Flashing a Samsung Galaxy S7 with Android 10 involves installing a custom ROM, such as LineageOS, that is based on Android 10. First, you will need to unlock the bootloader of the device, which will erase all data on the phone. Then, you will need to install a custom recovery, such as TWRP, which will allow you to flash the custom ROM. Once the custom recovery is installed, you can download the Android 10 custom ROM for the Galaxy S7 and flash it using the custom recovery. It's important to note that flashing a custom ROM can void the warranty of the device and may have risks, so it's important to thoroughly research and understand the process before proceeding. **

In most cases, a PC does not need 10 cores. For the average user, a PC with 4-6 cores is usually sufficient for everyday tasks such as web browsing, email, and word processing. However, for more demanding tasks such as video editing, 3D rendering, or gaming, a PC with 8 cores may be beneficial. 10 cores would be more suitable for professional workstations or specialized applications that require a high level of multitasking and processing power. **

The speed of a Windows 10 PC can vary depending on several factors such as the hardware specifications, the number of programs running, and the overall system maintenance.
