My phone developed a habit of switching off - 24hrs later it will not switch on.
Checked its battery in another handset - no problem.
Cheched a working handsets battery - still would not switch on.
I have attempted to follow KB1044 "How to force the detection of the BlackBerry smartphone using Application Loader" and can only get as far as "reconnecting to JVM"
At this point I get a Connection Prompt telling me "Application Loader unable to connect with your device. Please re-connect, enter the password, if required, and click Retry"
Have tried this numerous times but cannot get past this point in the process.
Have restarted the process without success.
Have tried installing a downgraded OS without success.

Search and download your OS and all the above applies
Nevertheless, here's what I suggest...
The simplest way is to, on a PC (you cannot do this on MAC):
Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below. (This is probably moot given the errors you have...it's likely your data is already gone from your device, which means you must now rely on a backup you took before this happened.)
2) Uninstall, from your PC, any BB OS packages
3) Make sure you have the BB Desktop Software already installed
4) Download and install, to your PC, the BB OS package you desire:
5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
6a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.
6b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:
If, during the processes of 6a or 6b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.
You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.
You may also want to try the "Bare Bones OS Reload Procedure" to attempt to narrow down the precise causal item:
When the behavior presents, you know the culprit...the last thing you loaded.
If the behavior does not re-present, then you know that either step 1 or 2 cured it.
If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.
You may also need the use of these tricks:
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:
Good luck and let us know!
