Up next you need to read and complete the next pre requisites. I have mentioned the same during the following list, so don’t skip this section.

Install a custom recovery image (such as CWM recovery) on your phone. This tool can be installed only on a rooted OS; also you will not be able to update your Xperia neo V to Android 4.2.1 without using CWM recovery.

Then, a Windows running computer will be required. Uninstall all the security tools and settings that are being running on your computer and smartphone as these tools are usually interfering with the update operation.

Check the battery status on your handset and if there is less than 60% power left charge the battery before heading to the proper steps.

Enable the USB debugging option by going to “Settings -> Applications -> Development -> USB debugging”.

And do not install the CM10.1 Android 4.2.1 Jelly Bean firmware on any other device similar with the Sony Xperia Arc S as this guide can be applied only for the mentioned phone.

Disclaimer: The procedure given in this tutorial is considered as risky and may cause damage to your phone. It is recommended that you should not follow it unless you are familiar with these things. Follow this guide completely at your own risk. We or Cyanogenmod team won’t be held responsible for any damage caused to your device while attempting these steps.

Procedure to Update Sony Xperia neo V with Cyanogenmod 10 Custom ROM:

  • Since Google Apps are not there in the ROM by default, you have to flash them manually. Download GApps from the link given below.
  1. GApps for Jelly Bean
  • Connect your device to the Computer using a USB cable. Enable mass storage mode & copy/transfer ROM package & Google Apps file to the external memory slot on your device.
  • Now switch off the phone & boot into the Clockworkmod Recovery. For doing the same, tap Volume rockers few times while the phone restarts.
  • After getting into the recovery, make a nandroid backup of your current ROM so that it can be restored in case of failure. To do so, Highlight ‘backup and restore’ option in the recovery menu, select it & then choose ‘backup’ to start the backup process.
  • Select ‘wipe data/factory reset’ & subsequently ‘wipe cache partition’ to wipe the data & caches respectively from the phone memory.
  • Now select “install zip from sdcard” & then on next screen select, “choose zip from sdcard”. It will show you the files & folders located on the root directory of your device. Navigate to the ROM file, select it using power button (unless you’re using touch CWM) & confirm the installation by pressing on ‘Yes’. This should start installing the ROM.
  • As soon as ROM installation finishes, again select “install zip from sdcard” followed by “choose zip from sdcard”. This time search for the ‘gapps-jb-20121201-JOP40D-zackconsole cm10.1 only.zip’ & install it.
  • Select +++++Go Back+++++ to land into the main menu of recovery. There, select “power off“.
  • Up next, you need to flash kernel image required to boot CM10.1. For that, follow the steps mentioned in further article.
  • Download the fastboot files
  1. Fastboot Files
  • Extract the zip file, you will find four files inside the fastboot folder.
  • Open Cyanogenmod 10.1 ROM package using software like WinRAR or 7-zip, extract boot.img file (located at the root directory of ROM) to any convenient location.
  • Now move that kernel file in the fastboot folder so that now it will contain total 5 files inside.
  • On the phone (while switched off), enter into the fastboot mode. To do so,
  1. Press & hold Menu Button while connecting your phone to the PC.
  2. Open the Fastboot‘ folder where the fastboot files are located.
  3. Now Open command prompt & Point its directory to the fastboot folder (OR You can do the same as: open Fastboot folder, Press & hold shift key and then right click on the free space in the same folder.When right clicked (holding shift), you’ll see ‘Open Command window here‘ option. Click it & Command prompt will be open pointing to the Fastboot directory).
  • Type the following command in command prompt to flash the kernel file:

fastboot flash boot boot.img

  • Restart the phone by typing “fastboot reboot” (without quotes) in command prompt.
  • Your phone may take some time to boot than the usual. This is normal & happens only for the first time after installing a new ROM. So be patient.

Tip: You can restore back your previous ROM using CMW’s restore feature. To restore the previous ROM, boot into the recovery mode, select Backup and Restore option & on next screen, select restore. Now choose the backup you like to restore (or the restore the backup you’ve made before flashing this ROM).

  1. I installed the ROM and it’s beautiful, but in my Neo (with the 420mb user space modification) it’s very laggy, touch screen don’t response as normally but generally I think this is a good starting point to develop the android 4.2.1 for our devices, actually I have installed CM10 and it works very fine (except HDMI and front cam for gtalk, for skype works), for me it’s a daily device and runs all my apps and all the communications apps that I need to work. Good job and it demonstrate to Sony that our devices are not dead in 4.0.4. Thank you

  2. •Now switch off the phone & boot into the Clockworkmod Recovery. For doing the same, tap Volume rockers few times while the phone restarts.

    • Leave some empty space in the internal memory. When there is less than 10 MB left in the internal memory, Android can become very sluggish. Leave at least 20 MB. In my experience, low internal memory is often the root cause of sluggishness (and random errors).

      Use app2sd as much as possible, especially if you have small internal memory

      Uninstall big applications that you do not use much.

      (!) In rooted ROM, you can use pm setInstallLocation 2 trick to force installing applications on SD card (note that not all applications can be safely installed on SD card).

      (!) When system applications are updated, the original version of the applications are not deleted so you can uninstall the update. This takes up valuable space; if you’re rooted, you can remove the stock application entirely and reclaim this space. I do not recommended this unless you are already using a Modded ROM since you can no longer use “Factory Reset” to return your system applications to the factory version (at least not without reflashing a fresh stock ROM).

      Choose fast applications.

      Use Opera Mobile or Mini. The stock browser is a great browser, however it’s also quite sluggish (even Google’s mobile home page it is sluggish as hell). Opera’s touch interface is a bit annoying to use, but it is much snappier than the stock browser.

      Choose a fast Home Screen. Some manufacturers equips their phones with pretty, but sluggish home screen. You may want to use a simpler and faster home screen apps. Also, live wallpapers kills snappiness; if you want to use them, use the simpler ones.

      Do NOT use Task Killers, especially the automated ones. You should not Force Kill an applications unless you are sure that the application has gone extremely wrong and the application is ignoring a more polite requests to shut down. Force Killing applications may leave dangling resources in system services that cannot be safely cleaned up. Leave the job of killing applications to Application Life Cycle.

      You should not need to clean caches, caches are there to speed up applications. If an application’s caching causes it to slow down, report that to the developer as a bug.

      Cleaning out cache may temporarily help with #1 (low internal memory), however cleaning cache is only a temporary fix. The application will just generate the cache again, and your memory will fill up again. Some applications allow you to adjust the size of the cache, which is much more useful permanent solution than cleaning out cache. Generally you want to give applications as much cache as possible while still having a decent amount of space in the internal memory.

      Applications that have big caches (e.g. maps) should cache to the SD card, file a bug report to the application developer if they don’t.

      Due to the nature of caching, there are times when cache may become inconsistent and this may confuse the application, possibly causing random crashes, slowness, ANRs, or other random behaviors. This sort of thing is rare, but it does happen. Generally, you should leave the cache alone unless you suspect there are erroneous behaviors that may be caused by bad caches.

      Upgrading Android may bring performance updates, however higher Android versions tend to be bigger than the previous ones and may cause #1 (low internal memory). If an upgrade leaves you with much smaller internal memory that you cannot install all of your favorite applications and have some space left, you may want to stay at an older version.

      Android 2.2 (Froyo) comes with a JIT compiler (Just In Time Compiler) that will increase CPU-bound programs by up to 5x (in my Spica, JIT raises Linpack’s score from ~3 to ~9). Sluggish program is usually I/O bound, but helping with CPU-bound processes helps quite a bit.

      Android 2.3 (Gingerbread) have an improved task management, the Application Life cycle will kill applications that causes sluggishness and battery usage. Gingerbread also have concurrent garbage collector, which should reduce random stutters/pauses.

      Some applications can slow down when they have a large amount of data or a large number of items to manage. For example, the stock SMS app on the Incredible gets progressively slower as it accumulates more messages. The only way to fix that is either replace the app, delete messages, or archive them off the phone (SMS Backup+ is great for this).
