[Q] Need a hand with root...

Hey dudes, thanks in advance for reading.

Having a tough time rooting this thing - B90; stock ICS 4.0.3; build 9.2.1.17

I've tried viperMOD (although the version 4.5 download link is broken so tried the old version) - no results

I've tried nachoroot (http://xdaforums.com/showthread.php?t=1427838) and end up with this error:

failed on '/data/sensors/AMI304_config.ini' - Permission denied
link failed File exists
/data/local/nachoroot.bin: break: cannot break

I've tried rolling the firmware back via )http://xdaforums.com/showthread.php?t=1417006) but when I try and enter recovery, I get the gears for a couple seconds then the dead android.

I have the Asus Sync software installed (not running while doing any of this, nor the stupid Splashtop streamer which won't uninstall) for the drivers.

Has anybody had any luck rooting the later models? I can't be SOL, I want to like this thing but the stock android is crippling the user experience. Any help or relevant links would be greatly appreciated!

Just ran viperMod again, option 1 (I only have 3 choices, root, unroot, exit). This should be viperMod 4.1.

The script finished and rebooted twice just like the nachoroot procedure. After the second reboot I get uid=2000<shell> gid=2000<shell>, ....

These two entries should be zero, no?

Does anybody have a copy of the viperMod 4.5?

genius! it works.

thank you sir for finding the file and thanks to viperboy for the script. on to flashing.
