that bad-locky user is me !!!!!!!!!!!1
i had same problem and searched on google , all the lines , the the topics and ask from most of developers on xda !!
but no one knows what is the problem .
i don't want to tell the story again , but just want to share with u , the problem is cause of the new modem ( or baseband ) !!
my sim card worked like charm on 4.3 ( my baseband was MJ7 ) , but after upgrated to polish 4.4 , after restart my phone this f*** error appear and is waiting for me to press " ok " !!
please be informed that no way back to 4.3 !!!
, and this error will be remain on all custom 4.4 that are available on the xda , cause all of them are based on NA6 ... so all of them have the same baseband !!
plus , don't try to flash any 4.3 baseband on 4.4 , i did that before and (( thanks god my phone is still alive
)) i thought my phone was fu*** up !! every time i rebooted my phone , it had rebooted twice !!! first time came up with the error and after 3 sec it rebooted by itself and come up without error !!!!! + sometime it shut-down by itself ...
actually , this problem will not resolve with any reset , factory reset , clean install , wipe cache ...
so we should wait and crossing or finger to receive our region's 4.4 .
I'm on Iran , as u may knows my country is on global sanction , so i bought my phone from Dubai and sumsung added my language to dubai version MJ7.
i should wait for 4.4 update for MJ7 modem . but i'm confusing , why all of 4.4 modems are NA6 till now ? what should i do if Dubai receive 4.4 NA6 update instead of different modem !!!
-please share with me if u find any other solution . thank u
-a question , what was your previous baseband ? and what is your new one ?
-put your phone on airplan and restart your phone , do you still have the F*** error ?
