For Android TV, but inside have an old boot_from_usb.img delete this and use the new from the guide above:
https://goo.gl/2H2thd

But you must be able to do at least this. Is for you, in case in future you want change from an OS to another and also with new firmware versions.

open the windows command and write
simg2img.exe vendor.img vendor.ext4.img

delete the original vendor.img and rename vendor.ext4.img to vendor.img

The same thing for system

There is nothing more simple than this.

I tested with an old 2.5 HD inside an usb adapter and with a Magnum 64GB flash drive

But today will arrive a monster Samsung evo 850 ssd
I want extreme disk speed

On the old 2.5 HD, After the first installation and android apps update at first boot, i installed and played many games without problems. The disk speed was just 60 MB/s read and write

The new Samsung evo ssd should have 540 MB/s 520MB/s read and write

[zulu99]

Well my Samsung Evo 850 arrived

i made some comparisons.

In the attachments you can see the results compared with the internal disk.

My Shield TV that originally have only 16GB, now have 500GB and is faster in every operations. Very very fast. Also more that Shield TV Pro.
The beauty is that i can run the OS from USB, the OS that i want, full Android or Android TV. And i can also make tests and experiments without touch the internal configuration.

This is an extraordinary thing, the fastest Android device in the world, i hope that Nvidia not ruin this dream in the next updates and help us to have forever this wonderful functionality. Please Nvidia help us.

sure, usb 3 enclosure.

I solved also another problem.

Since to have DRM for Netflix you must boot the satv_boot_from_usb_1.1.img from boot and not from recovery,
fastboot boot satv_boot_from_usb_1.1.img

I don't want the hassle to use a PC to change the boot images. How we can do ?

very simple, with Flashify https://play.google.com/store/apps/deta ... r.flashify

copy original and modified boot image inside the backup boot folder of Flashify and after with one click you select one or another.
So you can boot from usb or normal boot without getting up from your comfy sofa.

I have everything NOW

Now Nvidia can also sell the Shield TV at 400 $

Updated on the LXC Containers thread the boot images LXC enabled.
viewtopic.php?f=25&t=1604

The new boot image solve the problem to have DRM and LXC containers at same time
i added also a boot image LXC enabled that can boot from USB


In short now we can have:
Full Android
Android TV
Full Android from USB
Android TV from USB
Full Android with Ubuntu inside an LXC Container
Android TV with Ubuntu inside an LXC Container
Full Android with Ubuntu inside an LXC Container from USB ( to have more space and to try things without touch the internal configuration )
Android TV with Ubuntu inside an LXC Container from USB ( to have more space and to try things without touch the internal configuration )


Don't forget, to change boot image on the fly you can use Flashify app like in this video: https://youtu.be/Bsrqg7EqktU

HI,
I am new on this, and two thing that I do not know hot to!

On the Shield, I can not read my files from a Synology NAS, I do the connection on the Android tv settings, he connects to the NAS but on PLEX it does not recognise it!

The other thing is! I do format a USB3 external SSD as EXt4 but on full android he do not recognise it and what do you mean by "copy original and modified boot image inside the backup boot folder of Flashily"? what folder?

Can you do a step by step? please! (i've done old steps from 1 til 7 step)

Thank you
