Just quick format your USB (fat32) Go to the link below and click the link on section 2 to start the download, put it on the USB stick. Switch your TV off on the power button underneath then hold standby on the remote whilst switching the power button back on until you see the firmware flash has started. Make yourself a cuppa and wait 10-15 mins before it completes... simple :smiley:

Did mine tonight and works perfectly.

HDR files look amazing.

The French firmware is the same release as the UK that is currently rolloing out, but I gave up waiting.

Mine is the H50m3300.

​it's actually very good. you have to much about with the settings to get the best picture. I have a Samsung 4k 48 inch im anorher room and it was similar tho not as fiddly to get right. however if you are interested in this TV get over to the m3300 forum on AV forums. it has 25 pages of info and questions about the set.

it really is fantastic for the price.

have this very model and updated it with a French update. it does indeed have hdr. it's fantastic for the price tho I've read a lot of folk complaining about AO. I bought mine from amazon for £525 odd.

Doesnt the tv download the hdr update directly or do you have to install from a usb from another region.

Link or proof please. I cant see any updates for the firmware to enable HDR, Ive also tried OTA and theres nothing there.

It looks great, no it looks f***ing brilliant if I'm honest! :smile:

​thanks for providing link. I've tried to get link but ended up downloading the update to my phone.

​yeah I did the same for the 55 inch m3300. make sure your usb pen drive tho isn't 64gb or above. I had issues with 64gb being read by the TV. but the 32gb was read without a hitch. similar issues were Spoke about on AV forums.

my amp is not 4k.ive got sky q,fire TV and nvidia shield. all plug into my amp.then one HDmi cable comes from my amp to TV.am I correct in thinking if I buy this TV my amp will not be able to be used
