard usb connector. Do as I suggested above. Wait a while and then remove the battery for a moment and replace while the blackberry is still plugged into the usb. If the blackberry boots up, let it finish charging. If it doesn't and you still see the no battery symbol, wait a while longer and try again.
Yes, the desktop software is installed on my PC and the 8800 4.5 firmware is installed too.
I did plug the USB in the main port at the back of my laptop and repeated the technique that you suggested 3 times in a row with a 5-10 second delay between the battery replacement and it ended with no luck. The same icon appears.
I did buy a brand new battery and I tried to charge it, but with no luck... still the same thing. =)
It didn't power on properly with the charger plugged in too. It must be a hardware fault, but oh well. =)
