The Secret Menu 000000* — Full Guide to Submenus
This is the rarest and most interesting code on vintage Alcatel phones. Works on OT-Easy, OT-300, OT-501, OT-511 and many others of the same generation.
How to access:
- From the main screen, type
000000 - Press
*(asterisk) - The engineering secret menu appears
Available submenus:
TRACES — channel indicator menus Shows GSM cell parameters in real time: Cell ID, LAC, MCC, MNC, signal strength, channel quality. This is Alcatel's Net Monitor — equivalent to Siemens Monitor Mode or Samsung's *#0011#.
ARRETS — stops/halts menu Records system interruption events.
VIDER ARRETS — clear stops log Press OK → phone responds "This action is executed!" Clears the firmware event log.
CTRL CHARGE — charge control Shows in real time:
- Charger voltage (in mV)
- Battery voltage (in mV) A healthy battery should show approximately 3700-4000mV at full charge. Below 3400mV indicates a battery that needs replacing.
DAMIER — display test Full LCD test displaying a chessboard pattern to verify all pixels work correctly. Useful for evaluating display condition on a used specimen.
Language note: The submenu names are in French because Alcatel was a French company and the engineering menu was never localised for non-French European versions. "DAMIER" means "chessboard", "ARRETS" means "stops/halts", "VIDER" means "empty/clear".
Network Lock/Unlock Codes — ###765*XX# Series
| Code | Function |
|---|---|
###765*02# |

###765*07# |

###765*78# |

Warning:
###765*05#and###765*07#require the network code from the operator. Using###765*05#without the correct code may permanently lock the phone to the current network.

Frequently Asked Questions
What are the Master Codes 25228353, 25228352, 83227423? These are factory master codes that allow removing the security code set by the user or operator. Each code works for a specific family of models identified by the internal firmware code (HD1, HE1, BE1, BE3, BE4, BG3, TH3 etc). They are NOT network unlock codes — those are separate codes calculated from the IMEI.
Does the 000000* menu work on all Alcatel phones? It works mainly on pre-2004 models (OT-300, OT-501, OT-511, One Touch Easy, OT-535, OT-800). More recent models have different engineering interfaces. The code *#000000# (with asterisk and hash) opens the generic Service Menu on more models.
Does the * + 787292 procedure only work on OT-535 and OT-531? Yes — it is specific to only these two models. On all other Alcatel use the generic method (without SIM + *#0000*[CODE]#).
What does CTRL CHARGE exactly do in the 000000* menu? Shows real-time charger and battery voltage in millivolts (mV). It's the only way on vintage Alcatel to see the exact battery voltage without instruments — equivalent to Samsung's *#0228# or old Samsung SGH *#9998*228#.
Is *#364463# dangerous? It increases the software speaker volume limit — theoretically can stress the speaker if used continuously at maximum. For occasional use it is safe.
Is ###847# dangerous? Yes — full factory reset. Deletes all data. Use only when necessary.
