Last firmware for old GT1 please

alfonsomu01

Hello,  I have an old GT1 TV Box with 32Gb and:
- android security patch level: 1 august 2016
- android version: 6.0.1
- compilation: GT1_113MO
S/N: AP12FSGH....

could you, please, tell me how to set it to the last existing updates (firmware, android, ...)?


Thanks in advance!
