[AT&T Samsung Galaxy Note I717] tigerknight:
Figured I would share this just because once I found the right pieces to the puzzle it's gone beautifully. Instruction steps match URL list #'s. I put the downloaded files into my external SD in a folder called 00-CWM so that it always shows up at the top of the listings.

First off, the pieces:

CWM upgrade steps

CM10 download

Google apps package

CM Flash Instructions

Steps:

0 - BACKUP YOUR DATA: Duh. this is a sanity check step really, make sure you've taken efforts to protect anything you want to keep should the worst happen. At the very least do a CWM backup to the external SD card prior to flashing.

1 - Install the appropriate CWM recovery image (AT&T - 'quincyatt' - in this case). This is critical because without it, the CM10 flash step fails with 'error 7'. Root is required to follow the steps at this page, you can go here to find the means to do so if you haven't done it already.

The actual DD command did not match my own file location, so I had to modify it slightly. To figure out where to go for this run the android terminal emulator. The first command you run will be 'su' - you'll get prompted by superuser, hit allow. Next type 'df' (hit enter) and you'll see a list of mounts, mine was something like /mnt/external_sd/ when I did this step - look for something that makes sense, then get over to it via 'cd /path/to/your/external_sd/CWMfolder' (hit enter). Next run 'ls' and make sure you see the recovery-cwm-touch-5.8.4.3-whatever.img file like you're expecting. Now, start typing 'dd if=./' and DO NOT hit enter yet, go to the page mentioned above and copy from the filename all the way to the end of the line and change back to the emulator and paste (long press on the screen, paste), and hit enter. It will take a few seconds and then give an 'ok' with a few lines of output at the end if all goes well. Congrats! you now have CWM for CM10 (btw, grab the TOUCH version, it's free when doing it manually, only updating to it through rom manager costs money).

2 - I grabbed the M2 at that page, but if you click 'nightly' on the top left section you can grab whatever the latest build is.

3 - Strictly speaking you don't need Google apps to boot your phone and have it be useable.. but come on. An Android-based phone without Google apps? Pfft.

4 - The next thing is to get into that new shiny recovery you just installed. Jump straight to the 'flashing cyanogen mode' link on the wiki (hey, item 4 there too!). You can do it the traditional way with the power+vol+home buttons, but since you've got root installed I'd suggest just grabbing 'quick boot' or rom manager from the market and using their methods to go directly to it from your launcher. However you go about it, get to recovery.

Once again, if you haven't done so already: BACKUP YOUR DATA.

Your external SD card should be fine, but these steps tell you flat out to wipe/reset your phone which will nuke all internal memory. I went even farther than part 5 and 6 on this URL and next went to advanced and told it to wipe dalvik cache as well. Considering they don't tell you to it's probably not a mandatory step but in the interest of a totally barebones start, I did it.

Now you get to the moment of truth - flashing that lovely CM10 file. If you've followed me through this it should go nice and easy, though not much scrolling by on the screen to tell you how it's going. It will just say 'installing' for a while and then be done with no particular errors. Next, flash the google apps zip file. You'll get a little more output there but again it should be fine and have no issues.

Once that's done, press back until you see 'reboot phone' and hit it. Now wait while it boots up and enjoy.

ADDITIONAL NOTES ON THE EXPERIENCE:

Why am I writing this? It all seems trivial, right? Yep. Except that for two days straight I couldn't find any information whatsoever on the current release install instructions. Everything was saying to go to CM9, then do this, then do that, etc. Then I found URL #4 and thought 'GREAT!'... until the cwm recovery they link to didn't match the md5 checksum and I had to start digging for that piece independently.

The best part so far has been that after booting up CM10 and putting in my Google credentials, I got told about updates - so I fire up the market and was floored when all of my previously installed apps came flooding in. All 84 of them. Google profile backup was a beautiful thing. It didn't get my settings, so if you did a TiBkp of your stuff you can probably take advantage of it, but this was a huge basic help for me.

CM10 runs well so far and I'm half tempted to leave the trebuchet launcher as primary rather than nova like I'd been on ICS.

All in all it's a positive experience once things got rolling, and I am just trying to help by gathering up bits of info so that others won't go through the headache I did to get to this point.
