I don't have the Vivo X Fold — am interested in getting it.

From what I've been reading there seems to be OEM unlock present in the settings…

Anyone rooted somehow? I haven't used a Vivo device yet — just Samsung, so with the restrictive Chinese approach assume there'd be no full firmware downloads, whereby Magisk patching tse boot would be easy. Or am I wrong?

I unlocked bootloader and rooted, I usee DSU Loader and dd command to extract boot.img from the device. (search it)
Note that the device must be before 2022-04-30 compile time to unlock bootloader, latest firmware blocks unlocking.
Many thanks! :0)

Is there a way to buy such a device online? Do you know any seller who will check and guarantee this?

I'm searching fro DSU loader info — never used it before — and reading up on it. Thanks for the pointer.

Just for more details if I may:

— dd boot partition — understood; Looking now for how to via DSU loader.
— Then you patch via Magisk Manager I assume, right?
— How do you then flash back to phone? DSU loader again? Or is that where it's “magic ” comes in, it creates a virtual partitIon somewhere, placed modified boot there and you boot off of it?
— If the above is the case, do you boot modified via some boot combo?
— If it isn't the case, could you briefly describe?

Many thanks. :O)

Does that mean after you unlock, you won't be able to install any Android updates or security patches (and remain unlocked)?

Maybe it's easier to use DSU Sideloader app.

The step to root is:

1. Download AOSP GSI (system-squeak-arm64-ab-vanilla.img.xz) from Phhusson

2. Once you prepared DSU, reboot from notification to boot into DSU's image

3. Connect USB cable

4. Run these commands in command prompt or powershell:
adb shell
su
dd if=/dev/block/by-name/boot of=/data/local/tmp/boot.img
chown shell.shell /data/local/tmp/boot.img

5. Exit adb shell and run this command to pull boot.img:
adb pull /data/local/tmp/boot.img

6. Patch boot.img with Magisk app

7. Reboot into bootloader and run:
fastboot flash boot magisk_patched_[random].img

No, you can get OTA update even after unlocking and remain unlocked.
First attempt will fail but then updater app downloads full zip automatically.

I'm trying to find a pre-end-of-April device seller online now… :O)

BTW — is there a clean reflash or something option to rescue Vivo devices — if you brick it after root? Just factory reset from Recovery would do I guess.

Reason being — sometimes you're too eager to do somethIng and end up in a bootloop — happens to me from time to time - and I guess here the risk would be significant having to freeze all the China bloatware…

I would think there is Recovvery reset — but best to ask, I've never seen a Vivo device…

Yes, factory reset from recovery or flash correct partition from fastboot (in case you flashed wrong/corrupted image).
There's EDL mode too, but I don't know if it can be used.

I'm communicating with some Chinese sellers on ebay - it's all shady in a regular way :O) - is the compile time printed somewhere on tthe box outside?

Or is there manufacture time there? And go by that? Could you tell me exactly where on the box - or, if possible, share a pic?

They're all saying - we can't break the seal and check, since then it's a used phone - logical. But also: don't worry it'll be OK - which usually means it won't… :O)

There's "生产日期" (Manufactured date) on the back of the box, and if it's 2022-04 it should have firmware with compile time before 2022-04-30.

My phone's manufactured date is 2022-06-27, and compile time is 2022-04-21.
I didn't install any updates yet.

The X Note and the X Fold share the same underlying Origina OS Ocean operating system. Each has slightly different versions of the firmware, with the latter being 'tweaked' for use with the tablet style screen. With both phones the exploit that existed that allowed unlocking of the bootloader was patched by June's security update. If you have updated your X Note recently then you can't unlock your bootloader. There are currently no "downgrade" firmware packages available via the Vivo downgrade application. If Vivo makes these available then you could downgrade to May's firmware and use the exploit described in the X70 Pro forum to unlock and then you could flash with Magisk and do whatever you need to do. You can't at present.
