  still can't get it to work still 'emergency call only' .. maybe use wrong method or wrong file

currently AP : I9300XXEMF6
CP : I9300XXEMF6
CSC : I9300OLBEMF3

for those who have problem with 'no network''emergency call'or whatsoever flash this stock rom with odin
http://live.samsung-updates.com/details/13...9300XXEMG4.html

its md5 file put it in pda

Kernel file is the software driver that manages your phone cpu...

After download I flash using odin 'PDA' , after that boot into recovery factory reset and clear cache then restart .
should be fix , see ur imei is it there or becore other number

first follow what wilsonjack228ask u to do...if still emergency call pls check your imei? .....if not change try make new apn in network setting...

Did you lost your CSC..?
Check via dialler *#1234#

imei still original or 0049?

Does your phone rooted..?
If rooted..try use SGS CSC Flasher app from market and see if you can change your CSC

imei still original or 0049?

Instal Root Checker app and see if your phone rooted or not.
If rooted...try use SGS CSC flasher to change your CSC.

If not rooted..try flash latest full stock M'sian firmware via Odin.
If you lost your imei or data connection..then flash that EMG4 modem.

Have you try flash EMG4 modem..?
Then go into recovery mode..wipe data and cache.
See if you get back your imei..

If still no imei and data network...reflash again the full M'sian firmware and I'm afraid you need to bring your phone to service centre. There..they will properly reflash the correct way.

flashing mg4 didnt help?

then probably gone case like mine...

i have efs backup on older version, i flash new and old rom and put back tht efs it didnt help...

even flash a mg4 rom with pit, bootloader, pda, phone and csc didnt help...

Dun panic , flash the modem from the link from prrvious post the xxemg4 modem , then factory reset and clear cache . Then reboot and see

http://forum.xda-developers.com/showpost.p...65&postcount=15 try this , the zip file

unzip the files and take the modem section and put at phone in Odin

dont send it first try my last solution...hope it will fix yours...if still persist then ssc is your place

Thats weird , all same with mine . Did you try with other sim card or phone?

pls go the settings》more settings》mobile network》access point names (any apn setting in there)..give me the screenshot

u should try this
Open your phone’s dialer and type the following code
with your device IMEI number: *#272*IMEI Here#
