4I never got a reply to any of my private messages asking about the bootloader unlock, so here's the progress I've gotten on my own -
The Verizon ops files use slightly different crypto than the other variants like T-Mobile

Code:Oppo CryptTools V1.2 (c) B. Kerler 2019-2020 MIT License ---------------------------- Extracting instantnoodlev_15_O.07_201103.ops xml: 153330e00 Extracting prog_firehose_ddr.elf Extracting prog_firehose_lite.elf
With a bit of editing it's possible to reflash the phone to instantnoodlet_15_O.16_201001.ops (the T-Mobile variant) -- edit settings.xml and change the <BasicInfo> and <Target ID> tags.
With this comes the "OEM unlock" toggle in Developer settings, unfortunately ....
Code:fastboot oem unlock FAILED (remote: 'Please flash unlock token first.')
Code:fastboot.exe oem get_unlock_code ... FAILED (remote: Unknow command)
So, no bootloader unlock yet, but it is happily running the T-Mobile firmware.
(wifi, LTE and fingerprint appear working fine)
I may take another stab at it later using an EU or international firmware and see if that behaves any different.2
Good to hear, guess i'll keep waiting. Do like the feel and speed of the phone, definitely out performs my Moto z4
