Yes im trying update to the newest att firmware and yes I got the Verizon newest firmware
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Then you'll have to wait until that version is released
[Samsung Galaxy S10 5G Guides, News, & Discussion] Gsklan:
its out already just aint uploaded anywhere att firmware update is G977UUCS5CTF6 thats the new updated come out July 24
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:

Is it possible to downgrade back to Android 9.0 from 10.0
[Samsung Galaxy S10 5G Guides, News, & Discussion] DracoNB:
Hey I just picked up a S10 5G Verizon model but unlocked.

I was hoping to test out Mint Mobile with it but wanted to update it as its on some very old Android 9 version.

I've heard that I might want to use the ATT version for Mint since its T-Mobile and better compatible, is that true? Not able to set APNs on Verizon version?

What version(s) should I use to flash so I can flash between Verizon and ATT if needed?

Also from the files you posted, this one keeps saying no mirrors found:

G977U_VZW_TB2_4.zip
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
1. APNs should work fine on Verizon firmware

2. I unfortunately can't do anything about AFH's mirrors being down. I'd love to have a multi TB Google Drive account, but that costs $$$$, so it would require donations from users
[Samsung Galaxy S10 5G Guides, News, & Discussion] DracoNB:
Ok, still waiting for my SIM card to arrive to can't test out the APN but heard they were locked by other people.

I managed to get the G977UVRS5CTF6 version from Friga for verizon, is that the latest?

I downloaded G977U_ATT_TD6_4 from the files you provided as well, or is there another version I should get from Friga that is newer?

Are those the same version so I can flash between them or will one prevent the other from flashing?

Frija says it doesn't support ATT CSC code so not sure how to look up versions from there.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
You need to read the OP again - more carefully. I would also highly recommend finding several "beginner's guide to Odin flashing"-type posts/threads here on XDA in order to familiarize yourself with the process more. Especially if you're going to be going back and forth between firmwares, being able to identify bootloader levels and which version you can flash at which time is going to be essential
[Samsung Galaxy S10 5G Guides, News, & Discussion] knyghtryda:
I'm curious what firmware all the ATT users are on. According to the ATT web page the latest firmware for the 5G is supposed to be TF6. However, I'm still on TB4 and no updates are being pulled. Also, the latest ATT firmware posted here is TD6 which isn't even listed on the ATT web page. Why is that? At some point I might just wipe and flash the VZW TF6, but I really don't want to wipe at this point.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
You have an AT&T device with an AT&T SIM and AT&T firmware and aren't getting OTAs?
[Samsung Galaxy S10 5G Guides, News, & Discussion] knyghtryda:
I normally use a T-mobile SIM, but I have tried it with both an expired ATT SIM as well as a live ATT sim and have gotten no OTAs past TB4. I previously was able to get OTAs even with an T-mobile SIM. I have also tried using the Samsung desktop software to look for the firmware updates and they say there are no updates past TB4, even though the ATT website lists at least 2 more up to TF6.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Strange, since they usually don't let you OTA without anything but a live AT&T SIM inserted.

Is it an original AT&T device? Or is it originally from Verizon?
[Samsung Galaxy S10 5G Guides, News, & Discussion] knyghtryda:
This is an original ATT device, direct from ATT. The only thing that had to be done was a sim unlock so that it could be used on T-Mobile.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
What does it say when you check for updates, when you have an active AT&T SIM inserted?
[Samsung Galaxy S10 5G Guides, News, & Discussion] knyghtryda:
It just says current software is up to date.
[Samsung Galaxy S10 5G Guides, News, & Discussion] elliwigy:
ur not using it on tmobile with a tmo sim in it? he suggested using an active att sim
[Samsung Galaxy S10 5G Guides, News, & Discussion] Alakazamm:
So the Samsung s10 5g model is the only sprint model at the moment that you can unlock the bootloader? Can you flash TWRP OR PHILLZ.? I'm been out of the game for a while but I m willing to buy the right model if I can obtain root and unlocked bootloader. Thanks for your help
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
This thread has nothing to do with unlocking the bootloader, installing a custom recovery, or rooting. I'm sure there are other threads that do address those things though
[Samsung Galaxy S10 5G Guides, News, & Discussion] robdagreat1688:
TF6

Does anybody know where I can get the new att firmware (TF6 ) thanks
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
I'll post the files as soon as I get access to them
[Samsung Galaxy S10 5G Guides, News, & Discussion] Mklubertanz:
ha.. yep, just realized that myself, was just coming on here to say forget my question... thanks for the answer though...
[Samsung Galaxy S10 5G Guides, News, & Discussion] y2jdmbfan:
So is your operating like an AT&T unit now? I'm debating on doing this. I wonder if it will pick up 5G in areas where available.
[Samsung Galaxy S10 5G Guides, News, & Discussion] XanoZuke:
Do you know if the Verizon lock when activating your phone on another network is gone with this? Because I'm locked out of my phone right now...
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
If you're referring to it being network/SIM locked, then flashing another firmware won't change that.
[Samsung Galaxy S10 5G Guides, News, & Discussion] XanoZuke:
I don't think it's a network lock per say, because when the phone starts with the foreign sim card, it registers normally, but after 2 or 3 minutes, the phone goes offline and the Verizon notification appears, telling me that "this phone cannot be activated on another network right now". So I believe it's a VZW configuration on the OS, rather than a network lock.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
That sounds exactly like a network lock to me
[Samsung Galaxy S10 5G Guides, News, & Discussion] XanoZuke:
A proper network lock wouldn't let my SIM card register to the network for even a second.
[Samsung Galaxy S10 5G Guides, News, & Discussion] cheapshot789:
When dont you just try att firmware
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
T-Mobile firmware added
[Samsung Galaxy S10 5G Guides, News, & Discussion] XanoZuke:
Exactly with I'll do.
[Samsung Galaxy S10 5G Guides, News, & Discussion] netnerd:
i'm waiting for u1 unlocked firmware.
[Samsung Galaxy S10 5G Guides, News, & Discussion] XanoZuke:
I tried flashing and it failed. Do you have to do something special in the process or just the normal stuff? Loading the 4 files into Odin and booting up the phone in download mode.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Have you read the OP?

Failed how, exactly? It may be an Odin issue. Telling us exactly what it showed in Odin and also on the phone itself will tell us why it failed
[Samsung Galaxy S10 5G Guides, News, & Discussion] tlbland0426:
You can't flash the T-Mobile or Sprint firmware on a Verizon device. It will fail in Odin. You can however flash the AT&T firmware because both devices are 977U devices. Since the other two carriers are 977T and 977P you will never be able to flash those firmwares through Odin on a 977U device.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
That's not always necessarily the case. For example, all US models of the Galaxy S7 and S7 Edge are cross compatible for firmware, despite them all having their own unique model numbers. So Samsung might have implemented the same thing here. That's what we're trying to find out
[Samsung Galaxy S10 5G Guides, News, & Discussion] tlbland0426:
Well it's a no go here. Already tried flashing them all on my VZW 5G and they all fail except the AT&T firmware.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
What's the specific error that you get in Odin? Also, does any error message appear on the phone itself, at the bottom of all the text that normally appears in Download mode?
[Samsung Galaxy S10 5G Guides, News, & Discussion] tlbland0426:
Fail! (auth) as soon as it starts flashing. I figure it's because there is a mismatch due to model numbers.
[Samsung Galaxy S10 5G Guides, News, & Discussion] XanoZuke:
Tried flashing the AT&T firmware on a VZW S10 5G:
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
You're using a very old Odin version. That's why it failed

Bootloader 5 files have been added for AT&T firmware - build TF6
[Samsung Galaxy S10 5G Guides, News, & Discussion] denpad2010:
Hello good evening, I'm trying to flash my vzw s10 5g with att software, but in Odin when try to enter the AP file gave me this error.... md5 error Binary is invalid, I downloaded the wipe AP file... Should I try the other one, BTW that one downs have the BL and CP but I saw yiy have that files separated.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Try re-downloading the file. I always verify the files in Odin before I zip them up, to make sure that they pass the md5 check

EDIT: Which version of the firmware are you trying to flash? I'll double check it
[Samsung Galaxy S10 5G Guides, News, & Discussion] denpad2010:
ill try to download again...its the G977U_ATT_TF6_5_wipe
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
My local copy of the file failed and so did the one that I downloaded from the OP links. No idea how I missed that - sorry. I'll get it fixed and re-uploaded
[Samsung Galaxy S10 5G Guides, News, & Discussion] denpad2010:
Thank you, I got a copy of the firmware somewhere else, and was able to flash the AT&T firmware, I can confirm that phone is unlocked, no Verizon activation issue 👌

Now I have a question, is the 5G disabled?? I'm using a tmobile sin card and only get lte when I have 5g with a s20 plus
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Probably a band/coverage mismatch, between AT&T and T-Mobile.

In other news, apparently renaming a file breaks md5 integrity? Who knew. I coulda sworn that I've changed file names in the past without issue. But that appears to be what was throwing it off. So that's been fixed and re-uploaded
[Samsung Galaxy S10 5G Guides, News, & Discussion] denpad2010:
i am not an expert but i guessed that was the issue...thanks for your help buddy have a good day.

You are on ATT software. To get OTA updates you need a AT&T active sim. You are also very unlikely to come across a maintained archive of ATT software that isn't sketchy as ATT does their updates OTA.

Personally it's why I switched back to Verizon's ROM and did what this guy did. But I only changed network, not sales and network as that bugs something out and causes a persistent notification that you can't get rid of.

When u install firmware. i have to factory reset first ?
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
You can't install 9.0 because your device is on bootloader 4. The files that you're trying to flash are from bootloader 1 and are two years old

[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
You can use Frija, just like it says in the OP
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Well of course. The OP says that AT&T firmware is never available on Frija. So if you want G977U firmware, you have to get Verizon
[Samsung Galaxy S10 5G Guides, News, & Discussion] valera.novikov0063@gmail.:
Are you saying that all the firmware from Verizon is suitable for AT&T devices? I apologize in advance if I ask stupid or incomprehensible questions. I communicate with you using translation.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
They have the same model number, so yes, AT&T firmware can be flashed to a Verizon device and Verizon firmware can be flashed to an AT&T device.

If you currently have AT&T firmware, then changing to Verizon firmware would require a factory reset. If you don't want to factory reset, or if you want to stay on AT&T firmware, then I would have to create a special firmware for you
[Samsung Galaxy S10 5G Guides, News, & Discussion] valera.novikov0063@gmail.:
Recently, I had a sad experience with this device. I installed Verizon firmware on it. When turned on, the phone asked for a PIN code, then 5 seconds passed, and it lost the network. The same thing happens with each subsequent reboot. I tried to install different Verizon firmware - the result is the same. What can this be related to? That's why I can't upgrade to new firmware versions, and I use the latest TLN posted by you on AFH for my AT&T G977U.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
You would need to post a picture or screenshot of this "PIN code" in order for me to understand
[Samsung Galaxy S10 5G Guides, News, & Discussion] valera.novikov0063@gmail.:
I'm talking about the PIN code of the SIM card
[Samsung Galaxy S10 5G Guides, News, & Discussion] valera.novikov0063@gmail.:
It's not about the PIN code. Even with code verification turned off. When you turn on the phone, the network appears, and after 5 seconds it disappears. As soon as I return the firmware to AT&T, the problem immediately disappears.

The problem is that you flashed bootloader 8 firmware, but no such firmware exists yet for AT&T. You cannot flash bootloader 7 firmware to a device that already has bootloader 8, so now you're stuck until a bootloader 8 version is released for AT&T

El problema es que le flasheaste un firmware de binario 8, pero tal firmware aun no existe para AT&T. No se puede flashear firmware de binario 7 a un dispositivo que ya tiene binario 8, asi que ya estas atrapado hasta que salga una version de binario 8 para AT&T

Hey everyone.

So I found this phone at work in one of our drawers and it hasn't been touched in forever and no one knows who it belonged to. It was a work phone so I know it's AT&T. It's a Samsung S10 5G model SM-G977U

.

It has a security error this phone has been flashed with unauthorized software.

I've tried various versions of Odin, including 3.14.1 3B Patched, as well as the official latest.

I've tried different versions of the stock firmware from this thread including G977U_ATT_TB1_4 and G977U_ATT_SJM_3.

However, Odin always errors out with the error below.

I'm not sure what else to do to get this thing flashed and wanted to see if anyone here knew what the issue is.

Thanks for any info!
