[ROOT][UNROOT][CWM RECOVERY][STOCK KERNEL][STOCK RECOVERY] Google ADT-1 Android TV

[npjohnson]

Hello All,

Root
If on stock, uprooted (ever), go to method 1. If not, keep reading.

Now, in the latest Molly CF-AutoRoot, it flashes a modified kernel to gain root that causes OTA updates (i.e. impending 5.0.1) to fail, this was due to the fact that until a couple days ago, the modified kernel was necessary. Chainfire found a way to fix it without modifying the kernel and implemented it in SuperSU 2.37. If you are rooted, used CF-Auto Root, and wish to retain root, but regain the stock kernel for OTA's, simply follow root method 2.

Method 1

To Root from stock LPX13D, Download the following attached files and place them on your desktop (important):
- CWR_MOLLY_LPDX13D.img
- UPDATE-SuperSU-v2.37.zip

1. Install ADB on your system using: http://forum.xda-developers.com/showthread.php?t=2588979
2. Plug in your USB Keyboard to the back of your ADT-1
3. Enter the settings app on your ADT-1, go to "About" ==> "Build Number", and tap multiple times until it says "No need, you are already a developer. Exit this menu and you should now see a "Developer Options" menu, select it and check "Enable USB Debugging" and confirm your choice.
4. Go to Settings ==> Security, and check allow apps from unknown sources, confirm your choice.
5. (On PC) Plug in your ADT-1 and open a PowerShell (or CMD Prompt) and issue the command "Adb devices, and verify that your ADT-1 shows up as "device" and not "offline", if offline, reinstall ADB/Check your USB connection, then run "cd desktop"
6. Now run the command "adb reboot bootloader"
7. Run "Fastboot devices" to verify your ADT-1 is connected.
8. Here you have an option... if you want to be able to unroot and take OTA's, Run "Fastboot boot cwm_molly_recovery_lpx13d.img", as this will just boot CWM once, leaving the stock recovery in place or if you want a permanent custom recovery, run "fastboot flash recovery cwm_molly_recovery_lpx13d.img", but beware, no OTA's without stock recovery!
9. (On the ADT-1) Using your USB keyboard, use the down arrow key to select "install zips"
10. Select "Install Zip from sideload"
11. (On PC) run "adb sideload UPDATE-SuperSU-v2.37.zip"
12. (On ADT-1) Select "**Go Back**"
13. Select "Reboot to system"
14. Select "No" when asked to restore Root, as this's feature does not work yet.
15. Profit!

Method 2

To Root from CF-auto rooted LPX13D and regain stock kernel (This will not restore Build.prop and other system changes!), Download the following attached files and place them on your desktop (important):

- CWR_MOLLY_LPDX13D.img
- UPDATE-SuperSU-v2.37.zip
- stockbootlpx13d.img

1. Install ADB on your system using: http://forum.xda-developers.com/showthread.php?t=2588979
2. Plug in your USB Keyboard to the back of your ADT-1
3. Enter the settings app on your ADT-1, go to "About" ==> "Build Number", and tap multiple times until it says "No need, you are already a developer. Exit this menu and you should now see a "Developer Options" menu, select it and check "Enable USB Debugging" and confirm your choice.
4. Go to Settings ==> Security, and check allow apps from unknown sources, confirm your choice.
5. (On PC) Plug in your ADT-1 and open a PowerShell (or CMD Prompt) and issue the command "Adb devices", and verify that your ADT-1 shows up as "device" and not "offline", if offline, reinstall ADB/Check your USB connection, then run "cd desktop"
6. Now run the command "adb reboot bootloader"
7. Run "Fastboot devices" to verify your ADT-1 is connected
8. Run "fastboot flash boot stockbootlpx13d.img"
9. Here you have an option... if you want to be able to unroot and take OTA's, Run "Fastboot boot cwm_molly_recovery_lpx13d.img", as this will just boot CWM once, leaving the stock recovery in place or if you want a permanent custom recovery, run "fastboot flash recovery cwm_molly_recovery_lpx13d.img", but beware, no OTA's without stock recovery! Then you must run "fastboot reboot recovery"
10. (On the ADT-1) Using your USB keyboard, use the down arrow key to select "install zips"
11. Select "Install Zip from sideload"
12. (On PC) run "adb sideload UPDATE-SuperSU-v2.37.zip"
13. (On ADT-1) Select "**Go Back**"
14. Select "Reboot to system"
15. Select "No" when asked to restore Root, as this's feature doe snot work yet.
16. Profit!

Unroot

Requirements:
- stockbootlpx13d.img
- recovery.img

1. Enter the SuperSU app, and go to Settings ==> Full Uproot, and verify your choice. (Stop here if you didn't use CF-auto root)
2. Plug your ADT-1 into your PC and run the command "cd desktop", then "adb reboot bootloader", then "fastboot flash boot stockbootlpx13d.img"
3. Run "fastboot flash recovery recovery.img"
4. Then "fastboot reboot"
5. Un-Profit!

To take an OTA Update

If you followed this guide correctly, just unroot from within SuperSU as shown in Step 1. Of the unroot section. It will leave you 100% stock. Then take the OTA.

CWM Recovery (cwr_molly_recovery_lpx13d.img): https://www.dropbox.com/s/yqu6lhuvzcz2rsu/recovery.img?dl=0

Thanks for this! Should the file on dropbox be named cwr_molly...? When I go to the download it simply says recovery.img.

good work

This is awesome, thanks for sharing, I'd really like to see TWRP ported as well, they allow OTA installs/mtp, adb sideloads & more, this is a great step in the direction of seeing custom roms

 

[npjohnson]

OP download links updated. My apologies.

 

[npjohnson]

Well, TWRP didn't have mouse/keyboard support last I checked. So I'll work with it. But Philz Touch recovery or cannibal open touch should be both cool and doable.

Edit: TWRP has mouse & keyboard support and is possible, but requires a bit more work than is worth it right now.

CWM also has iffy support for OTA's I am finding, hit or miss, try at your own risk.

CWM also has the ADB sideload ability...... that's how you have to flash the SuperSU mentioned in the OP

 

[jscat1]

I cant seem to get this to work. I tried using just the boot option and it just reboots into the bootloader. I tried the flash as well and recovery never boots. Any chance the problem is that this is for the ADT1 (molly) and not the Nexus Player (Fugu)?

 

[zarthan]

The title of the post indicates ADT-1. You need to make sure any modification you do is appropriate for the device you have. The ADT-1 uses and Android processor/chip set while the Nexus Player uses an Intel processor/chip set.

 

[jscat1]

Is there not a subforum for the adt1?

 

[bunchies]

hmmmm CWM

 

[npjohnson]

Is there not a subforum for the adt1?

No there is not! I know, it sucks, but until that changes, looks like we are setting up shop on the fugu forums. XD

 

[gullatec]

thanks so much for this. the ADT-1 needs more love on xda

twrp

if you guys could work on twrp that would be awesome, I plan on working on a rom with my kernel soon, for now check out my kernel and let me know how it runs in origin dev section

Thanks man. TWRP is actually gonna be more than it is worth. CWM should work just fine, it actually has better support for keyboard.

I'll mess with it. Did you build the kernel with the ADT-1 and x86 architecture in mind?

Haha. Sadly no. I had a partially working tree until gtvhacker posted a fully functional CWM. I gave up after that. You should pry ask him, if he gives you access could you shoot the links over to me? My partially working tree has been the only reason I haven't built CM yet. It fails mid way through compilation.

im working on a new tree. open to anyone to contribute and add things. created a github organization for this purpose
https://github.com/adt1-dev
PS: im new to this and learning on the way.

Edit: are your sources on github?

If you're referring to the builds I released on GTVHacker forums for CWM recovery on the ADT-1, I didn't build the kernel or use any Android TV or ADT-1 source (it wasn't even available when I had started). I just used generic CM Android 4.4, reused the kernel and fstab from the stock ADT-1 recovery, and made a few changes to the default generic BoardConfig.mk.

Any plans on making recovery for nexus player? Just curious

 

[illuminerdi]

Can someone direct me to a stock copy of a (full) build.prop from LRX22G? I think my build.prop is incorrect (long story, let's just say the LRX22G OTA did not go smoothly for me) and I want to just flush it and replace it with a "clean" one?

Thanks

You can just download the factory image and extract it. Here is a little tutorial if you are unsure how to extract.
