[Desire HD Android Development] :
what I am about to say may be interpreted as somewhat "not so polite"; but this is an attempt to explain something to you guys.

- if you dont know what s-OFF does, you all should rethink whether you need it. I would go as far as to say: If you dont know - you should NOT flash it.

- as you can see, even with the best guides out there, the creators and the rest of us "trainers" must assume you guys have a minimum understanding of android, rooting etc - and furthermore, be somewhat able to read the instructions :)

- The creator of this thread has included easy-to-understand instructions. This is typically NOT the case with all the other things this s-off bootloader lets you do. Usually, all the devs will do is post a link. Sometimes with some generic instructions. Because they DO assume that you know what you are doing. They assume you have adb, know the commands, are capable of flashing images from fastboot, and know how to recover from "****-ups". They want to talk about the power/features they unleash with their efforts, NOT how to get them on your phone.

- I cannot stress this enough. Before you guys flash away S-off bootloaders (most people will agree with me here) - you need to have an understanding of what you are about to do. Not only will you void your warranty (as a matter of fact, you do that also by rooting, but rooting will typically not result in a brick and can be reverted easily), which a flash attempt of a bootloader CAN result in. So you void your warranty, and you flash an engineering bootloader on your device. Whilst this BL gives you a lot of "power", as always, power is nothing without control.

- My advice: If you are new to android, and/or have never ever flashed or rooted a phone (ie. you are pretty fresh), refrain from the bootloader flashing.

- If you dont know what "permissions are", or you dont know what superuser.apk does, how to allow su access, how to adb push or things like this, well...

- If you are unable to read, understand and perform such guides as this one without needing a lot of help, you simply do not need a s-off bootloader. Nor should you have it to be honest.

Again, I am not trying to make you guys feel bad. But you would not trust a driver who just passed his license test in a 70HP car to drive you around in a 600HP car with traction control off would you?! well same goes here. It is great having a 600HP car. But there is a reason for a safety measure such as s-on.

There is great benefit and fun in learning this stuff. Start from the beginning, figure out and master your device, then move to root. play around with it, wait for some easier ways to mod your phone to become available, and play around with those.

Will you "brick" your phone in the process?! certainly, but with safety measures on, all you do is "oversteer" and do a 180. You wont crash into a wall with 280km/h. You wont lose the 50K car (or the 500+ EUR phone) in the process.

You can recover your 600HP car and recover from the "brick". And the great thing is, as with all in life, you learn by doing mistakes. Once you managed all this and you are confident, well then you are ready.

S-off itselve doesnt do "anything". I LETS you do something, lets not forget that. And this, the "letting you do something", that is where you need to the use your skills to be able to use it right.

If you cannot complete the steps that are explained in such a good way as here or in other tuturials - well - you simply are not ready and you should not tamper around with s-off bootloaders.
