Amazon Fire TV Stick 4K (E9L29Y) TWRP Unlock Issues/Help

[itsmidnightyo]

Hey everyone!

I ordered an Amazon Fire TV Stick 4K (E9L29Y) the other day to replace my older Fire device as it's been showing its age; however, when it was delivered that morning and I woke up and checked for the package, it wasn't there. I immediately ran to Amazon support to explain the situation and they ended up refunding me. Before this, I asked one of my roommates if they took the package inside by chance and they said they didn't, but I later confronted them again and they put it on the table. Crazy, right? So it didn't cross my mind that this device would now become unusable since it was refunded and I've learned that it's been marked as "lost/stolen" by Amazon and cannot be setup. I realized this when I connected it to my TV and can't get past the initial update screen.

So, now I'm learning that it can be rooted and bypassed with TWRP using this guide here which I follow.

I install FireISO onto a USB and get Kamakiri copied over and I run the .sh script and get it to the point where it's waiting for me to connect the stick with the pin shorted (I used aluminum foil). I've tried this multiple times even readjusting where I short the pin. Every time I think I'm doing it correctly, I get this error:

serial protocol mismatch expected 0000 got 2001

Is there anything I should be doing differently or am I out of luck?

Is 4K unused?
If so, you can take it out of the box, connect it to your PC immediately, and install TWRP with "FIREISO" and "kamakiri". (Short not required in most cases)
If you have connected to the TV and connected to the Internet before installing TWRP, it may have been updated and you may not be able to install TWRP.
As long as you can install TWRP, even if it is blacklisted, you can use it by deleting /system/priv-app/com.amazon.tv.oobe in TWRP.

I connected it to the TV and I assume it updated already hence the error. When it was bought, I had it set to already connect to the internet and link to my Amazon account.
