ESP32 classic was my main intention for the bootloader update as that's the only platform we are moving from V3 to V4
I don't recall now if the change of offset was one of the things Claude tried while trying to fix checksum errors for the other platforms
I'll have to give it a try, unless you beat me to it @softhack007

I agree - might be better to initially launch the feature for esp32 only, and wait for more experiences before we also support bootloader upgrades on -S2, -S3, -C3, etc.
