tanix is just as bad as beelink... lots of variations for one primary model.

anyway, for the price of rm10x for tx3mini, u can upgrade to tx3 max yrself...

or buy rm13x for a tx3max... such prices, nothing more to ask.

both can do all popular apps incl astrogo, unifi playtv.

tx3max is better - alice UI, faster, bluetooth, auto framerate switch.

native player is not so good but can use kodi to playback dts/dd/dd+/dtshdma/ddtruehd... expectedly, it cannot handle full bluray bdmv smoothly.

still, with such a low affordable price with good capabilities, nothing more to ask.

tx6 is not a good model, imo.

i hope tanix will soon come out with a new AML s922x model... i will be interested.

for its price, nothing is likely to beat what it can do.
but not good for you... becos u and some others always look for netflix HD.
no tanix model offers this or claim to be able to do L1-netflix hd/4k... so, no headaches with fake, temp, yes/no L1...
seriously, get a new 4k hdr tv with netflix - your life becomes much easier... have more time to actually watch nice videos.
i hear there is some problem now with imports of boxes w/o sirim/mcmc certs, not sure.
to be safe, buy from local sellers since the stock is here already; u can check this one:

honestly, if u haven't been mucking around with such boxes, my advice is dun try to upgrade firmware.
it can be a nightmare... u might give up and be left holding a brick or paper weight.
about kodi, i can tell u 3 things:
.. kodi USED to be a fabulous app but due to copyright issues, court cases, nobody is putting anything great there anymore, except..
.. quasar/elementum - these addons, u need to know enough to install properly for it to work.
.. kodi as a player for local playback is good, i.e. yr own video files on HDD, plug into USB to play. (instead of using native "movie player", mx or vlc.)
YES, tested good.

could be very old firmware...?

can u check what version it is?

that is one of the worst practices when using a box. if u keep doing that, 16/128gb will not be enough!!

and yes, best to shutdown to close off everything than put on standby.

can u just go into settings and find what version?

that will tell if it is too old or a proven good version, if something else is wrong.

if a year ago, it shouldn't be too old.

about firmware upgrade, u can read back... some need not do it...

some upgraded to tx3max firmware... some ran into problems... some like upgrade x but some others preferred y... seems mixed results.

my own experience was not too easy - took me quite a bit of work.

one other possibility is to simply get a new tx3max 2/16gb... think i gave u the seller link.

for rm12x or something like that and not 1k, it saves u all the headaches...

it depends what u will use it for.

if u want it for netflix hd, youtube... mibox s is better.

if u want astrogo, unifi playtv, tx3 max is better.

for ahem apps, my bet is on tx3max - regular android less fussy compare to ATV; tx3max has bigger storage.

but u musn't come back and say u want netflix hd!!
