1. Upgrade to 10.3.1.B.0.256 (you'll lose root at this point)
2. install 10.1.D.0.343's kernel
3. root using DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip
4. install 10.3.1.B.0.256 kernel
Thx, but my phone's bootloader is locked (as are all Docomo phones). I thought it was impossible to install a different kernel then. Not t mention that some people noted that the OTA upgade doesn't work if your pone is rooted. Haven't tried it myself though.
Losing root does not mean I lose CWM, right?
Edit: So I tried updating it, the update just stops after 2-3 minutes, the phone reboots and I get a message 'update failed, please try again'.
