Difference between stock and custom rom. topic

I have had had several "custom rom flash addictions" to various android models.

I have not been flashing on my Xperia Z1 since i have always have had a feeling there is a bigger risk of breaking the phone.

How big of a difference does a custom rom for the Xperia Z1 make?

Official Vs Unofficial? Whats the difference? topic

I look through the Dev forum here and I see a host of lollipop builds, some claiming to be official, some claiming to be unofficial, most seem to be derivative of CM12.

So Just what is the difference between an Official ROM and an Unofficial ROM?

Surely the only "Official" CM12 ROM is from https://download.cyanogenmod.org/?device=t0lte (for the n7105)?

[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?
