Upgrade Galaxy ACE to Gingerbread 2.3.5/2.3.6 | How to Root & Unroot
Earlier we have written about many custom ROMs for Galaxy ACE. If you want to upgrade to them probably you will have to change to the latest baseband of Stock ROM according to their need. But there are many users who do not prefer to use Custom ROMs for them also updating to new version of Stock ROM is important.
Updating to the never version becomes mandatory as it not only improves the performance but also eliminates any known bugs in the existing version. The considered safe way to update your ROM is via Samsung Kies as it is official. But again it is often seen that it is too late when we get our update. So the other way around is to step ahead and do it manually. To be clear, flashing and updating your phone manually has no harm and no damages until you do some thing terribly wrong. For instance, pulling out the usb cable while flashing is going on. Well that is silly!
So, now lets move on with our tutorial to update ACE with Gingerbread 2.3.5/2.3.6.
Things Required before Flashing
The latest Stock ROM files
Download the latest stock ROM files from Samfirmware.com or from Tsar3000. In this case we will be using ROM XWKS9 as it is the latest 2.3.5 or download any Gingerbread 2.3.6 ROM from below link. If you have problem downloading from there do so from mediafire link below.
Download: Gingerbread 2.3.5 XWKS9
Update: Download Gingerbread 2.3.6 for Galaxy ACE.
Download: Ops file
The tool that we will be using is Odin, obviously the only tool available for flashing. If you do not have this download from here.
Once the files are downloaded you are all set for the action.
Note: Please check the downloaded ROM and Ops whether it is fully downloaded or not. Corrupt files will lead to bricking. In general we do not face problems but in some cases like in case of Firefox download manager files are some times said as completed fully when internet gets disconnected for a while. so best way is to check the downloaded file size. This is just a precaution and nothing much, as in this case you have to extract the files from rar. Extraction will fail if file is corrupted.
Updating Galaxy ACE to Gingerbread 2.3.5
First and the most important thing, if you are flashing your phone for first time you need to be calm and relaxed. Now, follow the given steps. I am assuming that you have your phone drivers installed on windows. just install Kies once and get you phone recognized by windows. But before proceeding with next steps exit Kies or alternatively install Samsung Official Drivers for Galaxy ACE.
- Open Odin and put the .ops file under option Select OPS.

- Select the One Package file.
- Your system is ready now its turn for the phone. Switch off phone, now press and keep holding middle+power+volume down keys together till your phone enters Downloading Mode. Keep phone’s back cover open, so that you can pull out battery if you miss the downloading mode and the phone starts rebooting ( saves a lot of time).
- Now connect your Phone to system Via USB. You will see Odin has recognized the port.
- Select the One Package option, select the OPS file and the single ROM file in ODIN.
- Click on start and sit back. It will start the installation and automatically reboot your phone.
