Guide to unbrick bootlooping SWR50 that is able to get into s1 bootloader/flash mode: 1. Power off device by holding power key until it reboots and then switches off with few vibrations 2. Connect to computer and check device manager - you should see unknown device 3. Install Sony PC Companion from this website support.sonymobile.com/us/tools/pc-companion/ Check if driver appeared in the Device Manager, e.g. unknown device will disappear and something like SEFLash will appear under usb controllers If driver is still not found - try to install Emma ----https://developer.sonymobile.com/services/flash-tool/ and get this driver to work 4. Go into PC Companion and click on "Support Zone", it will be downloaded 5. Then click on "Accessories software update" and try to update Smartwatch 3 (We might get new versions in the future, so it will be easiest to do so) UPDATE: Now you can reflash from Accessories page, it will ask if you want to refrlash. Keeping steps bellow for information purposes. 6. If #5 not working: Click on "Phone/Tablet Software Update" (yes, silly), click on "repair my phone/tablet", click Continue and Agree to all licenses, etc.... 7. Once presented by the list of phones - Select anything I guess, but I selected Xperia Z2, it should start downloading and then updating. 8. Once done it will say build number watch was flashed, in my case it was KNX01V 9. Disconnect watch and boot it. P.S. I guess they show phone selection just to provide instructions how to get into download mode and then flash based on the versions from bootloader. P.P.S I'm glad I tried this last resort thing after being ready to deal with verizon support and waiting for new watch...
