Flashing a classic Symbian device like the Nokia E71 (RM-346) is a great way to resolve boot loops, remove forgotten security codes, or restore the phone to a clean out-of-the-box state.
Before downloading any firmware, you must understand that the Nokia E71 came in multiple product codes (RM codes). The RM code determines which 3G bands and language packs your device supports.
Necessary for the PC to recognize the device via a standard Micro-USB cable.
