Hi friends, I hope some of you can help me. I bought a Tablet in ebay. Since it was running very slowly, I contacted the seller. He sent me that firmware to try it: https://www.dropbox.com/s/yri8f6qc9vhubkz/999-03090313.zip I installed it with PAD v1.07. Now the kernel version is: 3.4.0+ liuzi@gpt-server-sw#106 March 17 2014 Build number: full_gs702c-userdebug 4.2.2 JDQ39 eng.liuzi.20140314.173546 release-keys Model number P706. Now, the touch screen is offset two centimeters, diagonally. So, the Tablet is unusable. I searched for all this site, but I couldn´t find something useful. I tried tscalibration.apk, tscalibration2.apk and touchrecalibrate.apk; none worked. I can´t enter in ADB mode, because there aren´t drivers. I can´t use the keyboard, so I can´t even try something of Google Play. I searched for all the web, but didn´t find a single firmware to try. Another problem, or the same, I don´t know, is that the screen doesn´t rotate. When I try to calibrate from menu>display> accelerometer calibration, there is an error: Gsensor has stopped working. By the way, the seller hasn´t sent me another firmware or solution, in spite of my queries. Could someone help me to find another firmware? I know that fixing the touch would be the easiest, but in these conditions I don´t have the knowledge to do it. Thanks in advance to all.
