I have never had any trouble with either Frija or Samfirm, but now they both find the firmware. Download fine until CRC check, then they say they don't match correctly. Not sure whats up.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I have no idea what "CRC" is, but I have never checked that box in SamFirm. As long as the files pass the md5 check in Odin once you load them in, they're perfectly fine to flash
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] mopartonyg:
I also tried unchecked that box and the firmware always fails to flash. Have been using Frija since it first came out with 0 problems.

CRC is a redundancy check to make sure the data transfers correctly. At least that's what Google says.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I just tried doing it now with SamFirm and it said the CRC matched. It's decrypting the .enc4 file right now. This is G988U1 XAA TFB build
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] mopartonyg:
Thanks I will keep trying. Maybe its windows 10 causing a problem
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I also have Windows 10. SamFirm found the file, CRC matched, download, decrypted, extracted zip, and Odin loaded all the files - all without any errors or issues. But yeah, I'd recommend trying with a different computer or internet connection
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] mopartonyg:
Thanks for you input and help
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] tyrone1:
It downloads the whole file.. it's just at the end it does crc check and the crc doesn't match... Either way I'm done.. updated within phone.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
It matched for me earlier today when I tried it
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] tyrone1:
Just tried on 3rd computer and got same error.

Tried xaa and Tmb CSC. Same result... Wonder why this happening to some and not others..
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:

ATG2 is out for U1 :cowboy:
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] tyrone1:
Strange I got all the ota updates until this one.... If it doesn't push into my phone in a few days I'll manually update it in Odin.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
It could possibly get pushed to your phone ota. It shows on sammobile dropping just 2 days ago on the 26th. Good luck ?

Is the S20 like the S10+ where a sprint version (SM-G981UZAASPR) of the phone will switch to the ATT version when you factory reset and put in an ATT SIM card?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] jcrompton:
Yes I think so especially with U1 firmware
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
No, it won't switch to AT&T firmware if it has U1 firmware. By definition, U1 firmware is bloatware free and contains no carrier apps, symbols, or logos whatsoever
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] DEATHCIBELS:
The phone will only allow you to change carrier branding if it's unlocked. Once the phone is Network unlocked, it will allow you to change from any carrier's pre-configured software simply by switching SIM cards. (Be aware, it will factory reset your phone)
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] maddoggin:
can someone provide link to flashing u1 firmware from tmb firmware? please? im on tmobile locked version and would like to flash bloat free u1 firmware is this possible?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Incorrect.

1. The phone doesn't need to be unlocked in order to manually change firmware, from one carrier to the other.

2. The automatic firmware conversion that happens when you insert a different carrier's SIM (after the phone has been unlocked) does NOT perform a factory reset

That information has already been given many, many times - both in the OP and also in the thread
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] DEATHCIBELS:
1.) Nobody stated that the phone had to be unlocked to switch firmware, I said the phone must be unlocked to switch carrier branding with only a Sim card which is 100% true.

2.) New to the S20 scene, but my TMO S9 definitely factory reset when I switched SIM cards.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
"Changing carrier firmware" is the same thing as "changing carrier branding".

The automatic carrier conversion feature has never included a factory reset, dating all the way back to when they first introduced it on the S8
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] DEATHCIBELS:
Since you always seem to be right (with no sources cited), please take a look here. https://www.reddit.com/r/GalaxyS9/comments/9yqjgi/how_to_change_you_csc_with_sim_card/

Download Frija tool HERE and type your model number, for unbranded S20+ type "SM-G986U1" and for CSC put "XAA"

Download Firmware and follow OP's instructions.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
LOL. That post is about the UK model, not the US one. And even so, performing a factory reset via recovery is listed as step #4.

This is the S20 Ultra thread, not S20+. Assuming he has an S20 Ultra, he should use SM-G988U1
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] DEATHCIBELS:
Dude, you must be really fun at parties... or in general. I just found a quick source to show you what I was talking about. I can't say he did the most optimized route of changing carrier branding, but IT DOES SHOW THAT IT FACTORY RESETS. Sorry for yelling, but didn't know if you'd hear me past your precious ego.

My bad, I didn't state that I was using an example, perhaps I should edit it.

Anything else? Find a new way to spend your time, I'm trying to help this dude, and you're just being a scooby douche.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
In the Reddit post that you linked, the poster's instructions state for the user to perform a manual reset. That's not the same thing as the conversion process automatically performing a factory reset.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] y2kdread:
Another very specific question for everyone.

If I have a S20 on sprint (SM-G981UZAASPR), buy an unlock code and apply it to the phone, factor reset and rebrand the phone to ATT, is the phone still network unlocked?

I am not sure if I would need to buy the unlock code before/after doing the factory reset and rebranding to ATT.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. Sprint phones don't have, or use, unlock codes - they never have and never will. That's why it doesn't ask you for the code when you insert a different SIM. SIM unlocking a Sprint phone is much more complicated and difficult than a simple little code.

2. The phone will probably do the re-branding for you automatically, and no factory reset will be necessary
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Well I was able to get the latest ATG3 for U1. It shows an ATGL for TMB U available but frija couldn't find it.

Are the letters more recent than the numerals at the end in the PDA [MENTION=3163377]iBowToAndroid[/MENTION]

Edit: I believe i figured it out if it goes by the latest changelist then it's the LETTER.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Samsung follows the standard binary alphabetization sequence, which is what computers use. Correct - numbers come before letters. So TG3 would technically be older than TGL.

Very odd: Neither SamFirm nor Frija will find G988U TMB firmware as of right now, using Auto. You have to manually input all 3 fields. Then it works fine. I've only ever see that happen with VZW firmware - theirs always requires manual input
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Okay I'll try again after work this evening. I tried manually with frija and must have entered something wrong because it still didn't find it for me. Thanks for the explanation :good:
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
All 3 fields are identical except for the CSC - you have to change the 3 letters that come immediately after the first U to "OYN"
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Is this correct because it won't load for me :confused:
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Auto now works, but reverts to build TF9. So it looks like they've pulled TGL - might have had a bug that wasn't caught, etc
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Right on!

Appreciate your feedback bro
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Jason928591:
I went from Verizon to the T-mobile firmware and everything seems to work good. Just wondering though for step 4, does it matter which version of the CSC file you flash with?(It wasn't specified which one to use) I flashed it with the non HOME CSC, and just wondering if that will affect anything?

I'm not getting any updates for the new firmware that came out: G988USQU1ATGL. Anyone else on T-mobile get the latest OTA update? Thanks
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Febby:
Were you able to successfully download the TMB ATGL firmware?

Edit: I just read that the TGL build was maybe pulled for now. If you find a way let us know. :)
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Yes sir I sure will!

I'm always creeping the SamMobile website ??
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Febby:
I got the ATGL firmware to download for the G988U (T-Mobile) using frija

I entered the following manual info:

pda: G988USQU1ATGL

csc: G988UOYN1ATGL

Give it a try and tell me if it works. :)
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
I will give it another try when I get off work this evening.

Did it load in Odin and able to flash?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Febby:

It sure did DL and flashed correctly. :P
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Hmmmmm still doesn't work for me.

Pretty sure my MODEL and CSC are correct on top?

Man you don't have to do that. It'll show up eventually. I appreciate the offer tho ?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] 1JRB:
need a little guidance

I have the S20+ with the snapdragon processor. I was with Sprint, switched to verizon. Phone will make and receive calls and send and receive texts except pictures and videos. Also continuously tries to register to with the Sprint network even though it has a verizon sim in it. Sprint blames it on Verizon and Verizon blames Sprint. I used Odin and the tried flashing it but the Software Version still shows sprint no matter what I do. From what I have read it seems like I need to root my phone to wipe out all sprint software and bloatware. But I still want my phone to be secure. Do I unroot it after I root it then flash it with an unlocked version and with a locked bootloader? Does that put my phone back to stock but without the Sprint software and bloatware?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Which model phone do you have?

The US models can't be rooted I'm pretty sure.

It should wipe your DATA if you use the CSC without the HOME when you flash with ODIN
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Delete.

Duplicate post...
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
I think you need to read a little more carefully.

1. Root has not been mentioned anywhere the OP or in the thread - and that's because the US models of the S20 can't be rooted.

2. If you're trying to remove all of the Sprint software, the instructions for doing so have been clearly laid out in the OP and extensively discussed in the thread. So if the Sprint software isn't going away, there's something that you're not doing correctly
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] 1JRB:
Maybe I am misunderstanding then. I have the actual bloatware removed. But here is a screenshot of the software version. You can see the "SPR" in there. Ill try again. I followed the method in the post. I must be missing a small detail or something because I own a business working with electronics and programming. Im not familiar with phines though. This is my first go at it. I was told also that my phone may not have ben unlocked all the way or correctly before they took out the Sprint sim card and replaced it with the one for Verizon. Thanks and I'll keep trying

I tried attaching the screenshot but it only gave me the option to add a URL instead of being able to attach it directly
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. If you successfully flashed U1 firmware, then everything should be working fine.

2. It appears that, for now at least, the phone is unlocked. You wouldn't get any signal and wouldn't be able to make calls and texts otherwise. Whether it was done correctly depends on who did the unlock
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] j0nkatz:
Which firmware do I need to make a U a TMB device with splash screen and the TMB apps?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
That's already stated in the OP
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Okay got it downloaded finally. I bit the bullet and downloaded from sammobile to my phone while I slept ?

It only took 6hrs to get it

Edit: I have it uploaded to my google drive if you want it let me know..
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] j0nkatz:

I'm looking for TMB/TMB/ATT
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:

If you look in the screenshot I took today after flashing my phone for the 10th time it shows the Baseband Version as the Verizon version. Also was one the phone with Sprint and confirmed that the phone and sim are unlocked. But if you look at the Service Provider SW ver. it is clearly showing Sprint still. Phone still tries to register on the Sprint network even though it has a Verizon sim in it. I dont want to fill the thread up with this and I searched the forums with he word "beginner" looking for a beginners guide to this but no beginners anything came up in the search. Only leads me back to this thread every time. PM me the links to the beginners guide if you know where it is. I don't mind reading it for myself but I have not been able to locate that thread. Here is a screenshot of what I am referring to.

Just need guided in the right direction. Seems like I need my SW to be plain Samsung or Verizon. Firmware is from sammobile
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] n0kia916:
Thanks!

Thanks for the upload! Frija was stopping midway for the download.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
If I were you I'd download in frija on AUTO the following G986U VZW ATFG and flash the USERDATA maybe that will fix your problem.

I'm not certain it'll help but it's worth a try ;)
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] 1JRB:
I tried that, I got "Error 102: Unable to find Firmware for VZW ATFG" then "Please make sure all fields are correct or use manual mode"

Also tried it typing in the VZW and ATFG separately too. I ran the program as administrator also.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
It pulls up just fine for me :confused:

All you need to input is MODEL & CSC then click AUTO...check update
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
If they pull a specific version, it's usually because something in it doesn't work correctly. I would advise against anyone flashing this build to their device

The steps for getting from U1 to a specific carrier's U firmware have already been given in the OP

Frija will find VZW firmware on Auto. If you're using SamFirm, Manual input is required
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
1. When it comes to firmware, there is no such thing as "(carrier name) version". Firmware is universal, and multiple carriers will get the same update/version.

2. If you want plain firmware, then flash U1 - just like the OP states
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
Not sure if they totally pulled it [MENTION=2587828]Febby[/MENTION] was able to get it from frija and installed no problems.

I was only able to get it from sammobile. I too was successful in flashing and no problems here.

Crazy thing is now I'm able to download the U TGL SPR who knows? BUT if i do encounter any issues i will advise :good:
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Ohhh okay, good. If another carrier gets the exact same build, then it means that build is fine. If it had a bug and they fixed it, they would issue a new build with a slightly higher letter at the end.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] 1JRB:
OK but what ab out the Service Provider SW Ver? I'm pretty sure that is the main issue with my phone. You can see it still says SPR in the screenshot I posted. The phone is unlocked and has the Verizon sim in it and is on the Verizon network. I need to change that for it to work correctly and neither carrier has been able to help with that. I have performed the unlock steps multiple times and it says its unlocked. Also I still need to figure out why I'm getting those errors with Frija. And I understand you saying there is no such thing as carrier version but still it does state a carrier SW ver in the information about the phone and mine is SPR "Sprint" all the way. I was told that When I get that switch to where it says no carrier SW Ver or to VZN SW Ver "Verizon" that my phone will work correctly. I read the OP multiple times, and tried to do what it states. I'm about to just sell the phone to someone who has Sprint and buy one that is unlocked again or one that is Verizon so I can use all the phones features again. Thanks

Okay I got Frija working, was an error on my part.

---------- Post added at 09:24 PM ---------- Previous post was at 09:01 PM ----------

In Frija you can enter PDA, CSC, and phone. Will entering those also help change what I'm trying to change or accomplish? If so what should I put in those fields?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Nope.

G986U1 for Model.

XAA for CSC.

Click "Check Update".

Boom.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] 1JRB:
Okay thanks! In the OP it states to put in the SIM upon boot. So as soon as the Samsung logo appears or when the home screen is booted? Just want to make sure I got it right. Also in Odin I do not load a USERDATA file for the flash, correct?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] 1JRB:
The USERDATA file you mentioned has to be put in manually in odin after I get the files from Frija correct? Does it matter which firmware version I get that from as long as it is for my model?
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
If you want plain firmware with no carrier bloat, that's U1. USERDATA is carrier bloat, so that only exists in U firmware - not in U1.

You only need to worry about USERDATA if you want to convert the phone to Verizon firmware instead of leaving it plain with no carrier bloat
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Jason928591:
Any idea why the TGL update was pulled? I installed it and I've been having issues with GPS signal, ever since I flashed from Verizon firmware, to T-mobile. I don't remember having issues before with it so, Not sure if anyone else ran into this problem as well.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] j0nkatz:
Yeah, I tried to shortcut and not go to U1 in between U firmwares. I did that and now I'm golden. Thanks to you and IBowToAndroid!
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] JDBarlow:
I don't think it was pulled. Both Sprint and T-Mobile show up on Sammobile's website. I've been running TGL for several days on AT&T with zero issues with my GPS.
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
SamMobile won't pull a specific version just because Samsung does. If they already pulled the files and uploaded them, then they stay there. But that version has apparently been released for Sprint at minimum (and maybe other carriers) so it's possible that it doesn't have any bugs after all. Or that the bug was only related to T-Mo 5G and therefore doesn't affect other carriers
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] Jason928591:
I ended up re-installing T-Mobile 'ATF9' then the update popped up for the TGL firmware and updated. I was hoping maybe it was just something I didn't flash correctly and would fix it. That GPS issue definitely looks like it affects some people with the S20. I have yet to try out my GPS on google maps again to see if it's still the same.

It definitely looks like a known issue though:

I don't know if this is true but it seems like it.

I bought my phone from AT&T and after receiving it, I changed the software from AT&T to Unlocked from this thread. I decided to get the Note 20 Ultra and wanted AT&T to unlock this one (its fully paid) from AT&T.

I entered the IMEI number from AT&T's unlock portal and it says the IMEI doesn't match an AT&T device and is unlockable. So I called AT&T and they had the same issue and had to escalate it to another dept.

Do you think by changing the carrier software makes the IMEI unrecognizable to the original carrier?

you change from AT&T to no carrier
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] iBowToAndroid:
Carrier models end in U. Therefore U firmware is what has the carrier bloat and features. So if that's what you want, then yes, you need to be entering the U model
[Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News] xstation:
Thank you very much for confirming .

As for going back to stock unlocked (no bloatware) I enter SM-988U1 as the model and XAA to get the correct firmware?
