Per l'accensione non so che dirti; per il firmware e per i problemi di boot io ho risolto seguendo questa guida; adesso l unico problema che ho e' che ora funziona solo su televisori 720p. Sui 1080p non va. Non so che fare...Proverò a cambiare cavo.
Ma non esiste un firmware per il 1080p MK808B? Ginopaneg sicuramente tu lo sai...
Guida allegata a firmware 1.5 finless
To get the drivers installed we must FIRST put the mk808 into ROM flash mode!
So I am going to explain how to get the unit into flash mode.
To put the mk808 into flash mode the easy way:
1) Remove any SDcard you may have installed.
2) Connected the supplied USB cable from the device OTG port to your PC.
It will power up and windows may detect the device. DO not worry about that. We need it powered up.
3) In the ROM kit run the ROM FLash Tool.exe.
4) YOu should see at the bottom it says "Found RKAndroid Mass Storage USB"
If it does not say that go into settings and make sure that
a) USB storage is turned off
b) Under developer options, USB debugging is turned off
5) Once it says "Found RKAndroid Mass Storage Usb" in the flash tool click the "Reboot to Flash Mode" button.
6) Wait up to at least 10 seconds. The unit should reboot and the screen for the mk808 will be black (no ouptut).
7) If the unit does not reboot to a blank screen, repeats steps above
Congrats! You are now in flash mode! To get out of it at any time just unplug the USB power to the mk808.
It will boot back up normally out of flash mode.
If you do not ever see the flash tool say "Found RKAndroid MASS Storage USB"
Or reboot to flash mode does not work, then use this manual proceedure.
1) Have the USB cable unplugged.
2) Near the HDMI port are 2 holes in each corner. One is the blue LED hole.
The other in the corner is a reset button under the hole.
Use a paper clip or something to push the reset button in this hole.
I actually enlarged the hole so a paper clip would fit.
You will feel the button "click" when you are on it.
3) Hold this button down and while holding it, plug the USB cable from the PC to the OTG port on the MK808.
4) YOu should here windows BONG it found a new device. The LED will not light!
5) You are now in ROM flash mode. Read below for installing drivers.
Driver install:
1) Now that we are in ROM flash mode as above, Windows should now have a new device found and it will be unknown.
2) Open the device manager in control panel. You should see a device listed as unknown with a yellow symbol in it.
3) RIGHT click on it and select "Update Driver".
4) You will get a dialog asking to search or browse my computer for the driver. Click Browse
5) On the next screen click the browse button. A file manager will open.
6) Now remember I told you to unzip this package to somewhere you know how to find it like the desktop?
7) Using the file manager point to this package, Click on the driver folder.
8) Then click on the folder for 32bit or 64bit depending on your OS.
9) Now click on your OS version, e.g. Win7, etc.
10) The OK button should now be available to click OK.
11) At this point the drivers should install. If not start over.
12) No matter what, reboot the PC now. Also unplug the mk808 and let it reboot
13) Once the PC is back up plug in the mk808 and repeat the steps for getting into flash mode!
14) Now this is important! If you did everything right when you go into flash mode (blank screen),
the PC FLash tool should now say at the bottom "Found RKAndroid Loader Rock Usb"
If it does not, you did not get the drivers installed! repeat above yet again.
Flashing the ROM:
OK so you know how to get into flash mode AND you got the drivers installed.
The flash tool says at the bottom "Found RKAndroid Loader Rock Usb". We are ready!
NOTE THIS WILL ERASE THE UNIT AND REMOVE ANY APP, MOVIES, WETC you may have put on it!
THis is a full erase! However to get the 1gig of APP space, WE MUST DO THIS.
So make sure anything you had was backed up.
1) DO NOT UNCHECK OR CHECK ANY OF THE BOXES IN THE ROM TOOL WINDOW! I have set this up to work just right!
If you uncheck or check something.... YOUR ON YOUR OWN IF YOU BRICK!!!!!
1) Press the button in the flash tool "Erase NAND (IDB)". Let it finish.
YOU MUST DO THIS OR THE FLASH WILL NOT WORK!!!!!
2) Press the "Flash ROM" button. It will take several minutes to do it's thing. Watch for errors!
3) After flash and no errors, the mk808 will reboot.
Notes:
If you got errors using the PC flash tool, then you have some kind of USB problem.
Some things to check:
1) Make sure you connect to a real USB port from the PC. NOT a USB hub or maybe even front panel USB ports!
2) Some older BIOS have a setting called "high speed USB". You may have to go into the BIOS and turn that off.
That was a crappy implementation of USB 3.0 that is not reliable.
3) Try connecting to USB 2.0 ports instead of 3.0 if you have them.
4) Try unplugging any other USB devices like removable disks, hubs, media readers, etc.
5) All else fails, try another PC.
