[BUG] No rollback when migrating from [202210.01-LTS]

[Fienberber]

Hello,

I'm migrating from to the esp-aws-iot [202406.01-LTS] from [202210.01-LTS]. The previous integration was working properly so I know this is not an AWS issue.

We are using an ESP32C3 on our board.

Using the example works great. But I have issues while transitioning the devices from the old method. I think there is an issue with the NVS. After the first boot on the firmware using esp-aws-iot [202406.01-LTS], the OTA flags are at ESP_OTA_IMG_NEW.

This prevent proper response to AWS and retry the OTA. The device loop OTAs indefinitely. To fix this, I added custom flags to set the flag as ESP_OTA_IMG_PENDING_VERIFY if needed.

My issue now is with the rollback feature. If I OTA a bad firmware (crashing before partition validation) the board restart on the same partition.

During my tests, flashed using esp-aws-iot [202406.01-LTS] and transitioning to the same version, the rollback function works great.

Somewhere the version migration does something to the NVS but I can't find where.

Thanks in advance for you help.
