So guys i searched yesterday to find a way to unbrick my phone and i haven't. But i thought how could this thing now can be unbricked.... So i found a way that worked for me .
1.If your phone can go to downloading mode (Odin mode) then put it there.
2.If you have (jelly bean 4.1.2 OS) and you have the right files when you used them to get jelly bean 4.1.2 through Odin ... continue.
3.Do the same procedure that you've done while your phone was good and not bricked to transfer your gingerbeard (2.3.6) to jelly bean (4.1.2)
4.It should work all good.
P.S It worked for me and i tried it cause i had nothing to lose with my bricked phone but now i have everything to lose so it's better to be safe than to be sorry.If you want to upgrade your phone from jelly bean or gingerbeard or any other OS you are using , better take it to professionals who work on these things and have the warranty on your pocket.
That's it guys i hope i helped some of you and remember , use this while have the Samsung Galaxy ACE II (model GT-I8160).
P.S2 I know nothing more about this so everything i know is inside this post.
Thank you in advance! Bye bye.
