[Upgrading, Modifying and Unlocking] kukulukuk:
You can't even connect to qcom port, if you try to by pressing vol-up+vol-down&connecting a usb cable the bootloader will be triggered to boot into their fastboot screen. So there's no way you can use emmcdl here.

But I haven't tried downgrading by forcing a corrupted system restore download (the method that needs wifi to reinstall the system). a corrupted restore is done by forcing the phone to power-off when the restore progress reaches between 90-99%. We accidentally did that a few years ago. I thought the phone was bricked by that but no, instead it boots normally without any FRP screen appearing, even the screen-lock was gone, like getting a new phone out of its box.

you don't type ./ if fastboot was installed with apt. you don't need 9008 driver, linux kernel already provides it. the best tool is bkerler/edl (but you may get some basic linux skills first before messing around with phone?)

I first extract the platform tools by google and replace fastboot binary with https://drive.google.com/open?id=0BwcKR-Av9XBcc0VKd3JKai1oQnM in '

I operate as the my last post in the 'platform-tools' folder
[Upgrading, Modifying and Unlocking] alecxs:
It's always good to post exact command and output ;)

adb reboot fastboot is typically used to enter fastbootd mode, while adb reboot bootloader will enter fastboot mode (but I don't know for vivo)

you can double check the file type with

$ file ./fastboot

Hey Dev! It seems that you used a very old version Ubuntu release to compile the fastboot elf in binary folder, the kernel version is 2.6.

I can not run the file in my 12.04 and 16.04, I have no ways but use 10.04 to execute that file, but it required glibc2.4, so still didn't work.
