Disclaimer: This tutorial includes flashing Android smartphone with a firmware ROM. If not followed correctly, it may lead you with a bricked device.

Advice and Required Tools:
Download Android 5.1 Lollipop firmware official final build: download from direct link or from torrent. Choose one of the following according to your Hot Note X551 device.
Build 20151218 – 20-Dec-2015 – with XUI 1.N.1.1 – Latest
Make sure you have your phone charged at least 50% to avoid any malfunction during flash.
Backup your phone if you have anything important. Flashing the phone will wipe all the data off.
Getting Ready
You may need to install MT65xx Preloader USB drivers, if you haven’t already, prior to start flashing MediaTek powered phone.
Extract firmware file, that you have downloaded for your device above, into a folder.
Extract SP Flash Tool, that you have downloaded above.
Make sure that your phone is Not Connected to the computer. But keep it near while performing following steps.
Steps to flash firmware:
Run SP Flash Tool as administrator from the folder you extracted in “getting ready” section above. Right click on the flash_tool.exe and choose Run as administrator from context menu. If any warning appears on startup about scatter file not found, ignore it.
Initial Screen of SP Flash Tool
Click on the Scatter-loading button on the screen as shown below.

In the Open File dialog, locate and open the firmware folder you extracted in “getting ready“section above and select the MT6592_Android_scatter.txt file. MT6592 is the MediaTek chipset in your phone

After loading scatter file, the firmware files will automatically be populated as below.

In this screen, select Firmware Upgrade from the list and then click big Download button. This will reserve your personal data/images after updating. If you don’t want to reserve your data or images on the phone and you want a fresh install of a ROM, use “Download only” instead.

You may need to choose other options like “Download only” or “Format All + Download” in above step but first read this tutorial in full to know when you may need to choose this option. There are consequences to know about.
The tool will be disabled for any more user-inputs. It’s now waiting for the phone connection.

Now is the time, you connect your phone to the computer. Make sure it’s turned off before you connect it. As soon you connect the phone to the computer, the flash tool should detect it instantly and automatically start the flashing process.
If you mistakenly connect the phone without turning it off, you can just turn it off now. Thing to consider is that, the flash tool will only detect the phone and start flashing when it’s turned off.

The flashing progress will be shown in percentage on the screen as above. It will take only a couple of minutes to complete.
Do not disconnect your phone once the flashing process has been started.
If the flash tool didn’t detect your phone, make sure your phone is turned off and is connected correctly. If it is, then you probably need to install drivers correctly as mentioned above in “getting ready” section. Now disconnect your phone, close the SP Flash Tool and follow this guide to install MT65xx Preloader USB drivers correctly. After installing drivers, you can start over with “steps to flash firmware” in this guide again. Don’t worry it’s a common issue.
Once the flashing process completes, it will provide you with the OK message and big Tick icon.

That’s it; at this stage, your phone has been flashed with the latest Android 5.1 Lollipop. You can disconnect the phone and boot it up.
Use the comments section below to give your feedback. I have tried my best to describe in a very layman’s fashion to make you understand every bit of the process. Still if you have any question or facing trouble to use this tutorial, ask below; I’ll sure try to help.
If you have failed with upgrading your X551 to Lollipop even after multiple tries. Try “Download only” option in step 3 above. This will remove all of your personal content/data/images on the phone. You can also try downgrading to previous version with Download Only option.
If you still fail which is not likely, you can perform the same steps above with Format All + Download in step 3 instead. This will most probably successfully flash your device but will leave you with corrupt NVRAM causing trouble with network communications including Invalid IMEI and bad WiFi address and WiFi NVRAM warning etc. Making you sure that if you use Format All + Download to flash ROM, you will not be able to make calls or text. This issue is also fixable but I am currently preparing a tutorial for that. If you are in hurry, you can go ahead and try it on your own or search the web for fixes. Follow the link below to fix this issue. Most of all, I or Tech Prolonged won’t be responsible for any damages this may cause. Do it on your own risk.
After being failed to flash my hot note for some days, this tutorial worked like a charm. Your drivers installing procedure from the other article was really helpful. Thanks
I've successfully flashed my phone to lollipop ? buh my only concern is my laptop can't detect my phone after the update
It's strange. Try changing the port on your laptop. As well restarting your laptop may also help.
I'll be very glad if you could help me out
after updating....im unable to boot my phone.....its showing XUI logo screen from last 2 hours.....plz help me if there is any solution.....i'll be greatfull....thnx
Sorry to hear that. You can try restarting your phone by long pressing power key. See if it boots up. If not, you can try the process again and make sure that you dont disconnect the phone before the flashing process completes. In fact leave it connected for a few more seconds after you see the OK message on flash completion. More importantly, do it when your phone has much of a charge.
ok....i'll do it one more time....thanks bro
good pm guys. i av reflashed my phone with the lollipop update, but yet am still stuck at the xui screen display. am really tired of this. pls, i need help. i actually flashed the correct rom (x551 - G808- A1 - L- 20151218 (1gb ram 16gb rom). pls, help me
someone help me plzzz
I'm stuck at the same boot loader screen which shows XUI logo. Tried the firmware upgrade with both X551-G808-A1-L-20151106 and X551-G808-A1-L-20151023 to no avail. Any help would be much appreciated.
It's mentioned clearly, both ROMs are for different devices. You should try only which one is for your device. You can try again with the correct one
Try only which is intended for your phone. Both ROM are for different models of Hot Note with 1GB and 2GB versions. Check and try again
Thank you boss. Lollipop is really good on my Hot Note :)
Need Help!!!!
I am stuck at XUI Boot Loader for my Infinix Hot Note Pro 2GB Ram , 16 GB Rom afterr flashing for Lollipop Upgrade 5.1. What should i do now ?
Hope you have tried with the correct ROM. The XUI logo screen stays for while for the first time. Please mention for how long did you wait for it?
The SP_Flash tool is not recognizing my device (infinix Hot Note) for the upgrade.
If your computer detects your phone, then make sure you have correct PreLoader USB VCOM drivers installed on your computer for SP Flash Tool to detect.
above article explains well how to install the drivers. please read carefully.
Use Format All + Download Option instead of Firmware Upgrade. That's
what i did to be able to get out of the boot screen issue i encountered.
It works very well.
Do not recommend using Format All + Download option. After FA+D, You will loose NVRAM and then face issues like Invalid IMEI. You won't be able to make or receive calls. and such a few more connectivity issues.... Then you will need to fix that all too if you use FA+D option to flash your phone.
I am also stuck on the XUI boot screen for over an hour.. I have faced the same error using several build for lollipop since October and now even on this latest 20151121 :(. The tutorial is followed exactly step by step. Please help. Thanks!
And proceed with the same above steps. Only use this ROM instead of the Lollipop.
I'll try to find some time and publish a video demo of the process as well as some more trouble shooting videos.. I believe you won't need for that and you will get the phone working yourself. Just try the stock KK ROM as suggested and inform me about the update.
I Use Format All + Download Option instead of Firmware Upgrade... It works... After update Lollypop, i was face new problem.. My IMEI numbers are gone.... Then i install MTKEngineerMode_v1.1 on my mobile.... After procedure, everything is fine... If anybody needs help, please contact me at +923214746225

I am really sorry that you have not been successful. I'll advise to flash back to stock ROM of KitKat. Download from here https://mega.nz/#!pEZxVDCD!5MF4-4JvWoemL_QYIcELrtcIa_nvo9mXMVRq7UNkpII
