randomly downloaded root files from several sites across web. Tested each of these files. While some terminated abruptly, some files gave errors like "Unable to get shell root". It was more than frustrating, not to be able to root my device. Earlier I had used applications like "Superoneclick" and "Unlock Root" etc. to root my earlier handset (Samsung Galaxy Pop SCH-I559) with ease. Even these had failed to root my new phone.
After all these trials and error, I finally succeeded in rooting my Samsung Ace Duos. If you think I used files related to Samsung Galaxy Ace, you are wrong. Samsung Galaxy Ace and Samsung Galaxy Ace Duos has different features all together. Even if the name sounds similar, nothing seemed common between the 2.
Here is a quick method on what I did to make it work.
Do backup all your content before you proceed and pls dont blame me if anything goes wrong as you are the one who wants to try it. Just a word of caution incase :)
The files I used are meant for GT-S6102 ( GALAXY Y DUOS), but worked well for Ace Duos
Remember in recovery touchscreen will not work use volume up down & home keys.
1. Uninstall all [Root] apps.
Caution : Both files are related to each other, If rooted with "update.zip" from here then only use "unroot.zip"
If you do try it, pls write back mentioning your feedback and comments. Thanks.
