I'm usually good at recovering my devices since I've had various Android devices since 2010. I'm stuck with how to recover my Shield since it doesn't have a physical buttons. How can I boot directly into the bootloader or recovery? I've done it a few times by accident by rubbing my finger across the power button but can't figure out how to do now. ADB or Fastboot won't detect it at all, I just get a black screen and my TV says "no output".
I had rooted my Shield but kept the stock OS and had TWRP installed but saw no use for root. The 1.4 OS update had been sitting on my homescreen for weeks so I finally decided to revert back to stock and upgrade. I flashed the stock bootloader via fastboot and then flashed the system image but didn't touch userdata. After booting up some things would be goofy (Netflix would get to either 25% or 99% and the audio would play but the video would be stuck on the loading screen, Grid streaming would load the game but would display a green screen but the audio would play in the background) but I didn't want to wipe it yet because I didn't backup Kodi yet.
I saw that there was a 2.0 OS update available and I knew it should work now since I had the stock recovery so I downloaded it and applied it, it verified the image and then rebooted to the stock recovery and proceeded to flash the image. It got about 99% (or maybe 100% done, I wasn't paying attention) and then next thing I notice I just saw a black screen. I thought maybe it was upgrading something or reinitializing something so I waited about 5 minutes and still nothing. Rebooted and got the same thing.
Anyone know if this is recoverable or should I just RMA it?
I'm in the same boat. I was running pure stock from day one (only bought this thing two weeks ago).
After installing 2.0 update last night, the device powers on (green light) but no signal from HDMI. Tried another TV and bypassed receiver (as per forum suggestion).
Computer does not detect when connected with USB. Tried to do HW boot into recovery, does not seem to work.
I have started the RMA process but I'm still trying to get this thing to boot into recovery.
Seems like this has happened to a few other users also over at the geforce forums.
try to reflash it with nvidia images.
if you cant boot to fastboot try this.
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

I did the RMA, only took a few days. The new unit came and auto-updated to 2.0. It worked fine.
I spoke with support today regarding the update, they had this to say;
[12:51:41 PM] : Only few devices, which already had some issues, got bricked with 2.0 update. This was already predicted by NVIDIA, just to get those devices replaced for the customers.
[12:52:45 PM] : Few devices had some hardware issues, but they were working fine. To make that issue prominent and get them detected and to replace them, NVIDIA has released 2.0 update.
[12:53:34 PM] : For other devices, 2.0 update will add many new features and will boost the performance. But for those lot, it will brick them
[12:55:38 PM] : It was a strategy from NVIDIA to provide perfect devices to our customers

Take that with a grain of salt of course.
Defective is defective I guess... the RMA was fast at least.
So they bricked the defective ones on purpose just to get them out of use?
I'm in the process of RMAing mine now, they want a lot of information hahaha
God this from support since mine have black screen, it did not help me and my are sent for rma but i might help other.
As part of troubleshooting steps, please try the below mentioned steps and see if that fixes the issue.
-> Unplug all the cables and keep the device off for good 2-3 minutes.
-> Plug the Power cable, controller through USB (Wired) and Ethernet cable to the ATV. Do not connect HDMI cable.
-> The device will power on. Keep it idle for about 5 minutes and keep tapping A button on the controller. Continue tapping for about a few seconds.
-> Now leave the device is this state without the HDMI cable for good 15 to 20 minutes and plug the HDMI cable.
-> See if the ATV displays any output.
I just got my replacement unit, so I'm good. I have two shield controllers now

Nvidia tech chat support, before they made a rma on my box.
But just got my replacement box today
How hard was it to get a replacement? I am afraid to do anything to mine. Asked nvidia if unlocking the bootloader or rooting the device voids the warranty since they show you how on their website. Their response was that doing either allows them to reject your return under warranty. Just looking for anyones input on their encounter with doing a rma if something should happen.
You may have screwed yourself over by telling them that you did that. I had mine rooted and unlocked also, except mine was unrooted when it bricked itself but the bootloader was still unlocked. I made not mention of rooting/unlocking and it was extremely simple to get a replacement.
No mine is still stock. Just received a replacement from amazon since it bricked itself doing the 2.1 update. Was just wondering what they had to say about the situation. Was consindering flashing the 2.1 full rom, but was worried what would happen if it bricked and had to do a rma. Would not say anything to them about unlocking the bootloader or flashing it. Was wondering if they could detect if anything was modified on it since I see everyone gets a black screen and can't access the console with fastboot. Do they have some way of accessing the system or are they also locked out like we are? Just want to be sure I can get a rma if something happens. A $300 Pro model is a lot to screw up. Support was great to work with, but didnt get as far as a rma since it was still in amazon's 30 day return window. Got a new one in 2 days since I have prime. I just asked what there policy was and not mentioned anything about a bad console.
---------- Post added at 06:13 PM ---------- Previous post was at 06:07 PM ----------
Its just a shame that they offer the tools for developers, but turn around and say that it voids the consoles warranty.
I'm sure they are able to use a UART bridge (serial console) to get into it but I doubt they care enough, like I said mine had an unlocked bootloader but I haven't heard anything back from them yet regarding it.
OMG I fell to their trick to brick my device.... I just did my RMA today, they asked me to do alot things; speed test, model number, turn off, unplug power and hdmi, hold power for 30 sec, plug in power for 2-3 mins, plug in hdmi, then found out no signal on my screen...I assumed it's brick now. i attempted to revive the unit but it doesn't seem to work... Then they had me filled out form, provide snapshot of p/n and s/n numbers... and send them my invoice of purchase.
every time it gets new firmware it loses netflix 4k and this is the fix for it

Yes I have read all posts regarding "Screen Of Death" issue and i have tried all the suggestions. But still, my 10.1 won' t turn on. I have left it drain the bat for 2 days now.
Even if i plug it to the charger there is no sign of battery charging. Hence just blank black screen. any other idea before I have to go to the Service Center. Thanks. Any help would be appreciated.....
Connect the USB to a Windows computer and press Power + Volume Up for 30seconds. Do you hear a Windows "new hardware found" sound?
Thanks... Tried... Still fail. My PC only signaling found new hardware but fail the installation process. I guess because the tab is still not ON. Help....
It seems my PC recognizes the tab but can't find the driver. I can also feel "warm" near the power button area when i connect it to any electricity but still no TURN ON or BATTERY CHARGING INDICATION.
Have you tried to charge it with the wall charger for at least 2hrs and then unplug it and hold powerbutton 10 sec?

Actually, that is what I was expecting as result.
The Power + Volume Up enables the nvflash APX mode, the screen remains totally black. I simply wanted to know if the tablet works and the culprit is just the screen. From what you say, we get the expected results... Windows detects the new hardware so the tablet works.
Now try the opposite: Power + Volume Down, hold it for 30seconds.
If you don't see nothing on the screen, it is probably a screen contact that got lose... you need to service it by Samsung.
yes done that. Still not ON. When I plug it I can feel it is working since I can feel "the warm" but screen still is blank
Then you already know what to do.
No biggie, Samsung will send you a replacement for sure.

yes. In fact now the APX is still working trying to find " a new hardware ". Should I cancel it and try the POWER+VOL DOWN now?
Yes, go ahead.
DONE the Power + Volume Down still not ON. BTW the APX Could not find any driver? Is it normal. Before this happens in fact i can transfer any file with my PC through MTP. Thanks again for your help. Hopefully you still know any other solution.... Keep waiting
The APX driver is included into nvflash package, it does not matter if you install it or not at this point. The advantage of this test is that the APX mode keeps the screen off in purpose, while allowing you to flash the tablet through a CMD window (only if you have an unlocked bootloader). We used this trick to determine if the core of your tablet works... we wanted to isolate the problem related to your screen.
I recommend you to contact Samsung and have the tablet serviced. Some screens lose a contact point when you drop the tablet by accident or if a soldering point is weak... The heat generated inside is enough sometimes to sever a lose circuit connection. Either ways, you do NOT want to keep this tablet.
I hope you did not flashed the tablet with some custom ROM, or else Samsung might void your warranty.
OK. Then the only thing i can do is go to SC.......Hmmmmm I am still using stock rom but unfortunately i did root the tab already. Is it bad judgement??? Thanks anyway.
I really hope it is only the screen connection lose issue. But just for curiousity. If only the screen keeps OFF, does it mean I actually can still check that my gtalk on the tab still connects? How this thing works??? since i just check with my phone my gtalk on tab is off.
You ordered the tablet online from Samsung or you bought it from a retailer like Best Buy?
I bought it from retailer. BTW is there any kind of USB JIG for the tab similar to SGSII? I just thought maybe this can help solve the screen of death issue. Ha ha ha ....
Perfect, just go see the store and explain to them nicely the issue. I'm sure they will exchange it for you.
Forget about the JIG or anything else, your screen is gone wacko... What you do now is try to force a blind guy drive a car... Just go exchange the tablet.
Ok I' ll do that. Thanks for your info and help. Hopefully problem will be solved soon.
I had the same issue but I couldn't return to the store so I went through support. They don't have parts yet so they just send you a different unit. In total it took 2.5 weeks for me and I ended up with an unlocked unit

Damn, it took 2.5 weeks to get a new unit?
The good news is, it's recoverable. The bad news is, it's going to take a long time.
Keep it off the charger.
Hold down the power button to get it cycling through APX mode while plugged into your PC (can hear the USB connection sound in Windows).
Tape the power switch down, verify it's still going into APX mode after taped, then unplug it.
Leave the tablet alone for a few days. Think about puppies, chocolate, bouncing breasts, whatever makes you happy, and forget about the Tab.
Come back, plug it back into the PC, see if you still hear it connect. If so, walk away again, come back the next day.
When it finally stops going into APX mode, plug it into a wall charger and leave it alone for about an hour, it should start charging normally, and once it's got charge showing, it'll power up normally.
Rule of thumb is it'll take about a full day for every 10% of charge that was on the battery when it went down, if you keep the power button taped down.
Just laying this down somewhere so its out there and not cluttering up Thing O Doom's thread.
Update: Got a refund due to them being OOS to replace. Oh well, no transformer for me...
Had some problems with my TF101, seems its a hardware fault with the USB port.
First cable: Caused Reboot then semi bootloop
Second cable: Disabled Power Button.
Cant seem to find any other people with these problems so am going to return it and get a replacement seeing how Ive just bought case, screen protectors, silicon skin etc.
Like the tablet and for the price I got it for I defo want a fixed unit!
History of posts in other thread:
First Cable:
After booting and the usb cable is attached it 'crashes' back to the main EEEPC logo screen and seems to be bootlooping except that it doesnt get to the boot animation. Just logo > black screen > logo > black screen.
Once cable is removed it boots and operates as normal until cable is plugged back in again.
I can get to recovery and use that no problem, even adb, but no go when booting into android.
Notes:
It worked before the rooting as was using it to do the rooting
If I plug it in at ANY point itll do it, powered off, boot animation, launcher etc
adb works fine in recovery
Havnt flashed a new rom yet as just got back from work
Update 1: Factory rest in TWRP = Problem still persists
Update 2: Wiped all partition (except sd) and restored backup after first root = Upon first connection it 'crashed' but this time rebooted to the os. This time Battery was 0% and crashed again when going into settings.
Update 3: Holy s*** - It does it even when not plugged into a PC! Just plugged the cable in by itself and it did it WTF!
Either the cable or connector is faulty Will have to try another cable but wont get one till next week now. If it does the same Im gonna have to send tablet back. FFS.
It must be cable as AC fits nice and tight (first time I used it was before rooting) while the USB is slightly loose and not as 'snug'
Why does it work fine in recovery though?

Click to collapse
Looking at my amazon purchase Im thinking it isnt a genuine cable and cheapo knock-off (wasnt cheap cash-wise!)
Wondering if its something to do with the charging pins and it trying to charge but do data at the same time causing it to 'crash'. Could have been knocked out of place as the first time id used it was to use the root tool.
Anyway, when my new cable arrives Ill move this to a new thread if needed but for now Ill leave the post here in case any one else stumbles across it.

Second Cable
Well, its definitely looking a hardware problem as this new cable that came today does similar except that it only turns the screen off but doesnt reboot it. Cant turn the screen on until the cable is removed.
I got it connected to PC with the new cable as well as adb was working etc but no screen
Going to return it for a replacement if I can manage to get it returned to stock rom and recovery.
Everything else on the tablet works fine except the one thing I needed to work 100% lol just my luck
;edit; ...wtf...Flashed to stock and both cables are new cable is working fine...Will have to see wth is going on later when I get back from work
;edit2; Nope it just disables the power button so I cant turn the screen back on. This feckers going back!

Hello everyone!
I was using the Shield (pro model, 500gb) and suddenly it won't respond to the remote control. I turned the Shild off and then tried to turn it on, but it won't. When I try to turn it on the shield button turns green but only for 1 second and then turns off. Nothing is displayed on the TV. I have tried many times turning on the Shield and it only turns green the button for one second and then turns off.
I have tried the instructions provided here, but to no avail: http://support-shield.nvidia.com/android-tv-user-guide/index.htm#t=Reset_SHIELD.htm
Has anyone encontered this issue and resolved it? Don't know how to recover my device now
Thanks a lot for your help!
Best regards,
David.

Im not a expert in this sphere, but according your written the power button on Shield not lights and this happened without your interfering, my guessing and opinion sounds like you have hardware problem, this symptoms not sounds like software. Try this one and or not I would go sending back by warranty!

Hello again!
I tried what is mentioned on the video but it does not enter into bootloader. The video mentions to press the nvidia button two times and in the first time the green light keeps on. In my case, when I press the first time, even if I keep pressing, the green light just turns on for 1 second and goes off. The second time it is the same, and actually nothing happens
Anyone has encountered this issue?
thanks!
Did you manage to eventually get this sorted?
I have an almost identical problem; the remote for my SATV Pro stopped responding, mid-session, one day.
I had to pull the plug and it would no longer boot, thereafter.
The light will stay on indefinitely, it seems - I left it on overnight to test.
It won't enter the bootloader menu, either; if I hold the power button for 6 seconds, the light switches off and I can still hear the harddrive.
when trying the push button method do not forget,the USB and HDMI should be plugged to each device before start. me I just press for start then I instantly press again and hold,works well .
Did you figure out what happened and if there is a fix for this? My Nvidia Shield Pro is having the exact issue and unfortunately my unit is a month over the warranty period =(.
Same light flash for a second after power, but nothing after. I'm thinking it must be a hardware issue, but how to troubleshoot it? Wish an nVidia engineer would help out.
My 2015 Shield 16GB went dark today and I have the LED on for 6-10 seconds after replugging, and then it shuts itself off. I only see the green Shield logo for few seconds. Tried going into bootloader, but there it too shuts down after few seconds...
same her mine just gave up.
Was Shield Experience 8.2.1 recently released or am I just seeing it now for some reason? Maybe that's what caused your problems?
edit: seems like there are issues with the TV trying to go from 7 directly to 8.2.1. See the sticky:
https://www.nvidia.com/en-us/geforc...ield-experience-upgrade-821released-11162020/
after one night unplugged i got it booting again and it run for about 10 minutes or so.
efter that i have now tried toapply new cooling paste and even tried with another power adapter, but noting seems to help so far.
and as some one else up there said, i can still hear the hdd spin
A very similar thing has happened to me but maybe my difference can shed light on this issue?
I was cleaning (sweeping specifically) and accidentally turned the shield on. I pressed the touch button on the front of the shield to put it back to sleep and I then heard a *pop* sound. After that the shield will only turn on for a second, the green light will come on for a second and then it will switch off.
I opened it up (pretty easy with just my finger nails even) and I can hear sounds coming from the mainboard when I plug it in, like it's still receiving power even though it wont turn on.
I have little to no experience repairing electronics but my assumtion is I discharged enough static to blow the power button board on the front of shield unit.
Also to add, the shield unit will not respond to the inputs of a controller or a keyboard that has been paired with it.
I identified the infinitesimally thin wires that connect the touch power button to the main board but they dont seem to be damaged themselves - I plugged the power supply in while each side was disconnected and the shield unit turned on when I reconnected the wires.
I'm going to assume that if I can replace the power button board on the front of the unit it will work again but I'm not sure and cant be sure unless I can get a spare part.
Or maybe I should just take it to a repair shop?
Has anyone managed to get their unit working properly after this specific issue.
Side note: it's strange how many others have this exact same issue in this exact month isnt it?
Just following up a little bit.
I got a new power supply from Ebay to see if that would make a difference.
It did not - the power supply is not the issue.
Oh just to add - I tried cloning the original drive but I was still able to read it on my computer and the drive-clone didn't change the outcome so that wasnt the issue either.

I turned mine off at the device last night and, pop, a huge static discharge from my finger. My Shield now exhibits the same behavior as everyone else in this thread.
Just wondering if you or anyone else every figured out a fix? Possibly blow fuse or capacitor in the power circuitry?
No change in status.
I'd like to still fix mine but I ended up buying a mini PC, which is a million times better than a proprietary-hardware device.
It's not locked down like an android only device (even though it runs on win10) and I can do much more with it than just watch movies and play android games/apps.
Anyway if anyone else can find a solution to this that'd be great.

Did you remember to connect it to a PC via USB first?
Cause if not... Well theres your first problem.
Same here, stuck at circles........
Nvidia Shield TV Pro 16GB 4K HDR
All right guys, I'm back with the following steps
If you own a SHIELD Controller
• Unplug SHIELD TV.
• Connect SHIELD controller to SHIELD TV with a USB cable (use port closest to HDMI).
• While holding the A and B buttons at the same time, connect power to SHIELD TV.
If you do not own a SHIELD controller
• Unplug SHIELD TV.
• Connect a USB keyboard directly to SHIELD TV (use port closest to HDMI)
• While holding the "A" and "B" keys down at the same time, connect power to SHIELD TV.
• Once you enter Fast Boot mode, on the keyboard use the "X" and "Y" keys to navigate the menu and "A" to select
Use the X and Y buttons on the controller to move to "Boot recovery kernel".
3. Press the A button to select "Boot Recovery Kernel".
4. You may see the dead Android robot on screen. This is expected behavior. If so, press B button on the controller.
5. You will see Android Recovery Menu.
6. Use the X and Y buttons on the controller to move to "wipe data/factory reset".
7. Press the A button to select "wipe data/factory reset".
8. After process select "reboot system now".
8. SHIELD will boot to home screen.
Do the factory reset
It will bring you back to recovery
Select "Continue"
device will process and reboot like new
Hope this works....ENJOY
It did for me
I received the above info while chatting with Nvidias tech support
Hi all,
I have the Shield Pro, running 5.1, and it won't start
It was working fine yesterday, but when I got home from work this evening, it was unresponsive. The power light was stuck on, but would not respond to any controller input or, as far as I can tell, any USB input.
I pulled the power out, and plugged it back in, and the light came on instantly. No display on the TV. I plugged it into my PC, but Windows doesn't see anything attached (I have tried multiple cables). If I hold the power button for five seconds, the device just turns off. If I touch the power button even just briefly, the green light comes back on. I can't get into Fastboot or anything. There is no HDMI output at all.
This is, naturally, really quite annoying.
However, after having it hooked up to my PC via USB for a while (not sure how long, sorry!), my computer bleeped like it does when a new USB device has been discovered, and bingo! I now have an "APX" device, with no drivers installed.
So. Who knows about APX mode for this thing?
I'm pretty sure APX is a low level recovery mode.. I recall reading that elsewhere.
go to the developers nvidia site amd search on how to reflash via apx
yeah, I had to use it on my old LG Optimus 2X, back in the day. There's nothing on the nVidia developer site about using it though

Apx mode ( and yes without drivers - couldn't even find around in Internet...) on pc ×device manager× shows me on my 500gb console when I removing internal shdd and connected with pc whiteout shdd (one day nothing to do and decide need open and have look what is inside in console...shdd, motherboard, cooler etc) . Another words sounds those symptoms very similar with my tests, but in my case that was mine experiments/investigations/discovery and your looks like you have some serious storage problem or kind of problem relaited with - can't read os or even bootloader which is on 500gb shdd or flash memory modul on 16gb.

yeah, I had to use it on my old LG Optimus 2X, back in the day. There's nothing on the nVidia developer site about using it though

after googling for a bit , i saw some references to the shield tablet, i think someone had an APX driver, maybe you could try that?
I could do, but APX mode is really, really dangerous. You need to know byte offsets and all that :S

if you know apx and you have all necessary stuff from Nvidia (which is not provided for public) you can replace internal drive or even ssd by installing bootloader, recovery, os etc straight on new drive from pc which is main factor why we can't swap them so easily, like 1 - 2tb drive or ssd - which would be fantastic ?. P.s. Something simular protection is for Xbox360 drives.

if that's the case you might have to send it for a warranty repair.. better not playing around if it's under warranty.
an idea for apx
move your shdd from shield and connect to pc then use this program(R-Studio 8.0) or other to restore date on u shdd I think it most work good luck

I have tab p7500 and have this problem apx only jtag help me in apx mode you should now wish sbl for tegra x1 and have nvflash for shield pro sorey for my English the easy way use jtag or tray to restore data in shdd
would there be a way to just dd- flash a new recovery withthe hdd removed from the unit? I am having te same no logo, no bootloader issue and am trying to either find apx drivers (non-existent) or a workaround. There has to be a way.....
i have the same question. My intrest is more in tinkering with the tegra x1 exploit in order to get a different root solution not contingent on nvidias closed source crap. I'm running a 2015 foster model and it is getting increasingly difficult to find tutorials on that system specifically with the newer updates. +i am interested in learning the process to exchange the hdd and mopy and manipulate the widevine keys that don't work on mine after the forced 7.2.3 update that occured with all update sofware removed from my system that also fried my controller with a botched firmware update that is blacklisted and not mentioned on the internet except people asking and all replies deleted. you know general unfettered access to the system without the bootloaders say so . All of this should now be possible now that the real hackers have gotten involved and decided they want to promote this exploit for homebrew it has caused several low level apx drivers to popup in corners ive found myself in from time to time if somebody will just get them to do it for the shield tv instead of the shield tab and the switch it is proven to work.
Hello,
I have tried the search feature to no avail in regards to following the appropriate troubleshooting steps to ensure that I can at least boot to fastboot, however I cannot boot into the fastboot menu.
These are the steps I have tried so far:
With only the Power, HDMI, and MicroUSB to USB connected
1) Disconnect the Power
2) Hold Nvidia Button Down
3) Reconnect the Power
4) Release Nvidia Button (~2 seconds)
5) Press and Hold Nvidia Button (~5 seconds)
again, I am still at a black screen with no output whatsoever.
I have also tried allowing a full power cycle (where the Nvidia TV is left alone for approximately 15 minutes)
I also tried the Nvidia chat support who suggested that I try plugging in the controller and pressing the A and B buttons simultaneously, etc. to no avail.
Is there anyway to force a fastboot interaction via console? I would just like to reflash to stock. Even if this method requires altering the hardware via soldering.
You need to connect (Depending on your Model), either a MicroUSB, (2015, 16Gb, Pro / 2017 Pro), or a Male Type "A" to Male Type "A" (2017, 16Gb) between the Shield TV, and some Computer. I prefer to use a Netbook running Win7. But, This should be equally valid for Linux, and Mac.
So with you PC / Netbook turned on, and connected to the Shield TV via USB. Leave the USB style plug in the Shield and if possible yank the Brick (Wall Wort), instead.
Start a Two beat count.... 1... 2... 1... 2... (It would work better if you had a Clock that had a Second Hand.) But once you have this 'beat' drop in the Wall Wort on count Two. And THEN tap the Power Button, hold this for Three counts, than release (Pro Uses might note the SSHD will start to wake at this very moment), and immediately re tap, and hold the Power Button till you enter the Recovery Mode.
This is a very time sensitive attack, and 2/3s of the time will land you at the nVIDIA Logo. (Where available), and your only option here will be to start over again. Or boot completely into Android, and use
$ adb reboot recovery
To force the Device to reboot into recovery mode.

I appreciate your reply but again I am not getting any output what so ever after attempting to apply an update to the Nvidia Shield TV. Is there any procedure to force the device to flash even over hardware?
Depends on if you have a 16Gb or not...
Let's put it this way, if you have a 16Gb it's pretty a wrap. If you have a Pro then you have a few options. Like ripping the SSHD out of it, and attaching it inside a PC running Linux. Or at the least a PC running a live install of Linux.
Which is critical to maintain your private keys. Everything else can be discarded. But, not those DRM Keys. Not if you plan on ever using anything that will need Widevine L1.*
Now that is wholy your choice to make. Either way you will probably want to down that Torrent, which is a backup of someone else's Shield TV. It WILL reserect your Device. But, if you haven't managed to recover your own Keys you will not be able to rewrite them back later on. And, the upshot of that will be the loss of all Widevine L1 Services. e.g. Amazon, Netflix etc...**

I have the 16GB model and I am not sure what would be the best way of resurrecting my device upon a bootloader that is corrupt.
I think your forked... The only way it could possibly be done would be to pull the ROM Chip, and clone this in a not so dissimilar fashion, and then flash a working 'Image' back onto it. Before resoldering said Chip back onto the Mainboard.
Again, Not something just anyone could do.
Look I have no idea how old your Shield is, or if you still have, or have ever had any Warranty Rights to begin with. Assuming that you still had any of these 'Rights'. I would recommend playing dumb, and attempt an RMA, and pray that it works out.
If that also fails, then I guess you are what is termed as being SoL...

Thanks Ichijoe I tried to also to boot into recovery using alt + print screen + i (on an external keyboard) in order to restore the device however this did not work.
I wanted to pull the ROM chip but I don't know of any software available to allow such a feat. Does anyone have any information on utilizing J1D1 or J1D2?

This is getting oh so over my head now. So take it for what it's worth. But, as I understand it One would need an EEPROM Programer, and the "Software" would just be written as a RAW Data. Again not entirely, not unlike taking a certain 'Raw' backup that someone tossed up to the Net as a Torrent File. For bricked Pro users.
Pulling the ROM Chip off the Board is not something just anyone can do without destroying the Chip, the Mainboard, or both. The EEPROM Programmer is also an additional cost, of which I would have no clue. Needless to say, in the long run it's just unfortunate as it is, to just get a new Shield.

let's try this way :
unplug your power cable of the shield tv
plug your lan cable on your shield tv ( be sure DHCP on your local network is turning on)
plug your new shield controller on the usb port of the shield
plug the power cable and DON'T TOUCH THE CONTROLLER for 1 minute
now hold down home button and left button ( on the X) for 3 seconds
normally you can see the blue signal of the controller 3 times. this mean the procedure working good ( if not retry till it work)
now let your shield working around 2 hours ( depend of your download speed)
afetr this time, normally the shield finish downloading the update and restart... now you normally can see the screen
