No, i meant EXACTLY what i wrote. Once you removed the (likely-problematic) map file ("once removed"), that you should proceed straight to loading the ORIGINAL firmware ("load orignal fw") then try to turn it on ("see if it now boots").

Further explanation:
  • I'm saying to not format it before re-loading the original fw, 'cos it probably doesn't need a format.
  • Cure fw cannot boot the device. In fact that's it's purpose. By halting the loading of files essential for the complete boot process, Mass Storage Mode is re-enabled so you can access the file system.
  • Removing the problem file (without a format) removes the problem but the device still can't fully boot until the original fw is again loaded.
  • If removing files doesn't work, THEN a re-format is done after re-loading Cure fw and finally original loaded again.
