As Samsung had promised, the Galaxy Ace 2 GT-I8160 was entitled to received the Android 4.1.2 Jelly Bean update. The leak of the JB test firmware for the device a month ago confirmed it and the actual official 4.1.2 update began rolling out early this month. The new firmware is still being pushed via OTA thousands of Ace 2 owners have already upgraded their phone.
However, from the early reactions of the Ace 2 users it appears that they are not that happy with the update because JB has made their phone slower and laggy. Some users are also complaining the fast battery drain and to get back to the glorious Gingerbread days, most of them are now seeking a way to downgrade from Jelly Bean to Gingerbread.

What If I Get a Bootloop after Downgrade:
Well, we have tested this method and it worked without any mishap or hindrance but it is not necessary that things go nice for everyone. If you installed the downgrade firmware and got the PASS message on Odin and your phone does not boot normally afterwards, do the following steps:
- Pull out your phone’s battery, wait for a minute and reinsert it back to its place.
- Then boot your Ace 2 into recovery mode: press and hold Volume Up + Home + Power keys for about 5 seconds till the Samsung logo with device name blinks for 2 times followed by a black screen with an Android bot and blue menu. This is called stock recovery mode and here you will have to use the Volume keys to scroll and highlight options and the Power key to select them.
- Okay, scroll down to “wipe data/factory reset” option and confirm your selection.
- Next scroll to “wipe cache partition” and wipe it too.
- Finally select “reboot system now” option.
Your phone should boot now and if it is still stuck at bootloop, try installing the firmware again and more carefully. Remember, if you encounter an error, it’s certainly a mistake made on your part.
Please note that the downgrade firmware for the Galaxy Ace 2 is basically in Russian language.If you have any problem with the language of the device, download the firmware of your country from here and install it. Remember when you install the new GB firmware, you need not use any PIT file. So what you have to do is to click on the PDA button and select the file with .tar.md5 extension (in case the downloaded firmware has a single file). You can also use the procedure described here and download the new firmware from here.
