1. Be Sure your phone (Hot Note) is Still On and very well charged. Also "Unroot your phone" if it's rooted, you can easily unroot with King Root App.

2. Go to where you Extracted your SP Flash Tool v5.1352.01, inside it, you'll find the file name flash_tool.exe , right click and Run it as Administrator.

For the first time, it will bring a Window saying - The Scatter file cannot found, please make sure the file is exist before download.

Just ignore that by clicking OK.

3. Click SCATTER LOADING, this opens your folder. Navigate into the folder where you had extracted the Lollipop ROM file for Infinix Hot Note X551.

According to my screenshot, I saved my Rom in my Desktop.

Select the scatter file with name - MT6592_Android_scatter.txt

Wait till it completely loads up on the flash programs.

4. On the SP Flas-htool, where you see Download only, click and change it to FIRMWARE UPGRADE

5. This is the tricky part, you'll pass if you follow carefully.

>> Pick up the phone, it should be still ON at this stage >> Now plug the USB

On your Flash-tool, Click DOWNLOAD icon, wait for some seconds... no worries, nothing happens here.

While it is still plugged in, Now Power OFF your Hot Note Device. 

Seconds later, some readings will display on the SP flash tool.

6. Give it some time, Do NOT interrupt the process (well, unless you want to brick your device) 

7. When the Process is Complete and successful, You'll get a Green Check Mark saying Download OK in the Flash-tool on your PC, now you can unplug your phone.

Power ON the device, Keep calm as this will take a while since it's the first time.

When it's finally On, Follow the Instructions on the Welcome message and we're done!
