Are there other options besides a partition action suit towards my two siblings who are joint tenants on a home?

I own a home in CA with two other siblings (joint tenants). I financed the loan, and paid property taxes. In which none of the siblings contributed to. I currently live in the home and one of the siblings recently moved into the property, just over a year now. I defaulted on the mortgage in Sept 2013 and filed for ch.7 bankruptcy in April 2014 and was finally discharged by Aug 2014. Through bankruptcy court, the trustee began to retain, a CPA, and a law firm but did not retain a realtor. The trustee sent a certified letter to two of the siblings if they were interested in purchasing the home. Prior to filing bankruptcy, I was aware the two siblings had no interest in the home, not wanting to purchase or sell. By being vindictive they are willing to walk away from their share so I don't receive mine. I recently found out that the trustee will no longer move forward with the forced sale because there is not enough meat on the home. There is at least a 100k equity and I think it's ridiculous how it will go back to the bank. Time is ticking and the house will go back into foreclosure proceedings. It is still in the bankruptcy stage since it's only been a day when I learned of the bad news. My attorney informed me I'm looking at living in the home for another 5-6 months. I need some guidance on what to do. What other actions need to take place in order for it to make things happen? I am practically unemployed. Can my attorney put a lien on my home to move forward with this case, that's if I have one? I really need my share for me to start my life over since I have exhausted most of my savings and pension. Help!!
