The first part is the special T-Mobile or. Telecom software from T-Mobile G2, identical to the HTC Hero, through the following step by step instructions from (debranding).
A description of the Android Website Help I have for this guide somewhat expanded and clarified.
The Backup and Restore program MyBackup from the Android Market should all programs, Data and settings secure. Then, in addition to the full contents should be copied to the SD card via the USB connection on the PC in a directory. First is the debranding of the G2 Touch, so that it becomes the HTC Hero and then the update is done on Android 2.1. The reason is, that of the telecom or. T-Mobile no update on Android 2.1 are!
need for the debranding of the G2 Touch a “Goldcard” be created and then a downgrade is on Android Version 1.5:
- SD card format: Menu → Settings → SD card and SD memory card found → Formatting SD card
- Gold Card program from the Internet to your Windows PC download
- Gold Card program start, unterVista and Win7 with admin rights
- Enable USB Debugging, → Settings → Application Development
- Get in the CID tool click, if not do MMC0, MMC1 test
The Gold Card You can link gene in the Gold Card program, the own mail address and enter CID. After a short time you will receive an e-mail with an attachment.
The USB memory from HTC Hero in the message bar to connect to the Windows PC provide.
The following three steps all carried out in the Gold Card program:
- Refresh in the Gold Card program, and then select the memory of your hero
- Button “Load GoldCard.img” and upload the file from the mail with the program
- Button "Patch MMC press
Now you have a result message from the Gold Card program made: “Is now a Goldcard”. Then the HTC Hero is free of trademark, Software logos and the telecom and behaves like a Hero at the HTC Firmware.
The update to Android 2.1 to take place in two steps, because the very large amount of data. Now it goes to update the firmware on the Android version 2.1:
- In the menu Settings → Change the date and the date to the year 2011 and make the HTC Hero off and on again
- Now is tested after a certain time, HTC software on which the update needs a Hero
- The battery should be charged or be connected to the power supply with the HTC Hero
- Take care, that the WLAN is active, the HTC Hero
- Must now be installed on the PC or the latest HTC Sync software will
- Pull down on the Hero, the message bar and select Sync HTC
- The program on the Windows run RUU
Then perform the firmware update, the little time needed and the HTC Hero and then switches off and automatically restarts. The update for Android version 2.1 is the size of 79,88 MB and has the system update, the point: 3.32.405.1. Here is the patience necessary and if necessary. the necessary questions of the messages to answer and wait.
Subsequently, the data stored on the PC directories to the SD card with the USB connection to copy back to the SD card in the HTC Hero. The restore from the backup of programs and data import again from the SD card into the memory. Subsequently, other necessary adjustments to the individual widgets, Settings, Twitter client browser and the air pressure.
The HTC with Android Hero 2.1 rooten:
As the official HTC firmware is now installed, will take a little, as there is still no official root for the official version Android 2.1 are.
For good order sake, I would like to point out, that the guarantee for the G2 will expire by the Touch hardware Debranding.
Addendum of 08.07.2010: If you have installed the Android App Update Notifier, one is reminded of a whole lot of updates for installed apps, exclusively for use from Android 2.1 available.
Addendum of 09.07.2010: It will be the last update for the HTC HTC loud Hero.
Addendum of 15.10.2010: In the meantime, HTC has an update “over the air” Android to version 2.1-update 1 delivered.

Hello.
When I step in 5 on “Get CDI” click, I get the message “Failed to get CDI”. Is this normal? If not, what am I doing wrong?
Thank you apologize in advance!

Thank you for your precise instructions – it works beautifully. I only had problems with the RUU … the phone was not recognized (Win 7 x64), until I found out, that after each (unsuccessful) Start the RUU, the driver of the Hero needs to be reinstalled. (Also, if the boot loader can not be accessed.) Strange, But ultimately, it runs…

Habs have to read twice. He has only written, that there are none. ^^
Have gone through the whole procedure and I am really glad to have found this guide!!! Something I need to correct but still.
And although the point “Update Firmware”:
2. Now is tested after a certain time, HTC software on which the update needs a Hero <— Has he made, downloaded and restarted, However, aborted with an error.
Only after the RUU, respectively hats with the new version works. Think this is because, that is really missing the branding aufm Android until after the new installation.
Yet again, many thanks!!
