If you’ve been hitting Odin errors, someone has probably told you to “just use patched Odin.” It sounds like a magic fix. It isn’t, and in some cases it makes things worse.
In this guide, I will explain what patched Odin actually is, which errors it can and can’t get past, and what I’d do instead. I’ll also be upfront about where I stand, because I don’t host or link to any patched build on this site.
The short answer
Most people don’t need patched Odin. The errors it’s supposed to fix are almost always a sign that something is wrong with the firmware, and a patched tool just hides the warning.
Use the normal Odin3 v3.14.1, and make sure the firmware matches your exact model number. That solves most cases.
What is patched Odin?
A patched Odin is a copy of Odin3 that somebody edited so it skips some of its own safety checks. Samsung didn’t make it. An individual developer or a forum member changed the program and shared it.
The best known one is a thread called Patched Odin 3.13.1 on XDA Forums, and later builds of 3.13.3 and 3.14.1 exist too. Technastic lists a few of them by name, like “Odin3 3.14.1 3B PatcheD” and “Modded Odin 3.13.1 Raymond.”
Guides that describe them say the same thing. A patched build stops checking the model, the carrier and the SHA-256 hash of the firmware files before it flashes. A normal Odin checks all three and stops if something looks wrong.
Which errors does patched Odin get past?
This is the part most videos leave out. Not every Odin error comes from Odin. Some come from the phone, and no version of Odin can override the phone.
| Error | Who stops the flash | Does patched Odin help? |
|---|---|---|
| FAIL! Model mismatch fail | Odin | It skips the warning, but the firmware is still for the wrong phone |
| FAIL! SHA256 is invalid | Odin | It skips the warning, but the file is still damaged |
| md5 error! Binary is invalid | Odin | No. The file is corrupt, so download it again |
| FAIL! (Auth) | The phone | No |
| SW REV. CHECK FAIL | The phone | No |
| Only official released binaries are allowed to be flashed | The phone | No |
| Custom binary blocked by FRP lock | The phone | No |
| No ID:COM, Odin doesn’t see the phone | Driver or cable | No. Check the Samsung USB Driver and your cable |
Read the middle column again. When the phone refuses the file, patched Odin gets the same refusal. I go through every one of these messages in my Odin FAIL errors guide.
Why skipping the checks is a bad idea
The model check exists for a reason. If you flash firmware for a Galaxy S24 Ultra (SM-S928B) onto an SM-S928U, Odin warns you. With the check off, it just goes ahead.
Sometimes the phone rejects the wrong files and you lose nothing. Sometimes it accepts part of the flash first, and you end up with a phone that won’t boot. Fixing that usually means finding the right firmware and starting over, and on a bad day it needs a repair shop.
The hash check works the same way. It catches a download that broke halfway. Turning it off means a damaged file can get written to the phone.
Now the trust problem. Odin is closed source, and Samsung never officially released it. The Wikipedia article on Odin says the public copies are believed to be the result of leaks, and that none of the downloads are authorized by Samsung. A patched copy adds one more unknown, which is whoever edited it.
You can’t read the code to see what changed. All you have is the reputation of the person or site that gave it to you. Odin is a program you run on your own PC, so I wouldn’t run a copy from a file-sharing site.
Where I stand on this site
I don’t host patched Odin, and I don’t link to download pages for it. I only link to the XDA thread above so you can see what it is.
The builds I do host are the plain ones, with a SHA-256 you can check. I also have to be honest about one of them. The Odin3 v3.14.4 ZIP I host is disputed. Its main program has the same code as v3.14.1, and the ZIP adds an extra Microsoft networking library. I explain the details on the v3.14.4 page, and that’s why I recommend v3.14.1 instead.
What to do instead
If you were about to grab a patched build because of an error, try these first.
- Check your exact model number in Settings > About phone. It looks like SM-S928B.
- Download firmware for that exact model and region. SamUpdater shows the latest build for each one.
- Look at the bootloader digit in the build number. It’s the fifth character from the end, and it must be the same as or higher than the one on your phone.
- Re-download the firmware if you got a hash or md5 error, and extract it again.
- Use a data cable in a port on the PC, not a hub, with the Samsung USB Driver installed.
- Put the phone in Download Mode and flash with Odin3 v3.14.1. My step-by-step tutorial covers it.
Not sure which of the files goes into BL, AP, CP and CSC? I explain that in my firmware files guide. And if Odin keeps failing on your PC, Brokkr is a free alternative that loads the same firmware files.
If you still decide to use a patched build, that’s your call. Take it only from the original XDA thread, scan it with VirusTotal, and check the model number and file names yourself before you press Start, because the tool won’t do it for you.
Patched Odin questions
What is the difference between Odin and patched Odin?
Normal Odin checks the model, the carrier and the file hashes before it flashes. Patched Odin has those checks removed by a third party. Both use the same Download Mode connection, and the phone still decides what it accepts.
Is patched Odin safe?
There’s no way to prove it. Odin is closed source, and you can’t see what a patcher changed. Skipping the model and hash checks also makes it easier to flash the wrong or a damaged file. Use the normal Odin unless a guide for your exact situation says otherwise.
Does patched Odin fix SW REV. CHECK FAIL?
No. That message comes from the phone’s bootloader, which blocks firmware with an older bootloader version. Every Odin build gets the same answer. Flash firmware with the same or a newer bootloader digit instead.
Does patched Odin fix FAIL (Auth) or the FRP lock message?
No. The phone prints and enforces those, not Odin. Flash official firmware for your model to get the phone booting again.
Does patched Odin fix Model mismatch fail?
It hides the message, but the firmware is still built for a different model. Download the firmware that matches your exact model number instead of forcing it.
Which Odin version should I use instead?
Odin3 v3.14.1 is the one I recommend. If a very new phone gives you trouble on it, try Brokkr, which is free and open source.
Do you offer a patched Odin download?
No. I only host the regular builds, each with a SHA-256 you can check on the download page.
That’s everything you need to know before you decide on patched Odin.
If you’re stuck on an error, send me a message through the contact page. Tell me your phone’s model number, the firmware file name and the last few lines of the Odin log, and I’ll help you find the real cause.
