not working after some updates After updating the app i can not update firmware on 0x1000 offset. on serial output it shows no bootable partition found or not found any bootable app at 0xffffffffff . yeah that worked even "espflash" on the Android platform that also worked . i gess this is kinda bug or esp32 flash app forcing them to upload the bootloader first . This happens when I goes to flash Brumcilli Launcher and Micropython firmware. I also flashed bruce on 0x0 offset that worked

Hi, last update was few monthes ago, can you send me a mail with more details ? Thanks
Edit ok I see, its not update issue, but device wont boot normaly, you need to totaly delete the device flash, before retry. If that does not work try to flash a simple firmware from a PC.
Ok good, you are right, that may be a bug, I'll look at it thanks again !

Hi, actualy, you can't brick anything with any app, the issue you face is most likely because you just provided wrong bootloader / offset for your board and it cannot boot properly. The other app probably just provided you the offset for your board, this app requires you to know what you do.

Hi thank you for your comment.
Serial monitor can be tricky to connect your device to, and you must select the correct baudrate. If you got the correct baudrate and device is connected, try to push the reset button on your board...
What’s new
Added spiMode, spiFreq and flashSize options. Those only apply to the first file you flash, and it must be a bootloader (no support on BW16).
Not all values will work with your specific device, be cautious, it wont break anything though;
