Currently, I am trying 2 attach LifeView 52nd (T220+Sony) to libreelec version on odroid (kernel 3.14.29, See here). Was discussing the situation with CrazyCat (he is experienced indeed), received advice to install version W\O media build. Previously was trying media builds, but crazycat told me, that his drivers are OK from 4.4+ kernel). With regular drivers situation became much better, but w\o success. Ftontend and tuner are exactly visible in tvheadend (previously was not), but no tune 
dmesg

According to advice from CrazyCat, i made an attempt to look, what's going on during scan attempt.
./dvb-fe-tool -m -v
Device Sony CXD2820R (/dev/dvb/adapter0/frontend0) capabilities:
CAN_2G_MODULATION
.....
Supported delivery systems:
[DVBT]
DVBT2
DVBC/ANNEX_A
DEBUG POST BER not available
(0x00)
DEBUG POST BER not available
(0x00)
...
etc w\o any change during scan attempt. Looks, that tuning is not working from commandline, as other tools. While trying to do it manualy:
./dvb-fe-tool -f0 --set-delsys=DVB-T2
Changing delivery system to: DVBT2
ERROR Set delivery system: Bad address
Any advice?
