Cyanogen Mod 9 For Galaxy Ace GT-S5830 Smartphone.

Cyanogen Mod 9 is the latest version of cyanogen mod custom rom from Cyanogen Mod Team based on latest Android 4.0.3 Operating System. Cyanogen mod team started working on this latest version as soon as Google released the source code for (latest Ice Cream Sandwich based) Galaxy Nexus smartphone around the end of the November, last year. And, since then it has been a challenge for other developers to port this latest CM9 rom to their android device. One such group of the developers known by TeamHackAce, started this innovation for their Samsung Galaxy Ace GT-S5830 smartphone. And, it seems like their effort paid out as we can seem quite stable versions of Cyanogen Mod 9 roms for Cooper (galaxy ace) out there.

Though the project is still not completed and the devs are not able to get everything working on their CM9 port, important features (or parts) of the device are working fine with the latest Legacy build of CM9 rom. Below is a list of things that are working pretty fine after many revisions of alpha and/or beta builds.

Kudos, to developer for their amazing work to make all these important features work fine on galaxy ace gt-s5830 smartphone. So, before you give CM9 a try let me inform you that this custom rom is currently a Work In Progress, so it might have different issues regarding stability. So, it is suggested to do a complete backup of your rom before flashing this. Also,  if you are worried about losing/bricking your phone then it is suggested that you stay away from all this until a more stable version of CM9 is released. Also, have a look at some of these screenshots of CM9 before flashing this rom.

This rom boots fine and all sensors, 2g/3g, wifi, gps, stock browser, audio, video, etc work pretty fine without no/few errors. Google Apps and File Manager are included while Chinese keyboard and dictionary are removed. Overall this rom should not disappoint you except for the camera.
