That script probably won't fix the issue. It's used to clean up sysMMC in case you've installed pirated content, homebrew forwarders and alike (i.e. the stuff that shouldn't be possible without custom firmware) so that you can get as clean as possible sysMMC in order to possibly be able to access online services, provided that your console wasn't banned or flagged before.
So AutoRCM is off, that's good. Battery... that's weird. I wonder if not being able to boot into OFW is due to the mismatched fuse count? Unfortunately, this is probably beyond my level of troubleshooting. You should probably wait for someone else to reply in case I'm wrong. ^^
But, if I'm correct, the usual way to fix that issue is to boot into sysMMC CFW and run Daybreak to update the firmware to the latest version. I'm not sure what's going on in that Kefir pack but you can backup
atmosphere,
bootloader and
config folders from your SD card to your PC, and remove them afterwards from the SD card. After that grab the fresh
Atmosphere and
Hekate builds and paste them onto your SD card.
Before you launch Daybreak, you'll also need the firmware files for 17.0.1 that you can download from a certain site we aren't allowed to link here (quick Google search is all it takes to find it), create a folder on the root of the SD card called firmware (it can be anything, really, as long as you can easily find it) and extract and copy the files over to the SD card.
Here's a written guide in case you need it.
