If you have replaced the firmware on a device before, you might have come across different file formats including .nb0 and ffu files. Most firmware packages use unique extensions and can be unpacked using special tools.
 One of such firmware package extension is .nb0 and .ffu which is our subject for today.

 If after downloading a firmware and it is in an unfamiliar extention; .nb0, you can use an official tool [ Software Update Tool (SUT)] that can unpack and flash .nb0 files.

How To Easily Flash Firmwares in .nb0 / ffu File Formats

  1. Make sure you have installed your device’s drivers to help you connect to the PC.
  2. Download Software Update Tool (SUT) and save it
  3. Now open the SUT folder, install and run the SUT-LR – Software Update Tool.
  4. If the .nb0 firmware is in a .zip or .rar archive, unpack it using Winrar and place the .nb0  or ffu file on your computer’s desktop so that you can easily access it later.
  5. Reboot the device to fastboot or download mode / bootloader. To do that, enable USB debugging, use Minimal adb tools or key combos[Power and Volume buttons] to enter download/fastboot/bootloader mode. If you want to use CMD on your PC, type these command to enter any of the above modes.(adb reboot bootloader.)
  6. Now connect the device to PC.
  7. On SUT-LR [Software Update Tool] homepage, click on  […] icon by the right or the horizontal empty box and select the extracted .nb0 or ffu firmware you downloaded. Then click Next.
  8. In the next page, select Erase User Data, Click Next.
  9. The flashing process will begin. Give it some time for all the images to be loaded / flashed to your device.
  10. You can then disconnect the device when done.

    Yes it would fix bootloop issues. In the meantime, I will try to get the M210 .nb0 firmware for you. Have you tried flashing the update.zip file via recovery?

But when i charge the unit and press vol – and power button it can go on fastboot mode. Thats why i think this is the suitable method t9 do flashing for i cant get into recovery. I dont know if the vol+ button is deffective that prevents me on doing so..please further guide me if i really missed a lot on this…thank you for your quick responses..

    Ok. Since you can only access 'fastboot mode', we would go with that. If you haven't installed fastboot drivers on your PC, download Fastboot installer here. Also download the Infocus M210 Update.zip here

    Install the Fastboot file and also tick the 'add shortcut to desktop' during installation for easy accessibility.

    After installaling the file, launch it. Connect your M210 in fastboot mode to the PC. Now type this in the cmd window and hit enter button.

    fastboot devices

    Your Infocus M210 fastboot id should now display. If yes, type these and hit enter after each line of command.

    fastboot erase userdata
    fastboot erase cache
    fastboot reboot

    Your device should now reboot. Give it some time to boot up completely. If that goes well or vice versa, please let me know.

    Yes, you should place the 'update.zip' file in the root of your Sdcard . Remember, you can only flash the zip file while in recovery mode. So if you have successfully entered the recovery mode, you can proceed. For the fastboot issue, install the Minimal Adb/Fastboot above and type the first command to check if your device is properly detected. If you have any question/issue, please let me know.

    You are welcome. If your Infocus M210 is now OK, you can continue using it. But if in future you encounter anymore issues, then you can install the 'update.zip file'

    I think the firmware on your M210 is having issues / conflicts. Try booting into recovery and install the "update.zip" file for your Infocus M210 so as to get a clean ROM. Just do that and let's see how it goes….
