Got my bootloader unlocked, trying to boot into TWRP but hit a speedbump?

So I got my bootloader unlocked so obviously fastboot drivers are working, I have the SU zip copied to my internal storage and the IMG file in my Minimal Fastboot folder location....

When I run :

fastboot boot "path to IMG".img

My command prompt just says "waiting for devices" and does nothing?

Do I run this command from while in bootloader mode? Power + Vol down ? When I have it plugged into my PC in this mode and I run "adb devices" it does't find my device? Does that mean I don't have the right drivers installed?

What am I missing here? Damn this phone is complicated.

You want fastboot boot twrp.img
Then you want to install TWRP rc1 from your internal storage from TWRP. Then you want to boot to system once then boot to recovery and install su2.79 sr3 from your internal storage
You want to be in bootloader mode/fastboot for the first step

If you already have TWRP rc1 installed then you just want to boot to recovery and install su2.79sr3
In fastboot type in fastboot devices and if it comes back with your device number your good to go

I know the command I want, I'm asking where I run it from? Do i run it while my phone is in Android connected to my PC or do I run the command from fastboot while my phone is in the bootloader mode??? When I have my phone connected normally and run an "adb devices" it doesn't find my phone but obviously it recognizes my phone otherwise it wouldn't have been able to copy dePixel8 and unlock my bootloader.

My question is *where* do I run that command. As I said before, if I run it while my phone is powered up normally and connected to my PC it just says "waiting for devices". If I power my phone up into bootloader mode (power + vol up) my fastboot doesn't see my phone????

I guess what I am saying is how the heck do I boot into the TWRP IMG ? My bootloader is definitely unlocked, I have SU on my internal storage, I have the IMG in my minimal fastboot folder. I just need to know how the heck to boot into "recovery mode" using the :

fastboot boot "path to".img

If I run that command while my phone is connected normally with USB debugging enabled it just says "waiting for devices"

Am I missing something here...?

Run the command with your phone in bootloader mode and your computer in fastboot

First off get rid of minimal. That is not your current problem, but you will have problems later. It is old, it doesn't know about our partitions or handle their larger size. Get googles

Put the TWRP img in the same folder, skip the path

Fastboot BOOT {twrpfilename.img}

You need to follow the steps I gave you. You need su2.79 , and rc1 on your internal storage. Then you need TWRP rc1 boot image on your computer. Put it in your platform tools folder or wherever you got your other firmware. Put phone in bootloader mode, then open a command window where you have TWRP boot image saved , type in fastboot devices, to make sure computer is seeing the phone, then the command should be fastboot boot TWRP.img, then install rc1 off your phone storage, then boot to system once, then boot back to recovery and install su 2.79 sr3

OK I figured it out, while the phone is booted into Android you have to actually issue the command to reboot it into the bootloader mode otherwise it won't detect the phone (at least it wouldn't on my PC)

I ran this command from my minimal fastboot folder (shift + right click -> open command prompt)

I then typed this:

adb reboot bootloader

Then once it is rebooted into bootloader mode issue the

fastboot boot .img command

It then rebooted into TWRP, and I was able to flash the SU zip

Sorry for bugging everyone, this phone is a Pain in my....but it's damn fast and damn nice!

Thanks man, I figure other people might run into these problems so I might as well post about them. If I booted directly into the bootloader my PC wouldn't recognize the phone, if I issued the command to reboot it would. Weird...but whatever, I'm unlocked and rooted....

THANK YOU!
