[Xoom Android Development] scsa20:
I'm going to nitpick this as a person who've done this a few times over (but honestly, not too bad of a guide).

Although the Tiamat ROM is awesome, this guide is supposed to be for rooting only from what I can see and so pointing out to download 2.2.2 (not knowing if the user is really on the LTE version which 2.2.2 won't do they'll need 2.3.0). Sticking to just rooting is best and talk about the varies of ROMs as an extra if that's something they wish to proceed with.

I think you mean "XOOM" and not "ZOOM" :p

hmm.... what? Thinking of this from a "newb" standpoint, this step doesn't make sense. In fact, how do we even get to this first step?

lol wat? For starters, you can't simply "paste" in a command prompt. If a newb has never used the command prompt, they'll be wondering how to paste, so might want to better explain how (right click and choose paste or click the little C:\ icon on the top left, go to Edit, choose Paste).

What exactly are you trying to have us achieve here?

That came out of left field when the last step said to just type adb without anything else... oh, wait, you want us to type adb reboot recovery, is that right? gez, you should of made yourself clear on that.

I lump those both into 1 because they don't actually explain what's going on. What you need to do is press the volume down key to change the selection the volume up to select the selection then repeat

You should already be in a command prompt, if not, reopen.

Don't you mean adb and not fastboot? You can't use fastboot if you're not in the bootloader you know.

I have yet to see anyone having to do this tbh

This steps is all so wrong, plus the link's broken (http://xdaforums.com/showthread.php?t=1242241 is the real link btw).

Simply flashing the recovery from the Universal Xoom Root won't get you rooted, the proper steps is as follows:

1) Boot into the bootloader (adb reboot bootloader)

2) Flash the recovery to the recovery partition (fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img)

3) Once recovery is flashed, reboot (fastboot reboot)

4) When you get the M logo for the reboot, start pressing the volume down key until you get the option that says Recovery and press the volume up key

5) Flash the zip file containing the root files (choose "Install ZIP from SDCARD" then "Choose ZIP from SDCARD", from there, find the zip file that has the root files that you downloaded from the link posted just above)

I'm not going to touch the restoring to stock, I think I made my point that you should clean up your posts and maybe even checked it (or had someone checked it) before posting it?

(yes, I know I was hard on you but someone gotta do it)

So, yeah, looking over this, it's not really that great of a guide at all because you don't really have anything explained and just have more questions....

And to answer luyenbichta's question, the system.img image will take you out of custom kernel and rom and put you back to stock, once you flash all the images needed you can then issue the fastboot oem lock. Issuing that commend before you have the original images back on will caused you to get an error about the images not being signed, no harm, no foul.
