Macbook booting problem after a failed format.. (Please help me)

BIG PROBLEM!

Hey guys.. sorry to bother but I'm freaking out right now.. I have a Macbook Pro 13 from 2015 and I recently wanted to format it to factory settings to start off clean again but I don't know what I did wrong I think I ruined something.
I did everything the tutorial said I erased Macintosh HD - Data first then when I wanted to erase Macintosh HD I got an error saying that disk 2s5d or something couldn't be erased because of a kextcashe issue I don't know what this means.. I couldn't erase it so I just cancelled the process and when the laptop restarted I got a text screen saying "your computer restarted because of a problem..."

I pressed a button to continue and the laptop wanted to restart again but I keep getitng this message now and I don't know what to do..

I'm supposed to go to Japan for my studies in a few weeks and the laptop is crucial for it. being a student I don't have the means to buy a new one at this time so this would be horrible I really hope that anyone can help me. Thanks

Make sure that you've started up from internet recovery. If you're trying to use the built-in recovery, you won't be able to fully erase the disk as that's where the recovery environment is stored.

First off I thank you for your reply but I'm not a tech guy so I don't understand a lot of things. I have tried to format using the command R during startup method. Is this not good? How can I go to the internet recovery mode?

Internet recovery is command-option-R at startup.

Internet recovery is command-option-R at startup.

I started the laptop in this mode and managed to erase the Macintosh HD file but then when I went back and wanted to Reinstall MacOS I couldn't click on "continue" for some reason..

So I retarted the laptop again and I got a file icon with a question mark that keeps flashing..

EDIT: I managed to get it to the startup menu where it says "Internet recover starting it may take a while"
Then I get the logo of the world spinning and my wifi with the signal is there but I have no other options or other choices except for using another wifi but it automatically finds the right one but I can't click on anything to proceed.

Yep. ? = no bootable system.

You need to boot back to internet recovery mode and reinstall the OS.

If you have an ethernet cable, you could bypass wifi and likley increase performance.

1. Boot to internet recovery
- Command-OPTION-R at boot
- You'll need your wifi password
- It may take a while to load, BE PATIENT

2. ERASE the internal drive
- Open disk utility
- Go to view menu and if you see the choice "show all devices", choose it
(If you DON'T see it, don't worry about it)
- Select the TOP line on disk utility's "list" (on the left). This represents the physical drive inside the MacBook
- Click the erase button. IMPORTANT:
a. If you're installing High Sierra or earlier, use Mac OS extended with journaling enabled, GUID partition format
b. If you're installing Mojave, use APFS, GUID partition format
- Erase the drive and close disk utility.

3. Install the OS
- Open the OS installer and begin "clicking through" the install process
- The computer may reboot once or twice, and it will take some time, BE PATIENT.

4. Set up your account
- When the install is done, begin setup.

That should do it.
