But on the 2 day night ( that is 3 days ago ) i try to update my Twrp 184.108.40.206 to 2.5 by Mobileuncle mtk tool.. that did not got upgrade.. thats fine but from that restart my mobile says " Sim card 2 not detected " " Sim card 2 not detected" .. baseband version unknown, IMEI number invalid.. I tried re-installing this ROM, S4 ROM, 4.2.1 by back37, ProjectDoge_Final... but same error on all this 4 ROMs.. wifi is working, BT working, rest all working.. only sim card not detecting. Then i try to put my Stock ROM which was by default mobiles out of box ROM ( 4.1.2 ). i took that ROM backup in twrp while putting 1st custom ROM.. and after restoring that ROM from twrp sim card working fine!!
