Galaxy tab firmware issues, please help


Feb 7, 2011
Hello, new to the forum but not to android. Baught my g-tab a while back, loaded euro firmware jk5 and proper modem. Have been using it for quite a while. Problems come up with email and messaging. FC on many apps and lots of lag. No stranger to root ing and custom roms but want feed back before I do a re'n're. Running cashe clean and try not to app kill too often. Is there a more stable firmware or any other ideas. Thanks.
