Ah ok, i thought that 1.8 was a system format then complete reinstall of a whole new android image, i did not realize that 1.8 would be installing ON TOP of 1.3 as your post suggest........thats new info to me, assuming ive guessed that correctly........so this final image wont be debloated like i originally assumed, it will have certain android tv gapp apps installed......edit: such as playstore and im assuming play services (Not ideal , wanted this device to be the first without google dependancy, oh well, beggers cant be choosers for now)
[Shield Android TV Android Development] tailslol:
no,it it will erase uneeded stuffs from android tv.in fact it does not have gapps and stuff like that.
[Shield Android TV Android Development] banderos101:
thanks for clearing that up man, thats exactly what i wanted to hear.......this rom sounds better and better everyday

Only wish i knew for certain whether its safe for me, as a 2.1 firmware user, to unlock bootloader/downgrade, root/twrp/and install, considering zulu has made mention, if i understood correctly, either 2.0 or 2.1 has made the boot loader unstable or to that affect..............ill have to wait for someone whose braver then me to risk their recent purchase
[Shield Android TV Android Development] tailslol:
the twrp part is unstable so i dont know what to say here...

try to root at your own risk.

or wait the all in one version and remove gapps or ask zulu to release 3 versions (regular,rooted and all in one)
[Shield Android TV Android Development] banderos101:
Yeah, im gonna wait a little while longer, dont wanna rush into anything just yet, no matter how much i wanna test out this rom/root/and twrp.......

And others, i.e.

-tasker

-xposed

-xprivacy

-afwall

-oandbackup

-etc etc

Edit

Correct order

Twrp/backup/flash rom/root/test

So yeah, waiting game

Edit 2

Even better correct order

downgrade to 1.3/unlock bootloader/Twrp/backup/flash rom/root/test

Update

Heres an update just in case anyone was/is having the same problems I had. So the rom installed great after downgrading to 1.3 and I installed the Gapps arm64 5.1 mini and it seems to be working great. Any cons to using the gapps instead of the capps? also I did see someone up there asking for cast support....so that is a no go? are there any other third party apps that can be installed to act as a "server" type thing?
[Shield Android TV Android Development] tailslol:
Don't worry just downgrade first and follow the step by step of the first post and it should be ok.
[Shield Android TV Android Development] duanim:
Banderos said what version anyone downgrade,so right now I think I did it wrong I did downgrade to 2.0 and think the best version and the right one is 1.3,the 1.4 was working great for me
[Shield Android TV Android Development] Idan73:
October 17 update to google cast started working for me as well, unlike previous one, but it is prone to crashing every so often.

Sometimes it restarts itself so I can continue, sometimes only reboot makes it visible as cast option.

Downgrading to base version is impossible for me. It just never gets seen by apps, so had to go back to Oct 17 version.

Note 5 ?
[Shield Android TV Android Development] Grippen50:
hello all, I'm relatively new in the forum. First I would like to thank Zulu99 for this awesome mod and to tailslol for answering some of my questions via PM. I do not own an Nvidia Shield yet, I ordered mine this week but I will get it only at the end of November when I go to US. I guess I will only play with it in December. Hopefully zulu99 can get us an all-in-on package until then in order to avoid all these bricking risks.

I would also like to agree with zulu99 regarding nvidia and their choices. Why were we given such a tremendous HW solution and we are bottleneck with Android TV? At this pace we will have 50% of the apps we want when the HW become outdated. Full Android should have been the solution and if it wasn't we should be given this option now. As zulu99 mentioned this should be something very easy for Nvidia so why not do it? Once I get my Shield I will write a proper email to Nvidia requesting this and asking them to FW my email to the product manager of the ShieldTV.

That's all for now, I guess I will have something to share when I have mine in hands.
[Shield Android TV Android Development] banderos101:
Ok ive been reading up on this, and ive come to an issue, this page

http://nv-tegra.nvidia.com/gitweb/?...ob_plain;f=README_SHIELD;hb=rel-22r18-partner

which says i need to unlock the bootloader before i can continue to do my downgrade from 2.1 to 1.3.........but ive been getting the impression from zulu that they've messed up the bootloader in the latest stock rom versions which bricked his shield, have i misunderstood that? Is it safe to unlock bootloader on 2.1? Does someone know the specifics of how to avoid the brick?(assuming im right in my assumption)

Sorry for so many questions, i just wanna be extra carefull you know, and get a good understanding before proceeding............
[Shield Android TV Android Development] tailslol:
From what I understood the problem was related to twrp.

But any flashing has risks you have to take care,and this with any devices.

Nvidia tools for downgrading should be safe.
[Shield Android TV Android Development] banderos101:
Ok cool, many thanks........although i hope more details about the twrp issue comes out, specifically what to avoid doing, as i'd like to install twrp and make a backup before flashing this rom, rooting, and then testing
[Shield Android TV Android Development] banderos101:
Okay, so ive unlocked the bootloader while on 2.1, i followed the instructions at the bottom of this link

http://nv-tegra.nvidia.com/gitweb/?...ob_plain;f=README_SHIELD;hb=rel-22r18-partner

to downgrade to 1.3, no errors came up, seems like everything flashed fine, it rebooted into android afterwards, no issues, at least no obvious issues like bootloops.

The about page says SW VERSION 1.3, so looks like it downgraded fine, but doing a quick check on things, ive found that i too now have green screen on youtube videos..........

I got the impression that the green screen only occurred if you flashed the FULL ANDROID version (ive not got to that stage yet) ontop of stock firmware that is above 1.3

Have i missed something here, or is this something new

Im really sorry for being such a nuissance
[Shield Android TV Android Development] tailslol:
ok dit you use the flash all bat in the nvidia package and are you flashing on windows or linux?
[Shield Android TV Android Development] banderos101:
I flashed them individually, i did not realise i could have used a bat file, and im on windows........do you happen to know the command to initiate the bat file?

Ive also just tried flashing twrp, and im getting a dead android with red triangle when i adb fastboot into recovery.....but thats another issue......one thing at a time

Edit

Following this guide

http://androiding.how/how-to-root-nvidia-shield-tv-and-install-twrp-recovery/

If you do happen to know that bat command, i think ill just start over, if not, ill try and google it

Edit

Never mind about the bat file, i didnt realise you could simply click on it

Edit 3

After using the bat file to reflash 1.3, i no longer have the green video issue.......thanks to tailslol, your the man
[Shield Android TV Android Development] zulu99:
HABEMUS PAPAM​

Vesion 2.1 in first post.

Based on last 2.1 firmware

Gapps and Root inside the system image

All functionalities of previous firmwares

Xposed tested OK

You can install from fastboot menu:

fastboot flash system system.img

fastboot -w

fasboot reboot

_______________TO HAVE ALL

p.s.

The real reason of the latest updates made by Nvidia was disable all DRM apps from custom firmwares.

Everything was changed about widevine stuff, but i ported this from last stock firmware.

The vendor folder is quite all based on last stock 2.1

There are also the last libEGL_tegra for games

Let me know if you can't do something

TO HAVE CHROMECAST WORKING UPDATE THE APK FROM HERE:

https://www.apkmirror.com/apk/googl...receiver-1-16-45911-arm-android-apk-download/
[Shield Android TV Android Development] Grippen50:
Great can't wait to apply this to mine :) once again thanks for your effort on this.
[Shield Android TV Android Development] banderos101:
Wow, that is great news man........cant believe how quick you did it

So did you managed to unbrick your shield or rma come through, and not to seem like some sort of ungratefull person, but any chance you might be releasing a non gapps version in the future

Congrats on the release, cant wait to try once i get to that stage
[Shield Android TV Android Development] zulu99:
With Root you can remove all that you want. With Root you are the REAL owner of your device. ;)

Rma, and i also bought another Shield TV.

For now i suggest to use the stock recovery. For this reason i made a firmware with all inside installable with fastboot.
[Shield Android TV Android Development] tailslol:
have you fixed the video acceleration?

so,is it 2.1 compatible or you need to be 1.3 still?
[Shield Android TV Android Development] zulu99:
Is based on last stock 2.1. I installed it one million times over 2.1 firmware.

The procedure now is super sure because you inatall only the system.img with fastboot to have everything without use custom recovery.

About videos, i played all kinda of videos with Kodi and MxPlayer. H264 and H265 are hardware accelerated like in the previous versions.

For others formats i not tested all but is not important because you can play very well in all conditions.

I not tested many games, let me know.
[Shield Android TV Android Development] KING SKILLZ:
Was using the rom initially with android tv version 2.0 as i updated upon setting up this device before i discovered this rom, i had already rooted this device before applying this rom also, was having issues with 2.0 and this rom with nvidia sheild hub where as games were freezing and not starting at all. So i downgraded to 1.3 and re-applyed this rom, and while it cleared up most of my sheild hub issues, i am now getting a green screen(no video) in the plex app(market place version) and in kodi. Is anyone else experiencing any green screen issues and any steps to rectify?

*just noticed update* will give this a try for my issues. Thanks.
[Shield Android TV Android Development] lartomar2002:
Others have mentioned this same issue for the last 4 or 5 pages of this thread and have posted their solution.
[Shield Android TV Android Development] KING SKILLZ:
edit stated disregard!
[Shield Android TV Android Development] hausmanis:
Zulu your a hero, flashed this and works wounders for me !

Thanks alot and keep up the good work this rom is amazing
[Shield Android TV Android Development] banderos101:
Wow, bought another, considering its closed source nature and the headaches that tend to come with it, when devving on such a device, im surprised, pleasantly so, glad to see you've not given up, dont think anyone would of blamed ya either, stupid closed source.......it is a shame that theres no nexus player thats as powerfull with similar connections

Anyway, i hope you can be patient with me one last time, two questions

Do we need to update stock firmware to 2.1 before flashing the latest 2.1 full, or can we flash 2.1 full ontop of 1.3?

Ive already flashed twrp, should i reflash stock recovery before installing 2.1 full through fastboot?
[Shield Android TV Android Development] tailslol:
heh yes you need to get rid of twrp and update everything to 2.1 now the same way you downgraded....

if you already downgraded and put twrp you better use the old version you downgraded for i think.

twrp is handy to add packages you want. (atmos dolby,walkman music player...)
[Shield Android TV Android Development] banderos101:
Cheers tails, in every device i have, nearly all have custom roms and custom recovery, its flashing stock firmware and stock fastboot/recovery thats all new to me.......another good thing about the custom recovery, which is the most important to me, is the complete mirror image backup ability

Tails, you've been more then patient with my barrage of questions over the last couple of days, and i thankyou for it, as much as i thank ya for the help, cheers mate

---------- Post added at 09:05 AM ---------- Previous post was at 08:26 AM ----------

Dont know if this solution or situation is the same, but when you downgraded from 2.0 to 1.3, did you flash the images manually, one at a time, or did you use the bat file inside the same folder

What happen to me, i manually flashed the images individually, rebooted and got the green screen issue, another member asked how i had flashed the images?whether i used the provided bat file? Which i had'nt

Long story short, i redid the downgrade using the bat file this time(alot quicker), rebooted, and no more green screen

Dont know what your setup is, if you've already used the bat file or not, but if you havent, and if you can, try the bat file, doesnt take long, and its pretty simple.......and hopefully, it works for you as it did mine
[Shield Android TV Android Development] zulu99:
I suggest to upgrade to last 2.1 stock firmware.

I suggest the rooted one that is better, but just to be sure, in reality there is no differences you can use also the stock 2.1

Anyway the stock 2.1 rooted firmware is this: https://developer.nvidia.com/shield-developer-os-images

Download and install with fastboot.

After, when you are on stock 2.1

With fastboot you can install Full Android just update the system.img to have all.

fastboot flash system system.img

fastboot -w

fastboot reboot

For now you can avoid custom recovery. If you need to install other packages you can use the tool FlashFire made by ChainFire

http://xdaforums.com/general/paid-software/flashfire-t3075433

With FlashFire, install, backup and all others actions are working from internal sd card. For this operations use always the internal sdcard otherwise it not install.

P.S.

When you have all others parts stock and you change only the system.img you can't brick

So you can experiment what you want. The important part for now is to have all others parts stock.

The full Android Firmware 2.1 was made ontop stock 2.1, so the most stock compatible parts are from stock 2.1
[Shield Android TV Android Development] duanim:
Workings snappy in my pro version, so simple to used fastboot,detect my 500gb,just first impression

Zulu99 yes are god viva Italy.
[Shield Android TV Android Development] zulu99:
Strange that Nvidia don't sell the device in Italy. In Italy we have a good tech support for Shield TV :)

I am one of the leading sponsors for Shield TV in Italy :)

Apart joke, this device is really the most powerful device that i have never see. It's real a shame use it with the limited Android Tv version.

Please nvidia, help us to continue to have full Android forever.

p.s.

In this days netflix was arrived also in italy.
[Shield Android TV Android Development] amarok:
How can I change from 1.8 to 2.1 stock without the box to destroy?

I need first to 1.3 and then back to 2.1 stock ?
[Shield Android TV Android Development] Grippen50:
I think the best to do from now on when a new FW is released by Nvidia is

1. Backup everything as Zulu99 suggested or any other app that you can find on the store to an SD card.

2. Wait for Zulu99 to release the correspondent modded image file.

3. Install Nvidia new FW

4. Install correspondent Modded image by Zulu99

5. Place all backup data back into the device
[Shield Android TV Android Development] zulu99:
You can simply install the last stock 2.1 version and after install with fastboot my last system.img

That's all

remain all others parts stock and you are very sure.

To install things installable from recovery, you can simply use the FlashFire tool that is an app that work like a recovery but from inside the firmware. It not change recovery but install recovery stuff. Is a magic tool made by the Genius ChainFire

Install things from internal storage, all others external disks are not supported for now. ( but is not a problem )

https://www.youtube.com/watch?v=p0q0ytHkzoI

- I SUGGEST THIS TO BE SUPER SURE -

IN THE UPDATE PROCESS, IF YOU HAVE ALREADY INSTALLED THE TWRP RECOVERY, I SUGGEST TO GO BACK TO 1.3 STOCK, UPDATED TO 2.1 STOCK AND AFTER INSTALL MY SYSTEM.IMG
[Shield Android TV Android Development] amarok:
has not zulu brick his box last with flash at 2.1 nvidia from 1.8 ?
[Shield Android TV Android Development] zulu99:
I bricked because i used some times the TWRP recovery on stock 2.1 firmware with a crazy usb disk ( this was happened to me )

But i know also others that bricked because used the TWRP recovery on 2.1 firmware in normal way, without strange things connected.

- I SUGGEST THIS TO BE SUPER SURE -

IN THE UPDATE PROCESS, IF YOU HAVE ALREADY INSTALLED THE TWRP RECOVERY, I SUGGEST TO GO BACK TO 1.3 STOCK, UPDATED TO 2.1 STOCK AND AFTER INSTALL MY SYSTEM.IMG
[Shield Android TV Android Development] amarok:
sorry

I ask again for safety's I have 1.8 with TWRP from your howto

I flash now 1.3 stock ---> 2.1 stock ---> and then your new system.img?
[Shield Android TV Android Development] zulu99:
YES becauae i think that TWRP can create problems with 2.1 update

And because in this way you follow the normal update process invented from Nvidia.
[Shield Android TV Android Development] amarok:
problems when i flash from 1,8 to 2.1 stock ?

sorry my english
[Shield Android TV Android Development] zulu99:
If you have TWRP recovery you can have problems. This not happened to all, but to be sure:

Go back to 1.3 stock, update to 2.1 stock and after install my last system.img
[Shield Android TV Android Development] amarok:
okay thanks
[Shield Android TV Android Development] netvlada:
Thanks zulu for new sw:good:

From new sw, can we go for Nvidia update or not?

If need to send Shield for RMA ,we need to flash original sw?

New sw is without any kind of TWRP?

Latest Nvidia HW codecs from 2.1 are inside your new sw ?

With FlashFire we can to backup all from Shield?
[Shield Android TV Android Development] tailslol:
yes i think so.so you get rid of twrp before 2.1

---------- Post added at 02:17 PM ---------- Previous post was at 02:12 PM ----------

yes it is build from 2.1 sources so yes it got the codecs.

so yes you can update from nvidia before put the full android 2.1

and yes again no twrp.

with flashfire i dont know,depends if it works with nvidia stock firmware or not.
[Shield Android TV Android Development] amarok:
brick the 2. box.

flash with linux

flash not with batch.

flash with commandline

flash from 1.8 to 1.3 stock it was okay

box reboot perfect

check "oem unlock"

flash from 1,3 stock to 2,1 dev rom

linux say okay.

box dont reboot

box dont speak with me

box dont have signal on hdmi

BRICK
[Shield Android TV Android Development] tailslol:
outch,sorry i guess most of us flash on windows but

nvidia said 2.1 can brick if something wrong with your box,you should rma them.
[Shield Android TV Android Development] amarok:
flash with linux work perfect. but not flash with shield :(

i dont see a error in the commandline. flash wos okay
[Shield Android TV Android Development] netvlada:
Does Nvidia OTA upgrade works from the latest Zulu sw?
[Shield Android TV Android Development] tailslol:
no,nvidia support only android tv.
[Shield Android TV Android Development] banderos101:
Can i not update normally from 1.3 to 2.1, using the stock android updater?

Edit

Just went to check it out, and it looks like it only gives me the option to update to 1.4, so if its incremental, i might end up having to download three firmwares to get to 2.1, so i guess fastboot way it is.

Are there any mirrors for the stock 2.1 images, or do we have no choice but to register?

---------- Post added at 03:05 PM ---------- Previous post was at 02:31 PM ----------

Have you just left it on?have you tried to reboot it manually?

The more info, the better chance someone might be able to help

From this link

http://nv-tegra.nvidia.com/gitweb/?...ob_plain;f=README_SHIELD;hb=rel-22r18-partner

See if you can at least get back into bootloader and try to reflash 1.3, to hopefully get something back and try again......assuming its not completely bricked

Theres a few methods it looks like to get into bootloader

"SW method:

Boot to android home screen Connect the device to linux system Open terminal(on linux) Type "adb reboot bootloader" in terminal

HW method:

Disconnect power cable Insert USB OTG cable and make sure to connect other end to a host PC Connect power cable to SHIELD Quickly start pressing power button for ~3 seconds Do not hold the button and connect power supply afterwards HDMI TV should be always connected to SHIELD

Alternative method:

Perform software shutdown on SHIELD by holding Power button for 10 seconds Connect USB OTG cable to SHIELD Start pressing power button for 3 seconds HDMI TV should be always connected to SHIELD"
[Shield Android TV Android Development] kdb424:
I would register if I were you. It's free, you can use a throw away email if you really care, and you'll be able to access all firmwares because 6.0 is around the corner, you'll probably want it anyways. I'm pretty dang stable on 1.8, and need twrp, so I'll not be upgrading myself till recoveries catch up. Can someone test if youtube streaming works in the new update? Streaming TO youtube, not from that is.
[Shield Android TV Android Development] banderos101:
You've made me think now......as i need twrp too, as im gonna be testing out xposed modules and one in particular, xprivacy, i know is probably gonna eventually give me a bootloop as i test and modify settings, thats where a recovery, having made incremental backups that boots before android comes in handy, i just realised that the impressive tool flashfire wont help me here in this situation (i do wanna test out flasfire though, sounds impressive of what little ive read so far)

So damn, it looks like i also have to wait for a working 2.1 twrp.........im getting antsy now:), cant wait to start putting this thing through its paces.........apart from the closed source nature, this is an impressive piece of kit
[Shield Android TV Android Development] kdb424:
Unless I hear of a specific reason to upgrade, I'm going to stay on 1.8 as it's fully featured it would seem. I am very glad for the 2.1 version as it's going to be easier to new people to install if they don't need twrp, and now there is a reason to have twrp on a newer firmware, but otherwise, if you have 1.8, at least for now, I can't see a reason to change to a leter version.
[Shield Android TV Android Development] amarok:
[MENTION=3385762]banderos101[/MENTION]

after i flash from 1.3 to 2.1 (devel 2.1) and all messages say OKAY i make "fastboot reboot".

The box have power but i cant connect it and no HDMI output. The box dont work. Powermeter say 2,9 Watt .

3. box

have just a new box flashed with the same rom and this box is okay.

flash from "2.1 to 2.1 stock devel root rom" and then system.img from zulu. works perfect..

as way as with the 2. box
[Shield Android TV Android Development] tailslol:
I will do the same because my shield is set up as my main rig in the living room.

And I got everything needed.
[Shield Android TV Android Development] lartomar2002:
I am not going to use this rom or try to root my shield until android 6.0 is out. There is a lot of confusion due to several factors but not really anyone persons fault. I know [MENTION=308669]Zulu[/MENTION] means well and tries hard but sometimes I can not follow his english. There are to many version numbers flying around and members are not sure which version number applies what, the rom or the shield firmware. Some members meaning well reply to help with a problem failed to read the problem correctly and will leave out necessary information. And since I have not had lot of practice using adb I think I will just wait until everything smooths out. I can not afford a bricked device. I will coninue to follow the thread and I do want to thank everyone on here. Thanks
