[Asus Transformer TF700] NaxIonz:
I thought I would post the steps I did, as a total neophyte, last Friday to Root, ROM and install Data2SD.

They were done on a TF700 that had all the latest ASUS updates, including Jelly Bean (as of November 9th 2012).

The steps outlined are excessively verbose on purpose. They are intended for the most novice of people to the ROM'ing process. I found during my learning process that all the info is indeed on these forums, but scattered, and there are some steps that assume you already know something or are somewhat familiar with certain tasks.

I wasn't.

They are also for doing CleanROM + Data2SD (Clemsynkernel version), but you could swap in another ROM and exclude the Data2SD steps if you want (but its too cool not to use!)

-------------------------------------------------------------------------------------

On your PC:

Download ASUS unlock APK

Download latest CleanROM zip || http://www.scottsroms.com/downloads.php?do=cat&id=53

Download latest Clemsynkernel data2sd zip

Download the partitioning .iso GParted

Download and install ImgBurn

Open ImgBurn and select option "Write Image file to Disk." This will burn the GParted iso to your cd and make it bootable

Config your computer to boot from CD as your first boot device: During the boot sequence hit F2 or w/e F key you need to choose boot source.

Put the CD in then boot up your PC. You PC will boot from the disk and you will see Unix stuff, just leave everything as default (when the prompts show, just hit the enter key). This will boot you to a main screen and it's a GUI so you can take it from here.

Delete whatever is on your SD card already

Create the first partition, I went with 2048 MiB so that there was room for my ROMs that will be flashing. Make it 'Primary' and the label field doesn't matter.

Create the second partition, which will be the remainder of the space. Make it 'Primary' and the label field doesn't matter.

Confirm the changes and wait for it to process.

Once you have the partitioned SD card, put it back to your TF700 with USB connected, your PC will see the fat partition, you need to copy all of the zip file to here so you can install them later on.(ASUS Unlock APK, CleanRom, data2sd)

Put your Unlock APK, CleanROM zip, and clemsynkernel-data2sd zip on your *normal* SD and have that normal SD in your device.

Now, on the TF700:

Opend unlock APK

Agreed to all the stuff

How to Root:

Download CWM recovery from http://www.mediafire.com/?ju5p2p9adpuus2k

Download SuperSU from http://download.chainfire.eu/267/SuperSU/CWM-SuperSU-v0.97.zip

Extract the fastboot.zip into a folder and also copy the CWM recovery img inside the fastboot folder

Attach your device to the PC and copy the SuperSU file in the device

Get into fastboot mode by switching off your device and switching on in bootloader mode (hold power + volume down) and then scrolling with the volume down key and selecting the fastboot option (picture of USB) and then connecting your device to the PC

Now open cmd prompt and travel to the location where you have copied the CWM recovery image inside the fastboot folder

Now give the following commands:

fastboot -i 0x0B05 flash recovery recovery.img

fastboot -i 0x0B05 reboot

Now disconnect your device form the PC and reboot into recovery mode (hold power + volume down, then choose RCK)

Once in recovery mode, choose "Install zip from sdcard" and navigate to your SuperSU .zip file

Reboot the device

Your device is now rooted

Go to the Play Store and install GooManager

Open GooManager

Give Super User access to GooManager

In the top right, there are 3 squares, this is the menu - click to open

Select 'Install OpenRecoveryScript'

Confirm the selection

Opens a window, and you wait a few seconds, then it downloads

It will install and the device will reboot

After the reboot, open GooManager back up

In TWRP, click 'Install' and choose clemsynkernel-data2sd.zip

Select Wipe Cache / Dalvik

Go back to main menu

Choose Reboot-> *Power off*

Take out the normal SD

Put in the partitioned SD

Boot device backup.

If you received messages like " fail to uncrypt data' don't panic, something is wrong with your new data2sd card. Try to reformat and do your card again. Make sure the partition 2 is for your ext4 and it's a primary partition and set to active (boot) set with GParted.
