How to use SN Writer (SN Write Tool)


  1. Unpack the SN Write tool zip file into a folder and run SN Writer as Administrator

  5. The System Config dashboard should pop up

  6. If you wish to write IMEI to the phone then tick IMEI under Write Option. Under IMEI Option, tick the appropriate option (mostly Dual IMEI) depending on the number of SIM card slots the phone has. For the rest like Bluetooth Address, Wi-Fi, Address etc, ticking the box in front of them is just enough

  7. Click the MD1_DB button at the bottom. In the Window that pops up, navigate to the location of the MD1_DB file (usually named like BPLGUInfoCustomAppSrcP_MT65**.....), select it then click Open

  8. Click the AP_DB button at the bottom. In the Window that pops up, navigate to the location of the AP_DB file (usually named like APDB_MT65**.....), select it then click Open

  10. You should be back to the SN Write tool Home screen, click Start

  11. If you're writing IMEI, enter IMEI 1 and 2 then click OK

    [Image: how-to-use-SN-writer-11.jpg]

  12. If you're writing Bluetooth Address and it is something like bc:b3:08:4c:1f:99 then you simply type bcb3084c1f99 then click OK

    [Image: how-to-use-SN-writer-11b.jpg]

  13. If you're writing Wi-Fi Address and it is something like bc:b3:08:cb:c0:f6 then you simply type bcb308cbc0f6 then click OK

    [Image: how-to-use-SN-writer-11c.jpg]

  14. SN Writer should now display Start searching preloader com port and handshake. At this point, switch off the phone (still with battery inside) and connect it to the PC (do not hold any button on the phone) via a USB cord

    [Image: how-to-use-SN-writer-12.jpg]

  15. You should now see Start searching kernel com port and handshake, just sit back and don't interrupt the process

    [Image: how-to-use-SN-writer-13.jpg]

  16. You'll then see Start switch to MD meta and init Modem database. At this point, the phone will come on. Don't worry, SN Writer is simply booting it into Meta Mode

    [Image: how-to-use-SN-writer-14.jpg]

  17. Next, you'll see Start loop write data to nvram

    [Image: how-to-use-SN-writer-15.jpg]

  18. You should then see Start backup nvram to BinRegion, you're almost done

    [Image: how-to-use-SN-writer-16.jpg]

  19. You should new see a green PASS prompt. You can now disconnect the phone

You can get the file in your phone firmware folder or extract from another phone same model.

BTW, what's your phone model?

.jpg   apdb.jpg (Size: 97.4 KB / Downloads: 5) Hi,

I'm using a Moto M XT1663, recently I formatted and flashed the stock factory image and in the process ended up formatting my nvRAM and losing imei information. I want to restore my old IMEI (the ones that actually came with the phone), I used SN Writer but it won't move beyond "Start searching kernel port and handshake", I tried disconnecting and rebooting the device at this point but it didnt work, also I'm not sure if I am using the correct database files. attached Screenshot of the contents of apdb and modemdb folders, please tell me which files are the correct ones.

If possible please revert me back via email at [email protected], I'd appreciate the help, I am against going back to the service centre due to bad experience with them.


Here is the error I'm receiving
