Hello everyone from Russia! I'm from the forum 4PDA. I do not own UMAX85, but I use another model of this company Super TV x4-50 pro with Mstar938. However, I follow the models of this company. Today I managed to get native Chinese firmware for your model in BIN format. LetvUpgrade938_4G.bin. This is the latest native firmware version in this format (080S). Now you will have fewer problems with the restoration of bricks and the minimum time to completely reinstall the system. I was looking for this firmware in your topic header, but I did not find it. On this I post a link for download.
The file was received directly from LeEco using the uMax85 TV's MAC address. Thanks
for MAC. Now you can easily restore your TV via mboot.
I do not have 5 posts in this forum yet and I cannot post links. I sent the download link to
. He will publish the link when he can.
Our models are very similar.
We can get the root through custom recovery or directly using USB3.0-UART or VGA-UART. Made a custom rom for everything at once. We learned how to remove all Chinese trash, remove start ads, replace bootanimation, and also replace the start video with a beautiful one. We can also change the embedded start image. learned how to run digital television (DVB-T2) using the built-in TV tuner. We have a NXP TDA18275 tuner. install gapps. And use the Google assistant using an external microphone for 2 dollars from aliexpress. Well and some other nice things. If you need information, ask, I will try to answer.
If you already know all this, then I apologize for my carelessness to the head of the forum. I will be glad to answer your questions and ready to share knowledge.
