Hello everybody,

unfortunately, experience teaches me that a growing span of users expect us to feed them everything with a spoon, and are no longer prepared to deal with the basics of the matter described here on their own - let alone carry out a search with logical parameters on the WWW. That's why I've decided to reduce the guides to just what's available in the first 7 posts of this very thread – or found by a thorough thread search. New users, and especially inexperienced users, should start to learn again, to know how to deal with the basics in detail. If you are not willing to do so, no additional assistance will be able to help you out of any difficult situation.

For those of you expecting to be spoon feed, I'll make myself quite clear: these people should keep their hands off their devices and learn to live without modifications. and consequently stay on a full stock device.

Experienced users should not let themselves be lulled by the comfort of such a spreadsheet, and corresponding guides threads, as well and instead always remember themselfs to think more and more actively about the topic of modding yet again. I personally noticed this as well: looking back I have just understood all the changes from the HTC 10 to the HTC U11 - such as the changes and additional risks due to temp S-OFF. But with the HTC U12+, and Treble A/P partition schemes, there are yet again completely new and drastic changes - which I too not yet fully understand. It is always important to stay fit, and be willing and eager to learn new things and new ways to work with such changes, in order to be able to continue modifying devices - as well as to return them to their original condition. That's exactly what I'm doing now, because I'm currently intensely dealing with the HTC U12+ to understand everything, to properly modify it, and to soon know what I have to leave untouched, if I don't want to risk a brick. And I can just put you on the heart to do the very same.

This thread still has - as previously for the U11 - the aim to provide you with one single thread to find what you seek and where every user can participate by sharing files and/or links, as well as new learned knowledge. So this isn't a guides thread from the OP, whom I am, to you, but also from you to me, and you toothed users. So let's think new of how such a guides thread works together!

Make a backup before you start modifying your device!

Here'll be a list of all variants as they come up:

I cannot accept any liability and/or responsibility for these firmware packs. I am not able to go through the process of testing each pack, hence community members are called to test these on their own.​
