Hacking Question Merge NAND Backup - CFW doesn't launch

[Groshaq]

Hi, I have a problem to launch my CFW (I use Kosmos V115), usually i have no problem but since i tried to update Smash CFW doesn't launch, when i tried to launch CFW i get a Black screen and nothing happen. I can go to the Legit Firmware, and it keep asking to update the console.

When i've made my NAND backup i had to split files (because of a lack of 300Mo ... --') but now i want to restore my NAND but it seems splited files can not be used to restore and i don't know how to merge files. i've tried with this
hekate2rawnand . sh script but it does not work.

Can someone please help me please ? I don't want to brick my console and for the moment i have only my 32Go (which need +300Mo to get all backup files), will order a 64Go today but even if i have it i don't know how to merge back up files

EDIT: Aaannd right after this post CFW launched properly .... but please i still have to know how to merge these files in case of real issues

The joiner sscripts listed here: https://github.com/CTCaer/hekate/releases/tag/v4.5 should honestly work just fine, but otherwise, back when I used a fat32 Card to dump my nand, I merged them using Fjoiner: https://www.igorware.com/file-joiner and Hekate restored the merged nand just fine. So, try that if the joiner scripts really won't work.
