Upgrade Infinix Hot X551 From Android Kitkat To 5.1 Lollipop OS – Here’s How To

Few days back, we wrote a quite detailed hands-on review of the android 5.1 lollipop OS on infinix hot note X551. That went viral as the brand had to share the post on her Facebook and Twitter pages. Ever since then, I have constantly been getting comments and mails in regards how to upgrade from android 4.4 kikat to android 5.1 lollipop on infinix hot note x551.

To be candid, the process is quite simple and easy. The basic thing is getting an idea on how the whole process works. Off-late, we have been doing a lot of experiment with out unit. At a point, the device got bricked. Not just bricked, hard bricked. Luckily, we were able to fix it and we shared the tutorial on how to. Judging by the comments, the tutorial has helped a lot of people so here’s more.

Upgrading Infinix Hot Note x551 From Android KitKat To 5.1 Lollipop

Here, we’d like to share tutorial on how to upgrade your infinix hot note x551 to lollipop OS. Please note that we are strictly based on the hot note device here (not Hot Note Pro). However, hot note pro users can follow same procedure but do not use same ROM file(It will brick the phone). You will have to download the particular ROM for your device. We have also been able to upgrade infinix Zero 2 x509 from Android KitKat to 5.1 lollipop and we will be sharing a tutorial on that very soon.

Requirements

  • A computer running windows OS. In our case, we have used windows 7 and windows 10.
  • A good USB cable. Preferably the same USB cord that comes with the phone.
  • Infinix Hot Note X551 Lollipop ROM file. Download Here. Extract to a folder on your computer after downloading.
  • VCOM Drivers Installed on your computer. You can read here for the files and how to install.
  • SP Flashtool downloaded. Please see this post for a detailed illustration on how to go about that.

If you have got all of those things in place, then let’s get started.

Steps


==> Make sure your infinix hot note x551 is fully functional and you have successfully installed the VCOM drivers on your computer. If you have got files on the phone, i would advise you make a backup first because following this tutorial will wipe all content on the phone except the pre-installed apps.

==> Navigate to the folder where you extracted the SP Flash Tool into, right click on the Flash_tool.exe file and choose to run as administrator.

==> When the program completely loads up, click on scatter-loading and navigate into the folder where you had extracted the infinix hot note x551 lollipop ROM files into. Choose the scatter file(MT6592_Android_scatter.txt) and wait till it completely loads up on the SP flash tool program.

==> Look properly under the scatter-loading file, you’d see a download Only option. Change it to Firmware Upgrade as indicated in the screenshot below.

==> Now, click on Download. Make sure your infinix hot note is turned on. Now plug in into the USB port of the computer.

==> Yes. Nothing happens right? Now, while the phone is still plugged into the computer, turn the phone off (not restart) then wait till you find some readings on the SP flash tool program.

==> Leave it to completely finish the readings. Do not try to stop or interrupt the process otherwise the phone will get bricked.

==> When the process is complete and you get the complete notification with a check mark, remove the phone from the computer and turn it on.

On first reboot, it will take a while. Don’t panic. Your device is safe. When it fully boots up, follow the on screen instruction in setting the device and there you have it. Android 5.1 lollipop OS on your infinix Hot Note X551. Pretty easy right??

Questions and comments in regards to installing android 5.1 lollipop update on the hot note device are welcome using the comment session and we will try answering almost every questions asked.

Please share, it doesn't hurt... :)

  • Thanks for this…. But I’m not sure I get the initial statement up there right…. Are you implying we should download using the ROM file link there for Hot Note Pro? How/where do we get the ROM file for Hot Note Pro

  • Pls the link I clicked to download the rom file is referring me to download an app*mega*.. Please am I on the right path?.
    Am using infinix hot note

    • Yes you are on the right path but do not choose to download the mega program. Instead, choose the download via browser option.

    • Dave, if you can get the direct link (.zip) and fix it on IDM, that may work. However, i didn’t use IDM in doing my downloads.

    • TJ, same process applies for the hot note pro. The only difference is getting the ROM file specifically for the Note Pro and not note x551. It is not compulsory but to stay on the safer side, you should be running stock android.

  • Yes, I also need a solution to the download problem. I tried to download using the browser option but failed midway. I downloaded up to 300mb and network service dropped, the downloading fail to continue. We would appreciate if a solution to use IDM is possible.

    • Haruna, that is possibly your network issue. The thing is, i do the downloads at night and i usually get a speed of about 700-900kbps thus, download is completed in about 30 mins. Just try downloading at night under a stable network and you shouldn’t experience any problems.

  • ==> Now, click on Download. Make sure your infinix hot note is turned on. Now plug in into the USB port of the computer.

    ==> Yes. Nothing happens right? Now, while the phone is still plugged into the computer, turn the phone off (not restart) then wait till you find some readings on the SP flash tool program.

    ==> Leave it to completely finish the readings. Do not try to stop or interrupt the process otherwise the phone will get bricked.

    Samuel, this is where i stopped. After clicking download, nothing happens. I off the phone but there was no readings on the SP flash tool program. I have waited for 30 minutes but nothing happens. Please advice.

    • Haruna, your phone should be completely turned ON before connecting it to the computer via a usb cable. You should only connect it after clicking on the download button.

      Now, when the phone has been connected, turn the phone OFF and leave it. The reading will automatically begin in about 5 seconds.

  • Yes!! Yes!!! Yesssss!!!! My Infinix Hot Note now running on 5.1 Lollipop OS. Thanks Samuel. I really appreciate you. My mistake two days ago was that, I was using Window 8 to upgrade that’s why I couldn’t finished the installation. But when I got window 7, every thing went smoothly.

  • Please sir, my infinix zero is not detecting my both sim. I tried checking my imei number with *#06# it showing null. I will kindly appreciate any help from u

  • I upgraded my hot note to lollipop but i couldn’t perform system update on the phone. It always remind me to update but whenever i tap to install the updates, it gives me this error,

    ‘Unfortunately, System Update has stopped’

    Please Samuel, kindly advice. Thanks.

  • Okay, this is what I got and it worked for me.

    I power off my phone and double click volume and power buttons just like when you want to take a screen shot when phone is on.

    A drawing of an engine will appear (Recovery)

    Press volume up + power button twice
    Some command in color writings will appear

    Use your volume button to scroll and power button to select

    select apply updates from cache

    select update. zip

    it will take like 10 minutes to install and optimize

    when complete select reboot phone

    now your phone is successfully updated

    Many thanks to Samuel who made me go online and make researches. I’m grateful.

    • Nice One Haruna, even though i am about putting up the post but your explanation here is really on point and it’s basically how it’s done. Thumbs up bro.

  • I am not able to connect my phone with PC after updating to Lollipop 5.1. I need to test my Android app on device. Need your help.

    Thanks

      • Not working! In fact when I go to Settings->Storage->Phone Storage-> And then select “USB Computer connection” from menu button located at top right corner. But nothing happens. No message, no output, no toast.

      • i was done this process in my innjoo fire plus 3g bu i am facing on problem when that flash tool process complete after that installation i start my cell my phon can not display but after 5 to 6 mobile auto ringing was start and continuously ringing nd ringing

    • Hello, the only upgrade available for the hot 2 is that via OTA update. Check through settings > Software update. If you find any, you can download and update.

  • Thanks a whole lot to everyone on this site and much gratitude goes to the admin cos I have been without my Infinix Zero2 X509 for almost a week. I got the update alert and downloaded the Lollipop firmware only for my phone to be bricked during the installation of the update due to it being rooted before. After going through forums and websites on how to unbrick the phone which has been unsuccessful, I stumbled upon this site and this article in particular and between 8 am and 10am, I go my phone unbricked and now use the new LOLLIPOP version of android.

    I really appreciate your level of true information.

    Thanks once again

  • Sorry for my naviety, but pls won’t I select the ROM I want to upgrade to from the sp flash tool?

    I already downloaded 4 different ROMs.

  • My downloads didn’t complete. It always breaks. In fact, the last one stopped even without nothing happening to the network connection.

    All the downloads stop midway at about 33mb.
    However, the one on the link Sammy Yoko gave above stopped the first time at 212mb out of 656mb; the second time, it stopped at 117mb.

    Can I continue like that?

    • Jonathan, use the download via browser option which is just below the mega logo (i think). That’s the medium i use and it’s been working fine for me.

  • Going through the comments on that link, some are complaining of poor device performance after upgrade.

    Pls is there a way I can extract and copy out the default ROM from another person’s Infinix hot 507?

    I have two people at my place of work who phone I can use to do that.

  • please i need urgent assistance after going through the process sucessfully my phone is not coming up i tried turning it on buh nothing is happening!! please does that mean my phone is bricked????

  • Chae!!!!! This is a very serious wahala.

    I started the download at about 2pm and it finished a few minutes to 6pm.
    The network wasn’t good enough. The downloads restarted and paused several times.

    The most painful thing is: after the download was completed, I realised the download also completed at 3.39pm yesterday.

    WTF!!!!!!!! 🙁 🙁

  • Finally downloaded the ROM and other necessary files.

    Tomorrow, I will upgrade my infinix hot x507. Guys, please wish me well because I stand the risk of getting my phone bricked.

    • Jonathan, lolz… Why are you making it seem as if it’s such a big deal? If you are very skeptical, be sure to make a back up of your device before flashing in the ROM and try not to interrupt the process in anyway.

  • Dears,

    Really this confuse most of us regarding upgrading to lollipop manually!!
    Is there anyway to upgrade OTA?

    I bought my Hot Note Pro 16+2 from Souq.com (Saudia Arabia) & now it’s pricked after 1 week after trying to upgrade manually, no power no charge, Don’t know what to do!.

    Is there any support team or agent here in Jordan?

    Thnx

    I eventually upgraded my hot note 16 + 1 today to the latest version (18/12/2015)

    pls help asap

    • Ernest,

      1. A few seconds
      2. The drivers are not properly installed. Please re-install and restart your PC before commencing with other steps.
      3. You will only see the green check when flashing is complete.

  • Help… My inifinix x551 has bricked.. it not flashing and if I remove the cable from the phone this is what I got brom error:s_brom_cmd_startcmd_failed (2005)
    [Brom] can not pass bootroom start command! Possibly target power up too early
    [Hint]

  • ==> Now, click on Download. Make sure your infinix hot note is turned on. Now plug in into the USB port of the computer.

    ==> Yes. Nothing happens right? Now, while the phone is still plugged into the computer, turn the phone off (not restart) then wait till you find some readings on the SP flash tool program.

    ==> Leave it to completely finish the readings. Do not try to stop or interrupt the process otherwise the phone will get bricked.

    Samuel, like Haruna, this is where i stopped. After clicking download, nothing happens. I off the phone but there was no readings on the SP flash tool program. I have waited and waited but nothing happens. Please advice.
