    Downgrading from 5.0

    How do you downgrade your OS from 5.0 to .151. I tried to delete from desktop and reinstall .151 then use app loader but it won't recognize the OS change. It only gives me app change possibilities

    Is it asking you to downgrade? If so that is the option you would select

    Also are you deleting the 5.0 os through control add/remove? If not do so through there, the reinstall .151 and run loader. It should ask you if want to downgrade your phone.

    Hello John,

    I would suggest to install .75 back onto your DM, install to your 9530.
    Verify that the .75 OS took to your device. After the confirmation, uninstall .75 from the DM and reinstall .151.

    What do you think?

    How I did it was. I wiped it clean with BBSAK. Uninstalled 5.0.Then went into the program files and removed all of it. Installed 151 then installed 7.1.4 from Crackman. Then deleted the venor file and copied the new BBM files in to that os. When I hit the apploader. I got the "downgrade" message. I clicked ok. I am back on 7.1.4+151 with the new BBM and all my apps are working. Hope this helps
