Hello.

Before to write IMEI Certificate, do the next:

1. Make Factory data reset and wipe cache partition.
2. Root the phone.
3. Make Wipe Security.

CDMA_RASHID · 12-19-2014, 09:42

phone already rooted and wiped factory data.....

There's no security wipe option for SM-N900.

Still fail to write Cert after factory reset and root....

Those three are always different in all Android Samsung phones....

Dont know why but thats the way it is ...... hope it answers your query....

Octopus box · 12-19-2014, 10:27

Try to write different firmwares to repair baseband. When baseband will be repaired, try to write Certificate again. Also try to write one of the Services IMEIs from the Software list. Post here full Software log.

CDMA_RASHID · 12-19-2014, 10:33

Thanks for ur response brother....

I am able to repair Unknown baseband by Deleting the Efs folder from root ....

And yes im able to write different cert and super Imei .....

But why am i not able to write the backup Cert ?

any thing wrong in backup procedure ?

Octopus box · 12-19-2014, 10:35

No, this is because EFS and Security are damaged in your device, so the phone doesn't accept writing data. If You have the first original security backup, please write it into the phone and then write Certificate.

CDMA_RASHID · 12-19-2014, 10:38

yes i do have backup Sec....

but same thing happens unknown baseband after writing sec file

Octopus box · 12-19-2014, 10:40

Repair baseband and write Security backup (it should be from your device, not from another SM-N900!), and post here the log.
