[Upgrading, Modifying and Unlocking] NSDCars5:
<h1>Make your Spreadtrum phone faster, less buggy, and more usable!</h1>

This guide is supposed to tell you how to make your Spreadtrum phone better to use. I'm not good at introductions, so let's start.

1. Root your phone, and install ClockWorkMod. Make a full backup. If something goes wrong during the guide, you'll need to restore from this. An excellent guide for this is given here: http://xdaforums.com/showthread.php?t=2165554

2. Install Chainfire3D from the Play Store. Install the CF3D driver by opening the app and going to CF3D Driver --> Install. Get the NVIDIA plugin from here: http://nsood.in/nvidia.zip Put the plugin in sdcard/plugins/ Open CF3D on your phone, and scroll down. Select Install Plugins/Shaders and select the NVIDIA plugin (nvidia.zip). Then open "Default OpenGL settings" and scroll down. Select "Use plugin" and choose the NVIDIA plugin. This will speed up not only your games, but also the UI in general.If any error occurs, go to ERROR: How to Revert Back To Stock.

3. Get a root browser/explorer. I recommend the one by "JRummy". Also, get the following apps from Google Play, and make sure they are NOT installed to an SD card:

- A messaging app (for SMSs) (I'm using Messages+)

- A dialer app (I use Dialer+)

- A contacts app (I use Contacts+)

- A launcher (I use LauncherPro)

- A browser (I use Lightning)

Note that you can get any app, but these seem to work pretty nicely with my Micromax A27 with a Spreadtrum SC6820 chipset.

4. Set your downloaded apps as defaults. Open your root explorer, and navigate to /data/app. Long press your messaging (or any other of the above) app, and move it to /system/app. Repeat for all apps above. Now navigate to /system/app and delete all default apps, launcher first. Note that your phone may reboot after the deletion of an APK. Just open your root explorer and continue.

WARNING: Do NOT delete any other APK. Just the default SMS app, dialer, contacts, launcher, and browser. If any error occurs, go to ERROR: How to Revert Back To Stock.

5. Disable all special effects in all apps. This is a simple step, so I expect you to do this on your own, or Google it.

6. Use low-memory apps and games, for example, instead of Subway Surfers or Temple Run, play something like Line Runner or Hill Climb Racing. This helps reducing overall memory usage, allowing your system to have more breathing room.

That's it. Feels strange, being a noob somewhere and not being noob-friendly... Oh, and:

ERROR: How to revert back to stock

This guide has many steps going near the guts of Android. If, during any of these steps, your phone's gut goes off, and you're stuck in a bootloop, or can't get past the lock screen, do this:

Power off your phone and disconnect it from your PC. Open a Terminal/Command Prompt window in your ADB folder. Put this command in:

adb shell reboot recovery

Do NOT press Enter! Not yet! Connect your phone to the PC and power it on. As soon as you get the device logo, press Enter. You should go to ClockWorkMod. Go to Backup and Restore --> Restore --> DD/MM/YYYY --> Yes. Your phone will reboot automatically, back to a stock+root mode. Well, at least your phone works now!

If I helped you, press Thanks. Else, hate me silently for the rest of your natural life.
