I have a GM1915, the T-Mobile variant of the OnePlus 7 Pro. This phone has Dual-SIM hardware inside, and international OOS supports it. However, it only has one IMEI, which both SIM slots use.
I am considering changing the second IMEI. Based on moderator posts in the past, guides, tools, discussions etc. on changing the hardware IMEI are not allowed. However, I am not asking for guides or tools about changing the hardware IMEI. I would simply like a bit of guidance on how to pick a safe one, for example, for spoofing in software.
I will be keeping the IMEI that came with my phone - only changing the IMEI of the second SIM slot, so that they are no longer identical. There's probably a Magisk module for this. The mod post says software spoofing is allowed, so I assume by extension "how to pick an IMEI" is as well?
Onto my questions:
Is it safe (and legal) to just change IMEIs like this?
Are they assigned by some authority?
How do I fabricate a new one that is not likely to already exist, and is also most importantly legit? (spamming random numbers does not count as legit)
And of course, the two changing options:
Is there a Magisk module out there for spoofing IMEI with dual SIMs? Does it work on OxygenOS? How safe is it?
Is it possible to use TWRP to reflash EFS? Would that actually change the IMEI, or would it brick the phone?
Please do not post any tools or guides on modifying the EFS partition. That is out of the scope of this post and against the rules. I am, however, wondering about the risks of doing so, as well as the risks of using a software method instead.
According to Wikipedia, an IMEI number is made up of three significant sections:
- The first 8 digits are the TAC, which identifies the model of phone (don't change)
- The next 6 digits are the serial number (do change?)
- Then a check digit that must be calculated based on the value of the previous 14 digits
Creating a second IMEI would consist of changing the serial number somehow (help?), and then recalculating the check digit, right?
So in my history I had a set of legit s8s from samsung. From there error both of my s8s had the same imei. I used one. And my neighbor used one. Both of us where on the same network. Same tower different accounts and had no issues. That being said. In my studies if we used it dual sim more than likely the second sim would be another carrier. The dual identical IMEI shouldn't matter. In theory even same network and same device should be ok. I'll have to get a dual sim tray and try it out.

Any info on sim card cloning or a backup image(not just your phone numbers I mean everything that the sim has in it) but doing this with a smartphone.
Is it possible?
Look for a program called "Jeyo Mobile Companion". It should handle what you're trying to do.
i was looking for this but now it seems that its impossible
http://en.wikipedia.org/wiki/SIM_cloning
mods can you delete this thread please
Hi,
I have successsfully clones my SIM and have now the original one and three clones.
Basically you need to extract some values (KI and anotherone, which name I forgot) out of your original SIM. This is done through a Smartcard-Reader (Phoenix-Mode). The software you need is available for free, however all this is done by bruteforcing your SIM.
Recent SIM-cards are resistant against these attacks and will lock themselfs, which makes them useless: they will have to be replaced. When I say recent, that means all cards distributed in the last 5 years AT LEAST!
If you can read spanish, here is the only link you need: http://simemu.cjb.net
Also, if you succed in cloning your SIM, you should always pay attention TO NOT HAVE TWO CLONES TURNED ON AT THE SAME TIME, as the provider will naturally detect the same SIM to be connected twice.
What's nice about this is that you can actually clone different SIM's into on single smartcard and then change numbers/operators, without turning your phone on and off. Naturally you will be connected to only one number at any given time.
Hope this helps a little.

hey all.i have problem with my htc tornado.so i triyed to update rom,and i have "data crashes" when sim card inserted.so what i must to do with my phone?i tried to use any unlockers for that and any ROM's,but it still data crashes.
so what should i do with that?
Here is your answer
As gutek85 already pointed to my post, let me add that your problem has nothing to do with ROM upgrades. ROM upgrades (aka "flashing") have different parts you usually do not touch (Splash-Screen, Radio + Low-Level-loaders: IPL and SPL) and those that you want to change (OS - aka "Windows Version").
None of those are touching the "encrypted block".
When getting a device from anyone, always check if the device can work with your SIM Card. If you get the "data crashes" message - see the post referenced. If you get a message about entering an unlock code then your device is SIM locked.
The Lokiwiz tooling can remedy this problem and (if applied correctly and with care) supply you a SIM unlocked and CID unlocked device.
i was bought this phone and unlock it with code one year ago..
i think its need some soft operation
The diagnosis is 100% sure. If you have the message "data crashes..." when inserting your SIM and trying to get Radio contact, then your encrypted block IS corrupted. If everything was ok after you unlocked the device, why did you bother to do something more to that? What went wrong? I never had problems with lokiwiz - enough written about it in my kitchen post.
Please mind that to my knowledge all tools dealing with unlocking (lokiwiz or wizardunlock, which does not work on my Tornados) are reading the whole encrypted block (just 64k), modify something inside (either remove CID lock or remove SIM Lock - some even claim to change the IMEI) and then write back the whole block. So if anything goes wrong to the things these tools are writing in the encrypted block, your only way to get back is to restore the original block. If you do not have it any longer - you are lost if on your own. You can play around for hours or days (and fail) or pay 10GBP to the imei-check.uk guys and you are done - your choice.
Luckily you can still use the device as a WinMo music player or alike - just GSM Radio will not work as long as your encrypted block is broken.
i can pay 10 GBP...they send me block's or they send me code only?
look it up here: http://imei-check.co.uk/c600_unlock.php
C600 is one of the many Tornado variants - it will work for you as well.
Is it posible to write backuped encrypted block from another Tornado phone?
It could be a solution for people like kviaff...
No it does not work - you can try (if you backup the original to restore later). It seems that the IMEI (read with *#06#) is taken from another (hidden?) place and it must match the one stored in the encrypted block.
This is why the "data crashes..." message appears! The IMEI do not match. I had received such a wrong written Tornado board (from AlainL - we had a thread about this here in the forum, in my kitchen thread I believe) and it could successfully be recovered with the imei-check.uk method (paying them, of course).
Mind that the lokiwiz will not take care of existing lock-backup.bin files in its directory. The next call to any option will overwrite the previous. It could be safeguarded in the batchfile (for those who are batch wizards), but you can rename this yourself before calling the next option.
What if I change my imei (with Wizard Service Tool) to imei of the phone with corrupted encrypted block and then create backup? Maybe it can help fix problem...
Well you are the only one that has reported that the Wizard Service Tool works on the Tornado - and only with the 6.5 ROM from SGregory.
I don't know what actually these tools are doing in detail to the devices - and time as well as effort to investigate on this is not worth it if you just shell out 10 GBP to have it working again.
You would also first need to find out which kind of corruption the encrypted block actually has. It could well be that a non-matching IMEI is just one of many reasons to issue this "data crashes..." message (it was for me - as reported).
You should know (you do, I think) that changing the IMEI is illegal and you must obviously obey the rules how an IMEI is constructed. So why bother with all this?
kviaff must discuss what he did to the device with the guys at imei-check.uk and ask them if their procedure will recover it. We can only guess here as he did not tell how that happened to his device yet.
I know, that imei changing is illegal, but in situations of service it's legal. Similar to Windows Mobile modifications (you know it, I think) But back to the cost of reconstructing, 10 GBP is enough money to fix it by myself. In Poland i can buy SPV C600 for equivalent 15-20 GBP (in good condition) so it's uneconmic
I have one reserve C600 so I'll experimented with it (I'll make a backup copy of course) So wish me luck and of course will inform you of the results
By searching for something else I found this blog and finally also this XDA thread. I have not checked the tool yet (maybe will never do) - but in case anyone dares?!
Possibly the data-crashes goes away if everything is re-constructed in the encrypted block for a new IMEI (or the original one)? Should have found it in January this year when I payed IMEI-CHECK.UK the bucks to recover a Tornado board.
I'll try it and write if it works with "Data craches..." problem

I can vouch for the fact that Wizard Service Tool works on Tornado. I had Super CID unlocked my mob using some other method and then while doing some random stuff, had changed the IMEI to something like 000..123..90 or something just for fun's sake. Then a few months later, India passed a law which made phones with invalid IMEI useless. So, I had to use some software to recover my IMEI from a memory block, forgot which one I used ( I had erased the IMEI off from the surface below battery due to another freakish accident ) Then I used WST to restore my earlier IMEI.
Most probably you have loaded the WM65 ROM from Gregory - there it works and the "data crashes" message is suppressed (by the ROM). The corrupted block would not work with any other ROM and the WST would not work with any other as well.
At least these are the conclusions from gutek85 so far.
Mind that the WST is not the IMEI changer for the wizard!
It's posible to read original IMEI from (original) CID block with WST.
CID Action => Read CID block
Ok, finally I tried the IMEI change Wizard on one of my spare Tornados. Result is:
it works in changing the IMEI, if the device was ok before the change then there is still no "data crashes" after the change
it should NOT work in getting rid of the "data crashes" message because obviously the encrypted block is not linked to the IMEI of the device but to a HW characteristic of the device itself.
If I remember right (when searching for a solution for my old "data crashes" PBA) the encrypted block is linked to the Disc-On-Chip-ID which is HW unique per DOC in each device. It cannot be linked to the IMEI because otherwise a change of the IMEI would have created the data-crashes message. I have checked if the encrypted block is changed by the IMEI Update Wizard - and it is not. It is still possible that the "encrypted block" is extending beyond the 64k that lokiwiz is backing up.
So it is a nice tool to play with but has no real purpose for those who are legal owners of their devices. There is plenty of information regarding the consequences of changing the IMEI (legal and technical), so let me pick the simplest: If you change your device type (the first 6 digits) then the network may treat your device in a wrong way and you could experience strange behavior of e.g. MMS or configuration messages.
If you pick the IMEI of an existing (and connected) device you may bring the legal owner in problems - not only yourself.
For the curious:
In the scope of changing the IMEI the tool reads (and decrypts?) a block of 16k. It saves it temporarily in its program directory under "pdocread.dat"
after change (before write back) it holds the changed data there as well. For the Tornado you see that the IMEI is stored at offset x'300C safeguarded by some checksum at x'3008.
Mind: "IMEI Change Wizard" is NOT the "Wizard Service Tool (WST)"
I also finally succeeded to make the WST run with a stock WM5 Tornado. You have to manually add one policy setting:
HKEY_LOCAL_MACHINE\Security\Policies\Policies
add there a DWORD "0000101a" and set it to the value "1". This is what the "Cert_SPCS.cab" does but this will run only on PPC devices and not on a smartphone. Not sure though which of the operations from the WST will actually work on the Tornado and which will kill the device in one or the other way.
Good job
So there is still no way to fix Encrypted Block for free... Maybe someone could crack IMEICheck tool for avoid keyfile or make keyfile generator I tryed, but haven't enough knowledge...
I flashed to Froyo 2.2 leaked the day I got my phone and never even knew about device ID. What does this mean for my future

You can always flash back to stock using the following method (see link):
http://forum.xda-developers.com/showthread.php?t=731989
Once you flash back to stock, write down the ID and then do as you wish. This is the only way I can think of right now in order to get your ID. However, I thought the Froyo 2.2 leaks only changed the Android ID and not the device ID. But in any case, you can always go back to stock and write whatever information you need down.
Yeah, the problem is with the Android ID. After flashing 20+ times now, I decided only 2 days ago to save my Android ID when I flashed back to JF6. Before then, I was running with the incorrect Android ID or randomly generated ID without a problem.
And the way I ended up getting my Android ID was flashing to JF6, and downloading the app "Android ID Changer" (no root required just to view your ID)
I still have a backup copy of my JF6 settings.db file on my computer from when I first enabled sideloading. Just so happens, it's also my backup of my Android ID.
So just a thought for everyone else who comes around this thread for whatever reason, if you have a nandroid backup of your 2.1 rom, just dump the data.img file and grab your settings.db, open it with your favorite SQLite editor, and nab your Android ID out of it.
Ok, let me make sure I know what we're talking about. I flashed my Captivate to the leaked 2.2. It's rooted and lagfixed.
So, in doing so I've lost my device ID? How does this affect the phone? I haven't noticed any differences.

You may have periodic market problems. There are some games that may not work.
If it is working ok for you then go with it for now. When you are bored with what you are on and want to change roms you should and probably have to flag back to stock. St that time you can readily retrieve your id using app android id changer
Sent from my SAMSUNG-SGH-I897 using XDA App
i had an issue where even flashing back to stock one click wasn't rest IMEI or ID (also had changed my product code to tmobile.
Regardless your originial id can be found in multiple places
1. i believe its on the label under your battery
2. if the label is unreadable if you registered your phone with samsung website log in you can see your IMEI.

The IMEI and Android ID are NOT the same thing. They are not related in any way at all.
If you mess up your IMEI there is no way to recover it or change it without a hardware device. The IMEI ties your phone to the carrier network and is used in conjunction with your SIM card.
This discussion is about the Android ID - it has nothing to do with cell phone networks or carriers, but it is used by games and the Market to identify your device. It can be changed very easily.

not sure what your referring to as hardware device. Mine was messed up after flashing one of the i9000 roms as was my product code. Many of the custom roms assign a generic imei when installed but is usually restore to original when one click odin back to stock. In one instance doing such wouldn't restore it.
Both were able to be restored using root manager and a hex editor to correct the nv_data.bin file.
Where do you find the device id anyway?

I downloaded an app called "ID" made by "Sora Takayama" from the market. That lists your SIM Serial, Device ID, Android ID and Subscriber ID.

Actually if you look at the first post the user asked specifically about their DEVICE ID (+ the thread title is regarding DEVICE ID) which is the IMEI as i understand. The Android ID is in fact different than the IMEI (DEVICE ID) and its possible he meant to reference android id but i was simply responding to the question as it was stated rather than reading anything into it.
So to be clear my understanding is
IMEI = DEVICE ID
IMEI does not = ANDROID ID
DEVICE ID does not = ANDROID ID
-------------
and +1 on the ID app...i am going to snap a screen shot of it to keep saved on external and hard drive so i have the info accessible if something gets messed up.
Sorry I meant Android ID
What happens if you ddn't write down your device ID when you got your phone?

(I accidentally posted this in an unrelated discussion so sorry if it appears twice!)
Alright, so, last weekend I got a new Samsung Galaxy J7 (SM-J700M) with Android 6.0.1. The first thing I did was rooting it. It was all going fine until I accidentally unticked the "OEM Unlock" option on Developer Mode, so when I rebooted it, it had an FRP Lock.
I used a Latin American firmware to be able to boot it again. At boot, there was this "entel" logo, and this seemed to have changed my IMEI because my phone always said Network Unavailable. I didn't check the IMEI prior to rooting it, but I noticed the printed one and the one shown on the phone weren't the same... but this isn't the real problem.
Originally, the phone was unlocked (no specific carrier/operator holding it), and I somehow "fixed" the Network Unavailable thing by erasing the efs folder on root... well, it was a longer process than just deleting it, I backed up the folder and copied some files (some might know what I'm talking about). After that, the IMEI was the same than the printed one, but, my phone is now network SIM locked!
I have to input a code to unlock it. I did some googling and apparently only the carrier can give it to you, so I tried 3 different carrier SIM cards to see if any of them were the carrier's, but none of them worked as accepted,and I don't know what carrier could it be... I'm even worried it may be a Latin American one (from Chile or Argentina maybe since that's where the firmware used was from) and I won't be able to get it.
I know there are websites to get a code, but I don't want to pay so much and risk getting scammed.
I tried to see if "entel" was a carrier to unlock it, but it didn't help.
Also, when I try to choose a network on Mobile Networks settings, the only available one is AT&T (which I don't use/have a SIM of), but when I accessed their website to unlock, it said my IMEI wasn't registered as theirs apparently.
Then, I also tried using Samsung's Smart Switch application on PC with the Device Initialization option, but when I try to use the firmware from that I get a SW REV. Check Fail.
I might be wrong, but I feel that since messing with the system files/root was what changed it, maybe I can fix it the same way with no unlock code or carrier help.
So, does anyone have advice, or know some other way to reset it? Or do I really have to go get it fixed/unlocked somewhere?
or is it equally secure to use the same sim card but a new different number.
On the same carrier

In general...
Carriers tie the Phone Number with the SIM card Number and the SIM Card Number is tied to a devices IMEI (aka Serial Number).
So if you have a phone number for a device, and then change the SIM Card, the device will not be able to use that phone number on a different SIM.
The only way to tie the phone number to a different SIM is for the carrier to port the phone number over to the new SIM.
This cannot be modified or bypassed on the device because their all tied in to the carriers system for the towers.
I hope that I had explained this okay via text...
Good Luck!

Thank you. I was trying to figure out the following scenario.
Let's say I suspect some kind of remote tampering or location tracking without physical access to my phone.
Which one is more secure:
1. Change the phone number with the same carrier
2. Change the phone number and ask for a new sim card on the same carrier.
This is a European carrier.

There's one thing that you need to know: tracking your device is also possible when the IMEI number is known(and the IMEI can be changed also) so even when you switch the sim card and the device has location services or internet access it's quite easy to locate your device once it's been setup.
Actually one of these people has all the info from the phone box (IMEI, etc)
Are there other ways to track. Is it easy for anyone to track me with an app, etc. Is it equally easy to track an older non-smart phone.
I saw several time, errors with I think triangle with exclamation mark (I can't remember the exact words) that I have no access to network. This would stay briefly and then be removed. What are the implications of this.
If someone has my number, is it fairly easy for them to get the IMEI.
If they have the IMEI, does this allow them to track location or also get access to my data.
How can I protect myself.

How would these 2 situations be explained.
I am putting the regular (not smart) phone in the pocket. It turns on. It appears I called my own number. It's possible that I pressed dial but I felt I wasn't pressing any keys. It's an old phone with a square large button below the screen. The call log on the phone does show that a call was made to the same phone (calling my own number). would this be visible on the phone if it was done remotely (or would that even be possible: remotely causing a phone to call itself)
I am told by an older guy that someone called from my number and gave a different name than mine (I am asked if I use a different name). The phone was in my possession at all times and it's a smart phone.
I was testing google find my device. I am getting "can't reach device" with location ON on phone. Why would this happen?
On the other hand, I can "play a sound"

Hi, yeah seems like your device is high jacked by someone. There was a case like yours some month ago here on xda(don't remember the thread right now). You should wipe your device completely(within twrp format every partition.
Then install a aosp based rom.
Maybe this wipes the remote access too, but sadly I'm not sure cause the other guy did it he same but after this it was like before.
Which part makes you think it's hijacked?
not being able to find the device.? or something else (someone calling with the same number in the above post)
It did find the device after I moved it a little bit. It wasn't finding it when it was still.
Then it was not finding the device after I turned off location.
Is that how it works if someone is searching by using IMEI with an app. ie. if I turn off location then device cannot be located.
Which AOSP ROM?
In that case, if remote access wasn't wiped, what was the reason?
If someone has the IMEI, can they hijack repeatedly?

You should try. It's also possible to track you again if he has a duplicate sim(yeah, that's possible). But I don't think so.

There was no solution sadly :crying:
If a phone is hijacked, does that mean the attacker has access to all data, camera, mic, calls, etc. Can make calls from the number, etc. or just track location.
Would this be visible to the phone company?
Is there a solution.

With Trojans its all possible.
Did you already do what I wrote? Format the phone completely and install a aosp based rom? You didn't wrote what rom you're running and which apps... Maybe you have a app that's faulty

Further to previous comments By strongest
Yes, if hijacked (trojan installed ) then it's likely they can access anything they want, though it depends on Trojan installed.
As you got a phone call from someone who gave a different name your phone may have been cloned (possibly after malware infection or if someone has hadphysical access to it & copied imie etc). This is good in that your phone bill will show activity of the other phone & you can get help from your phone company. Your Google acc may show something too....
have you done the basics? Installed good anti virus, checked if rooted, checked if app showing in device administrators etc. Even if it comes back negative a port may have been opened & Trojan self deleted. Then you need to either try a firewall or check network traffic to identify unknown connections so probably easiest to just reflash full stock ROM or custom ( best as LineageOS will give you security updates every month ) ( make sure you backup your pic, files, contacts etc first )
They can only track your imei if they have access to the network infrastructure (as far as I know) assuming you have removed any Trojans, tracker, spy app etc and have clean install a ROM,
If you had a Trojan you should assume they have ALL your passwords, including your WiFi (maybe router admin too!) Change them all (use a password manager)
