Iphone is disabled Itunes not compatible with my OS cannot reset phone

If you have a forgotten/unknown device passcode, or have a disabled device, unfortunately you have no option but to erase the device. However, you can eventually restore the data and settings from a backup you made before the device was disabled. You must have a computer to use the method below. If you don't have a computer, borrow one from a friend, or go to an Apple Retail Store or Apple Authorized Service Provider. You can also use a PC with iTunes. You will likely also need your Apple ID and password. All Apple mobile devices follow the same general procedure but the link below and other links off it provide model-specific instructions:

Here is a related video which to me has more complete and clearer instructions: https://www.youtube.com/watch?v=7s8-zLG9ySQ

Steps:

1. With the device disconnected from a computer use the model-specific instructions in the links above to shut down the device.

2. Connect it to a computer with Finder or iTunes (Mojave or earlier, or PC).

3. Restart into recovery mode (black screen with a cable indicating attach to computer).

4. When prompted, click "Restore" to erase data & settings, and update system software. May take some time.

5. Set up your device ( https://support.apple.com/kb/HT202033 ). Partway through you are offered the opportunity to restore your data and settings from a backup, or you can do this at a later stage ( https://support.apple.com/HT204184 ). Even if you have no backup, if you were using some iCloud services to sync items such as Contacts or Photos those may reappear once you sign back into your iCloud account --> Set up iCloud on your iPhone, iPad, or iPod touch - https://support.apple.com/HT208681

FYI .... iTunes software is written by Apple.

See if there is an iTunes update available.

Click your Apple menu icon top left your screen then click About This Mac then select the Overview tab then click: Software Update.

You are not getting the device into Recovery Mode. Hold down the buttons long enough.

Apple stopped using iTunes several years ago. Now you use Finder. If you are using old equipment it would help if you specifically said that.

My phone states the time and that my phone is locked. This page stated that I should hold down the two side buttons which I did....the phone called 911 and the operator answered...What else can I do with this phone?

I can't use my Iphone...
