[Android Software Development] fallen_jedi:
First off thank you OP for modifying the ODIN software. Sorry that I am n00b and failed at using your modified version.

Several years back I used ODIN Prince Comsy to get my Samsung Galaxy S7 from the SM-G930V (Verizon) to the SM-G930U (Unlock) version.

It worked fine and the process was straight forward. I did this so that I could use Moblie Hotspot on the phone as I have a grandfathered plan for unlimited data.

This week I got a Samsung Galaxy S8 and wanted to do the same thing.

To have firmware that is not from Verizon so again I could use the Moblie Hotspot feature.

My S8 showed the following:

Model: SM-G950U

Android 8

Samsung Experience 9

Baseband: G950USQS5CSB1

Kernel: 4.4.78

Build: R16NW.G950USQS5CSB1

SE for Android Status: ENFORCING

Knox: 3.0 (API level 24)

Android Security: 01/01/2019

(Did the phone have Bootloader1 at this time?; fresh out of the box)

In reading these forums I looked for firmware G950U1 designation.

I downloaded the original ODIN and this firmware

VZW-G950U1UES5DSF3_G950U1OYM5DSF3-20190614

ODIN failed it gave me the RED FAIL box at the top.

I looked for my prior notes and saw ODIN Prince Comsy so I download that version and tried the file again.

Again ODIN failed it gave me the RED FAIL box at the top.

So I figured I had the wrong firmware version and continued looking.

Download this version

G950U1UEU1AQG2_G950U1OYM1AQG2_VZW_4file

and at the same time cam upon this tread so downloaded Odin3_v3.13.1_3B_PatcheD.

I started up Odin3B (but failed to run it in ADMIN MODE). My 1st mistake :(

I loaded up the files and under the options checked off AUTO REBOOT and F. RESET TIME.

Odin3B ran and I got the green progress bar at the top left. I was excited because I figured this would finally work.

So I leave the computer running and go get a snack. When I come back the RED FAIL box is at the top. SIGH.

However the S8 has a blue screen saying.

Software Update Failed

Your device didn't update successfully. Use the Verizon Software Upgrade Assistant on a computer to repair your device and complete the update.

I try to power down the phone and nothing.

I try to go back to download mode sort of nothing.

Meaning when I use POWER + BIXY + VOLUME DOWN I get to the screen before download where you have to use VOLUME UP to get into download mode. If I use VOLUME UP I get the blue screen of "Software Update Failed".

So I panic and here is maybe my 2nd mistake. I go and find the Verizon Software Upgrade Assistant software, download it and have it run. It says it is a 30-90 min process and it begins to work. The progress bar goes all the way to 80% before the software gives me an error. Saying it can not complete the progress and if I want to retry or cancel. I re-try and the same issue occurs. At 80% it fails and this time the popup notice says to call Verizon. Yeah nope!

So I try to turn the phone off and it gives me a red text on the blue screen saying something like "Download stock firmware to phone". WOW even the phone knows what I need to do. :rolleyes:. In any case I go back to reading some more on how to resolve this issue. 1 day turns into 2, and 2 into 3. Too much reading and can't find anything similar to what I have done.

I do pick up 2 tips.

Run ODIN in ADMIN MODE.

Use the XAA carrier version instead of VERIZON for what I am trying to do.

So I download this firmware

XAA-G950U1UES5DSF3_G950U1OYM5DSF3-20190614

and start up ODIN3B (in ADMIN MODE)

the phone still shows the blue screen but in ODIN is shows <ID:0/003> Added!! so I figured ODIN must be seeing the phone.

I go into the options check off AUTO REBOOT, NAND ERASE, and F. RESET TIME.

I checked off NAND ERASE after reading all the pages on this post and who it was suggested for another user.

I run ODIN3B and seems to work, no green progress bar but no error either.

10 minutes pass and I get the bad news.

<ID:0/003> Odin engine v(ID:3.1301)..

<ID:0/003> File analysis..

<ID:0/003> Total Binary size: 5812 M

<ID:0/003> SetupConnection..

<ID:0/003> Complete(Write) operation failed.

<OSM> All threads completed. (succeed 0 / failed 1)

It did not work. So I went back through the thread to see if I missed anything else.

It talks about changing the port and cable. The cbale I have is brand new as it came with the phone.

So I change ports on the desktop first. ODIN sees the phone on COM4 vs COM3 like before.

Good sign I think and I go ahead and redo my steps to flash the XAA firmware.

It seeems to have failed but I am not getting a FAILED error.

ODIN3B seems frozen.

It's been going for 4hrs now and nothing.

Any ideas? I know someone paid $30 for a local shop to get their phone back up and running.

I'm about ready to go that route but feel that it can NOT be this hard. What have I overlooked?

Apart from being a loser as I have a bricked S8 right now. :crying:
