Update Xperia U ST25i to Android 4.1.2 Jelly Bean via Cyanogenmod 10
Pre - Requirements
Charge your Xperia U to at least 50% so there is no power interruption during this process
- Make sure it is running Official ICS 4.0.4 and not any other firmware such as Gingerbread 2.3.7
- Download Flashtool
- Disable all security related software (like Antivirus / Firewall) installed in your PC.
- Before you proceed further, make sure that you have unlocked the bootloader of your device. If you’ve not done it already.
- Custom Recovery like Clockworkmod must be installed in order flash Cyanogenmod Custom ROM. If you’ve not installed it yet, follow this .
- Please note that, above two steps shouldn’t be ignored as they are very essential to install Cyanogenmod 10 on Xperia U. Without them you can’t proceed further.
Step 2
Download latest Cyanogenmod 10 package from the link mentioned below.
Step 2
- Since Cyanogenmod doesn’t include Google apps, you also need to download & flash them separately. This package contains apps like Gmail, Hangout, Play store, Google+, Google Settings, Google Now, Play books / Movies etc. You can download GApps package from the link given ahead:
- GApps for Android 4.1.2 (Cyanogenmod 10) (Filename: gapps-jb-20121011-signed.zip)
- After downloading CM10 & GApps package, connect your device to PC. Enable mass storage mode on it. Now transfer these two files to your device’s internal storage. Don’t extract them else it won’t work.
- Switch off the phone and enter into the fastboot mode. To do so, Connect your phone to the computer. While connecting, press & hold Volume up button to trigger fastboot mode.
- Now, we need to flash a CM10 kernel which is required to boot CM10 ROM. Therefore, on PC, download Fastboot files:
- Extract ADB_files.zip to any convenient location on a computer. You will find five files inside your extracted folder.
- adb.exe
- AdbWinApi.dll
- AdbWinUsbApi.dll
- fastboot.exe
- runme.lnk
- Open Cyanogenmod 10 package using WinRAR or 7-zip, extract boot.img file (which is nothing but a kernel) on the desktop. You can find boot.img in the root directory of ROM.
- Move that kernel file (boot.img) in Fastboot folder.
- Now open runme.lnk file (from Fastboot folder) and type this command. This would flash the kernel on your device.
fastboot flash boot boot.img
- After flashing the kernel, disconnect phone from computer. Now, put your phone in recovery mode. To do so, switch off the phone, switch it on again, when phone is restarting (during boot logo & LED turns blue), repeatedly press Volume up button. Your phone will land in recovery mode. Note that, your phone won’t boot in recovery mode unless you’ve installed a custom recovery like CWM.
- As soon as you boot into recovery, make a nandroid backup of your current ROM so that it can be restored back in case if anything goes wrong. To backup your current ROM, selectBackup and Restore option from the main menu & on next screen, select backup. Now It will make a nandroid backup of your whole system. Wait for the backup process to get finished.
- Select wipe data/factory reset & subsequently wipe cache partition to wipe the data & caches respectively from the phone memory. Wiping cache partition is not necessary though, since Wiping data / factory resetting phone itself wipes many partitions but still it’s recommended. (Caution! performing this step will erase all the data from phone, therefore ensure that you’ve taken backup of all these things before. Please refer Pre-requisites section for the same).
- Now select install zip from sdcard & then on next screen select choose zip from sdcard. It will show all the files & folders located on internal storage of your device. Navigate to the CM10 ROM file that you’ve copied earlier , select it using power button (unless you’re using touch recovery) & confirm the installation by pressing on ‘Yes – Install ____’. This would start the installation process.
- Wait for the ROM to get installed. After ROM gets installed successfully, your phone will land in the recovery mode again.
- Again select wipe data/factory reset & wipe cache partition to wipe all the data & caches from the phone memory respectively.
- Now select install zip from sdcard followed by choose zip from sdcard & this time browse for Google apps package file (gapps-jb-20121011-signed.zip). Press on ‘Yes – Install gapps-jb-20121011-signed.zip’ to confirm Google Apps installation.
- After you finish flashing both files, select “reboot system now” to restart the phone.
