Question 7100T will not boot

Please Login to Remove!

I have a Blackberry 7100t for T-Mobile. No matter what I do when I power the device, it will give me a perpetual hour-glass, and never boots up. Some suggested that I use the JL_Cmder utility to wipe the OS:

C:\Program Files\JL_Cmder>javaloader -u wipe
RIM Wireless Handheld Java Loader

Connecting to device...

However, this utility can connect to the device. After a half an hour, I got a timeout message stating that utility can not connect to the port. Below are options I tried:

1) Removed the sim card, and plugged the USB cable to the device that is connected to the computer.

2) I tried #1 and also removed the battery

3) I removed the sim card, battery, and the USB tether from the device for a couple days in hopes that the device would lose it settings info and reset itself being that it had no power. That didn't work.

Is there anything else that I should try to revive this device?

Give this a shot


Wipe device with JL_CMDR before doing the following


1. Install Desktop Manager (You can skip this if it is already installed)
2. Install firmware package for your device on your pc (You can skip this if it is already installed)
3. Make sure Desktop Manager is not running
4. Start loader.exe for C:\Program Files\Common Files\Research in Motion\AppLoader
5. Click on Next in the Application Loader window
6. Remove the battery from your BB
7. Connect your BB to the USB cable
8. Reinsert the battery
9. The drop down list "Connection:" should now change from COM1 to either USB:UNKNOWN or USB:[BBPIN]. As soon as you see "USB:..." click on Next and Application loader should be able to reconnect to your device. Now you can reload the firmware.

As timing is important for this procedure, it can be possible that you will need to try multiple times Good luck
