[Q]Kernel Is Not Seandroid Enforcing, Set Warranty Bit. topic

Hi all,

I've been trying to unroot my friends S4 and I keep seeing this warning message. From looking through the forums I'm seeing that if we just re-load a stock image onto the phone this message should go away, but it would seem that every rom I have downloaded is custom.

I have tried multiple stock roms (including the ones from androidrootz and sammobile)

The model is SGH-I337M Canadian phone from Rogers

Any assistance would be great (like maybe where I can find a stock rom image?)

Thanks alot
