It has been a while since I published the screenshot of gingerbread on TC970. Now you can flash it on your toy. But remember: I am not responsible on any damages it might cause although I have fully test it on my own.

Thanks chinabull for exploring the structure of griffin firmware and fv+ for wonderful tool to packer/unpacker custom firmware!

Procedure:

1) Download the griffin.zip and extract it to your SD card root folder.

2) Copy the update.zip to your SD card somewhere you will find it in recovery.

3) Power on your tablet with Volume down + Power key and wait a while (5 seconds) then release those keys

4) Do a Nandroid backup first!!! (You can get official version back in anytime)

5) Flash the update.zip

Enjoy!!

PS:

A lot of features are not working, like camera, audio etc. But at least WIFI and EGL are working. You can help to fix it.

This version change is big and it is not compatible with the previous Nandroid backup.

1) ODEXed. To save some space and performance improved.

2) Enable NAND userdata partition to save 220MB from MMC( data partition)

3) Haptic fixed for visual key.

4) Native build image from CM, so there is no customized install message shows up and no Google APP and framework included, you need to install Googleapp separately.

Install method:

BACKUP first!

1) In recovery, do factory reset

2) Install cm-7-xxxx-griffin.zip

3) Install update_griffin-core-sign.zip

4) Install gapps-gb-xxxx-signed.zip

5) Reboot.
