Downgrading Android OS

[gooseman11211]

Hello I am in need of some help with my HTC One M8. Currently with the 4.4.4 version of Android installed I am unable to change or add APN to my phone this has caused my phone to not be able to fully connect to my carriers network and I am locked to EDGE speeds for my data. I would really appreciate a guide that would help me downgrade my phone back to 4.4.3 where I am able to change those settings.

Why not upgrade to lollipop to see if it is fixed there?

So if you go to your settings, mobile data, GSM/UMTS Options, Access Point names, then press the three dots in the top right do you get a add new APN option

Heyyo,

Yeah, HTC is awesome with their Rom Update Utility setup. Use that to upgrade... just make sure you back up all important data first as it will wipe your phone.

Do note that those ROMs are the latest version, they will not downgrade your phone to 4.4.3. For all versions except Sprint, it will actually upgrade it further to 5.0.1 Lollipop.
