Thanks, I guess I have to be patient.

great tutorial!

Sweet...isn't 64 bit compatabile..

Windows 64 bit? Use Desktop Manager 4.2 SP1

Ok. Could bu I can't download lates OS because im live in Poland. I haven't numer to T-Mobile (My phone have T-Mobile SimLock). Could You send mi form e-mail latest software for 7100t ? (my email: )

JL_CMDER is NOT 64-bit compatable. Desktop is...

JL_Cmder only takes about 30 seconds to run. If it won't work then just find a windows XP machine to run it on. Then connect it to your Vista or 64 bit machine. You need JL_Cmder or javaloader to wipe the device.

Will java loader truly set device back to factory. There won't be ANY email remnants in the OS? Trying to determine which wipe process will truly wipe the OS, or do file remnants still exsist?

will this work on a 8700c?

Hi All,

Can anyone help. I have an 8700 that just keeps rebooting, showing the timer and then shutting down again continually. I have seen this listed elsewhere on these forums and the advice is always to wipe the device and reinstall the OS. I have followed the good advice in this thread but when I try to use jl_cmder to wipe the device it won't connect. I ahev tried using javaloader as well but same error. I am stuck at this point. Does anybody have any advice?

i tried this and it didn't go back to perfect factory. I still don't have the 4 bluetooth services needed for bluetooth synchronization.

does anyone know if this will work for an 8703 from bell?

Yes.

I had installed 4.2 OS and wanted to downgrade back to 4.1 OS due to the keylock bug in 4.2 OS I had. I followed the instructions but when I plugged my Blackberry to the computer as instructed nothing would happen. It did not prompt me to install the older OS. After many uninstalls and reinstalls by repeating the step I found out that I needed to load Application Loader in the Blackberry Desktop Manager in order to begin the install for the older OS.

I had to load Application Loader and then click on the instruction on loading the older OS (I forgot the exact wording.) I hope this helps other people in the same situation.

Correct. You aren't promted to "downgrade" as you are to upgrade.

Hi John,

I had an app errror 205 so i did everything as you described above. I have error 507. When i run the Aplication Apploader, it opens Aplication Loader Wizard and there is this message:

The BB Desktop Software does not have BB Device Software for the device that you have connected to the computer. Contact your wireless service or system administrator.

The screen on my BB shows the picture of the PC and the phone with 2 arrows in between that are not moving.

What should i do? where is the problem?

Thanx Barbora

sounds like you need to load your specific device OS to your computer

Ok, i have BB Pearl 8100 and that is what i downloaded. i tried it with the newest desktop manager version and when it didn't work, i uninstalled it and tried the old version from the cd that came with the phone. the result is the same. now i have the new desktop manager again, but it isn't working.

I also tried to go to t-mobile, they sent me home to try to figure it out by myself. So i tried, it didn't work, so i called them. Talked to one girl, she didn't know anything, kept me on hold, then finally transfered. So i talked to another girl who couldn't help me, waited on hold, at the end was transfered again to an automatic system where non of the options offered applied to me so i tried one of them but was on hold so after 1/2 hour i hung up and now i am trying this forum.

Barbora,
There are two pieces of software required in order to get an OS back on your phone. Error 507 is good. That means the device is ready to have an OS loaded to it.

Install the newest version of the Desktop Manager.

Then go to TMobile.com and download the Handheld OS package and install that to your PC. This is 'in addition' to the Desktop Manager.

Once both are installed to your computer simply plug in the BB, open Desktop Manager and run Application Loader. It will detect your device and load the OS to the device.

Good luck.

~John

I have my BB back! Thank you John, you are the best! :o)))

Great!!!

Will The JL Cmder And Os Reload Work If The Keypad Is Locked And I Forgot My Password For The Keypad Lock?

Enter the password incorrectly 10 times (follow the prompts) and it will wipe it out for you.

Hey guys,

i have an 8703e that i am trying to wipe but what it does is.. Red light will come on, then screen comes on to hourglass, it will stay on for about a minute, then shut itselft off and reboot. When i try to connect ANY of the blackberry software to it, i get connection errors because the Blackberry is usually either starting up or shutting down. That cycle runs between 30 seconds to about 2 minutes sometimes. What can i do?

i have tried:
popping out the battery and replacing it
ALT-CAP-DEL
ALT-CAP-DEL x 2
connecting with the Device manager
connecting with the Handheld manager
connecting with the Java Loader

I tired the process above where i downloaded and installed all the pieces of software, but when i go to connect the device it bombs out everytime.

any ideas or help is welcomed!

thanks guys,
RPM

Welcome to the forums...

This usually fixes that problem:

What to do next if Jl Cmder will not connect and wipe - BlackBerryFAQ

thanks, man... i will try that out..

-Rpm-

Ok i tried that and it started the process ok, but as it was loading the new OS with the apploader, the blackberry rebooted and now i get an error that says:

JVM ERROR 545
file system corrupt

It seems to reboot every 60 seconds now.. i think the device is just hosed..

I am getting ready to sell an out unit. I followed the instructions and used JL_Cmder to wipe and got the error 507, which was correct. Then I installled device software back on. Everything looks clean and brand new in the unit but it still shows my old cell number in the phone mode under "my number". Is this normal? Or have I not really wiped it afterall? Thanks!

I would assume (cuz I don't know for sure) that that will change when someone activates it on another line.

I tried this on my Blackberry (It's 8700g from T-Mobile, unlocked to work on AT&T) that I bought on TigerDirect and now everything works but it says I don't have a sim card. I'm guess wiping it out screwed up the Unlock code.

No what? Do I call AT&T since they're my carrier, T-Mobile 'cause they sell the phone, or RIM 'cause they make the phone.

TigerDirect says they'll take back the phone and send a new one but I really don't want to wait 1-2 weeks for another phone to arrive.


Can anyone help? >_>

You cannot "wipe out" the unlock code. Once a phone is unlocked it can never be locked again. Something else is wrong. What exactly does it say on the screen? is the sim inserted correctly?

It just says insert sim card, but the sim card is in right =\



EDIT**
I feel stupid now, but you were right. I had the sim card in wrong. Must've put it in wrong earlier when I took it all out. Thanks for pointing this out to me before I paid 20+ dollars for a new unlocked.


Extremely happy now, I just got my phone today and I can't imagine not being able to use it. Thanks so much. ^_^

i tried this and it is still got the hour glass spinning and the white background and it is not going any further

What exactly did you try?

Can I use Jl_Cmder to wipe an Alltel Pearl and then use the Verizon installer of the OS to make it work on Verizon?

You can load any OS to the device you want to (as long as it's for the 8830.) However, you can't use an Alltel device on the Verizon network no matter what you do to it. Verizon doesn't allow it.

What do you mean they don't allow it? If it is loaded with a VZW OS wouldn't everything be set to system b, correct PRL, etc? Are you referring to the VZW not actually being able to activate it in their system?

I have flashed other model carrier phones over before. The ESN is loaded in our system correctly as a 8130 Pearl.

hey guys, question? can i use the jl_cmdr for app err 205 issues?
i was updating my os when it ddint push thru, next thing this err msg pops up and now im stuck with it, trying to wipe my unit but it aint workin as of now.
