[Desire Android Development] pizzabomber:
Please help me clarifying some questions

Hi,

i have some questions and hope you can help me to understand, what i can do and what i can't....

My device is an original/unbranded HTC Desire. I bought it used from Amazon.de (Germany). At the package there is a label which says, that this is an AMOLED Version an with Android 2.1. But when i look at the Software-Information-Menu i can read the following:

Android 2.2

Baseband 32.43.00.32U_5.09.00.20

Kernel 2.6.32.15-gf9c0527 htc-kernel@and18-2 #1

Build 2.09.405.8 CL218634 release-keys

Software 2.09.405.8​

When i enter the Bootloader, the infos are:

BRAVO PVT1 SHIP S-ON

HBOOT-0.92.0001

MICROP-031d

TOUCH PANEL-SYNW0101

RADIO-5.09.00.20​

Now i don't know: did Amazon update the Firmware of the phone or did the preowner apply an OTA-Update? :confused:

And here are my Questions:

1. Now i like to root my device and i read in this thread that OTA-updated devices have issues with routing. Can you please confirm, that rooting with the unrevoked 3.21 method is save for me or not???

2. In the meantime there is a new OTA-update available from HTC (again 2.2 Android, but newer...). Is it save for me to download and install this new OTA-update (i think this is software version 2.10) and

then

root my device?

3. Does unrevoked 3.21 method wipe my device and/or wipe my SD? After this my software should be original Stock HTC-ROM with root added, or did i understand something complete wrong?

4. What about future Updates? OTA is not working on rooted Desire... is there a possibility to apply new HTC updates without wiping the device and without the need to install a complete new custom ROM?? I like to stick with Original-rooted ROMs and be up-to-date... custom ROMs usually interesting me not until i used Stock ROMs for min. one year :)

5. Ok, i'm paranoid :p ... but before doing anything that removes warranty from my new device, i like to have a fast emergency plan for the case i have to send my device back unrooted. Can you please help me to find the correct RUU for my device to restory factory defaults?

here http://xdaforums.com/showthread.php?t=695667 i didn't find a matching File to my current ROM. But here http://shipped-roms.com/shipped/Bravo/ i think "RUU_Bravo_Froyo_HTC_WWE_2.09.405.8_Radio_32.43.00.32U_5.09.00.20_release_140022_signed.exe" could be the right one? Does this unroot my device / return to factory defaults / bring back warranty??? Please confirm this or correct me if i'm wrong...

6. Do i need a goldcard for any of the above steps?

7. One last question: when i like to have App2SD+ (the method with the ext2/3 partition on SD), do i have to install a supported custom ROM for that, or is there a really easy method (like unrevoked 3.21 looks easy for me) to install App2SD+ on my rooted ROM (if so, is there a method without the need to wipe the phone)? Can you point me to a tutorial matching my Stock-ROM-version, when being rooted?

Please help me to clarify all of these questions, because i'm totally blended of all those possibilities, different devices, different issues and new methods in the whole rooting-thing :rolleyes:

Thanks everybody for trying to help me!!! And sorry for the long post and many questions, but this is all affecting my rooting-plans...and i know... i'm a Android-Noob :rolleyes:
