1 of 4 t-beams will no longer update

Cool. Btw it is okay for the Android screen to go to sleep during the update. The update is performed by a background service.

“Brute force” method of installing/updating TTGO T-Beam firmware is explained there.

This low cost (3-4USD) method can help when a particular board has microUSB (D+/D-) and/or ESP32 GPIO0 related issues.
