A colleague of mine bought an S6 from an ebay seller and it has been working fine for about 2 months, then the weekend before last for no apparent reason, the phone lost its IMEI.
The phone has never been rooted, and when he first got the phone we checked the phone with the "Phone Info *Samsung*" app which indicated that this was a genuine non-refurbed device.
The original IMEI started with 359800, but now it's reading 35(and a lot of zeroes)
Anyone have any idea how this happened and if it is recoverable?
Is it possible that this was a cloned device with a fake imei and somehow that has disappeared?
It just seems strange that the IMEI would go for what seems to be no reason at all

I'm having problem with connecting my phone new phone (nexus 5 from some shop in China) to 3G. only the 2G is working.
I tried almost anything but still couldn't find the problem that cause it.
I suspect that my IMEI was repaired (I have 2 different IMEI numbers in the back of the case and inside of the back case)
I found that after repairing the IMEI with Octoplus they say that "3G network will become unavailable", How can I check that this is really the problem? And does it can be repaired?
Thank you!
Hello all, this is my first post and also please move if in wrong place.
I have had a off the shelf, not locked to a network Samsung Galaxy S2 I9100 for a couple of years now without issue except that it would take sometimes 5 minutes to join the Orange network and get a signal, other times it might be a minute, or then it might be on the network as soon as the phone booted. I just lived with this "little pain in the bum" problem.
I rooted the phone so I could remove un-needed pre-installed apps, to free some space, which worked, but I already had the signal issue before this so I don't believe this made it worse. Last few days I sold it on ebay to be told by the buyer that it would not connect to the network no matter what sim was installed. I now have the phone back with a view to fixing the problem. They basically were not waiting long enough for it to connect to the network, which is fair enough as it should connect quickly.
I have used the following sims, all connecting to the network eventually: Orange, O2 and Vodafone. - This is the same behaviour as before I sold it but just lived with it, but it is clearly a problem.
My findings are that when I first turn on the phone and *#06# the IMEI is null / null. Leave the phone and it will show the REAL IMEI which is printed under the battery and once the IMEI is shown, it will connect to any network. So I don't think it is a fake IMEI problem as it will find the real one. I have also always had a issue with GPS being very poor.
I have tried to backup / restore the EFS folder but it made no difference. I unrooted to the stock ROM before I sold it, re-rooted etc but nothing changes. The IMEI eventually is found and the phone works without any issues.
Hopefully someone will have an idea of where to start to try and fix this issue.
Many thanks in advance.
Woosh
I have also found that the baseband version is also not available to start with. Everything happens together, the IMEI number, the baseband version and connection to phone network all appear to happen at the same time.
I have just re-flashed to stock rom with no change to the delay in getting the IMEI etc. KIES also does not recognise the phone until the missing details are found and then KIES is happy.
Anyone?
So I bought a Note 4 from someone from craigslist and checked the IMEI on T-Mobile's site and it checked out as OK. I went straight to T-Mobile and activated the phone and they even ran the IMEI there too because I told them I bought it off craigslist and they offered me insurance. So I have been using the phone for over a month and I ended up cracking the screen but it still worked and the next day my phone started saying "No Network" and when I called T-Mobile they told me the phone was blocked by them due to non-payment.
So I have a few questions.
If the IMEI checks out on a phone and then they stop making payments a month later how are you suppose to buy a used phone safely?
If I make an insurance claim and they send me a new phone, will that phone be black listed also?
Bump
Hey everyone,
I've looked around the forums quite a bit and have found some similar problems but have not yet found a solution to my scenario.
Basically, my S6 Edge received minor water damage, enough to cause corrosion onto the motherboard through the volume and power buttons.
The phone was inoperable for about 12 months (I was travelling and didn't have the funds to repair it), I've since returned home and decided to fix it.
I took the phone apart, cleaned the corrosion and put the phone back together, I believe the hardware is fully functioning now, everything still works.
Once I turned the phone on it wouldn't pick up a network signal. I went into the 'about' section and found that the phone has no IMEI or Baseband version and it won't recognize a SIM card.
I've rooted the phone, it was originally running 6.0, it's now 7.0 through a manual installation with Odin3 and a factory reset, still no IMEI or Baseband Version.
Everywhere I've read on the internet say I need to backup/restore the EFS files, but that's not the case because they seem to have vanished from thin air.
Other information:
Phone was originally locked to Virgin Aus, I had it unlocked and used it with a Canadian pre-paid SIM no problems
The IMEI is written on the back of the phone
Model is Samsung G925I.
If anyone is able to offer any insight into this I'd be so grateful! I couldn't see anywhere, but can I load a generic EFS file onto the phone and manually enter my IMEI number?
Thanks!
Hello,
A few months ago, I've bought a second hand Galaxy S7 from the UK (via eBay). I'm in Belgium, the phone was unlocked. I ran a few tests, the phone worked fine and I*installed LineageOS 16 (this one:*<https://forum.xda-developers.com/galaxy-s7/development/rom-lineageos-16-microg-t3921094>).
I've just notice a few weeks ago that the network was not as good as another SM-G930F (with the same ROM). In well-covered areas, it seems fine, but when moving (on a train…) or when in remote location with medium or bad reception, my phone lose all network.
I've tested it with two SIM cards (two different operators) and it's the same result.
I've also noticed that the IMEI and SN on the back cover of the phone are different from those in the system settings (and via *#06#). I asked the seller and he told me “We are sorry to hear that, it may was broken and we have change it with another origins back from another phone, the main number is the one in the settings.”
What could I do to try to improve the network connection?
Should I be worried about the IMEI/SN change?
Thanks!

The phone has obviously been re-built from different parts of S7's, the antenna may not be seated correctly or even damaged. The S7 is not designed to be taken apart by re-sellers.
IMEI, Yes it is illegal to change an IMEI number of any phone. You've been sold a dud phone.

Thank you for your reply. I guess I'll try to check the antenna. This issue aside, it kinda works well…
Is there a way to check IMEI numbers before buying a second hand phone? I've just searched online, but there's too many sites, most of them not free, and I don't know where to begin. Is it country restricted?

Is there a way to check IMEI numbers before buying a second hand phone? Yes there is a free network provider website in most countries to check it's valid and you can check on Samsung website. Don't pay any money to anyone! If an IMEI is blacklisted or reported stolen the phone will not register on any network.
Yours is working so is fine.
