Problem updating firmware 2.2

i have 3 beacons, i upgraded 2 of them but when i tried to upgrade the third one the message update failed appeared and now i can detect that beacon anymore.

How can i fix that??

Hi Sergio,

Beacon is probably in a boot state. Please check if you can find this beacon in the BLE Scanner. If yes, then try to update firmware with our SDK (https://github.com/Estimote/iOS-SDK/tree/master/Examples). If not, please write directly to me (witek[at]estimote.com)

Best,
