First, make sure you enable debugging from the "Settings -> About Watch" menu on the watch. If you don't see the option, first go to "Settings -> About Watch -> Software" and tap 7 times on Software Version to enable developer mode. Then go back and enable debugging from "Settings -> About Watch". You can connect either through direct WiFi from your PC to the Watch, or you can connect your Android Phone via USB to the PC with the watch connected via Bluetooth to the Phone. The easiest way to set this up is to install Galaxy Watch Designer, and follow the instructions for connecting to the Watch. Just leave Galaxy Watch Designer running while the watch connection is established and Tizen Studio (and Tizen Tools for Visual Studio) will be able to function with your watch.

Note on Phone USB option... Make sure you have USB Debugging enabled on your phone. I've found that I need to restart my watch after I disconnect the phone from the PC if I want to connect again later on. It looks like the ports hang and don't get released properly after a connection is established. If you don't want to run GWD every time, the below commands work for me when I plug my phone to the PC.
sdb start-server
sdb forward tcp:7135 tcp:7135
sdb connect 127.0.0.1:7135

Yes, to install apps you need to have a Samsung certificate. GWD will create one for it's own uses when you have the watch connected. If you want to use Tizen Studio to deploy apps you create, you can create a Samsung certificate using the Certificate Manager tool in Tizen Studio. Make sure you have installed the Samsung Certificate Extension SDK from the Package Manager tool to do this.
You should be able to ignore the sdb version error.

I just want to use sdb command for installing apps.
sdb install xxxxxxxc.wgt
That isn't my own.
I really need tizen studio ?

As far as I know, it's not possible to install an unsigned wgt file on the Galaxy Watch. I've only been able to install via sdb apps that I have written myself on Tizen Studio. Hopefully someone else reading this thread can offer more help.

Hi there! I wanted to change a region on my Galaxy Watch, but there are some issues.
sdb connect "my watch ip" - error: target offline
To connect via bluetooth
failed to connect to 127.0.0.1:7135
Debugging mode are both activated on my watch and pone. Nothing works...

Maybe look into this post.

SM-R800: Change CSC for Samsung Pay

Hello,
I was not able to follow the instructions to change CSC only because I am not able to get sdb to connect to my watch.
A Galaxy Watch, SM-R800, German version that I would like to switch to French (XEF) to activate Samsung Pay.
I only tried over WiFi. Watch and both computers I tried were connected on the same network.
Each time I manage to get the watch seen in SDB but I always get an unauthorized (and no popup on the watch) so I was not able to run an sdb shell.
I followed the instructions there: https://forum.xda-developers.com/showpost.php?p=79537836&postcount=4
so SDBstarterKidv1 containing sdb, watch connected to my WiFi, debugging activated. I shut down the watch, the start it again, then sdb connect IP (IP obtain from my router)
The watch itself it identified, but I always get the unauthorized issue and I have no idea how to solve it ?
It there any other option ? Or what could I do to have it connected to sdb.
I tried with a tablet running windows 10 home 32 bits, a desktop pc running windows 10 pro 64 bits, and I tried with sdb from SDBstarterKidv1 and sdb from latest tizen sdk, and I always had the same errors :'(
One UI 1.0
Tizen 4.0.0.4
R800XXU1CSG4

I've just managed to change mine so it is possible.
Make sure wifi channel is set lower than 10?, and also try running command prompt in admin mode.
Sent from my SM-N975F using Tapatalk

It is not required to execute the commands from Admin authority.
But one thing I noticed is that if the watch is not active, RSA key is not generated and connection is not made. So I set my watch's display setting to keep it on for 5 minutes, and after that I am able to connect via sdb.
On an unrelated note, I have started to notice that since last update of Samsung pay on watch, my card is getting delined at POS. In the watch, the payment is shown as succesful, but in POS machine, it is rather declined.
I changed my CSC from USA to Singapore, and still the issue retains. Anyone else facing the same issue?

FIX YOUR APP SYNC! Smartwatch 3 is not dead yet!

OK guys your watch will still work with many Wear OS apps but apps won't sync up with your phone any more. The problem is that the version of Google Play Services on your watch is way out of date.
The solution is you need to sideload a newer version of google play services and then like magic all your apps that can still work with Wear OS 1.5 will work again.
You need to download and install adb fastboot on your PC, and the USB drivers for your particular model of phone. Then go to apkmirror and download the latest version of "Google Play Services (Wear OS)" as an APK.
Now put your Smartwatch into developer mode by going to settings --> about --> build number (click it 7 times, congrats you are now a developer)
Now go to Settings --> Developer Options --> ADB Debugging (enable) and Bluetooth debugging (enable)
Back on your phone, Wear OS App --> Advanced Settings --> Debugging over bluetooth (enable)
Enable Developer options on your phone as well through settings --> About --> Software info --> Build number seven times. Enable USB debugging.
Plug phone into PC with usb and open a command prompt in the directory where you've installed the adb files
Code:
ADB devices
should show your phone unauthorized. Authorize it on the phone popup prompt. Now the command should show your phone as "device"
Code:
adb forward tcp:6666 localabstract:/adb-hub
adb connect localhost:6666
On your watch, authorize the connection
On your phone, Wear OS app, Advanced settings, you should see Host: connected and Target:connected
If you get into trouble, run
Code:
adb kill-server
and try again.
Now you can install the apk
Code:
adb -e install -r (path to apk)
it will take a long while and may appear to hang. Give it time, at least 15 minutes. Go do something else. Wait for the command prompt to come back.
Now reboot your watch and revel in the magic as your apps suddenly reappear.
You also try sideloading other apps your mileage may vary. On APK mirror you can sometimes find older verions of Wear OS apps, look for ones that require Android 6.0+ Instead of 7.1.+

FYI I've tried sideloading several apps, and while many don't work properly, I was able to get Maps working by sideloading
com.google.android.apps.maps_10.35.2-1035250000_minAPI23(nodpi)_apkmirror.com.apk

Hi,
Thanks for this =)
Is there a reason to push the app through the phone instead of directly to watch?
EDIT: just do the same but directly connect the watch through USB worked well for me, including installing more apps like GMaps and Messages.
EDIT2: Just did this, so people could find this workaround faster =) https://support.google.com/wearos/thread/55427445

Unfortunately, I don't use an account by Google. Would you mind quoting your solution here?

Hey first of all, thank you to bring me a light to follow,
I can confirm that if you use usb is more quickly, just I have:
1: installed "15 seconnds adb installer v1.4.3" found on this forum
2: Plug my smartwatch 3 on my pc (windows 10)
3: downloaded the most recent google play services (wear os) from apk mirror
4: rename the downloaded apk with a shorter name
5: placed the apk on C: and then open a power shell window in that location (****f+right click)
6: put this command adb install -r -g aplicationname.apk
7: wait 5 minutes
8: enjoy

Hi people,
I own a sony smartwatch 3, got some problems about sync multiple times. I always found simples workarounds but some days ago, Google dropped support for wear 1.5 devices.
I consider this as an official announcement:
https://support.google.com/wearos/thread/5538033?hl=en
Therefore, we have a "workaround" for those that need more time to buy another smartwatch or else.
Inspired from this: https://forum.xda-developers.com/smartwatch/smartwatch-3/fix-app-sync-smartwatch-3-dead-t4121409
# Download the latest GService for Wear OS
Using apkmirror website you can find the latest apk for "Google Play Services (Wear OS)",
This link will give you the page of GService v20.21.17 which is the latest available on 2020-06-25.
You must ensure 2 things:
- Is it the latest version
- Is it compatible with Android 6.0+ (as it's the wear android version, 7.0+ and above will not work)
You can also download other apks to install, see the "More" section at the bottom of this post.
Soon or later, Google will definitely drop android 6.0. When this will happen, the latest version will not be available anymore for android 6.0+, therefore it will be the end.
# Download/Install adb debugging tools on your computer
There are multiple ways to install the adb debugging tool, I recommend following the steps you'll find on XDA website: https://www.xda-developers.com/install-adb-windows-macos-linux/
Available for Windows, Linux, and macOS.
# Enable ADB Debugging options on your watch
Enable developer mode by going to
Settings --> about --> build number (click it 7 times, congrats you are now a developer)
Now go to Settings --> Developer Options --> ADB Debugging (enable)
Then open and keep the command line window (aka "terminal")
# Connect your watch to your computer
Then using the terminal, type "adb devices", after a moment, you should get a prompt asking for debugging permission on your watch: accept.
In the terminal, you should now see something like "14452D11F536B52 device" when typing "adb devices" again.
If you see "unauthorized" or else, you're not ready for the next step, go back and try again.
If you struggle at this step, you may need specific drivers or else for your watch, google will be your best friend at this point.
# Send the app to your watch
In the terminal, type "adb install -r path_to_the_apk_file", replace path_to_the_apk_file by the path to the file you download from apkmirror earlier.
Then wait, the installation can take several minutes. Once it's done, restart your watch and you should see the apps beginning to synchronize themself =)
----
If you're new to the command-line tool (aka "terminal"), I'll assume you're a window user.
So you may need to type something like "adb install -r C:/Users/Robert/Downloads/file_downloaded.apk", again, you'll have to replace Robert by your windows username and file_downloaded.apk by the name of the file you downloaded earlier.
The best way to get this line right: open the file explorer, click "This computer" in the sidebar, then click on your main hard drive, then the folder "Users". Here you should see a folder with your username, click on it, then go through folders & files until you see the downloaded file. Once it's done, you should be able to get the full pathname by click in the explorer address bar (didn't understand ? See https://winaero.com/blog/show-full-path-address-bar-windows-10-file-explorer/ ) then at this point you should know how to execute the last command by reading again the last step "Send the app to your watch"
----
# More
You can follow this step and install any apk you want, but I don't recommend installing apk not made for Wear OS even if it works
More apps installable this way on your watch if you don't want to wait for app sync:
- Google Messages (SMS), latest is v6.1.095 on 2020-06-25
- Google Maps, latest is v10.35.2 (android 6.0+) on 2020-06-25
The GMaps is a good example about obsolete versions: on 2020-06-25, the real latest available is v10.43.2, but it's android 7.0+ only, so don't expect GMaps to work indefinitely for your watch, it will stop working soon or later.
# Say thanks
Please, if you can click upvote or post an answer: it will help people with the same problem find this

Thanks for posting a simplified process.
I only used Bluetooth because I have other Wear OS watches that don't work over cable connect, so it's the way I am familiar with. I like to use different watches depending upon activity and mood. The Smartwatch 3 is a great watch for outdoor activities because it is sleek, waterproof, and very sunlight visible.

You saved my watch!

Hi. In the link to install the adb debugging tool, I can only get as far step 6 connecting my phone. When i type 'adb devices' in the command prompt it says -
* daemon not running; starting now at tcp:5037
* daemon started successfully
List of devices attached
Nothing appear on my phone as per the step 7 "On your phone’s screen, you should see a prompt to allow or deny USB Debugging access"
Can anyone help?

@MrFleas
1) go again on EVERY.SINGLE.STEP this may feel dumb to do but it could help
2) if it does not work, try googling for swr50 USB drivers, you may need to download Android SDK and drivers - then reboot - then start again at step one
3) come back here to thanks or asking for more help

Hi people, just realized we can also download the sony app to our phones (directly from phone or by using adb like on watch) so we can edit stock watch faces again =)
Here's the app to download to the phone: https://www.apkmirror.com/apk/sony-...ditor-2-0-0-20-android-apk-download/download/
Once installed, to edit watch faces, go to wear app, the edit watch faces =)

Seems like the same issue...
My hardly used smart watch is ALIVE again!
Thanks a lot guys!

I have latest but sync not working :/ i have a question is possibile install app with higher api or change apk API level ?

check the play service on your phone and install exactly the same version of the wear app
then it works

Cheers for doing this! Got my old smartwatch working cause of that. If anyone else reading this has issues at the' ADB device' point, and is using a linux based system, remember to use sudo on the commands -as otherwise i found that it would not enable the prompt to let me 'authorise' the device in order to send the apk to the watch.
Question- given that google have disabled the onboard step counter function on wear 1.5 devices (like this one), can we sideload a fitness apk via adb with this method that will then sync to our phones?

Hi, I've got the same issue. I had to change my phone. I've installed the same version of google play services on the watch with the description in this threat. But the phone is still not syncing the apps to the watch. Is there anything more I can do to trigger the sync (already triggered 'resync all app in Wear OS' without effect).

You might try to go Settings-Permissions on the watch and set the Permissions for your app. Sometimes I have got this to make the app work, when it is already installed on the watch but not working.

It works! I first downloaded this version of Wear OS for my phone:
Wear 2.43, the newest one somehow broke the sync for me.
By using ADB with " ADB install -r "I installed the last working Google Play Services for my Watch and also the last available version of Google Fit for Android 6.
Play Services : Play Services Wear OS - 20.45.16
Google fit : Google Fit - 2.10.36

[SM-R800][4.0.0.7]CSC Change Process

So I recently got a Samsung Galaxy Watch (SM-R800), but to my dismay, Samsung Pay was not available in it by default.
By searching on xda, I found out that running some simple sdb commands would do it, but unfortunately, it worked only in 4.0.0.4 version and mine had 4.0.0.7 out of the box.
Then I found out that the watch can be easily downgraded 4.0.0.4 and then perform the sdb shell commands, setup Samsung pay and upgrade to latest version again. Although finding the process was easy, finding the required firmware files took a lot of time, going through the threads and all. But I found them eventually.
To make it easier to come back to and to help wandering souls if any, I decided to create this thread.
Although I have written for SM-R800 specifically, it may work on other watches too as the firmware link has firmware for other watches too(R810,R805F,R815F,R805U,R815U).
Download links:
NetOdin3_1.0.zip
SDBstarterKidv1.zip
SDBstarterKidv1.zip
Firmware's can be found here : https://4pda.ru/forum/index.php?showtopic=978373&st=80#entry92121314
Following is the process I followed:
Charge watch, at least 90% . This is required as your watch will reboot many times during the process.
Set screen timeout to 5 minutes
Backup your data if any. This process resets watch multiple times.
Keep the WiFi password simple/open, you have to enter it multiple times in the watch during process.
Download
a. Old firmware
b. New Firmware
c. NetOdin3_1.0.zip
d. SDBstarterKidv1.zip
Reboot watch to Download (wireless). To do this:
a. Press and hold power button
b. When you see rebooting on screen, press power button a few times
c. You will get a menu like below
d. By pressing power button, highlight ‘Download (wireless)’ mode and then press power button long to select it
This puts the watch in WPS mode, but we need AP mode in this case. To switch to AP mode, press power button twice, you will see image as below:
Now on laptop/PC, connect to an open WiFi which has name of the device. In My case it was SM-R800.
After connecting, watch will continuously show “Connection timed out error 110”. This is fine.
Now open NetOdin3.exe as administrator. After sometime, the NetOdin window will show IP address of the watch and <ID:0/001> 192.168.49.1 in the Log window. If it is not connecting, try disabling firewall (or Windows defender).
Now once the watch is connected, select the appropriate files in three boxes. For me it was:
a. BL : BL_R800XXU1CSI1_usr.tar.md5
b. AP : AP_R800XXU1CSI1_usr.tar.md5
c. CSC : CSC_OXA_R800OXA1CSI1_usr.tar.md5
Just make sure watch is still connected (IP address is shown in Odin software)
Press Start button. After about 10 minutes, flashing process completes. During my process, it had failed once on by showing on the Odin software. All I did was reboot the watch in same way in Download(Wireless) mode and do the process again.
Complete the setup on watch.
Connect the watch to WiFi, even if doesn’t have internet it is okay. Note down the IP address(Settings>Connections>Wifi>Wifi Networks><connected_network>IP address).
Enable debugging on the watch(Settings> About Watch> Debugging).
REBOOT THE WATCH. Debugging doesn’t connect without it.
Now setup sdb to access your laptop.
a. Extract SDBstarterKidv1.zip
b. Extract zip inside it as per your Laptop/PC OS.
c. Run install.bat/install.sh as per OS.
d. Then go inside data/tools and run ansicon.exe as administrator. It will launch a command prompt window.
e. In it type sdb connect watch_ip_address
f. It will show connected.
I would recommend taking backup of your current CSC info. To do so type following two command in sdb:
a. sdb pull /csa/csc/csc-active-customer.inf
b. sdb pull /csa/imei/prodcode.dat
This will copy those two files in you current directory. The 3 ending letters are your current CSC code.
Now to change CSC, type following in your command prompt window:
a. sdb shell
b. You will get something like sh-3.2$ for prompt.
c. Then type: launch_app csc-manager.csc-pre-configuration
d. It will show “... successfully launched”
e. Now look on your watch, switch to CSC you want to . I selected XAR which is for US and at top of the list.
f. Touch on XAR and then it will reset your watch.
Now check if you have the Samsung pay app in the watch. If not there, You need to open the Galaxy Wearable app in the phone after pairing with watch.
In it, you will find the Samsung Pay option. Click on it, you will be asked to download the Samsung Pay plugin. Install from play store if available in your country or download it from apkmirror. If your phone is rooted, before starting the plugin app after installing it, hide root from the app in Magisk hide or something equivalent.
One thing to note over here is I had used US VPN to connect and setup over phone now, so if it doesn’t work in normally way, try using VPN. I used the TurboVPN, it has free servers too.
Do the setup on phone as well as watch by entering the card details.
At this point, the watch has Samsung pay, but it is still on the old firmware. And unfortunately, update operation from Galaxy Wearable app doesn’t show an update available. So, we need to again flash the latest firmware using Odin.
Repeat steps from step 5 till step 13.
Since the watch will be reset, the Samsung pay icon from watch goes away again, but it is available in the Galaxy Wearable app. Open it, sign in it. If card details were already added, they can be imported back from Samsung account.
Done!
Multiple times during the flashing process, either my WiFi disconnected from laptop or it failed due to some reason, but I was able to always reboot the watch in Download mode again.
I have some screenshots/images too, I will upload them soon.

Thank you @Mirhawk.
One of the best & most detailed explaination.

Does it matter which region firmware you download or are they the same? I Have SM-R810. Also, do you need to have Samsung Pay in the phone?

Thank you for a great explanation. I was stuck on R800XXU1CSD6 and finaly was able to upgrade to R800XXU1DSL1.
My R800 did not get any OTA after I change csc code to get Pay working.
Samsung Pay still works after this upgrade

"9. After connecting, watch will continuously show “Connection timed out error 110”. This is fine"
Anyway after my laptop was connected to SM-R800 i changed network settings (changed network for "public") and this error went off from my watch. Of course I switched off antivirus and windows firewall at the beginning.
After all I had the same problem when was installing last process of this instruction (new version). At first time i had fail but second time worked (maybe low signal from laptop or something dont know)

Which firmaweres do i need to download for SM-R810 with 4.0.0.7 ? I need to downgrade for chance CSC tu UK for samsung pay. I have SM-R810 with the DSL1 firmware right now.

does anyone know, why update no longer works after changing csc?

Just wanted to write here that it worked for me here in AUS, brought a SM-R800 grey import. Just follow the above directs to the T. lol just wanted to add that "e. In it type sdb connect watch_ip_address" watch_ip_address is your watches IP! rooky error. lol. also booting into AP mode I found tricky too but using odin and the cmd command the easy part! thanks again

It works perfectly. The key is to know what firmware do you need.

So I recently got a Samsung Galaxy Watch (SM-R800), but to my dismay, Samsung Pay was not available in it by default.
By searching on xda, I found out that running some simple sdb commands would do it, but unfortunately, it worked only in 4.0.0.4 version and mine had 4.0.0.7 out of the box.
Then I found out that the watch can be easily downgraded 4.0.0.4 and then perform the sdb shell commands, setup Samsung pay and upgrade to latest version again. Although finding the process was easy, finding the required firmware files took a lot of time, going through the threads and all. But I found them eventually.
To make it easier to come back to and to help wandering souls if any, I decided to create this thread.
Although I have written for SM-R800 specifically, it may work on other watches too as the firmware link has firmware for other watches too(R810,R805F,R815F,R805U,R815U).
Download links:
NetOdin3_1.0.zip
SDBstarterKidv1.zip
SDBstarterKidv1.zip
Firmware's can be found here : https://4pda.ru/forum/index.php?showtopic=978373&st=80#entry92121314
Following is the process I followed:
Charge watch, at least 90% . This is required as your watch will reboot many times during the process.
Set screen timeout to 5 minutes
Backup your data if any. This process resets watch multiple times.
Keep the WiFi password simple/open, you have to enter it multiple times in the watch during process.
Download
a. Old firmware
b. New Firmware
c. NetOdin3_1.0.zip
d. SDBstarterKidv1.zip
Reboot watch to Download (wireless). To do this:
a. Press and hold power button
b. When you see rebooting on screen, press power button a few times
c. You will get a menu like below
d. By pressing power button, highlight ‘Download (wireless)’ mode and then press power button long to select it
This puts the watch in WPS mode, but we need AP mode in this case. To switch to AP mode, press power button twice, you will see image as below:
Now on laptop/PC, connect to an open WiFi which has name of the device. In My case it was SM-R800.
After connecting, watch will continuously show “Connection timed out error 110”. This is fine.
Now open NetOdin3.exe as administrator. After sometime, the NetOdin window will show IP address of the watch and <ID:0/001> 192.168.49.1 in the Log window. If it is not connecting, try disabling firewall (or Windows defender).
Now once the watch is connected, select the appropriate files in three boxes. For me it was:
a. BL : BL_R800XXU1CSI1_usr.tar.md5
b. AP : AP_R800XXU1CSI1_usr.tar.md5
c. CSC : CSC_OXA_R800OXA1CSI1_usr.tar.md5
Just make sure watch is still connected (IP address is shown in Odin software)
Press Start button. After about 10 minutes, flashing process completes. During my process, it had failed once on by showing on the Odin software. All I did was reboot the watch in same way in Download(Wireless) mode and do the process again.
Complete the setup on watch.
Connect the watch to WiFi, even if doesn’t have internet it is okay. Note down the IP address(Settings>Connections>Wifi>Wifi Networks><connected_network>IP address).
Enable debugging on the watch(Settings> About Watch> Debugging).
REBOOT THE WATCH. Debugging doesn’t connect without it.
Now setup sdb to access your laptop.
a. Extract SDBstarterKidv1.zip
b. Extract zip inside it as per your Laptop/PC OS.
c. Run install.bat/install.sh as per OS.
d. Then go inside data/tools and run ansicon.exe as administrator. It will launch a command prompt window.
e. In it type sdb connect watch_ip_address
f. It will show connected.
I would recommend taking backup of your current CSC info. To do so type following two command in sdb:
a. sdb pull /csa/csc/csc-active-customer.inf
b. sdb pull /csa/imei/prodcode.dat
This will copy those two files in you current directory. The 3 ending letters are your current CSC code.
Now to change CSC, type following in your command prompt window:
a. sdb shell
b. You will get something like sh-3.2$ for prompt.
c. Then type: launch_app csc-manager.csc-pre-configuration
d. It will show “... successfully launched”
e. Now look on your watch, switch to CSC you want to . I selected XAR which is for US and at top of the list.
f. Touch on XAR and then it will reset your watch.
Now check if you have the Samsung pay app in the watch. If not there, You need to open the Galaxy Wearable app in the phone after pairing with watch.
In it, you will find the Samsung Pay option. Click on it, you will be asked to download the Samsung Pay plugin. Install from play store if available in your country or download it from apkmirror. If your phone is rooted, before starting the plugin app after installing it, hide root from the app in Magisk hide or something equivalent.
One thing to note over here is I had used US VPN to connect and setup over phone now, so if it doesn’t work in normally way, try using VPN. I used the TurboVPN, it has free servers too.
Do the setup on phone as well as watch by entering the card details.
At this point, the watch has Samsung pay, but it is still on the old firmware. And unfortunately, update operation from Galaxy Wearable app doesn’t show an update available. So, we need to again flash the latest firmware using Odin.
Repeat steps from step 5 till step 13.
Since the watch will be reset, the Samsung pay icon from watch goes away again, but it is available in the Galaxy Wearable app. Open it, sign in it. If card details were already added, they can be imported back from Samsung account.
Done!
Multiple times during the flashing process, either my WiFi disconnected from laptop or it failed due to some reason, but I was able to always reboot the watch in Download mode again.
I have some screenshots/images too, I will upload them soon.

Philips 48PFT5500 - Can no longer login to Google account

My TV is a 48PFT5500. I know it is old but it's all I have at present. It is running Android 5.1.1, last updated on 13 July 2018 which is the last version avilable from Philips. But now I can no longer log into Google Play Store. When I enter my username and password, it says my username or password is not correct. I have tried many times. I can log into my Google account without problems from other devices, so I know I am using the correct credentials.
After reading another thread, I guessed I needed to update the Play Services app. But obviously I cannot do this directly from the Play Store because I cannot log into it from the TV. Also, I cannot find any type of File Manager app on the TV, so I cannot even install the Play Store app from a USB drive. Nor can I install a File Manager app because I cannot login to the Play Store.
Also I tried switching on two-step verification on my Google account, but this made no difference.
I tried clearing the Play Services app cache on the TV, but it did not help.
I switched on the Developer options and allowed unknown sources and USB debugging, then I tried to connect with adb over wifi. But it doesn't work, adb says "No connection could be made because the target machine actively refused it". No message is displayed on the TV to accept the incoming connection.
Maybe there is another way to connect the pc to the TV with a USB cable ... maybe with a type-A to type-A (male to male)? Would that cause a problem due to both devices trying to output 5V over the cable?
Is there anything else I can try - I just want to update the TV to get as much use out of it as possible.
Any useful suggestions would be much appreciated. Thank you.

Hi, I replied to you on the other thread. I'll copy here the answer:
Hi man, i have the same TV and had the same problem. To fix this you have to unplug the TV and try 1 or two times. I did everything by Wi-Fi, after reading your post i purchased the USB cable but was not necessary.
I did this way:
1 opened cmd or powershell runned as administrator
2 runned adb connect xxxxx (IP address of TV)
3 accepted on the TV pop-up the connection
4 downloaded google service apk from apk mirror
5 used adb install -r xxxxx (location googleservic.apk dowloaded)
It worked! I tried in first attempt sideload -r but didn't worked. You have to use the command "install -r" to reinstall google service.

Hi TheRealCedax,
I previously tried to login to the tv using abd over wifi. I tried many times and every time it refused my connection. This time I tried what you said, and unplugged the tv, then tried again. It worked! So thank you very much for your advice.
Now I have sideloaded the Google services apk, and I can login to Google Play Store again. Obviously there are not many apps available! Not even a good browser.
Did you manage to find any useful apps anywhere?
Also do you happen to know if I can use a keyboard with the tv?

I have had the same problem but after 3 nights of trying diffrent things it is now sorted.
1. Factory reset the TV
2. set up tv as normal but dont bother to try to log into google.
3. On a laptop download Downloader.apk
3. Download ADB Tools from here : https://developer.android.com/tools/releases/platform-tools
4. Connect your laptop to the same network as the TV
5. Enable Debugging and Unknown sources
6. Connect to your TV using ADB (Google how to do this, its easy)
7. Install downloader using ADB (Again google how to install an app using ADB its super easy and takes a few seconds)
8. On the TV open downloader and use the code 48157 to install Apptoide
9. open Apptoide and install google play services, I also installed Youtube from Apptoide as well.
10. Close downloader and open the goole play store, the login will now work as its the new version of Google play services.
This may seem daunting but its actually very easy and took me 5 minutes start to finish. It works and you will have a fully functioning Phillips android tv.
