Bag of Waffles' browser tools for Teenage Engineering hardware.

Every tool runs entirely in your browser - no server, no accounts, nothing uploaded. Each one talks to your unit over its own USB interface and stores nothing about it.

Pick a device:

TX-6key readeropen → Reads the unit's AES-256 keys in the browser: the OTP key straight from your connected TX-6, the built-in key derived from your own official firmware file. It installs a tiny patched bootloader to do the read, and walks you through re-flashing the factory firmware afterwards. modifies the unit's firmware (reversibly) - use at your own risk
OP-XYdev modeopen → Walks you through enabling the hidden 3. dev menu in the OP-XY's te-boot, over the unit's own USB MIDI interface. No firmware is read or written, no keys are involved - te-boot just writes its own bootloader.dev marker. writes no firmware; the dev menu itself can be destructive - read the page
OP-1 Fielddev modeopen → Walks you through enabling the hidden dev entry in the OP-1 Field's te-boot, over the unit's own USB MIDI interface. No firmware is read or written, no keys are involved - te-boot just writes its own bootloader.dev marker. confirmed working on hardware
