The SP Flash Tool will be able to transfer the firmware to your device trough this interfaces. Make sure you connect the device after you press the Download button in SP Flash Tool, as the communication interface will only be alive for 2 seconds if no data is being sent.

    Hey Buddy am installing sp tool and mtk drivers for the first time i want to ask you the part where you say now we have to uninstall the device we have installed i have not installed any device so do i need to follow the step or can you elaborate the need for this step….

    • Tehnotone.com says:

      Hi! If you were to let the device you install installed it wold be just a useless device in your Device Manager. What you actually need is the device drivers to be present in your system so that when you connect the real device to your computer it will use those drivers. That is why I said to let the box unchecked so the fake device is removed but the drivers are being left in the system, ready to kick in when you connect your device to your computer in download mode.

    Brother after following your instructions if i want to flash a rom etc use sp flash tool….can i just straight away install it or i have to disable windows signature enforcement every time and then proceed to flash or root phone etc cause i have a windows 10 64 bit

    • Tehnotone.com says:

      Hey! you have to disable windows signature enforcement every time (every time PC restarts). Tip: to avoid this you could use Sleep instead of Shut Down.

    I am trying to flash ulefone power with marsmallow and followed your instruction from start to the end but when loading scatter file i get an error. cant flash my phone. error says to check if the file is legal. any suggestions?

    hi there, i have a probelm to flash my ulefone power. the scattr file gives error and says it might not be legal

  5. Nico says:

    why my computer when i chose MTK USB port doesn’t install all the three driver but just MTK USB port (COM7)?

    • Tehnotone.com says:

      Normally all the drivers will be installed if you select either of them from the list at install, as the import in the operating system is being made at *.inf file level, so the files you download from above on this page contain all those drivers as a pack anyways. Just follow the tutorial and you will have all those device drivers in your system. They will activate automatically if proper device is being detected/in use.

    I’m following instructions you sent me on flashing my Vienna as the fingerprint software wasn’t working and I am at the stage where I plug in the phone to my PC. It recognises it for an instant and then I get a message the device is working normally which then immediately changes to Currently, this hardware device is not connected to the computer. (Code 45)
    To fix this problem, reconnect this hardware device to the computer. What can I do.

  7. fatalhh says:

    Hi…thanks for the tutorial…..I already have installed the drivers and I flashed a TWRP…successfuly….but I have a doubt….
    The drivers still in windows after install It….or when I turn off my pc and turn on a few days ago the drivers has been uninstalled …?
    I don’t understand when you say “You have to disable signature drivers everytime you go to flash a rom or a recovery or whatever…
    Could you please explain me…

    Hi… after installing win x64 driver, phone off then connect to laptop, suddenly the mediatek driver come up in device manager, BUT then suddenly disappear again when the charging info (on smartphone appear), Plz help 🙁

    • Tehnotone.com says:

      This is normal. You need to press Download button on SP Flash Tool BEFORE you connect your device. SP Flash Tool will start delivering the files after one second. If you did not press Download there is nothing to deliver. In this case after 3 seconds the phone will get bored waiting and it will disconnect then try to boot as usual.

    • Tehnotone.com says:

      This is a firmware-related error. Try with a different version of SP Flash Tool (older/newer) or with a different firmware package.

    Hi I have a bricked Jiayu s3w (on start freezes at Jiayu logo start screen – will not turn off except by battery removal). I have gone through all steps above (the device simply does not register connectability at any point. I have a second Jiayu S3 that registers and connects as usual. I have tried win 7 and win10. I have tried both latest Flashtool V3 and latest V5 with official jaiyu s3w rom and Extreme 2.0S3 scatter files. No communication with device. Device is switched off (ie battery out). No communication. Can you perhaps suggest something?
