OK this is far from my first upgrade but when I run AppLoader or DM the software I want to upgrade to doesn't show up. I followed all of the steps exactly (as usual) but this is the 1st time this has happened. My 9650 currently has the 507 error. Someone please help. Also I tried uninstalling the software and reinstalling. Still no luck.

As long as you've deleted the vendor file, it should work. Run a scan to see if a ghost copy was installed. Is it reading the pin #?

Does anyone HAVE a roll-back copy of OS4.6 for a Telus Pearl 9100?
Mine got deleted when my computer crashed and they were unfortunately not backed up on my harddrive.

I own a metroPCS curve 8530, I want to install the latest OS (Sprint), if I install this OS will I loose all the native metroPCS apps?

If it's a MetroPCS branded phone you should be fine. If a Sprint unlocked phone is flashed to MetroPCS or Boost, there can be problems when it's upgraded.

I am also looking for direction as to how to downgrade from OS6 to OS5 on an AT&T 9700. I am not interested in using programs that will void my warranty.

How to roll back to OS version 1.0.7.xxxx after install OS Beta 2.0


Here you have the steps I tested in order to rollback the BlackBerry Playbook to OS version 1.0.7.xxxx after installation of OS Beta version 2.0.0.xxxx

After install the Beta version 2.0 you will need to re register the Playbook on website



1- input the PlayBook PIN number , accept terms and conditions and now we have to wait more than 24 hours ( not less than 24 hours, it is important ).

2- Once the waiting time is gone we need to perform a security wipe ( during the initial set up no updates will be shown as available ) and after finish the process only the browser will be shown on screen.

3- Using a Windows based computer ( PC ) with the BlackBerry Desktop Software previously installed on it. ( I haven't tried a MAC computer since we don't have this option available here, but since we only need to run an update it should work)

a) Connect the PlayBook using the USB Cable and you will get some information on BlackBerry Desktop Software showing that updates are available ( 1.0.7.3312 ) run updates and wait until process is done.

b) Wait until download finish , restart the PlayBook and done!

c)After reboot the Playbook just check OS version installed ( should be 1.0.7.3312 ) and check for Software Updates, and you will see the next message: "You currently have the latest software installed" if process was correctly performed the message for update to OS 2.0 will be no more.

Try uninstalling and reinstalling all the BlackBerry software. It's either an issue with something there, or you need to replace the USB cable.

I just looked at at&t's site, and they have several OS5 versions available for the 9700.

Thanks:d:d

Wulf, in the OP it may be a good idea to note that sometimes there may be >1 vendor.xml files generated when an OS is installed. IMO it's common enough to be noted.

See step #6 in advanced, where it would be required except with most leaks.

Yes, but it only points to the most common location for the vendor file. (Too) often there are copies generated elsewhere on the hard drive, and if not deleted, the OS upgrade does not go through.

True enough, thanks. There are a few other locations a second can hide. I'll do a little editing.

Desktop ahould recognize the phone, but I wouldn't use it unless on BES anyway. Use Loader.exe, after deleting the vendor.xml file, both found here:

•64-bit: Computer/C:/Program Files (x86)/Common Files/Research In Motion/AppLoader
•32-bit: Computer/C:/Program Files/Common Files/Research In Motion/AppLoader

If Loader doesn't recognize the pin, take out the battery, reconnect the phone and start it again. When the process starts put the battery back in.

Worked like a charm.. Thanks.. But i realised, i'm not lazy enough to run a script.. what i did was, 1. goto my computer, 2. open the OS drive, 3. click F3, type vendor.xml , 4. delete all the files that had the path that was anyhow related to bb.. and the installation for .723 then worked awesomely!!

Thanks @BigBadWulf !!
