As the title asks.
Can anyone please explain to me the difference and when is each needed?
Also how are they performed?
When flashing a new stable over a stable firmware, which is needed?
If i rooted does it change the answer?
I’ve looked for a similar thread but did not find.
So sorry in advance if there is already a thread about this, if so i would love for someone to point me to it.
Thanks in advance!
