Oh really! You didnt announce? I just finally got around to flashing the SJM firmware yesterday, followed your tutorial about removing both user data, yup, didnt lose any data.

Would download and flash this,

Thanks!

No ATT android 10 yet? I', on ATT, can i flash this without losing data? I hate Verizon Fonts!

but i can manage if i wont lose data while flashing.

Hi, i've downloaded the verizon android 10 files, can i cross flash? without losing data?

i'm on ATT, SJM firmware.

AT&T Android 10 for G977U

Any luck on getting the AT&T G977U firmware for Android 10 (Q)? Hoping to flash from the latest Verizon Update, switched to Google Fi so hoping the GSM support in the AT&T firmware will work better for coverage / getting LTE internationally.

I believe the latest version is G977UUCU3BSL3 - Looking for that one or later, thanks!
[Samsung Galaxy S10 5G Guides, News, & Discussion] Simpuhl:
Can someone please tell me which one to use.

I have a Verizon Samsung s10 5g and want to flash to att, it's still android 9. I'd like to go to android 10 if possible also.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Android 10 files for AT&T haven't been added. So you can flash Android 9 and then OTA to 10 if you like, although you'll probably need to insert an active AT&T SIM into the phone in order for it to do the OTA
[Samsung Galaxy S10 5G Guides, News, & Discussion] Simpuhl:
I don't mind that and I have an Active ATT sim inside as we speak, I am just not sure exactly which firmware to download. theres a few folders on the site. Also all the downloads just say searching for mirrors
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
How to interpret the folder names is explained in the OP. I can't do anything about AFH not returning any mirrors though. I've found that reloading the link or using a different browser can solve that problem though
[Samsung Galaxy S10 5G Guides, News, & Discussion] Simpuhl:
Thank you, I downloaded all the files, your post says USERDATA is only needing if converting between AT&T and Verizon firmwares. But I don't see a USERDATA file?

I hope I did it correctly, its doing it: https://i.imgur.com/f5rv8TG.png

Didn't use any USERDATA file

Thank you for your help

Edit:

We now have an ATT logo and it seems to be working, restoring phone from online now and its showing the 5gE icon :)

odin failure

Using Odin v3.13, have G877U (verizon) trying to flash verizon firmware G977UVRU1ASE8 provided on the 1st page.

<ID:0/007> Added!!
<ID:0/007> Odin engine v(ID:3.1301)..

I tried plugging into a different USB port (got a different COM ID), but same problem. It sits at "SetupConnection" for 15-20 minutes, before bailing out.

Any ideas?

I have s10 5g att, but i use metropcs, how to update to android 10? I can change the firmware or rom for other rom unlocked?
[Samsung Galaxy S10 5G Guides, News, & Discussion] yanechiko:
Hi,

Could you upload AT&T 10.0 ROM? They are already out:

G977UUCU3BSL3

and

G977UUCU3BTA1

I found them on easy-firmware but I'm not 100% if it's legit, check this out.

The official att&t website says that latest update is G977UUCU3YTA1 for S10 5G

//edit

PS: I'm just asking because I bought phone from Verizon originally and then installed AT&T ROM, which works well.

However, I wanted to try the new Android 10.0 but only VZW version is uploaded here. Now I can't downgrade to other AT&T version, so I can't use my SIM.

I was trying OTA when I had my AT&T installed, but I haven't get any update for last 8 months, that's why I tried Verizon's 10.0 ROM.
[Samsung Galaxy S10 5G Guides, News, & Discussion] psygnosi:
Tried to flash AT&T 9.0 pie to Verizon Android 10 and it failed via latest odin. I think its because you can't downgrade to android 9. I have Verizon SM-G977U with latest android 10. I'm currently downloading latest At&T Android 10 G977UUCU3BTA1 (which should be newer or equal to the Verizon one) and will flash to see if it works. Crossing my fingers.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Of course you can, as long as you're flashing a bootloader 3 version
[Samsung Galaxy S10 5G Guides, News, & Discussion] psygnosi:
Okay I just read up on it. Its suppose to be G977UVRS3ASJK Verizon android 9 which I was suppose to flash. My bad. will try again. Thanks.

Okay it worked.
[Samsung Galaxy S10 5G Guides, News, & Discussion] oakfan1283:
Is there any way to download and save the update? I'm going to use my co-workers sim card tomorrow to update to ATT Android 10, would like a way to save that file so if I need to reinstall in the future.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
If you're referring to pulling the OTA zip, no you can't do that. But that wouldn't do you any good anyways. You can't reinstall an OTA zip, because it can only be applied when coming from whatever version you're currently on. If you want files on hand for future reinstallation, you need the full Odin firmware
[Samsung Galaxy S10 5G Guides, News, & Discussion] oakfan1283:
So for whatever reason I could not get the update to download with my friends active ATT Sim card, I ended up breaking down and bought the odin file to flash.
[Samsung Galaxy S10 5G Guides, News, & Discussion] Shelbyz8640:
Is it real

I cannot find this update version on at&t website as being the latest or even a previous version. Have you actually tried it yet? Did it put you on android 10? Any bugs you have noticed? Thankyou.

[Samsung Galaxy S10 5G Guides, News, & Discussion] chillsen:
[MENTION=3163377]iBowToAndroid[/MENTION], I appreciate you curating the files and also this thread. I got a brand new S10 5G but I noticed I was on Android 9 last week and tried to update and thats when this debacle began. I had firmware G977UVRU0ASDG which I still don't know where it is from or from what carrier however it never detected new firmware/updates/security patches. I checked software info and it was all original debut software.

I hesitated and did everything after some reading and took the plunge. I added the CSC home tar file and unchecked Userdata but it still factory reseted. It's not a big deal I guess. Not sure what I did wrong. However RCS works now and i just tried an update check and it detected Update 8 to begin downloading so now I know I'm correctly connected to VZW's network. Appreciate it much.

Also what does

SDG (VZW) mean? Maybe its a clue as to where this phone originated from.... thanks for everything though. Only thing that will be a headache is all my authenticator codes... crap!!!
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
1. It's been a long, long time since I've seen Samsung use bootloader 0 on a release version of software. My guess is that you somehow got a device that had a pre-release testing/beta version on it. I've never seen that build mentioned or listed anywhere until now

2. What build did you flash?
[Samsung Galaxy S10 5G Guides, News, & Discussion] chillsen:
[MENTION=3163377]iBowToAndroid[/MENTION], wow that is super interesting. So the firmware was so beta it didn't even get recognized by VZW? haha wow. A reputable seller on ebay was selling these as a flash sale for $525 so I had to jump on it coming from a shattered Note 8. It mentioned NO retail box but accessories and phone itself was brand new (had the screen protector, etc.)

I flashed G977U_VZW_SL2_3, I saw that I didnt have to unzip the HOME_CSC tar file but I did notice unlike the other file names it did not end it ".md5" It seemed to be the most recent VZW FW. After that I got 2-3 new updates instantly and now I am finally in the middle of restoring with SmartSwitch.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
1. tar or md5 files never have to be unzipped, so I'm confused about what you mean by that

2. HOME CSC isn't an md5 because I don't get access to that file. I create it myself by extracting the regular CSC, removing the parts that initiate the factory reset, and then repacking the tar.

3. Obviously there's something else that's triggering the reset, if you used the HOME CSC and it still wiped during/after flashing. That's usually caused by the USERDATA partition in the AP file, which is something that I've only seen on AT&T firmware up until now. So I'll work on creating a "no-wipe" version of the AP file, and maybe you or someone else can test that for me, to check if it successfully avoids performing the factory reset
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Okay, I've added a no_wipe AP file to the VZW SL2 folder. If someone could try it and report back, that would be cool - I don't have an S105G myself. Use the no_wipe AP along with BL, CP, and HOME CSC, and see if it saves user data and does not perform a factory reset when flashed. I don't know for sure if it'll work until someone tests it, so you're responsible for backing up your own data, taking proper precautions to avoid an FRP lock, etc.

Thanks!
[Samsung Galaxy S10 5G Guides, News, & Discussion] chillsen:
Oh I'm glad you were able to create a no_wipe AP file! Thank you so much [MENTION=3163377]iBowToAndroid[/MENTION]!!!

Noticed it's a full gb less in size! that's how big the userdata was in AP? dang
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
1. As already stated, I don't know for sure if it will avoid the wipe until someone tests it.

2. Yes, the standard AP file (with userdata partition) is 5.5 GB uncompressed and the no_wipe AP is 4.5 GB uncompressed. The standalone USERDATA files for other U models are always more than 1 GB uncompressed, so that's pretty standard
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Verizon has bootloader 4 rolling out (build TB2). No signs of bootloader 4 from AT&T yet, so applicable precautions to those who wish to flash between firmwares

Hey, Bud!

Which version did you ended up downloading? Same exact issue. S10 5g on Verizon trying to flash to AT&T but I'm not very familiar with how all this works. Would you let me know which file on the link did the charm? TIA
[Samsung Galaxy S10 5G Guides, News, & Discussion] Absonoob:
I have the exact same problem as chillsen. I think we even bought the same phone from the same ebay seller because I paid the same price and I have that same G977UVZWOASDG/ G977UVRUOASDG number scheme going on. Can't update. Last security patch on it is dated March 1, 2019 and this phone was officially released in April last year, I think.

I was about to go nuts due to the amount of searching/ researching and trial and error I've been engaging in to solve the problem and finally it looks like I may have found it. Gonna do some more reading in the thread first though.
[Samsung Galaxy S10 5G Guides, News, & Discussion] Absonoob:
Ok, I downloaded the file entitled G977U_VZW_SL2_3_AP_no_wipe.

I extracted it and one file came out called AP and it was a tar file.

Do I not need a bl and csc file as well for odin?
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
And a CP file, yes. So download the other file that's in the SL2 folder
[Samsung Galaxy S10 5G Guides, News, & Discussion] Absonoob:
Got it downloaded. Gonna try it all with odin now. I'll be using the home_csc file because I want to try and keep my data. In any case, I've backed it up with smart switch.

This is a first for me.

Here goes nothing...

---------- Post added at 01:20 AM ---------- Previous post was at 12:54 AM ----------

Just trying it out before I hook my phone up to the laptop, I noticed that the home_csc file, which is a .tar file, shows up in the csc box when I click it, but nothing happens over in the log box to the left.

Is that right?
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Yes. I don't get access to the HOME file by default - I have to manually create it by extracting the regular CSC, removing the parts that perform the reset, and then repacking the file. So since it doesn't have an .md5 extension, Odin won't verify the checksum
[Samsung Galaxy S10 5G Guides, News, & Discussion] Absonoob:
I'm getting some kind of error. Can we post pictures here?
[Samsung Galaxy S10 5G Guides, News, & Discussion] Absonoob:
Ok, I've got to go to work and I'm without a phone. In the interest of moving things along because I don't know when I'll get a response to my question, I'm going to take a chance and post the pics or links to the pics of the error I got. Hopefully, that doesn't break any forum rules. I just want to try and speed this up a bit so that I can get back use of my phone.

It went through the process with odin all the way and odin said "pass" when it was done. The phone then began to boot and came to the following screen, where it remains:

[Samsung Galaxy S10 5G Guides, News, & Discussion] cwelch:
Hi, so I've gone through the history of this post but still have a question that doesn't seem to have been answered. If I flash my VZW phone to ATT firmware, will I still be able to access the CDMA bands and use other CDMA MVNOs? I live in an area with limited/no GSM access for 3G bands and would like to retain access to the CDMA 3G bands. Thank you so much!
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Why do you want AT&T firmware if you don't have AT&T? Makes no sense to me. Anyways, the answer is no. There's zero CDMA support built into the AT&T firmware whatsoever
[Samsung Galaxy S10 5G Guides, News, & Discussion] cwelch:
In short, the APN restrictions on the device which I assume are by Verizon make it particularly difficult to find a compatible MVNO, it is because of this that I was hoping to use the ATT firmware; which I presume does not restrict APN profiles, to access an MVNO.

On my S8, I'm able to manually create and edit APN profiles, however, for some reason the entire APN section on my S10 5g is greyed out and unable to be changed. If I quickly select Settings>Connections>Mobile Networks>Access Point Names after inserting a VZW or VZW MVNO SIM I can edit and add profiles but after exiting the settings it goes back to grey. I've found that the device retains these APN profiles even if they aren't displayed which has enabled me to use an MVNO until today.

I know it sounded like a stupid question but I just wanted to be sure that the ATT firmware prevents access to CDMA bands even if the device still has the antenna/hardware to access them.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Hmmm I wasn't aware that that was the situation with the APN access. You could try asking your provider if they have a way to push the APN profile to you. Certain carriers either do it automatically when your SIM is inserted into a new device, or they can force push it to you. It shows up as a message on your device, and there's a button to tap to install the APN profile.

You said you could use it until now? What has changed to where you now can't do the same thing?
[Samsung Galaxy S10 5G Guides, News, & Discussion] cwelch:
Thanks, I'll ask about an APN push with with my carrier when I get some time.

Nothing suspicious changed, I just restarted the device at the end of the week as per the usual and it suddenly lost access to mobile networks via the MVNO SIM. I didn't update the device, touch the APN profiles, reset network settings or even adjust the roaming status, it simply stopped working. Using the previously described method I was able to confirm that the APN settings were still the same and I completely re-entered them after a network settings reset just to be sure that wasn't the cause. The SIM still seems to work though as when I'm connected to a wifi source I can send SMS and MMS messages and it will enter my phone number into the appropriate field in the About section of the device. Unfortunately, wifi calling doesnt seem to work on this carrier so I can't just carry around another device as a hotspot lmao. Guess I'm stuck using my S8 for now!

I definitely appreciate the input even though this is completely out of the wheelhouse of the thread.

EDIT: So after some random try and fail troubleshooting I performed a network settings reset but placed the OG Verizon SIM that shipped with the device in the SIM tray, nothing happened on the surface but after entering the MVNOs APN profiles again the issue seems to have solved itself and has gone back to the original state. The APN settings are still grayed out and I'm unable to edit them without the trickery referenced above but the phone is working again. What a cluster f***, thanks Verizon ?

Newbie here... I tried to read most of the comments and from what I saw it seems it's not possible to flash the G977U in order that it will work with Sprint. Is that the case? I'm kind of a moron as I got the G977U thinking I'd be able to flash it to work with Sprint. I just wanted to confirm before declaring myself an indefinite moron.

p.s. iBowToAndoid... you are pretty awesome for helping others out like you do and sticking with the thread. Kudos to you!
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Sprint's model is the G977P, so you can't flash Sprint firmware to a G977U. But... Technically Sprint doesn't exist anymore. So no matter whether your G977U is Verizon or AT&T, it should work fine with them now that Sprint customers technically run on T-Mobile, as long as the phone has been SIM unlocked from its original carrier
[Samsung Galaxy S10 5G Guides, News, & Discussion] gabe23111:
It's not working now with my Sprint SIM card which is why I was asking. I did get the phone with an unlock code via a sticker that came on the box (screenshot attached) and unlocked it (I assume that was for SIM unlock). When you mentioned it should work fine, I'm assuming without flashing at all?

Thank you for the quick reply.
[Samsung Galaxy S10 5G Guides, News, & Discussion] iBowToAndroid:
Historically, you haven't been able to activate a new phone on Sprint just by inserting the SIM. You always had to contact them in order to have the device manually activated in their systems. But I have no idea how the activation protocol works now that things have been converted to T-Mobile. You may need an entirely new SIM card. Contacting customer service is going to be your best bet, if you have any issues
