C6603: How to update to 10.1.1.A.1.307:
For C6603: Download C6603.flashable.307.zip (736MB) and Xperia_Z_C6603_10.1.1.A.1.307_BE-stripped.ftf (14MB), save it somewhere you remember;
Put 'C6603.flashable.307.zip' on (the external) SDcard1;
Put 'Xperia_Z_C6603_10.1.1.A.1.307_BE-stripped.ftf' inside the Flashtool/firmwares folder;
Create a backup of your phone in CWM or TWRP and don't forget to backup the contents of 'SDCard0';
Flash everything in 'Xperia_Z_C6603_10.1.1.A.1.307_BE-stripped.ftf' to your phone and boot the phone straight to recovery after that;
NOTE: If you have an unlocked bootloader, you CAN flash the kernel, but you do not need to, to keep your custom kernel. DooMKernel v7 has support for this ROM version.
Flash 'C6603.flashable.307.zip' in recovery (Works in both CWM and TWRP!)
Reboot to system without clearing (dalvik-/)cache.
The first boot will be considerably slower and after a long wait at the boot animation you will see Android optimizing the apps on your phone and after that, all is done!
I have done this myself, using my own method and I have not found any problem yet, again!
so basically i just donlod these 2 files, flash it with flahtool, then enter twrp then flash C6603.flashable.307.zip right, than reboot, result i will be on .307 rooted right?
my question is what will happen to the existenz rom v3 that i currently using? back to stock?
