[Sony Xperia P, U, Sola, Go] Rrrr:
Ok, thanks.

I assumed what you write "update the latest NFC firmware" was to connect to wifi and download an update. My bad.

But I am no succeeding to get into recovery.

Here is what I did, I followed your instruction:

1. Flashtool, connect USB phone with volume down key, click flash, select flash mode, flash world image (log below)

2. Power on phone, set language, check USB debugging and Unknown sources. Power off.

3. Flashtool, connect USB phone with volume up key, click flash, select fastboot, click select kernel to flash, flash boot.img from CM rom (log below)

4. Disconnect and manual power on from here (I also tried Click Reboot device into system)

5. Phone vibrates shortly

6. Sony logo and other logo shows (screenshot attached)

7. I repeatedly keep pressing many times the volume up key

8. nothing happens, the screen with the logo's is frozen.

I switch off, by pressing power key and volume up key simultaneously until 3 vibrations.

And then I tried again. I do not manage to get into recovery mode.

Should I install CWM recovery manually?

Awaiting your valued advice
