from homebuttons.

have you tried the full image flash ?

Yes i have flashed v2.4.0 full:
esptool.exe --port COM4 --after no_reset write_flash 0x0 fw_v2.4.0_original_full_image.bin

The device gives a HW init problem after unable to read the preferences?

I think the failure to load prefs is because you flashed 2301-112_v2.0.4_full_image.bin. That file contains specific info for device number 2301-112, which would make it incompatible with any other device. Flashing that put your device into some kind of factory mode, which isn't accessible to the user.

I suppose that , when @nplan reads this, he will send you the base firmware specific to your device (2301-048).
If you have an "old" full backup from device 2301-048, you could try flashing that.

The firmware from 2301-048 was a last resort, and is the only one that booted
All the other firmware's reported the invalid header messages prior to flashing the 2301-048 firmware

@FLeXO21 what fw version did you try to update from?

@FLeXO21 what fw version did you try to update from?

i try'd to update: fw_v2.3.0_original.bin, from this version: Firmware: v2.0.3

from homebuttons.

Versions 2.0.6 and earlier have factory parameters saved to flash. If you overwrite this section of the flash by flashing the firmware image at the wrong offset, the device won't boot. This is fixed in v2.1.0 and later by transferring factory data to hardware eFuses.

Here are the steps to fix your device:

1. Connect device with an USB-C cable to your computer
2. Go to https://nplan.github.io/HomeButtonsFlasher/
3. Put device to programming mode by holding BOOT button and pressing RST button. Boot LED should light up.
4. Select Home Buttons, V2.4.0 and Full Image
5. Click Connect, select ESP32-S2 from the list and click Connect
6. Click Install V2.4.0 ORIGINAL FULL IMAGE
7. Check Erase device and click Next
8. Confirm installation
9. Wait about 2 minutes for installation to complete
10. Close the browser tab and go to https://adafruit.github.io/Adafruit_WebSerial_ESPTool/
11. On device hold BOOT button and press RST button. Boot LED should light up.
12. Select 921600 Baud and click Connect
13. Select ESP32-S2 from the list & click Connect
14. In the first offset field enter 9000 and choose the provided NVS bin file
15. Click Program and wait a few seconds
16. On device press RST button. Home Buttons will show welcome screen.
17. Set up the device again according to the guide https://docs.home-buttons.com/original/setup/

After this procedure, the factory data is transferred to hardware eFuses. Erasing flash will not brick the device anymore, but it has to be programmed with the full image firmware afterwards.

Please send an email with your serial number to [email protected], so I can send you the correct NVS bin file. I don't want to upload it here, since I don't want other users flashing it. It's specific to the device serial number.

Wonderful! Thank you for providing such detailed information. I will make sure to follow the procedure you've outlined.

Update: After updating the device with the correct NVS file it's working again
