Data Recovery & Customer Documentation

Protecting what customers actually care about

Module 10 of 1275%
01

Welcome

Welcome to Module 10. Customers rarely mourn a phone. They mourn photos. This module covers realistic data recovery and the paperwork that protects you both.

02

Learning Objectives

  • Explain what encryption means for recovery odds.
  • Perform safe pre-repair backups.
  • Write consent forms and repair notes.
  • Set honest expectations before work begins.
  • Handle customer data lawfully.
03

Prerequisite Knowledge

  • Module 9

If any of these are unfamiliar, review the Foundation level first.

04

Vocabulary

FBE
File-Based Encryption used by modern Android.
Secure Enclave
Apple's hardware key store, making off-device recovery infeasible.
Chain of custody
The documented record of who held a device and when.
Consent form
Written authorisation for actions that risk data.
05

Why This Matters

Promising data recovery you cannot deliver is the fastest way to lose a business. Honest limits build trust and referrals.

Lesson Content

Lesson 1What encryption changes6 min

On encrypted devices, data is unreadable without the device's key, which is bound to hardware and the user's credential.

If the device boots and the customer knows the passcode, recovery is usually possible. If not, be honest: it usually is not.

Lesson 2Backup before everything5 min

Use adb backup where supported, MTP copy when the device boots, or vendor tools. Verify the backup opens before you proceed.

Lesson 3Documentation that protects you6 min

Every job needs: intake record, consent, work performed, parts/firmware used, verification result, and handover signature.

Keep records for at least twelve months.

Visual Explanation

Does the device boot?
  ├─ yes ─► passcode known? ─► back up now
  │             └─ no ─► no lawful recovery
  └─ no ──► can it reach recovery/ADB?
                ├─ yes ─► attempt pull
                └─ no ──► set expectations honestly

Real-World Example

A customer says: “Just get my photos, I don't care about the phone.”

What is your first sentence back?

An honest probability statement, in writing, before any work starts.

Possible causes

  • Encrypted storage
  • No cloud backup
  • Failed NAND
09

Technician Tips

Technician Tip

Quote diagnostics separately from repair. Diagnostics are billable work.

Technician Tip

Never begin recovery attempts without a signed consent form.

Did You Know?

Modern Android encrypts by default at first boot, which is why chip-off recovery has become largely obsolete.

Common Mistakes

Common Mistakes

  • Verbal-only consent
  • Overpromising recovery
  • Keeping customer data after handover
11

Safety Notice

Safety Notice

  • Handle customer data under applicable privacy law; delete it securely after handover.
  • Never access customer content beyond what the repair requires.
12

Hands-on Practice

Exercise 10 — Consent pack

  1. Draft a consent form
  2. Draft a repair-notes template
  3. Draft a handover checklist
  4. Test all three on a real job

Mini Project

Mini Project — Shop documentation kit

  1. Assemble intake, consent, notes and handover documents
  2. Add a privacy statement
  3. Run five jobs entirely on this kit
15

Reflection

  • Where have you over-promised before?
  • How will your intake script change?
