Nvidia Shield TV 2015 no fastboot, no ADB, Broken System - Shield Android TV General

Hi @All:
i´ve got a Nvidia Shield TV of 2015, which was with a broken Systemimage.
I took some Updates from the Nvidia Developer´s Page, but nothing helps.
It hang always by the Nvidia Bootlogo, and after any time it takes a reboot.
The Recovery Kernel was also damaged. It was shown by the Dead Androidman.
Yesterday i flashed it, so i think, with a wrong image.
Now it won´t boot. There is no Picture or anything.
Also no Fastboot or ADB.
NOTHING!!!!
Have anyone an Idea, what i can do?
Is it possible to get an Image directly to the eMMC?
Greatings
Sebastian

Use a keyboard or game controller to boot fast boot
Try to recover through recovery image on shield forums

Bricked my Fire TV Stick 1?

Hi there!
I think I may have bricked my Fire TV Stick 1 (bought at launch in Germany)...
Current situation:
- stick turns on, shows white amazon logo on black background
- continuously rebooting; ~5s black screen, ~5s amazon logo
After months not having it used, I found out I may be able to root it by now. So I did research over the vast amount of threads and posts and was overwhelmed by the information... So I tried to get started but struggled to find the right steps and therefore maybe failed.
I updated it to 5.0.5 (stock) and tried King Root, then Kingo Root, which was a success.
I tried to use the TWRP 3.0.0-7 v2 zip and used the sh command from the respective thread (I thought that was it, since all my devices before used either TWRP or CWM).
To this point, all went through and I wanted to reboot into recovery, but there was only this generic (stock?) red text recovery screen. I waited to be sure, nothing happened and I unplugged it to reboot.
It booted fine and I reflashed the TWRP zip, in case I didn't do it properly. Again it did as expected.
I then pushed the latest prerooted 5.2.0.1 zip and rebooted to recovery, but again this generic screen, so I unplugged it early, I think.
From there on, I got stuck at the white amazon logo, see above.
I did not unlock the bootloader, adb shell confirmed it not being unlocked before.
During bootloops, I did not manage to get any control via adb or fastboot.
So, is it bricked once and for all? If not, how can I save it?
I don't care about anything stored on it.
I also have a Y-USB-OTG cable and connected a keyboard before, but could not interfere yet.
(If bricked, would a Teensy be of any use? I have one from CCast rooting days)
Thanks for reading and in advance.
I had same problem with my fire stick when used the USB power of my TV.
Did you try to power the fire stick TV with the power point and USB adapter?

I guess you did not read enough.
At this point in time you can only root (kingoroot or kingroot) and replace root with SuperSu on a Firestick. TWRP (recovery) can not be installed because it was not released by rbox as of yet, that particular recovery\pre-rooted image is for firetv1 upgraded to OS5 and not for firestick.
Sorry man.
Have you tried to connect to a computer via USB and run kingoroot or kingroot for windows (whatever you used)? It is a small chance that will recover but it is a slim one....

I could not remember, so I just retried it with two different chargers and two different cables (both used to power my Nexus 5).
Unfortunately resulting in the very same loop... But thanks nonetheless.

Dang... Usually I don't make mistakes this dumb. Guess I learned my first lesson. I'll try to trace my mistake though, for future attempts.
I rooted it with the Kingo app, I think, and got that typical "stuck at 90%" and rebooted it like others did. It rebooted fine and Kingo verified it rooted.
I did not use Windows, I use Ubuntu, occasionally with Wine, yet I had no luck passing USB devices to it. (And always these missing libs...)
Normally, adb and fastboot (console) work fine (i.e. with my phone).
Now I have no chance to interfere with the bootloop, I think.
IIRC, sometimes I could spam commands and at one point adb was stuck at "waiting for device".
I tried to reproduce it just now, but could not get it again.
So, should I try adb or fastboot on another computer to be sure?
Would King(o) for Windows be of any help at this point? If so, what would be my best bet to catch it at some point I can recover it?
Is there any other way I could try? From my nooby perspective, could the bootsplash be an entrance for fastboot? Could it be just stuck trying to access erroneous partitions?
At this point I would try the most crazy and risky idea, since it is unusable anyway.
Thanks both of you for your answers.

Do you still have root? Is your stick responding to the su command?
If so read this post: http://forum.xda-developers.com/fire-tv/help/guidance-recovering-bootloop-firetv-t3446902
If not:
Try kingoroot for windows however it is a slim change in my opinion as you wrote a FireTv image to your FireStick.
Copy and paste from: http://forum.xda-developers.com/fire-tv/development/guide-fire-stick-replace-king-o-root-t3440923
"IF YOU RUN INTO SOFTBRICK ISSUE (stuck at fire tv logo)
Make sure you have ADB drivers properly installed in your windows pc/laptop.
connect a genuine usb lead to the firestick/pc.
download the windows version of KINGO ROOT and install it.
open KINGO ROOT on the pc with Fire Stick connected up to pc and tv.
wait for the button to pop up and click root.
if you dont see AFTV or get enable debugging in the KINGO ROOT program on pc/laptop please unplug the stick from usb and replug it back in.
if this still wont work restart the pc/laptop or try another pc/laptop.
you should after clicking root boot back up into your homescreen, if it doesnt boot back into your homescreen automatically, wait around 5 minutes and unplug usb and re-plug it again. "

Thanks for the links, but from what I see, I need to get past the bootloader splash for adb to work. I'm stuck at the white "amazon" splash, not the colored "FireTV Stick" splash after the amazon one.
Sorry for not making it clear (and for that amount of text that maybe hid it)...
From what I understand and recall, I did only flash the recovery, right? Or does it automatically flash the zip I pushed to internal storage?
And what confuses me, the first attempt booting into recovery AFTER flashing the wrong one I got the former mentioned screen with red text. Reboot worked and the Stick was running. So I did retry and got the same red text after rebooting to recovery. I assumed it did not flash again and unplugged it earlier than the first attempt. Since then it got stuck at the white bootsplash.
Since I am still a noob, it seems to me the system wasn't touched, maybe a faulty recovery integrity forcing the bootloader to loop.

I have no idea what you did however it will not automatically flash your zip, problem is you installed TRWP that was not meant for Firestick and overwrote its booting sequence. You most probably would had recover from your first attempt by re-installing a new image but once you tried to install it again it most probably finished writing the whole thing and damaged booting sequence.

Yeah, sad thing I got the wrong device, should have taken my time even more...
I googled the screen I got to two times before getting stuck:
http://forum.xda-developers.com/showpost.php?p=65968901&postcount=60
First time I waited approx. 15 minutes before pulling the plug to reboot. Since I noticed no difference I tried again and got the same screen. But this time I pulled the plug earlier, <1 minute.
I'd like to add that my bootloader was locked. Can I damage the booting sequence by corrupting the recovery or was my mistake that major to be able to do that?
I googled some key combinations to get into recovery or to bypass it, but I don't know if I get the right keys.
With my remote control I don't think I have enough time to hold the keys. Additionally I have a USB keyboard (Cherry KC1000; if possible, which keys btw?) and may be able to connect it via powered Y OTG cable.
So if anyone got any further input or ideas for me to rescue my FTVS, I'd be glad to receive it.
Thanks to all.
Anyone else maybe an idea?
The thing is, I cannot believe it is unsavable.
To summarize the current state (please see full details above):
- stuck in bootloop, white amazon logo
- flashed wrong recovery, after first flash the system booted, after second flash it got stuck (characteristics above)
- never flashed anything other than recovery
Strange thing it booted in first place, but now it refuses. Also I got the screen I mentioned above and unplugged as described above.
Can I possibly bypass the recovery check and try to boot directly to system? Or maybe interrupt for fastboot access?
If connected to PC, can you see it thru 'lsusb'? Or 'dmesg | tail'?

I tried both
watch -n 0.5 'dmesg | tail'
and
watch -n 0.5 'lsusb'
but with no identification whatsoever.
I double-checked with my Nexus 5 on the same port with the same cable, it identified fine.
One last bump for ideas before putting it into the trash.

Stock FireTV 1st generation - stuck in boot

Hi,
My stock fire tv is stuck in boot process. When I turn it on loads the b/w amazon logo and, about 30 seconds after, the colorful amazon fire tv logo comes up. And that's it, nothing else ever happens. No reboot, noloop, nothing else.
I have tried to factory reset it by pressing alt+i+print-screen hundred of times while booting with no success. I have tried with 4 different keyboard (including a logitech k400).
I have tried to connect a USB-A to USB-A cable from the fire tv and the PC and installed adb drivers (all devices are recognized by windows and display and device manager) but I can't detect the device with adb devices at any stage of the boot process at all.
Does anyone have any other possible way to un-brick it? O any other suggestion to revive it?
btw, It "bricked" itself. One day I turned on tv and I saw empty menus and nothing happened if I tried to navigate on it... So decided to reboot it and... there you go, the way it is now.
Thanks in advance.
Anybody can help please? I've got a precious brick os plastic and circuits on top my desk right now....

Accidentally flashed 7.2pro staging blob and boot.img to a 2017 16GB. Am I hooped?

No HDMI, no A/B on keyboard to boot into recovery, no light and APX in device manager.
Is it hard bricked or is there hope?
yes its bricked and no hope then RMA.
APX mode is nvidia recovery and currtnly no tool availble to public to unbrick, 2017 model,
If you are in China, I can try to help you.

If you get UART you might be able to load hekate from the switch and you can hack that up to restore emmc from someone else's shield
Thanks everyone for the response, but the unit was replaced so I'm back and running.

Philips 55PUS7909/12 is stucked in BootLoop

Hello everyone,
I have Philips 55PUS7909/12 and it is stucked on Philips Logo and after a few seconds, it restarts again with the Philips Logo. The TV is stucked in bootloop. I have already tried the Joypad Down key to enter into recovery mode but unfortunately it cannot enter into Recovery Mode. Tried with latest firmware in "upgrades" folder and also in root folder but no luck. Then I tried with USB A-A cable but "adb devices" returns nothing. I'm out of options. Can anybody help me to tackle this problem?
Thanks in advance
Hi
I have the same tv. Same things happened to it. Apearently that is the core level of problems. Which Tv brings itself to the Protection mode. You only see the philips logo. And tv shuts and opens up continuesly I guess. At this level tv doesnt allow you to use the joystick for Bootlader, dont worry about it. Also it may not allow you to see it as a device in adb. will tell you there is no device million times. I hope you find solution soon.

Have I bricked my FTV 4K stick beyond repair?

Sorry if this is posted in the wrong section, I am never quite sure where these sort of queries should go
To cut a long story short I unlocked and rooted 1 of my FTV 4K sticks, I was struggling with an issue on 1 and ended up installing a Magisk update. I know there are warning all over the forum about this please put it down to a lack of experience.
On reboot it just comes up with the black screen and the white amazon logo, it stays on this for about 2 minutes then restarts to the same black screen. i.e. its caught in a boot loop. It never gets to the white amazon screen.
I bought myself an OTG cable thinking this would get me to twrp so I could go into recovery and wipe it and start again or something, but even with the OTG cable plugged in it still does exactly the same thing. I have tried the same OTG cable and entertainment keyboard setup on another FTV 4K stick and it gives me the 5 second boot menu to get into recovery.
I am guessing I have killed it beyond repair? Is there anything else I can try to do?
Thanks
you need a usb keyboard and then you need to press a combination shown on youtube: , Don't be afraid it is very hard to do it but i can confirm it works 100% for sure!! The timing for holding the key press is all that matters to be successfully...
Try different timings if it's not working on the first run but you need then to hold the buttons for very long time until your fingers feel dead....
..im not sure if adb is working in "safe mode" you need to test that. If yes - you could use "adb reboot recovery".
2. you need to reflash Magisk in core mode.

You haven't killed your stick, install fastboot drivers and app.
Connect your stick to your pc via usb.
Enter
Code:
fastboot devices
when you see black screen with amazon logo, it should be inside fastboot mode
(If somehow you flashed update to boot.img as written in the guide)
If you see the stick in fastboot mode,
Pull twrp from kamakiri.zip
Place it in fastboot folder
Enter
Code:
fastboot flash boot boot.img
(boot.img or whatever the name of your twrp image)
Code:
fastboot reboot recovery
It should work, if not you can use shorting method again.
Thanks very much both, I will have a play around this evening when I get home from work and the kids are in bed, hopefully with the info above I can get back to recovery again.
Thanks for the help gents, in the end I had to do the shorting method to get the stick to do anything. It took about 6 attempts before kamakiri script even registered it as anything being plugged in, it just kept saying wait for boot.
Once it realised the stick was present and shorted I was away though, I have ended up having to factory reset and wipe everything so will need to start again with it but I am just pleased I don’t need to shell out again for a new stick.
Thanks again for your help
