Hi guys,

So, we're currently working on a way that hopefully allows us to switch the IMEI # of an unrooted snapdragon Note 7 with that of another Note 7.

We've tested:

- Successfully extracting backup file from phone and locating / changing IMEI
- Swapping out with a random IMEI # (69 69 69 69 69 69 69) which successfully changed, however, cut service off to the phone.

Currently I'm told we need to swap them out with other Note 7 IMEI's or it wont work (as the random one we used just disabled service). There was a potential issue with my using Miguelina's backup file to restore Melissa's phone. So, although it came from the same carrier there was an EISN mismatch which couldve been why Melissas phone cut off service, as it didnt match her EISN which was seeing Miguelina's when it came back on. (thinking outloud)

Also, pre-paid carriers really have no way of attaching your devices IMEI # to your ID or their service. Could look into work-arounds with this on the side too. Right now, focusing on trying to do this. Provided everyone doesn't get scared and go swap their devices- we'll work as best as we can to see if this works.

No promises, but we're trying.

Thank you for your tireless efforts!!

Some hints from my side:

1) Do not use random numbers for IMEI, e.g. 69696969696969 does not fit the IMEI pattern. (Check/verify with http://www.imei.info/ online).

2) Creating valid (non-n7 specific) IMEI: Use http://www.imei.info/calc online (be aware of the 'check digit')

To create a valid n7 IMEI, simply use the TAC code ( = first eight numbers of any real n7 IMEI) and fill the rest of the new IMEI with random numbers - with correct check digit!

Thanks for your effort!

Really it can be generated using the first 8 of our own?! Are you sure? That would make life a lot easier!

Yes, just verified it again. Will post a small image with further explanations to the fb page now - as i can not attach images here.

That's fucking awesome. You can use imgur website too.

Thank you for this info, I'll look into this as well.

You guys need me to work on a step by step tutorial?

Not yet. I must sleep. Can test that method tomorrow. If you're awake before I am, try working on your phone connection to that software we tested.

Eye-eye Captain!

Just in case the IMEI calculator goes down (Samsung will definitely not like it ), I save the check digit calculation for reference if needed sometimes in the future. With that we do not have to rely on any tools to get a valid n7 IMEI.
For reference only:[spoiler]The last number of the IMEI is a check digit. The Check Digit is calculated according to Luhn formula. The Check Digit is a function of all other digits in the IMEI. The purpose of the Check Digit is to help guard against the possibility of incorrect entries to the CEIR and EIR equipment.
The check digit is validated in three steps:
Starting from the right, double a digit every two digits (e.g., 5 → 10).
Sum the digits (e.g., 10 → 1+0).
Check if the sum is divisible by 10.
Conversely, one can calculate the IMEI by choosing the check digit that would give a sum divisible by 10.
For example:
IMEI: 35145120840121
(5x2, 4x2, 1x2, 0x2, 4x2, 1x2, 1x2) = (10, 8, 2, 0, 8, 2, 2)
(1+0+8+2+0+8+2+2) + (3+1+5+2+8+0+2 ) = 44
Luhn Digit : 6
IMEI: 351451-20-840121-6

Hopefully @aztek will dream about a solution for non-rooted n7 devices

@catwoman: If you like you could try to put something together for the first part (IMEI generation) with the image I posted below and these basic steps:

1) Get the first 8 digits of your original IMEI (eg. by dialing *#06#). This is the "TAC" code (Type Approval Code) for your specific n7 model.
2) Use online IMEI calculator http://www.imei.info/calc , start with your own 8 digit TAC code - followed by 6 random numbers of your choice (I use my birthday ). The last number is the "check digit" and is created by the calculator for you.

TAC (8) + Random (6) + check digit (1) = valid IMEI (15)

done

Thank You!

So by doing this, it will mask your note 7 as a different device? When I put the first 8 of my IMEI, my 6 digit birthday, and the Auto generated digit it said the device IMEI was a Note 2. Will this affect my service or any functionality of my device if I add this IMEI to my device?

Please please please boo, watermark the hell out of your tutorials and screenshots lol
