HTC One M8 Frozen at Splash Screen

[frozenandroid]

I have an older HTC One M8 that was very low on storage space. I restarted it, and while it was booting up, I decided instead to just turn it off after I saw the unlock screen. Since then, any time I try to turn on the phone, it’s frozen at the HTC splash screen.

1. Is there a way to recover without a factory reset? I’ve tried wiping the cache partition and rebooting

2. Is there a way to recover my data/pictures? I’ve tried using Android File Transfer but it complains that there’s no phone connected. Is there a way to recover files without turning the phone on? i.e., treating the phone as a storage device and recovering the files

3. If the above options are not possible, can I still recover my data/pictures after a factory reset?

Welcome to Android Central! Try charging the phone on a wall outlet undisturbed for at least 6 hours, and then power on again.

Hi, welcome to AC!
Either try factory reset or flashing the stock firmware but at this point your not going save any data , in future should consider cloud back up or different method especially important stuff.
