I'm hoping someone can help me with the problem I have. I have a MX2 Android TV Box and flashed it with Matricom firmware, running 4.2.2. When I try to access the SD card in recovery mode it doesn't allow me to do this - Apply from EXT, update from SD card, then it's blank. I've formatted several times and confirmed the files are there but they don't show in recovery. When I open Winzip/File manager on the box I can see my files there. I want to flash the box again but can't from SD because the files won't show. I'm not sure what to do with 'Update from ADB', (is this an option)?.

I don't have a lot of knowledge with these things but want to learn if someone can help me. Thanks

Sideloading (usually seen as apply update from ADB) is a form of adb push wherein the ZIP file, say ROM.zip, will automatically get flashed by the recovery once ADB finishes copying it to the phone. The command you use on the PC is

adb sideload <file.zip>

Chances are if you're using a stock recovery (see if it says 3e at the top of the recovery screen), only official ZIPs from the manufacturer will get through verification; whereas third-party ZIPs will stall at Installation aborted.

But if you're using CWM (or another custom recovery), you can pretty much sideload anything you want.

  • Thanks for your reply. It does say 3e at the top of the screen.. Guess I should download CWM first then. Any reason why the sd card won't work in recovery? – user61388 May 24 '14 at 13:03
  • I'm not sure about that myself, because I've seen the same behaviour on my brother's phone. Maybe it only sees specifically named zips? – dantis May 24 '14 at 13:08
  • @user61388 Wait, do you by any chance have your ZIPs on an external SD? A Google search told me that 3e does not mount external SDs – dantis May 24 '14 at 13:10
  • Yes. I copied my .zip file onto it from the laptop and plugged it in the side. Sounds like that's the problem then. Any other way I can flash the firmware in recovery apart from External SD? – user61388 May 24 '14 at 13:55
  • I should add the .zip file I'm trying to flash I have used on the box before so I know it does work... not too familiar with adb but will use that if that's an option? – user61388 May 24 '14 at 14:04
  • That is an option :D Connect it via USB, wait for the drivers to get installed, then adb sideload away! – dantis May 24 '14 at 23:51
  • I connected the box to my laptop and nothing was detected. Device manager didn't find the box either. – user61388 May 25 '14 at 15:59
  • Make sure you're actually in the sideloading mode before connecting it to the PC. Use the original cable, switch ports if necessary. – dantis May 26 '14 at 04:05
