help updating windows on my s620

[lp4u]

well i've bought a htc s620 on ebay and it has windows mobile 6 standard beta on it. CE OS 5.2.1215. i've tried installing wm 6.1 by kavana on it but at 3% it just exits and said image is corrupt but that very same image worked on a BT s620. i've tried application unlock on the s620 and it says "phone is not unlockable". what can i do to remove the beta version and install 6.1? btw i've to set a wrong date to be able to use the beta version else it will lock the phone and i won't be able to use it
