ZE500CL TW SKU Firmware Needed

I bought a second handed ZE500CL TW SKU phone, but I have a problem, everytime I restart the phone it display touchpad firmware update with 0% progress (after waiting 12 hours still 0%).

I searched to fix my phone, and realized that my software version is WW while my SKU version is TW. Someone said in this forum that WW and TW LCD IC are different.
So, I need to install the right firmware which is TW version, but I couldnt find any TW version.

Every site I visited only have firmware for WW SKU only. So, pls help me find firmware for TW SKU.

Thank you.
