Do you have a backup of your stock ROM, if yes Reflash it.

Hi Guys
I updated my S3 to a small critical update, not 4.1.2 and it was a OTA update and now the phone will not make a call, it keeps displaying " not registered to the Network" but it has a data connection i am able to surf the net, I have checked and the phone is not blocked or on the blacklist or reported stolen but I had unlocked the phone via Unlocker.com a few months ago.No UK SIM i.e. (Vodafone Tmobile Three) will make a call through my phone
I have
Wiped Device to factory settings
Flashed a stock rom JB I9300 4.1.2
Flashed Custom Rom "I9300_Omega_v4.2_AOKP_Milestone_1_Jelly_Bean"
Flashed my Operator Rom back on
I have not backed up my EFS Folder and would not know how to
Reset flash counter
Now My IMEI number has changed but on the IMEI SV number, on the back of my phone the IMEI number ends with a ***** /09 but now I have flashed it ends with a /06 .... will that cause a issue, The long SIM number has not changed on the phone.
any suggestions please as I fear that if I send it off to samsung they will not fix as the IMEI SV number has changed and will charge me as they will state it is out of warranty

Hi this is starting to really bug me now Im unable to register on a network I get signal bars but only get emergency calls only tried dfferent sim cards and reverted back to latest official stock to no avail any suggestions please
As per multiple identical posts .
First is your IMEI correct
Are your mobile network settings correct
sim card correct and tested
correct modem and csc.

Check your IMEI number. Sometimes, when we flash custom ROM, the phone looses its IMEI number. If it's true, you must use an EFS backup to restore it.
Second solution : your mobile phone was blacklisted (if it was considered as stollen).

Hi thanks for the reply I have been searching I've checked my imei in status and it matches details under battery compartment i'm still paying for the phone (pay weekly) so no reason it would be blacklisted ok just tried another different sim card on Vodafone official s3 stock rom and it registered hmmm im on talktalk which uses voda I know this sim works but i'll get them to send me a new one thanks for your time guys
Yesterday on my way to my cabin my phone stopped connecting to network. I can't call, send messages and can't use mobile data. I tried to which sim card with a friend, but that didn't work. Is my phone damaged or is it just an error on the network?
Sent from my GT-I9300 using WIFI
EDIT: After flashing Xperianze ROM my phone had got the IMEI of a stolen S II in Kenya. Since the phone which had this IMEI was stolen it was blacklisted. So if you find out that your IMEI is changed simply use Kies to flash stock. Then your orginal IMEI is going to be restored!
Use these two links to check your IMEI:
Link 1 - http://swappa.com/esn
Link 2 - http://www.imeidetective.com/
Do check on both sites!
Hi!!:
After reading and reading and trying every method i found on the internet, i still have not succeded with my problem which is this:
I tryed to flash an stock 4.3 to my free s3 movistar chile, but when it rebooted and after i wrote the pin code, it asks me for an unblock sim code
It presented signal but uknown network. I got back to 4.1.2 thinking that it should repair this, but no, it was worst, i got imei null,
After searching and searchingI found a cwm 3 files patch on the internet: one for cleaning kernel, other one to install kernel and the other one to install modem, and with it i got my imei back, (this is when i made efs backup, i know i sould have done long before ) but also the wknown network problem, with the phone asking me for this unblock sim code again.
I used galaxysim unlock to try to repair this, but it showed me that the phone is totally unlocked i think i remember it also showed me the state of csc and it appeared blocked, so i think this is where the problem lies, but i couldnt find any info about this.
when i go to state of the phone i see this
network: uknown
kind of network: umts
service state: out of service
mobile network state: disconnected
imei:3537.... thats ok, fits with the one on the back of the phone
device state: modified
(sorry if my einglish is not very accurate)
So resuming: my imei number is ok, wifi works ok, but even though the phone shows signal, it presents uknown network, and i cant do or receive calls.
i would be very thankful if any of you could help me
Your phone was unlocked using a crack that only worked on 4.1, by updating to 4.3 you've corrupted the efs folder.
You now need to buy an unlocking code and pay for a repair, make sure it works on 4.3 before you accept the phone back.

Thanks a lot for answering!. So, if the phone was cracked in 4.1.1, is there any chance to downgrade to that version, use the corrupt efs backup that i have, just in case i lose the imei, and try to unlock?, or would be too risky?
Not without a backup of the efs before you upgrade, no.
Hi,
can anyone provide me with nvram /nvdata backup please of Ulephone power 2?
I have probably correct IMEI, valid MAC fo Wifi/BT ...
It looks like my serial number changed to 123456789ABCDEF and I have no idea how to change it to original because MAUI (?) stucked on get kernel
I can find original box with correct serial and IMEis on stick
The only one problem with mobile is I am not able connect to mobile network - registration SIM to mobile network always fail.
and at MTK engineer I have only Bluetooth, FM Receiver, Wifi, Wifi CTIA, Wifi Display
I have nothing like Radio, CDS etc ...
OEM unlocked, TWRP, rooted
Some information probably lost when flashing
I had to flash , because phone was unusable - it stucked mostly on obtaining IP address wifi
after a while, phone disconnected from wifi and cant find any wifi or if find, then cant connect because of some security issue , after restart all was OK ...
