No mine worked normally but I never updated for fear of losing r00t.
I suggest going on xda or Rootzwiki forums, and finding out if there is anyone with the same phone as yours (kernel ##). See if they have a nandroid backup and flash that with CWM.

It would hopefully get you back to the start. Then you have to follow these steps:
-root + cwm (again)
-install Titanium Backup
-backup all your app + data & SYSTEM DATA
(the keyboard will be a system data)
-flash to any custom rom OR do official update
-(if lost) root device again
-install Titanium again
-restore your apps with data, and your SYSTEM DATA


I've got the latest ICStunner 1.4.19 on there, at last a good performing AOKP ROM ! I've also got MIUI running (Beta V6), not bad for a beta, but somewhat laggy and buggy. It will be sweet when MIUI gets their **** together and a proper (high quality) one is released.
