F700U AT&T Firmware Links and General F700U/F700U1 Firmware Discussion - Samsung Galaxy Z Flip Guides, News, & Discussion

For those who aren't already aware, F700U is the model number of all of the US carrier versions of the Galaxy Z Flip. The F700U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
Manual Odin flashing is designed for those who:
- want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
- want to flash U1 firmware to their U device
- want to convert from U1 firmware to carrier U firmware
- want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)
For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via several tools like SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm/Frija.
This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware, I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.
Happy flashing!

U1 firmware: https://www.androidfilehost.com/?w=files&flid=305568
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have lots of threads just like this one for other Samsung flagships, if it interests you.
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data
- Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T (and Cricket, if they get this model). I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For identifying USERDATAS, and to know what region/CSC to use in SamFirm/Frija:
ATT = AT&T (not available via SamFirm/Frija)
CCT = Xfinity Mobile (Comcast)
CHA = Spectrum Mobile (Charter)
SPR = Sprint
TMB = T-Mobile
USC = US Cellular
VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
XAA = U1 firmware
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want

Or you can use SamFirm and Frija, which are free and don't involve a 3rd party website loaded with ads and Captchas and other crap

i use frija and samfirm already , but they only provide latest firmware , not previous firmwares, also samfw is free and not slowed down like sammobile or samfrew.

Yes, but like Mega, it downloads the file into RAM first, before converting it to storage space. So anyone with a PC that has less than 8 GB of RAM can't really use that site

No idea - you'll have to try it and see. Make sure it's SIM unlocked first

So if I have the unlocked version, I can flash the ATT userdata and get VoLTE with my ATT SIM?

Bootloader 2 updates are rolling out - both Sprint and AT&T are both getting build TG1. It's already up on SamFirm and Frija for Sprint, and I'll add the AT&T USERDATA as soon as I get it.
To add another option, I'm also adding all of the files for the last bootloader 1 update - TF1 - and its AT&T USERDATA. Those files are now uploaded to the OP links

---

Do you by any chance have an ETA as to when you can get the AT&T TG1 USERDATA?

Hi guys, I got a F700U/DS Z Flip, but I figured out that the national model that is being sold back at my country is the F700F, I wanna use my country's Samsung Pay cards, so does anyone know if it's safe to flash the F700F Firmware on a F700U/DS ?

It's not possible to cross-flash those 2 models

Thanks to everyone in this thread for pointing me in the right direction.
I wanted to drop by and say I was risky/dumb enough to try converting the phone from the AT&T branded firmware to the Samsung unlocked/unbranded firmware and I was successful.
The reason I did this was because I had terrible service with Verizon on the at&t firmware. I tried everything. The phone refused to detect band 13, Verizon main band despite it being the strongest at my house (I know from other devices). The AT&T firmware solely connected to band 66.
Anyway, I used patched Odin to flash the unbranded (SM-F700U1, Region XXA). It booted up without the AT&T branding, rebooted once it sensed my Verizon sim, has no AT&T bloat, and connects to all of Verizon bands.
Service is great now. And the unbranded firmware is so much snappier somehow.
Anyway, thanks again yall. Hope this helps someone..

@SilentAce07 This is perfect! Thanks for updating us. I want to use an unlocked Z-Flip, originally with AT&T, on T-Mobile. I don't want to deal with all the AT&T Bloatware or the chance that it's somehow customized to prefer a certain band over another, etc. I'd rather go generic. So I wanted to flash the U1 firmware onto this U device. Where did you get the firmware from? One person linked to samfw.com/firmware/SM-F700U1 but that doesn't exist (404 not found). I found my way to samfrew.com/model/SM-F700U1/region/XAA/ but I see 2 different ones released July 31st, I don't know if I want the TB or the EU version (F700U1TBU2BTGE vs F700U1UEU2BTGE).
I've used a patched Odin before to convert a Verizon Galaxy S20 Ultra 5G over to Generic and then to T-Mobile, so I'm generally familiar with the procedure, but it was easier to find the U1 firmware for the S20 Ultra 5G than it's been for this Z-Flip/F700.

Hi iBowToAndroid, I've got nothing but mad respect for you and your posts. One of your other posts seriously helped me get my Galaxy S20 Ultra 5G unbranded. This is a great service you do for us and it's much appreciated. With the Galaxy S20 Ultra 5G though you were kind enough to upload the generic U1 firmware to AndroidFileHost as well, so I was able to get the firmware for that one from AFH. But I understand that for this phone (Z-Flip / F700) you chose to just upload the AT&T specific version since AT&T doesn't allow their firmware on other websites, again, much appreciated. But this left me searching for where to get the U1/XAA generic unbranded firmware. Your first post mentioned Frija and SamFirm...
1. I tried to use Frija but I've searched for Model SM-F700 / SM-F700U /SM-F700U1 / F700 / F700U / F700U1 with the CSC of XAA and each and everytime I got the error "Error 102: Unable to find firmware for ..."
Maybe you could help point Frija users to exactly what to put in for Model and CSC? Just let us know what to search for / input into Frija and we could use that.
2. You also mentioned SamFirm also has it. But a quick google search for SamFirm brings you to https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 and the very first thing you see is "This tool is deprecated. Please use fw.updato.com" so it seems like SamFirm is no longer being supported, but I went to the website fw.updato.com as mentioned and the only phone they have is the SM-F700F (international version). They don't have the SM-F700U or U1 that I could see.
So I was at a loss where to get the U1 firmware.
---
Then the first has a link to: www.samfw.com/firmware/SM-F700U1 but that results in a 404 not found. So samfw seemed to be a bust.
The first comment also has a link the (samfrew) website: samfrew.com/model/SM-F700U1/region/ATT/ which is confusing because it has "U1" but also ATT; I thought U was for AT&T (and other US carriers) and U1 was generic. But either way, I found my way to samfrew.com/model/SM-F700U1/region/XAA/ which is consistent with your first post about using U1 and XAA in conjunction for generic. Great! But then I didn't know the difference between F700U1TBU2BTGE vs F700U1UEU2BTGE both have the same date. So that's why I posted here, trying to get some clarification on just which one to download.
HOWEVER, to help others, I found on sammobile that I could select the U1 firmware, and odd enough I could select "USA (T-Mobile) (TMB)" as the country, which again confuses me because U1 is supposed to be generic, not carrier specific; and it's more odd because there is no T-Mobile version of this phone. But I noticed sammobile then poinmted me towards "F700U1UEU2BTGE" (UE firmware) so that kind of helped make my decision for me. I chose to download F700U1UEU2BTGE from samfrew.com and I flashed it with a patched Odin and it took. The phone booted up, generic, and seems to work just fine. No AT&T or any other carrier, bloatware.
tldr; So for future people searching, if you want to change it from an AT&T branded/specific model to something Generic, go to the website samfrew.com/model/SM-F700U1/region/XAA/ and grab the latest UE image.

Again, no disrespect intended iBowToAndroid, I absolutely did my leg work before posting. I tried my very best to find it elsewhere and through various searches. I wasn't just lazy and immediately asking for help like some others tend to do.

SamFirm and Frija both still work perfectly fine, and both pull F700U1 firmware perfectly fine. Literally just verified it on my own computer
