Where can I download the software for Comrami c 705 tablet?

Hello, I have used conami c 705 tablet computer. It comes with Android 2.3 system, an expansion box, two USB ports and a network interface, which are used for inserting U disk and network interface. I use an expansion box to install games from a USB flash drive. Download QQ Android program (suffix is. Apk) is downloaded from Tencent official website on a computer with Internet access, and then copied to the memory card or USB flash drive of the mobile phone. Open the tablet and insert the memory card into the connector on the side of the tablet speaker. When plugged in, the tablet will block the memory card, and the screen will prompt "Memory Card Installed" and "Scan Media Library". After scanning, open "apk Manager", with "Install" in the lower left corner, and install according to the operation. If you are prompted for security settings, click "Allow installation of non-electronic market programs", and you can install most Android QQ. If you want to download more games, good luck with Baidu Android games.
