Does the script automatically interrupt the uboot timer or is it just for everything after step 6?

The script helps only after the SD is fully booted; well, its a gnu+linux bash script, it doesn't work at boot-up. Interrupting uboot is manual, based on the feedback received on the serial console alone.
Would you see the same output from a monitor if you do not have a serial cable? I am just wondering whether you can get away with that approach.

From the guide

Technically you could try to time it blind, but unless you already know how the boot output over serial looks you are unlikely to get it right.
Sorry, I read it too fast. Thank you.

Yesterday I tried to it blind.
When I removed the jumper 3 seconds after turning on the power, writing the image succeeded.
However, this method may be dangerous. Then I will try to it by using a serial adapter (CP2104) tonight.

Well done. It's definitely not impossible to do, it's just a bit difficult.
Also, welcome to the forums.
Experienced IT guy here, but noob to SBC. I just wanted to make sure I got this right.
Do I need a serial terminal to install Android to the eMMC or just to install linux to the eMMC? (per fire219 on 08-15-2017, 02:05 PM).
If so does the CP2102 module USB to 3.3V TTL referenced in the tutorial require soldering to the rock64?
if so are their guides for it? Thanks for the support.
