Problem downgrade from leak 7.1 to 7.0
Hi! greeting guys
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
Need help plz! - 06-14-2012, 07:42 PM #2
You can't downgrade your OS from the phone.
The simplest way is to hook up to Desktop Manager, hit Update, select View Other Versions, choose an OS from the list, and agree to the downgrade.
