hi, i have a meizu m5,
I'm new on this forum and i've search over internet and also here to solve my problem but i haven't find anything.
Root permissions enabled on the smartphone.
I'd like to change the value of this system setting :"tether_dun_required".
I've found some tutorial to enable tethering without paying (Vodafone carrier) but when i try to change a value with this adb command
"settings put global tether_dun_required 0"
i receive this output
"Can't not modify the settings in prd firmware!"
Can you help me please?
