My Xperia SP C5303 just got rooted, but the I updated it to the latest firmware (.266).
Then I noticed that SuperSU can't start because it lost the SU Binary after the update..
I used DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip to root my device, but before that I flashed it with XperiaSP_C530X_12.0.A.1.257_KernelOnly.ftf.
So I tried flashing it again with .257 kernel so I can reinstall SuperSU, but after flashin it only displays the SONY logo and doesn't even get to FLASHMODE or FASTBOOT..
Please help, I need my phone back...
