Xperia Ray ST18i - CWM - install zip from sdcard, error message: This package is for "ST18i,..." devices; this is a "".?
I found an answer here:

Edit the updater-script, but don't try to fix it - remove the condition altogether since I know I'm on the correct device.  

Thanks adulfo!  

PS. bizarrely, after powering down, when I returned to recovery, a different version (6.0.5.1) of recovery came up rather than 5.027.  Possibly x-Parts had improperly installed CWM, and the second install 5.027 made it possible to access it, because after originally installing with x-Parts I could not boot into recovery.  (Although that does not make sense either because x-Parts says it installs recovery into the system, and it is erased by flashing a ROM)

Still, I don't know why CWM did not recognize the device as an ST18i (and thereby failed the script), especially since it had done so during the installation of CWM recovery.
