http://forum.motofan.ru/index.php?showtopic=157374We will need the following things:
1) R6713_G_71.14.1CR_A reflash
http://motofan.ru/firmware/?action=view&am...nt=1&phone=2) R6713_G_71.02.07R reflash
3) SBF-Recalc 1.2.8 software
1) Parse R6713_G_71.02.07R using SBF-Recalc to get CG31. We won’t need other code groups so you can delete them.
2) Parse R6713_G_71.14.1CR_A
3) Create new folder and copy to it all CGs (except CG31) from R6713_G_71.14.1CR_A and CG31 from R6713_G_71.02.07R
4) You can also unpack ?G43 and CG52 using Cyngwin to change skins, pictures, ringtones or java games. It is also possible to edit flexbit and to add autorun.
5) Build everything you made with SBF Recalc (v1.2.
. You will need to select the following options on ‘Advanced’ tab: ‘Calculate All New CG's’, ‘Write New Descriptor’.
6) Reflash your phone.
As a result we’ll get CG52 unsigned and possibility to downgrade to older SWs. This won’t work for you if you have already flashed R6713_G_71.14.1CR_A (with signed CG52).
