      Instructions firmware: 
      1. Unpack the contents of the archive to your external SD-card in your phone. Extract "download.ldr"in the root of the card. (/mnt/sdcard)
      2. Unplug USB cable, disable Wi-Fi, Bluetooth autorotate, GPS etc and put your phone in airplane mode. And then set the screen timeout to 5 minutes or more. 
      3. Go to Settings –Display –at the bottom –update software touch screen.
      4. DO NOT touch the screen. Wait patiently until the whole updated is done. (Blue line) if correct it will update version 13 to version 25. 
      5. Now reboot your phone and then calibrate the screen, go to Settings –Display -. Put the phone on a table or completely flat surface and click "calibrate". Again DO NOT toch the screen until the end of the calibration.
      6. From the root of SD-card delete the file "download.ldr". 

      WARNING. Updating the firmware touch screen is a dangerous procedure. All at your own risk. If you don't undertand don't upgrade.
