Hello everyone and thank you
@Rivers for your step by step Tutorial.
I get the exact same error than Billyliem to the step 6/
After the screen "Awaiting Payload" on my PS4, i go back to my pc, adding my IP address with 9020 port, and i get the same error message. I tried with Hen+Mira and Original. Same result. Also in the error popup message, the port isn't 9020 but 9023.
And after the error message i get in red words "Injecting kpayload.elf" under the "Next Scan" tab.
If anyone has a solution and wanna help i'll be really grateful.
Thanks for taking time to read me already.
Cheers
Edit:
I finally got it work. I just restarted my PS4 and did step by step at the beginning of the restarting. It worked without issues.
