Hello,
   Anyone know how can I downgrade the OS from 5.1.6.0A to 5.1.3.2G. I mistakenly upgraded to china version, but now I want to go back to global version. I tried the following procedure,
1. Copied the update.zip file to root folder of the phone.
2. Switched off the phone. Held the power button + vol up button. Selected the upgrade and clear data option. It tried to find the firmware but didn't update.
3. Error message was selected firmware to too old.

Can anyone suggest me how to proceed further?

Thanks in Advance
