Dear Moin,

If everything is okay it maybe Qualcomm SM8250-AC Snapdragon 870 5G (7 nm) Processor not support by UMT QC Tool.
You can try with DFT Pro

i have the same device Poco F3 & same issue. unable to read QCN with UMT or any other tool.
i replaced rsa with 10k & now someone suggested me to replace that with 33k & retry..
i will come back to this thread if it worked after 33k

UMT should provide proper guidance and a solution for this, but the UMT team has not responded yet.

i changed rsa to 33k because my phone was converted from china to global.
bt result is same. unable to read qcn.. my baseband is okay.

Regards,

same issue.. DFT isnt even detecting that diag port,
qfil => same
avengers qualcomm = same
none of the tools are reading qcn.. issue might be with the security patch.. unable to downgrade..
downgrade => system destroyed
eng rom => system destroyed
eng rom via edl => dead
only same or latest version can be flashed.
