Even if you did not commit the crime, you plead guilty to it... so it would be up to the judge whether or not he wanted to set aside your guilty plea. But since you have already been sentenced, and have now violated your probation... its probably going to be too late to say you didn't do it.
You probably have a failure to appear warrant for your arrest now, and a probation revocation ( I assume you were put on probation and ordered to pay restitution). The only thing you can do is appear in court and ask the Judge to withdraw the warrant. Alternatively, you could hire a lawyer, who could add you on and ask the judge to withdraw the warrant. Then you will judt have to deal with the pending action.
You could TRY to withdraw your guilty plea, and start over... but this far down the road, most judge's will not do it.
One other option is to file an application for post-conviction relief, if you have new evidence that shows you didnt do it.
You can just stay in texas... but you should be aware that you are "on the run" and any time you get pulled over or anypolice involvemtn in your life, they are going to arrest you and extradite you to MO
