Older firmware Released V1.1c (Sept. 17, 2017)

The file is here. Important! The file on the uSD card must be named e370_fmw.bin and if you want to have older versions, rename to something like e370_fmw_old_v11.bin first before writing the new version to the uSD card.

Installing new E370 Firmware

Please follow the directions below to upgarde your E370 to this latest firmware. You will need a FAT32-formatted uSD card of 32GB OR LESS. Larger cards may fail to load the firmware! Use a card <= 32GB!

  • Download the ZIP file, and extract it to the root directory of the uSD card. Do not change the name of the file.
  • Turn the power off to the E370.
  • Insert the uSD card into the connector 'label side up'.
  • Press and hold the encoder knob (like a data entry). While pressing the knob down, turn the power on.
  • When the boot screen appears, release the encoder knob. The E370 will scan for the file on the uSD card.
  • Once the file is found, the menu will ask if you want to upgrade, rotate the encoder to YES and click the encoder.
  • The E370 will erase the old firmware and install the new version. Your saved patches and User Banks are ERASED.
  • After the install is verified, you will be prompted to click the encoder knob to launch the new firmware. The Version diplayed at the bottom of the main screen is V1.2
  • Remove the uSD card.
