Judge Steven O'Neill twice refused defence requests for a mistrial, declaring that jurors could talk as long as they wanted over allegations that Cosby drugged and molested a woman at his suburban Philadelphia mansion in 2004 - allegations Mr Cosby denies.
The jury also requested to hear again Cosby's prior sworn testimony during which he admitted to obtaining Quaaludes to give to women with whom he wanted to have sex. (The jury has deliberated more than 40 hours since Monday.) "If they are hopelessly deadlocked, I don't think anything else is going to change that". He is charged with three counts of aggravated indecent assault and faces a possible maximum sentence of 15 to 30 years in prison if convicted of the charges.
The panel also asked to rehear parts of the 79-year-old comedian's deposition evidence.
On Twitter, Cosby himself praised his fans here and overseas.
On Friday, as jurors asked the judge to define "reasonable doubt" and attempted to bring an end to the deadlock on the three counts they were asked to consider, Cosby sent out a few tweets with photos of people holding signs up in support.
O'Neill is furious that Bill Cosby's spokesperson, Andrew Wyatt, made statements to the press Thursday, urging the jury to give up and declare a mistrial.
Cosby stands accused of three counts of aggravated indecent assault for allegedly drugging and sexually assaulting Constand, then a Temple University employee, in his Cheltenham home in January 2004.
They specifically asked for the testimony where Cosby admits to giving women prescription Quaaludes before sleeping with them in the 1970s.
"The jury can always write a note to the judge what the vote is, but the courts prefer not to have that information", Slotnick says. The reading took almost an hour on Wednesday.
As the deliberations dragged on, the scene outside the courthouse was one of prolonged boredom that was occasionally shattered by camera-wielding news crews swarming demonstrators and hurrying to the now-standard impromptu press conference.
In that call, Cosby told the mother what he did sexually with Andrea Constand in graphic detail, "trying to lead me to believe that it was consensual", she testified. "It's a deadlock", he said.
Though the preternaturally calm former collegiate basketball standout, who met Cosby while working for Temple University's women's basketball team, did offer some insight into how she had been biding her time. After three days of deliberation, the jury reported that it has reached a #Deadlock and was sent back to continue deliberations. The eight men and four women pulled from Allegheny County have logged 12-hour days Tuesday, Wednesday and Thursday. Cosby has said it was consensual.
"It's incredibly important to these jurors", the judge said.
The relationship became romantic after Constand's second visit to his home, he said.
But there are limitations to what judges can tell jurors, and that can vary from state to state. The victims of these attacks describe in vivid detail incidences in which Cosby drugged them before proceeding to sexually assault them.
As for the night of the alleged assault, Cosby addressed the pills he gave Constand before they started "petting". It was a tacit agreement Gonzales regretted until a friend expressed how sorry she was after hearing the story.
Constand said the pills made her drowsy, blurred her vision and her legs feel "rubbery".
The raucous scene outside the Montgomery County Courthouse, however, threatened to overshadow the jury's silent work within.
"I learned more from him than I did from her", she said during her testimony, in reference to a phone conversation she had with Andrea a year after the alleged incident.
