I'm not sure of the best way to fix this, but giving the user a choice of whether to compress the payload using LZMA is not a good thing in v2, since we don't have a way to modify the Config.lb or Config-lab.lb.
Having this option enabled for v2 means that half the possible configs are broken.
There are a couple of ways to fix it: 1. Disable the option for v2 and choose whatever matches the chosen Config.lb file 2. Add Config-lab-nolzma.lb Config-lab-lzma.lb Config-lzma.lb Config-nolzma.lb files to every target 3. Add Config-1M-nolzma.lb etc files 4. Add Config-buildrom.lb files like Config-abuild.lb files with replaceable __ROM_SIZE__ and __ENABLE_LZMA__ markers
