Flashed. Sorry should have specified.
I would have stayed on the original but in preparation for flashed card, I converted over to opencore and lost my Windows drive trying to covert from legacy to EFI. I attempted to fix with no success and didn't want to go through the hassle of installing windows (which was another nightmare 2 mos ago!). maybe I should reconsider for now.
at this point just trying to get system stable enough to use.
UPDATE: I found that my system is not booting into any OS as of this morning. I removed TB card, performed NVRAM reset with same issues. I suspect I'm dealing with other hardware related issues at this point and have removed all other posts and files related to flashed TB troubleshooting.
sorry for the confusion...

I am getting write operation failed error when I try to write on the blue chip using CH341A. I am able to read both the chips though.
Well if you erase it but can’t write it you’re in a real pickle.
Ha! Yes you are.
I should have clarified. Mine had the same trouble and worked after I did that. So, at your own risk I suppose!
Reseating the connection and replugging the flasher into the USB port helped too.
Did you do a boot rom dump before you started your EFI install? what graphics card are you using? I was using Nvidia gtx680 and couldn't install windows. I finally downloaded a 2015 version, then updated the Nvidia drivers and then windows and it worked. There is a way to convert LEGACY to EFI without deleting your windows and losing your files. I'll pm you so we don't stray off topic
I am using PC software CH341A. I tried erasing the chip and programming the new Rom still getting the same Write error.
Anyone figure out how to plug MacBook pro into Mac Pro through thunderbolt ?
Do you have your eeprom at 3.3v there is a tutorial a couple pages back

Thanks for the reply. I don’t think I backed up boot rom properly for windows, only Mac. I have an rx580 and doesn’t appear to be any issues with graphics. I ran mbr2gpt using 3rd utility but was preoccupied with TB troubleshooting so probably wasn’t paying attention and messed up.
if you can pm procedure that would be awesome!
If you've got your thunderbolt ironed out then you should be able to create a Thunderbolt Bridge in your Network Settings.
update: I added Tbtforcepower.efi to drivers folder and as well as added to config.plist. Unfortunately no change, still 2x boot. Your post on the other forum mentions an additional tbreset Kext and SSDT. Are these req’d as well?
Those won't be useful here. Tbtforcepower was a shot in the dark and turns out doesn't apply when you've got a flashed card. It doesn't have much business here but was genuinely curious. So thanks for trying it!
I'm gonna sit this one out until my own Mac Pro and GC arrives and do less clogging up on these forums
I have 4,1>5,1 as well and currently have to boot 2x's for TB drivers to load properly with "flashed" TR.
If using DSM2 EFI folder, I found I had to cold boot w/ option key, select Mojave, then warm restart back into Mojave to establish connection.
For now, I'm using Nico's EFI folder (colleague of DSM2) with a slightly modified SSDT (downloaded from tonymac) to where I corrected ACPI path to match my system. It's still requires 2x boot but without option key and works with both Mojave and Catalina.
I've attached if you want to test on your system. Let me know if it works for you...
this not change the Game because the Firmware do the Job.If you don`t use OC you have the same result.
with your SSDT you have the same as you don`t have installed OC.this SSDT not work.
On PCI you don`t have Intel Thunderbolt.You have Unknow.
With Nico`s SSDT you have Intel Thunderbolt and i think is more funktional as your moded SSDT.
Yes it freez if you start without Option Key.But after Restart it works.
And this is the point to fix. Boot only one time...this is the challange.
Thanks for the reply. I agree that this is not a game changer, this is not my intention. I’ll be the first to admit I am no expert on any of this. 1x boot is definitely the goal at this point.
I appreciate your validation with option key on first boot with nico’s SSDT. Until now, no one else has “chimed” in so I thought it was isolated to my system. Also good to know my SSDT didn’t work for you. maybe my ACPI path is unique, again not an expert
I am by no means questioning the files provided by nico or DSM2. They are the experts and I appreciate their time and efforts. What I am concerned about is if 1x solution is provided (via OC boot), we will always be stuck with 2x boot if the option key is always involved.
2x boot with OC and a stable connection for my Apollo will suffice for now until further developments are released.
I think the real ask here is for one that doesn't require using an external programmer to do the flashing with a cable.
AFAIK the answer is "no" and you have to use external programmer, in which case flashrom is the go-to answer. Install brew then use brew to install flashrom.
So I've ordered this programmer that seems to have the option of 3.3 or 5v.

Good evening!
I just wanted to tell you that I am currently having massive health problems and I am on my way to the hospital.
I have had a high temperature for over 9 days and there is no real improvement in sight.
Will be back as soon as Possible...
