Note that the phone is somewhat knackered, and has been slightly glitchy with bluetooth recently. This appears unrelated to GadgetBridge and PineTIme.
First used Lup's pinetime-updater to get the PineTime into a known state - it's 'latest' bootloader and application, which is 0.7.1 at present.
Download the RC1 bootloader.bin and flash to 0x0000 using pinetime-updater's from downloaded file option. This gets me the new bootloader working v1.2.3 bootloader, still bringing me into 0.7.1
Download RC1 pinetime-mcuboot-recovery-loader.zip, connect GadgetBridge and use it to OTA. This failed on the first attempt soon after touching the screen to keep it from dimming, but worked on a second attempt when I didn't touch the screen. I don't know if that's an unexpected quirk of GadgetBridge, or just the glitchy bluetooth on this phone.
Download dfu-0.9.0.zip and use GadgetBridge to OTA that - I didn't touch the screen and it worked first time. I now have 0.9.0 and can validate it.
I now tried a few reboot cycles, both green to keep current version, and blue to swap between 0.7.1 and 0.9.0 - it seems smooth and reliable.
Long press to red during the bootloader gets me to the white InfiniTime logo. I then tried OTA to 0.9.0 again. The first time this failed with the progress bar just short of completion, and I had to long-press to reboot and try again. The second attempt failed at ~50% but the third succeeded, and I rebooted into 0.9.0 and validated. I suspect my iffy bluetooth again, but this also shows the process is robust - even with failures during OTA I could still eventually get a successful OTA and a working application without having to use the cable. Nice
I haven't tried the to/from wasp-os yet.
On a side note the combination of GadgetBridge and kdeconnect allowed the media controls in 0.9.0 to control the video in the desktop browser, but the scrolling of a title as long as 'WIP: bootloader improvements, factory firmware, OTA - Codingfield' is too fast for comfort.
I have also had problems with Bluetooth connecting to the Pinetime. My phone is a Pixel 3A. NRFConnect and Gadgetbridge sometimes seem to interfere with one another. If Gadgetbridge won't connect to the Pinetime I have to start NRFConnect, scan and connect with it, then exit NRFConnect and go to Gadgetbridge and then it will connect. I also have the problem with OTA uploads to the Pinetime failing sometimes. A retry usually works but there was an occasion I had to try five times before it worked.
