It is only possible if Bootloaders are unlocked, which most are not.
SAmsung Bootloaders are Fort Knox.
ON the other hand Google nexus phones dont have locked bootloaders.
please note I said MOST, not all. Samsung Bootloaders are all locked. Most Nokia are locked. Nexus are NOT locked one plus one, NOT locked.
Which phone do you have?
The G2, unless it was a developer edition, was sold with a locked bootloader. which didn't stop it from being unlocked and rooted.
The newer the phone, the less likely anything can be done to unlock and root.
Samsung is extremely difficult. Note 3 and 4 are not possible.
I Like my warranties, I don't mess with that stuff.
but the volume included in my Samsung note 8 annoyed me, but a lot could be uninstalled. Including the offending "Flipboard"
Good morning Rip Van Winkle!! Lol.
I Also have a Note 10.1.
both are tablets. The 8" tablet was a "gift" with purchase of the Note 3.
I Had been drooling over the Note series for a year. Still loving the tablets.
