I failed to root my phone using this:
I flashed the kernel from the 1st post (Advanced Stock Kernel) BUT forgot to download and save the SuperSU root ZIP file on my SD card before flashing the kernel.
When I reboot the phone, it keeps looping at the Sony logo.
I've only got 13% battery juice left, and I don't want to slip this up.
I can still access CWM/TWRP (the kernel is dual boot) and Fastboot.
I'm looking for a stock, rooted ZL image that I might be able to flash using Fastboot method. But I can't seem find one.
Someone please help. TY.
I was able to find a solution.
I downloaded the kernel from this:
and the flashable ROM from this:
I copied both ZIP files on my external SD card via a memory card reader, then flashed both files via CWM.
The phone successfully booted.
I hope this thread will provide a solution for others with the same problem.
Luckily, there was still 4% battery left. Whew. Time to charge it up!
