Tablet on the MTK platform (MediaTek). To restore it, you only need FlashTool, no Odins, etc. RMB on "My Computer", Properties -> Advanced Options -> Environment Variables -> Create, name - devmgr_show_nonpresent_devices, value - 1. Go to the manager, look for the device and install the required driver. Physically disconnect the device from the PC. Run FlashTool, select the scatter file, check everything again and click download. We connect the device and wait. In case of failure, you may have to uncheck the firmware check in the flash drive. If it doesn’t work out, either disassemble and look for testpoints on the board, or give it to a friend / to the
upd service: if possible, before flashing, make a backup of nvram
