We offer the flashing of new firmware for the 10bII+, 12c+, 20b and 30b.
These calculators have a port that allows the user to flash a new firmware. For that, a special cable is needed. The connector is in the battery bay.
Once the flashing has been done, the original firmware disappears. To be put back it needs to be flashed again. Hence the calculator guarantee is no more valid.
As there are several versions available at a given time, the customer has to supply via email the desired firmware to flash. The customer has to be aware that the firmware may contain bugs - of which TheCalculatorStore.com cannot be made liable.
