Sry for the following stupid questions but:
-) How do I start the program in win64?
-) Can I use this to dump the current android rom of my phone and get boot.img+vbmeta.img thus being able to root the phone using magisk?

Does the bootloader need to be locked to get into this preload mode and to dump the rom? I already unlocked it before.
Now if I hold up and down volume and plug in the phone Rom2box says "..handshake failed..". Rebooted after installing mediatek and usbdk drivers and I also tried different usb ports.

The same story for me, the phone can't be put in preload or download mode or whatever they call it. I know one thing it is my last Oneplus phone if they're all going to be pain in the arse like this one. I guess it's back to my old 6t for another while then.

Accessing it by way of Recovery mode is also broken. To try it yourself, boot in to Recovery, connect your phone to your computer with usb-c cable. Multi-tap version number, it will eventually ask you if you want download mode and you click yes. It will attempt reboot into download mode, fail and then will `normal` boot phone.

Hi, I just tried ROM2box 2.5. I got five of these messages then kicked into recovery `Preloader - [LIB]: [31mStatus: Handshake failed, retrying...[0m`
connect in Proper way= install Latest usbdk and mtk driver, start process turn Phone off press volume up & down key and then Insert USB, once the Phone is detected release keys

Thanks for the info, though I have been doing that setup all along. I dual windoze and Linux. My windows is a custom minimal version of windows 10 with feck all on it. I upgraded this phone to stock 12 beta yesterday and ROM2Box for a wonder is happily doing a dump of that. It should be interesting when I downgrade to stock 11 and try to do a dump of that.

Nice, May be BROM is disabled on stable version so you are not able to dump OxygenOS 11
Hi @mark332, sorry I wasn't able to get to you sooner about this. Coredump was only possible with OxygenOS 12.1 beta, BROM was definitely locked down in 11. I succeeded with 12 but 'out' folder looks incomplete, files like ''preloader' which is in the beta package are missing from the dump. I don't think I would be able return to stock with ROM2box, maybe manually with fastboot commands.

Well downgrading this phone from OxygenOS 12 beta 1 to OxygenOS 11 has left it without a working touch screen in the normal mode or recovery so it is now a dust collector unless Oneplus / Oppo are willing to fix it.

Ah you see, the fecking phone managed to rollback to 11 but the touch screen driver is broken I guess. Physical buttons work but touch is broken. So I have contacted Oneplus tech support so we'll see what response I get tomorrow.
