Can you give me advice how ODIN mode might be able to help me?

My T-Mobile US Samsung Galaxy A32-5G SM-A326U is stuck in the black screen of death saying
  • "SAMSUNG Galaxy, Secured by Knox, Powered by Android"

    It will only go into that black screen of death mode, or into the light blue ODIN download mode.
Since I can't do anything with the black screen of death mode, can you let me know what the light blue odin mode will do for me?

The phone has had USB Debugging on ever since it was born, and adb debugging has been done since day one, but the PC won't recognize the phone over USB and the phone can't get onto the Wi-Fi network for adb to run over the air.

Download your firmware from samfw.com
Thanks for that advice to download the firmware for the T-Mobile USA Samsung Galaxy A32 5G, which I summarize the steps for others finding this as I stumbled along on Windows 10 as shown below.
  1. Determine the name, model, and baseband
    • Settings > About phone > Model name Galaxy A32 5G, Model number SM-A326U
    • Settings > About phone > Software information > Baseband version = A326USQS8BVJ1
  2. With that information, go to https://samfw.com/
    • Enter device name or model code = SM-A326U / Galaxy A32 5G
  3. That brings you to here which has hundreds of files, many with the designation "A326USQS8BVJ1" and some for Android 12.
I'm not sure which "A326USQS8BVJ1" "Android 12" file to pick next (is there any way to intelligently choose from the many that do exist)?

Most (if not all) are USA files, so I arbitrarily selected one of the "AIO" CSC (whatever that means) files and that brings up three files that are for Android 12, the latest being:
Download the firmware flash for Samsung Galaxy A32 5G with the code is SM-A326U. This firmware for the region with CSC code is AIO (AIO - United States). Please make sure the code is correct. You can check model code in Setting - About, in Download mode or you can find it by flipping your phone or among the things you found in the box. This product PDA version is A326USQS8BVJ1 and Android version is S(Android 12). This firmware size is 5.83 GB.

This firmware is official from Samsung Cloud Server. Of course, we recommend you are using official Samsung tool like Samsung Smart Switch or Samsung Kies. Samfw.com will not responsible for any damage caused by using the files on this website

  • ANDROID VERSION S(Android 12)
  • SIZE 5.83 GB Full Files
  • MD5 9019690daf609d85d21bbf6eccebb9b8
That process of creating the firmware takes at least an hour and perhaps a bit more as it automatically generates a "A326U_AIO_A326USQS8BVJ1_fac.zip" file of 5.83GB size which you then have to manually download when it's 100% finished, creating.
Name: Samfw.com_SM-A326U_AIO_A326USQS8BVJ1_fac.zip

Can someone advise me as to what's the next step?
OK. This seems to be the next set of steps.

1. Extract (unzip) that Samsung firmware zip archive.
AP_A326USQS8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT_meta_OS12.tar.md5 (6,331,637,961)

_FirmwareInfo_Samfw.com.txt (719)

2. Download the Windows Samsung Odin Tool 3.13.1
Name: Odin3_v3.13.1_3B_Patched_Samfw.com.rar
Size: 1080120 bytes (1054 KiB)
SHA256: 796DBCD0A2262228AF0492B69BCFF0555CDC9AFE422045BC295BB2ABF74FF107
3. Extract that Odin RAR file (I used 7zip).
Name: Odin3 v3.13.1_3B_Patched_Samfw.com.exe
Size: 3172864 bytes (3098 KiB)
SHA256: 1E84628BD5EF44EB6A00954A7DE5445375C953879F889EF82CB73DB0358CEEAF
4. Run that unpacked executable file on Windows which brings up the Odin GUI which makes no sense to a noob like me. (Need to add more here since this is a critical step in the process which has no good instructions yet).
5. Put the Samsung A32-5G into "Download Mode" by holding volume up, volume down, and power and then right away plug in the USB cable from the computer port such that all four are done simultaneously.

Immediately this puts the phone screen blue which is apparently Download Mode (aka Odin Mode) which will say...
  • Warning A custom OS can cause critical problems in phone and installed applications.
  • If you want to download a custom OS, press the volume up key.
  • Otherwise press the volume down key to cancel
    • Volume up = Continue
    • Volume down = Cancel (reset phone)
    • Side key = Show Barcode {IMEI, SN, Device ID}
6. In the Odin tool on Windows 10, you have two use models, the first of which is to add the five BL, AP, CP, CSC, and USERDATA files separately, or together as one HOME_CSC file.

I don't know where to load the HOME_CSC file so I'll load the five BL, AP, CP, CSC & USERDATA files separately into the Windows Odin GUI.

In Windows Odin, click the BL button and navigate to the file named BL_A326USQS8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5 file.

In Windows Odin, click the AP button and navigate to the file named AP_A326USQS8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT_meta_OS12.tar.md5 (notice this will take a while as this is the largest file).

In Windows Odin, click the CP button and navigate to the file named CP_A326USQS8BVJ1_CP23036338_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5

In Windows Odin, click the CSC button and navigate to the file named CSC_OYN_A326UOYN8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5

In Windows Odin, click the USERDATA button and navigate to the file named USERDATA_AIO_A326USQS8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5

7. Make sure re-partition is NOT ticked in the Windows 10 Odin GUI "Options" tab which has the following settings by default
[x] Auto Reboot
[_] Nand Erase
[_] Re-Partition
[x] F. Reset Time
[_] DeviceInfo (mine is grayed out)
[_] Flash Lock

8. In the Windows 10 Odin GUI, with the phone connected to the Windows 10 PC in blue Download Mode (aka Odin Mode), now click the Odin GUI START button to begin reflashing.
