Note 3 IMEI writing questions

The AKSEEDNO I doubt anyone can really help you out with. I assume most if not all of the box companies have some kind of algo calculator built inside of them where it calculates the AKSEEDNO, but I haven't seen any public documentation on any tools or methods to calculate it.

One work-around is to use a box (I'd prefer to use the SPT box in this case) to send the calculated AKSEEDNO. You perform the IMEI repair operation with the box, and untick reset/restart phone. You need the phone to still be ON after the IMEI repair. After repairing with the box the cert will fail. It's at this point you use the terminal to repair the CERT. You won't get MSL auth error or AKSEEDNO error because the box has already sent it. IF you restart the phone between the IMEI repair and the CERT repair it'll forget the box sent the MSL and AKSEEDNO and you'll be back at step 1.

Ok, Im doing that you told me, but when im trying to insert certs, I am getting:
+IMEISIGN:2,

OK

but cert still fail, If i run AT+IMEISIGN get N/A

Do you think my certs are not good?

I think you are running the commands incorrectly. First you need to clear imei cert by:
AT+IMEISIGN=1,2,0
then you need the certs, which are 5 different AT+IMEISIGN=2,1,[certs]
then you need to close cert writing:
AT+IMEISIGN=2,1,FF
and finally you need phone to verify certs:
AT+IMEISIGN=0,1,0
and each commands must respond with OK.

I got it working , thank you man.
I noticed that i have to repeat the command twice to get it work.

My last question is if we need 5 certs why some certs file have 3 certs only. Can we try just with 3 certs?

hi i have 2 s5 g900t

It's really interesting. Hi dest, how can I find Certs.

then you need the certs, which are 5 different AT+IMEISIGN=2,1,[certs]

^^^You can either buy trade or pull logs to get certs...but that's it..unless u are one of the very few people that have possession of Samsung private key used to calculate imei certification ...the reason why pulling from a Exynos processor and writing to a Qualcomm doesn't work is because Exynos has 3 imei certs and Qualcomm uses 5...

Hi there, this is my research experience with SM G900m:

1.- I was able to force another tool calculate ackseed for me on the fly. Using mitm atack.
2.- I was able to force same tool send any IMEI and Sing it for me.
3.- I was able to make baseband mistake calculating Imei check digit (15th), and preserve the IMEI CERT: PASS.
4.- Unfortunatelly Carriers on my country use the first 14 digits to validate phone on its network.

Conclusion, Certs are the problem to repair to any imei.

I thing we have the same tools right now for imei repair. We just need a way to dump the Certs of phones that are blacklisted on one country and use it outside. So we can interchage certs and create a database to avoid clonning the imeis in the same country.

Do I miss something ? I had under my hands one note 3 demo unit,
and when I opened it, I saw it's missing most of radio parts
(baseband chip was there, but PFO's, switch, filters, antenna connector - missing on board)
Are you saying that your test/demo units have mentioned radio parts ?

if so, writing imei / certs will defintaly make them work ...
