Due to forum rules on breaching Garmin's software End User Licensing Agreement, we cannot actually make the flash kit for you however i can give you generic advice along with the required update.txt content as below:

You need to save the individual BINs from your patched firmware using RGN_Tool or [Only registered and activated users can see links. ] and appropriately name the fw components as 14.bin, 127.bin & 158.bin. Read this thread to understand the process of flashing BIN files from SD card and how to make the kit: [Only registered and activated users can see links. ].

The txt commands given will delete any gupdate.gcd if present on the device, dump a copy of the device's non-vol memory region, and then flash the 3 fw regions with the BIN files you place in the root of the SD card.

Of course you must be sure that the patching of fw_all.bin intended for region 14 (0x0E) has been properly done prior. You've stated Drive 5 Plus has HWID 2586 which is shared with Drive/DriveSmart 51 and Drive 5S it seems and therefore all use the same firmware.
