Enable ECG(BP Featur) On Non-Samsung Phones for Galaxy Watch 3, Active 2 Step-By-Step

Update 09/29/20:
1. The latest Samsung Health Monitor Version 1..1.0.175.Caravana (Thanks Caravana for the Mod) Download
This tutorial should work on all Android Phones to enable ECG for your Galaxy Watch 3 and Active 2. BP might also work the same way when it is released in the US.
Basic idea is to create your own certificate to sign ECG.tpk application and install it on your watch, then install the Samsung Health Monitor Mod app on your phone.
I have read lots of threads on XDA and can't find a complete tutorial about how to do it for Galaxy Watch 3 or Active 2. Hope this step-by-step tutorial will help. The whole process took me around 30 mins, it shouldn't be very hard. Make sure you back-up your watch first, just in case anything goes wrong and you need to restore data.
You will need an Android Phone, a Windows PC and Galaxy Watch 3/Active 2 watch for this tutorial. And a wireless network.

4. Reboot the watch. Make sure wifi is connected after the reboot.
From Your PC:
1. Launch Tizen Package Manager and Navigate to 5.5 wearable(It depends on your watch's software version, eg mine shows Tizen Version 5.5.0.1, so I navigate to 5.5 wearable), then click Install icon
2. Scroll down to the Tizen SDK tool and click the install icon
3. Click on the Extension SDK tab
3.1 Click the arrow on Extras

6.6 Now it will show your certificate has been saved at C:/Users/USERNAME/SamsungCertificate/cert_name and click next.
6.7 Create a new distributor certificate and click next

7. Open Tizen "Device Manager" from the PC.
8. Click the "Remote Device Manager" icon from top right corner.
9. From pop-up windows, click the "Scan Devices" icon from the top right corner.
10. Once it find your watch turn the connection switch to on. and close pop-up windows. At this time, you should able to see lots of debugging information from Device Manager. (If you don't see debug information, try these steps: 1. Turn off your windows firewall 2. turn off bluetooth&GPS on your watch 3. reboot your watch )
11. Go back to Tizen Certificate Manager, step 9.8, we can see one DUID has been added automatically. Click next.
12. It will show your certificate has been saved at C:/Users/USERNAME/SamsungCertificate/cert_name, Click Finish.
13. Download Fit2installer.zip unzip the whole folder to your desktop.
14. Go to the certificate(C:/Users/USERNAME/SamsungCertificate/cert_name) you just created and copy all files. inside the folder
15. Go to C:\Users\USERNAME\Desktop\Fit2Installer\cert Paste all the certificate file you just copied.
16. Copy ecg.tpk file and paste it at C:\Users\USERNAME\Desktop\Fit2Installer\sign_me

18. It will show "Package( C:\Users\USERNAME\Desktop\Fit2Installer\install_me\ecg.tpk ) is created successfully." and enter any key to close the window.
19. Now go to "Device Manager", right-click your device, choose "install app", Select ecg.tpk file from C:\Users\USERNAME\Desktop\Fit2Installer\install_me.
20. Wait a few seconds, you should see ECG app has been installed on your watch. Open it.
21. Open the "Samsung Health Monitor" app from your phone, you should be able to read the ECG data from your watch now.
As Blood Pressure has not been released in the U.S, once it released, you should be able to activate for Non-Samsung phone the same way. You can disable debug mode if you want now.
Enjoy!

Nice! I'm in the process of following this guide at the moment. Tizen Studio's package installers are so slow!

Nice to have well documented details! kudos

Step 6. I don't have a Samsung logo. When I click the + in certificate manager it just asks me for a certificate profile name

Is there a risk of voiding the warranty or bricking the watch doing this?

Is there an IPA file for this that can be sideloaded onto an iphone? I'm no expert at this stuff and have only followed the great instructions here before so not sure. Or is there any way to connect my GW3 to my Samsu g Tab S6 on Verizon that shares my iPhone number? I'd like to get the Health Monitor app features as I really don't want to go back to an apple watch.

Supposedly on tizen 5 there is no bp.tpk - ecg and bp are now both in ecg.tpk. installing old ecg.tpk may be main reason for bp not to work. Did anyone try to follow the tutorial but use new ecg.tpk? Does ecg.tpk need to be specialy prepared to by signed with certificate or can we do it with new ecg.tpk that has been posted by caravana?

Can there be a mess if in the future I change my phone and take a samsung?
Does the smartwatch remain unaffected? Will I always have to update it manually?

Works great!

Anyone else having issues w the carvana health monitor app? I keep getting an error saying it cant be run on a rooted phone...

hide it in magisk hide section of Magisk manager app.
Also, make sure you're passing safetynet on magisk manager & from manager's settings, enable magisk hide, also hide magisk manager & give it another name.

Thank you very much!! @xxstd
I had some problems running "sign.bat" due to relative path command routes, but after "customizing" the script changing to absolute path, all went ok.
I've signed BP.tpk and ECG.tpk and both are running OK in my GW3. I live in Spain, and here in Europe neither ECG nor BP are approved, so it is not the reason your BP tpk is not working IMHO.

Can you confirm the Tizen version from your watch? I know if you are runing Tizen 4.0.0.8 you could get BP works as well. Only ECG for Tizen 5.

Hmm, are you using the latest version Tizen SDK? Mine is Tizen Studio 3.7, they might change the UI a little bit for different versions.

Well, as the debugging mode has been enabled, if you tell Samsung they will possibly decline the warranty since they don't know what you have done to the watch...... But you can always turn it off, and reset the watch anytime you want.

How To Guide Install Google Play Services on Honor Magic 3 Pro [UI 6.0 Downgradable] Android 11 Packages

I manage to make GMS worked natively with some limitations (push notifications using Google FCM and Map showing on some apps which can be solved by downloading those app from AppGallery).
I have been updated the file to Honor GMSv2.zip to most of file are Android 11 (API30) and recent working version possible. My phone run:
Magic UI 5.0.0.189 now (Mar 1 2022 security)
I uninstalled the system update to avoid update to UI 6.0
no possible solution yet for 6.0 for gms installation, Google will be removed on first reboot on 6.0

What kind of limitations do you refer for? I am using Magic ui 5 with google service almost perfect without any restrictions.
I don't get the ui 6 yet, but if you got struck because G app logo (the google assistance), you only need to reinstall old backup app before you restore it.

No google maps on other apps like Google Photos, Uber etc. Of course limitations on notification.
Magic UI 6 beta, couldn't install with GMS installed, hence needed to reset..
Now, after restorring from old backup, I get G logo but unable to open it

It should have worked on old version of backup like Huawei. Be sure you have a change of date before restore (it is important step! )
The version of mine that worked is com.hihonor.koBackup-11.5.1.348-230501348.apk
If it is still not work out, It might be Honor phone updates to android 12 incompatible with the assistance app, you may downgrade to install it.

yeah, i am waiting for some solution or installation method for GMS on Magic UI 6. Let's see if someone is coming up on this.

I am using previous method to install GMS. my only problem is I can't update GMS because its is a system app now, P50 doesnt have this problem. IS there any other workaround for those system apps thing. P50 works fine with no errors or notification and all Google files are uptodate. Honor Magic3 Pro freeze when google wants to update gms when installing gboard.

To clearify, the previous method is just extended and also needless for Honor magic 3 pro where it only need to clear data on Framework to fix the error.
First of all, to update google services, you should go to play store and turn off app auto-update from the settings first.
The steps to update or uninstall are here:
-update using unsupported version for Google services (android 11 version any packages)
-reboot, You will see uninstall button
-Install any packages you want
The files are attached below! the second packages is 20.30.65 that is work great, you can try other version on android 10 for GMS to work.

As you mention, P50 is based on Android 10, and Magic 3 pro is on Android 11.
You can try to update the Google Services Framework from 10 to 11 to make it work flawelessly, still, some limitation on Map and push.
The procedures are the same as updating Google Play Services.

Thank you. Very clear.
The method i used was to insert GSF to google account, which allowed me to update smoothly on P50.

hi,
I tried on my Honor Magic 3 Pro Plus (Ultimate) but I can't uninstall the Google Services Framework. My phone can't fix the Google Play Services error message: this device isn't Play Protect certified

How To Guide Root Guide for Galaxy Tab S8/S8+/S8Ultra

See post #3 for in depth guide !
->insert usual general disclaimer of liability
Required:
Odin3_v3.14.1 flash tool
Samsung USB Driver installed
Frija or something else, to download stock files
7zip or similar
1: Unlock bootloader (will wipe your precious data, void warranty, break Knox e-fuse and who knows what else !)
-unlock dev option (just harass your Build number in settings)
-be connected to the internet (WiFi or 5g)
-allow USB debugging
-OEM unlock
-be warned that this might cause WWIII
-Power off your device. Press Volume Up + Volume Down THEN plug your Tablet lnto a PC to boot into download mode.
-Release buttons immediately when the blue screen shows itself.
-Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot
-Go through the initial setup.
-Skip through all the steps except wifi or 5g
-sign into your Google or Samsung account
-Enable Developer options & USB debugging
-reboot
-You have an unlock bootloader and have control over your device, (it is unfair that this voids your warranty as you should be able to use your hardware as you please).
2: Root install:
-Install Magisk
-use frija or something else to get the latest file according to your device and your CSC :
-patch the whole AP file with magisk (transfer of big files can be tricky, using SD card to transfer file from computer to tablet and vice versa seems like one if the easiest way)
-use odin to flash AP (the patched one), CP, BL and CSC (will wipe once again and reboot)
-Open magisk to finish install (reboot)
-You have root
3: Root update:
-use Frija or something else to get the latest file according to your device and your CSC :
-patch the whole AP file with magisk
-use Odin to flash AP (the patched one), CP, BL and Home_CSC (using CSC will wipe)
-Press and hold Vol-down and Power let go of all buttons once the screen turn on.
-You have root, data kept and update
Please let me know if something should be added or edited.

Hi @Vinsang! Thanks for the nice post. I'd like to suggest you edit the type of thread this is and make it a "How To Guide" instead of "Question" thread. That will help it stand out, especially if anyone uses the Quick Filters at the top of the list of threads in this section.
Edit: Thanks for changing it. Cheers!

​Step 1 - Prepare your Tablet (only necessary for first install on unrooted device)​
While Frija is downloading the firmware, prepare your device by doing the following:
Settings > About Tablet > Software Information > Click Build Number 7 times quickly
Developer Options (just below About Tablet on the left column)
Turn on USB Debugging
Turn on OEM unlocking
NOTE: If the OEM Unlocking option doesn't appear, connect the device to the internet, wait a few minutes, then try again
Power tablet completely off (Hold volume down + power button if you haven't changed the Bixby settings)
While holding volume up and volume down, plug the tablet into your PC via USB
Let go of volume keys as soon as the blue-green screen shows up
Press and hold volume up for 5 seconds, the screen will change to a confirmation prompt
Press volume up again to confirm, the tablet will reboot
Unplug your tablet from USB
Go through initial setup. Don't bother copying files or installing anything.
Skip signing in to your Google account and Samsung account. You won't be using them for this step.
Settings > About Tablet > Software Information > Click Build Number 7 times quickly
Developer Options (just below About Tablet on the left column)
Turn on USB Debugging
Reboot the tablet
​Step 2 - Patch the stock firmware to make it rooted​
Frija should have finished downloading by now, unzip the file (remember where you unzipped it to)
Plug your tablet in to your computer via USB and click Allow if it prompts to allow data access
If this is your first install / you're rooting the tablet for the first time:
Download Magisk-vXX.XX.apk from the topmost release at https://github.com/topjohnwu/Magisk/releases
Copy the Magisk-vXX.XX.apk and the AP_xxx_xxx_tar.md5 from the zip file Frija downloaded to:
This PC > Galaxy Tab S8 Ultra > Internal Storage > Download
Open the My Files app on the tablet and browse to Downloads
Click the Magisk-vXX.XX.apk and it will prompt you to click Settings
In Settings, turn on My Files, then it will give you a prompt to Install
When Magisk is done installing, click Open
If your tablet was already rooted, and you're just updating:
Copy the AP_xxx_xxx_tar.md5 from the zip file Frija downloaded to:
This PC > Galaxy Tab S8 Ultra > Internal Storage > Download
After the file is done copying, unplug your tablet from USB
In Magisk, click Install in the top Magisk area, then the option for Select and Patch a file
Click My Files > Downloads, select the AP_XXX_XXX.tar.md5 file and click Done at the bottom
Click Lets Go -> After a few moments, it should display this (ignore 'Installation failed' at the top, it always does that):
Step 3 - Apply the rooted firmware​
Plug your tablet back in to USB, then on your PC, go back to This PC > Galaxy Tab S8 Ultra > Internal Storage > Download and copy the magisk_patched-xxx.tar file back to the folder where you unzipped the zip file from Frija
After the copy is finished, unplug your tablet from your PC and completely power off your tablet
While holding volume up and volume down, plug the tablet into your PC via USB
Let go of volume keys as soon as the blue-green screen shows up
Click volume up (the side of volume nearest the power) briefly (don't hold it) to go into download mode
Start Odin and accept the disclaimer prompt
Click BL and select the BL_XXX_XXX.tar.md5 file where you unzipped the zip file from Frija
Click AP and select the magisk_patched-XXX.tar file
If this is your first install / you're rooting the tablet for the first time (this WILL wipe your data):
Click CSC and select the CSC_XXX_XXX.tar.md5
If your tablet was already rooted, and you're just updating (this WILL NOT wipe your data):
Click CSC and select the HOME_CSC_XXX_XXX.tar.md5
Odin should now look like this:
Click Start. When it's finished, Odin will display "PASS!" and the tablet will automatically reboot.
Step 4 - Verify and finalize​
Go through the normal setup, signing in to your Google and Samsung accounts this time
Click on Magisk that is now pre-installed, and go through the Settings step to allow it to install again
It should prompt you that your device needs additional setup and one more reboot, click OK
After rebooting, your device should be fully rooted. Use a root checker app if you want to verify.
​Step 5 (optional) - Get Netflix (and banking apps etc) working with root​
Install https://github.com/Fox2Code/FoxMagiskModuleManager/releases and run it
Search for Universal Safetynet Fix by kdrag0n and install it
In Magisk settings click Systemless hosts, turn on Zygisk, turn on Enforce Denylist
Click Configure Denylist, then the 3 dot menu and Show System Apps
Search for Google Play Store, click it, check the check and turn on all options underneath
Search for Google Play Services, click it, turn on .gms and .gms.unstable ONLY
Search for Netflix, click it, check the check and turn on all options underneath
(optional) Add your bank / pay app, etc here if you'd like
In Settings > Apps, search for Google Play Services and Google Play Store and clear all data (not just cache) for each
Reboot
NOTE - This is currently only passing Widevine level 3, so Netflix is limited to SD. I'm still trying to figure out how to get L1 / full HD.

Is there currently any way to make nandroid backups without TWRP since there isn't a build of it for the Tab S8 line yet?

Not you can't make a full nandroid back up without TWRP for the moment. You can use Swift backup or something similar to backup some things in particular, Google backup is also pretty convenient.

Anyone work out how to get Netflix working with root yet? Also, is Magisk manager showing any modules to download in the Magisk app for you guys? I can install from file, but the downloading functionality doesn't seem to be working.

Dunno about Netflix, but this worked for banking apps:
Add this module : https://github.com/kdrag0n/safetynet-fix
Zigisk and enforced denylist on and add Netflix (or other) in the deny list. Reboot and tryout.
It seemed that the download section isn't there anymore on the latest magisk, same on other devices. You gotta download them separately.

Not sure when, but somewhere in an update, the ability to download modules from magisk directly was removed. You can download them using an app called Fox's Magisk Module Manager. You can search for modules just like you could on Magisk, and they'll be added once you install them and reboot. Also, for the netflix thing, your device may not be passing safetynet. Checking this was also remove in an update, but you can check it with YASNAC.
Edit: I just did this with my rooted Tab S7+, but it should work with the S8+ and S8U as well. Doing this should let you pass safetynet and be able to use Netflix.
1. Enable Zygisk in Magisk settings, then reboot.
2. Enable Enforce DenyList in Magisk settings, then go to Configure DenyList.
3. Enable show system apps with the menu on the top-right, then search "google play services".
4. Enable DenyList for com.google.android.gms & com.google.android.gms.unstable, then reboot.
5. Open YASNAC to run safetynet attestation, you should be passing basic integrity but failing cts profile match.
6. Download and install the latest version of the safetynet fix for zygisk module, then reboot.
7. Check YASNAC again, you should now be passing basic integrity and cts profile match.
8. Go to settings > apps, find google play service & google play store, clear data for both of them, reboot.
9. Go to the play store > settings, play protect certification should now say "device is certified".
10. Open Magisk > Configure DenyList, search for Netflix (enable show system apps if you need to), enable DenyList for everything, reboot.
11. Update Netflix if it's not up to date. If the play store is allowing you to update Netflix at all, then you're good to go.
Now you have Netflix running on your rooted tab!
Edit 2: Accidentally saved my first edit before I finished the instructions, my bad.

Excellent guide. I just had my OOBI this morning & I forgot about having to change the date to an earlier one, check for a software update, etc before being able to see OEM unlock in developer settings. But that's a one & done.

To download magisk modules use this app; https://github.com/Fox2Code/FoxMagiskModuleManager
To hide root you can try this:
1. Magisk -> Settings -> Hide the Magisk app (It will get a new random package name so other apps won't see that it's actually Magisk and additionally you can choose a new name for the app as well.)
2. Open the newly created magisk app, install extra files when prompted and tab will reboot automatically.
3. Flash MagiskHide Props Config https://github.com/Magisk-Modules-Repo/MagiskHidePropsConf/releases
4. Reboot
5. Flash Universal Safetynet Fix https://github.com/kdrag0n/safetynet-fix/releases
6. Reboot
7. Add any app you want to hide root from to DenyList: Google Play Store, Google Play Services, Google Services Framework, Netflix, banking apps etc.
8. Enforce DenyList MUST stay turned off!
9. Flash Shamiko module to hide root properly.

After checking Frija, found that an update was available fro my SM-X906B EUX, Just updated to X906BXXU1AVCD/X906BOXM1AVCD/X906BXXU1AVCD using step 3 of the guide without issue (root and data kept).
Is there a way to be notify when an update is out ? Or do i have to manually check every month?
Do we have changelog or something similar?

Someone else had given the link to this site (for your model) https://samfw.com/firmware/SM-X906B.
No automatic notifications, but I use a Windows program that checks sites for updates (https://samfw.com/firmware/SM-X900 for my model, which won't arrive for another 12 days).

Quick question. If another software update were to come out, could I update it and still have magisk and root access afterwards? My Tab S8+ says its device status is official, and it doesn't tell me that my device is rooted when I connect to the server to check for updates. So, if I updated this way, would that remove the whole patching the AP file with magisk and flashing it with Odin thing? It'd be awesome to have the latest updates and such while maintaining root access.

To keep root and your data while updating, follow the step 3 of the guide in post #1( it requires that you look manually for updates).
I wouldn't advise to update via OTA while rooted. I don't even think you'll get the prompts.

That's odd because I got the prompt to update on my rooted Tab S7+ (it also says the device status is official) when the OneUI 4.1 update came out for it. I haven't tested to see if that would change anything, but since the S7+ has TWRP, I can just restore a backup Incase something doesn't turn out well.

Hi all. I purchased a SM-X900 from the Samsung website(UK). I am having a serious problem with getting the OEM unlocking option to display in the developer options menu. I have tried the known workarounds (change date/disable automatic updates, etc) but had no success. Does anyone have any other methods/ideas? I previously had the tab s7+ and had no problems with this.
Any tips would be much appreciated!

I've had some issues where after enabling OEM Unlocking and going through the process, after Unlocking and resetting, the option disappears, but OEM is still unlocked. Not sure what causes this, but after rebooting for some root-required things and checking again, the option was there and changeable. I actually went throught the normal initialization process on my Tab S7+ and Tab S8+ (wifi, clock, samsung account, etc) and never had any issues. Maybe try either factory resetting again or flashing latest stock firmware (you can flash official firmware even if oem is locked). YMMV though. This specific issue of the option not showing up at all never happened for me, so I'm not sure how much help my suggestions will be.

Well, something I can recommend is downloading the latest firmware update for your specific device (use either frija or samfw), going into download mode by holding vol+ and vol- while connecting the device to a PC, and flashing it with Odin, or you can update officially since your device hasn't been rooted yet. Maybe the current version you're on is affecting it somehow? No clue man. This issue is brand new to me.

[GUIDE] Installing GMS on Huawei P40 Pro with EMUI 10

New method that worked for me (2023/01/21) here. If the below method doesn't work, try it.
----------------------------------------------
After literally a year I have GMS on my P40 Pro again!
What worked was following a tutorial that badmania98 shared (thank youuu)
I didn't see anyone comment about this so here's what I did that actually worked.
First of: My device is a Huawei P40 Pro with EMUI 10 - 10.1.0.176 (C432E8R6P1). I don't know if it works with other EMUIs/devices. It should according with the video tutorial.
Steps:
0 - Some steps won't happen like you see on the video, so read carefully.
1 - Watch the whole tutorial first: The link to the tutorial: www.youtube.com/watch?v=7kGkLsf83Bk
2 - Download the app to your device and the HuaGu PC ADB to you PC.
3 - Turn off wifi and mobile data on your device, turn off the internet on your PC (this is just for security reasons, may not be really necessary. I did it)
4 - Do all the PC stuff you see on the video and also step 1 and 2 on the HuaGu app.
5 - When you reach step 3 of the HuaGu app, you may get stuck on the Restore Backup process. Let it run for a minute, go back, and if the step 3 doesn't have a check, do it again. On my 2nd try I got a check on step 3 and moved on.
6 - Turn on wifi or mobile data on your device.
7 - When doing step 4 of the HuaGu app, it should open the Google Service Assistant (that app with the purple G), gives you a error in Chinese and you won't see the same screen as in the video tutorial. Just got back to the HuaGu. It will give you a hint about not knowing if the Assistant did anything (In my case it appears that did nothing, but the whole thing worked anyway).
8 - Do steps 5, 6, 7, 8 and 9.
9 - Open Google Play Store. You'll get those annoying notifications about the not valide device / certifications / whatever. Press retry, open, close, retry and eventually Google Play Store will open normally even with all the notifications popping up.
10 - Install Google Maps. It's going to be annoying to do because of all the notifications.
11 - Open Google Maps and confirmed that you are logged in to your account. Move around the map a bit.
12 - Leave the device showing notifications for a minute or two.
13 - If you still have the annoying notifications (you probably will), go back to the HuaGu app and press on step 10.
14 - There, press step 0 and go back (I didn't register anything here. Maybe because at one time I had GMS on this device, dunno).
15 - Do all the other steps like it says.
16 - Open Google Play Store and disable automatic updates. Close it.
17 - Reboot again.
18 - Open Google Play Store, open Google Maps. If everything is working and without annoying notifications, uninstall HuaGu, Google Service Assistant and that backup restore app. Also, go to your downloads folder and there should be a bunch of APKs that were used during the tutorial. You can delete those as well. Turn off Developer Settings if you don't use them.
Congrats!!! You should have GMS on your device!! I only tested with Maps because it's the only app I really care about that needs GMS to be work so I can use all its features.
Thank you badmania98 and Average Logs!

so i have to roll back the EMUI from 12 to 10 first right?

Is your Google account on phone Settings\Users & accounts\Google ?

I tried about 20 times to do according to this instructions with HuaGu2.
Tried 10 times with HuaGu3.
And every time the same result: after uninstalling MicroG and installing Google Play Services, there is no Google item in Settings, no Google accounts (although there were MicroG accounts) and the Play Market asks to enter.
I have a Huawei P40 EMUI 12 Europe phone. I tried several different firmware, downgraded to EMUI 11 - the result is the same.
Have you come across such cases? What to do?

Not working for me either, same reason. When i uninstall microg, it also uninstalls my google accounts
P40 Pro, 10.1.0.176 (c432)
Any suggestions?

Yes, I was going to try that. But when I tried to downgrade via your Dload method (like i did before to get to 121) it wont let me downgrade now. It is now on 230. I've formatted memory stick, put dload folder back on it and tried again but it stays at 230. So why before it let me downgrade but not now? I dont get it.

From 11.0.0.230 to 10.1.0.121 you never ever have to use dload method. I never recommend this.

5 - When you reach step 3 of the HuaGu app, you may get stuck on the Restore Backup process. Let it run for a minute, go back, and if the step 3 doesn't have a check, do it again. On my 2nd try I got a check on step 3 and moved on.
6 - Turn on wifi or mobile data on your device.
7 - When doing step 4 of the HuaGu app, it should open the Google Service Assistant (that app with the purple G), gives you a error in Chinese and you won't see the same screen as in the video tutorial. Just got back to the HuaGu. It will give you a hint about not knowing if the Assistant did anything (In my case it appears that did nothing, but the whole thing worked anyway).
8 - Do steps 5, 6, 7, 8 and 9.
9 - Open Google Play Store. You'll get those annoying notifications about the not valide device / certifications / whatever. Press retry, open, close, retry and eventually Google Play Store will open normally even with all the notifications popping up.
10 - Install Google Maps. It's going to be annoying to do because of all the notifications.
11 - Open Google Maps and confirmed that you are logged in to your account. Move around the map a bit.
12 - Leave the device showing notifications for a minute or two.
13 - If you still have the annoying notifications (you probably will), go back to the HuaGu app and press on step 10.
14 - There, press step 0 and go back (I didn't register anything here. Maybe because at one time I had GMS on this device, dunno).
15 - Do all the other steps like it says.
16 - Open Google Play Store and disable automatic updates. Close it.
17 - Reboot again.
18 - Open Google Play Store, open Google Maps. If everything is working and without annoying notifications, uninstall HuaGu, Google Service Assistant and that backup restore app. Also, go to your downloads folder and there should be a bunch of APKs that were used during the tutorial. You can delete those as well. Turn off Developer Settings if you don't use them.
Congrats!!! You should have GMS on your device!! I only tested with Maps because it's the only app I really care about that needs GMS to be work so I can use all its features.
Thank you badmania98 and Average Logs!

I am unable to make a backup with Huagu pc app. And I suspect that is because I have FW10.1.0.121 and data transfer and fast charge is disabled, right?​
Help much appreciated. Thx

The guide that I posted on the top doesn't work for me anymore - Device not certificated errors. It stopped working around last November. However, today I found a tutorial that works:
So new Tutorial:
Link here
WHAT I DID DIFFERENTLY:
1 - His version is 10.1.0.134 but I'm still on 10.1.0.176 (superior) and it worked.
2 - Maybe because of that, the process of Backup & Restore doesn't worked. The password isn't "icfix1net" anymore, it's "a12345678" or whatever is in the password tip. Still, couldn't restore. So I skipped opening that chinese app.
3 - Google Play Store didn't installed - said it's already installed (which isn't). I continued anyway.
4 - From this point forward I did everything like the tutorial except the parts that involve Google Play Store and the activation of syncing contacts.
5 - Uninstalled the Backup & Restore app.
6 - Done.
Notes:
- If you want to install apps just use the Aurora Store. It uses the apps from Google Play Store so it's safe. I installed Google Maps from there to do the testing.
- Google Play Store is what actually messes everything up because it updates itself and GMS. Either don't install it or block its access to the Internet (you can do that in the settings or use a firewall or whatever).
- If this doesn't work, try to follow the whole tutorial. Who knows. Like I said in the beginning, this is what worked for me.
- If you need to downgrade there are links in the video description, plus there's a lot of tutorials there on XDA for that.
Side note: If you noticed, he has a P40 Pro with unlocked bootloader. I don't know what's the point since there isn't root or custom ROMs available, but it can be done (probably paying). Mine is NOT and it doesn't make a difference in the process.
Good luck everyone !
EDIT: Late reply to everyone:
- Yes, the Google account is in the Settings.
- This new tutorial doesn't use the PC so try this.
- About all firmware questions I can't really answer. I have 10.1.0.176 and never done a downgrade. I simply never updated after that and always disabled the auto updates.

Hiya XDA People, Today I will be showing you how to install GMS with full downgrade, this tutorial works flawlessly and you can give it a shot!

apologies for my late response, but I have another tutorial that is supposed to be followed which is updating GMS, so follow that one and you're good to go.
