[Desire HD Q&A, Help & Troubleshooting] vuedesprit:
Finally I got my DHD, the time where everything is rolling out, from perm root, to recovery...

The good thing, I'm very happy with my DHD, the bad thing, I'm not familiar yet with android system.

I revised a lot of android and DHD threads, and I faced many new terminologies that belong to android where I like to have explanation for each.

Please let me understand the following issues the beginner way, allowing me to maybe make a simple guide answers for most new android users coming from winmo.

I-General questions:

1-DHD should be multitouch. Then why games like Gameloft are not multitouch like on ipod or iphone?

2-What are the buttons combinations for the different operations like hard reset & boot loader?

3-I read that android can’t share internet via USB for those with no WIFI at home or office. As I knew it’s due to ad hoc issue so it's impossible to get internet via USB cable from desktop. When I plugged my DHD, I choose internet pass through and I got internet on my DHD, is it a new feature implemented in DHD only, or is it a 2.2 update that will work on other devices?

4-Winmo gives the choice to install applications on either the device or SD card. Android have nothing like this, so when I install applications, where do they go, and is there a workaround to put everything on SD card, or maybe give choice to where to install?

5-My DHD comes with an 8 GB mini SD card where there are some folders and files on it. Are they necessary to run the system, what if I replaced this card with another formatted one, what will happen, or what if I format this card?

II-System info:

1-Baseband version (is it like the radio in winmo?)

2-Kernel version (is it one kernel for the entire device? Does it updates like rom or like radio?) e.g. (kAmMa's OC&GOV&BFS Kernel - Performance and Stability. Is this a rom or just kernel that will update some parts of the rom without losing data on the device?)

3-Build number (is this the firmware?) e.g. (i have 1.32.405.3 CLxxxxxx release-keys, what does release keys means?)

4-Software number (or this is the firmware?)

III-OTA ACE with radio:

1-OTA (is it a rom, does it mean over the air, if yes what does that mean? Can we update OTA with no root?)

2-ACE

On winmo (HD2), I know HSPL will let me unlock ISPL so I can install any custom or cooked rom, languages and applications...

For android, as far as I know there is no one click solution. From what I understand to do everything in android with no restrictions u need to do the followings:

IV-How to root Desire HD install h-boot (S-Off) and Clockwork recovery?

Please identify which one is just a process that we do it once in order to unlock it, which is a boot loader run application and which one is an android application:

1-Root (is it what gives access to the root folders of the system that maybe are hidden by default or encrypted?)

2-Hboot

3-S-off (is it security off? if yes, it is security off for what? installing applications, or read write to some encrypted partitions?)

4-Clockwork (is it something necessary to do in order to install custom rom, no adds, backup and so on, or is it something totally independent and related only to unlock the speed of the CPU where you can leave it intact if you won’t play with the CPU speed?)

5-Recovery (from what I understand it seems that recovery is a system shell command like dos or more like bios for android but named as recovery, what can we do with the recovery other than recovering the device?)

6-Recovery image (is it a rom backed on the form of image and provided by developers, so we can install it directly on the device using only the recovery shell?)

V-More things to know about:

1-What is adb?

2-What is busybox?

2-What is fast boot?

3-What is eMMC write?

4-What is ext2 or ext4 (is it like the partition type of the SD card based on UNIX system? if yes, why should we change or modify this ext)

5-Rom manager (is it a desktop pc application or android device application? is it something like I can put the RUU file of the rom on my SD card and using the rom manager I can install the rom from there, nothing more nothing less?)
