[Shield Tablet General] IKOB3AST:
Unofficial nVidia Shield Tablet (Original) Update to Android 6.0

| ROOT INCLUDED | Updated 1/21/16 |​

I take no credit for the development of this update other than this simplified guide. All of the development was from here mostly via the user 'fards' efforts, castrwilliam's found here, and Steel01 found here

THIS IS A MODIFICATION TO THE ORIGINAL SYSTEM PUT ON THE DEVICE BY NVIDIA. BY FOLLOWING THESE STEPS I ASSUME NO RESPONSIBILITY IF YOU BREAK YOUR DEVICE. THESE IMAGES ARE NOT FULLY TESTED. PROCEED AT YOUR OWN RISK KNOWING UNLOCKING THE BOOTLOADER VOIDS YOUR WARRANTY

Installation Steps

Now begins the fun part, you will need to issue the following commands in order:

Step 1: You will need Fastboot drivers and be in a Fastboot permissible state on your Shield Tablet (Power button + Volume Down).

Step 2: Be in the directory you placed the files you downloaded (IE: "cd \users"username"\downloads")

Step 3: You will need to flash the Staging Blob downloaded from above. In a Command Prompt (or corresponding Window) type "fastboot flash staging blob.img"

Step 4: Power down the device and power on the device (it will bootloop).

Step 5: Return to a Fastboot permissible state (the bootloader).

Step 6: Issue the command "Fastboot getvar all" and ensure you see the line "(bootloader) max-download-size: 0x06000000" If you do not see that line, you flashed the blob wrong... so try again.

Step 7: Issue the command "Fastboot format system"

Step 8: Issue the command "Fastboot erase recovery"

Step 9: Issue the command "Fastboot format cache"

Step 10: Issue the command "Fastboot flash boot boot.img (Use your BOOT.IMG name, unless it is actually named 'boot.img'")

Step 11: Issue the command "Fastboot flash recovery twrpXXXXXXXXXXX (Not actually the recovery name, use tab-complete)"

Step 12: Issue the command "Fastboot flash system reducedsystem.img"

Step 13: Reboot.

Step 14: Return to a Fastboot permissible state.

Step 15: Issue the command "Fastboot format userdata"

Step 16: Reboot [MENTION=2827815]terrigan[/MENTION] (happy? :))

Optional Stylus Support:

Known Bugs

●Battery Drain (see fix)

Battery Drain Fix

Thank you to [MENTION=7171813]sockusminimus[/MENTION] for finding this fix. What you need to do is be rooted and open a terminal emulator and issue these commands in order:

• su

• mount -o remount,rw /system

• chmod a-x /system/bin/logd

• Go wipe cache in TWRP

Utilizing this battery drain fix will break system logging.

●A note for post-installation Android M end-users: DO NOT panic when the OS runs poorly. For the first several hours following install and use it will lag. This will subside, the ROM has a settling period. After the settling period, it SHOULD run smooth as stock OG shield 5.1.1
