i was able to flash CNA 1.3.3 successfully from Gamerz Rom v6.5....yet i wish to know why i had that error....coz i take all precautions and that error wreaked my entire day
THANKS to everyone who help
Finally i wana say, dnt try cm roms as those roms doesn't work always either cm7 or cm9. i personally on jvu rom which is latest samnsung rom and didnt tried cm, use any jvu rom from any dev like gamers rom, simplicity(best n full featured rom which i m using) all will work gud cz devs only modify ui and do some tweaks so there is less chance of bugs as compared to cm roms cz they modified core or rom
