Protect personal data before returning a device
Back up and check your files, save fault evidence, then follow the maker’s account removal and erasure instructions. Remove personal storage and check the result before packing. If erasure fails, agree a data-handling arrangement before dispatch. Discuss supplier return arrangements with Cambridge China Bridge.
Back up and check access before changing anything
Copy the files you want to keep to storage you control. Include photographs, recordings, contacts, messages and app exports where available. Open the saved files from another device and check that the important material is present. A backup setting being switched on is not proof that your latest files were saved.
Check that you can sign into essential accounts elsewhere and receive verification prompts without the returning device. Transfer authenticator access and arrange replacement access to your phone number where needed. For a business device, involve the person responsible for company systems before removing work accounts. Use our China purchase return guide for seller approval and dispatch arrangements.
Save fault evidence without exposing private information
Before resetting, photograph the device’s condition and identifying label, and record the fault using another device where practical. Keep the original files with the order correspondence. Show the steps that trigger the problem, using a blank document or harmless test image instead of customer records, private conversations or household footage.
Ask the seller what evidence it needs before you erase the device, especially for an intermittent fault. Review screenshots and diagnostic logs before sharing them because they may contain account details or personal information. Send a redacted copy where appropriate and retain the original privately. For a device expected back after repair, see our warranty repair return guide.
Unlink accounts and erase using the exact model’s instructions
Consult the manufacturer’s instructions for your exact model and software. Check the sequence for signing out, removing account binding, disabling ownership locks and erasing local data. For a connected camera or smart device, check its companion app, shared users and linked services as well. Do not give the seller your personal account password or recovery codes.
Use the manufacturer’s full data-erasure or factory-reset procedure rather than only deleting visible files or resetting preferences. Government guidance says a factory reset should remove personal data from a smart device. Check that the device reaches its initial setup screen without your account or files showing, then leave it there. Treat that check as a practical check, not a guarantee that recovery is impossible.
Remove personal storage and check cloud copies separately
Remove your mobile network card, memory cards and removable drives before packing. Check camera card slots and any separate recording hub. Follow the model’s instructions for removing a built-in mobile subscription after arranging continued access to your number. Agree in writing if an originally supplied storage card must accompany the return, and erase it appropriately before including it.
Do not assume that resetting the device also deletes cloud recordings, shared albums or connected-service data. Review these separately through the relevant account, keeping anything you need before deleting it. Record which storage you retained and which accessories you included, so the seller can distinguish a deliberate omission from a missing item.

If erasure fails, agree the arrangement before dispatch
If the device will not start or its screen is unusable, do not describe it as wiped. Ask the manufacturer about supported recovery or remote-erasure options. Treat a remote erase request awaiting completion as unconfirmed. Check the required sequence before unlinking an account if that might prevent the erase from completing.
Tell the seller that data may remain. Ask who will receive the device, who may access it, whether testing can avoid personal data, and how retained or replaced storage will be handled. Request written confirmation of the agreed erasure work. Consider retaining removable storage, an approved local repair or another settlement. For sensitive business data, pause dispatch for an internal security decision; a seller’s promise is not evidence of erasure.
Frequently asked questions
Should I reset a faulty phone before returning it?
Save and check your backup and fault evidence first. Agree the evidence needed with the seller, then follow the manufacturer’s account removal and full-erasure instructions.
Should I send my memory card back with a camera?
Keep your personal card. If a supplied card forms part of the return, agree its inclusion with the seller and erase it appropriately. Record any card you retain.
What if my phone will not turn on to erase it?
Tell the seller that data may remain. Ask about supported recovery options and agree handling, access and storage arrangements before dispatch. Do not claim an unconfirmed remote erase has completed.
Does unlinking an account erase the device?
Do not treat unlinking as proof of erasure. Follow the model’s separate instructions for account binding, local data and cloud copies, then check the result.
