Hi,  I'm new here   Could anybody advise.  I would really appreciate it. 
I have a Tinyscreen+ which seems to be stuck in Bootloader Mode.  I have a few Tinyscreens+ and have recently been trying to establish IR communication between them so I may have damaged it but I'm not sure.  I have tried to  load an empty sketch to unlock it and sometimes it does seem to unstick itself but then it flicks back into Bootloader Mode as soon as I try to load anything that tries to bring it back to life.  It there anyway of resetting it?
Please excuse my ignorance. I am an engineer but have not programmed for a while now 
Thanks.

PS when trying to upload I get "Locked" appearing in the error report.

PROBLEM CLEARED 😄. I think it was a coms port issue. I am using a usb hub. Once I restarted everything and plugged direct to motherboard it cleared.

Glad to hear you could sort it out!

It seems restarting everything usually seems to do the trick for most electronics
