Inside the ZIP:
Transfer your verified Android 10 Custom ROM ZIP and the appropriate (Google Apps package) to your phone's internal storage or an SD card. Boot into TWRP Recovery ( adb reboot recovery ).
Upgrading or restoring your smartphone requires the correct operating system files. Android 10, originally codenamed Android Q, remains a popular, stable choice for many legacy devices. However, downloading firmware from unverified sources poses massive security risks, including malware and bricked phones.

Stick to the official sources: Google for Pixels, Frija for Samsung, XFU for Xiaomi, and the OEM’s own recovery pages for others. Take the extra 90 seconds to run a checksum verification. It’s the only thing standing between a smooth Android 10 upgrade and a completely bricked phone.
