After looking through numerous posts, I have not found answer.
My phone had a bad imei, flashed to boost, working fine, but trying to do the sim unlock and status shows imei cert fail. I saw some postsa on super imei, but if the imei was changed to the super imei, would it affect the boost flash? Im on mj4. Thanks.

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.
I used my galaxy mega 2 on AT&T's network for about 4 months without any problems until I decide to root it with either Kingoroot or Kingroot and since then i've been network blocked because it changed my IMEI. I want to change it back to what the sticker under the battery says but have had no luck. So far i've tried flashing it using odin and the z3samsung tool. It was 4.4.4 but now it's 5.1.1 KitKat because I can't try to downgrade because the "repair" firmware 4.4.4 always fails. The bad IMEI 350050500009692 i was told that this imei was a default when your imei gets erased by some mobile tool pro via email. I won't publish the good/true imei that's on the sticker. Baseband G750AUCU3B0H4 , Build number LMY47X. G750AUCU3BOH4. Also I get an error when using the z3tool to write NV data, it says "security damaged". Being the bright person I am I didn't back up anything prior to the first attempt but all I need is the IMEI restored everything else seems to work fine. I'm stumped and need help.
Thanks to all or anyone
ME TOO ON SAME BOAT , pLEASE ASSIST ME ON THIS ISSUE
So a friend of mine gave me an s3 with a null/null imei. After a couple of searches on internet i found a custom cp, flashed that cp with odin and got a random imei number and signal but can't register on network. is there a way to modify the imei and insert the one from the back of the phone without needing a flash box. Or to just register the network.
Good day to everybody.
I have 1 problem with my telephone, when i unbrick this, i saw what IMEI, MEID are 0. I changed IMEI, and MEID, and after restart - telephone see SIM, but still have no connection to network. What i need to do?
if the sims are connecting and only the data isn't connecting then check apn

hello, pls how did u rewrite imei, im having same issue, need to fix imei
I gave the same problem. My ESN is 1234567890ABCDEF after flashing. I dont know how tô fix it
Hello.
I couldnt make call forwarding to work, so i thought it was modem.
I flashed modem and fsg and now there is no signal, no sim, no imei, only baseband.
I installed custom rom and i got sim and signal, but still no imei.
I flashed efs backuped imei qcn file, still no result.
Now i reflashed original miui with miflash tool there is no sim, no signal, no imei only baseband.
What should i do, is my phone hard bricked? I cant use imei changer either because this phone is old and i already threw out the box that got imei numbers on it.
Update:
I can forward calls even if phone says there is no sim or network, but i cant use data, or call from the phone.
There were guides on miui forum but they closed it. I still hate xiaomi for closing forums.
