[Samsung Galaxy A32 5G] GalaxyA325G:
Here is how to download firmware using SAMFW & how to flash with Odin. (make sure you get the right odin!)

WARNING: Everything below is a work in progress for the step-by-step tested procedure to download the firmware for the T-Mobile USA Samsung Galaxy A32 5G using Windows 10 as shown below.

Determine the name, model, and baseband version

Settings > About phone > Model name Galaxy A32 5G, Model number SM-A326U

Settings > About phone > Software information > Baseband version = A326USQS8BVJ1

With that information, get the latest Samsung firmware

Frija is one way to download the latest Samsung firmware

But my first test was with https://samfw.com/

In the SamFW web page on Windows 10, enter the device name or model code = SM-A326U / Galaxy A32 5G

That brings you to here which has hundreds of files, many with the designation "A326USQS8BVJ1" and some for Android 12.

https://samfw.com/firmware/SM-A326U

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:

Build Date = 20221012183750

That process of creating the firmware took me an hour and perhaps a bit more as it automatically generated a "A326U_AIO_A326USQS8BVJ1_fac.zip" file of 5.83GB size which I then had to manually download when it was finally 100% finished, creating.

Name: Samfw.com_SM-A326U_AIO_A326USQS8BVJ1_fac.zip

Size: 6259616116 bytes (5969 MiB)

SHA256: 89B5CF61033173BAFABBF7E7980F7FE1F8F43D88AD99C82729A4643884E5045B

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.

Note that nowadays, the CSC contains the Partition Information Table file (PIT) in most cases, but you might have a PIT file if not.

Also note the difference between the CSC and the HOME_CSC where you can only burn one, not both.

CSC = Updates the firmware using the PIT which means it wipes the device entirely and reformats the super partition containing everything from /boot, /system and /vendor

HOME CSC = updates the firmware but without the PIT file so that it does NOT wipe the device

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 with its associated ini file in the same directory to make sure it 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). OK. I think I got it. See Odin file upload steps below.

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 (the CSC and HOME_CSC being different in that the home version is said to not wipe user data).

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 HOME_CSC_OYN_A326UOYN8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5 or CSC_OYN_A326UOYN8BVJ1_CL24355525_QB57258298_REV00_user_low_ship_MULTI_CERT.tar.md5 (the difference is said to be the HOME version doesn't wipe user data clean).

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 where the "home_csc" is said to not wipe userdata but the "csc" will wipe user data.

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.

Please improve if/when you test this out as I only ran up to the last steps but I did not actually install the firmware.
