** This is completely unsupported!!!!!!! **ALL credit goes to saurik for the root method, Jason A. Donenfeld (zx2c4) for finding the exploit, alpharevx for finding the offsets and initial confirmation on the Transformer Prime and viperboy for finding it and posting it in his thread. I did not research, find, or develop this root method!Mods, if I've done anything wrong, please feel free to remove this thread.You will need to know how to use ADB commands, otherwise,Downloads:Root:adb push mempodroid /data/localadb push su /data/localadb shellchmod 777 /data/local/mempodroid/data/local/mempodroid 0xd9ec 0xaf47 sh** You should now be in a remote shell session with root (indicated by #)mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system** IF you have previously rooted your Prime, run the following two commands. They may throw an error that the file a file was not found.rm /system/bin/surm /system/xbin/sucat /data/local/su > /system/xbin/suchown 0.0 /system/xbin/suchmod 06755 /system/xbin/surm /data/local/mempodroidrm /data/local/suexitexitadb rebootAfter your Transformer Prime comes up, install Superuser from android market.Enjoi!!!!!!!!!!!!!!!** Feb 21 2012 Edit **Works on 9.4.2.14** Feb 09 2012 Edit **Works on 9.4.2.13** Jan 25 2012 Edit **Changed the mount command - thanks viperboy!Added steps to possibly resolve issues with previously rooted systemsChanged a few steps to be a little bit easier.**Jan 24 2012 Edit **Some people are reporting issues with this method. I suspect this is due to previously having root or other altered files. A method that has worked for some is to update to 9.4.2.11.1 and then following the above procedures. Please note, this firmware release is unofficial and at this time THERE IS NO DOWNGRADE PATH.
