in my samsung champ c3303 whenever i try to download games its shows downloaded jar is invalid.. so plz give me a solution so that i can do the same nd play games

i think this mobile can only allow you to play default games.you cannt play any third party games.

hi priyanka, thanx... bt my phn supprt third games also. i have done it b4, bt aftr unlocking my phn nw i fail to load othr games. so plz if can help me...

i hv also same phone . i hd done all process bt the is nt work

first thing you should know that Samsung champ will only install below 500 kb/apps or games.go to the memory test menu on *#52828378#, then tap on Java Heap (KB) change 1460 to 2060 then on MIDP Heap (KB) change 1700 to 2300. Then try to install jar files,you should be done with this process.

additional info ~ ( one of my friend working in Samsung service center told me this process )
if you want to install higher than that just used this code by dialing *#52828378# you will go to Java Test Menu, then go to OTA test, change 500 to 4000 then save. You can now install as much higher than 500 kb but less than 4 mb.

i am seeing this question asked almost regularly in the forums.hope this process can do the trick . all the best
