So I'm having a problem. Nothing I can do can get my phone to receive OS updates and I cannot upgrade past 4.4.2. I think the problem is that I left Koodo a few months ago due to moving and needing to save some money on my cell plan, so I went to WIND.
The D852 natively cannot use WIND's frequencies, so I had to flash a new ROM on it.
Now that I'm back with Koodo, I reformatted and expected it to let me get updates again, but that isn't the case. Nothing I can do will upgrade my phone to 5.0.1 or higher, or anything...
So I assume I need to put a stock ROM back on it.
Any suggestions on how to do that? I need At least Lollipop for an app I need for work.
