So I’ve had my A1 for a few weeks now but i have to stick to firmware 1.02xxxx if I update to the latest 1.03.01 soon as the printer restarts I get a “low temperature mode” warning along the top of the little screen in red and it locks me out from printing anything.
Soon as I roll back to 1.02.02 it works fine, just wondering if anyone else has this problem or knows how to fix it and get my printer upto date
Thanks in advance Andy
Seriously? Nobody has this problem or knows whats going on ?
Have you tried doing a factory reset of the printer after updating the firmware? That and a power cycle often seem to clear up weird issues.
Yeah, it’s basically the only thing I could think of doing, I’ll try it all again tonight, thanks for replying.
No temp errors, but I’ve noted the filament edit menu has changed with the TPU95 disappearing from the bambu section.
I’d revert, but the prior version has no provision to select a nozzle size in the maintenence section.
This regards the mini, not regular
Also, I have started getting times where the touchscreen is unresponsive after turn on, flicking the SD in and out brings it on
I started getting Z Homing Failure messages… and rolling back seemed to fix this. So,…
I forgot to post the solution
I got in touch with Bambu and they sent me a new main board, I changed it and updated and the problem is now gone. 
I just now need therapy to stop printing constantly, I swear I’ve got an addiction
