    Recently I bought a z10 (10.0.10.648)
    I upgraded it to 10.2.1.3247 but since then I have problems with my company's wifi network
    error......unable to authenticate against network..............The problem is that I cant have access to company's router

    Is there any way to downgrade to 10.0.10.648 ? I had no problem with this version

    Many thanks for your help

    BlackBerry blocked the installation of older OSs (all 10.0, and 10.1.0.1482 or lower) because of some security problems. However, you could try reloading 10.2.1.3247 with BlackBerry Link and see if it fixes anything.
