The boot.img include in that article is outdated, so it will boot loop - not sure which firmware it is claimed to be from, but it certainly did not work with the version on my phone (Cant remember if I even checked for mismatch)

My issue was, I extracted the boot.img (from memory the path was slightly different {I will confirm this once I do this again}) patched it in magisk, flashed via fastboot and the phone would not boot, I left it for a good 15 mins, it just sits on the vivo logo.

I will try again tonight with the latest firmware, If it all works out I will include patched and unpatched boot files which can be checksum checked for security.

If the latest firmware has fixed the bootloader exploit, we can downgrade - though T-mobile, 3, 02 users will continue to suffer with call drop outs.

That one shouldn't be out of date and the writer keeps the most current version. based on update file. I was able to root with the most recent file and also have a boot.img.

Typically once the bootloader is unlocked, I haven't seen any oems use a relock in that way. I had to install the full may package before I actually could update to the most recent update (that removed root but kept blu intact).

Having said that here's the boot.img

https://drive.google.com/drive/folders/1Qog9HYxuouhlqaKJV0LfQff2TF5wdRbb?usp=sharing this one is for the most recent update. I'm not sure if you'll be able to use this boot.img though

If you change dpi when fold, only the extern screen will change. When you change dpi when the Phone is unfold, internal screen will change.

When I change it on the internal screen it also changes the external one and vice versa.

You're right... Sorry. When i tried 2 days ago it was working but now it's not... I had apparently a bug that disappeared with the new firmware received today...

Had to use wear (chinese version installed with vivo appstore) first, and health (samsung app) after. Worked for me.
Just ininstall wear us version if you have it....

Sorry, I can't seem to find the Wear app in the v-appstore. Would you be able to let a direct link? Thanks!

Is it the first option in the list pictured? The install button is greyed out for me. Crap.

So, have you updated to the latest and extracted this with the DSU method? - I assume you have not tried flashing the magisk patched image?

I tried this last night, again, bootloop when flashing the patched IMG.

I'm going to do a silly test, I'll extract my boot img and flash it back to see if that breaks anything, will determine if it's a magisk issue or fastboot on my PC - I've seen too many anecdotal posts about cables and USB ports causing problems....

Hi - thanks all who have contributed so far - love this phone but still an odd issue to work out.
My Ring doorbell notifications don't work!!
I have done all the usual (removed com.vivo.pem , disabled com.vivo.sps , battery , notifications , location etc.) but they just don't come through.
All other notifications seem to be fine

Anyone else having this or any other suggestions?

Thanks in advance

Technically you're supposed to pull your own boot.img with the instructions I provided using dsu loader. You shouldn't boot loop after flashing your patched boot.img and you will achieve root

 

[g_woodend]

Both

Thanks. Connection is just too flakey to be practical, no point in having a smartwatch if the connection isn't stable and you miss notifications. I know some people have it working fine but it's just not reliable for me so the watch is going back !

Going to try the Ticwatch Pro 3 Ultra

It was my own Image, patching with magisk or using fastboot flash breaks it, but as I said I'll test tonight to see if it's my machine as there is nothing else It can be.

Post this, need to find a way to strip out more of the Vivo crap, including any warning about launchers.
Changing accessibility options seems to ask for a vivo password every time, that will get boring very quick...
Google Assistant although set as default assistant still does not trigger via Bluetooth headsets.
All fun

I can’t say I’ve experienced that tbh with my rooting woes. The pull (once the instructions were provided) was painless.

I didn’t patch vbmeta though in magisk. I didn’t check the option. But after I got the patched image and uploaded it to my pc it was relatively straightforward thereafter

No...Wear os..

Oh, I thought you meant the Galaxy Wear app. I didn't know Galaxy watches work with the WearOS app. I'll give it a try. Thanks.

You will need both if them. Start with Wear os and when thé watch is detected open Wear Samsung... you will have to use health (Samsung) too if it's not working.

 

[jwilson77]

Did you also download the Galaxy Watch Plug-in from the v-appstore?

 

[francoiscox1]

No. Use play store for all Samsung apps. Just install Wear os chinese version. Then charge health Samsung. You will may be have to try different methods. Sometimes it works when you open Wear os first and open health just After, sometimes you just have to open health and look for the watch in the menu "accessories" (3 dots menu). The most important is to not install the Wear os us, only keep the chinese version.

Finally successfully root my X Fold.
System Version is 15.7, here's my original boot.img without patch, hope this is useful to you guys.

And this is the 15.7 OTA package link which I intercept by wireshark.

And is there anyone know how to connect Samsung Galaxy Watch 4 to Vivo X fold?
Tried for a few hours, but didn't get any solution.

 

[s960908]

No. Use play store for all Samsung apps. Just install Wear os chinese version. Then charge health Samsung. You will may be have to try different methods.

Sir did you use Galaxy wearable and Samsung Watch 4 plugin? Or just Wear OS China and Samsung Health?
I tried several times, but it never work.
