[Galaxy Ace II General] Codename13:
THIS THREAD HAS NOT BEEN UPDATED FOR AWHILE. IF YOU HAVE ANY QUESTIONS ABOUT ANYTHING IN THIS THREAD, SUCH AS AVAILABLE CUSTOM ROMS OR KERNELS, PLEASE MESSAGE ME

The Samsung Galaxy Ace II X (GT-S7560M) is a Canadian variant of the Samsung Galaxy Ace II. The two devices have nothing alike except for the build. The Ace II X has a Snapdragon MSM7227A chipset (1 GHz Cortex-A5 CPU and an 'enhanced' Adreno 200 GPU), 768MB RAM (645MB accessible), 4GB of internal storage (1.8GB accessible), a 4" display, a 5 megapixel rear camera, a 0.3 megapixel front camera, and (the biggest difference is that it) runs on ICS 4.0.4 with Touchwiz Nature UX. The Ace II X is essentially the Galaxy S Duos (GT-S7562) but without dual SIM card support.

The purpose of this thread is to keep all the development for this scarce variant organized. Below is a list of things accomplished with the Ace II X:

1. Rooting

The purpose of rooting is to allow access to higher level permissions so that you can do more with your phone such as remove any junk apps (called bloatware) that are installed on the device by default, increase CPU clock speed (so the device runs smoother), change how the phone manages RAM, and more. As of now, there is no stock firmware dump, so once you root, your warranty may be voided. The root procedure involves flashing CWM recovery, then rooting via CWM.

To root your Ace II X (on Windows)

-Download the "root kit" here.

-Extract the files from the download once it is complete.

-In the folder Odin307, there will be a file called "Odin3 v3.07.exe". Double click on it, and it should open a program called Odin.

-Click the button 'PDA' (on the left of the window) and select the file 'recovery.tar' (that should be in location where you extracted the root kit).

-Make sure that only 'Auto Reboot' and 'F. Reset Time' are checkboxed in Odin.

-Power off your Ace II X and hold down the power button, the home button, and the volume down button all at once.

-Press the volume up button and connect your phone to your computer with the USB cable that was included in the packaging for your Ace II X.

-A box in the top left of Odin called 'ID:COM' should turn yellow.

-Press start and your device will reboot when it is done.

-Power off your device and hold down the power button, the home button, the volume up, and the volume down button all at once.

-Let go off the buttons immediately when the 'Samsung Galaxy Ace II X GT-S7560M' logo appears.

-Transfer the file "CWM-Superuser_1.0.1.7.zip" to a micro sd card, and put the micro sd card in your device.

-Select 'Install zip from sdcard' (in CWM recovery) using the volume keys to scroll up or down and the home button to select an option.

-Select the "CWM-Superuser_1.0.1.7.zip" that you put on your micro sd card earlier.

-Wait a moment or two and your device will be rooted! Enjoy!

NEW METHOD OF ROOTING FOUND. This new method involves using a program (Windows only) called UnlockRoot. Follow the instructions found there to root without increasing the flash counter (yellow triangle) or getting rid of stock recovery. Stock recovery can be found here for those that have rooted using the root kit.

2. Remove the Yellow Triangle At Boot

Once you root, a yellow triangle will appear on the bottom of your screen whenever you turn on your phone. This happens as a result of rooting, and it shows that your device has been modified. Removing the triangle requires a simple application.

-Download the application Triangle Away from the bottom of the first post of this thread.

-Transfer the file to your micro sd card.

-Go to the Settings app, Security, and select 'Unknown Sources' to allow the installation of non-market apps. Click OK on the box that pops up.

-Using the My Files app (comes with the device), navigate to the external sd card and select the .apk file that you transfered to your sd card earlier.

-Click 'Install'

-It should install. Open it.

-Grant the app 'Superuser permissions'.

-Select 'Reset flash counter'

-It should make the yellow triangle disappear. Enjoy!

3. Deodexing

Stock ROMs are odexed, meaning that each system application (.apk) is split into two parts: The .apk and the .odex. An odexed ROM takes up less space and is a bit faster because its .dex files are optimized, thus making .odex files. A deodexed ROM means that the two parts are assembled into a single file (.apk). A deodexed ROM takes up more space (a bigger dalvik cache) but allows for more modifications. The /system/framework folder must always be completely deodexed or odexed, but the /system/app folder can be partially deodexed (if the framework folder is odexed). Anyways, I have deodexed the stock ROM and made it into a CWM flashable package.

- Download the two .zip files from here and here.

- Place the two .zips on your external sdcard.

- Power off your phone and boot to recovery mode.

- First install the OdexRemover.zip.

- Once it finishes, immediately flash the StockDeodexed.zip.

- Reboot, and you're done!

4. Kernels

Kernels are essential. Packed in a boot.img file, a kernel is the link between the hardware and the software. It basically controls your device's CPU speed and RAM management. The problem with the stock kernels are that can cause lag, or slowdowns. With a custom kernel, you can freely raise or lower the fixed clock speed to get better performance or save battery power. You can also change how the device manages Random Access Memory for a better and smoother experience. Currently, there are only a couple kernels available:

- Stock Kernel (Insecure) by Codename13

- KyleOpen Kernel (Original by cheatman) ported by SeannyM

-

Instructions for installing one of the following kernels is as follows:

- Download the file.

- Using Odin, simply refer to the instructions for rooting the device, only use the kernel.tar.md5 file in the PDA section (instead of the rooting kit)

- Boot your phone to download mode, plug it in to your computer and click start!

- Wait a moment until the operation is completed.

I AM NOT RESPONSIBLE FOR ANY DAMAGE CAUSED BY NOT FOLLOWING THE INSTRUCTIONS PROPERLY. PROCEED WITH CAUTION WHEN FLASHING A KERNEL AS IT IS A VERY SENSITIVE PART OF THE DEVICE. YOU CAN BRICK (BREAK) YOUR DEVICE IF A KERNEL IS MISFLASHED.

5. Modifications

Probably the best part about rooting is that you can modify your device however you want. I have merged several mods that I have done on the device into a single package. Install the file found in the link here

using Clockworkmod Recovery mode. The current mod compilation, Mod Pack II X v0.4, adds several mods. The list can be found in the linked page. The link will be updated when a new mod pack is released (no ETAs please).
