[Q] Any hope for a stock recovery boot loop with a broken charging port? topic

I have an old Sprint S3 that I am using as my son's media player that I swap batteries to keep it going because of a broken charging port. It's usually in airplane mode but I connected to wifi and noticed there was a System update (L710VPUDNJ2). I accepted the update but after rebooting into stock recovery I got a system 7 error (I'm not sure what I did in the past that would cause a system 7).

I think it's possible to sideload this OTA update via ODIN but since the usb port is non functioning I can't try that. Factory reset did not get me out of the recovery boot loop. Not that I expected it, but applying the update via sdcard did not work either.

Any hope for this phone?
