You could try the vivo downgrader (from ocean os to origin os) as long and if your device is supported.

Thanks. I will use the downgrader to return to earlier firmware and security patch and then try again to unlock and root with Magisk Canary. I need to enable VoLTE because my carrier won't provision it for Vivo products.

Vivo downgrader recognizes that the Vivo X Note but says "no downgrade images available yet".

It is in Chinese. In the folder this creates you will find a word document. It is the instruction guide. Open it in MS Word and use the translator function in Word to translate it into English. There are enough pictures in the instruction guide that once translated into English you can run the .exe file and know which of the buttons (which have Chinese characters) to click.

@frcraig did you manage to get VoLTE running? I'm in Canada, same provider as you, have same issue. Love the phone but sucks donkey balls my LTE speed is limited to around 30Mbs and no VoLTE.

I should have jumped on the unlocking tips provided on this forum several weeks ago, but didn't get around to it before the June Android Security update pathed the exploit. Now, in order to unlock the bootloader so that I can root with Magisk and enable VoLTE I have to downgrade to an earlier firmware and then unlock, etc. I haven't found time to do that yet, but we aren't yet at the crises point of our American neighbours who have shut down their 3G networks meaning no voice calls there on these phones without VoLTE. Interestingly T-Mobile does provision VoLTE for these Vivo phones, so some Americans will be OK. We are still two years away from shutting down 3G in Canada so while voice calls drop to 3G without VoLTE we can still place voice calls. I have a Google Voice number as well, so I can place voice calls with Google Voice over 4G or 5G while roaming in the US. It would be much easier for us if the four Canadian carriers followed T-Mobile's example.

For me it sucks when I'm on WhatsApp video call and need to send an attachment via MMS or download something it's soooooo slow. Didn't know about the 2yrs before 3G disposal, good to know. I have the 2022-04-01 security update so will be trying the VoLTE switch for my x70 Pro Plus.

I am not sure if it's my ISP or Vivo but my download bandwith is limited to 30000kbs do you think that can be adjusted once my phone is unlocked?

Under "Set Preferred Network Type" your setting GSM/WCDMA/LTE means your phone will connect first on an old 2G network, then if one isn't available it will connect on an old 3g network, and only if those aren't available it will connect on 4G (LTE). That setting also tells your phone not to connect on 5G. There are very few Rogers 2G towers left, so I'm guessing you are connecting on 3G for data and thus your slow download speed. You want to connect on 4G or 5G, so change the preferred network type to NR/LTE/GSM/WCDMA. That way it will connect first to 5G, then to 4G if 5G is unavailable.

This method seems to brick my device

I successfully unlocked my bootloader, the orange warning poped up. ( the same as shown at the top of this thread )

But I am not able to boot into the system or recovery. No prompt for erasing all the data appears either. I am stuck here.

Hi, I assume you have X80 Pro CN version. If yes did you try to install FunTouch OS? Regards'

It turned out that I haven't reboot for enough times. My device asked me to wipe data the next morning. Thank u for your help!

In theory it should be possible to return to OriginOS but we need an OTA update that is newer than 5.13.12.
Can anyone help out? I want to write a comprehensive guide to transform the phone in both directions.

Signal problem on FunTouch is not solved currently. No signal in LineageOS either.

Edit: Magisk Canary 24306 working on FunTouch OS.

how can you root your vivo phone? i've already unlock the bootloader and flash the magisk canary boot.img, it succes. But when i reboot to system, nothing happened, still no root and the magisk installed status is N/A. Can you help me?

sorry for bad english
