Downgrade firmware to make Settings.apk and Launcher2.apk working

[GoogleCodeExporter]

Hi,

This is an urgent request.  Please help me!
I got the G glass around Thanksgiving, and download Settings.apk and 
Launcher2.apk from www.glassxe.com.  My project needs to communication through 
Bluetooth data channel.  With these two apks, it works fine.

This week, I connected the G glass to my PC and it started auto upgrade, after 
the upgrade, the above two apks no longer work.  I had to uninstall them.

I am wondering how I can down grade the glass firmware or settings to make the 
above apks work again.  I knew that they are unofficial packages, but we have a 
very important demo to the potential investors, and we really need to make it 
work.  

Please, any help is highly appreciated.

Regards,

Xiaosong.

Hello,

Unfortunately, this is not a use-case we officially support and won't be able 
to easily reproduce. You might find better help on the glassxe.com forum, the 
glass-community forum or the Glass Explorers community.

Also, there might be updated APKs that do work with XE12.

Best,
Alain

Hi Alain:

Thanks for the prompt response.  I understand your concerns.  The real issue is 
that I cannot get to the root acces as described from 
https://developers.google.com/glass/tools-downloads/system

1. $ adb reboot bootloader 
2. $ fastboot oem unlock 
3. $ fastboot flash boot boot.img 
4. $ fastboot reboot $ adb root 

After step one, the glass either cannot boot up, or boot up normally, but not 
in fastboot mode.  Basically, nother shownup if I type "fastboot devices".

I am using a Win 7 machine, with usb cable connects to Google Glass.

Do you know this problem by any chance?

Thanks in advance.
