Htc Flyer

This Guide is designed for complete noobs who are running Honeycomb and want to roll back to Gingerbread. Ideal if you are wanting to s-off - root and flash a custom Rom onto your device.

Step 1 - Find out your what Rom version your HTC Flyer is using.

Here is how to do this.

Download Fastboot and abe tool for Windows here. Linux here. 

Extract the android-win-tools.zip to your desktop in a folder called "adb".

Run a command prompt. Start - Run - Type cmd - Press return. 

Navigate to the desired "adb" folder using the cd command. cd C:\Users\USERNAME\Desktops\adb\

Boot the Flyer into fastboot mode.

Run the following command in Command Prompt fastboot getvar cid

You should something similar to the following:

D:\Users\USERNAME\Desktop\abd\abd>fastboot getvar cid
cid: HTC__001
finished. total time: -0.000s

You now need to find out what Gingerbread Stock Rom you will need to install back onto your HTC Flyer. Please use this guide here.

Once you have found the correct Stock firmware version please download it.

Contact me if you have any problems obtaining the above firmware I have most stored.

Step 2 - Downgrade your Flyer to Gingerbread.

Required downloads

First download the Gingerbread RUU for your device from this thread. Or contact me.

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.

Download my universal misc_version and unzip to obtain the misc_version file.

Download tacoroot

Place both the misc_version and tacoroot.bin files in the same directory as adb

 Procedure

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.

Boot your flyer up to android if it's not already on, with usb debugging enabled and connect it to the PC.

Run the following adb commands

Code:

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

Simultaneously press Volume Up, Volume Down and Power

Reboot your device

Run the following command

Code:

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.

Run the following command:

Code:

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.

Reboot to fastboot:

Code:

adb reboot bootloader

Relock the bootloader:

Code:

fastboot oem lock

Go back to fastboot mode ( lock causes the device to reboot )

Run your RUU ( if on linux or mac, see other similar threads from me on how to RUU on those OSes )

Once the Rom installs *(can take up to 10 minutes). You will now be downgraded to Gingerbread.
