Didn't think it was Patchable as it is encrypted

can anyone help me. before when I patched devices it worked but not now. I have 276cx, alpha 100x2 and alpha 50. I have tried the maps in a patched that works and the maps work.
Two options for your device
1. MSV: Weak - it verifies the validity of map signatures in a simple way, you can unlock an .img using gimgunlock-0.04MapSigPatch (without patching your firmware), but in case of unicode maps (CP65001) you must modify the CP value.
2. Patched Firmware :
This tool that allows you to "remove" from your device all the protections listed above, allowing the use on devices of any Unlocked Map, including NTU.

Download and unpack Astro430_Alpha50_350_Patched_JNX.rar on to the PC where your device is attached. Your desktop is easy
Be sure to remove & Back up All BirdEyes images (JNX files) currently present on
your device before applying the Patch
BirdEyes images can be restored AFTER flashing new firmware
Then you can drag-and-drop Astro430_Alpha50_350_Patched_JNX.gcd onto the WebUpdater "Short cut icon" on your desktop.

You don't say what device ,but maybe the older version worked because it included your device ,the updated version 2.20 adds more recent devices
