[Q] what's the difference between carriers versions of the same Lollipop? topic






I've got an unlocked gsm h8 that I'm using on the german o2 network. When I bought the phone, I thought that "unlocked" is the equivalent of "unbranded". However, after the Lollipop update I noticed that I got the T-Mobile version of the OTA, 4.19.111.2. Indeed, the CID of the phone is T-MOB101.

There is no obvious bloat on the phone, unless you count fm radio. But perhaps I just don't know what is there from the Telekom and what's from HTC. Moreover, other carriers, for example O2 seem to have the "higher" ROM version numbers, 4.20.xxx.x. What is the difference betwern them? Is there any point on spending time and effort to switch the CID and convert from T-Mobile to O2 or any other version? Is the "truly unbranded" version 4.16.xxx.x any different? They all seem to be Android 5.0.1, but then what do those numbers in ROM versions stand for?
