The most common reaction to a Pure ban: factory reset the phone, create a new email, try again. It feels thorough. It is not. Here is the detailed technical explanation for why this approach almost always fails.
What a factory reset actually clears
A factory reset on Android erases user data, app installations, and resets the SSAID (Android ID). On iOS, a full device wipe removes most user-generated data. That sounds comprehensive — but Pure does not rely on those identifiers alone.
What a factory reset does NOT clear
According to the Android Developer documentation on device identifiers, several hardware-level identifiers remain stable across factory resets:
- Hardware serial number — tied to the physical chipset, cannot be changed without hardware modification
- Build fingerprint — encodes device model, manufacturer, OS version, and kernel details
- Sensor calibration data — gyroscope and accelerometer readings unique to each physical device
- IDFV on iOS — Identifier for Vendor may persist through iCloud restore cycles
Why new email and new SIM also fail
Changing your email and phone number replaces the credential layer of your identity. Pure's ban database operates at the device fingerprint level — your new credentials are simply linked to the same flagged hardware profile and banned immediately.
"I see this pattern every week: someone performs a factory reset, gets a new number, creates a new email — and their new account is banned before they even finish filling out the profile. The device is the same. Pure knows it immediately," explains Alex, an unban specialist with 4 years of experience.
What actually needs to change
Successful recovery requires addressing the hardware fingerprint layer — either through specific technical procedures or by working with a specialist who understands which identifiers are flagged in your particular ban record.
