[Q] Need to unroot Samsung Galaxy S4 for warranty
Need to unroot Samsung Galaxy S4 Model SGH-I337M Bell Mobility for warranty purposes.
I am a newbie to rooting and a while back I followed the thread linked below and used CF-Auto-Root method to root my phone.
Now I need to unroot it so I can send it in for warranty by May 5th, 1 year warranty will be up then.
I have done some looking online and think that I understand the unroot process is done by finding the stock Bell rom online then using ODIN to flash the phone. Basically the same way that the root was done using Chainfire's method only in reverse. I think using the method I did to root the phone it still has the stock recovery so is unrooting just that simple? Could someone please confirm if this is correct?
Is this all that needs to be done to unroot the phone?
Do I need to uninstall apps that require root?
Should I do a factory reset after?
Do I need to use triangle away after so that Samsung can't tell the phone had been rooted?
Thank you for any help offered, much appreciated.
