I used the latest nightly 20251105 and AVL6862-22.0.6.3
First, I tried the parallel DTB. It gave an Ir2c error. Therefore, tvheadend and dvbv5-scan did not perform a scan.

Couldn't find demux device node
WARNING device dvb0.demux0 not found
Then I tried the dtb series. Dmesg saw avl6762, but I couldnāt find it in either tvheadend or scanv5.

parallel and serial dtb files are exactly the same ragarding i2c setup, and in dmesg from serial dtb there are no i2c errors. Donāt know what You did, but it is for sure not related to dtb. Maybe You rebooted somehow from android which turned off the power to the avl ? I donāt know. Try again.
those pinctrl errors should happen from the beginning, the ts0 input pins configuration was wrong in all dtb files I sent You, I donāt understand why it worked before ā¦ Nevertheless try this, I hope the pin configuration is now correct:

Thank you very much for your efforts. Dvb-c is working now. 
During this process, I received very strange dmesg logs. I got two different results with the same dtb. I did a bunch of fresh installs.
Ok great, the box is MagicSee C500 Pro ? and the DVB-C is on TS0 serial input ?
The working dtb files are in this latest message. According to this, since DVB-C is working, you should know whether ts0 is serial or not. Because I only did a channel scan. Iāll send dmesg if needed.

@taki I compiled the driver for avl6261, You can try it:

and use this dtb:

Thanks. Tvheadend doesnt see avl6261 but

maybe i2c address is wrong, I took it from the availink repo. Do:
i2cdetect -y 2
Iām out right now, so Iāll try i2c2 again. But after dmesg appeared during the new rules setup, I ran i2cdetec. It found nothing for i2c, but only 0x14 for i2c3. I wonder if Iām using a common pin for sda and scl.
There might be wrong i2c configuration, try with this:

Is it working ? I think that in tvheadend there should be two frontends. In dmesg there were added two frontends but with the same index ā¦ put output of:
ls -al /dev/dvb/adapter0
I scanned dvb-s bu no find signal and channels. I will try

It looks OK, in tv headend also. actually in tvheadend the #0 is for frontend 0 and #1 is for frontend1 .
So first thing is to make sure that the DVB-S tuner works. I made a DTB with only DVB-S tuner and DVB-T removed. Try it:
sm1_s905x3_magicsee_c500_pro_4g_only_avl6261.dtb (77.0 KB)
If it will not work do the scan with dvbv5-scan (the same as You did for mecool K5 here S905X4 built in DVB - #169 by rozpruwacz) and paste output here
I am trying
