The digitizer part number is written on the digitizer's cable. If you have the wrong version, then you can update the digitizers firmware. These are the instructions from xda forums: 2. Root your device 2. Get the firmware https://github.com/dasunsrule32/prop...0... 3. Get it into the device: adb push 02-3011-4820.ekt /data/local/tmp 4. Get yourself into the device: adb shell su 5. Delete touch firmware. After firmware update and reboot the device may update the firmware back to whatever is in the firmware folder which is the wrong firmware. It will kill the ic ability to update the firmware again. <---HELP NEEDED In the shell: rm /system/etc/firmware/touch *.etk 6. Update firmware: touch_fw_update -u /data/local/tmp/02-3011-4820.ekt I used Kingo to get root on mine.
The part of the instructions that are a problem is testing with drops of water - The case of the phone might catch these drops and allow them inside the phone. Just don’t test it with drops of water and you’ll be fine.
I must say I don’t mind the tri-point screws. At these sizes, phillips screws are a real pain - like they aren’t at any size, think on - dropping to just three wings gives the screw a bit more meat.
But then again, I have a similar argument for pentalobe - that screw size is too small for torx or hex, Phillips is bad and wrong - pentalobe makes a nice, solid joint between screw and driver.
