Okay,where do I start.
So I bought this phone off a friend of a friend(I was going to sell it on for profit as it was a good deal).
I noticed when trying to update that it was telling me it was an unauthorised software, so i took it the device was rooted.
I then factory reset the device to see would it go back to factory settings, but just stayed on the custom firmware.
I then decided to flash stock firmware onto the device from Sammobile (device boots up with Three logo so I assumed it was with Three Ireland network so that's the firmware I chose.
After flashing the device it boot up with a dm verity error and would only go as far as the Three logo. After some research I found a discussion and followed the steps in this, flashing a file called CF-Auto-Root-zerolte-zeroltexx-smg925f. After doing this the dm verity error had gone and the phone booted up fine.
I left the phone like this, as I was going to sell it at a later date. Before I sold it I had one last test of the device and noticed it would not connect to a mobile network (I don't think this issue was there when I first got the phone as I am nearly sure I tested my sim card in it, but cant be sure). I just kept getting 'not registered on network' error.
After some more research I downloaded the Samsung info app and ran it. I then noticed a few strange things.
1). The serial number of the device was just showing up as a string of 0's.
2). The imei number that was listed did not match the imei on the back of the phone.
3). The carrier was showing as O2 UK, but Im not sure if this is an issue as O2 and Three are basically the same network here in Ireland (Three took over O2 here).
After doing an imei check, I found the imei listed on the back of the phone to be fine and was showing all the right details, serial number etc. But the imei that was listed as the imei of the phone, in settings and using *#06# was showing up as not existing.
I found this very strange and I'm sure this has something to do with why it can't connect to a network.
Any suggestion on getting this device back working properly as it is just a paperweight now as it is, and after spending money to buy it so I could sell it on I don't want to have wasted that money for nothing.
Any help is appreciated.
Thanks
Nothing? ?

Yea, this is the exact thing thats happened to me (Indian version).
Fresh out of the box phone, worked fine for the last 3-4 days.
Now I'm out on a vacation, and the network selection on roaming was flaky, I was toggling the network selection manually/automatically a few times to get some network, and the next thing I know I no longer have a IMEI (shows unknown) , and the same for baseband ( shows unknown) .
Tried factory resetting , etc, not helping. Will get back home and have the phone repaired/replaced.

This airplane mode sounds dangerous. Unfortunately it may be a necessity when you are travelling etc. Hope there is a known fix or one comes out soon. Until then I will keep my /efs partition backup in 3-datacenter redundant storage place along with my laptop and ext.hdd.
i just recieved an sgs2 in uk and it has this exact problem out of the box.
grrr
if anyone wants to point me to a stock rom for it i'll try flashing it
erm, i dont think flashing will help here.
I reckon that missing IMEI means the /efs partition has been wiped out/corrupted, and that is something which cannot be restored by a simple flash.
finally, after almost 12 days, lots of running around, I finally got my S2 working again.
The service center had to send the phone to their head office since they hadnt received any service info on the new model till then.
They changed the PBA apparently , and finally reflashed it and gave it to me.
They claimed that the flashing was an online process and samsung india service servers were down for nearly 2-3 days, accounting for the additional delay.
Just like my I9000, but I dont think it is the same problem and same way to solve.
I rooted the devise and deleted the nv_date.bin and the nv_data.md5 in EFS file with Root Explorer, and renamed the .nv_data.bak into nv_data.bin, then restart, problem solved
I have exactly the same problem as you guys are talking about. Really weird. The /efs directory, where is it located? Is it located in the main "Root" or is it in a specific folder? I would like to try the thing with the rename trick?

Hi,
I'm pretty new to this forum, i hope some experts in here and explain to me this problem that i have with my S6 Edge. I bought the phone online for my brother, it worked fine for the first three month then somehow, it got blocked . when i check the phone, the IMEI from the setting menu is totally different number from the back of the phone. I tried to reset the phone, reflash with original firmware but still doesn't work. Can someone explain how this can happened? i checked the IMEI from setting menu, it said the phone is black listed, but the IMEI from the back of the phone is still fine. it's a bit weird.... Thank you
Probably original imei has been blacklisted, old owner has changed it and now this on got blacklisted again
Hello everyone, I'm a desperate noobie here trying to fix this issue for three days now.
So as stated above I have a Samsung Core Duo (SM-G335H) and three days ago I connected trough SmartSwitch and it offered to update my phone. I agreed and during the middle/second half of it my laptop and phone just crashed. I revived both and SmartSwitch told me about the update failure and I made an Emergency Recovery. After that recovery, at first, everything seemed to be working normally, but on the next day I noticed: "Not registered on network " error. It recognizes the SIM card, but when you try to find a network it says "Can't connect. Try later." and so on. I can't call, other peeps can't call me.
I have been researching this matter for days now and am very upset about this. Some say stuff like Odin/flashing/third party tools/settings, I don't know what to do, as I don't have much experience with those things.
Btw, my IMEI is not null, it is being displayed (so I guess the EPF folder is not damaged). The APN settings (I'm on T-mobile) are still there, I don't know what to fix about them.
I am running 4.4.2 KitKat and my Security Patch Level is dated 2016 if that is of any relevance...
I also did a hard reset: nothing. SIM card works in my other phone, so it's not damaged. I just now saw that the end symbols in my Baseband version and my Build number don't match. Could that be it? I've seen people recommending updating manually/flashing with a modem file. How do I go about this?
Also: my phone is rooted. Only that I very clumsily attempted it months ago and before this matter here I would have problems with binary updates and what not, "phone is not rooted completely", I already fixed that issue though, it has SuperSu on it.
Anyway, I may have messed up somewhere along the way leading to this problem.
Please don't recommend me reseting/rebooting the phone again or just re-inserting the SIM card, that doesn't fix it.
I welcome any other suggestions, I hope somebody can help me.
Hi, i have bought G977N and later came to know that its IMEI is tampered to get registered on the local networks. it was working before i upgraded it to G977NKOU4CTG1, the original firmware was G977NKSU2BSL7. After upgrading it did not register any of the networks. Got it checked from software expert he told me the network patching done with tempered imei was damaged and now there is no way to do it again on new version G977NKOU4CTG1. I tried to flash G977NKSU2BSL and also the factory firmware of android pie but ODIN get stuck at BOOT.img and download screen shows non-supported version. Can any one help to restore my original IMEI and will it work.
The IMEI ( read: International Mobile Equipment Identity ) is a unique numerical identifier ( 14-17 digits ) for every mobile device what helps to differentiate each device from one another. If you take your phone in for repair, they will track it using the IMEI to distinguish it from the other millions of phones, for example.
IMEI basically has nothing to do with phone's local network settings at all. But it may be used to unlock a phone on certain networks.
The IMEI is stored on phone's /EFS partition and/or /EFS folder. If you didn't backup that before flashing you have lost, IMO, unless you still have the box in which the phone was delivered, because there is usually the IMEI printed, too.
I don't have the box of the phone. The seller has tempered the imei to get it registered on the local network. I didn't backup before flashing. Now what to do. How to downgrade to previous firmware. I tried to flash the previous firmware but it stuck in boot.img.
They told me solution is available for U3 binary but no solution is available for U4 binary.
Awaiting for help on this issue.
You should have returned the device. Since the imei has been tampered with you will not get much help here. Imei changing and tampering is illegal in most countries. And it's not discussed on xda

I'm guessing you also bought a tampered IMEI device. Take it to any local market where there are plenty of phone 'software repair' guys. Ask them if they have Chimera or z3x tool. They'll fix your problem for ~800 PKR.
Remember, if you buy such devices, don't flash anything on them. Every time you do, you'll need to go back to the same software guy and pay him to fix your signal issue.
=========================
For other people reading this comment - Yes I understand IMEI tampering is illegal in most countries. The reason people in Pakistan buy these phones is because the government has levied unreasonable duties on all imported devices, without any consideration for the age/condition. For example, a used/refurbished S10 that costs you 250 USD in the US, will have custom charges of about 250 USD applied to it if you want it to work in Pakistan. So basically you pay double.
I have this same issue somtimes the signal comes and somtimes it doesnt.

Hi all,
Alright so this is going to be a long post. So I recently flashed my phone to the U1 firmware, I currently have an unrooted Verizon Unlocked Samsung S9+. I wanted to switch phone carriers over to Visible (subsidiary of Verizon), here are the order of events that occurred:
1. Visible's website says that my device in not compatible using their IMEI checker, there is a solution that was found on reddit about flashing the device on the U1 firmware.
2. I flashed the device on the U1 firmware using Odin and the Visible SIM card worked as expected. No issues with the flash
3. Data/Texts etc.. are all working as expected. Except for Voicemail.
When I try to check my Voicemail, it is acting as if it's still on the Verizon Voicemail system. It says "Welcome to the message management system, please enter your mailbox number". No one can leave me a VM either because of this. I tried several different combinations of numbers, including my full 10 digit cell number and last 4, to which it says "XXX is not a valid mailbox number", which would be because my number is no longer active on Verizon, so it's unable to access it. Which makes sense. The Visible Customer Care team tried the following:
1. Provisioning my VM multiple times
2. Take out SIM card, turn phone off for 1 min, insert SIM card again, and toggle airplane mode for 30 seconds
3. Reset network settings
After numerous days of troubleshooting with them, eventually they said it was because my device isn't compatible, ok, I can't argue with that. I have not seen anyone else experiencing this issue that had flashed their phone to U1 firmware.
After trying all of this with them, I eventually factory reset my device, hoping that might do something. That still did not work.
My questions is, is there something I missed with flashing the U1 firmware? Why is it still using Verizon's VM system even though I flashed it to U1? Is there any way to fix this? Any help is greatly appreciated, and please don't hesitate if you need any other information.

Please check your voice mail settings in your phone app. See my screenshots.
There you should select the correct service provider and the Visible mailbox number.
