Before you do anything — Make a backup

Don't forget to back up your data. If you have synced the device with a Google account, then the contacts, calendar, Gmail, & select other Google-related data will not be lost and will come back after the next sync. However, you should backup anything you want to keep that is not stored on the SD card:

• SMS/MMS messages,
• Call Log,
• Bookmarks,
• Applications; use Titanium Backup or the Astro File Manager, for example,
• Any application data not on the SD card.

It would also be a good idea to backup everything stored on the SD card in the rare case the SD card must be formatted to resolve any major problems.

MyBackup Root, SMS Backup & Restore, and Call Backup & Restore are all free applications that can assist with backing up your data.

Rooting the HTC Tattoo

1. You will need ADB on the computer to root the HTC Tattoo. Follow the Android SDK guide, to get the ADB shell on the computer.
2. Download m7 & Superuser package:
   • m7: Download

     md5: 0f8c613cc665009b11adcb1b8816b320

   • Superuser package: Download

     md5: 476d49f9895a3cff0d0609240e572c05

3. Unzip both zipfiles and copy the contents to the same folder as adb (the /platform-tools folder within the Android SDK folder).
4. Connect the HTC Tattoo to the computer via USB.
5. On the computer, open terminal and run the following commands:

   adb shell "mkdir /data/local/bin"

   NOTE: If it returns an error, it means that the directory already exists, just proceed on.

   adb push m7 /data/local/bin/

   adb shell

   cd /data/local/bin

   chmod 755 m7

   while ./m7 ; do : ; done

6. A lot of of text will start appear in the terminal. This is normal. After a moment you should see #. Run the following commands:

   export LD_LIBRARY_PATH=/system/lib

   export PATH=/system/bin

   id

7. You should get something similar to this: uid=0(root) gid=1000(shell) groups=1003(graphics),1004(input),1007(log),1011(adb),1015(sdcard_rw),3001(net_bt_admin),3002(net_bt),3003(inet). uid=0(root) is the important bit here; this means the root was successful. We still need to make it permanent & easier to us. Run the following commands:

   exit

   NOTE: This is to exit the adb shell. Do not exit the terminal.

   adb push su /data/local/bin/

   adb shell

   cd /data/local/bin/

   chmod 755 su

   while 'true' ; do ./m7 ; done

   export LD_LIBRARY_PATH=/system/lib

   export PATH=/system/bin

   chown root.root su

   chmod 4755 su

   mount -o rw,remount /dev/block/mtdblock5 /data

   mount -o rw,remount /dev/block/mtdblock3 /system

8. At this point the HTC Tattoo is fully rooted. Continue to the next section.

3. Copy the ClockworkMod Recovery to the root of the SD card (NOT in any folders).
4. Connect the HTC Tattoo to the computer via USB.
5. On the computer, open terminal and run the following commands:
