Post your firmware installed.
Hi @arun7129 , have you ever resolved this? I have tried with 2 usb sticks so far, one (16G usb 2.0) did not do anything at all, second (8G usb 3.0) started the upgrade but it took approx 2mins (not that 5-7 as said in the tcl guide) and then tv booted and its still on V575. Btw TV type 55ud6406. Thnx for any advise here.I am following this steps but not taking update or flash the PKG file...
Firstly I format the pendrive in Fat32 mode... Then unzip the zip file and copied the update.pkg file into Fat32 pendrive. Then tv switched on and keep in standby mode... Then I inserting the pendrive into 2.0 usb port... But after inserting pendrive into 2.0 port tv power button not working.
I tried also with the remove the pendrive and after the power button work quick inserting the pendrive also not work.... Plz. Suggest ... What to do... Currently I am in V575 version.
Did it reset all apps after you installed R820? What pen drive you used please? I am unable to upgrade, it says that message (don't turn your tv bla bla), but after approx 2 mins its done and continues to start the tv ... in about section I still see V575
I missed all apps and reinstalled them.
Thanks, indeed i solved by putting the usb stick into usb 3.0 instead of usb (service) 2.0 .. tbh, the same experience, nothing better compared to previous fw (575), maybe even worse .. and tv still cant passthrough DD+ (which was advertised with tv as DD+ capable) , funny
