Step 2 seems to KILL the HOME screen. Step 1 is good.
copy from other posts:

I am running PiStar 4.1.0-RC7 on a RPI 3B and have added the 3.5 K series screen connected  by USB/TTL adapter via USB port on RPi, with Mitch's latest nextion TFT file. All seems to be good on the screen except CPU temps.
Using the instructions from Mitch's UPDATING PI-STAR WITH NEXTION SCREEN: STEP 1, the github loads fine and the Update works fine, all is well except no CPU temps.
STEP 2 is executed with the ./IND.sh option 3 then select #2, all loads fine then this is where the problems start:
The HOME screen now is always waiting for data... and is always inactive except the only box works is the LINKS button.
So... once again, format SD card and start over, done this 3 times with 2 different SD cards..... same results.
Any help would be appreciated !
Should I go to the full new Pi-Star_RPi_V4.1.0_26-Mar-2020.zip??
