iCloud delete and remove device and photos

Question

Inexplicably I wasn't able to enter my 4 digit password on my iPhone anymore. I tried so many times that my iPhone was deactivated.
I powered off my iPhone and restarted it, but no chance.
Afterwards I asked to delete my iPhone from iCloud.com, but first I requested to erase the phone.
What happens to my iPhone if I've erase my iPhone via iCloud ("Find my Phone") and afterwards I also delete my iPhone from my iCloud account?. Does the request to delete my iPhone still apply?

Answer 1

Yes, the iPhone will still be erased - when you start your iPhone you'll be asked to set it up again as a new one.

Erase using Find my iPhone

If you enabled Find My iPhone through iCloud, you can use it to erase your device.

1. Go to icloud.com/find.
2. If prompted, sign in with your Apple ID.
3. Click All Devices at the top of your browser window.
4. Select the device you want to erase.
5. Click Erase [device] to erase your device and its passcode.
6. Now you can either restore from a backup or set up as new.

Answer 2

When deactivated because of too many passcode attempts, you can also:

Erase it via iTunes:

1. Connect your device to the computer you synced with.
2. Open iTunes. If asked for a passcode, try another computer you've synced with, or use recovery mode.
3. Wait for iTunes to sync your device and make a backup. If it doesn't, learn what to do.
4. Once the sync and backup have finished, click Restore [your device].
5. When you reach the Set Up screen while restoring your iOS device, tap Restore from iTunes backup.
6. Select your device in iTunes. Look at the date and size of each backup and pick the most relevant one.

And via recovery mode:

1. Connect your iOS device to your computer and open iTunes. If you don't have a computer, borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider.
2. While your device is connected, force restart it: Press and hold the Sleep/Wake and Home buttons at the same time. Don't let go when you see the Apple logo — keep holding until you see the recovery mode screen.
3. When you see the option to Restore or Update, choose Restore.
   iTunes will download software for your device. If it takes more than 15 minutes, your device will exit recovery mode and you'll need to repeat steps 2 and 3.
4. Wait for the process to finish. Then you can set up and use your device.
