[Solved] Flashing new bootrom fails

I'm currently trying to swap over to the iceman distro however when I try to flash the proxmark it finds it, but then the port changes from com5 to com6. It then says that it is offline and cannot flash. I'm trying to just flash the boot from, but it says I need to flash the boot rom to flash the bootrom. I'm out of ideas. Here's the output.

pm3 ~$ ./pm3-flash-bootrom
[=] Waiting for Proxmark3 to appear...
[=] Session log C:\Users\Nick\Desktop\ProxSpace-master\pm3/.proxmark3/logs/log_20200918.txt

[!!] Error: Proxmark3 not found.

Have a nice day!
pm3 ~$

I've tried uninstalling all hidden com ports a few times and am out of ideas. I've rebuilt and have the relevant platform for my proxmark. Any advice would be great.
Thanks.

Re: [Solved] Flashing new bootrom fails

Try the button-trick and enter the bootloader before running the flash command.

- unplug pm3
- press and keep button pressed.
- plug in pm3
- led A, C should now be lit

here it diverges,   depending on which fw you had on before.
If you are on the rrg/iceman before, you can now let go of the button and run the command.

if you are on official before, you must keep on pressing the button and run the command,  and afterwards you can let go.

Re: [Solved] Flashing new bootrom fails

I forgot to mention I'd done that. Ran it again as you mentioned for the iceman version, and got this result

Re: [Solved] Flashing new bootrom fails

looks like you seem to have usb / serial problems.
UART error while setting com state

Are you running on virtual machine?  Their usb can be dodgy,  or check your usb cable,   or swap usb ports.

Re: [Solved] Flashing new bootrom fails

Gave that a go. I'm using windows and proxspace. Swapped the port and cable. No luck.
The com port swap, which is odd, then doesn't come back till after the minute timeout. I also used another boot loader which didn't have the timeout, which gave the same result

Re: [Solved] Flashing new bootrom fails

It looks like you are running mixed client/fw versions from different repos. 
The recommendation is don't do that.

Re: [Solved] Flashing new bootrom fails

I am trying to avoid it, but the full image won't flash. I either get the uart error, or an offline error and timeout. Could it be the hardware?

Here's a screenshot to hopefully help explain my problem

Re: [Solved] Flashing new bootrom fails

Alright, after pulling all of my hair out I've got it.
I saw somewhere online someone having a similar problem with arduinos. Easy fix was to just flash it on another computer. It seems like something isn't happy with the way my computer assigns COM ports or something of the like.
Thank you for your help, I'll try change to solved now.
