Flash Infinix Hot Note X551and X507 with Android 5.1 Lollipop

How to Flash Infinix Hot Note X551and X507 with Android 5.1 Lollipop latest official update

On August 2015, Google announced the entry of Android One program in Africa with the launch of the Infinix Hot 2, Android One. Infinix (formally Sagem Wireless) is one of the fastest-growing smartphone brands in Africa and parts of Asia.  The Infinix range of phones are Mediatek (MTK) powered Android smartphones developed for low-cost markets. They have since become a hit with consumers from these markets owing to their relatively decent-almost impeccable specs at a considerably low price. Here in Kenya, the launch of the Infinix Hot Note X551 and X507 series which boast a larger screen estate coupled with more storage capacity and faster processing has seen a wave of increased demand in the uptake of the brand among Kenyan smartphone consumers. The fact that the Infinix Mobility company made a concerted effort to bring latest Android 5.1 Lollipop update to these two mid-range phones is something that has been met with a lot of awe by their  users, attracting even long time Tecno die hard users into the Infinix love circle in a similar manner.  This tutorial will show you how to properly Flash Infinix Hot Note X551and X507 with Android 5.1 Lollipop latest official update.
This Lollipop update brings:
  • XUI upgraded to 1.N.0.6
  • Optimized system stability and performance
  • Enhanced encryption application feature in System manager
  • Added online theme feature in Theme
  • Added delete button on image preview screen in Gallery app
  • Added notification icon on magazine lock screen
  • Optimized screen lighted up slowly issue when incoming call
  • Fixed scheduled power on and off invalid issue by recent app cleaner
Across the web, several  upgrade tutorials exist on how to update your Infinix Hot Note X551 and Infinix Hot Note X507 to Android 5.1 Lollipop but I found most of these to be superficial and difficult to follow especially for first time users looking to flash their Infinix device to Android 5.x Lollipop. Most users encounter problems with proper MTK_VCOM_USB drivers installation, without which a successful upgrade process is near impossible.
This guide, therefore aims at making the upgrade process as simple and easy to follow as possible. Call it a “Noob’s guide to flashing Mediatek (MTK) powered devices!’

Installation Process

STEP 1: VCOM USB Drivers Installation

  • Extract the downloaded VCOM drivers to a folder on your desktop.
Usually drivers installation on a PC is not a problem but installing MTK VCOM drivers is a bit different which explains why many users encounter difficulties while flashing and upgrading their Mediatek powered phones and tablets. This is so because most editions of Windows including X64-bit versions require that all drivers be digitally signed before install installation. It so happens that MTK USB drivers are not signed, therefore, you will need to DISABLE Windows Driver Signature Enforcement to ensure the drivers will install successfully regardless. Do this if you are on Windows 10, Windows 8 or 8.1. The easiest way to Disable driver signature Enforcement is by using elevated command prompt (CMD).
  1. Go to: Start> Run and type CMD Right click on the CMD app and choose Run as Administrator.
  2. In CMD window type in the following two commands hitting enter after each:
    bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
    bcdedit.exe -set TESTSIGNING ON
  3. Now that you have disabled DSE, go ahead and install VCOM USB drivers. (Run the “InstallDriver.exe” application inside the extracted drivers folder)
STEP 2: Flashing process

  • Now that you have the necessary USB drivers installed, extract both the ROM.Zip file and SP_Flashtool.Zip file on two separate folders on your desktop. Each on a different folder.
  • On your Infinix phone go to Settings>Developer options. Enable USB debugging. (If no Developer Options are present in Settings menu, Navigate to About phone>Build number. Click on Build number 7 times to activate the Developer settings. Go back one step into the now visible Developer options and enable USB debugging)
  • Connect phone to PC with original USB cable&let it load the connection. Then disconnect it
  • Now Open the SP Flash_tool folder. Right-click the Flash_tool.exe application and select ‘Run as Administrator’. This will launch the SP Flashtool flashing program which you will use to upgrade your device.
  • Click on SCATTER LOADING, this opens your folders. Navigate to the folder where you extracted the X551 or X507 Lollipop ROM.
  • On this folder select the file “MT6592_Android_scatter.txt” open and wait for it to load into the program.
  • On the Flash tool program, Change the  “download Only” drop down option to “FIRMWARE UPGRADE”
  • After all flash files have loaded into the program, Click on the “Download” button above (in green)
  • Lastly, switch off your phone completely. Connect the device to PC using USB cable. Now the flashing process will begin soon as the connection is is made.
  • Sit back and wait for a green “Download OK pass!” message as shown in the image below.
  • The flashing and upgrade process is now complete, disconnect and reboot your Infinix Hot Note X551 or X507 device running latest Lollipop ROM.

If you experience any trouble after flashing the new OS, go to phone settings or boot into recovery and do a factory reset/hard reset. Having severally updated both Infinix Hot Note X551 and X507 to Lollipop, I can gladly confirm both ROMs to be working smooth as candy with little to no bugs, a good effort in the right direction by the Infinix Mobility company!
