So, this way it's hard to solve your problem. You need to get a USB cable to connect it and then you can reinstall Stock ROM.

If the touch screen of your phone cannot work without experiencing any physical damage, it is probably caused by software issues. In this case, there are several means you can try to fix the issue.
1. Restart the device
When an error occurs on your phone, the most direct but simplest way to settle the problem is restarting the device. That's because this means can stop all the running applications on your phone which can release the device from heavy load. And the operation is very easy- press down the Power button until the screen gets dark. Then wait a minute and hold down the Power button once again to start the phone.
This way can turn your phone back to normal status at most time.
2. Take out SD card & SIM card
Sometimes the SD card or SIM card on your phone would cause some issues as well. Thus, you can try to:
- Turn off the mobile phone and then remove the back cover of the device to take out the memory and SIM card.
- After that, you can reboot the device and check if the screen is responsive now.
3. Inspect whether there is malware or incompatible application on your phone
Malware or incompatible applications on your phone could affect the phone running as well. Hence, you can boot your phone into Safe mode to see if it runs well in this mode. If it does, you need to delete or uninstall the programs that you have installed on the device recently. Here, to enter the Safe mode on Android phone, you have 2 means:
- Switch off the Android phone and long press the Power button to reboot the phone. Then release the Power button when you see the brand logo of your phone. But immediately, you need to press and hold the Volume Down button until you see a Safe mode indicator at the bottom left corner.
- Press down the Power button until an options menu shows up. Just long press the Power off option and you will gain a message asks you whether to reboot the device into Safe mode. Just tap on OK.
Then try to factory reset.

The Android screen might become unresponsive due to physical damage. When the screen is crashed badly, the only solution to settle the problem is to use a new screen. But if it is just damaged slightly, you can try some free tips first.
1. Test the phone screen
You can check whether the phone screen is available via a diagnostics test at first. To inspect that, you need to:
- Open the phone dial and then enter the specific code to bring the diagnostics tool menu.
Notice: Different Android models have different codes. For example, the code "#7353#" can be used in most Android smartphones, Motorola device users need to dial "#0*#", etc.
- Next, select TSP Dot Mode or TSP Grid Mode to test the touch screen. If you choose TSP Dot Mode here, there will be small dots on the screen when you tap on it. But if you elect TSP Grid Mode, you can test every spot of the screen in grid overlay.
2. Knock the touch screen
Another useful tip to fix the issue is to knock the touch screen. It sounds like a child's play but this means is tested by many users already. So you can try to knock on every corner of the touch screen gently for a few times. This would help to connect the digitizer cable to the device tightly.
Hope it's useful.
