Engineer Mode MTK Shortcut

Jul 22, 2015

v1.5 Fixed a bug due to which on some devices could not get out of the Engineering Menu button "Back".

v1.4 A new attempt to circumvent the protection on some devices (basically, it's some models Huawei), which does not allow to run third-party programs Engineering Menu.
In these devices, the program must provide a Root-access (otherwise - in any way).
On devices without Root also remain possible alternative to running through a set program number *#*#3646633#*#*.
