Any help will be GREATLY appreciated. Last night my BB8100 phone shut down while upgrading to latest software from Tmobile.

I've tried JL_Cmder to wipe it but it's not working. I typed in wipe and blackberry at least 20 times, and nothing happens. I also tried the 2nd instructions (the ones the FAQ's suggests to try if the 1st doesn't work) and that's not working for me either. There is already a command there which it won't let me erase, and when I try to type the one it gives me (C:\Program Files\Common Files\Research In Motion\AppLoader) it givs me some type of message saying it doesn't recognize it.

Any input would be GREATLY appreciated. please please help me!

Thanks!

You are going to have to locate a program called "Loader.exe" on your PC C: drive. On PCs it is normally in c:\program files\common files\research in motion\apploader

You have to find that - it you can't you can not proceed. It gets loaded onto your PC when Desktop Manager is installed.

Once you find it, you open a DOS prompt, and with the BB connected, you type

loader -nojvm

You must be open to the directory (use the CD command to get there).

I have again learned something new! Thanks NJ!

What, exactly, is your BB doing? Is it giving an error of some kind? Is it giving a spinning hourglass? Is it turning off and on?

A couple of DOS hints:

type cd.. to move back one directory. Do that until you get to just c:/

Then type cd Program Files\Common Files\Research In Motion\AppLoader

John Clark: it isn't doing anything! Nothing at all! Totally black and shut off. There is only the red light blinking.

Thanks NJ I'll try that now. God I hope I can get though this.

That doesn't sound like what happens when an OS upgrade goes bad. The red light is blinking but the screen is black? Is the LED flashing steady? It's not in standby, is it? Press the mute button on the top of the device or press the red phone button.

Usually, when an OS upgrade goes bad you'll get a white screen with one icon in the center or a white screen with a spinning hourglass or a loop where it spins, then turns black, then spins again.

I have tried pressing those buttons but it doesn't turn back on. It won't come on at all. What is the LED light? The red light is flashing 2 tims in a row every 2.5 seconds. If it were in standby, is there any other way to wake it up? I've been pressing all buttong for 24 hours and I'm really going crazy.
I just don't understand what happened.
I really appreciate all of your help!

LED = the red light on top. It stads for Light Emitting Diode. Just some jargon.

We can't tell you what has happened as we weren't there for the software upgrade.

You need to open a DOS Windows - select Start / Run and type CMD in the box and click OK.

Then, using the CD (change directory) command, go to the directory that John Clark outlined above. Then type

loader -nojvm and press the enter key

Let's see what happens

I'm still having DOS issues. Ok I was finally able to ge tto C, but it showed exactly as " C:\>" As opposed to just "C:\"

Then I typed in execatly " cd Program Files\Common Files\Research In Motion\AppLoader" then hit enter. it said it doesn't recognize it.

c:\> is the same as c:\
Try this

at the c:\> prompt, type

cd \program files and then press enter. It should now read c:\program files

then type

cd common files and then press enter

then type

cd research in motion and then press enter

then type

cd apploader and then press enter

The prompt should now read

c:\program files\common files\research in motion\apploader>

Now type

loader -nojvm and press the enter key

Phew..

Thank you so much. While doing this should the blackberry be connected?? And should the battery be in?

Yes.
Yes.

The suspense is killing me! Did it work???

OMG i think it's about to come back to life!. I got passed DOS and it said the software was successfully installed. Now the white timer is on the screen and spinning around. The phone is still connected to PC. Should I dissconnect her now?

The screen is just white with timer spinning.

DO NOT DISCONNECT IT.
LET IT SPIN - it can take up to 15 minutes to come back.

Do you have a backup of your data (address book, calendar)?

OMG the welcome screen is here!!!! Should I disconect now????

As far as the backup goes...last time I updated my software I think I recall me clicking an option to back up data. If that's the case, would it be somewhere on my computer?

i told you NJ knew what he was talking about!

There should be a backup file "something.IPD" on the hard drive.

Do not disconnect. Start Desktop Manager (if it is not started) and kick off the Backup/Restore icon. Click Restore and see if it finds the right backup file (it will have the date in the file name).

Shhhhhh.
