Hi. Tried new to patch new FW 6.10 for GPSMAP64 with JNX loader patcher. There was no problem during update process but Can't Authenticate Maps appeared.
Looks like JNX loader does not work with new FW.
Is there any other solution?MTB75 Reviewed by MTB75 on . Universal Firmware Patcher for Protected Garmin Devices Universal Firmware Patcher for Protected Garmin Devices v.1.10 This is an universal firmware patcher for protected Garmin devices. Many devices recently have a strong firmware protection and cannot use unlocked maps because firmware requires .gma and has MSV ( Map Signature Verification). In this list (http://www78.zippyshare.com/v/CWAOqHso/file.html) you will be able to check if your device firmware requires this patcher or if it just needs gingunlock+mapsigpatch or simply an .unl file Rating: 5

Maybe not unlocked
MSV: Weak - it verifies the validity of map signatures in a simple way, you can unlock an .img using gimgunlock-0.04 (without patching your firmware), but in case of unicode maps (CP65001) you must modify the CP value (see the Temporary authentication of Unicode maps*).
Share the Frmware 6.10 as the latest offered is 5.60
