[Hero, G2 Touch General] btdag:
This is aimed at new "rooters". The process is incredibly easy.

I also take no responsibility if you mess up somehow, and this is for GSM Hero's NOT Sprint Hero CDMA users.

In order to create this guide I downgraded my phone to RUU Orange UK 2.73.61.66 (i.e. unrooted) then updated to the pre-2.1 release from Orange and then updated to the final 2.1 release from Orange. I then used Universal Androot to gain root access and from there install a custom recovery.

I have now also included a link to z4root as an alternative.

Here is a link to my backup guide but please be aware that most of it requires root access.

Prelude:

Install HTC Sync from here

Download Universal Androot

Download z4root

Download Root Checker - only if you need to

Download AmonRA Recovery v1.7.0.1.img - easier if you rename this "recovery.img" when it is on your sdcard

Place both downloaded files on your SD Card

Root & Recovery

1. Download and install Astro File Manager from the Market (or use any other file management program of your choice)

2. Open Astro and find and install Universal Androot (or if that doesn't work try z4root) from your sdcard:

Select UniversalAndroot.apk > Open App Manager > Install > Settings> [tick] Unknown Sources > OK > Back > Select UniversalAndroot.apk > Open App Manager > Install > Install > Open

3. In the app and choose the correct version from the dropdown box:

Superuser for Android 2.0~2.2 - if you have updated your phone recently

Superuser for Android 1.5~1.6 - if you have refused updates recently or your country/provider hasn't released one yet

Then choose: "Root :-)"

Wait until it says "Woot ! Your device is rooted !" and exit the program.

4. Download and install Android Terminal Emulator from the Market (use Better Terminal instead if this one doesn't work)

5. Run "Terminal Emulator". Type (press and hold menu to get the keyboard up) in the following:

su (press enter and wait for the "Super User Request Prompt". Choose "Allow" and make sure its ticked to Allow every time.)

flash_image recovery /sdcard/recovery.img (press enter - make sure this is typed exactly as seen)

N.B. If you have issues here, see * notes below for more assistance

6. Turn off your phone and press Home + Power to start it up again. This should boot into recovery mode.

Install Your Custom Rom

Note: This part of the guide can be repeated with as many different rom's as you like. You do not have to repeat the previous section once you have a recovery image installed.

1. Download a Custom ROM from here to your computer.

2. Make sure your phone is in recovery mode (Home + Power)

Plug your phone into your computer and select "USB-MS toggle" in recovery

Place the Custom ROM on your SD card in the main directory and press Home when it has finished copying over

3. Select Backup/Restore > Nand backup > confirm with Home > Wait

(or Nand + Ext if you have A2SD setup)

4. Press back then select Wipe from the main menu, then select:

Wipe data/factory reset > Home

Wipe cache > Home

Wipe Dalvik-cache > Home

Wipe SD:ext partition > Home

Press back button

Select Flash Zip from SD Card

Select the file

Press Home to confirm

Note: Ignore any "errors", they are normal and usually mean you're not using that feature.

5. Once it is done, select Reboot and you will boot into the new Custom ROM.

Updating your Radio

Note: The radio deals with your signal levels and connectivity.

1. Download the latest radio from the following page

N.B. Radio's are not region specific! Just get the latest

2. Mount your SD Card so your computer can read it and place the downloaded file in the main directory

3. Turn off your phone and boot into the recovery screen (holding Home + Power)

4. Choose:

Flash Zip from SD Card

Pick the radio.zip file and press Home to confirm

Wait

Your phone will reboot a couple of times but when you're back on the Recovery Screen just press reboot system now and it will complete the install and put you back into your custom rom.

DO NOT PULL THE BATTERY OUT, THIS WILL BRICK YOUR HANDSET.

5. When this process has completed reboot the phone and you should have the new radio. This can be checked in Settings > About Phone

*Useful Information!!

** Missing flash_image - confirmed to work by another user, please inform if different

*** solution 3

Setup Apps2SD

ONLY RECOMMENDED ON CLASS 4+ SD CARDS. Don't bother if you don't know what this is :). GIYF.

Do this process after doing everything else! So make sure you have a working custom rom installed which supports Apps2SD. This is designed for VillainROM which doesn't use a swap, if your ROM does support swap ask for a recommended amount. Also note that the ext2 partition will be unreadable from windows or through android os.

1. Backup your SD card to your computer (very important as this process will wipe all the data on it)

2. Restart your phone into recovery mode (Home + Power)

3. Select:

Partition sdcard

Partition SD

Press Home

Swap-size = 0 MB

Ext2-size = 512 MB (recommended)

FAT32-size = Remainder

Press Home

4. Once complete Reboot system now and wait! This can take 20 minutes or so to complete, so just keep waiting!

DO NOT USE EXT3 or EXT4 partitions. They will just wear out your sd card quicker. They are designed for large files systems (i.e. 50GB+) with full operating systems running on them! The only benefit they bring is indexing (which on a 512MB partition is worthless). (Optional - before reboot) - Under partition sdcard you can convert the ext2 partition to ext3 - "SD:ext2 to ext3" - however this isn't recommended as it will wear out your sd card quicker. There is also often support for ext4 so you can do "SD:ext3 to ext4" after the first one too. Though again this will typically just wear out your SD faster without providing any speed benefits. See note above.

[B]OLD PROCESS BACKED UP JUST IN CASE. PLEASE DO NOT FOLLOW THIS SECTION OF THE GUIDE![/B]

Largely based upon the Unlockr guides, so thank you Unlockr!

Please do NOT be mislead. This is NOT a quick process, though the time has been reduced significantly if you don't need the goldcard method.
There is no "one-click" version or "quick-install".

You should set aside at least an hour for this process and preferably read through the process once before actually attempting it.

[B]Please make a quick post with your experiences, including your brand of phone and location.
Please check the FaQ first before asking questions :)[/B]

[COLOR=Navy][SIZE=3][U]III. Updating your Radio[/U][/SIZE]

[B]N.B. People have been reporting problems with this part of the guide, try it at your own risk. It is not required to be on the latest radio when using a Custom ROM, however it is usually recommended! The radio deals with your signal levels, I found it to increase my signal from a maximum of 2 bars to full. It is likely to help if you travel, but if you are happy with your signal and tend to stay in the same place it may not be worth it.

Be aware that if this doesn't work it can potentially brick you phone... though I've had no reports of that so far. Just people finding it doing different things after it flashes.[/B]

1. Download the latest radio from the following site:
At time of writing that is: [URL="http://www.villainrom.co.uk/radio/Radio_Signed_HERO_63.18.55.06PU_6.35.15.14.zip"]63.18.55.06PU_6.35.15.14[/URL]
[B]N.B. Radio's are not region specific![/B]

2. Mount your SD Card so your computer can read it and place the downloaded file in the main directory

3. Turn off your phone and boot into the recovery screen (holding Home + Power)

4. Choose:
Flash Zip from SD Card
Click Confirm
Reboot system now when prompted

N.B. This can take anywhere between 1 - 10 minutes or maybe even longer in some cases. Do not touch your phone until you either: get back to the recovery screen or your custom rom loads and you see the unlock screen.

DO NOT PULL THE BATTERY OUT, THIS WILL BRICK YOUR HANDSET.

5. When this process has completed reboot the phone and you should have the new radio. This can be checked in Settings > About Phone > Software Information > Baseband Version[/COLOR]

[COLOR=DarkOliveGreen][U][SIZE=3]Check A2SD[/SIZE][/U]

Please assume it is automatically working unless you can load applications without your SD card inserted. However, here is the process for those who are pedantic about these things. Many thanks to VillainROM Wiki for this process.

1. Download check.zip from the bottom of this guide.

2. Extract check.sh

3. Download GScript Lite from the market

4. Place check.sh on your SD card in a folder named gscript

5. Open GScript and press:
Menu
Add Script
Uncheck "needs su"
Load File
Select check.su
Save

6. Then click check from the main screen and you will get a readout of whether it is enabled or not.[/COLOR]

[COLOR=DarkSlateBlue][SIZE=3][U][B]"GoldCard" Test Procedure[/B][/U][/SIZE]

Please comment on whether this procedure works, it is untested. Thanks to [URL="http://www.villainrom.co.uk/viewtopic.php?f=46&t=1735"]ante0's guide[/URL] for some details used.

[SIZE=3][U]I. Setting up drivers etc[/U][/SIZE]

1. Download the latest HTC Sync from [URL="http://www.htc.com/www/SupportViewNews.aspx?dl_id=933&news_id=631"]here[/URL] and the latest SDK from [URL="http://developer.android.com/sdk/index.html"]here[/URL]

2. Install HTC Sync & extract the Android SDK .zip file to C:\ (may help to re-name the folder to a shorter name, in this tutorial it will be C:\android\ )

3. Click on your Windows Start menu and right click on "Computer" > Properties > Advanced System Settings > Environment Variables

Find "Path" under "System Variables" and edit it. Add the following to the end of the text:
;C:\android\tools

4. Restart your computer.
On your phone, click Settings > Applications > Development and make sure USB Debugging is on.

When back at your desktop plug then phone in and wait for it to install the correct drivers, this should be done automatically on the latest version of HTC Sync and adb should be enabled.

5. Type the following into the command prompt window (Start > Search > "cmd") and enter the following and press enter:

adb devices

You should see a serial number pop up and look like:
000000000000 device
It’s the serial number of your phone. This means the drivers are working in normal boot mode. Next we need to check them in fastboot mode (thanks to janhol for helping with this next part)

6. Turn off your phone and load into fastboot by holding the Back button and pressing Power with the hero plugged into the computer

7. "Start" > Right Click "Computer" > "Manage" > "Device Manager"

8. Check that the "ADB Interface" reads "My Hero", not "Android bootloader drivers" or anything else.

If it does then:
Right click "Android bootloader drivers" > "Update Driver Software" > "Browse my computer..." > "Let me pick from..." > "Have Disk..." > "Browse" > "C:\Program Files (x86)\HTC\HTC Driver\Driver Files\Win7_x64" > "androidusb.inf"

Once selected click "OK".

"My HTC" should show in the list of "compatible hardware" now, so select that and click "Next" to install the driver. Switch off the phone (may have to pull the battery).

[SIZE=3][U]II. Create a “GoldCard” from a MicroSD Card[/U][/SIZE]

(Please keep in mind that some memory cards don’t work for this process)

1. Put the memory card you want to use for the GoldCard into your phone, make sure all the data is backed up before proceeding as it will be formatted.

2. With the memory card in your phone, and not connected to the PC, click on:
Settings > SD and Phone storage > Unmount SD Card

Once it unmounts, click Format SD Card.

3. On your phone, click:

Settings > Applications > Development and make sure USB Debugging is on.

4. Return to the Command Prompt from earlier after re-plugging in your Hero. Then type the following with hitting enter at the end of each line:

adb shell
cat /sys/class/mmc_host/mmc1/mmc1:*/cid

5. A code will display, write the code down into a notepad document or similar (MAKE SURE TO WRITE IT DOWN EXACTLY!)

6. Go to this site: [URL]http://hexrev.soaa.me/[/URL] then put in your code you just wrote down into the text box and click submit. It will generate the code reversed and replace the first two digits with zeros automatically. Copy this.

7. Then go to [URL]http://psas.revskills.de/?q=goldcard[/URL] and Paste your CID into the box and fill in the other details. You'll be e-mailed the goldcard. Save the goldcard image to disk.

8. Now go to [URL]http://download.cnet.com/HxD-Hex-Editor/3000-2352-10891068.html?part=dl-HxDHexEdi&subj=uo&tag=button[/URL] to download the HxD Hex Editor. Install it to your computer.

9. Mount your SD card on your phone so that it shows up on your computer as "Removable Disk" - Pull down the notification bar on the phone and select Mount CD Card.

10. Open the Hex Editor (Run as Administrator if you're in Vista or Windows 7) and click on the Extra menu > Open Disk. Under "Physical Disk" select "Removable Disk". Make sure to UNcheck “Open as ReadOnly”. Click OK.

11. Go to the Extra menu again and click Open Disk Image. Open up the goldcard.img that you saved from your email. Press OK when prompted for Sector Size 512 (Hard Disks/Floppy Disks). You should now have two tabs, one is the SD card (Removable Disk) and the other is the goldcard.img.

12. Click on the Goldcard.img tab and press Ctrl + A (select all) Then Ctrl + C (copy).

13. Click on the Removable Disk tab (Your SD Card) and select the complete lines from 00000000 to 00000170 then press Ctrl + V (paste).

14. Click on File then click Save.

15. Close the Hex Editor.

16. Reboot the phone.

Try to open the memory card on the computer (i.e. mount the drive), if it lets you, you are all set. If it asks/tells you to reformat the card, then try steps 13 – 19 again. If it gives you the same error again, then try a different memory card. You can confirm that it has worked by opening the Removable Disk in the hex editor again and making sure the code you pasted in has stayed but this shouldn't be necessary.

[SIZE=3][U]III. Downgrade the Hero using the Goldcard[/U][/SIZE]

1. With your phone plugged in, pull down the notification bar on the phone and select HTC Sync. Make sure it connects to HTC Sync on the computer (not sure if this is necessary anymore).

2. Download this generic HTC Hero RUU

Hero RUU -
[URL="http://x7.to/6jexri"]2.73.405.5[/URL]
[URL="ftp://xda:xda@ftp.xda-developers.com/Hero/Official-ROMs/RUU_Hero_HTC_WWE_2.73.405.5_WWE_release_signed_NoDriver.exe"]2.73.405.5[/URL] (alternative)

3. Double click the RUU exe you downloaded while the phone is plugged in with the GoldCard in it and follow the on screen procedure. This will install the old generic Hero rom on your phone, this is to allow you to install a recovery image. Reboot and fill in as few details as possible as these will be overwritten soon.

4. Now you have finished this procedure start from the beginning again.[/COLOR]

[SIZE=3][U]I. Setting up the SDK[/U][/SIZE]

1. Download the Latest Android SDK from Google

Android SDK - [URL]http://developer.android.com/sdk/index.html[/URL]
(currently - android-sdk_r06-windows.zip) but get the latest

2. Extract the Android SDK .Zip file to C:\ (may help to re-name the folder to a shorter name, in this tutorial it will be C:\android\ )

3. Run SDK Setup.exe

4. Click "Settings" and check the "Force [URL]https://.[/URL].. sources ..." option

5. Click "Available Packages" and download the "USB Driver Package"

6. On your phone, click Settings > Applications > Development and make sure USB Debugging is on.

7. Plug your phone into your computer via USB cable.

8. Go into device manager: Start --> Search for "device manager"

9. Here we are checking the driver which is installed for your Hero, you may see either of the following scenarios:

Other Devices > ADB
or
Android Phone > My HTC

Either way you should do the following:
Right Click > Update Driver > Browse > C:\android\usb_driver > Next and it should install "Android Composite ADB Interface"

10. Type the following into the command prompt window (Start > Search > "cmd") and enter the following hitting enter at the end of every line:

cd c:\android\tools\
adb devices

You should see a serial number pop up, it’s the serial number of your phone. This means you are all set.

If you do NOT see a serial number, then we need to reinstall the drivers.....
