Hi! I edited my phone's hotspot settings using "settings put global tether_dun_required 0" on the adb terminal to bypass the tether cap my carrier set on the phone, after that I wanted to change the APN settings to add the ",dun" thing, but it was blocked. How can I edit this without root? or do I really need to edit the APN settings for the dun=0 thing to work? Do i need root for the "settings put global tether_dun_required 0" thing to work? How do I know if the adb thing worked? The tethering is unblocked, I just want to bypass the tether gb cap.
