sn write tool – Get your IMEI number ready

Since we are going to write back your IMEI number back into your phone, obviously you need your IMEI number. Where can you get your IMEI number? If you have access to playstore in your phone, there are various IMEI reader apps. Install one of these IMEI reader apps and write down without mistake your IMEI number on a piece of paper. If you do not have access playstore, you can also find IMEI number on the back of your phone, or below your battery of your phone. Still did not find it? One last chance.. get the box that your phone came in. Usualy these phone boxes can have IMEI information on them too. When you have got your IMEI number, we can proceed.

Prepare working folder for Sn Write Tool

Since we need to download some files, it will be good if we have a working folder on the desktop. As such, create a folder called IMEI on your system desktop. Within this folder, create three other folders called, DRIVERS, VCOM, ROM and Sn_write_tool. With working folders all set, let;s download needed software for our task.

Download these software or files

We will need the original ROM file for this task. Visit your phone manufacturer to down load and extract the ROM file into the ROM folder that you created in the above step. In my case, I am using Infinix phone, as such, either i can download from the official site or download the official rom from this site.

Now that we have downloaded and extracted the ROM, you need to download your phone’s USB drivers. Download these files into the DRIVERS folder you have created earlier.

With phone’s USB drivers downloaded, now we need to download VCOM drivers. VCOM drivers are legacy shitty drivers that we need to use. In my case, I downloaded my vcom drivers from this site or from this site. Save and extract the files into the VCOM folder you have created.

Now we need the most important file, the SN Write Tool itself. You can download the latest sn write tool from here. In my case, i am using Sn write tool version v5.1904. Extract the sn write tool files into the Sn_write_tool folder that you created earlier on your desktop.

Install The Downloaded USB Driver And VCOM files
