how do i downgrade my bb9900 from leak os 7.1 to 7.0. I bought a second 3500mh battery and it doesnt work with the latest OS.
I tried to downgrade the OS from the phonemeny but i dont have the "downgrade" button in "options, device" on my blackberry desktop manager
I do hit the update and trying to view other version . But seriously there no such a thing like that anymore when i connected my phone to desktop manager . But when i trying to connect with bold 5 (my dad's phone) . And i can find the option to downgrade but when turn to my bold 4 , I cant find it to downgrade .
