Bluboo X550 Software OTA Update – Firmware 150811
Hello, everyone! A new version of X550 firmware has been released after tests. I think some of you have received the OTA notification about the update. The new software is more stable and fix some bugs on former version. It won’t case crash or brick after you did it. If you didn’t get notification, go to setting – about device – check software update and you can get it.
Also we release the rom for manual upgrade. The new software version 150811, you can download it here https://mega.co.nz/#!XMxkDDTR!9B_8zY-re-yr8Pq0PyV7DReaATnPZ2RK30J5YCWuNOE
