This tutorial is meant to show you how to install your Android phone drivers on PC to allow your Computer to detect your smartphone properly, this is especially for those who own a BLU smartphone and find it difficult to find exact BLU drivers to allow their PC to detect their phone so they can use tools such as smartphone flash tool to reinstall or flash a ROM to update or to repair their phone that’s stuck on boot or to perform a backup or IEMI repair. We will be using MTK USB driver to allow your PC to detect your phone.
The Issue
Have you ever attached a device or your phone to your computer such as a BLU smartphone and hear the windows sound for when a new device is detected only to have it disappear with a sound after a few seconds. Also if you go into device manager you notice an unknown device under other devices that windows cannot identify after your phone is plugged in with a yellow triangle and exclamation. Also if you are using a tool such as SPF flash tool it will not work as your phone is never detected because the drivers are not installed.
What will we be doing?
We will be installing the MTK USb drivers so that Windows can communicate with your phone properly and allow for the tool that you are using to work.
What will you need?
1. Your Android smartphone.
2. The Original USB cable that came with your phone.
3. Download the MTK usb driver
Alternative Sources: Source 1, Source 2, Source 3
4. A reliable computer.
How to install MTK USB driver ?
1.Download the MTK driver from the link given above and if the file is zipped unzip the consents of the download, you can do this by right clicking and choosing extract here. The really important file inside the folder that we will need is the :MT65xx Preloader Driver or folder, note if you do not install this driver or do so correctly your PC and Smartphone flash tool will not detect your phone correctly. The file is inside the main folder in a file called: All MTK drivers.
Also don’t worry as the drivers will work with any version of windows you have including windows 10, Windows 8, windows 7 or older, I have tested trust me on this.
2. Connect your Android smartphone to the PC and you should hear a sound indicating its connected, next go to your windows control panel and find device manager and if you see nothing simply disconnect and reconnect your phone, you should see a device pop up with a yellow triangle.Its often called Mtk preloader or something it will disappear however after a few seconds and the phone charges.
3.Now timing is important as soon as you disconnect and reconnect your phone right-click the device that pops up and choose update driver software.Now choose browse my computer for driver software and choose the folder that you downloaded and extracted above and go to the All MTK drivers folder and choose the MT65xx Preloader folder. From here click OK and next and allow the drivers for your phone to be installed.
If you get a pop-up about windows cannot verify the publisher simply give permission to install anyway and that’s it, the process should complete and your phone will be fully detected and you can go back to flashing your device or whatever else you were doing.
Now in some cases if you have gotten this far you may realize that for some reason the drivers are not installing as they are being blocked by windows itself in these cases you will need to follow this article and disable driver signature enforcement.
Try the Following if your Phone is still not being Detected after the Driver Instillation
If you installed all the drivers but your Computer doesn’t seem to recognize your phone, try the following trick: Remove the battery from your phone. Place the SP Flash program in Download. Then hold down the VOLUME UP button while you connect the USB cable to your phone. Slip the battery into the phone while still holding the Vol+ button. Di not let the Vol+ button go until the flash begins (you will hear the chime on the laptop and you will see the red bar at the bottom of the screen). Once the flashing process begins, you can release the Vol+ button and let the flash complete.
The reason this works for stubborn cases is that when you hold down the Vol+ button when the battery is out, this FORCES the laptop to load the PRELOAD USB VCOM driver that the laptop uses to recognize the phone for flashing purposes.
If you set the flash tool to Format+Download, it will not in all cases make the computer recognize the phone. If it does It’s just a coincidence. The reason I am warning you about this setting is that reader’s may suggest it and in SOME phones and some versions of the flash tool, you may end up hard-bricking the phone if you format it! Formatting is the LAST RESORT. You should try Download first. If that doesn’t give an error, then the next thing you try is Firmware Upgrade in the flash tool. Only if that too fails to flash the phone, only then would you attempt the Format+Download option.
But the bottom line is that if you’ve got the right drivers loaded but the phone without battery is not recognized when you connect to the laptop, it’s because the Preload driver failed to load. Holding down the Vol+ key is the extra step you need to take to force the Preload driver to be loaded. If that still doesn’t work, then try also holding down the power button just after the Vol+ button, then connect the phone, then slip in the battery. Remember to release the buttons once the phone connects.
If none of that works, then you did not install the correct drivers.
Try this if your phone keeps connecting and Disconnecting:
If your phone is connecting and disconnecting repeatedly or the phone is recognized but not long enough to flash. In some of these cases, using the Vol+ may help as long as the flash has enough time to start and their is sufficient power to the phone.
However, users with the connect/disconnect loop may have a hardware problem that is causing the issue. The issue has to do with the amount of power that’s coming from the USB port across the USB cable to the phone. You see, the USB port on a computer has very low power and there are reasons the amount of power is dropping off to insufficient levels causing the phone to disconnect. Here are some of the reasons and the simple method to fix each one:
1. The USB port on the computer is loose or dirty. Either choose a different port, or clean the port and bend the little tabs inside the port so they connect more firmly with the USB cable.
2. The USB cable is way too long! I’ve seen reports of people using 4 foot long USB cables. Not a good idea! Use as short a USB cable as you can to connect your computer to your phone.
3. In some computers, the USB port simply does not have sufficient power to keep your phone connected. In this case, use a [easyazon_link asin=”B00REX6DRK” locale=”US” new_window=”default” nofollow=”default” tag=”blogtechtips.com-20″ add_to_cart=”default” cloaking=”default” localization=”yes” popups=”yes”]POWERED USB hub[/easyazon_link]. A powered hub may also help with longer cables.
4. The problem may be that some readers are not removing their SD card and their SIM cards before trying to flash. If there is sufficient power across the USB cable, this should not be an issue. But in some cases, the SD and SIM slots may draw a little bit of the power that the phone needs to stay connected. So by all means, remove your SIM and SD cards and see if this solves the issue.
