(adsbygoogle = window.adsbygoogle || []).push({}); So I have a problem. I recently went to 4.21 DEX to RTE on MW3. Then decided I wanted to go back to Kmeaw 3.55. Unfortunately I've lost my CEX flash dump because in the meantime by PC died and I lost everything. I've heard you can downgrade again but are there any solid tutorials I can follow?

Thanks.
