[quote name='donaldson;18589]@projectgusI'm not sure I get this.You said at your blog that "at startup' date=' the Eken loads the serial number and compares it with the serial number it calculates from the wireless adapter." But I've done my fair share of hacking these tablets and more that once, believe me, I've started up my eken without the WIFI adapter card connected or turned on, whatever. If there is no WIFI adapter to read the MAC from, wouldn't I have seen the DEMO expired message? Even this morning I was hacking around my M003 with the wifi adapter unplugged using Slatedroid 1.3 firmware and no DEMO expired message. Does the software check bag out if there is no MAC address? Once retrieved, is the MAC address stored somewhere on the tablet? Just wondering at this point.[/QUOTE']Yes! I just read the code again, and if I read it right this time then the check is in a loop waiting to get the MAC address from the 'ra0' interface.If it can't find the interface (ie if your WiFi adapter isn't plugged in) then it just keeps trying. If it also can't find a serial number, then it will put up "DEMO VERSION" but as long as it can find the serial number (which is stored internally) but not the interface then it just keeps checking every 10 seconds and never does anything.So unplugging your Wifi adapter may actually be a way around the problem (I do not know so don't blame me if it doesn't work or does something worse.) Although then you don't have Wifi, which is a bit of a drag. ...I just noticed something else interesting about the 'Phone Home', which is that it looks like if the aiteer-order web site returns a valid serial number then the Eken will accept it, save it internally, and then work properly... So it's possible for someone (Aiteer?) to remotely re-enable these tablets. (At least for 1.7.2, this may have all changed in 1.7.4 noone has decompiled that source.)
