H1b transfer denied -move back to previous employer?

Hi, I’m currently on H1B. I left Employer A in June and joined employer B in August with H1B transfer notice. Now my H1B Transfer got denied with my current employer B. My previous employer A is ready to take me back and they never revoked my h1b. Can I go back to my previous employer to maintain my status ?

Is your I-94 still valid ?
