VZW S6 to TMOBILE S6 - need stock ROM

I have the Samsung G S6 running Android 6.0.1 with Sec Patch level 9/1/2016.

It was purchased via Verizon Wireless and now I have moved the service over to T-Mobile,
Installed the sim... configured the APN.. etc.. it all works on tmobile's network and so forth.. However I an unable to perform any system updates.
I'm sure this has to do with the fact that it's a VZW rom and not a T-Mobile ROM.

I would like to flash this hardware to a t-mobile ROM... but before I do... I thought I would ask a few questions.

1. Has anyone ever flashed a ROM on the VZW carrier and moved it to another carrier.. IE, t-mobile on the S6?
2. If so, where can I obtain the STOCK rom for the S6 standard ROM for T-mobile's network?
3. What issues, if any, were encountered?
4. I have the t-mobile SIM and all is working accordingly but, I still get an alert on boot that the SIM is not a Verizon Wireless SIM.

Thanks in advance.
I did a quick search through the forums but I didn't find anything specific.

I don't have all the answers but

Yes I have flashed ROMs. But not that model or carrier.

2. If I was to go look I'd check out XDA Forums and XDA Developers as they had tools and ROMs aplenty both stock and others.

3. For my work the other issue was how complicated it was, had to have a few blank memory cards lying around. This is not an offer to duplicate the ROM install instructions at XDA.
4. Unsure what that sentence is about. There's no question and you lead that it works so take care when posting to ask a question and end it with a question mark.

reference to?

if you're referring to this..

4. I have the t-mobile SIM and all is working accordingly but, I still get an alert on boot that the SIM is not a Verizon Wireless SIM.

it states the issue that on boot the installed ROM that is a VZW ROM states that the SIM is not a VZW SIM. and yes... it does work, but obviously I would like for the error to go away.

I figure that would also be resolved with a TMOBILE ROM.

Glad it helped.

I read your post and didn't find a question but in the title. If I were to guess if a ROM will fix something, that's a carrier ROM so no, I can't tell you one way or another what will change.
