Hi.
I have the latest original firmware on my SM-T530 and screen mirroring does not work at all. I´ve tried two different methods:
1. Mirror the screen to a Amazon Fire TV Stick. The SM-T530 finds the Fire TV Stick, but a few seconds after I connect the devices, the Fire TV Stick says that the mirroring has been stopped (I can never see the screen of the SM-530 on the stick).
2. Using Screen Stream Mirroring App. I've also tried to mirror the screen bei using my Enigma2 Set Top Box. The mirror is available throgh rtsp. But the TV-Screen stays black.
Other devices (Honor 7, Ascend P6 Omni Rom, S3 Mini CM 11) work perfectly with both methods so I guess it's a problem with the SM-T530 firmware.
Is this a known issue of the firmware?
If not, could someone be so kind and test the screen mirroring with a Fire TV Stick?
If I'm the only one with this Problem, is it possible that I've unistalled a service (app) that is needet for screen mirroring? I've used Kingroot and uninstalled some Samsung and Google Stuff... So if It works on other SM-T530-Devices, I would flash the stock rom again but I don't want to do this if doesn't work anyway... If somebody else confirms this problem, I would contact the Samsung Customer Service.
Thank you for your help!
I´ve switched to DU. Will not flash stock firmware again so the Bug doesn´t matter anymore for me.
Managed to brick my shield somehow. I'm still able to enter the bootloader, but other than the nvidia logo keeps looping. The thing is I don't know if I flashed the right developer os. I choose the one which said 2015 Developer Pro because I've read the 2017 pro is the excactly same as the 2015 pro, is this true? I used the nvidia controller's usb a/micro-b cable, which I think isn't enough as it gave me a lot of errors at the start but then worked until i flashed the system img which stopped at step 7. I'll order order another a/a cable instead and try, as I've read through the forum and found that the cable can be the issue, but maybe someone can enlighten me more. Thanks in advance!
So I got it working again, to answer my own questions for you.
1. The 2015 pro (500gb) and the 2017 pro (500gb) uses the same images.
2. The cable wasn't the issue, I think the Shields usb ports have been worn out (seems to be an issue others have experienced aswell) hence the random disconnects while flashing.
Solution:
I managed to boot into twrp without losing usb connection (fastboot boot twrp.img), and from there I flashed the developer os.
I have an Android TV and I wanted to disable its launcher. Because I wanted to install my own launcher !
So I connected to it via ADB and made some changes.
Then the TV software crashed and when I restart the TV, I just see the first welcome screen of TV and nothing happens after that.
I think I need to factory reset the TV and I have nothing to do that.
My TV brand is UNEVA.
Does any body know nothing about that ?

On my fire tv edition I had to hold the power button a few second with the tv turned off and a few second after the logo starts up. The physical power button on the tv. You can try on the remote too, the same way. This is how you get to tv recovery on a fire tv edition.
Actually I didn't understand what to do !
Could you please write the steps again by detail ?
thank you
Do you have an android tv or a smart tv? Is it a streaming device or the tv itself is not working? Turn off tv, hold down power button while you plug the tv back on and wait for a start up screen then the recovery screen.
Yes I have and Android TV.
It was working correctly , but after some changes in firmware files using ADB, it has been stuck in startup screen.
Because of that I needed to go into recovery mode.
I followed up your instructions, but nothing happened.
My TV brand is UNEVA. It is a Chinese brand and it is not famous at all.
But its firmware name is "Wisdom Share" which is a bit famous.

You should be able to find the stock images for the current Android operating system on Google's website and then you can just reflash those
Your uneva brand Tv is an Android tv, and I assumed you connect to adb remotely. Can you check if you can still connect to adb? If you are messing with adb then you should know recovery mode, you need to get into recovery to factory reset.
Yes UNEVA is an Android TV and I used to connect to it using adb , but after making some changes in OS files (in shell mode) , the TV damaged and now I just can ping the TV and can not connect to it using adb.
So finally I think I need to get into factory reset mode.
But the problem is that I don't know where is factory reset page?
watch this video, it is how i factory reset my tv when i couldnt get pass the tv logo. www.youtube.com/watch?v=g-kdQjSE__A
I watch the video.
I did this bust it didn't work and my TV does not turn ON !
It means that my TV is different from the Toshiba model in YouTube video
every brand of tv have their own hard factory reset buttons to press when you cannot access the software of the tv. you have a tv i have never heard of maybe you can get a hold of pdf of your tv instructions. Good luck.
Unfortunately I could not find its Guide Book. It is almost a no-name Chinese brand and because of that, I thought maybe I can find a way using the TV's android software (Wisdom Share)
But anyway, thank you for your help.
I still have to search for a way and would be thankful if anyone can help.
I have an nvidia shield tv pro 2015 which I have tried if I could downgrade from android 11 to android 9. then there could be black screen on it now and I can well turn it off. Nothing happens if I turn it back on it shows just black screen. i can hear it when i put it to computer and if I run adb then it writes list of devices attached ................
I was sorta in the same predicament a few days ago and managed to get mine going after unsuccessfully flashed 8.0.1 which couldn't pass the nvidia loading screen. From this website Here I downloaded the NVIDIA SHIELD ANDROID TV Pro (500GB version) OS version 8.2.3 which is Android OS 9. Good luck!!!
