"Original thread"

Hello everyone,

Well, back again with the problem that can't find any solution anywhere.

I've opened a thread about fake imei on this site earlier which can find a solution already. Now the imei and the S/N become original one but the phone still can't make any call. I found the thread about a patch that can fix this issue but it works with NOTE2 and S3 only... so, I'm afraid to try that with my S4 GT-I9500 since it's very hard to find a fix for its problem... I don't want another problem for my phone now...

So, the status of the phone is unlock, root, on latest stock firmware(I9500XXUBMG1), Baseband is I9500DXUBMF8,

Software status on phone: Network=Unknown, Mobile Network Type=Edge:2, Service State=Out of service...

When I check with AndroidDump the Telephony said:

IMEI=(my original IMEI)

CallState=IDLE

DataActivity=NONE

DataState=DISCONNECTED

NetworkType=EDGE

PhoneType=GSM

SimState=READY

CellLocation=[16427,50572,-1]

DeviceSoftwareVersion=01

Line1Number= (it's blank)

NetworkCountryIso=th

NetworkOperator=52018

NetworkOperatorName= (it's blank...again)

SimCountryIso=th

SimOperator=52018

SimSerialNumber= (my sim serial number)

SubscriberId=52018961057xxxx (this is my IMSI)

VoiceMailAlphaTag=VOICEMAIL

VoiceMailNumber=1802 (this is the voice mail number of my sim operator)

Now, let's go back a bit for earlier problem of my phone...

It's been stuck on Samsung logo(bootloop) because of EFS folder corrupted(Error mount efs)

Solution: I forced the efs to mount by enter the command in Terminal Emulator on Recovery mode, then the phone reboot normally with wifi connect but fake Imei(004999xxxxxxx) and S/N 00000000000. So, I can't make any call since then but can connect wifi.

After that with the fake Imei and S/N all zero I've finally found a mobile repair shop that can write the original Imei and S/N for me with the SPT Box. So, my phone has the original Imei and S/N now but when I try to make call it said "Not registered on network"

If I choose the network manually(My operator is DTAC) it will be Network(DTAC)unavailable... If set to choose automatically, it looks fine but when I attempt to call it said "Not registered on network" again...

The phone still can connect to WiFi, as usual... but can't make call...like before fix the Imei and S/N

Contacted the operator of my sim already and they said it seems to be the problem of the phone so, I have to contact Samsung... but my phone has no service with Samsung coz it's the phone from another country and it's been root already...

I've tried every way I can(found on this site and other site...) None work...

So... anyone has any idea why my phone can't make any call???... and HOW EXACTLY TO FIX IT???

Thank you again for you time and help... ;)
