Active 43 do not need unlock.

A particular exe on a device works perfectly, on another it causes a restart. This is a very common case, even with some noname china devices.
When iGO during close report error - it is simple > put (SD) card in device and that is it. It can sometimes be a solution in this case as well.
But, usually, reboot is much more complicated, and that is just conflict between launcher and exe.
There is no general solution.
- on some devices it was enough to change data.zip
- on some other add some ux (skin) files fixed problem (surprisingly)
- on most of them changing exe was only solution. Sometimes i tried over 20 versions.

As I already pointed - on Becker devices Becker software is the best choice, Becker 9.6.8.286435 (Ready, 6 Mar 2013) is one of best versions. Or Revo 1/2.
