TWRP on POCO F3 after formating DATA now Internal Storage shows empty and can't transfer the ROM

[St0RM53]

Hello. So i followed the guide to install Xiaomi.EU rom on POCO F3.
Steps taken:

1) Unlock the bootloader after 168 hours
2) Device is reset to factory after the unlock and i continue setup and don't SET ANY PASSWORD until main screen to activate developer tools and USB debugging again
3) I transfer TWRP and reboot to Fastboot mode
4) Using the console i install TWRP and boot into TWRP and install TWRP to ramdisk. So far internal storage is accessible on the PC
5) Then i go to Wipe->Format Data->Yes
6) Now Internal storage on the PC shows as empty (no size is shown), even after a reboot to TWRP and i've checked DATA folder shows as mounted.

I saw a guy on YT that used OTG adapter to copy the ROM into a USB drive then mount it on the phone and install it from there. However i don't have such an adapter.

What can i do?

Kind regards

Why didn't you use the instructions from this forum? Your procedure is bad.

Reboot the phone into the system

The instructions are:

ROMs for devices with locked bootloader:

• Unlock your first bootloader here http://en.miui.com/unlock/
• Install TWRP via Fastboot mode, then install our ROM
• Code:
  fastboot flash recovery twrp.img
  fastboot boot twrp.img
• TWRP Recovery TWRP or TWRP.ME
• FORMAT /data partition (NEVER wipe System or Persist!)
• Copy our ROM to the internal storage
• Install our ROM
• Reboot
• done

I did as far as:

• FORMAT /data partition (NEVER wipe System or Persist!)

But PC shows internal storage as empty/unknown/no size?

What mistake i made?

It's not a mistake, you didn't know that recent devices have a different installation instructions.
