[Sony Xperia C] notauseranymore:
ANYTHING THAT HAPPENS FROM HERE ON WE WILL ATTEMPT TO SEE WHAT CAN BE FIXED BUT DO TAKE NOTE THAT BRINGING IT TO A SERVICE CENTER AFTER MODIFYING ANYTHING AND THEY WILL TELL YOU THE PHONE NEEDS A NEW MOTHERBOARD FOR THE PRICE OF A NEW C3. YOU HAVE BEEN WARNED, SO TAKE EXTRA CAUTION

Hi everyone, this is a general thread for those wishing to break into your new C3 device now that a window has opened in terms of firmware.

Be advised, Sony has stated there will be no rear camera fix and no Marshmallow for the C3​

This guide will assume your bootloader is unlocked, if you do not have any idea what it means or how to get about it, you must divert your attention HERE for a bit. Use that link for know-how to unlock your bootloader, and only proceed after successful unlocking. For bootloader codes, select the Z3 Compact as your device, because it shares the same unlock key generation algorithm.

Now, first thing's first, let’s get root + custom recovery. This is important, because people have been recommending KingRoot and as far as I'm concerned that is the most asinine way to provide system privileges. You wouldn't believe the pain I endured just to remove it and install SuperSU, which is far more reliable. Anyone who wishes to disagree or feels offended by this preference may kindly sod off, no offence.

STOP!

This section is only for Lollipop 5.1 firmwares, anything else and we can't guarantee safety.​

Now that you read the warning, let's continue with recovery.

Head HERE for the D2533 files, and HERE for the D2502/D2503 files.

D2533:

1. If you want root as well, get SuperSU and copy it to your SD (Internal/External)

2. Unzip the .zip archive, this contains everything you need.

3. Turn off your phone and plug it into your PC/Laptop while holding the VOLUME DOWN button. It will install a driver first.

4. Double-click the .bat file in the folder of the extracted archive.

5. Read and accept the T’s&C’s

6. The recovery will now install XZDR. When your phone reboots, hold VOLUME DOWN. The green LED should turn PURPLE.

7. You will now be in TWRP recovery. At this point, you can install SuperSU, Custom ROMs, or anything you may otherwise want.

8. Once done, reboot your phone.

D2502/D2503:

1. You need these files first. If you want root, get SuperSU as well.

2. Add the .img file into your fastboot folder.

3. Now, turn off your phone and plug it into your PC/Laptop while holding the VOLUME DOWN button. It will install a driver first.

4. Right-click the space inside the folder while holding SHIFT then click 'Open Command Window Here'

5. You will see a command prompt window so just type

fastboot flash boot boot.img

6. It will send the .img files and let you know when done

7. Now type

fastboot reboot

to reboot your phone

8. When your phone turns on, a green LED will light up. Hold VOLUME DOWN, the LED should turn PURPLE.

9. You will now be in TWRP recovery. At this point, you can install SuperSU, Custom ROMs, or anything you may otherwise want.

10. Once done, reboot your phone.

Soooo, what now?

If you are a dev or would like to become a dev for this device, head HERE to restart CM12.1 development.

Come to THIS THREAD for information on deodexing your device and give it a fresh look. This is a relatively new development so be patient and check in once in a while for forum news.

Check out the custom stock kernel for the 5.1.1 stock ROM here.

In addition, with a recovery you can now instant reinstall your system for your D2533 or D2502 via zip flashing without adding root and recovery all over again.

Did you know that our phone is missing the Bravia Engine? Yes, a Sony without Sony's best feature. Fortunately it can be fixed, with your recovery just download and flash the files provided in this thread.

This thread is a work in progress, any questions are welcome. It is encouraged and we'll try our best to help so anyone can learn on what to do and what to improve.
