Here is the 3.1 update.zip for the Transformer.
File removed per ASUS' request - Phil
Extract EP101_SDUPDATE.zip from the above .tar file
Place it on your SD card
Make sure the Transformer is plugged in or has at least a 50% battery charge.
Press the volume down key and power key at the same time and continue to depress both until you notice a ROM Boot screen that advises you to press the volume up key within 5 seconds to start the ROM update process.
Press the volume up key and the unit will update and reboot. It should take about 3~5 minutes
After a reboot, a user notification should arrive in five minutes or so that the docking station has a firmware update available to version 0209. Please follow the instructions and update the docking station and then complete another reboot. The 0209 firmware offers improved typing speeds, mouse tracking and USB compatibility.
Do I have to place this on a SD card or can I just put it on the internal storage?
You'll need to put it on an SD card. When the device reboots it won't have access to the internet. And remember, you're sideloading the update, so you can't use the normal "install from internal memory option."
The update is pretty small. a 1 gig card would do. I used my old 2gb from my old feature phone.
Hi! Noob question.
Im in sweden and have the HRI66.WW_epad.18.104.22.168. Can i use this update too?
im also on the ww-firmware. if you put a folder on MicroSD named ASUS and inside another one Named Update and put the update in with the following name: WW_epad-user-22.214.171.124.zip - then remove the microsd card and put it back in your tablet -> your tablet will recognize it and show the exclamation mark. but i'm too scared ^^
