How To Install / Flash Android 4.0.3 ICS On Asus Eee Pad Transformer TF101

This custom ROM has many bugs, with lack of mass storage, no GPS, and no camera function. As such, we advise against installing this custom ROM on your ‘daily runner’ as it were.

Before you start, make sure your Eee Pad TF101 is rooted and that you’ve flashed ClockworkMod Recovery. With the formalities finally aside, let’s get started!
Step 1: Download the following files:

• Android 4.0.3 ICS for Eee Pad TF01 [Direct Link]
• ICS Google Apps [MultiUpload]

Once you’ve downloaded them, transfer them to the /sdcard directory on your device’s internal storage.
Step 2: From ROM Manager, hit Reboot to Recovery to boot your Eee Pad TF101 into ClockworkMod Recovery.
Step 3: From ClockworkMod Recovery, select wipe data / factory reset. Then, in advanced, select wipe Dalvik cache as well as wipe cache.
Step 4: Now it’s time to actually flash the ROM. Navigate to install zip from sdcard > choose zip from sdcard > tf101-ics4.0.3-20120121-cwm.zip.
After that, you’ll need to select flash icygappsv2.zip.
Step 5: On the main menu, select reboot system now.
And that’s it, job done! If all went well, you’ll will boot into (a very early alpha build of) Android 4.0.3 Ice Cream Sandwich on your Eee Pad TF101.
Step 6: Lastly, download and install a CPU control app like SetCPU, No-frills CPU control or Antuantu and set them to interactive governor.
