P8 (Colmi) Smartwatch hacking resources page.

P8 watch is one of many smartwatches supported by DaFit app (including PineTime). It is quite cheap (~$18 USD on aliexpress) and has full touchscreen, button and 240x240 color display. P8 is similar to PineTime, it could use the same software with minor changes.

How to flash with DaFlasher

Revert to original firmware

Daniel Thompson: (from waspOS)

"You will need to revert back to SoftDevice 5 and have a copy of the original firmware. I can help with the first bit but I didn't make any firmware backup (and couldn't legally share it even if I had) so I am not able to provide a copy of the original firmware. Anyhow, if you do have a backup then note that the zip updates in DaFlasherFiles cannot be applied directly to wasp-bootloader but we can return to the DaFlasher bootloaders by installing https://github.com/fanoush/ds-d6/blob/master/micropython/DS-D6-adafruit-back-to-desay-sd132v201.zip followed by ATCdfuFromSD2toSD5.zip . If you don't have a backup and decided you didn't like wasp-os then perhaps you could try ATCwatch to see if you like that better!"
