I repacked installation packages to fix some install issues.
Install SDcard version to internal connecting to box via ssh and submiting command: /flash/installtointernal
Don't use kszaq version of 'installtointernal' otherwise u brick your box.
Internal flash versions:
Unzip file to SDcard or USB stick. Install from recovery or Android update apk.
i tested dvbt2, scanning fail but dvbs2 working well. blutooth also working successful. i aware that dvbs2 signal low 10% compare to my enigma2 box. normal signal for certain transponder 80-90%, but with k2pro around 70-80%. . tuner sensitivity also weak, this factors gave no signal or lost during scan or livetv. i dont know what is the minimum signal that suitable the box to scan successsfully.
Signal level is very informative value and hard to compare between different boxes. Most important is SNR. 50% is enough for HD channels. Most important parts are satellite dish and LNB. Tuner can hardly improve bad signal. If u have low signal on tuner u have to use LNB with higher gain.
