This paid software actually saved me from boot looping, despite it looks scammy.
Detailed steps:
1. Purchase "1 Year iMFC function Activation", follow the instruction from the product page to activate your account
2. Follow the instruction from here: [

3. If the first flash resulted in an Apple logo with a \~1% progress bar under it that stucks for a long time, force reset and enter recovery mode and flash again. Mine work in the second flash
4. You should see the iOS being flashed and after it, your phone should boot with white background and prompting for data recovery. It's ok to unplug now. Things should be OK til this point, just wait for it recover all the data and the long-missed homescreen should appear after that.

My story:
My iPhone 11 running iOS 14.x was bricked few days ago, right after I purchased a new iPhone 13 pro and attempting to transfer from the old to new. I got like 13xGB of photos and videos, and since I adopted a kitten in June, a huge chunk of them are pictures of it growing from a kitten to a cat.
Tried leaving it to boot for two days, it had booted successfully once but I haven't read the solution in this post so I just tried to delete some app and it became dead again.
Tried to flash new iOS via Finder and 3uTools as suggested in [
https://forums.macrumors.com/thread...-related-error-14-on-iphone-x-256gb.2292829/), gets error 1110.
Tried even buying Reiboot as they claim to fix the full storage boot loop issue but that just flashes a new iOS like any other free tools, and obviously didn't work.
In the Mac Rumours post I saw a comment that claims to solve error 1110. I wasn't down to that originally as I've already scammed by Reiboot. But after some thoughts on the bed, I noticed that they're the first saying being able to solve error 1110 (which is newly introduced in iOS 15). I decided to get up and give it a shot.
Despite it costs $80 and they host their software in Google Drive, and Google Drive even alerts me for virus found in their software, I still paid and downloaded as I was so desperate and I’m using Bootcamp anyways so worst case I’ll just wipe that partition.
The first flash left me with an error

and an Apple logo on my iPhone and a \~1% progress bar under it that doesn't seem to move.

Since I'm from Hong Kong and I can speak Mandarin, I just called them to see if I should wait or what (or that I fell into another scam). They answered the phone after two beeps and told me if I can't exit recovery mode with their toolbox, simply hard-reboot, enter recovery mode again and flash again.
The iOS was flashed successfully on the second try, I was prompted with this screen on my iPhone
[
And the rest is straightforward: Wait for data recovery til it reboots into normal lock screen, delete some apps to free \~10GBs and transfer to my new phone.
Hope this helps someone with their precious data!
