I followed this thread. My point in posting my experience was that *IT APPEARS* I didn't need to flash the ROM... I just used command "fastboot boot boot.img" and it did its thing. Idk what happened to make that happen but how I read the OP guide it doesn't seem it means to work like that.

So what I did. I have ADB/Fastboot setup in a folder on my C: drive. I put the extracted boot.img from the ROM of my choice into that folder and hooked up my phone to my laptop.
I then booted into Fastboot mode and used the Fastboot command as described in OP. After that my phone went into "Know-it-all" mode and just booted up the ROM.


If I need to clarify I can as I wrote this from memory.

Just my spare change.

OOOOOPPPPPPPPPS

I was wrong!!!

i forgot the word flash when i kept typing "fastboot boot boot.img"


oops haahaha disregard whatever i said CJ

I see, then you did flash. There was a way with the G1 to boot an entire image or just a kernel or so just by using fastboot commands; it looked like this was how you did it. Got it, then. I do wonder though if the way with the G1 was hardware specific or Android generic...

Basically, recovery does not have the permission to flash the boot image, but fastboot does? Is that the bottom line?

Yes

So, I can confirm this works. My boyfriend recently had his phone stolen, and the insurance replacement had the new hboot on it. He is very new to rooting and roming, and thought he could do things like he did on the old hboot. He restored a back up of bulletproof, and everything was messed up. He was cursing and damning his phone, when in reality it was him not doing his research that caused the problems. He finally in desperation decided to let me fix it. I flashed the kernel through fastboot, and now everything is working peachy keen. Thanks for making me look like an Android god/ bad ass to my newb boyfriend.

WORKED!!! I love this! I unlocked boot loader with all in one kit, but it didnt want to root my phone. So I seen this and said wth. Tried it the first time and it didnt work it just stayed in a boot loop. Well IM guessing thats because the first rom must not have been ICs so i went back and downloaded a rom that I knew was ICS and tried it once more ...It rebooted with the mytouch screen then went to a black screen wTh? Oh no....a second later ALL TYPES OF COLORS YES!! ICS lol and it ROOTED my phone!? I say that becuase i couldnt root before no matter what even having recovery it wouldnt grant SU , but with doing this it rooted , THANK GOSH! lol
THANKS GUYS.

Wow, thank you so much. I was seriously about to give up on this, but I decided to give it one more go and I finally got CM9 on my phone. Still have S-On though.

Not knowing how to use dos is 1 thing.

When in dos and you run a command, the system first look in the folder that you're running the command from for that command, and if it does not find it and it has a list of directories in which to look for the command. This list of directories is called the path variable. What I recommend, is that you find where your fastboot.exe file is, and add the location of that file to your system path variable. If you do not know how to do this, I recommend you try google because it's a common enough thing that the answer should be easy to find.

Alternatively, you can put a copy of the fastboot.exe file in the directory where your flashable image is located and run the command from that directory. The problem with this method, while it works, is that you will need a copy of the fastboot.exe file in whatever directory you run it from every time you run it.
