How to HTC ROM Update Utility RUU variant explanation

HTC device owners might be a little confused as to understand the current numbering method used to mark the HTC software update them. Here you can find a brief explanation of this.

we all know that HTC sells their devices throughout the world. Each operator and regions in the world have some "local settings" or less different. By "local arrangements" mean such things as: the emergency call number, language, time zone settings, network settings, the operator brand, GPS settings and much more. Therefore each of the software for the same device to be even different.

Every HTC update has the following numbering structure:

a.bb.ccc.d




a - the first number of the software. Normally it doesnt increase very often, but when it does, it usually means newer Android version.

bb - this number is also a software number. Increasing bb number means some more or less major update based on the same Android version, but sometimes it might even bring newer version of the HTC Sense.
ccc (also cc or cccc) - this is the number of the region/carrier. It has nothing to do with the software itself being newer or older. More details below.
d (sometimes dd) - the third part of the software version (the fourth one in the RUU name). Usually indicates some minor update with some hot fixes.



Example: 3.20.401.3


So basically, when you are interested in the software version, you should look at a.bb.d (3.20.ccc.3) because ccc (401) means only the region/carrier variant of the software.
Here is the list I was able to gather of possible RUU variants:

The list is quite long, and Im sure there are still some some missing. If you know more variants, please let me know in the comments section.

The 401 and the 707 devices are usually the first ones that HTC prepare updates for. Carrier branded software is usually months after the WWE updates.

Finally, keep in mind that each software version is connected with the CID (Carrier ID) and MID (Model ID) of your device. That means you cant use whichever version you want, unless you have S-OFF on your device. Each ROM Update Utility.exe package will check your device details (bootloader version, MID and CID) before starting the update process.
