? if you have any info that would be great. I have remounted dev board I don’t know how to reflash a drive. if anyone could help if there is a semi easy solution i would love to know. Starts up, hear a ping sound when turns on but will not mount as an external disk when hook up to pc so cannot re install os or new firm ware. any way around this? Original op-1 not the field.
Thanks!
i am starting it in t boot mode as well just so known running windows 11
Normally you hold COM and turn it on I believe, then press one for update mode. It then mounts as a disk. Pretty sure that’s it but check manual.
So you do need the buttons and screen connected.
I have read every single thing available on a fix but i am getting nowhere. Holding com and turning it on is starting it in t-boot. Trust me if it was just that i would have remedied it already. 
”check the manual” good grief!
i’m sure you tried different cables, what about another computer (or a VM) with Win10?
Just guessing here,

USB2 vs USB3?
That’s what made the difference to be able to flash my phone. Just guessing too but in case, better to say than not.
