You'll need to start over with first using Odin to flash an Android 10 firmware package. Note that there is no going back once you do this.
Then follow the posts in the twrp thread to reach a rooted stock Android 10 setup.
If you're having issues with Odin connecting, you'll need to double check your drivers, cables, ports, or possibly even a different PC.

Hi,
Thnx for your reply!! my problem is that i cant flash anything with odin:
<ID:0/009> Odin engine v(ID:3.1401)..
<ID:0/009> File analysis..
<ID:0/009> Total Binary size: 35 M
<ID:0/009> SetupConnection..
<OSM> All threads completed. (succeed 0 / failed 1)
<ID:0/009> Odin engine v(ID:3.1401)..
<ID:0/009> File analysis..
<ID:0/009> Total Binary size: 35 M
<ID:0/009> SetupConnection..
<ID:0/009> Initialzation..
Tried 3 diffrent ROMS, and tried flashing only TWRP again but cant. i dont know if my bootloader locked and cant run de CROM service, since i cant run android.
i never got to Android 10 working, i am downloading 2 more stock roms (andoid 8) to see if odin flashes them, I tried reseting download moda and start odin as fast as i could (i read that this fixed odin issue somtimes) but with no good result on my side, tried like 30 times, all the USB on my pc, and 2 difrent cables.

When Odin says it failed, what did your device show? It should show an error or something. I think it would be in red lettering.

That firmware is extremely old. You probably should at least try with one of the first versions that are Android 10. Also, if you don't have the Samsung Dex desktop app, install that as well. It should help resolve some driver issues if that is causing problems.

I have the following andoid 10 Roms:
G9650ZHU6DTA7 - debloted - https://forum.xda-developers.com/galaxy-s9-plus/how-to/snapdragon-s9-sm-g9650-android-10-t4048625
G9650ZHS6DTB4 - https://sfirmware.com/downloads-file/135138/SM-G9650_2_20200229043228_tal4inqtnt_fac
In both having the same problem as shown previously, have delted and reinstalled Samsung drivers (Samsung_USB_Driver_v1.7.23.0) and restart PC.
Also downloades Dex, does not recognize any device. Odin still not working.

Man I don't know to be honest. I just upgraded from February patch 10 to April patch myself. Didn't have any issues. You can't go back to Oreo though. You're only able to use Android 10 now due to rollback protection.
If you can, I would try a different computer or even possibly a virtual machine with Windows 10 or windows 7 on it.

I've been on this issue for a few weeks now trying to see if I can fix it. As of right now I have the same issue. So we'll see. Most say use a hub or another PC and it works. So does on mine. So yea I could. But screw that where's the fun. Let me do some more tests. Because I've tried everything from driver enforcement to bios settings. Drivers and more. And still no go. I can also add upon reboot I get a last USB connected was not recognized. And have to reboot download mode. So I do believe the pc is trying to talk to the device just not fully opening the com\serial port

I am trying to get fastboot runing, but nothing, only bootloop or download mode, tried reintalling drivers, difrent roms, reseting download mode, canceling download mode.
nothing working so far.
i suspect that USB debbuging locked itself and does not let me flash with odin

fastboot isn't available for Samsung devices and USB debugging wont lock you out of going to download mode or recovery.

Thanks, so i wount try anymore with fastboot or ADB,
i will try on a MAC pc i have and Jodin 3. will come back with any news.
on the other hand, afer installing all dirvers i could find online, my device manager shows the phone as "samsung mobile cdc composite device" and shows as working properly. Odin recognizes the phone, but still can flash anything.

Yea it will eventually fail and show that it could not open the com or serial port same here. It's most definitely a windows issue. If we can get known users to chime in when there device is connected in download mode to show me what their devices show in device manager.
Mine shows as Samsung composite USB. And a Samsung modem as well. I've been messing with the modem shown. If you disable that or mess with it while in download mode it won't show added or detected. So I'm thinking it's in that modem driver and not the composite

MAC not working, Heimdall could not get my PIT file, and tried using the one inside de CSC and same result, PIT corrupted.
So back to my PC and trying to get the drivers to work.
How should i see my device on device manager? Samsung s9650? Andoid phone? Samsng modem?
