This is an approved method for unlocking the Siemens Dual-Phone DP450 defined and released by Gigaset Communications, the original supplier of the phone to Tesco.

Some people experience problems with the firmware upgrade where the process does not complete. If after 30 minutes your handset keeps flashing 'Base 1' you will need to power cycle your phone base by disconnecting the power for 10 minutes and then reconnect it.
Allow the phone to boot, we recommend leaving it a further 30 minutes to boot and upgrade. If your handset is still flashing 'Base 1' after this time, you will need to pair the handset to the base. To do this, follow the procedure below:
On your handset:
SETTINGS HANDSET REGISTER
→→
On your base:
Hold down the blue button for 30 seconds.
If all goes well, your handset should now be paired and you should be able to make a call.
