Well I try to use this to temporary root the Regza IS04 this the only way I know to temporary root.
z4root, gingerbreak superoneclick and many other rooting application to pc or android is no good because according to Japaneses blog The regza is04 kernel have a system lock
I'm talking about the android version 2.2.2 basedband ver 5014.1907.43
because the android version 2.2.1 can easily be root by z4root because there's no system lock
This is the guide for rooting Toshiba Regza IS04 from Japanese blog
One. root folder
We do the following to solve the problem of big inconvenience especially on the acquisition process and the root, is used.
In the normal-release kernel / system lock
· "Rogue applications ~" solutions for the errors
· Place / symlink to a path such as system / bin / su
By enabling the su using ISTweak, after this process, you can use the authority root.
ISTweak is for temporary root but before to able to use it you need to copy au from SHBREAK
But error keep pop up Error installing binary file:java.io.IOexception
Please Someone help me to what to do..
