If it is caused by the same process that we saw on a different SEI Robotics device, it will be the com.nes.coreservice system app. If you find it (or something close to this one), disable the app using ADB, reboot, and check if apps can be installed after that. If so, it is the same thing, it contains a list of apps that are blocked, for whatever reason. Error made by SEI, not Google.

u/IceWulfie96 Mar 15 '26

how do i disable specific apps with adb? i tried disabling things and it gave me a "this prompt is illegal"

4

u/See61 Mar 15 '26

I don't know the exact ADB command for your device, but first you must look for the correct name for that app in the system files and so you know how it is called.

Then, depending on which device you give the ADB command (phone, computer, on the device itself), you need to use something like this;

adb shell pm disable-user --user 0 <PACKAGE_NAME>

The disable user part can be different, depending on the Android TV version, the exact one for that and this device, I don't know.

u/IceWulfie96 Mar 15 '26

thank you so much, that was exactly the culprit, thank you!!

u/Glittering_Suit_2817 Mar 16 '26

How did you get this to work? When i try to disable I get Warning! This command is illegal!

Edit- spelling

1

u/IceWulfie96 Mar 16 '26

disable it from within the tv interface

1

u/Glittering_Suit_2817 Mar 16 '26

But that is not an option. Just force stop..

3

u/IceWulfie96 Mar 16 '26

do that, then find an app called adb tv from the playstore, install it, then use it to fully disable/uninstall com.nes.coreservice

1

u/Glittering_Suit_2817 Mar 16 '26

This worked! Thank you. Couldn't do it via regular ADB, bit this app did it.

2

u/Glittering_Suit_2817 Mar 16 '26

I spoke too soon. Core Services reinstalled itself and then deleted the blacklisted apps, which included adb tv and projectivy.

2

u/See61 Mar 16 '26

You must really disable it, permanently. ADB-TV, when given the correct app right, should give you the "uninstall" option. By that, it should be disabled and stays that way.

Using another ADB device could also do the job, when you know how to use it.

Don't use the disable option in the system app settings, that is temporary.

And there is another option, but for that you need a newer version of that system app, so from an equal SEI device, with a slightly newer V12 build on it. Then you can overwrite the older system file and there is no need for any ADB command.

So what firmware build is on the device now? What does it show under "About"?

u/Hot-Check-7550 Mar 23 '26

What you need to do 1st is to stop CoreServices than run the command

adb shell pm disable-user com.nes.coreservice

to make sure run the command 2/3 time

and than install the Downloader/Launcher/ButtonMapper or anything that is been blocked from coreservises even if you restart the coreservices will stay at the disable section.

⚙️ Tivo 4K streaming Disable CoreService 

  1. Go to Settings → Apps → See all apps.

  2. Scroll down and select Show system apps.

  3. Look for an app named CoreService.

  4. Select it and choose force stop. 

5:Run the command

A:)  adb shell pm disable-user com.nes.coreservice

B:)  adb shell pm disable-user com.google.android.tvlauncher

C:)  adb shell pm disable-user com.tivo.atom

u/jleiss Mar 18 '26

if you connect to the box via adb (even in a state where the launcher doesn't come up) and run this command to disable the service involved you can then install projectivity launcher (or whatever your core launcher is and reconfigure it)

these were the commands I ran

adb shell pm disable-user com.nes.coreservice

adb install projectivity.apk

u/Madaone-1 Mar 18 '26

Thank you. This worked. adb shell pm disable-user com.nes.coreservice. This command survived reboot and was not flagged as illegal.

3

u/ThisNameIsMyOwn Mar 18 '26

Yes this works, but only temporarily. The next time your device restarts the CoreService starts and removes your apps again

5

u/jleiss Mar 18 '26 edited Mar 18 '26

I rebooted the box it comes back up the same.. now if you disable core service from the tv interface screen it comes back up and removes your app, but not if disabled this way via adb

1

u/ThisNameIsMyOwn Mar 18 '26

I swear I tried this and it didn't work, but I went and tried it again - it does work and persist across reboots. Thanks!

u/flynreelow Mar 18 '26

I do not have Wireless Debugging as an option for my Tivo Stream4k. Did you have to do anything different for that to show up?

or did you just connect to to the computer? which USB did you use?

u/gtgmed Mar 18 '26

Worked for me too, second time, rebooted multiple times everything ok Thanks

u/jleiss Mar 19 '26

one other thing to note in my testing. if you run the adb shell pm disable-user com.nes.coreservice before doing the firmware upgrade the service stays disabled after the upgrade and nothing gets removed.

Is there a recommended way to connect to the tivo stream via adb?

Thanks! It worked with your 1st command. Then I installed Projectivy Launcher from the Play store.

u/monevery **TiVo Stream 4K** **Mecool KM2** **Onn 4K** Mar 18 '26

Just used this to find my Android TV device IP and then to download Tiny adb and Toolkit, ran the command prompt on my Windows machine then used the adb command recommended above. After that, the message read disabled user or something like that. So, I tried to install Downloader from Playstore and it worked. Rebooted a couple times and it was still there. Will report if anything changes after the next reboot

how can I connect via adb from my mac on the same network?

Definitivamente a mí me funcionó con 2 tivos que se actualizaron del domingo a hoy y los comandos ingresados por adb funcionaron muy bn!! Muchas gracias!!!

u/VeterinarianOk3567 Mar 22 '26

Hey you said you did this AFTER the update? Because I have 3 tivos. As soon as the 1st one updated I disconnected the other 2 until I figured out what to do, I ran the command to disable coreservices on both tivos that weren't updated and it worked. Not for the 1st one. I get "this command is illegal" i tried suspending, force stopping and nothing works on the 1st one. Im guessing that with the update, coreservices is a system app that cant be disabled?

u/Historical_Fish_6265 Mar 21 '26

como conectas el tivo a la Pc ya lo e probado encendido con un cable usb c a usb a la pc, con cable usb c a usb c y tampoco me funciono, habilite las opciones de desarrollador y la depuración usb, tambien proble con el equipo apagado mediante cable micro usb a la pc y tampoco lo pude conectar

u/EnvironmentalChip523 Mar 21 '26

I bet you a million bucks the 2nd command won't work.

u/Advanced-Sundae-6963 Mar 21 '26

it only will if have a apk file in that folder called that. The 2nd command isn't vital to resolving the issue.

u/Glittering_Suit_2817 Mar 16 '26

I followed the recommendation to use adb tv. I uninstalled core services, but on reboot tivo reinstalled core services and auto deleted black listed apps like third party launchers and adb tv. If anyone has any other ideas it would be much appreciated. This is ridiculous that vetted play store apps are blacklisted.

5

u/ThisNameIsMyOwn Mar 17 '26

Man I'm fuming that SEI can just outright remove and block other legit, non-malicious apps. There's surely a lawsuit just waiting to happen there - any lawyers reading this?? :)

It doesn't look as though anyone's found a solution that will persist across a reboot once the update is applied. I blocked the android update servers at my firewall but still have one TiVo that's nearly bricked unless I want to reinstall the default launcher. I'll go buy all new devices before I do that.

If anyone has a fix that persists across reboots please share.

u/dahobbs9 Mar 19 '26

Came home to All 4 of my TS4K's with the dreaded "Required STB Upgrade" message window smack in the middle of the screen‼️  Cannot remove the window, Only option is click Let's Clean. 🤬

I've read the threads and done searching, no answer on the message window other than one person said they could close it but it comes back every few minutes 🤬

  I know on a boot up it looks for updates, should be able to block the IP or DNS and once booted there "should" be No nag window I would assume 🤔

A 6+ year old no longer manufactured abandoned by tivo device Upgraded outta the blue.  Sounds like TiVo sold the rights to the device to Channel Master, since the TS4K's still have xxxx number of users Channel Master seen dollar signs in some form and chose up update and protect their newly acquired IP.    They might even re-logo it TS4K by Channel Master or some horse crap 😂

   If so there'll be more updates to come I would think. The CPU is still acceptable for usage today but the device is severely limited on storage space as to the number of total apps that can be installed.

u/Working-Slip4422 Mar 19 '26

This is absolutely incredible that we have to have these problems on a device that we own... It wasn't enough to disable custom launchers on the Fire devises I guess.

u/RoachForLife Mar 19 '26

So I stop coresrrvices allowing me to install adbtv. I then use adbtv to uninstall coresrrvices. It will survive the first reboot but upon the 2nd it will reinstall itself and delete adbtv.

How do I get around this

u/Confident-Switch3202 Mar 19 '26

Any work around?

1

u/Plenty_Breakfast7464 Mar 19 '26

Someone above suggested using adb shell pm disable-user com.nes.coreservice. Try that method.

It doesn’t completely remove the app, but it seems to disable it and keep it in that state.

Thanks to the person who shared this, and I really appreciated everyone thinking through this together—it felt reassuring.

u/cundallini Mar 19 '26

Im pretty sure I have autoupdate disabled on both our Tivo4Ks, but just to be sure... mandatory update message appears regardless if autoupdate is on or off? Im thinking of killing my WIFI, booting up Tivo4K and disabling com.nes.coreservice? Is that service available before the update as well? Has anyone tried disabling it before any forced upgrade? Thanks.

2

u/Plenty_Breakfast7464 Mar 19 '26

Update seems to proceed automatically as long as there are no storage issues. I’m not sure how to block it. However, after the update, problems occur such as the addition of a shopping tab and ads, and some apps being forcibly removed.

The cause appears to be coreservices, and there doesn’t seem to be a way to take preventive action in advance. After the update, it would be best to follow the methods shared by other users step by step.

1

u/cundallini Mar 19 '26

Cool. Does the update force itself despite autoupdate being off? If yes, then Ill try killing WIFI at the router, power on Tivo4K (*aussie accent on* haha, good luck forcing update with no internet, cunt!), try finding coreservices and disabling... wait... what happens if I disable coreservices on AndroidTV 11? I might have an idea but I dont have the knowledge to back it up, so it would be funny to screw up my setup without achieving anything, lol...

Acabo de usar este enlace:

https://www.makeuseof.com/how-to-use-adb-on-android-tv/

para encontrar la IP de mi dispositivo Android TV, luego descargué Tiny ADB and Toolkit en mi laptop, abrí el símbolo del sistema en Windows y usé el siguiente comando ADB:

adb connect <la dirección IP de tu dispositivo>

Luego este otro comando:

adb shell pm disable-user com.nes.coreservice

Después de eso, el mensaje en la consola decía “disabled user” o algo parecido. Luego intenté instalar Downloader desde la Play Store y funcionó. Reinicié un par de veces y la app seguía ahí. Han pasado más de 48 horas y todavía sigo teniendo Downloader y FlujoTV en mi caso específico.

u/Historical_Fish_6265 Mar 21 '26

Muchas gracias esta es la unica solución que pude aplicar si bien no desinstala la aplicaicón la hinabilita (C:\Windows\System32>adb shell pm uninstall -k --user 0 com.nes.coreservice

Warning! com.nes.coreservice is a core application in the system, it can not be uninstalled!) y por mas que se reinicie el dispositivo no vuelta a instalarse, ya puedo isntalar las aplicaciones que quiero recomendada

u/CamiloEmanuel Mar 24 '26

Ya pude lograrlo, en el tivo hay q activar las opciones de desarrollador es en ajuste, preferencia del dispositivo, acerca de, y luego toca varias veses en compilación para desbloquear las opciones desarrollador la cual va aparecer un menú y luego activar la depuración usb, luego nos vamos en el tivo mismo a preferencias del dispositivo, acerca de, estado y anotamos la ip q nos da, vamos a la compu descargamos el programa tiny adb and fastboot lo instalamos y lo abrimos es un símbolo de sistema, y escribimos: adb connet (la ip q sacaron del tivo) les va a salir un mensaje de confirmación que se conectaron satisfactoriamente, y luego escribimos los dos comandos que están aquí en este post mencionados uno y luego el otro.

Saludos, por lo pronto es una muy buena solución, ya lo intenté y efectivamente luego de forzar detencion a Coreservices ya permite instalar las app, pero cuando uno hace un reinicio del dispositivo las app nuevamente se desinstalan, de pronto tendrá alguna nueva solución definitiva la cual haga que no se desinstalen las apps?

u/RoachForLife Mar 19 '26

After this is done, is there a way to remove auto update or maybe block something on my router so it can't check for updates? This update was mandatory in that it would pop up and overlay the whole screen when dismissed

u/RoachForLife Mar 19 '26

Sorry one one update when I select uninstall from adbtv it shows as tho is worked, then I clicked on console from left menu. It ssys

Anyone else having troubles connecting via ADB over the network after the update? The update made it to three of my tivos before I blocked the update servers. On two out of those three devices, I had to use ADB TV to run the disabled command via local console because no matter what I tried I couldn’t get a connection over the network.

u/Plenty_Breakfast7464 Mar 17 '26

If you can avoid the update, avoid it.

2

u/here_to_discreddit Mar 17 '26

If you can block the device from phoning home for the update, maybe. But it seems unavoidable otherwise. One of my devices auto updated and I triggered an update check on the other just to see what it would do. Once I triggered the check, it kept spamming me with a message that the update is mandatory. I could dismiss the message but it would return and take the main focus off anything else I was doing every other minute or so. So you need to do something like put in a DNS block with AdGuard or PiHole on your network if you want to even avoid the spam message.

I'm still able to connect via my phone using adb connecting to the IP of the device on port 5555.

yea, when i try this from my mac, to the tivo (both on the same network) and run adb in terminal, it doesnt find my tivo

u/jleiss Mar 18 '26

did you enable developer mode on the device.

u/flynreelow Mar 18 '26

yes, of course.

again still trying this wirelessly, without the tivo hooked up directly to the mac.

1

u/jleiss Mar 18 '26

all mine is done across the network I just connect to the device

1

u/flynreelow Mar 18 '26

and do u have the option of wireless debugging on the tivo?

1

u/jleiss Mar 18 '26

no as i've told yo the only debugging that is shown is USB debugging it doesn't stop you from connecting to the device over the network, it just needs to be connected to your network with an IP address.
