For anyone else looking at this I too am also having a similar issue - am attempting to update from v6.9 to v7.1 on both a BraX3 and a Google P8P. Note this is after manually updating the ‘updater’ app first (as per news post, etc) on both. The Pixel 8P has downloaded the update fine with no issues…
However the BraX3 fails and is unable to download the 7.1 update. Copying the URL and manually downloading it also fails - so the URL to the zip file in the updater is invalid, or the 7.1 zip file (for BraX3) has been removed from the server… This is the failing URL for anyone interested: https://gitlab.iode.tech/ota/release/-/raw/master/brax3/iode-7.1-20251225-brax3-ota.zip
Having a quick look for it manually…
EDIT: Alternate download link (Github) is here:
The issue is the file has been updated by the look of it but the link in updater has not. The latest file is iode-7.1-20251227 but the updater is pointing to iode-7.1-20251225…
