ROOT

Root provedete nahráním SIYAH KERNELU přes odin.

KERNEL : http://www.gokhanmoral.com/

Odin: http://forum.xda-developers.com/attachment.php?attachmentid=1168421&d=1341114315

DUAL BOOT

Jelikož už máte siyah kernel, vaše romka teď obsahuje program Stweaks, takže jí otevřete a povolte root práva.

Zajeďte na dual boot, a dejte reboot do 2nd rom utils.

Spustí se recovery, kde najedete na dual boot options a dáte clone 1st rom to 2nd rom.

pak dáte wipe 2nd rom

po flashnutí romky dejte fix permissions

Do druhé romky dávejte pouze AOSP nebo AOKP systém, kvůli kernelu.

Ujistěte se, že máte baterku alespon na 90% a 2gb na interní paměti.

a to je prozatím vše.

1- Reset přes Triangle Away
2- Vypněte telefon a jděte do download modu.
3- Flashněte přes Odin stock firmware, který chcete.
Po této mětodě je flash počítadlo 0. Pokud si dáte jinou romku, nebo jiný kernel, vykřičník se vrátí a počítadlo flashů se opět zvýší na 1.
