The official status is that you can not downgrade.

But if you take the risk you can do the downgrade via SP Flash Tool, just follow this steps:

Preparing

  • download an official stock ROM (MM stock ROM, LP stock ROM)
  • download and install phone drivers
  • unpack downloaded stock ROM on your PC
  • enable USB debugging option on your phone: like this
    • Go to Settings > About > Build number > tap it 7 times to unlock Developer options > then return to Settings > Developer options > tick the USB Debugging option

Flashing via SP Flash Tool

  • Charge your phone up to 80% and disable all those firewalls or antivirus on your PC.
  • Run as Administrator the flash_tool.exe, that you will find in the stock rom package.
  • Click on Scatter-loading and browse the scatter file MT6752_Android_scatter.txt
  • In the menu Option tab, go to Download, and put ticks in the DA DL All with Checksum both USB and Storage Checksum.
  • Now choose the Download only option
  • Now hit the green Download button
  • Now turn off the phone and remove the battery for at least 5 seconds, then put the battery back.
  • Connect your Phone to PC via USB, this will start the flashing process.
  • Once the process has completed, we will see a huge green check box.
  • Now we can disconnect the phone from the cable. Now switch on your phone, it will take 6-10 minutes for first boot.
  • You have successfully installed the stock ROM or Official ROM on Lenovo A7000 ROW version
