[Sony Xperia C] Amith Magajikondi:
Sony Xperia C Unbrick

Hi... I came across this problem recently while installing CWM using MobileUncle Tools without changing the Boot-version. If your Boot-version is not supported, then you need to first convert it to the suitable Boot-version. There is a seperate Xperia C XDA thread on install CWM on both the Boot-versions. Now in your case, you have flashed a wrong recovery which has bricked your device.

Here is a step-by-step guide on how to un-brick your Xperia C. This worked for me. Hope it works for you too...

1. Firstly, remove the back-cover of your Xperia C and remove any sim or memory card, if connected.

2. Now, search for a small hole with "RESET" written below it.

3. Use a pen to press it. Hold it there for a minute. Then leave it and put the back cover back.

4. Charge your device for about 10 minutes.

5. If you do not follow the above steps, you won't be able to repair your device through PC Companion.(The update stops showing "Download error or error 1200). This is because your device still has MobileUncle Tools and unsupported Recovery image installed in it which does not allow the stock Recovery to be installed. When you reset by following the above method, only the stock apps are left in the device, deleting every other app.

6. Now download and install the latest Sony PC Companion from the official site, to your PC.

7. Open the PCC and click start in support zone. Let PCC download and install the required files.

8. In the next menu, select the software update option. Instead of clicking on install, select "Repair" device which is highlighted in blue.

9. Follow the steps until PCC starts to prepare your PC for software update.

10. In the device selection menu, select Sony Xperia C C2305 and click next.

11. When the next menu appears, disconnect any USB or multimedia drives attached to the PC. Now, first connect your original Sony USB cabel to the PC. Then, turn off your device(If the device is not turning off i.e. switching on after connecting the USB cable, read the instructions given at the end). Wait for five second. Press and hold volume down button of your device and connect the USB cable to your device. A green led appears on your device if the device is connected properly.

Note: If a continous red led appears instead of green, do not worry. Keep the device connected to PC intact for about 5 to 10 minutes. It will turn green. This is because, bricked devices take some time to be recognised.

12. Now the update process starts. If all the above steps are performed correctly, then surely the Device Software Update process completes without any errors or stopping in between.

13. Then click finish in the last menu after Device Software Update Completes.

14.Disconnect Xperia C from PC and press the Power button.

15. Xperia C boots up. Do not worry if your screen isn't the way it should be(e.g. whitish at the edges and the Sony Wave logo lagging). As this is the first boot-up after software update it takes sometime to recover to it's earlier charm. After about a minute or two, your device will be perfectly all right.

Note: The first boot-up takes some time(about 5 to 7 minutes).

16. So, this is it. You will have your Sony Xperia C perfectly working if you follow the above steps cautiously.

Hint for step no. 11: Follow this only if your device turns on after connecting the USB cable:

1. First, let the USB cable be connected the PC.

2. Force switch off your device by pressing Power + volume up buttons for about 10 to 15 seconds when it is stuck at Sony logo.

3. When the device turns off, immediately leave the two buttons and press and hold volume down button and connect the USB cable to the device, before the device turns on.

4. Now your device would be properly connected and the green led appears.

Hope this helps you. If you have any other queries regarding the same, please do inform.
