[Glass Q&A] Legobricke:
Ok....

Finally nailed it.... No more GLASS looping....

I took this unit that was experiencing GLASS loop at firmware X12 to X23... What a journey....

To start.... I downloaded the "minimal adb fastboot" and installed....

Then I downloaded the new firmware from google

I dragged the zip folder to my desktop and extracted it....

At this point, I put GLASS in fastboot mode (Hold camera button down then press the power button. Once power light come on, let go of the power button but keep camera pressed. One the light starts to flash (slowly, not fading), you are in fastboot mode).

I then attached the glass via usb cable to computer (I was operating Windows 10).

Open device manager and look for "android devices" and open it. You should see "Android ADB Interface" - Right click on it and select Update Driver Software". Then select Browse my computer for driver software. The select "Let me pick from a list of device drivers on my computer". Look for "Android ADB Interface". Select it and then update it.

Once this is done, got to your icon tray (should be down in the bottom right of your scree) and right click on "Safetly Remove Hardware or Eject Media". It should open a window up. Confirm that glass is there.

Then go to the desktop where you extracted the firmware and open the folder. Once open, Hold shift and right click. This should give you a menu. You are looking for "Open command window here". select it and it should open a command window.

Then follow the instructions listed on the google firmware page.

I didn't follow all the instructions.... The ones I did were enough to fix my boot looping GLASS -

1.) fastboot devices (This should comeback with a serial number. If it doesn't, be sure you have the glass in fastboot mode)

2.) fastboot oem unlock ( I had to do this because the device would fail when I tried flashing to the device. This was the only way I could get it to take the flashing). It will make you type this twice to confirm you wish to unlock.... This will erase all the data (cache and user data) on the device and you have to be patient.... It does take some time... If you think it has hung up (which I did), I just hit a key on my keyboard and then pressed enter.... It then confirmed that the unit had been unlocked.

3.) After I unlocked the unit, I then typed fastboot devices again just to be sure that it was still reading the GLASS.

4.) fastboot flash boot boot.img - This will fail if you don't have the unit unlocked.... The first time I did this, the glass unit went down and I had to start the process again. The second time I did the process, it worked.

5.) fastboot flash system system.img - This did take a few minutes

6.) fastboot flash recovery recovery.img

Once done, I closed the command window and ejected the glass unit from the computer..... I pressed the power button and BOOM! I was back to a working glass...

One key element I must point out.... allot of this process requires allot of patience....

The pages that are linked above will help you through the process.... I took a week of researching.... But it was worth it...

There are risks involved - bricking/etc.... But this is the process that worked for me...

Good luck!
