This may be a long reply but may be of help to someone. I have a DroidBox T8 V 2.0 which I have turned into a MX3 4K box. At age 68 I am a novice at this and someone sharper than me may wish to produce a You Tube Video of how to do it. The DroidBox was given to me, I powered it up, got a constant whirling on the home screen, I just didn't like the look of it, and all links looked to be dead. How do I change it. This is where the old adage comes in if you don't know what you are doing leave well alone. Well I didn't. Was booting something up, didn't know what I was doing got stuck in boot mode and turned it off. BRICKED. Started to do some research, opened the box up looked at how to short the pins out on the nand chip, got some sparks, put it back together, still bricked. Did some more reading. Now in the steps I will give you, the more technical of you will understand what I did. Here goes. I got some firmware off this site, put it on a normal SD card in unzipped form and did the reset button power method. I couldn't believe it the box rebooted and I was back in business. I still didn't like the format, and just how easy it was to press a tile and it went back into boot mode and I was back with a brick. Got the SD card out again and got it back working. Did some more reading. Went on the Entertainment Box site they had some fireware. I put it on a SD card in unzipped form and ran it with reset button power method it worked. Everything was blue I didn't like it. Did some more reading. Got the idea that the Droidbox was running S802 with Mali 450. Surely if I get the firmware from another box that has the same guts then it should work. Looked at China Gadgets. Saw that MX3 4K had the same innards, brill tried to download the software, had to jump through so many hoops. Used the USB tool to load the firmware image, got parsing error, just would not work. Loads of questions about this problem, why don't they work, cos the files are corrupt. Now this is where I had some luck. You too will find this I went onto TRONMART . CO and using cut and paste downloaded all the files for the MX3 4K box, no hoops to jump through they came down fast.
Now loaded up the USB tool, with the 115k4 image, I couldn't believe it, every worked, booted up the box, it was now MX3 4k There is always a problem the remote would not work . Did some more reading, and viewed a video on You Tube about MXQ boxes, after firmware upgrade, remote not working. Something about how to get remote config files. He showed a root tool to do this, of course I downloaded the latest version and couldn't understand how to use it. So I went on the web and downloaded an older version of the software similar to his. Don't waste your time downloading the 4 remote config files that he points to cos they do not work (they are for a different box) I got the remote to work. This is how I did it. I rebooted the Droidbox with it's original firmware, and extracted the remote config file by cutting and paste it to a SD card. Then I rebooted the Tronsmart 115k4 back onto the Droidbox. Using the root tool I extracted the remote config file onto a SD card renaming it, so if I wanted I could put it back. Then I replaced the file with the one from the Droidbox, held my breath booted it up, and hey presto it worked. The original Droidbox remote now works with MX3 4k. I can't say I like the look of the Droidbox remote. So I have been on e-bay and have ordered a MX3 4K remote, I will just put back the tronmart remote config.file. Of course I have loaded Kodi from Mygica media centre 17.1. and everything now works as it should. I hope you can all follow this lot, this was all done by trial and error and by thinking outside the box, I haven't the way with all or brains to produce a You Tube video of how to do all this.
If there's anybody out there who can do this feel free. It would be nice if you gave me a mention.
If you lose remote functions when first installing 115k4 you can get by, by using a wireless mouse. Or buying a universal android tv box remote which on the back has a useful keyboard.
On your original Droidbox if you lost your ability to mount firmware by the reset button /sd card method, if the 115k4 firmware install by usb method works for you, it will give you back the reset button /sd card method. which will give you two strings to your bow. bye
