How to Flash a Nokia BB5 Phone using Infinity Best
The steps below explain how to flash a nokia BB5 phone using infinity best
Install Nokia PC Suite (it would install necessary drivers)
Create a new folder on your desktop and rename it to the model of the phone you are about to flash
eg Nokia 201 with model RM-799 (the folder would be named RM-799)
Copy the firmware files you downloaded into this folder
Extract the content of the infinity box zip file
Right click on InfinityBest.exe and Open
When the Infinity Best windows opens, Click on the flashing tab
At the top left hand corner, Click on Connect > USB
Next, Click on Settings > DataPackage path > Change active dir
Navigate to and select Desktop (this is the location of the folder that contains the firmware files)
Tick the checkbox beside "DeadMode"
Tick the checkbox beside "Set Normal"
Tick the checkbox beside "FactorySet"
Click the dropdown box beneath Select Model > scroll to the particular model you want to flash and click on it
(In my case it's RM-799)
Tick the checkbox beside "Use INI". The files for flashing should automatically load (skip this step if the box is already ticked and the files are loaded)
Click on Flash
Connect the phone using USB and wait for the process to complete
Once successful, You should see Done
You can now disconnect and Power on the phone
Important Notice
Do not interrupt the flashing process as it could result in a dead phone
Always try to search well for the latest firmware before download / flashing. Using a firmware below the current firmware on the phone would result in a partially bricked phone (this is because downgrading isn't allowed)
If this method doesn't work for you, then you can try flashing using Phoenix Service Suite
Only flash firmwares for your exact phone model and RM product code
