    Additional dual T2 terrestrial tuner causing issues on Vu+ Ultimo4K

    I've recently purchased a third dual T2 terrestrial tuner from WoS for the Vu+ Ultimo4K.

    The first attachment shows the tuner config before adding the additional BCM3466 tuner. Everything works ok.

    The second attachment shows a working config. Tuner F has to be disabled.

    The third attachment shows what happens when tuner F is enabled. Tuner B becomes DVB-C, (as does tuner F) but the modes remain DVB-T2. Tuner B no longer works.

    The fourth attachment shows what happens when tuner F is configured as DVB-C, mode: DVB-C. Tuner B starts working again.

    There's also a debug log (ABM "start scan" is an easy way to get tuner B to fail) and a dmesg.

    I'm sure there must be some telnet commands to provide the nitty gritty details.

    Maybe I should also add that the BCM3466 tuner started life as DVB-T2 only, and was only turned into dual at a later date.

    This problem is in VU+ drivers 2019-04-24. With earlier drivers you could use BCM3466 tuner only as T2 not C.
    With those earlier drivers all six T2 tuners were ok.

    If I configure tuner B as DVB-C, and tuner F as DVB-T2 (as it should be), reboot, I get the spinner during the boot.....

    Attachment shows what it comes back with (had to delete timers+autotimers to get it back), tuner B now DVB-T, tuners E and F now DVB-C.

    Getting back tuner B to DVB-T2 doesn't work unless I save it explicitly as DVB-C and then save it as DVB-T2.

    Can you try an older image without the multi-tuner commits?

    You can't set tuners to be both dvb-t and dvb-c at the same time.

    Tuner A & B is 1 dual tuner

    Tuner C & D is 1 dual tuner

    Tuner E & F is 1 dual tuner

    So A & B need to be both set the same as each other, as does C & D and E & F

    A & B both dvb-c

    C & D both dvb-t

    E & F both dvb-t

    As an exmaple.

    I'll give it a go - I'd swear blind the archives didn't go back far enough when I was trying the tuners out, but they do now.

    I know, I'm not trying to use DVB-C at all, but configuring them all as T2's results in tuner B becoming a DVB-C.

    I've gone back to 5.1.033 (rings a bell now), dated 27/08/2018, which must be too old, as the box only shows tuners A and B.

    I need an image nearer to but older than 24/4/2019, 5.2.037 maybe.

    I gave up long time ago with Ultimo 4K/six T2 tuners. At the moment my Ultimo has one FBC-S tuner plus one MTSIF dualtuner, one older T2 dualtuner and one Sundtek T2.
    Works fine with five T2 tuners.

    ...... My "long time ago" only started 3 weeks ago, so I haven't given up yet.

    I've got vuplus-image-vuultimo4k-20190130152824_usb.zip running with 6 tuners configured.

    I'd tried the one dated 18/02/2019 some time ago but couldn't get the tuners to work as expected, maybe I should have gone back further.

    I've lots of timers running (up to a timer conflict), anyone know how to find out which tuners are actually in use??

    Found another skin which confirmed all 6 tuners active (and I've repaired a water leak under the landing floor. )

    EDIT: Is there anything else I can do before wiping the image ?
