How to Upgrade your Infinix Hot Note X551 to Android 5.1 Lollipop

I wrote the other post in a rush. Then promised to write this one in a few minutes time, but failed to do so. I know some of you are so pissed right now. I’m sorry. Here we are now.

If you want Lollipop on your Infinix X551 Hot Note you need the following:

• An Infinix Phone with enough battery
• A USB cable. A proper one.
• A computer with VCOM Mediatek Drivers properly installed
• SP Flashtool, a Windows Program
• The ROM to be flashed. (I know it is supposed to be an update).
• Patience, it won’t take time.

First things first.
Read the whole post below before you start doing anything. Read and understand. Do not rush. This post is detailed and there are external links to more detailed explanations that will help you set up your computer. Read them too until you are sure of everything.
With this post anyone can upgrade their phone to Lollipop. I have made it very easy.

Note: Any damages to your phone are as a result of your own errors. I am not to be blamed. 

• Download the ROM

I could have uploaded the ROM to my Google Drive and given all of you an easy time downloading it, but I have a very slow connection and uploading it might take years. If you know someone who has downloaded the ROM already it will be easier for you.
If you don’t, then buy yourself some data (Ksh. 500 gives you 1GB on Safaricom, Ksh. 699 gives you 5GB on Airtel) and get ready to download.
If you are planning to download it to your phone, first of all go to Google Play Store and download an App called Mega. Sign up for an account and log in thereafter. Then visit this link: Download Update Directly. You’ll then either make it available offline or transfer it to your cloud drive so as to download later.
Send it to your computer, if you downloaded via phone. Extract it to your desktop.

• Set-up your Computer

This could be the hard part.
Download SP Flashtool here: http://androidxda.com/smart-phone-flash-tool. After downloading it, extract it to your desktop then launch a .exe file inside called “flash_tool.exe”
Download VCOM tools from this link: how to install mediatek sub vcom driver for windows. You’ll need to read everything on this previous link as it has a guide on how to:

1. First disable Driver Signature enforcement on Windows 8,8.1 and 10.
2. Then install the necessary drivers.
3. This is very important. Nothing will work without setting this process up properly.

After setting up the VCOM tools, you need to launch the flash tool and then:

• Click on Scatter Loading
• Look for a text file from the ROM you had downloaded called “MT6592_Android_scatter.txt”
• Wait for the SP Flash tool to compile its own stuff.
• Select Firmware Upgrade option

You can see the images below to know where “Scatter Loading” and “Firmware Upgrade” can be found.

• Phone set-up

Before continuing, you need to go to your device. Go to settings –> Developer Options –> Enable USB debugging. If you don’t see Developer Options, go to About Phone and click on Build Number until it says “You’re now a developer”.

• Then Enable Debugging
• Remove your phone SD card.
• Switch it off.
• Pray everything works.

• Actual Flashing

After switching off the phone. Go back to your computer.
You are on the SP Flashtool Window. Click on the Download button.
Now connect your phone with the computer through the USB cable. Wait for the magic.

You will only be done when you see a big White Tick on a Greenish-Yellow background. Otherwise don’t remove/disconnect phone.

• Reboot

It will take quite some time to reboot. Be patient. When it boots, you will meet a whole new experience:

Make sure to directly go to Settings –> About Phone –> System Update and Download and Install the Updates available.
I haven’t encountered any issues with the three devices I have flashed and so I have no answers if you have issues.
Please note that I am not liable to any damages you may encounter.

Tell me how it goes. All the best.
