That's the issue most ppl are having, they are not putting the fastboot.exe inside the payload_output folder, I've helped 2 ppl flash over so far and that step is critical. They've also told me the windows script in OP does not work to flash, I've provided them with the script I created and it's worked for them.
[OnePlus 8T Guides, News, & Discussion] craznazn:
Seems like the problem is Windows paths are not setup and fastboot wasn't installed properly. In Linux, fastboot could be put in /usr/bin, /usr/local/bin, or anywhere else that's by default in the linux path. In windows, the default path is like C:\Windows\System32, which is not somewhere I suggest installing fastboot.

This is an issue in fastboot installation, and this is not a guide on how to setup platform tools. You can kinda bypass it by having fastboot.exe in the same folder as the .img, but that's not really the proper way to have fastboot installed on your computer. The scripts I had before, and even the scripts in the zip now, assumes the user has fastboot properly installed.

Anyways, I added a troubleshooting section and maybe that'll help some
[OnePlus 8T Guides, News, & Discussion] awr128:
Yeah, but ya need to make it as easy as possible for the average users.
[OnePlus 8T Guides, News, & Discussion] jwarrior319:
I mean, root and firmware conversion let alone anything with fastboot and adb arent really meant for the "average" user. Its always suggested to do your research first and make sure your ok with royally forking up your device if you do even one step wrong.
[OnePlus 8T Guides, News, & Discussion] awr128:
It's definitely not, but here we are
[OnePlus 8T Guides, News, & Discussion] jwarrior319:
I know i started doing this stuff without much knowledge but understood what could happen and was willing to take the risk. I also didnt expect anyone to fix what i forked up. This forum has a convenient search function people seem to forget about. Thats always the first place to start and if you cant easily find the answer doing that then ask.
[OnePlus 8T Guides, News, & Discussion] awr128:
There's definitely risk, I've probably soft bricked my 8T a good 5 times at least and a couple times where I wasn't even sure I could get to MSM back to TMO firmware.

I've been messing with a supposed Global/NA build and unpacking it's super.img trying to get it flash
[OnePlus 8T Guides, News, & Discussion] zeusofyork:
What they should do is create a directory in they C folder e.g

C:/platform-tools

And copy all platform tools into it. Take all the extracted files from payload dump and copy them there.

In cmd prompt

cd c:/platform-tools

Flash-all.bat

Works like a charm
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
Flash-all.bat is inside the unzipped conversation file or I don't unzip it?
[OnePlus 8T Guides, News, & Discussion] smallsmx301:
Hopefully you can get something to work.
[OnePlus 8T Guides, News, & Discussion] awr128:
Flash-all should already be in the folder with all the .img
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
It is, but in the OP it says not to unzip, is it so?
[OnePlus 8T Guides, News, & Discussion] craznazn:
where does the op say this?
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
"Execute "flash_all.bat" for Windows, or "flash_all.sh" for Linux, from the unzipped directory from step 2 as cwd."

Or I miss understood?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Where in your quote does it say not to extract the zip file?
[OnePlus 8T Guides, News, & Discussion] awr128:
I think you misunderstood.
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
Makes more sense if I misunderstood
[OnePlus 8T Guides, News, & Discussion] awr128:
No worries, it happens
[OnePlus 8T Guides, News, & Discussion] wahookasan:
If you run it from the zip file, it will unzip necessary files to a temp folder and run it from there, hence not being able to find your flashables

Does anyone have the modem.img from the tmo version? Id like to flash it to the eu build after conversion.
[OnePlus 8T Guides, News, & Discussion] badpanda:

[OnePlus 8T Guides, News, & Discussion] bigdog1459:
Not trying to say anything but is it needed? I thought the EU rom had all the necessary stuff. I know I still get 5g on mine and signal seems the same. I just want to make sure I didn't miss anything.

Incremental?
[OnePlus 8T Guides, News, & Discussion] awr128:
Incremental failed, so it dl the full 2gb uodate
[OnePlus 8T Guides, News, & Discussion] badpanda:
Even after locking your bootloader? Did you take it actual ota or via oxygen updater?
[OnePlus 8T Guides, News, & Discussion] awr128:
After locking the bootloader, it was the through the system update, not oxygen updater.
[OnePlus 8T Guides, News, & Discussion] badpanda:
Thank you [MENTION=10363437]awr128[/MENTION] for helping me convert to the EU successfully, for the patience and the extra files he provided me.

I don't know why but I read OP many times followed instructions and tried around 10 times manual and the new flash all output zip file and nothing worked I always ended up with a bricked device and had to convert back to tmo.

But [MENTION=10363437]awr128[/MENTION] helped all the way through.. just wanted to give him credit on this.

Thanks dude!

---------- Post added at 06:12 PM ---------- Previous post was at 06:00 PM ----------

Also I noticed how small incremental updates do not work at all via ota in system, failing at 97% and at 0% after.

Only full zip OS files can be use to update and not with official ota, has to be I'm guessing with oxygen updater or unlocking bootloader again to trigger ota to download full zips.

Rendering this in my opinion as not a full 100% pledged conversion as of yet as if you buy it from oneplus.

For people like me that all we care is to have the updates or being able to just update over ota with small incremental updates it could be a bummer... For people that care about rooting and magisk and of that stuff then this way might be ideal... Just giving my opinion.
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
People said in the past that OTA worked for them, what changed?
[OnePlus 8T Guides, News, & Discussion] badpanda:
It doesn't work. Only full zip of OS that can be almost 3GB or sometimes more if you have unlocked bootloader you can take only full zips ota, otherwise if you lock your bootloader after taking first full zip ota and then try to update ota it will fail and this point either don't lock bootloader or if locked then you have to rely exclusively with oxygen updater going forward no more ota.
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
Incremental works if the bootloader stays Unlocked?
[OnePlus 8T Guides, News, & Discussion] badpanda:
No. If you have your bootloader unlocked ota will still work as the unlocked bootloader will force or trigger a full os zip via ota. At this time this conversion will not be able to update incremental via ota doesn't matter if your bootloader is locked.

---------- Post added at 08:06 PM ---------- Previous post was at 07:18 PM ----------

I'm wondering myself how come incremental updates fails and won't work even after locking bootloader... Scratching my head on that.
[OnePlus 8T Guides, News, & Discussion] smallsmx301:
Submitted for my token today. Had to knock some rust off using adb but it came back quick. Hope we get a full global ota and a working msm before next week
[OnePlus 8T Guides, News, & Discussion] badpanda:
Highly unlikely unfortunately, msm conversion tool even more less likely and global full rom is probably never going to happen.
[OnePlus 8T Guides, News, & Discussion] jwarrior319:
The tmo firmware got better speeds in my experience and as mentioned previously by others. Flashing the modem.img from tmo should restore the optimizations
[OnePlus 8T Guides, News, & Discussion] smallsmx301:
Oh. Why is that? So we're going to be stuck with the EU ROM? Pretty sure I was on the India ROM on my 7 pro and everything was fine. Don't we have some weird issues though with the EU ?
[OnePlus 8T Guides, News, & Discussion] Shooter7889:
You have to go into settings on oxy updater and change to advanced mode so u can pick whichever device u want to see updates for. And u need to dl activity launcher so u can manually launch local updrade after downloading the ota zip up want to direct install. Good luck
[OnePlus 8T Guides, News, & Discussion] cammykool:
i cant find it in activity launcher
[OnePlus 8T Guides, News, & Discussion] Shooter7889:
It shld show up close to the bottom as system update
[OnePlus 8T Guides, News, & Discussion] awr128:
Wouldn't you just run it under the local upgrade once it's downloaded
[OnePlus 8T Guides, News, & Discussion] cammykool:
we dont have it
[OnePlus 8T Guides, News, & Discussion] craznazn:
The stock Tmo rom does not have a local upgrade option. They are trying to find it via Activity Launcher, which should work too and it sounds easier than my method in the OP
[OnePlus 8T Guides, News, & Discussion] cammykool:
do we know what the activity name is?

---------- Post added at 12:15 PM ---------- Previous post was at 12:14 PM ----------

what about flashing it from recovery?
[OnePlus 8T Guides, News, & Discussion] craznazn:
I don't know the name, I would've done that if I thought of it before the payload and fastboot flashing method.

I doubt it'll work from recovery since the signing keys should be different. Wouldn't hurt to try. Actually I don't even know if the recovery gives you an option to install a zip
[OnePlus 8T Guides, News, & Discussion] cammykool:
would i just name it nupdate.zip and dump it on the root of storage?
[OnePlus 8T Guides, News, & Discussion] craznazn:
are you using python3, pip3, and venv?
[OnePlus 8T Guides, News, & Discussion] cammykool:
Found the APK and sideloaded it. It won't work. Pushing upgrade just does nothing. So it's hard removed.
[OnePlus 8T Guides, News, & Discussion] cammykool:
Yeah. I actually thi k I just figured that part of it out. It seems it won't work on Windows.

[OnePlus 8T Guides, News, & Discussion] jwarrior319:
No, im the one asking for it.
[OnePlus 8T Guides, News, & Discussion] androidbuff123:
Not sure if anyone else has experienced this but after converting a US TMO device to the EU version, I am not abe to get the TMO sim to be registered. Mind you I did this while traveling and I'm in a foreign country because I had to wait 7 days to get the unlock token from oneplus. I'm in India now where TMO partners with local carriers. The same sim worked just fine in the US (before the conversion) but now after conversion I get "SIM 1 not allowed". The notification is from Phone Services.

Luckily I also havey iphone 12 pro and it works just fine when I put the sim inside that one.

Anyone know what could be causing this on the 8T and how I can possibly fix this?

I am willing to try flashing TMO modem but I can't seem to find one and somewhere else I read that it doesn't really matter because the bands are flashed in the NAND.

Thanks
[OnePlus 8T Guides, News, & Discussion] craznazn:
For what it's worth, both EU and TMO connected to n41 at my house and had similar speed.

You can try MSM back to stock on Tmo for now and seeing if your SIM still works. If so, you can then extract Tmo modem before flashing back. You might also try the India ROM
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
I see reports here from today that you can't take incremental OTA after conversion but if I remember correctly in the past some said they were able to take successful the OTA can you confirm if OTA works or if it doesn't work? I see no mention about OTA after conversion in the OP so I am asking
[OnePlus 8T Guides, News, & Discussion] craznazn:
Full OTAs definitely work. I have not tried incremental, since I root by default that's not even an option.
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
Yeah, they said that only full works and incremental fails midway or at 97% and the only way to install incremental is via oxygen updater

Looks like the link to the Tmo imgs are dead. I have an idea to see if I can fix fingerprints, but need a copy of the modem.img

And yes, you will need to reflash each OTA because the OTA includes an EU version of modem.img, if you want to use the Tmo version.

I would like some data behind the Tmo modem vs the EU firmware in terms of tower connection, battery consumption, speed, etc, if you can provide it.
[OnePlus 8T Guides, News, & Discussion] sameog:
When I flashed the non-hlos.bin, my data speed picked up. EU build, in my assessment, is kind of slow. It could very well be that hardware/software conflict.

I've been trying to pull the tmobile modem.img but my adb skills suck. Fastboot, for me, is easy, provided J have the command I need to use it.
