is it possible to downgrade the firmware of a Z10 back to a version 10.1.?
We habe problems with 10.2 in combination with Exchange 2003. 10.1 is working perfectly. As long as our new Exchange Server is not ready I would like to downgrade our the devices back.
Does somebody know if it is possible?
Thanks and best regards

Hi and Welcome to the Community!
Try this process:
This requires you have a a Windows PC computer.
When the installation has completed the BlackBerry will commence the boot process.

I think I tried the steps as suggested (not sure), but at the end the BB will wants to install the latest offical available version from 10.2.
But I need to reinstall a Version 10.1 again.

Sorry, but I'm absolutely frustreaded. There is a problem with the OS 10.2. on our devices, and Blackberry is not able to give me a simple rollback to an previous version of 10.1.
I asked a similar question over the BlackBerry Expert Support Center portal and there I have also no response.
All devices with 10.2. have problems with the calender sync. All devices with 10.1. have no problem.
The simple solution from the people which are sitting over me....
...stop the blackberry 10 rollout, affected users will move back to their old blackberry device. The next step I have to do is to check the implementaion of iPhones.
Sad but true.

Good for you mstuhr...maybe on the iPhone you will not get the run around. I have been over the last 2 hours searching on this forum how to DOWN - GRADE the z10 OS. Sorry for the caps but it seems there is major confusion between down-grading and UP-grading. Every solution given on this forum results in an UPGRADE. I am suspicious and curious as to why RIM will not supply a proper solution for a downgrade. Even after restoring my z10 using the LINK, the z10 phone setup goes into automatic - uninterruptable update mode to 10.2.1.2122.
