You can do it by copying a stock blob to the staging partition. The TF will do all the flashing for you

You do need adb and root, but no power buttons.

Here's the 1 click method!

Be sure ADB is installed on your PC. There are threads on how to do this all over XDA.

Be sure your battery is charged.

Download a stock firmware from the ASUS website. Be sure to match your country code (WW, TW, US, etc.)

Unzip the firmware. It should create an ASUS/Update/some.zip. Unzip the some.zip file too.
If this went well you should be looking at a giant blob! ~500M or so. No kidding- the file will be called "blob"

Use ADB to push the blob to your TF or just copy it to your SD card. Your choice.

Code:
adb push blob /data/local/
Connect your TF to your PC and type "adb shell" to start a shell.

Type these commands into the shell
Now the magic happens....
Code:
su
dd if=/data/local/blob of=/dev/block/mmcblk0p4
reboot
Be sure to get the dd command correct. The last three characters are zero-pee-four. If you pushed/saved the blob somewhere else, you'll have to adjust the "if=" to match the path.

Your TF should reboot and it will flash the stock rom. You'll see a blue progress bar that will flash quickly, but still take longer than you think it should. Be patient. Your TF will reboot automatically.

You can now delete the blob file from your TF.

So this can be used as a way to return a tablet to stock or potentially un-softbrick a tablet?

This will flash the stock firmware in the blob. If you are softbricked, it might work if you can get to adb.

Is there any mode that adb does work on? (From Clockwork, APX mode(?), etc.)

You might try using the dock?

I'm not sure if i can actually select anything with the dock(like using the power button), but if i boot into cwm with the dock connected i can use the arrow keys to scroll up and down. Worth a look anyway.

If it's enabled, you can use adb in the regular system and recovery. It won't work in apx mode/nvflash.

The tricky part is that sometimes, it's not enabled, and that time is usually when you need it to be. You can enable through the system settings or by changing flags in the boot or recovery images.
