Need to re-root 500gb shield tv after marshmallow update,
Says bootloader unlocked, shield is seen on laptop and adb devices but after reboot into bootloader the device isn't showing list of devices is blank, so I cannot install new image.? No yellow exclamation on drivers?
had the same problem in adb type fastboot devices and continue from there
Thanks Afgok
Thanks Afgok that's where I was going wrong,still had a few other problems but I'm back to being rooted again

Hi guys, need some insight here.
Did update for my 2017 shield tv today
and it got stuck at Android booting splash screen.
am not able to access fastboot with the controller connected to port next to the HDMI
and pressing A + B while connecting power.
while stuck at the splash screen, my laptop can see the device with "adb devices" but it is in unauthorized state.
how can I access fastboot?
Dear all,
I have an Nvidia Shield Tv 2015 16GB which i had rooted. But recently while trying to return to stock looks like i might have flashed wrong rom and it is completely bricked. It powers on but no display and can't detect in terminal when i type adb devices even though i have all the drivers installed. The Shield shows up as APX in device manager.
Is there anyway to recover this with any toolkits or any other methods please.
TIA
Harish
Hello guys,
My Nvidia shield 2015 (16GB) (not Pro) stopped working suddenly. GOT POWER but BLACK SCREEN.
Yesterday night, I turned off normally like everyday. This morning when I tried to turn ON using the remote, but no power. Unplugged the power cable and plugged back in. I see the power green light but black screen on TV. My shield 2015 is updated to the latest firmware v8.2.0 few months a go.
I want to boot the shield in Fastboot but the command ----> adb devices ---> cannot find my device, I installed the fastboot drivers and minimal fastboot & adb from here (also when I plug the shield to my PC Windows 10 - I see "APX" unknow devices (see attachment APX driver.PNG). I'm using the original nvidia micro usb cable.
[GUIDE] How to flash recovery image Nvidia Shield TV using FASTBOOT hardware method
All of the instructions I found for doing this weren't exactly clear, so I'm writing this out in a way that even dummies like me can understand. So, my Nvidia Shield TV got soft bricked when I tried to update my TWRP to this version. First, you...
forum.xda-developers.com
1) Install FASTBOOT DRIVERS: https://developer.nvidia.com/gameworksdownload#?search=SHIELD Family Windows USB
2) Install Minimal FASTBOOT & ADB: http://forum.xda-developers.com/showthread.php?t=2317790
Also tried the instruction to install the driver by selecting either from Nvidia sheild
- Tried SHIELD_Family_WHQL_USB_driver_201801 --> Select android_winusb.inf --> Tried "Android Bootloader Interface", "Android ADB Interface". See attached "Nvidia How_to_Install_Drivers.pdf"
Android BootloadervInterface" and "
- Tried Universal_Naked_Driver_0.73
- Tried adb-setup-1.4.3.exe
- Tried platform-tools_r30.0.5-windows
Not able to see my nvidia in adb devices.
I followed the proper instruction to put the nvidia in hardware fastboot, as follow: See attached "NVIDIA HowTo-Flash-Recovery-Image.pdf"
"Hardware Method:
- Disconnect power cable
- Connect power cable to SHIELD
- As soon as the green LED turns on -BUT NOT BEFORE- hold down the power button
- Count to three, then immediately release the power button
- You should now see the fastboot menu on the screen.
- If the standard boot process starts, disconnect the power cable and repeat
the process increasing the count in the previous step to 4.
NOTE: You should leave the HDMI TV connected to SHIELD at all times."
Absolutely the same problem here! nVidia SHIELD TV Pro (2015) worked fine about a month ago was turned off normally and wasn't used after that. Several days ago turned it on and nothing except green power light. Stuck in APX too.
Please help!
2020 edition and in the last month or so my 2020 Shield TV 4K HDR is also having issues with the screen blacking out at random times. Tried multiple refresh rates. Plenty of remote actions can restore it until the next random time it blacks out again, sometimes the next minute, sometimes hours later. Happened 6 times in one Youtube video and seemed to correspond with scene changes.
edit: of-course NOW that I post something here, I find search results everywhere.
The Hisense 4K ATV4 runs Android 9 Pie. I got into Developer Options and enabled ADB. Unfortunately, the bootoader isn't unlockable, but I think that you might be able to root it using KingoRoot, or even install apps from ADB.
Specs:
Storage: 4 GB
RAM: 1 GB
Processor: ARM Cortex A55
Same problem, my tv is not unlockable. It goes all black when i run "adb reboot bootloader", I can not find OEM
Unlock option under Developer Options!

Nope,I can not boot into fastboot mode! It only restarts the TV!
U can unlock it, my Hisense 43A6H is unlocked. After u get a usb male to male type a cable hook it up only 1 port communicates with the tv on my tv. Find out which one it is and it may require a reboot of the tv to get communication via adb initially then adb reboot bootloader then it reboots go to device manager install the bootloader interface driver for the device that shows up. Then run fastboot flashing unlock. That's as far as I have gotten, so do a fastboot reboot.
That's as far as I have gotten, I haven't been able to root it. I have the boot.img and i patched it with a lot of magisk versions and flashed to fastboot flash boot_b boot.img as fastboot flash boot boot.img & fastboot flash boot_a boot.img both basically brick the tv.
Before u continue call up Hisense and get your firmware and to recover rename the file from
usb_9612us_no_tvcertificate_user.pkg
to
usb_9612us_no_tvcertificate.pkg
Place the file only in the root of the fat32 flash drive unplug the tv and plug in the flash drive into ideally the port that communicates with the pc and hold power on the remote and plug in the tv... It will begin to recover the Hisense tv.

I've tried 7-8 times running "adb reboot bootloader" with different ports, It goes all black and in PC's device manager, there's nothing!
if you want root privileges you can try connecting to shell via UART, I've heard that you'll be directly provided with root privileges on some hisense tv!
@jerrydevis Hi thx for the reply yes adb reboot bootloader goes to a black screen, thats the bootloader interface of Hisense. Test out different USB ports for detection, use your headphones if needed and make sure u hear the ding. I had a hard time getting my tv to connect hundreds of times of testing until I got it down. On my tv there are 2x usb 2.0 ports, 1 of which communicates with the tv which is the one furthest from the screen in the back, not the one closest to the screen as they are stacked usb ports. If you need some pics to help, I can help.
I left the fastboot driver I have had tremendous success with. For general adb access use the adb-setup.1.4.3.exe to install the general google driver for adb composite interface or whatever its called... lol

Any way to get through this?
Edit: Done Successfully after restarting TV.
Great job buddy so did u unlock it?
Yes, I did
Great job. Hopefully @theydream has time to help us all out. Good luck all! theydream determined I & possibly we have A/B partition scheme i think is the right terminology. So I tried this command but no dice. I patched my boot.img with almost all magisk & even a modded magisk and all no dice.
fastboot flash boot_b boot.img

Hello. I have managed to unlock the Hisense U8G bootloader in the stupidest of ways. This will likely also work on the U6G, U7G, and U9G (Android TV models ONLY) since they run the same firmware. This will probably also work on every other Hisense Android TV.
So... tl;dr just run "fastboot flashing unlock" and that's it. No need to enable OEM Unlocking in Developer settings or anything since there is no FRP.
You will need:
A computer with adb and fastboot installed
Mediatek drivers if running Windows
udev rules if running Linux (available here: https://github.com/bkerler/mtkclient/tree/main/Setup/Linux)
Step-by-step on a stock TV OS (YOUR DATA WILL BE ERASED):
Enable Developer Settings by clicking on build number 7 times, standard stuff
Enable USB Debugging (this will also enable network debugging, but you will not need it)
That's all you need to do on the TV itself, settings-wise.
On the PC:
adb devices
On the TV:
Allow USB Debugging
On the PC:
adb reboot bootloader
fastboot flashing unlock
fastboot reboot
That's it. Your bootloader is now unlocked.
I am currently trying to figure out a way to dump boot.img and vbmeta.img and/or get into BROM mode so I can use mtkclient to dump boot.img and vbmeta.img. Help would be appreciated.
Hey. Do you know how to unlock bootloader of Hisense 50A71F, it goes all black when I run "adb reboot bootloader".

Thats normal, need a usb type a male to male plugged into 1 of the ports of your tv only 1 port gets detected and other not so ask me for the adb bootloader interface driver for the tv and ill provide, I have a Hisense 43A6H its a MEDIATEK MT9612 SoC which I unlocked the bootloader and cannot root it as I have all the drivers and boot.img and I patched it and typed command and on my tv and likely yours is the same command in slot B but it didn't root the tv...... Anyone know of an alternative method to patch and flash the boot.img? Mtkclient gui might work with python but idk haven't tried yet... Make sure to get the latest firmware from hisense so u can recover if u do something wrong or want to relock the bootloader.
To recover take your .pkg file which for me is update_no_tvcertificate_user.pkg and rename to update_no_tvcertificate.pkg and have only that file on your fat32 flash drive and unplug the tv plug in the flash drive and hold power button on remote pointing at tv and plug in the tv and it'll start recovering and u can let go of the power button.
Code:
fastboot flash boot_b boot.img
Don't freak out if you brick your tv make sure before u do anything to call up Hisense to get your firmware and they will email it to you. I bricked my tv like 3 times but recovered it and im talking to u now on my Hisense 43A6H Google TV Android 11 with a mini wireless keyboard mouse usb 2.4ghz dongle plugged into a usb hub by Sabrent with a 4tb hdd ntfs plugged in and a 400gb sd card fat32 it detects everything. I was gonna make a guide on how to do stuff on our tvs as well its tricky but fun when u succeed.
I've been having a hard time rooting the tv. Nothing takes, may someone help?

I would be thrilled if I could just get my Hisense to default to HDMI1 input upon startup, like you can with other SmartTVs.
Have a 65H6510G with a failed eMMC. Service port UART shows CPU trying to setup eMMC to retrieve data, fails and repeats. I can replace eMMC but need to flash in signed boot code. Any ideas?
