You have the USB debugging enable or have you had to enable it?
Have you tried installing differen ...

It was enabled by default in the new firmware, although before that I took the same steps as you did for the old firmware (before upgrading to the new one, unfortunately I had no lcd screen back then so cannot verify the key). Now I have the lcd screen but problem with the adb. I tried the ADB installer but it did not recognize the phone. I will try a few different things & will let you know the results.

Thanks for the reply batojay.  
I accomplished update the android image (I tried to press the power button before connecting the otg cable and it worked) but now has the same problem which i mentioned earlier
Apparently the update does not completely replace the android system and the problem persist.
Of the TTL debug pins i get the following:

I have been reading and apparently it goes into suspend loop.
For now, i must resolve this problem (no idea how) before continuing.
I wait for your comments and i hope you succeed with the adb.

I made it!
This post helped me to stop the suspend loop: http://forum.legato.io/t/suspend ... uspend-to-debug/251
Then, combining the last post for enable adb, and this: https://forum.xda-developers.com/showthread.php?t=893434
I do not why this time dont request me to verify the key and after a reboot all work fine, and automatically opened the vysor and i see the screen.
Finally i won, and i'm so happy that don't know what do now

Hi gtrangoni,

I also experience the console freeze, but dont know what to do , since in the GUI mode using LCD screen all works fine. It is great that you have resolved the problem. I will try your solution when I get the time.

Thanks....

I finally able to use ADB using this command:

1. setprop persist.sys.usb.config "adb"

Congrats batojay! Enjoy it now. Is the beginning for do something more, i guess.
Yes i saw that command. Another useful is "svc" command. With this you can control power, wifi, data and usb.
For example:
svc usb getFunction -> gets list of currently enabled functions on device

Thanks gtrangoni. Well, for starter, I have managed to toggle some io pins on & off from adb terminal if you are interested.

I found solution for unauthorized device in adb:
Copy file from %USERPROFILE%\.android\adbkey.pub to folder /data/misc/adb
Rename file /data/misc/adb/adbkey.pub to adb_keys
This could be done easily by mounting device in mtp mode:

1. svc usb setFunction adb,mtp

Copy code

copying key file into phone storage and in console:

1. cp /mnt/sdcard/adbkey.pub /data/misc/adb/adb_keys

Copy code
