Few days back, the first android one smartphone in Nigeria, infinix hot 2 x510 received the android 6.0 marshmallow update. While the update seemed as a good news, it turned sour when it was discovered that the update comes with quite a lot of bug.

Some noticeable bugs includes lagging, unable to access files, stored names no longer showing on dialed list amongst others. We even discovered that IMEI cannot be changed easily like in the case of when the smartphone was running stock android lollipop OS.

Thanks to Richard who mentioned via comment that the IMEI can be changed after the phone as been rooted.

downgrade Infinix hot 2 x510 running marshmallow OS to lollipop

Anyway, we have received quite a lot of complaints and readers asking for tutorial on how to downgrade the OS from android 6.0 marshmallow to android 5.1 lollipop and we have decided to do justice to that.

After hours of trial by error, we finally arrived at a working process and yes, i already have it done on my unit of the infinix hot 2 x510 phone before coming on here to share the steps with you.

Without much talks, let’s hit the hammer on the nail but first, it’s very important you back up your files, apps and contacts before going on with this.

The flashing process will wipe everything on the phone leaving only the pre-installed applications. Thus making your phone look like the first time you bought it. Hence, backing up your files, apps and contacts is very important except you don’t need them anymore.

Steps in backing up your files, apps and contacts

For files like pictures, music, videos etc, i would recommend using your computer in copying all files to a separate folder on your PC.

You can just create a new folder on a directory on your PC with the name ‘My Infinix Hot 2 files‘ or anything else and paste the files in the folder. That way, it will be easy to locate them when you intend copying them back to your phone after the flashing process is completed.

For the sake of ease, i would recommend creating this folder on the desktop. It should be easy from that angle, or what do you think?

For contacts, you can back them up to your Google account so that when you are done with the flashing process and you input your gmail details on the phone, they’d reappear.

For apps, i would recommend using titanium backup or Apps back up & restore. In my case, i used the App Back up & restore app and when i was done backing up the apps, i moved them from the internal storage folder (that’s the directory where the apps are originally backed up to) to my SD card using the phone’s file manager app in other not to lose them after the flashing process is complete.

Done with that? You can then proceed with the requirements below. Oh! Least i forget, if you have already changed your hot 2 imei number to a bb imei, simply copy out the imei to a save place and simply re-change it after the flashing process is complete.

Requirements To Downgrade Infinix HOT 2 to Android Lollipop

  • A Computer
  • VCOM drivers installed on your computer. You can read this post for a step-by-step guide on how to. Windows 8.1 and windows 10 users would have disable Driver Signature verification first before installing the drivers.
  • Infinix FlashTool. You can download Here. I am recommending infinix flashtool because that’s what actually worked for me. SP flash tool couldn’t perform the flashing process on my two laptops till i decided on using the infinix flashtool which worked out well.
  • Infinix Hot 2 x510 AndroidOne Stock ROM. You can download here.
  • The Infinix Hot 2 phone and the original USB Cable

Got everything in place? Now, let’s move on with the steps.

Steps To Download Infinix HOT 2 From Marshmallow To Lollipop

==> First, as stated above, install the VCOM drivers on the computer. Windows 8.1 and windows 10 users would have to first disable Driver Signature verification before installing the drivers. After successfully installing the drivers manually, you can move on to the next step.

==> Using extracting programs like WinZip, extract the downloaded stock rom to a folder on your computer where you can easily access. Do same for the downloaded infinix flash tool.

==> Go the folder where you extracted the Infinix flash tool into and right click on the Flash_tool file and choose to run as Administrator.

==> When the programs loads up, click on browser and navigate into the extracted stock rom folder and select the MT6580_Android_Scatter file.

using infinix flash tool

==> Click on the start button and then, turn off your infinix hot 2 x510 phone and when the phone is totally turned off, connect it to your PC using it’s original USB cable and the flashing process should commence.

downgrade infinix hot 2 OS

==> Please be sure not to shake or disturb the whole process till the flashing process is complete. If the usb cable ‘mistakenly’ disconnects or shakes, it will brick the phone. Hence, you should leave it till the process is complete. When completed, you should get the check mark as seen in the image below.

When you get the check mark, you can disconnect your phone and turn it on. At first booting, it will take quite a long time but don’t panic, your phone is safe.

infinix hot 2 OS downgraded to lollipop 5.1

So, there you have it. You have successfully downgraded your infinix hot 2 x510 android phone running 6.0 marshmallow OS to Android 5.1.1 OS. The next step at this point would be restoring your files and synchronizing your Gmail account with the phone in other to display your saved contacts.

This OS is the stock android one OS that comes with the infinix hot 2 x510 smartphone out of the box. However, since it was discovered that the OS doesn’t support OTG cable, i decided to flash in another hot 2 x510 rom i would consider as custom because of the added features, User Interface and the OTG functionality. Some of us still very much need that USB On-The-Go (OTG) love.

Of course, you shouldn’t bother yourself with this if you just need your phone for it’s basic functions.


  1. mornin mr samuel. i recently upgraded my infinix x510 to 6.0,i later noticed the os has issues, so i tried downgrading to 5.1. when i load using sp flashtool or infinix flashtool the process will complete but the will not come on. plsss i need ur help

    • Are you sure you flashed in the right ROM file for the right version of the device? Remember the device is available in two variants.

  2. Boss, you are yet to answer me my question, it seems like after the new infinix update messenger and Facebook isn’t working. Including phone not charging while on

    • Slimzy, the last time i checked, the Marshmallow OS on the hot 2 wasn’t stable. Hence, i would advise you downgrade to Android lollipop. The information above should guide you though.

  3. hi, please the thing is my pc has not been able to recognise my phone since i upgraded to marshmallow… this is probably y der isnt any progress at all… way out please?

  4. hello sam. thanks for the post. am about to try this method to downgrade my infinix hot 2 x510.. am using a windows 8. i followed every instruction but when installing the VCOM drivers, i get an unsuccessful response at the final stage. maybe because my laptop spec isnt listed. but how ever, when i switch off the phone, and open device manager in my laptop, and connect via usb cable, i see this MT65xx Preloader but with the yellow caution. and will disappear after sometime. does that mean that everything is set?? should i proceed with flashing?? please get back to me thank you..

    • Precious, i only used the window 7 and windows 10 in doing the flashing process. For windows 8, i think you also need to disable driver verification. Have you done so?
