Short, practical explanation and steps based on the problem described by and .

Many Nokia phones accept special dialer/service codes and some of those codes deliberately perform resets. That would explain why settings "restore" right after you apply a change. Other causes are operator provisioning (SIM/operator pushes configuration on boot), using a tool that only changes a temporary profile, or trying to change files that are protected by the phone firmware so the phone re-writes them at startup.

Suggested troubleshooting and safe workflow:

  • Identify the exact model and firmware build before making changes. Different Nokia families behave differently.
  • Back up everything first (contacts, messages, calendar, user files) using Nokia PC Suite / Nokia Suite or another reliable backup tool.
  • Verify what type of "codes" were used: dialer MMI/service codes (some reset the phone), OTA/operator config, or firmware/file edits. On many older Nokias, certain codes trigger resets, so treat dialer codes with extra caution.
  • Test without a SIM to see if operator provisioning is responsible. If settings revert only with the SIM inserted, the SIM/operator profile is the cause.
  • For persistent system-level changes use the proper tools: official Nokia Suite/Software Updater for firmware, and Nokia service tools (Phoenix/Service Suite) only if experienced. Re-flashing or patching can make changes permanent but also risks bricking and may be irreversible.
  • Never attempt IMEI or illegal modifications. Always keep a recorded backup and the phone security code handy.

If software checks out and the phone still rolls back changes, re-flash the stock firmware (after backing up) or use the official update tool to install a clean image; that usually clears corrupted profiles that auto-restore settings.
