Regardless, you put yourself in this situation and as you've been told, the ONLY way out is to erase the phone with your computer and set it up again, which means you MUST be on iOS 26.2.1. There is no other alternative.

Whatever damage or data loss that might have been done has been done.

Erase the device with a factory reset, and restore iOS using a Mac or PC. (I’d not assume a local reset will work.)

Select Restore here: If you forgot your iPhone passcode or your iPhone is disabled - Apple Support

I know that I only have a choice of iOS 26.2.1, but the iPhone 11, starting with iOS 17, starts to work unsatisfactorily.

Did you follow the instructions that users have provided to you?

Nothing is going to improve until you erase the phone and restore it again using a Mac or PC. Do NOT restore any backups that were made when you had the bad software installed on your phone.

When you have restored the phone, check to see what shape the battery might be in as follows:

Tap Settings > Battery > Battery Health & Charging

Report on the reading that you see for Maximum Capacity

You have trashed your phone. At this point, this is all that you can do:

Erase the phone using a Mac or PC and Restore the phone to install the current iOS version.

Hello! I have an iPhone 11 on the iOS 16.6

I are a jailbroke it

Congratulations. You have forfeited all rights to support for your phone.

Put it in DFU mode and restore iOS using your computer. Do NOT restore from your backup.

However you do it, you have no choice over what iOS version you end up with. It will be the current one supported by the iPhone model you have.

Whether you might find somebody that can detangle your current corrupted install (and preferably without scams and malware), we cannot assist with that around here.

Reliably untangling a jailbreak means a DFU factory reset and a reset means iOS 26.2.1.

Options? Sell this iPhone 11 and get either a newer iPhone with a faster processor, or sell it and get a replacement device with better support for the sorts of changes and deep customizations you seek. Consider acquiring a PinePhone running Linux, for instance.
