I tried to do the same it doesnt work
 

I downladed S/W from At&T bothe Desktop 4.0 and OS4.0 for 7200 devices (My device is TMO).
I deletet the Vendor XML, nothing works .. Help

Here what I did, from a clean system w/o BlackBerry Desktop Manager.

1. Perform a clean uninstall via BB KB KB-02206.

2. Install BlackBerry Desktop Software v3.6 [SP3](Click on download link at the bottom of the page)

3. Perform a FULL device BACKUP!

4. Download and install the BlackBerry OS 6230_6280-v3.7.1.41_P1.6.1.41 (6230 Handheld Software Bundle 3.7.1.41)

5. Perform a FULL device BACKUP!, name it something different.

6. Download the AT&T BlackBerry OS 4.0

7. Erase the vendor.xml file, or rename.

8. Install the AT&T 4.0.

9. Install Berry 411! (Mad props. to Phil Bogle, I love it!!)

Please note, this worked for me, might not work for you.

If you get an error msg. or something post it.

Doesn work
 

Did all that and more tried it with desktop 4.0 , tried it on a new computer doesnt work, i see the two directories in common files but it does load the 4.0.

Help any idea hwo to work around it ?

Well, do you get an error msg? anything?

NO
 

Nothing everiting working fine, it only see's the 3.7 version, when i run the loader. in the desltop help/about i see both versions.
(my setup is desktop 4.0 )

I don't believe you can upgrade to Blackberry OS 4.0 (device) w/ Desktop 4.0 (PC) installed. Please read my directions as posted, and follow them, let me know how it works.

I did it with 3.6 (SP3) tried it on anew computer (and my own) did'nt work.

507 error, I have a 7230..I used the 7230 package..any ideas?

I found a handful of KB articles at the offical RIM blackberry site about that error.

Check them out.

Search for:

507 means No Operating system on the phone.

That tells me you are not finished with the upgrade.

You must have unplugged the phone before it finished.

Plug the phone back in and rerun the upgrade.

I left it there for an hour and then the software came back with an error.

Care to enlighten us to which error it was?

error 507.

You are going to have to try the load again. If you are using a USB hub, try and connect the BB directly to your PC or laptop.

Start Application Loader and see if it will try and load again; if not, you must get a copy of javaloader, type

javaloader -usb wipe from a DOS command prompt

to wipe out everything on the BB; then restart Desktop Manager.

You may have to delete Vendor.XML

I receive a 507 error, on the step that says "reconnecting to JVM" and at the end of the process, app loader aborts and says "unable to reconnect to the handheld during a multi-stage load operation"

any ideas?

Thanks
 

Worked like a charm for me... Thanks for the DIY. :D
