I thought it was HBOOT 2.14 that causes the touchscreen issue for AOSP roms?
I used the 2.20 RUU, so your saying if I flashed HBOOT 2.14 I wouldn't have these issues?
The touchscreen firmware is separate from HBOOT but they were both "upgraded" by those JB OTA's so HBOOT version was used an indicator of touchscreen firmware version.
