Known Issues
If you're using a custom MP3/Wav file as a ringtone, flashing ThunderBolt! might erase that setting causing your ringtone to be silent. Be sure to restore the ringtone again.
Barriers are turned off in /data. Corruption can happen but risks are minimal if you still have journaling.
Libsqlite safety_level is tuned to "1" from "3". There is risk of corruption here. Revert the libsqlite*.so files from the restore pack if you face corruption This is due to no fsync is done before databases are committed into disk hence it'll be faster but at the risk of corruption i.e. Launcher widgets going missing or SMS messages going missing etc.
sqlite_optimize script will produce errors like "malformed database" or "unknown collation sequence". It's normal, it means that these databases are not sqlite compatible, hence erroring out (skipped).You may sometimes lose access to busybox. Install busybox installer (stericson's) from the market and install 1.19.3 to /xbin.
Bootup (even to the point where you can see the launcher)may be a little slow as zipalign takes some time.
remount script has to be launched using script manager
Remount script is only for i9000 Samsung, i9000 CM7/MIUI and i9001 + a few others(check /sdcard/bolt_scripts)
CWM zip is only for devices that has /system and /data as its mount points. Remember to mount these in CWM.
The LMK/OOM is on the aggressive side. Some apps that you've hidden behind other visible processes SHOULD be killed to make way for bigger apps. This is to ensure your Angry Birds or Fruit Ninja doesn't LAG LIKE HELL after some time.
