and their solutions.

(If you get any more bugs and solutions please

let me know. I will add them here. It will be

helpful for all.)

These r 

the 

solutions:-

1. FOR NETWORK RELATED ISSUES (3G)

Replace from /etc folder, mddb then replace

agps_profiles_conf, apns-conf,epo_conf, spn-

conf, virtual-spn-conf-by-efpnn, virtual-spn-conf-

"unfortunately camera has stopped"

Replace first libcamdrv.so (needed for 6582

devices) and check if not success then replace

libcameraservice.so from/lib. If still not success

then keep on replacing one file at a time and

check.

Camera problem is the one major bug in this type

of porting. You have to have patience. This will

take half of your energy.
