• use this tutorial only with the Samsung Galaxy Ace model number S5830. Don’t attempt to install this SGS2 JB custom ROM on the S5830i smartphone. 
• The Galaxy Ace you’re about to update should be rooted and running the CWM Recovery image. Without these you won’t be able to flash the Update files.
• Use the custom Recovery mode and create a full Nandroid backup of your current ROM. This will set a restore point for your phone and you can use it in case you don’t like how the new OS runs for your device.
• The tutorial will ask you to factory reset your device, which is why you will have to backup your SMS, Call logs and other similar data. Use some of these tools for all those backup actions: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. Note that some of these apps will ask for root access, which you have to grant it for them when asked.
• Sync your Gmail account with the Contacts data and you will not lose any important phone numbers and other data from your People app.
• Enable USB Debugging option from the Android Developer Options menu.
• Make sure that your phone’s battery charge level is over 50%, this will prevent the phone from powering off in the middle of the updating process. In case your device does power off, then you will be forced to repeat the entire tutorial starting with step 1.
• We can’t be blamed in case you brick your phone or you lose any files in the updating process. It is a guide for advanced users and you need to install the new ROM only when you’re sure that you can complete the guide with success.
• Read the entire post and use the comments section to ask for any help in case you cannot complete the install.
