Guide: Verify and install Android 10 Q ZIP (custom ROM / update)
Warning: This procedure can brick devices or void warranty. Back up important data before proceeding.
Prerequisites
Device bootloader unlock allowed and you know how to unlock it.
Latest platform-tools (adb & fastboot) installed on your computer.
USB drivers for your device installed.
Battery ≥50%.
USB cable and working USB port.
Downloaded the Android 10 Q ZIP file (named update.zip or ROM.zip) saved to your computer.
If device uses recovery (TWRP/stock), know which to use.
Step 1 — Verify ZIP integrity
On your computer compute the ZIP’s checksum:
Windows (PowerShell):
Get-FileHash -Algorithm SHA256 path\to\file.zip
macOS / Linux:
sha256sum /path/to/file.zip
Compare the resulting SHA256 (or MD5) with the value provided by the ZIP source (official site or ROM author). They must match exactly.
If a signature file (.sig or .asc) is provided, verify using GPG:
Import signer’s public key:
gpg --import signer_public_key.asc
Verify signature:
gpg --verify file.zip.sig file.zip
gpg should report a valid signature from the expected key.
Step 2 — Verify ZIP contents (optional but recommended)
Inspect ZIP without extracting:
