I have a Navon Platinum Explorer tablet (wich is not an original Navon tablet). Few years ago I was able to clear the dalvik cache, with DDMS in Eclipse (Mars) but it's full again and DDMS doesn't recognize the device, so I can't clear it. Windows says unknown device. I looked for this device in Oracle VM USB device list and there I found it as Onda (unverified) V972 tablet in flashing mode.
When I turn the tablet on it display the android logo and stuck there. When I press the Power + Volume up / Volume down buttons it doesn't display anything, but connects to the PC (or if already connected then disconnects). I can't enter recovery menu.
So how can I clear the dalvik cache, and disable logging so it doesn't get full again?

From Ubuntu

(First, I do not really know linux yet.)
With sudo lshw -short command I get some interesting item related to the device (with H/W path /0/100/6/*):
enter image description here It's maybe possible to do something whith it?

  • Is the device rooted? – Bo Lawson Dec 20 '18 at 19:06
  • @BoLawson I don't rooted this device, but the previous owner maybe. – Noel Nemeth Dec 21 '18 at 14:59
  • I guess the first thing to address would be getting the device recognized by the computer. Try updating the drivers next thing would be try switching between mtp and ptp in settings to see if eclipse can recognize the device. What version of windows are you using? – Bo Lawson Dec 21 '18 at 17:57
  • Windows 10 Pro 64 bit, and see the edit. – Noel Nemeth Dec 21 '18 at 20:21
  • Flashing mode should be the bootloader but I do not know if it uses fastboot commands. Not much can be done to the davlik-cache since it resides in /data/dalvik-cache. However it might be possible to erase the cache which is different. So do you have adb and fastboot installed on your computer? For adb is usb debugging turned on through developer settings? On a side not I am not sure the device is visible to eclipse while in the bootloader. I believe you need to be in the android os or recovery. – Bo Lawson Dec 21 '18 at 21:12
