There are only a few ways to stop the writ of possession.
1) You can file the supersedeas bond. However, be aware that the District Clerk has nothing to do with the County Judge, you have to go through the County Clerk's office to file anything with the County Judge. I'm not sure what stage you are at so you may have to file the bond with the Court of Appeals and have them issue a stay of the Writ of Possession. Failing to file a supersedeas bond always allows a civil judgment to proceed forward even though you appeal.
2) If you have some kind of grounds for it, you can ask a district court or a federal court, depending on the grounds, to issue an injunction staying the Writ of Possession. I couldn't even start to guess what those grounds would be because that would take a complete evaluation of all of the paperwork, testimony, and court filings so you'd have to get a local lawyer involved; or
3) File a bankruptcy. A bankruptcy immediately and automatically stops everything and allows you to sort out what's going on. The stay from the bankruptcy judge is automatic upon filing and you have to notify everyone involved and then everything moves to the bankruptcy court although the other side can ask that the stay be lifted at some point and you can ask that you be allowed to continue the appeal and leave the stay in place.
Those are your options at this point.
