Your phone is a Mediatek device. So you need flash files with Scatter and SP Flashtool for flashing. You can get all here

Edit:

Steps below are for flashing Mediatek devices using SP Flashtool and a Windows computer:

What you'll need:

  • Download your device ROM files. You can find it here
  • Download SP Flashtool. Can be found here
  • Download Mediatek drivers, or here (for Windows 10)

How you'll do it:

Downloaded files should be ziped (rar, zip or 7z format), unzip then proceed by installing the drivers and . Also unzip SP Flashtool and the ROM file to somewhere you can access quickly - say in the Desktop.

  1. Go to the SP Flashtool folder and launch it. SP Flashtool opens on Download tab. On Scatter-Loading field, click on Choose. This will open a file selector dialog. Browse to the folder where ROM files are located. Select the scatter file. Flashtool should load all files now. enter image description here

  2. Click on the drop-down list and choose Format All + Download enter image description here

  3. Now power off the device. Click on Download then connect the device to the computer with a USB cable.

Flashing should start and simply wait for the software do its things.

The flashing ends when the green check mark pops up.

Note: This can be also solved by flashing a custom recovery, such as TWRP and manually mount the partitions.

  • Warning: Do not Format All + Download Mediatek devices https://blog.hovatek.com/so-whats-all-this-talk-about-meditek-secure-boot-and-da-files – alecxs Feb 15 '21 at 12:34
  • Thanks for pointing this out. However that article focuses more on MTK devices with Secure Boot. Wasn't common in the time this question was answered. – esQmo_ Feb 15 '21 at 12:55
  • Sure, didn't notice the date. Kindly update your answer. It is never good idea even on old devices with no secure boot you still lose device specific IMEI, Mac address, calibration data etc (see #464, #470) – alecxs Feb 15 '21 at 13:09
  • When you're dealing with issue like corrupted partition table, Download Only or Firmware update don't fix such issue which is/was very common on old MTK chips. So You had to Format All + Download. Never lost IMEI or MAC Address doing this. And this is something I do for a living. – esQmo_ Feb 15 '21 at 13:12
  • Also repairing IMEI on MTK is easier and can be done in seconds – esQmo_ Feb 15 '21 at 13:12
