are there anyway to unlock iphone 11promax but still keep the video and photos? i just forgot my phone's password..cannot believe that

If you sync your photos/videos with iCloud or you have been routinely backing up your iPhone, once you restore the phone from a forgotten passcode, your data can be brought back. If you don't sync with iCloud, nor have you been backing up your iPhone, then no, there is no way to restore your data as it will be wiped in the restore process.

If you used iCloud Photos on your phone, then the photos are viewable on your Mac and on iCloud.com. It sounds like this was not set to sync on your phone. If iCloud Photos was not set to Sync your Library on your phone, then the photos are stored in your backup file where you will be able to restore your photos when you set the device up again and restore from that backup. Of course, you would have to be using iCloud to backup your device or use the backup file if you backed it up to your computer.

To reset the Passcode on your device, it will require the phone to be deleted.

Nope. It's too late to buy more storage in iCloud for your photos to sync to the cloud. Making sure your data is safely stored is important before something goes wrong. You are going to lose your data.

Yes, that's what it means. By your own admission, you ran out of iCloud storage, so you weren't backing up to iCloud. Whatever you had in the last backup you made, however long ago that was, can be restored, but anything you had on your iPhone since the last backup will be lost.

You're welcome. Once you're past this unfortunate situation, buy more iCloud storage, so this can't happen again. You can go from the free 5GB plan to 50GB for about $1 per month. And make sure you write your new passcode down somewhere safe for future recall.
