I’m home now and my Flipper read my FlexUG4 on the first try and was able to set the standard config and wipe it with no problem. Now my phone recognizes it again. It must have been and issue with my PM3. My Flipper has a @Hamspiced MFGC v0.1 on it
@Iceman One my trip I was using a PM3 easy 512K with the latest Iceman firmware and one of @Hamspiced 's v3 flex MFGC 's. I also have an RDV4 running your firmware. I love the RDV4 and usually use it for everything but it has an even harder time reading the FlexUG4. I haven’t seen any improvement on the RDV4 with the MFGC or the RSP (although I haven’t gotten the RSP to make a difference on anything so far). But the MFGC works great on the PM3 Easy.
