So just put in an att Sim? And not make the Odin changes?
[Samsung Galaxy Z Fold3] iBowToAndroid:
You can't get those features without AT&T bloatware. (And even with bloatware, they still might not work, since you're not on AT&T service. This is just for testing, to see if it works).

And you can't get the bloatware unless your CSCs change.

The way to (try to) get the CSCs to change is to insert a SIM of the carrier whose bloat you want, and see if it prompts you to "reboot to apply new carrier settings"

So do that, and let me know what happens
[Samsung Galaxy Z Fold3] sllong:
I put my wife's ATT Sim card in, it restarted the phone. It now shows 5g which it did not before. It does allow wifi calling. It is now att/att/xaa
[Samsung Galaxy Z Fold3] sllong:
I put in my wife's ATT Sim in. It restarted the phone. The phone now showed 5G which it did not before, also allowed for wifi calling and it was ATT/ATT/xxa. I waited for a while then put the firstnet SIM back in and everything reverted back. Only shows LTE, no wifi calling, and XAA/XAA/XAA.
[Samsung Galaxy Z Fold3] bs3pro:
Then get an ATT sim.
[Samsung Galaxy Z Fold3] sllong:
So making the firmware changes described in this thread won't work?
[Samsung Galaxy Z Fold3] Flame Red:
FirstNet is different than Consumer and so your FirstNet (SIM) account may not have the same features.
[Samsung Galaxy Z Fold3] iBowToAndroid:
If you want AT&T bloatware, you'll get that if you pop an AT&T SIM back in so that it once again reads ATT/ATT/XAA, and then flash the full U firmware package including AT&T USERDATA
[Samsung Galaxy Z Fold3] clayton006:
So I may be confused on something. I got my verizon based z Fold 3 to flash U firmware with the ATT userdata that was provided under the U firmware link on the first post. I used odin to do the flashing. The phone rebooted, then I wiped cache. I booted up again and each time I still see the verizon splash screen and after completing the initial setup I see vzw/vzw/vzw. I do have a legitimate and active ATT sim card installed. Not sure if I missed a step, but odin said everything was fine with the flash.

I tried to click on your u1 firmware but there are no files under that.
[Samsung Galaxy Z Fold3] iBowToAndroid:
That's because anyone can get the files themselves at any time via the various firmware download tools like SamFirm and Frija. So I didn't bother downloading it, just to re-upload it again
[Samsung Galaxy Z Fold3] clayton006:
So I grabbed the U1, and then used your userdata for ATT. It looks like ATT is better on the device now as I can use my mobile hotspot, and it says mobile voice is LTE vs UMTS. The Service provide still says VZW/VZW/VZW. I can't seem to shake that.

When I did the above odin flash it told me that it could not boot android and I had to do a factory reset manually, and then it booted up.
[Samsung Galaxy Z Fold3] iBowToAndroid:
USERDATA is U, not U1. Flashing USERDATA along with U1 firmware can result in some pretty crazy and undesired results
[Samsung Galaxy Z Fold3] clayton006:
So I just tried to flash the U firmware with the ATT userdata you provided, and the Verizon splash screen showed up again. Now it is in a worse state than before because somehow it wants to go back to verizon.
[Samsung Galaxy Z Fold3] iBowToAndroid:
1. Flash U1 with no SIM inserted

2. Insert AT&T SIM and tap on popup to reboot

3. Flash U w/ AT&T USERDATA
[Samsung Galaxy Z Fold3] clayton006:
Will give it a try and let you know. Thanks!
[Samsung Galaxy Z Fold3] clayton006:
So I did the U1 flash with no sim, then it proceeded to start the phone setup, I inserted the sim card but had no prompt during initial setup. It did ask me to use my PIN to unlock the device (even though I removed my Samsung and Google accounts before the U1 flash).

I inserted the SIM and it has not asked me to reboot.
[Samsung Galaxy Z Fold3] clayton006:
It also says vzw/vzw/vzw as well before the reboot.
[Samsung Galaxy Z Fold3] iBowToAndroid:
If it still reads VZWx3 even after flashing U1, then it's not going to be possible to get AT&T bloatware because you need at least one of them to read ATT. You would need a U1 model sold directly by Samsung in order to be able to do that, because that one WILL change the CSCs when you insert a SIM
[Samsung Galaxy Z Fold3] clayton006:
Thanks anyway. At least this way my mobile hotspot and LTE mobile calls are working now with using the U firmware. Thanks for the write up and help.
[Samsung Galaxy Z Fold3] Zheigg:
Hey All,

Need some help here...trying to flash my T-Mobile Fold 3 with the U1 firmware, but I'm getting the following errors:

Any ideas?

Using:

Odin 3.14.4

OS Windows 11 Pro

Frija - It downloaded this:
[Samsung Galaxy Z Fold3] Zheigg:
Never mind...Found a patched version of Odin and it fixed things. Thanks anyways! I hope this helps someone!
[Samsung Galaxy Z Fold3] jemfalor:
possible to flash U1 firmware but with different region CSC from F926B for example?
[Samsung Galaxy Z Fold3] bs3pro:
NO.
[Samsung Galaxy Z Fold3] jemfalor:
so i have to flash the entire firmware including csc?
[Samsung Galaxy Z Fold3] Rick1221:
Hey, thinking of flashing the U1 firmware on my Tmobile z3, any improvements or features gained by the switch ?
[Samsung Galaxy Z Fold3] Zheigg:
Any time I can remove carrier bloatware, I see tons of performance on battery, mem and cpu usage, etc. You should do it @Rick1221!
[Samsung Galaxy Z Fold3] Pøîñtßlåñk:
Download links are dead.
[Samsung Galaxy Z Fold3] Rick1221:
How about 5g ? Are you getting any issue with 5g on t-mobile after the change ?
[Samsung Galaxy Z Fold3] bs3pro:
I came from tmo s21ultra to unlocked fold3 and see ZERO difference. I wouldn't worry about it.
[Samsung Galaxy Z Fold3] Zheigg:
You tell me. 🤣
[Samsung Galaxy Z Fold3] iBowToAndroid:
They most certainly are not
[Samsung Galaxy Z Fold3] iBowToAndroid:
That's not the definition of a "dead link".

I haven't uploaded any U1 firmware. Anyone can get it themselves via the various firmware download tools like SamFirm and Frija. So therefore there's no reason for me to download it, just to upload it again (and AFH works like crap half of the time anyway)
[Samsung Galaxy Z Fold3] mm60:
Have been trying to download the Verizon U firmware. First post says "Verizon (available via firmware download tools, but Manual Entry is required - Auto will not work)". Any idea if it is available. I just inserted my VZW sim into the phone and am waiting to boot. Will see if I can get the codes required to do the manual download. Thanks!
[Samsung Galaxy Z Fold3] iBowToAndroid:
Verizon MVNOs like Xfinity and Spectrum always get the same versions that VZW does - and you *can* pull firmware (via Auto) for those carriers in the various firmware tools like SamFirm and Frija. So you can use one of their CSCs/Regions to pull the firmware, and then copy/paste the versions into each respective field for Manual Entry, for VZW
[Samsung Galaxy Z Fold3] jones4765:
I have the unlocked fold and was able to get Verizon. It was a $3 charge to download, but did work and included the userdata file. https://samfirm.shop/samsung/firmware/445854
[Samsung Galaxy Z Fold3] mm60:
Thank you! Tried this yesterday and it worked like a charm! Used both the Verizon MVNOs (Xfinity and Spectrum) to look for the firmware on automated mode and was able to identify the 3 codes (PSC/CSA/PDA) required for manual download. Compared the values and they were the same (as a double check). I then looked for the Verizon firmware using Frija manual mode and the 3 codes from the MVNO's and found it. Downloaded using Frija. which unpacked the compressed file. I then inserted my Verizon SIM into the new phone, booted up with the original U1 (unlocked) software, it prompted me that it would restart to update the setting for my provider, did a quick setup and shut the phone down. Restarted in download mode and used the modified Odin to load the Verizon U software including user data for the Verizon bloat. After the firmware loaded, the phone did not boot up but gave me the option to clear the user settings. I did so and booted into the Verizon U firmware. Was able to copy over all data using Smart Switch and the phone is working perfectly. Thanks for the guidance!
[Samsung Galaxy Z Fold3] iBowToAndroid:
When I say "SamFirm", I'm not referring to a paid website. Anyone can get the firmware themselves for free, via the various firmware download tools (I'm talking about a computer program, not a website). But hey, at least you got it :)

You're welcome
[Samsung Galaxy Z Fold3] Who-Lep:
I purchases carrier locked through ATT(U). I flashed U1(XAA -AP, BL, CP, & CS) to remove bloatware & booted fine. But, version still said ATT/ATT/ATT/(not a problem because bootloader & device is locked?). If I want to revert to "stock" ATT, I would flash U with AP, BL, CP, CS, & USERDATA together?

Thanks,

Julio
[Samsung Galaxy Z Fold3] Who-Lep:
Thanks!
[Samsung Galaxy Z Fold3] x.Orville.x:
I can find any unlocked firmware via samfirm any one can help me? I downloaded one but it's from thom brow edition
[Samsung Galaxy Z Fold3] iBowToAndroid:
You need to make sure the CSC is OYM, not OYN
[Samsung Galaxy Z Fold3] x.Orville.x:
I need to put on samfirm CSC OYM and phone model ? Searching i find this one

F926U1TBU1AUGB 11 4File | Easy Firmware

[Samsung Galaxy Z Fold3] bs3pro:
Anyone think it's odd that only the exy got the Sept update??
[Samsung Galaxy Z Fold3] iBowToAndroid:
This is your problem: F926U1TBU1AUGB

TBU = Thom Browne edition.

For regular U1 firmware, you need this: F926U1OYM1AUGB
[Samsung Galaxy Z Fold3] Osimma:
question: i've successfully flashed U1 firmware on my verizon fold 3 but how does updating work? will my phone get unlocked updates OTA or will it get verizon firmware updates? i really don't want any verizon sw on my device if i can help it, trying to maximize battery life.
[Samsung Galaxy Z Fold3] iBowToAndroid:
If you've flashed U1, then you'll get U1 updates.

Bloatware doesn't usually make any noticeable difference in battery. For the most part, if you're not using it, it's not using battery
[Samsung Galaxy Z Fold3] Osimma:
awesome! ty for the reply. one of the biggest things i hated with the verizon bloatware was the bootup animation, it turns both screens on max brightness with a bright white background. i swear booting up would use like 5% of the battery is was insaneeee.

even though i didn't use any of it and disable a lot of them, i still noticed that a few verizon things would still run in the background every now and then, or get loaded into ram somehow. even if its a small battery gain, i'll take what i can get, every little bit adds up. i'll also be removing some Samsung apps/features i don't use with adb commands
[Samsung Galaxy Z Fold3] Kenkool12:
I came from from the oneplus 9 pro. I can flash my carrier Locked att fold 3 and get updates directly from samsung without bootloader or sim unlock.
[Samsung Galaxy Z Fold3] apristel:
Anyone have issues with Frija stopping while downloading? I get about 1/2 way through the SM-F926U1 / XAA download and it stops.... Ideas?
[Samsung Galaxy Z Fold3] iBowToAndroid:
Maybe post in the Frija thread...?
[Samsung Galaxy Z Fold3] Rylin210:
Hmm, I currently have a T-mobile fold 3.

Any evidence of improved battery by switching to stock?
[Samsung Galaxy Z Fold3] Kenkool12:
Can I flash my carrier locked fold 3 on att without unlocking the bootloader or being sim unlocked.
[Samsung Galaxy Z Fold3] rsfinsrq:
So I just received my carrier locked T-Mobile Fold 3 and while going through the settings I noticed my service provider software version reads TMB/TMB/XAU/TMB. I thought it odd that there was a XAU mixed in there. I checked my Note 20 Ultra and it reflects TMB/TMB/TMB/TMB. I downloaded the software from Frija for SM-F926U for CSC TMB and the userdata in the file reflects USERDATA_XAU_F926USQU1AUI4. The Note 20 Ultra Frija download identifies the userdata as TMB. Also, when I first received my Fold 3, I swapped the sim card from the Note 20 into the Fold 3 and went through the setup. I wasn't until I had went through the process I noticed no cell data and emergency calls only. I later found out the my sim card was deactivated when I transferred to e-sim on my Note 20. Not sure if this may have resulted in the XAU or if it's supposed to that way. I went to my T-Mobile store and got a new sim card and everything seems to be working fine, just that XAU is still listed in the software version. Any insight would be appreciated.
[Samsung Galaxy Z Fold3] pilotp94:
Does anyone know if the 926W (Canada) model can also be flashed to U1 firmware? I know this was previously possible with the S8+, S10+, and potentially other models too, don't imagine Sammy would change things up now, but I'm gonna be waiting at least a month for my order to ship so I can't test for myself atm.
[Samsung Galaxy Z Fold3] Acoustichayes:
Active CSC/SIM 1/Region/Primary CSC​

​

Basically saying the initial region of the current installed firmware is XAU. Which I'm assuming is similar to xaa/xas meaning unbranded because XAU has no records anywhere 👀.​

I believe it's the designation for multi CSC firmwares
[Samsung Galaxy Z Fold3] rsfinsrq:
Thanks for the reply! This makes sense. I guess having the XAU in my service provider version may be due to setting up the device with a deactivated sim. If anyone with a T-Mobile locked F926U device could verify weather or not they have the XAU in service provider version (see screenshot) it would be greatly appreciated! Trying to avoid resetting my device to find out (y)
[Samsung Galaxy Z Fold3] Acoustichayes:
Actually, I have xau as well.

My phone was set up at t-mobile, but they had to get me a 5g Sim card because my previous phone only had LTE.

I'm 99% sure the XAU just means it's a multi CSC firmware that doesn't set a specific region when firmware is flashed. Instead using the Sim to check region for Ota updates.

Which as you said could be due to being set up without a Sim card, but also could be just how the fold 3 is if it's a universal CSC partition. That would require someone to chime in that had a proper Sim card in the phone during setup.

Normally a phone pings Samsung's servers when booting after firmware flash and sets the region to whatever server location is closest, as well as inferring carrier specific CSC from that region.

That generally would mean that you couldn't get Ota updates from someplace that isn't your region. (say you were overseas)
[Samsung Galaxy Z Fold3] rsfinsrq:
Thanks for your reply! I think as long as there was a T-Mobile sim, regardless of 4 or 5G, I believe it would identify the sim and set up properly. That being said, I feel comfortable that our service provider version is in fact correct. Unless someone chimes in with something different, I'll hold off on resetting my device. Thanks again!
[Samsung Galaxy Z Fold3] Acoustichayes:
Right that's what I'm saying. Region is only set for Ota update purposes. The xxx/xxx/xxx/TMB is what says to set it up as a t-mobile device from initial boot if no Sim is present.

The region being XAU(instead of TMB) is solely saying you can still get Ota updates regardless what region you are in
[Samsung Galaxy Z Fold3] iBowToAndroid:
Yes

Yes
[Samsung Galaxy Z Fold3] Hero_is_Over:
Tbis is completely incorrect. Carrier bloat will run in the bc kground without your knowledge. Typically it is software used by the carrier to "optimize your data speeds by reporting your triangulated location incessantly. Even worse some carriers like ATT have apps like "MobileServices" which will actively install bloatware. These are two examples, but to say bloat doesnt hurt battery is the wrong message to tell others. It will also cause slowdowns and other miscellaneous issues.
[Samsung Galaxy Z Fold3] iBowToAndroid:
We'll all wait on pins and needles for a comprehensive detailed report by you, showing proof of this
[Samsung Galaxy Z Fold3] tyrone1:
My unlocked t mobile z fold 3 says tmb/tmb/xau after I flagged u1 csc tmb firmware.

There is no 4th tmb. Why?
[Samsung Galaxy Z Fold3] Markeee:
Is it possible to re-flash and use an International Dual sim variant of the Fold 3 here in the US on Xfinity Mobile?

I know for fact that Xfinity Mobile does not support dual or eSims so i would use another carrier for the second number
[Samsung Galaxy Z Fold3] iBowToAndroid:
Reflash? No.

Use it as is? I don't know for sure but probably not. My guess would be that if you typed the IMEI into Xfinity's BYOD checker, they would say it's not compatible with them
[Samsung Galaxy Z Fold3] Markeee:
There BYOD compatibly checker is pretty useless it only allows you to check for Pixel Apple and Samsung phones. I been running a Nexus 6 with LineageOS that shows up as not compatible for years. many other phones work also.

I guess what I'm asking is isn't there a way to just simply flash one of the US firmware's like XAA = U1 firmware or the CCT = Xfinity to enable the proper US frequency bands on a Physical dual sim international phone ?
[Samsung Galaxy Z Fold3] iBowToAndroid:
Nope. If you want US firmware, get a US phone
[Samsung Galaxy Z Fold3] Markeee:
Just snagged a Fold 3 Samsung version SM-F926U1 off Swappa https://swappa.com/listing/view/LVLI62772

if its already running the latest firmware Is there any added debloat or other benefits to flashing XAA = U1 firmware. My carrier is Xfinity Mobile also wondering if there's anything in particular to Xfinity I need to know before I start flashing it ?
[Samsung Galaxy Z Fold3] Mr. Orange 645:
If just a U1, which it is listed as such in that listing, then it's already running the XAA U1 firmware. Just pop in your SIM card and enjoy.
[Samsung Galaxy Z Fold3] Markeee:
Yeah that's what I though Thanks

It's been a min since I flashed firmware I have a T-Mobile Fold 3 trying to go to stock Samsung what do I need to flash.

I've got the u1 firm I'm gonna odin to my Verizon u..Was wondering in odin do I do the user data thing too..Read on another not to do it so I wanted to check
[Samsung Galaxy Z Fold3] zimgir124:
U1 Firmware XAA shouldn't have a USERDATA file on it, so you can just ignore that slot on ODIN.
[Samsung Galaxy Z Fold3] snyperstyle:
Stupid question. If I flash xaa firmware will that sim unlock my phone?
[Samsung Galaxy Z Fold3] durag5:
Anyone able to upload the files again? it looks like U is missing and U1 USERDATA missing all but ATT.
[Samsung Galaxy Z Fold3] cfish81:
Hi guys. Been a few years since I've been on here.

My question is can I use a Tmobile version and flash it for Verizon?

Will everything function as a normal Verizon fold 3?

Buying used and tmobile is everywhere cheap. Unlocked and Verizon still high priced. Found phone and the watch 4 classic 46mm for $1000

This question maybe answered somewhere already, sorry if I missed it and thanks for your help!
[Samsung Galaxy Z Fold3] SleepyCat420:
Hi all! This is like my 2nd time flashing firmware(from att to u1) and it seems a bit different than the last time. I enlisted my brother's help, and it seems to have gone through successfully, but I'm worried as he said it would do the wipes and resets automatically, but my fold booted up with all my data still. I haven't found anything not working and it shoes as u1, but I am wondering if there are gonna be issues and what steps I should take? (Like reset and flash again or just factory reset?) And would it be bad to restore from my smartswitch backup on the u1? Thanks all!!
[Samsung Galaxy Z Fold3] Markeee:
I was wondering the same thing from what I understand after reading the first post in this thread seems all US carriers F926U versions along with the F926U1 version that Samsung sells the are basically the same phone and are all 100% interchangeable.

Best to read it yourself I'm a bit on the ADD side when it comes to reading and comprehending details
[Samsung Galaxy Z Fold3] cfish81:
For sure thanks for clarifying. I've been out of the game since the really old Note days when we had full unlocks and all the fun stuff.

I saw someone else mentioned the files op posted not all are there? I looked and see only one. I think that's why op said to use winrar or similar to unzip the files. Guessing they are all packed in there? I'm going to be looking for the Verizon stuff to get my visual voice mail working etc. And do away with the pink screen on boot lol. Wonder if these Verizon phone only apps will work on the unlocked version? Would be nice to do away with much of the bloat ware.

Want to get all my ducks in a row and send it hopefully only once
[Samsung Galaxy Z Fold3] Markeee:
I'm on a unlocked F926U1 Samsung version using Xfinity mobile which runs off Verizon network they have there own visual voice mail app that actually works pretty good. Working Visual voice mail is pretty important to me also
[Samsung Galaxy Z Fold3] martinisadork:
Quick question, Verizon disabled the samsung blockchain keystore on these phones for some reason.

Will flashing the U1 restore this functionality?

Also, is there anything lost, other than bloat, by doing this?
[Samsung Galaxy Z Fold3] Roosterkid:
Mirror links https://galaxyfirmware.com/model/SM-F926U1/
[Samsung Galaxy Z Fold3] martinisadork:
I'll reply to myself as I tested it out: Flashing U1 without factory reset and without USERDATA keeps all verizon bloat but unlocks the blockchain keystore.

Thanks OP! Two questions:

1, I have a ATT variant (F926U), I want to flash an unlocked firmware to get rid of bloatware, should I just pick up the XAA variant firmware and don't need to care about PDA number? For example I can flash any firmware in this link? https://www.sammobile.com/samsung/galaxy-z-fold-3/firmware/SM-F926U1/XAA/#SM-F926U1

[Samsung Galaxy Z Fold3] supersonic64126:
So I've read through this thread completely probably 3 times already. I'm not sure what I'm missing. Trying to flash my Z Fold3 T-Mobile to Verizon U firmware. I've flashed Verizon firmware including CSC and User Data after inserting Verizon sim card. I've flashed U1 and tried inserting Verizon sim and rebooting to force the TMB to change to VZW. It doesn't. Every time I flash the VZW U firmware with UserData I get the T-Mobile boot screen after a successful flash, T-Mobile bloatware PLUS Verizon bloatware. I'm so confused, what am I doing wrong? Yes phone is sim unlocked.
[Samsung Galaxy Z Fold3] Markeee:
I just flash the XAA = U1 firmware and include the normal CFC not the home CFC that will wipe reset your phone clean. I don't worry about user data leave it empty when I pop my sim in after that loads the user data I use the patched Odin3 v3.14.1_3B_PatcheD https://xdaforums.com/t/patched-odin-3-13-1.3762572/

I'm on Xfinity Mobile which runs off VRZ and I get a pretty bloat free install with no carrier boot screen. I'm on the SM-F926U1 Samsung unlocked version but from the way i read this post there interchangeable U and U1
