It's not possible to do a factory reset. However, you might be able to force an old firmware version to install like this.

OK. it was syncking approximately 45 min, gimbal became green in 15 min, so there were no different set of beeps. I Powered it off and saw a updating information on my app on a mobile. Upgraded it till version is 1.5.70+ and it works! thank you very much!!!
