E (1486) spiram: SPI SRAM memory test fail

I have a LillyGo TTGO T-beam v1.1 that I bought from an Amazon seller (OneMoTime).

The device was working for about a day, when I noticed it was frozen. Upon reset, it would not boot.

I hooked it up tp my laptop and used the esphome-flasher to connect to the console log - and I see the following repeat over and over:

[21:04:11]Rebooting...

I was able to re-flash the firmware - even tried a few different versions - but had the same end result.

I am pretty sure this is a hardware defect - but wanted to check here in case I am wrong.
