I managed to use the below old link to go to TWRP but I forgot to download the /e/ zip files to my phone before. So I need to go back and reboot from the system since I don’t know what to do next.
My questions now is the instructions for the manual installation are different between this old link and the new link as below:
So does it mean that I will be able to install it if I follow the instructions for manual installation? Do we need to run the commands for Heimdall?
