Thank you for the tip! worked flawlessly.My GM1913 is not rooted, but still had the same issue (exact same GM1911_11.H.37... update name that you mention) - maybe due to udating manually via Oxygen Updater? What I did was enable the Advanced Mode in Oxygen Updater and setting my phone to 'OnePlus 7 Pro' (no India/EU/etc) and an update for GM1917 H.37 popped up. Installed it with the OpenPlus Tools (third link in the OU guide). Works like a charm, and update failure notification is gone![]()
