I did successfully root a TF700t with 9_4_5_22.
Now I tried the same method after upgrading another TF700t from stock to 9_4_5_26.
Everything works fine during rooting (I've tried both manual and automated DebugfsRoot 1.9) with the following exceptions:
1. during the 3rd stage of rooting, I get
/system/bin/sh: /system/xbin/su: not executable: magic 7F45
Superuser access does not seem to be active after rooting. I did uninstall and re-install Superuser with no superuser access success.
I tried both under XP and 7/32 on the same device, no errors but root does not seem to be active. Between rooting attempts, I restored stock ROM.
Asus USB drivers installed (off Asus website)
Asus synch is disabled and prevented from launching.
Security/Unknown sources is checked.
Developer options / USB debugging is ON/checked.
What do you think goes wrong?
Any help is appreciated. Thx
