@iceman198 I unlocked the bootloader. It was not difficult, by the way. I wrote to the chat support, gave the SN, IMEI, Unlock code, PCB num (*#888#) and the purchase proof. They sent me the unlock file within 2 hours.

@Keneda yes

The driver seems to be fine

I've got a Oneplus Nord N10 5G, TMobile version, with unlocked bootloader. ROM version is 10.5.8. Didn't find the patched 10.5.7 version for this model.
Got stuck at the step of downloading UT files via UBports installer. Disabled firewall, enabled VPN, but with no success. Did anyone face the same problem?

@rocket2nfinity verified that. Oneplus Nord N10 5G. The OS version is 11.0.15 BE88CB, device name: lito, model:BE2028.
The OS version took from here https://devices.ubuntu-touch.io/device/billie/release/noble/
See, the device name in the url - billie.
I don't think there is any hardwear difference between lito and billie. It's rather a problem inside the installed ROM, which was developed for a specific carrier or vendor. My case is TMobile phone.

@NoodleCollie Hello! how did you manage to downgrade? I bought a oneplus nord n10 5g fo UT, and it's a "lito" model for Tmobile. I unlocked the bootloader and tried to downgrade with MSM from the UT device page. It gives me an error !
Did you face something like this?
