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.

Thats the stock Firmware. You must flash it with TWRP
Make a Full wipe and then Install the zip File.

I have TV Box CS918S ( Allwinner A31 CS918S 2GB/16GB 5MP ).
For the past few weeks I had problems with starting my TV Box.
It took ages to run first screen. Mostly what I can see it is logo with name MediaBox on me TV screen.
Right now my TV Box won't start and I can see only starting logo on TV.
I decided to upgrade frimware with original software.
I used PhoenixSuit 1.06 and select recovery mode.
But on a recovery screen I wasn't able to select any available options.
My remote didn't working in recovery mode. Selecting 2 button on my remote I rebooted my TV Box. Without any results.
I decided to use ADB SHELL. Commend line on my laptop. I was able to connetc and see everything on my TV Box.
I did wipe cache but nothing big happend. TV Box still not starting but I can connect with laptop and PhoenixSuit or ADB SHELL.
I did adb reboot bootloader and I think it was not a good idea. I got stuck on first screen with MBOX logo on it.
Right now I can't connect my TV Box to the laptop and PhoenixSuit and ADB SHELL.
Any idea what I can do to wake up my TV Box ? Maybe there is a hardware reset of CS918S ?
Hello everybody,
I bought the SCISHION V88 Piano TV Box - RK3328 4GB RAM + 16GB ROM Android 7.1, and I made the mistake (without knowing the results) to install the SuperSU app from google play (the box is rooted, but do not ever install the SuperSU).
The result is that after rebooting my box (asked by the SuperSU app), it stucks on the Android Logo but factory recovery is still accessible when pressing the reset button.
I managed to do a factory reset via factory recovery without success, still stuck on boot on the Android Logo.
I managed to fix it by installing the firmware uploaded by changonc in freaktab.com.
You can find the firmware from his post.
http://freaktab.com/forum/tv-player-support/rockchip-based-tv-players/rk3328-devices/681869-scishion-v88-piano-tv-box-rk3328-4gb-ram-16gb-rom-android-7-1-usb-3-0-fast-lan?p=705933#post705933
The tools that I have used are RockChip_Batch_Tool_v1.8 and DriverAssitant_v4.4 in windows 10 x64.
I installed the DriverAssistant_v4.4
Then executed the RockChip_Batch_Tool_v1.8
Loaded the firmware bin file downloaded from changonc's post
rk3328_7.1_box_RX4_SSV6051P_tongwang_RKMC-update_20171228.bin
Then connected the box with a usb cable Male A to Male A, on the box's usb port which is located close to the piano keys (it is the one on the edge and not the blue)
The moment that it connects with the usb it switches on.
Immediately I pressed the reset button and keep it pressed until the box 1 in RockChip Batch Tool turned yellow.
Then I pressed the upgrade button.
The procedure started, and the first time it ended with an error.
Then I repeated the same procedure and it finished successfully.
After* I disconnected it and connected it to the TV, and it started loading.
Be very patient when on the Android boot logo, it can take about 10-15 mins to load the android the first time.
hi, thanks for the writeup. After installing this new firmware, what is the 'Android Patch Level' and kernel build date? You can find it from settings->About Phone
http://www.scishiontvbox.com/firmware-for-scishion-v88-piano-tv-box shows that there is a updated firmware available, but there is no link provided to download it.
Thank you. Today i followed the steps you have given above and updated my v88 piano tv box.
This scishion v88 piano tv box is a wonderful device with 4G RAM, but the stock ROM running this box is not great. They have removed some essential components and it is impossible to get an alternate launcher or other components to work on this.
i wonder if there is a custom android ROM for this device.

Hey All,
My Amazon Firetv Stick no longer works, All I get on the screen is a flashing Firetv logo that reboots the device in a loop sequence, I am unable to enter the main firestick operating system, The factory reset from the remote does not work I am unable to access the MENU.
Amazon refuses to replace the device since I am out of warranty, I can't seem to find any guide out there on how to unbrick the device and restore it, I was using the default ROM stock that came with the device.
Any help would be appreciated.
Whats the device code number at the bottom side of the stick?
I messed up my TV soft resets not bringing the screen back.
I set Secondary Display to 4k and it black screened now stuck in reboot mode.
It starts up and after Android tv logo it reboots a couple times then just suts black screened
There is not manual reset button.
Is there a recovery file that i can load onto a USB drive and use the Physical power button to boot the usb drive and recovery my tv or is it jacked?
Figured it out flashed to v662

where did you find firmware, could you share with me?
I think I got same model: 55S434
current version: v8-r851t02-lf1v458.018656
I am facing frame drop on 4k-60 fps, youtube or any other software so I think there may be bug with my version so I would like to rollback on some stable version.
Did you ever find this V662 firmware that works for the S434?

This site is more dev less how to i assume most members figure if you are not smart enough to read the forums and search it and figure it out on your own you have no business flashing your devices.
Notice no one responded to my ask for help i just figured it all out on my own in about 6 hours of research and then got a thumbs up.
REMEMBER you can brick your devices

Awesome! Thank you so much for the reply! I found the telegram channel and obtained the update zip. TCL support wouldn't provide the steps to update, so thanks so much for the info! I actually accidentally hit the Netflix button which strangely got me out of the boot loop so I didn't have to restore after all. So glad it's working now!
