Unfortunately if you agree to a plea, you'll likely lose the ability to make that claim regarding your guilt or innocence since any good plea bargain would close that door. However, at the time of sentencing after you are a convicted, when you were told you would mostly likely get a suspended sentence (which is why you caved in so easily) and the judge says F* that, you get 20 years....then, you have appeal rights and language translation and being misled or even lied to is one of them likely in this type of case.Not only that, but having a translator prevents the defense from later claiming he didn't understand the questions.
