Default Downgrade OS

Please Login to Remove!

I recently upgraded my 8900 bold from 4.6 to 5.0 OS.

But have some problem with Wi-Fi.

How do i downgrade it to the original 4.6?

Guess he think's he has a bold.. when he really has a javelin.. But his profile says 8800... :|

So anyway. You'll need to wipe your phone with jl_cmder and delete the OS 5.0 files off your machine. Install the 4.6 files and run loader.exe

You do not need to use JLCmder and wipe a device to downgrade the OS on a BlackBerry... overkill and unnecessary.

Do this, simply: How do I downgrade the OS on my BlackBerry? - BlackBerryFAQ
