[Q] how to restore IMEI on galaxy nexus

I got a used galaxy nexus which wasnt factory unlocked but the owner unlocked it. Now i have a generic imei and want to restore it.
Oddly i cant use the.phone on its original carrier but any other one. I think the problem is the generic IMEI but since i got it from some one else, they didnt make a back up of the original imei file so i could restore it. Im really frustrated and will appreciate any help. Thanks

You can find a shop with an SPTBox and the will do it for ya

Hey, i did what you said, indeed its restored. Now my main concern is if flashing custom roms affect the imei number. I dont want to mess up things, thanks

Simply put, Sptbox is hardware + software solution that allows write access to system partitions that aren't accessible otherwise. In this case, the EFS folder

i can not find sptbox toolkit here

Sptbox isn't here, and it's not free either. You have to buy the box and the software that goes with it. If you Google it, it should come up with better results.

someone could told me what are the default generic IMEI used on gnex??? I want to try to make them unavailable in my country if they arent yet.

I have restored mine with na octopus box and uart cable. I had to buy the box with Samsung activation + uart cable.
For me, it was a good deal because I will use the box for many other purposes. Ig you wanto to buy the box just to restore your IMEI, it might be too expensive.
Just Google it and you will know what we are talking about.

004499... is a dummy imei if the phones imei is messed up.. something wrong with efs (I have little knowledge about it but a search for efs backup will have many hits in the forum)
It happened to me and the what solved my problem is installing an old modem software on the phone.

thank you bro, i brought it to service center

IMEI : null , please help

hello ,
yesterday i woke up to find my note2 not working saying insert sim card
and when i tried to check imei it says null null
i never tried to install rom or root my phone , i just bought it 2 weeks ago
i've searched all the forums and found that people only get that error when they try to flash their device but i didnt .. it just suddenly happened
would you please guide me to fix it ?
my phone is galaxy note 2 N7100 and it has 4.3 jellybean

I suggest you to take your phone back. I think it is a hardware problem. You can do nothing for that. If your phone was rooted and has a backup of your original efs partition (IMEI) only than it is possible to recover your IMEI.

that phone was shipped to me from dubai and it has no warranty .. i cant do that

Oh thats bad. You must find a service who has good knowledge about Android phones. Did you checked your phone after you received it. Maybe the phone was without real IMEI. So far I know the GSM prowiders allow a couple days to use your unregistered device.
Sent from my SM-N9000Q using Tapatalk

hmmm
well thats bad
you haven't tried to root and flash custom rom at least if so if u have tried it is possible you might lose imei and which is why it is advisable to make an EFS back up.it could be a hardware related problem..try taking it to the samsung service center they are the ones who can really help you.

Try this solution: use Root Explorer enter to EFS folder, delete NV_DATA.BIN and NV_DATA.BIN.MD5. Reboot your device and check imei.

If device is shipped with broken seal on box then...
It's stolen by someone & sold him online.
& I think someone(frustrated Owner) knows & banned his IMEI via complain.and that's why he got null error while no reason at all.
It's just a guess.

Lock in eBay, offer the remote imei repair

Since you're rooted, Samsung won't even reflash it. Sucks.
S6 Edge

The only way for a user to restore their IMEI is to have done a backup originally before attempting to do any changes.
You need to take the device go the carrier for repair.
Altering changing or manipulating IMEI numbers on devices is illegal in some places and not something allowed for discussion on XDA.

Help with ZERO networks!! Before I burn this THING!!

Okay story so far, got Zuk Z2 from BG China to replace Mi5 that had a tumble
After a couple of weeks I decided to flash Custom Rom (LinageOS *UNOFFICIAL), seemed fine then I lost Network totally on both SIMS.... Zero bars! I've tried all sorts of ROMS and flashes of Baseband firmwares but to no avail. Now I think I've confused myself.
So if anyone has any advice before I cast this device from a high roof it would be most appreciated.
Thank you :good:

You flashed already different basebands via fastboot, erased modem after that?
Tried flash stock ZUI via qfil?
After all no network? IMEI's are there?

When it first gave up network I checked IMEI and it seemed to have duplicated them for both sim but after I QFIL back to ZUI 2.5 they returned perfectly... I've gone through the whole erase modemst process but still FUBAR....
Even stripped the device down to bits and checked the internal connections.
He strange part is I get the emergency only msg on sim so guessing the network is recognised but the signal is -90 dBm at best, getting to as bad as -130 dBm.
Even considering writing the IMEI from old bust Mi5 to handset to see if this would help...

Yeah I guess every other android and iOS device I've either rooted or jail broke was pure luck and the huge amount of posts on many sites including Lenovo regarding this baseband problem are all very similar 'lab rat' experiments.
Thanks for the constructive advice and answering my plea, great to know that xda developers are attracting helpful and intelligent like minded users and owners....

I had a dabble with QCN and managed to replace corrupt IMEI's but still didn't help. Can't be sure the BASEBAND was correct though.. I'm yet to try a full FACTORY DEFAULT configuration as suggested but will be this week.
Been suggested the IMEI may be blocked for some reason but seems unrealistic as it was working prior to FLASH.
