I decided to create this tutorial for C6943 owners. The kernel for C690X version is conflicting the Digital TV.
For the curious, I tell how simple it was to create the specific kernel: I downloaded the Firmware from XperiFirm and created a Bundle in Androxyde Flashtools (Tools / Bundle / Create-selecting just the kernel from the downloaded firmware)
Follows:
FOR THOSE IN VERSION BELOW 14.4.A.157:
1. You need to upgrade to version 157 via OTA or with help from the app 'Sony PC Companion'
2. Then follow the steps below to recover your root and keep your Digital TV working.
FOR THOSE WHO ARE ALREADY IN VERSION 14.4.A.157
3. Download the latest version of Androxyde Flashtools, install the drivers that came with it (make sure it is OK on the program: DEVICES / CHECK DRIVERS before continue.
4. Download the Kernel 108 for C690X and also the Kernel 157 C6943 (place both in the Flashtools\firmwares folder without unpacking)
5. Download the root script (click on SMALLER BLACK DOWNLOAD BUTTON) and a recovery for the 'locked bootloader'
6. Check if the phone is on version 157 and turn off the phone.
7. Open Flashtools, click the 'lightning bolt' icon and select the firmware 108. Click FLASH and plug the phone on computer holding the volume down.
8. In just a few seconds the app warns you that the procedure is finished and it will tell you to restart, do it.
9. On About, see that you still are on the 157 version, but with an old kernel June / 2014. Check out on options if 'USB Debugg' and 'Unknown Applications' are enabled. Apply Root (steps).
10. Turn off the phone after root is properly installed and repeat step 7 with 157 specific firmware for C6943. When done, restart and see if the kernel is 3.4.0 (09 / Oct / 14).
11. Everything OK, enjoy your Digital TV.
12. If you want, install dualboot recovery on Flashtools (steps).
