I'm trying to put 2 lines of code in a startup script for a ubiquiti router and all the extraction and recompile say successful but I get a rootfs crc check failed on update.
Looking at the install differences between the modded firmware and the original firmware I can see a Plen: 0 on the modded and a Plen: 0x00660000 on the original. Anyone with any ideas how to fix this? log below.
