How to Install Firmware on Prestigio PMT3677 tablet

  I bought this tablet (Prestigio 7.0 ultra+ PMT3677) quite cheaply, so i expected some problems with it. After a short period of use it became apparent that it's horribly slow. Especially due to the fact that, like many android systems, every program wants its share of tablets resources (which are already low) and because they are preinstalled its impossible to remove them without rooting your phone.
  So one other option includes resetting tablet to factory preset and/or reinstalling the whole firmware.
  I will give the instructions as it worked for me.

! This will delete all your files on the tablet, please make a backup.

So, lets begin:

1. Download and install LiveSuit --> download link
2. Download Firmware .img file for PMT3677 --> download link (official Prestigio site)
3. If needed, download and install adb universal drivers  ---> adb driver
           This ensures proper connection between the device and the computer.
** For some reason this works on earlier operating systems and not on Win8 and Win10.**
Open LiveSuit
1. Follow the instructions, upon asking, select mandatory install, select and locate firmware .img file.
2. Power of tablet, connect to computer via usb cable.
3. Press and hold volume up/ + button until LiveSuit acknowledges and starts the install.
       If nothing happens start from step 2 again, and maybe try different buttons.
4. It will prompt a file format, press yes.
5. Wait till done.
      Upon failure redo the process.

This is how it worked for me. I do not take responsibility if you brick the tablet!

You have been warned!
Thank you!
