Frequently Asked Questions

Comprehensive answers to all your IMEI repair questions

IMEI Repair & Technical

Yes, when performed correctly. IMEI persists through resets and updates. Certain atypical flashes can affect it; follow the SOP provided with your SKU.

  • V3: Primary lane for IMEI + carrier
  • V1/V2: Older patches
  • V4: Carrier only (no IMEI)
  • V5: FRP + carrier (no IMEI)
  • OEM CPID: Honor/Xiaomi/Huawei — case-by-case

V3 on newer patches often requires matching Debug/Combination. V1/V2 usually not. V4/V5 not applicable for IMEI write.

Use model-correct TAC or the device’s original IMEI. Cross-model TACs can break band provisioning and network attach.

Carrier Unlock

Yes. Unlock status persists across resets and updates.

No. Blacklists are enforced at network level; provide a clean IMEI.

Demo Units & LDU Conversion

Yes. Conversion removes demo flags and writes retail IMEI; restores calls, SMS, and data where supported.

On supported lanes, yes. Keep stock firmware and avoid bootloader unlocks.

FRP & Security

Yes — primarily via CPID V5. IMEI write handled separately on V1–V3 or OEM CPID.

Knox features may be impacted depending on operation. Core telephony works post-service.

Legal & Compliance

Depends on jurisdiction and intent. Use only on devices you legally own. Check local law.

Refund if truly not possible. No refund for wrong inputs, blacklisted IMEIs, or policy violations.
