Since we want to calibrate the touch screen on Windows 10, we’re only concerned with the Display tab. Click the Calibrate button on this tab. A second window will open asking you if you want to calibrate a touch input device or a pen input device. Select the Touch Input option.
After reading the TF300 topic about flashing the firmware of the PCB I maybe found a solution for the ME301T In the dir /system/etc/firmware/touch I've found the following versions: 0b-00-0009.ekt 0b-01-0009.ekt 0b-03-0006.ekt Tried all three versions and they all show me a different version in the about tab and all change in a different way how the digitizer reacts, but I still haven't the right one. One does everything in the opposite way, the other doesn't react and another only reacts on 1/2 of the screen. So does anyone have other versions?

You need the PCB to get stuck in bootloader mode, when the firmware is reflashed, the PCB looses the calibration data. There are two ways to achieve it: 1. Revtor ncs expert profile download free apps. The easy way: -After digitizer replacement DO NOT connect the digitizer flex cable. -Turn the device on and be ready do disconnect the battery. When the device boots the PCB will notice 'a change' in the digitizer and will try to reflash the firmware. You will see on the screen 'updating touch firmware' or something similar. -As soon you see the percentage gets HIGHER THAN ZERO pull the battery out. 
-Connect the digitizer flex. -Turn the tablet on. Same as before, when the device boots the PCB will notice 'a change' in the digitizer and will try to reflash the firmware. This time, let it finish the process.
-You'll get a perfectly working touchscreen Sometimes the device will not start the updating process by itself. Try to connect/remove the flex cable and reboot.
If the firmware update process doesn't start by itself move to the second method. The hard way -You need to root the device.
-You need to flash the firmware same method as TF300. Adb shell su touch_fw_update -u /system/etc/firmware/touch/0b-00-0009.ekt -You need to brake the updating process as soon the PCB gets to bootloader mode. When you hit 'Enter' you'll see some rows with PCB data and then numbered packets are sent. -When the first packet is sent you'll see the progress dots '.........
', hit 'Control+C' as soon you see it. -Reboot the device.
-If the device won't update the firmware by itself during boot, repeat the flashing process manually but let the update process to finish this time. Enjoy Vadim Brook. I'd like to thank Vadimbrk, solved my issue too. Just to summarize if someone runs to a similar troubles: ME301T, broken glass, replaced with the same type (5280N FPC-1 REV.4), but after that, the touch screen looked like having very low sensitivity, sometimes not responding to touches, loosing touch when dragging, etc.
Practically useless. I have checked all connectors number of times, disconnected display, swithed off wifi, if it could me an EMC issue, no luck. Not sure why, but the firmware re-flash helped! I wonder if it was that the firmware reflash invoked some autocalibration. No idea, but it works Just exactly as Vadimbrk described (the easy way) I let the digitizer firmware re-flashed and the touch screen (digitizer) started working like charm.
Thanks again!
Click to expand.sweeet! I didn't think my screen was that far off, but this worked wonders. Here is a much easier way to do it if you have Astro: 1. Open Astro and navigate to the root of your internal SDcard 2. Click 'multi' in the toolbar, then click 'zip' 3. Enter the name as Calibration.ini 4. Long press the.zip file you just created, click edit -> rename -> then delete '.zip' from the file name to make it 'calibration.ini' instead of 'calibration.ini.zip' and click ok.
