i am using the macbook pro 2018 15”.

i was trying to reset everything in my macbook. so i went ahead and deleted the disk from the macOS recovery setting and it worked smoothly. i went to reinstalling the OS but i got impatient so i just turned it off hoping i could just reinstall later. but after going ahead and try reinstalling all i’m met with was a folder with question mark on the screen

i was met with more than 10 failed attempt to install the OS with various codes, such as -2005f, -2003f, -1008f.

< -2005f, -2003f, -1008f. > error

In Internet Recovery, these low negative thousands error messages indicate that your provided Wi-Fi Network is inadequate in some fashion, and cannot be used (for this purpose) in its current state.

Common problems include:

Hidden Network-name

required use of a proxy server to get Internet access

required use of a login page to get Internet access

Use of a login server or certificate to get Internet access

Use of PPPoE in the Mac to get Internet access (typically only applies to DSL)

Use of Fixed IP address rather than good old DHCP

Variance of the time by more than five minutes

Failure of Router to provide workable DNS server addresses, or providing 0.0.0.0 [may produce -2002f]

If you have an Ethernet port, you may in some cases be able to move your Mac close to the Router and connect to the Router using Ethernet.

The higher the number, the more obscure the problem.

Also, make certain the Date&Time and Time Zone are correct within 5 minutes.

Do you have access to another Mac?

If yes, create a bootable installer using this procedure How to create a bootable installer for macOS - Apple Support. That's the best way.

You can also use a PC and an app called Transmac for it. You'll have to download the macOS installer in Windows too.

One of the main problems is your slow internet connection. Since Big Sur install is about a 12GB download and the Internet Recovery does take a bit longer to download things, it seemed to you it wasn't doing anything.

Plus, during this download, if your connection suffers any interference/interruption, download gets cut and it doesn't resume, so you'll have to start over. Not a pleasant process, actually.

Remember, always have a bootable installer in hand when formatting your Mac. It's faster and way more reliable.

Not sure Big Sur will be any different, worth the shot, tho.

First try this sequence:

Unplug any peripheral from the Mac

Reset SMC like 2 or 3 times in a row How to reset the SMC of your Mac - Apple Support

Reset NVRAM 2 or 3 times in a row Reset NVRAM or PRAM on your Mac - Apple Support

Now try to run the installer again.

It shouldn't be necessary to reset these modules a few times in a row, but in my experience it sometimes changed the situation.

Have you created the installer on a Mac or a PC?

If on a PC, it’s common to see some problems and people have to create it again, maybe 2 or 3 times til it worked properly (don’t know why, it just happens).

If on a Mac, maybe something went wrong, try making a new installer to check.

Another option is, if you have access to another Mac and also have an external drive you can format, use this Mac to install macOS right to that drive. Once done, use that drive to boot your Mac and then let’s work from there.

You’ll then be able to use Disk Utility and check the internal hard drives, also check the rest of the hardware, etc.
