QAM tuning problem

[juanperez]

My HDTV Converter X1 device does not detect any QAM channel whatsoever, even if I select the "QAM-B Full Scan" option in the HDTVPlayer app. Besides, apparently the tuner only scans 35 frequencies, because it says: "Searching n/35 R(s)", but I have 55 channels going from 57MHz to 627MHz.

The QAM signal itself is OK because I can tune the channels just fine in a cheap 28 inch Daytron TV (DLED-28D1).

Another thing is that I can't find how to add the QAM channels manually either even if I know their frequencies, because apparently the HDTV interface only allows adding manually ATSC channels, which I don't need.

Notice this is all after upgrading to latest firmware (X1_v1.0_Y410.A11.1.6_20250519) and then performing a factory reset, uninstalling HDTVPlayer app and installing latest version (HDTVPlayer-42.2.42_apk) that I have been able to find in this site, which is what the QR in the device points to for official support.

I purchased this device precisely in order to tune QAM channels to display in my larger 43 inch Pioneer XumoTV (which doesn't include a QAM tuner), but I now feel very frustrated because even though the GTMedia device claims to support QAM tuning, I cannot get it to work.

Please, help.

I said "If not update from here....." . If you already on latest is fine. if the system works fine before doing the update try to roll back to the previous version until the next one. lets wait till someone with same problem helps

The device had exactly this same problem running the firmware version it came with, which is precisely why I upgraded.
Also, what variant of QAM does the device support, 64-QAM, 256-QAM? Both? I haven't been able to find technical specifications.
