ESP32-WROOM Installation

1. Install the ESP Flasher app on your Flipper Zero from the Apps catalog: https://lab.flipper.net/apps/esp_flasher
2. Download the flipper_http_bootloader_esp32_wroom.bin, flipper_http_firmware_a_esp32_wroom.bin, and flipper_http_partitions_esp32_wroom.bin files.
3. Disconnect your ESP32-WROOM and connect your Flipper Zero to your computer.
4. Open up qFlipper.
5. Click on the File manager.
6. Navigate to SD Card/apps_data/esp_flasher/. If the folder doesn’t exist, create it yourself or run the ESP Flasher app once.
7. Drag all three bin files you downloaded earlier into the directory.
8. Disconnect your Flipper from your computer then turn off your Flipper.
9. Connect your ESP32-WROOM into the Flipper then turn on your Flipper. (Optionally, turn on your Flipper first. Then, hold the BOOT button while connecting your ESP32-WROOM. If you do this, when you get to step 11, you can skip the Reset Board and Enter Bootloader steps.)
10. Open the ESP Flasher app on your Flipper, it should be located in the Apps->GPIO folder from the main menu.
11. In the ESP Flasher app, select the following options:
    • Reset Board: wait a few seconds, then go back.
    • Enter Bootloader: wait until the waiting for download message appears, then go back.
    • Flash ESP: if you do not see this option at the top of the main menu, then click Manual Flash.
12. Click on Bootloader (0x1000) and select the flipper_http_bootloader_esp32_wroom.bin that you downloaded earlier.
13. Click on Part Table (0x8000) and select the flipper_http_partitions_esp32_wroom.bin that you downloaded earlier.
14. Click on FirmwareA (0x10000) and select the flipper_http_firmware_a_esp32_wroom.bin that you downloaded earlier.
15. Click on FLASH - fast to flash the firmware to your ESP32-WROOM. Wait until the process is complete. If successful, the LED of the ESP32-WROOM will flash GREEN three times.
16. Lastly, on the ESP32-WROOM, press the RESET button once.
