This procedure applies to both flyers and view

Required downloads

1. First download the Gingerbread RUU for your device from this thread.
2. If you don't have adb and fastboot on your PC
   • Get fastboot and adb tool for windows here
   • Get Fastboot and adb for linux here
   • I don't have a simple bundde for Mac, would welcome a link if anyone has one.
3. Download my universal misc_version and unzip to obtain the misc_version file.
4. Download tacoroot
5. Place both the misc_version and tacoroot.bin files in the same directory as adb

Procedure

1. Check the version number for your gingerbread RUU
   In my example I am using this RUU: RUU_Flyer_HTC_WWE_2.00.405.3_R_Radio_20.3501.30.08 9BU_3809.05.04.10_M_release_194964_signed.exe
   The version is the part highlighted in red.
2. Boot your flyer up to android if it's not already on, with usb debugging enabled and connect it to the PC.
3. Run the following adb commands
   

   adb push tacoroot.bin /data/local/
   adb push misc_version /data/local/
   adb shell chmod 755 /data/local/tacoroot.bin
   adb shell chmod 755 /data/local/misc_version
   adb shell /data/local/tacoroot.bin --setup

   At this point your device will reboot to recovery
4. Simultaneously press Volume Up, Volume Down and Power
5. Reboot your device
6. Run the following command
   

    adb shell /data/local/tacoroot.bin --root

   Your device will reboot, do not worry if it does not boot fully, it doesn't matter for this procedure, and it is a side effect of this root exploit.
7. Run the following command:
   

    adb shell /data/local/misc_version -s 2.00.405.3

   Note that the number in RED is the version number retrieved in step 1.
8. Reboot to fastboot:

   adb reboot bootloader

9. Relock the bootloader:

   fastboot oem lock

10. Go back to fastboot mode ( lock causes the device to reboot )
11. Run your RUU ( if on linux or mac, see other similar threads from me on how to RUU on those OSes )

Special Thanks
jcase for the tacoroot.
