Here is what I have discovered so far.
!!Please don't mess with any of this unless you know what you are doing AND you can take it back to t-mobile if the buttons stop working. !!
This phone is going to be a real challenge. None of the unlock stuff works.
If you type *#7465625# into the dialer it FC
If you put in another SIM it says no SIM and never asks for an unlock code (on my first one the front buttons even stopped working)
There are no files big enough in /efs/ to be the nv_data.bin that we all know and love
The /tombstone folder show some promise but I am not sure if you can edit any of those modem images.
Has anyone had one of these apart? Do we know what modem chip they have? The Europe S2 at least had an nv_data.bin file.
Let me know what you guys have seen. Any of the ROM devs have the *#7465625# screen working or the unlock popup when you put in another SIM?
I appreciate any input on this. Sorry that I have hit such a wall on this one

correction, if you put in a non Tmo SIM card it will pop up the same screen found on other SGS1/2 asking for the SIM unlock PIN
mine is unlocked already over the web, let me know if you want me to look up something, as i now have my own unlock code to compare against
running *#7465625# it tries to load "personalization"
then it FC and shows
Sorry!
the process com.android.phone has stopped unexpectedly. Please try again

i can continue doing stuff normally in the phone after pressing "OK" to dismiss the message
Yup i inserted a Rogers SIM in mine and it asked for unlock code

I was on rooted stock when I got an unlock code over the web from TMo. Don't know if that made a difference.

stock Tmo ROM (i bough the Tmo version of the T989)
no root
the first thing i did after i unboxed the phone was to plug in my WIND SIM card to see if it was unlocked or not, but immediately got that POP up asking for the PIN
WOW.... maybe they just block ATT sims :'(
I found an older ATT sim and managed to unlock my phone but I couldn't find any differences in any of the files I backed up. It must interface directly with the modem somehow. Maybe there is a /dev/ device that has the modem configuration but is only mounted when you use the unlock code. Anyone have any information on that?
I have an SGS2 that has been affected by the corrupt efs problem (Unknown Baseband/IMEI and no sim/service). Usually restoring the backups of the nv_data files automatically generated by the phone would solve this problem but since we dont have these files I'm kinda SOL for the time being.. Any ideas??
Sorry if this is slightly off topic, but the nv_data files are directly related to previous methods of unlocking this phone, and if anyone has any idea where the equivalent files are I'm guessing they would be in this thread.

No that's fine. You are right in that if we could find the nv_data files we would be 50% of the way there. Did you flash a modem from the Europe SGS2? They are very different.
Last night I started running through 1 partition at a time like this.
Code:
cat /dev/mmcblk0p1 | grep ssnv
I am looking for a partition that might have an nv_data like file in it. The next thing I was going to do tonight is look for my unlock code in each partition. Please let me know if anyone has any ideas or a list of what all 28 partitions are.
The baseband/efs files are located in these two emmc partitions
/dev/block/mmcblk0p13 mounted to /system/etc/firmware/misc
and
/dev/block/mmcblk0p17 mounted to /system/etc/firmware/misc_mdm
with out the device mounting those points correctly, or with them being damaged you will no longer have your baseband or sim detected.

did you effectively check these files before and after an unlock? a md5sum and a binary compare.
i could be they have went the same way as htc where the nvm is on a separate mount that the radio only has access too.

I will check again... I backed up those folders before I unlocked it.
I hope they didn't lock down the NV Data :'(
Same here when i input *#7465625# FC maybe in the next update nspro or z3x will release something..

ditto here. got the unlocked code from TMO. insert a non TMO sim and it asked for the code. it was successfully unlocked, but when I typed in *#7465625# it FC. I'm on Juggernaut 3.1
I still haven't found any binary diff in any files I have. There must be a mount point that we cannot see. If anyone unlocks their phone maybe a logcat would help.
It's interesting when I type that code.. I'll lose signal and it will come back (AT&T).
This method has been sent to me by android235, I can not personally attest that it is working so please if you do that, make sure you have a backup or odin to reinstall your phone
After root, use a file explorer.
I use the ES File Explorer downloaded from the market:
- Launch it
- Goto "Settings> File Settings". Be sure that Show hidden files is checked
- Also be sure is checked "Settings > Root Explorer"
- In "Settings > Home directory" write "/" (without the quotes)
explore the "efs" folder in the root
- move the following files in a backup folder somewhere to your internal SD card (you will need them if you want to restore later to original phone setup) : .nv_core.bak, .nv_core.bak.md5, .nv_data.bak, .nv_data.bak.md5, nv_data.bin, nv_data.bin.md5. Moving them they will be deleted from the efs folder (that's ok).
Reboot.
Now you will have it unlocked but with the generic IMEI.
Peace out.

Any way to restore the IMEI afterwards? Or is the simlock check based on the IMEI?

I suppose the files you saved are to restore if needed, for the rest I don't know as like I said did NOT try myself
Nah. I meant whether it is possible to restore IMEI while still having unlock. If I restore the files, the lock should be back. (My glide is unlocked, but thats not the point)
Sent from my SAMSUNG-SGH-I927R using XDA
I'd rather spend 25$ for an unlock key on Americanunlocker.com
(worked great for me)
In fact, I have tried to hack the nv_data.bin but seems that it is not the same as galaxy SII and galaxy S.
Although you will get unlocked (generic IMEI) when removed those files,
I highly recommand that you have to backup them in a very safe place. Otherwise if you encounter any problems, you have to sent back to AT&T / Rogers.

The method will work.. i had tested it earlier.. a generic imei will be assigned..
however some operators do not accept generic IMEI..

This method is perfect ! My phone accept the Free Mobile's SIM card and is recognized by Orange and Free Mobile's networks.
(It connects too on the two another french carriers when theses networks are too low, I don't know why and if the reason is the AT&T ROM or the unlock method. By the way, although I am connected I can't do anything.)
i don't like having a genric IMEI. will wait for anther method or just pay for an unlock key (when i get my device ofcurse )
What do you mean by generic IMEI? Is it all 0s? Does this mean that it will no longer be detected as a smartphone?
I just tried this method and it did work for me thank u
one Q is there any way to fix genric IMEI and keep unlock .
Edit: I restore my files from a back up and relock the phone ..went to ebay bought unlock code for about 8 dollars ..Done

I've done the same thing with another website -more expensive x-( (Fastgsm.com), although it worked.
The only problem though is that every now and then the phone asks me again for the network unlock code. This has forced me to carry a text message with the info on the phone. So far it has asked me 3 times the unlock code. Every time I input the same code received, every time it accepts it and gets unlocked. But I think this is strange, this is the first phone I had that this happens.

I'm very interested in this thread since i'm french, and about to buy a phone in the US to use it here, in France.
If i understand well, the trick for unlocking it by file deletion is a bad idea since generic IMEI are not too well accepted on french networks, and when you buy an unlock code, it keeps prompting you sometimes.
My other option is the myTouch 4G Slide, so i'd probably better go for it

Hi folks,
strange issue, I bought the HTC One X locked to our network, from another guy. It was rooted via HTC dev with Mike's revolution over it. Everything was ok, except it was locked to a network I dont want to use with.
So I tried with HTCSimUnlock.com, purchased unlock code, received it instantly, and tried several times to insert it. But every time, display showed "unknown password" and no luck.
What I discovered when I took to record the procedure of unsuccessful inserting the code to claim for money back, was that imei number is missing, and actually in the settings imei showe as "unknown". The most interesting thing is that phone is working normally, with of course, sim card from the network that the phone is locked to.
I wrote to HTCSimUnlock.com ,and waiting for the answer, but I dont know should I do something, try to get the RUU back to stock rom, or hard reset, but am little afraid that phone could stop working...

you could try the hard reset or RUU. whether the phone will stop working or not, i personally would try it, but you make your own choice. its a risk best thing i can suggest is play it safe, sell it on and get an unbranded one
How could you buy a unlock code without IMEI in the first place? And secondly, if you reboot into bootloader and choose "show barcode" then I guess there is a IMEI? In that case, just try a new rom, or better yet a ruu.
Download the appropriate Ruu and update it, this is a common issue on the S2 as well with ics during flashing, possibly someone updated it before you and it didnt go according to plan.
first time i have come across IMEI known, i know the serial number came back unkown once, try the RUU, like i said i dont think it will mess up your phone because your restoring it to factory conditions obviously.

good afternoon friends, I come to you for some doubts that I have about the update of my team .... I have a moto z play with android 6.0.1 I want to update for compatibility issues in applications, but I have activated the good dual sim so I bought it second-hand, can I update directly to 7.1.1? and from there go up to 8 by means of adb sideload? and what is the procedure since I read that you need to omit the lines of the modem and the sfg to not have problems with the imei ..... someone could help me please? and excuse me but occupy the translator to create the theme.
Can we see a screenshot of your Settings>about phone screen please, showing your device and build number? This should help us figure what device you have and what builds to flash.
Provided you flash the correct firmware for your device, your IMEI should be okay.

Thanks, if you're updating, usually it's a good idea to full flash, including modem and fsg. Else you'll have issues with OTA updates.
Normally flashing stock firmware shouldn't cause problems with your IMEI, but without knowing the history of your device, it's difficult to say. If you want to, could you provide your device's get var info?
A) assuming you have ADB and the Motorola drivers set up on your computer, boot your device into the bootloader. Connect your device to your computer via USB.
B) open an ADB terminal and in the terminal type 'fastboot devices' without quotes. Press enter, that should return your device's serial.
C) if you get a response, type 'fastboot getvar all' without quotes in the ADB terminal. Press enter to display a output of your device's parameters.
D) copy paste that output here or upload it somewhere. You may wish to omit your IMEI from the output. That output should tell us if the device was previously unlocked or flashed with a newer firmware.

ok I understand, I explain the equipment I acquired it from use and has a blockage for non-payment in ATTMX that is why they activated the second sim, I do not have backup of the efs and the recovery does not let me, my idea is to go up to 7.1.1 and then go to Oreo by means of adb and already being there to activate the dual sim again and be able to continue using it ... so I ask you if I can skip those commands to avoid taking risks with the imei

Again, if you're updating with the correct firmware and the device had not been flashed with custom ROMs or had downgraded firmware in the past, I do not think you will lose your IMEI. I would recommend you use those commands.
However, if your device was blocked for non payment, are you sure you can even use dual Sims? I'm concerned the previous owner's network provider may have black listed IMEI 1, so even if you update to Oreo, you may only have one active SIM. I'm also hoping that device is from non payment and not stolen...

I suppose they stopped paying, and if right now the dual SIM is activated in the first line which is the original IMEI does not signal, but in the second that is the IMEI 0 if I can use my line but the same way only works for ATTMX, that's why I want to think that updating to 7.1.1 and later to oreo can activate the dual sim back and that it works again like now .....

Even if the device says it's dual SIM, the IMEI for one of the SIM slots is likely blocked not by ATTMX but for other providers too (hence the blacklist). I doubt if you update whether you will get dual SIM usage, as your IMEI stays the same usually, so even if you're updated to Oreo, you may still have only one SIM active. The network may just keep rejecting that IMEI number.
I'd honestly think about returning it unless you're happy with just single SIM access.

does not look, I mean the original equipment is a sim which is blocked for lack of payment, they activated the second sim and obviously that is 0 which if I line with ATTMX and good until now I have no problem it works for me and apart I bought it cheap, the only thing I want is to update to be up to date and so already updated to activate the second sim

Yup, so if I've understood you correctly
SIM 1) Blacklisted IMEI due to non-payment by the original owner . Likely will not work even if you update.
SIM 2) I don't think this IMEI 2 gets blacklisted automatically, IMEI 1 is usually the one that is blocked, unless the original owner or ATTMX asked for IMEI 2 to be blocked too.
However, I still think if you update to Oreo, you will not be able to activate the dual SIMs. IMEI 1 will still remain blocked. From what I understand, only the original owner/ATTMX can reverse the block, and as it's due to non-payment, you'd likely have to ask the original owner to clear their debt with ATTMX to clear the block. The block exists on the carrier level, so unless you can change the IMEI (which is something indiscussable on XDA), you are stuck with one SIM, despite having a dual SIM model.

if the original IMEI 1 is the one that is blacklisted by the operator, the IMEI 2, which is the one that was activated and is 0, is the one that gives me line, so I wanted to suppose that if I update and when I am in Oreo I could activate it again with the tutorial that goes on the web and thus continue to occupy the IMEI 2 with the line I have ..... now I hope to explain myself .. I doubt very much that the owner pays since we are not in contact.

So you'd likely have only IMEI 2/SIM 2 active, especially if the original owner has not cleared the balance. I do not know of tutorials that could help you restore IMEI 1 (and they are likely not permitted on XDA). I wish you luck in this endeavour to get your dual SIM device working fully.

If the baseband version/ids/content in *#0011# isn't there, try
restarting the device?
changing firmware, preferably with a newer modem?
wiping data?
For installing firmware, there's odin. Use odin, the stock rom (official firmware), and samsung drivers, Insert the usb cable, switch off the device, hold power+volumedown+home(the button on the middle), grant its permission, select the stock rom in odin, start. New firmware might require odin 3.13.1. The error "failed: device _ binary _" means that the firmware is old, somewhere in the middle of the firmware version code is for example U5 or S5, if U6 or S6 is already on the device it won't install u5/s5.
To check if the device is blacklisted, the code is *#9900# > run cp based log > copy to sdcard. Select nothing else. It is available in the folder /sdcard/log/err/ , sdcard meaning internal storage or device storage or internal memory. Open LitmusLog....txt and scroll down, look for the part that says reject info list, look for Cause:6 (basically this device can't be used); Cause:3 (basically this device can't be used with this sim). It is also available in /sdcard/log/err/ss_log/*/cp_members.txt , but the reject cause is in hexadecimal, and resets after a reboot, compared to the other file that keeps reject causes until it's replaced or cleared in another menu. For more info contact your mobile network operator.

Sadly this not helped, the imei is blacklisted, and modem update not fixed it for me. :/ I contacted the network operator and because I'm not in contact with the person who sold me the phone, they can't tell me anything, because I don't have the rights. So I think the only way is the imei changing method, but I don't know if it's even possible or how.
Sorry if my English is bad, and thank you.

I did a bit of research....
- it is illegal to change imei- if hat means anything to you, lol
- it is against Ebay's policy to sell phones with bad imei
- there is an xposed module to change imei but you would trip knox

I think in my country it's not illegal, but not quite sure.. And i didn't know this, the guy wrote it down in the ebay ad even, so it went through.
Thank you, I will look into it, but I think I will sell the phone as a 'working display part'.. Motherboards are not cheap.

It's perfectly normal except you can't use a sim card? Or is there more things wrong when imei is blocked?

It's perfectly normal, everything works, except if I insert a sim, it will show a notification: ' can't connect to network '

Hello, I bought a used a5 2017 phone from ebay and when I received it, my sim not worked, then my brother's sim either. I think the imei is being blacklisted. Is there any way to change it, or how?

Imei is locked to the device as far as I know. This is why a device can be blocked after being reported as stolen. If it is imei blocked then you should get a refund or make sure Ebay is involved if the seller refuses to.
