1. The files that you get from Frija does not include USERDATA.

2. If you look for TMB files in Frija you had to put SM-F900U1 not SM-F900U. So basically what you get is the same as XAA files.

So that is why I am a little confuse and that is why a new TMB USERDATA is not available except for the one that you have available in your links (USERDATA_TMB_F900USQU1ASD4_CL15782089_QB23028580_REV00_user_low_ship_MULTI_CERT.zip). Tried yourself in Frija and see. I have search for a newer TMB userdata in the internet a great deal and can find a newer one. That one that is available is for Android 9 and all new firmwares are Android 10.

If you go to Sammobile this is the files you get for TMB (F900U1UES4CTJ5_F900U1OYM4CTJ5_TMB.zip). Notice the U1 and it does not contain the USERDATA file.

If you can help getting a newer one I will greatly appreciate it.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Sorry, I forgot that all carriers but AT&T refused to carry the Fold, after Samsung fixed the pre-release issues. So no T-Mobile firmware exists for it, past bootloader level 1.
[Samsung Galaxy Fold Guides, News, & Discussion] ellopr:
Thanks for the information.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Android 11 firmware for U has been added - build UA1.

No 11 for U1 yet, but I'm sure it'll be available soon, via the various firmware download tools like SamFirm and Frija
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Now available - build UA3

I own an AT&T Fold SM-F900U. Can I load a Samsung Universal firmware on it so wont need an AT&T simm chip to update Android thru FOTA ?
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
If AT&T is your carrier then the same FOTA rules will probably still apply while on U1 firmware. You'd likely have to insert a different carrier's SIM and trigger the carrier switch in order to successfully FOTA.

But you could try it and see what happens
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Bootloader 5 firmware (full firmware incl USERDATA) has been added to the OP link - build UF1.

U1 firmware also available via Frija and other various firmware tools
[Samsung Galaxy Fold Guides, News, & Discussion] theunf:
Thanks!

I read your post where says that no matter if I load an U or U1 firmware, it will work.

As I never did it in this model, can you point me a good guide for newbies and the latest files to download for the SM-F900U ?

I'm most interested to get rid of AT&T FOTA block eventually remove telco logo at boot, remove the "Your smartphone is initializing" messge and enable the eSIM app.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
If you want U firmware, the latest files were just posted 3 days ago

If you want U1 firmware, you can use Frija or another similar firmware tool
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
One UI 3.1.1 files were just added, for anyone who wants them!!! Build UHB
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Android 12 full firmware including AT&T USERDATA has been added - build UL9
[Samsung Galaxy Fold Guides, News, & Discussion] Judgenaut:
Ahhh!!

At&t totally screwed me by forcing an OTA while I was backing up.

Im stuck in recovery mode trying to install the proper OTA but I can't find the correct file.

RP1A.200720.012.F900USQU4EUBF is the message I saw, and it was supposed to be an upgrade from android 10 to 11.

Can I use another one to update without losing all my data?

Ive been at this for weeks..so lost
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
You can flash the same version that appears in Recovery, or higher - and yes, without losing data
[Samsung Galaxy Fold Guides, News, & Discussion] Judgenaut:
Amazing, tyvm.

Could I just ask which of the 18 firmware you have so kindly uploaded, would be "higher"? Or which would you recommend?

And lastly, when you say flash, do you mean using a separate tool or does the recovery mode OTA install option work? I am not rooted and afaik since im stuck in recovery mode, I am limited to the install/update options in recovery mode.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
1. I recommend whatever version currently shows in Recovery

2. Firmware flashing is done via Download mode, not via Recovery. Can you not get to Download mode?
[Samsung Galaxy Fold Guides, News, & Discussion] chhaggerty:
I just have one question. Does flashing the U1 software on the F900U AT&T fold create a device identical to a unlocked F900U1? Or in other words, is the hardware the same?
[Samsung Galaxy Fold Guides, News, & Discussion] cman6453:
Hardware is the same minus the unlocked SIM. Bloat is gone and ‘5G E’ is ‘LTE+’.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Hardware is identical. But remember that if it's still SIM locked to AT&T, it'll still only work on AT&T, even on U1 firmware
[Samsung Galaxy Fold Guides, News, & Discussion] avetny:
guys please can you help to download XAA-F900U1UEU1ASJ4.

download speed is so slow.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Then use SamFirm or Frija
[Samsung Galaxy Fold Guides, News, & Discussion] avetny:
Thank you i never heard about Frija, ill try that after work
[Samsung Galaxy Fold Guides, News, & Discussion] adidas123:
I have F900U. I flashed F900U1 and it works perfectly. Now, I'm thinking about flashing F900F firmware. Is it possible?
[Samsung Galaxy Fold Guides, News, & Discussion] hatran685:
I download u1 firmware already and i cant flash it.how do you do that?
[Samsung Galaxy Fold Guides, News, & Discussion] Latrell567:
Well Best Buy sells the unlocked version as I'm sure you may know, but it's not U1. It's U and the model number ends in XAA.
[Samsung Galaxy Fold Guides, News, & Discussion] super_Ken:
For the Fold SM-F900F

Hi everyone, I am a new member of the amazing XDA world.

Just bought the Samsung Fold SM-F900F in India. Surprising, while Samsung India's website states the phone supports both Nano SIM and eSIM. My phone has a grayed out eSIM IMEI on the about page under settings. I know with surety that its not carrier locked. So my question is, if I flash my phone with a firmware from sammobile from a different region such as France, Spain, Singapore, etc. Would it unlock the eSIM on my phone? At the moment, it doesn't even have the activiate mobile plan and other menu options required to add eSIM profiles.

Also, its been a while since I played around with android phones. Are the firmwares provided on SAMMOBILE stock versions?

Thank you. Felt amazing to write my first post/reply.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
This thread is only about the U and U1 models. Please post in a thread that is specifically about the F model, or create your own new thread
[Samsung Galaxy Fold Guides, News, & Discussion] bogdi1988:
Normally XAA means Samsung unlocked and those are usually U1
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
If I flash the u1 firmware but use the TMB (T-Moble I assume) userdata. Will I have a bloat free device but with T-Mobile Wifi calling and such?

---------- Post added at 09:42 PM ---------- Previous post was at 09:35 PM ----------

Okay so that failed. Flashing to u1 first and then to the u firmware with TMB package to see what that does.

---------- Post added at 10:00 PM ---------- Previous post was at 09:42 PM ----------

Was unable to flash the u1 firmware at all. Kept getting an SHA something error. Switched to the U firmware with the TMB userdata and it flashed. Hopefully thats a tmobile device because I want the tmobile features.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
SHA256 error means you're using the wrong Odin
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
3.13? Thats what I'm using, isn't that the latest?

---------- Post added at 10:06 PM ---------- Previous post was at 10:02 PM ----------

Sorry I have 3.13.3. Also flashing over the top of u1 with u1 and TMB userdata did nothing. I still have an ATT device. I need to flash the U firmware somehow.

---------- Post added at 10:14 PM ---------- Previous post was at 10:06 PM ----------

Yep SHA256 invalid. I tried 3 different downloads of Odin 3.13.3
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
You need the Patched version. It's been required for flashing ever since the S8
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
Sorry I don't keep up on this stuff. Anyway I got the patched Odin and it's flashing now.

Can you answer which package I should flash, u or u1 with the TMB user data, if I want to keep the most T-Mobile features in tact?
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
USERDATA goes with U, not U1. That's why it's in the U folder and that's why it says F900U in the file name.
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
Got it thanks. That's how I installed it and it's working good.
[Samsung Galaxy Fold Guides, News, & Discussion] Latrell567:
Hey I gotta question for you man. So basically here's what I did... I flashed my AT&T Galaxy Fold to the unlocked firmware, but after that I flashed it to the April T-Mobile firmware not knowing it was the April firmware. I don't remember what I did exactly, but it had something to do with me using the files from the August AT&T firmware, but using the T-Mobile USERDATA from April. Now whenever I try to re-flash the AT&T firmware on here, it never works, even with the AT&T USERDATA file. It flashes successfully, but then I get the same T-Mobile firmware. I don't want that anymore because the T-Mobile firmware will not update at all. I've been flashing files all day with no luck, and even the unlocked firmware still doesn't update from August, and I don't want to have to keep flashing new firmwares everytime there's an update. With the AT&T firmware files I used to flash that still has the T-Mobile firmware, it just shows in the settings under the Service provider SW ver. as:

SAOMC_SM-F900U_OYN_TMB_PP_0013

*my serial number*

then TMB/TMB,TMB/ATT
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
Just flash the unlocked firmware with no user data file and use the regular CSC file. Then flash everything back to ATT.
[Samsung Galaxy Fold Guides, News, & Discussion] Latrell567:
Ok so I made the mistake of flashing the unlocked November firmware, and now the AT&T one won't flash. I'm usually pretty good at this flashing stuff but not this time around. Is there anything I can do about that?
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
"Won't flash" isn't much info. More details would help.
[Samsung Galaxy Fold Guides, News, & Discussion] sniffy1029:
Hi i am having the same issue on the November, it is because it is on Binary 2 and the files on here are on Binary 1.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Binary 2 hasn't been released for the AT&T model yet. So you'll just have to wait.
[Samsung Galaxy Fold Guides, News, & Discussion] sniffy1029:
Missing calls on U1 on AT&T

Hi thanks. Do you know when the ATT binary 2 will be available or why I am missing calls on ATT with the U1 on November patch? Other than NO VOLTE which I didn't care but missing calls now.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Nope, no idea
[Samsung Galaxy Fold Guides, News, & Discussion] mdanish4:
Please forgive my ignorance..What binary 2 are you guys talking about? Is there another update after the last October update? I am on U1 firmware with TMB sim card and I have not received any OTA.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Probably hasn't been pushed out to you yet then. But you can get binary/bootloader 2 from SamFirm or Frija if you want it
[Samsung Galaxy Fold Guides, News, & Discussion] lakers6902:
Where can I find the latest firmware for the f900u1 fold? All I see is f900f
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
First page of this thread.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
I have no idea where you're seeing F900F. This thread is only for U and U1 models, and the links in the OP go to firmware for those specific models

My links do not have the absolute latest firmware for the U1 model. The newest/latest version can be freely obtained by anyone via SamFirm and/or Frija
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
Well samfirm doesnt have anything for the 900u actually, only the 900f.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
I'm aware. The other person inquired about U1, not U. That's why my response mentioned U1, not U.
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
Well as far as I can see samfirm has neither, you are the only place I could find anything u/u1 related.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
SamFirm absolutely has U1.

SM-F900U1

XAA

Auto

Check Update

Boom.
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
I'm an idiot. I was typing samfirm when I was referring to the website sammobile.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Ohhhh haha
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
Well Frija is amazing. I've never seen firmware download so fast. I have an issue with my Note 10+ though, I'll make a post over there.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Oh i know - SamFirm too! Samsung has phenomenal download servers :D
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
I tried to use samfirm, but the tool couldn't be downloaded, it redirects to a website with slow downloads.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
What are you talking about? All the different versions are still right here - https://xdaforums.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647

They all still download and run perfectly fine.
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
It says right there in giant letters "Note: This tool is deprecated. Please usefw.updato.com". I didnt think to download the tool and try it Haha.
[Samsung Galaxy Fold Guides, News, & Discussion] sniffy1029:
any update when Binary 2 will be avail for the AT&T model?
[Samsung Galaxy Fold Guides, News, & Discussion] adidas123:
Alright so my problem with ATT Fold is here. I was stuck with ATT software update when I use Tmobile network on my Fold. Since people know that if you use ATT device on another network like Tmobile or Verizon, you will never get software updates. Except using ATT sim card to do so. But then, I thought it would be possible to install U1 firmware and I would be able to use OTA update. Unfortunately, I'm still with ASJ4 with no OTA update yet. However, I check with Samfirm and U1 already has ASK1. So, it means that ATT device will never be able to update OTA on another network? Even U1 firmware? Or just because they still haven't released the ASK1 yet? ANy idea guys?
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
I'm confused too. My phone won't grab an OTA update even though I can see there are newer firmware files available. I have an ATT Fold flashed over to u1 with TMB userdata and CSC files. I have been messing with samfirm for an hour trying to understand how the firmware structure works. I was trying to download a U version (not U1) firmware and flash that with the TMB stuff hoping it would bring back OTA functions. It appears you can't even download U firmware from samfirm nor can you download any CSC outside of XAA. So the only place I can find the CSC/userdata files are in the beginning of this thread. I think.....
[Samsung Galaxy Fold Guides, News, & Discussion] adidas123:
If you use ATT Fold with TMobile network, you will NEVER be able to receive OTA. I guess the reason why I can't receive OTA is my device's IMEI. If Samsung detects ATT IMEI, it will not allow user to install U1 firmware, even you use U1 on ATT device. I think only manual update can help us right now. At least U1 is always available to download.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Yep, still works perfectly fine :) I've seen some users mention UPDATO but i've never actually looked into it.

You'd have to ask Samsung

I'm not sure how that works. I would think that U1 updates come only from Samsung, but maybe AT&T is part of the decision too. But at least we have the ability to manually update any time that we want :)

As long as you haven't updated to bootloader 2, then you can flash it to full TMB firmware, using the OP links (build SD4). But that build was going to be the initial release version back in the spring, before they decided to redesign it. So I can't say how it would run. AT&T is the only carrier that still decided they wanted it after the redesign, so there will never be anything but ATT and U1 firmware for the rest of that model's lifespan (unless one of the other carriers changes their mind I guess).
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
I must have the TMB firmware then. When I boot it shows a Tmobile splash screen and I have all Tmobile functions. Sounds like this is the end of the line for updates for me. If I flash over to U1 to get further updates, I'll lose my HD voice and all that. My software says U1 under settings though so I don't know what the hell is going on haha
[Samsung Galaxy Fold Guides, News, & Discussion] bogdi1988:
Could you keep the TMB user data but flash the latest SK1 from U1? SK1 does not have user data in odin so assuming it will keep TMB ones.
[Samsung Galaxy Fold Guides, News, & Discussion] seh6183:
I don't know I remember trying to flash carrier userdata files with international firmware and it never did anything, I just ended up with international firmware and no carrier functions.
[Samsung Galaxy Fold Guides, News, & Discussion] AtlanticFalcon:
I flashed to U1 from U....I was under the impression I would now get updates from Samsung OTA or via Smart Switch. Neither has happened. Says my software/firmware is up to date with a security patch date of August 1. What did I miss to get the updates?
[Samsung Galaxy Fold Guides, News, & Discussion] loudog3114:
Same story here... would love to have dex for pc working.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Well, good thing that anyone can manually install the newest/latest version any time that they want :)
[Samsung Galaxy Fold Guides, News, & Discussion] loudog3114:
From where? Nobody seems to have the firmwares for the SM-F900U1
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
You clearly haven't read the OP
[Samsung Galaxy Fold Guides, News, & Discussion] loudog3114:
I have, several times. I don't see any newer firmware than the SHA firmware for U1 that you posted in september. SamFirm does not have any firmware for f900u1 or u.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Uhhhhh, you really need to scroll back and read the posts from the 29th
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Bootloader 2 files for U model (build SK1) have been added. For those simply looking to update from existing AT&T firmware, I don't *think* it'll wipe if you use HOME CSC and skip USERDATA, but I can't promise it - you're responsible for backing up your data.

If anyone does that and it DOES wipe, please let me know, and i'll try to figure out why
[Samsung Galaxy Fold Guides, News, & Discussion] bogdi1988:
Wish we had userdata for TMB. Only one is Bootloader 1 and can't crossflassh if on SK1 now.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Correct. But even if you could, I have no idea if the phone would actually run on that firmware. It's entirely possible that Samsung changed something so that the gen 1 firmware can't be flashed on a gen 2 device, or won't run if you flash it, etc.

Has anyone tried doing that? Does it work?
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
Correct me if I'm worng here, I've been using TMB on ATT Fold (at U1), seems like Wifi calling is working well.
[Samsung Galaxy Fold Guides, News, & Discussion] redirish4u:
It went off without a hitch

I just did what was advised and now my fold is running the most up to date firmware. I am so happy that all that AT&T bloatware is gone. This was probably the easiest flash I have ever had to do, thank you for such a simple walkthrough.
[Samsung Galaxy Fold Guides, News, & Discussion] margo420:
Did you get the December update
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
Is there a way to flash ATT-U without the bloatwares?
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Uhhh, no. "U firmware without bloatware" is just U1 firmware
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
Haha, good point, I'm just trying to find a way to flash the December firmware from ATT without the bloats.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
You're not going to get bloat.

What Build are you currently running?
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
It's F900U1UES2ASK1. The only way for me to get the December update is to flash back to ATT U1 and then upgrade (with ATT bloats). No?
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
You're wayyyyy misunderstanding how this all works.

1. There is no such thing as "AT&T U1". U1 by definition has no bloat. Whenever you're talking about carrier firmware, it's U - not U1.

2. You're already running the latest/newest version of the U1 firmware. When the next update comes out, you should be notified to OTA to it
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
Haha. Excuse my typo. I meant ATT U. So as of right now, there is no way I can get the Dec. update without the bloats?
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
What "December update" are you talking about?
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
On ATT website: https://www.att.com/devicehowto/tutorial.html#!/stepbystep/id/stepbystep_KM1369613?make=Samsung&model=SamsungF900U

Does your current build not have Dex on PC?
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
Nope. Seems like the Dec. security patch brings it. :(
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
You could try skipping USERDATA when doing the U flash
[Samsung Galaxy Fold Guides, News, & Discussion] thientranduc199:
That's what I thought. Will let you know if I end up with a brick lol.

Does CSC contain all the goodies (well, the bloats)

Btw, thanks so much
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
You won't have a brick.

And no, USERDATA contains the bloat. That's why I recommended skipping it.
[Samsung Galaxy Fold Guides, News, & Discussion] lowrck:
i successfully flashed my att fold to u1 firmware. the links above didn't work for me, just kept erroring. i ended up using the frija program from another page on the forum to download sm-f900u1 firmware. works perfectly now on verizon.
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
The links themselves are fine. AFH being a free service means they they have issues from time to time. Any errors or failures are from the site itself - not from the links or files. Quebec seems to be the download mirror that can most be reliably counted on to be fast

I'm Having trouble Updating my phone to the December security patch I keep getting an error can some one help please
[Samsung Galaxy Fold Guides, News, & Discussion] iBowToAndroid:
Not without more information or details, no. "An error" is extremely vague
