The Samsung Galaxy Ace is a smartphone that has been launched from some time and until now you would be able to run on it only CM7 / Gingerbread or some custom CM9 based on Ice Cream Sandwich 4.0. Now, an XDA Senor Member, Mac?aw managed to create a working CyanogenMod 10 test build that will bring Jelly Bean 4.1 for your Galaxy Ace phone.
Use the instructions in this article and you will learn how to successfully flash this new custom ROM. However, note that you should only install this CM10 preview Jelly Bean ROM only if you wish to test it, as there are some bugs and some features that aren’t currently working. The Galaxy Ace phone packs an ARM6v7 CPU and now it has become the first device that supports a Jelly Bean 4.1- based port. It would be better if you would create a full Nandroid backup of your existing ROM so that in case the new OS doesn’t impress you, you will then be able to restore your previous OS installation.
It has been confirmed that the GSM, SMS, EDGE, 3G, Signal are full working, as well as Audio, Sensors, Project Butter interface, Full 2D/3D acceleration, touchscreen, Sd card, Wi-Fi, Browse, live wallpapers. However the Microphone, Headphones, the small speaker, camera, FM radio, deep sleep and multiple other functions aren’t supported at the moment, but all these should be fixed in future versions.
