How it Works — Zero Drama

Predictable flow. Clear handoffs. Measurable outcomes.

1) Onboard

Create account, add funds, and open a ticket.

Use the Ticket Template below to fast-track screening.

2) Slot

We assign your device to the next available CPID session.

Live status posted under Server Status.

3) Remote

Technician connects; 5–10 minutes active work.

You stay on stock firmware and keep USB debugging ON.

4) QC & Sign-off

We validate IMEI persistence, signal/data, and SIM/eSIM.

Invoice auto-updates; refunds per policy below.

Legacy Methods — V1 / V2 / V3 / JDM

Context for technicians. We use the right playbook per device family.

V1Early Exynos/Qualcomm

Foundational CPID reconciliation for older Galaxy S/Note/A. OTA-safe if stock. Limited eSIM footprint.

V2One UI 4–6 era

Broader 5G coverage, better persistence across ODIN. US carrier variants increasingly stable.

V3Modern stacks (S23–S25 / Fold/Flip5+)

Best persistence and eSIM safety. Used by default unless device constraints suggest otherwise.

JDMLive Demo Units

Removes demo flags and retail-enables telephony/data. Hardware limits still apply.

Heads-up: We select the method internally based on model, baseband, and CSC to ensure durability. No root. No patched kernels.

Region Notes

US/Canada carrier SKUs: eSIM provisioning differs by carrier; persistence validated on stock firmware.
EU/UK: Banking apps often require SafetyNet/Play Integrity equivalents; stock firmware recommended.
India/Middle East: Multi-CSC devices (INS, XSG) supported; ensure correct APN post-repair.

FAQ — CPID Server & Operations

Operational clarity. No spin.

CPID is Samsung internal provisioning/identity domain for retail devices. We reconcile device identity to fix IMEI, remove carrier locks, or convert LDUs — without rooting or baseband hacks.

Samsung Wallet, Samsung Pass, and Secure Folder may remain disabled due to Samsung policy after repair. Core telephony/data and most banking apps work as expected.

Yes. The outcome persists through resets, ODIN flashes, and OTA updates, provided you remain on stock firmware. Root/custom kernels void coverage.

We never supply IMEIs; you provide your own clean IMEI. Blocking happens if the owner reports lost/stolen or due to external fraud actions — not from our workflow.

No. Clear KG/MDM first. FRP must also be OFF. We can handle those via separate services before CPID work.

Hardware faults (e.g., faulty RF chain), counterfeit boards, tampered EFS backups, or devices failing basic diagnostics on stock ROM.
