Hi Everyone

I upgrade my Bold 9700 to OS6 and i have many problems. I want to restore to OS5. How can I do.

Thanks

The same way you upgraded to OS 6.

Wipe with Jl_cmdr (see the FAQ) and reload OS 5 (see the yellow sticky at the top of the 9700 section for the OS and instructions).

1) Download BBSAK 1.9


2) Run BBSAK then click on WIPE DEVICE, when asked to enter a password, leave it blank incase you don't have a password on your device.


3) Wait for a few seconds till you get the confirmation that it was done.


4) Now your device has no operating system and you should see a white screen on the BB


5) Download OS 5.0.0.714 (or any other OS 5 version of your choice, however this one is highly recommended.) ENSURE YOU HAVE UNINSTALLED ANY PREVIOUS OS FROM THE CONTROL PANEL FIRST

6) Install the *.exe file you just downloaded.


7) Navigate to Computer >>> C: >>> Program Files >>> Common Files >>> Research in Motion >>> Apploader


8) Delete the file named vendor.xml


9) Connect your BlackBerry through the USB port


10) Run loader.exe


11) Follow the on-screen instructions and enjoy. (Incase you were given 2 choices whether to leave the applications intact or to downgrade them to the original versions, choose the 2nd option which is to downgrade them, this will ensure you have a completely fresh installation)

Highly recommended by who? If it works perfectly for you it may not be for another user because of so many variables on what we have on our phones. There are later releases of OS5 which I'm sure some users would highly recommend.
