Proximity beacons discovery issue after firmware update

After I processed upgrade of my 3 beacons to
Firmware Version 4.14.1
Hardware Version F3.3
I can’t detect my beacons any more I tried with ios / android apps/ third party tools
I don’t see beacons are in the list.
I used estimote deployment ios.
Prior update I was able to use 3d party tools / estimote ios app.
Please advice.
Thank you

Update I was able to solve issue by removing and installing back batteries.
