Hi. I have a Galaxy s21 from EE with EVR firmware (EE firmware) and I’ve tried flashing BTU and other UK networks firmware on it using Odin but that doesn’t work. Every time Odin says it’s passed, it hasn’t changed the firmware at all and I’m still stuck on EVR. I’ve tried SamKEY but it’s saying it doesn’t support my firmware (G991BXXU3AUGM) so I’m not sure what to do.
Any help would be appreciated. Thanks.
I have a US S21 but am also in the same boat, and sadly I think the only way at current is to wait for SamKey or to downgrade to a firmware that'll support SamKey.
I've tried ODIN flashing my US TMB S21 to try and get it working on AT&T fully many times over, but the CSC is locked up tight and SamKey was the only way to get it done for me. (Sadly, my CSC reverted when I stuck another TMB SIM into the phone and it locked the CSCs again so I have to pay for SamKey a second time if I want my AT&T SIM to work fully again. Yaaaaay.)
Samsung really needs to hurry it up with the auto-config firmware for the S21s.
I haven’t got a clue on how to downgrade it, any idea how?

(Sorry for the delay, yesterday got busy.)
For downgrading you'd just need ODIN and the desired firmware to downgrade to, just making sure the binary version matches (in this case, the binary version is the first number of the last 5 characters of the software version. So in the case of G991BXXU3AUGM, you'd be looking at "3AUGM" and in that case, your binary version is 3. So you can flash any firmware that's 3XXXX). At least that's how it is on Snapdragon models.
If you've no idea how to work ODIN it might be worth it to just wait. Plus, downgrading would incur a factory wipe (and restore with Smart Switch, which doesn't necessarily restore all settings and such.)

HK is very likely Exynos, so no. You can generally flash software from other variants so long as the CPU matches (most of NA uses Snapdragon, for example. You can't flash Exynos firmware onto a Snapdragon S21.)

Is this easy enough to do. Got the chance of buying one at £400 but would need to unlock it and preferably have it unbranded.
Is the unlocking part something I could do myself or would I need to take it to a vendor and how much would it cost?
Thanks.
The 3 phones are unlocked already
It costs £10 on ebay for an unlock code
Easy enough to un brand by flashing a stock firmware .
But i would wait until i had a copy of my original firmware first in case of claiming on 3 warranty .

Mine is on Three and unlocked/unbranded (although I did get it via Carphone Warehouse) so your mileage may vary.
R.
I had a 3 UK phone, I got it since the launch, as I had it pre-ordered, and it arrived locked, however I used the Voodoo SGS III Unlock Tool and it worked brilliantly, it is free to download and it unlocks it almost instantly, however ROOT is required.
For the information of anyone reading this thread, in branding is as simple as flashing a generic official rom from your country via Odin, takes 5 minutes.
Unlocking is done via the methods shown here in the forum and is free, again, takes 5 to 10 minutes.
To undo the changes, flash back to the carrier ROM you had originally, and I wouldn't worry about undoing the unlock.

Use supercurio's galaxy s3 unlock tool from market,its free
Could anybody with a more in-depth knowledge care to offer a bit more info on this?
I currently have an O2 branded S3.
I have rooted this (when I first got it) and that went fine (Odin, I think was the method I used).
If I wanted to flash a basic unbranded image on this, would I use the very first post from this thread, labelled "I9300XXBLFB"
http://forum.xda-developers.com/showthread.php?t=1646610 (If not, could somebody point me towards the correct file please?)
Then, If I ever needed to put an O2 image back onto it, (maybe for warranty purposes) could somebody point out where I would find the O2 branded one, as I can only see an Orange branded one in the following post?
Also, is there actually much risk involved in the flashing, or would I be really unlucky for anything to go wrong?
(P.S. I've seen the thread about how to change the handset back to make it seem that it's never been flashed/modified, so I realise I'd need to do more than just flash the O2 image back onto it. Hopefully, I'd never need to anyway).

1st of all dial *#1234# into the dialer this will give you the current firmware version(im assuming your still on o2 firmware and havent changed it yet) then go to here
http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9300&r=1#regiona
this is s3 firmware version for europe and find the firmware that matches the 02 version your on. This is your fallback incase you need to warranty repair the phone or you maybe have a flash problem with unbranded at least you have the o2 to fallback on.
Ill assume its more than likely this one
http://www.sammobile.com/firmware/?page=8&view=4650
and heres the dl link for it
http://www.hotfile.com/dl/157417303/f25aa83/I9300XXALE8_I9300O2UALE5_O2U.zip.html
Then as youve already mentioned flash the LFB version, here ya go dl link
http://www.hotfile.com/dl/162402398/abc9bdb/I9300XXBLFB_I9300OXABLFB_BTU.zip.html
Now if you want any other versions of official firmware you will need to join sammobile to be able to dl them
Thanks very much for the reply.
A couple of issues having taken a look at those links.
The first link doesn't seem to have my firmware listed - some are close, but none the same.
Mine shows: AP: I9300XXALEF, CP: I9300BWLE6, CSC: I9300O2UIALE7
Would an alternative work if I ever needed to flash back? (maybe the one you've linked in the 2nd link?
And, finally, to confirm - the last link - "LFB" (not sure what that means) - is that the unbranded rom that I'd be looking for?
Many thanks for the advice.

Have your tried updating through kies 1st? As far as im aware you will still get o2 updates through it. I noticed my phone out the box(unbranded) didnt have firmware matching this list either but after a kies update I was on firmware more well known for the region and was on the list.
Yes the LFB is the latest unbranded firmware.
edit:- doing a bit of research it seems o2 branded phones are running the LE8/LE5/LE5 software so i think your missing an official update.
I've not really used Kies as yet. I'm running Mountain Lion on my iMac, & Kies won't install on that.
I can always use my lappy at work tomorrow to look into it.
If I was going to change to the unbranded firmware, I assume there's not really any point in using Kies to update the official O2 version on here at the moment?

Kies is, as you say available for Mac, but won't yet run on Mountain Lion. I'm assuming they'll update it soon.
You were right, Kies did update my O2 branded handset to the latest FW, which does show on SamMobile's site.
Phones from the three network are locked, carphone warehouse phones are unlocked as they're from the suplier.
Theres a tool called voodoo i beleive it's used for unlocking the sim on samsung phones, you should give that a whirl.
It's available on the market.

Root your phone and nand back up your rom.
Keep the back up on your computer.
Flash whatever you want and use the nand back up to restore if you need to.
Remove root and reset counter using triangle away if you ever need to send it back.
I apologize if this is a stupid question since there are several threads about flashing different firmware.. Having not had a Samsung phone since S7 Edge, the process seems to have changed a bit. I bought a Verizon S9+ from a family member for cheap and I'm currently a subscriber on T-mobile. I'd like to flash over to the T-mobile firmware.
Current Baseband is G965USQU1ARB6
I believe this means that I'm on the v1 bootloader.
My understanding is I need to flash to the U1/unlocked firmware without a SIM and then flash to the T-mobile firmware after that. Correct?
Any rationale to picking a specific firmware since it appears there have been several updates since my current one? I assume once I get T-mobile on there I would get OTA updates via T-mobile from then on, correct?
Also, when I switch to T-mobile will I be able to get on the 600 Mhz Band 71 for T-mobile's LTE or are the radios actually different in the different carrier versions of the phone?
Thanks in advance for any help, and I'm sorry again if this is a stupid question - just having a hard time with the changes in firmware flashing that occurred after S8 came out apparently ://
The radios are identical between all U and U1 models, but the firmware isn't. You will find a Verizon phone won't work on TMB without flashing for several reasons (wrong APN which isn't editable, for one).
The latest U1 build is ARF4. That's also available as a U build for TMB. Flash to the U1 then to U. Use normal CSC so it will factory reset both times. You'll be golden.
If you want to be able to switch again, I recommend you block any updates TMB pushes once you're back on U, as newer U builds update the bootloader and you won't be able to flash back to U1 until it gets updated.
Good luck.

Thanks for the reply! I flashed the U1 firmware and used normal CSC to factory reset. Then I flashed the TMB one. When I boot up it still says Verizon and the software version says VZW/VZW/VZW still. Should I have inserted the TMB sim prior to the second flash? Did I hose myself now that I've flashed the latest version and its still VZW? Thanks

If you took TMBs newest OTA, you're screwed. You'll have to wait for an updated U1 build. No one knows when that may arrive.
I recently got an unlocked galaxy s9+ (sm-g965u1) and i like to at least have the latest firmware on hand incase i need to flash it. sammobile has multiple firmware files available to download. seem to be carrier specific. what would happen if i flashed one that says, say, AT&T? currently it has no carrier apps built in.

Far as I know it would just have the all the carrier specific apps and what ever little carrier additions the firmware has that the U1 firmware didn't. Granted I have the Sprint S9+ but if I go from the Sprint firmware, to U1 firmware and back to Sprint firmware and that's what happens.
Though what I have been using for the unlocked firmware is at the link below. If you download any of the supplied G965U1 firmwares from the tutorials on the forum it's the XAA firmware.

Thank you. I ended trying a U firmware and got the att apps. been a long time since ive used android on an everyday basis.
For those who don't know, F900U is the model number of all of the US carrier versions of the Galaxy Fold. The F900U1 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. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. 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 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 AT&T doesn't allow their firmware to be publicly available (for any of their devices). I pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, and also gets me access to AT&T firmware, 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. I'll definitely do at least one build per bootloader level though.
This is not a "beginner's guide to Odin flashing"-type post/thread, so I won't list basic, step-by-step 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 the "beginner's" posts/threads - there are tons of them here on XDA.
U firmware: https://www.androidfilehost.com/?w=files&flid=293117
U1 firmware: https://www.androidfilehost.com/?w=files&flid=293118
Happy flashing!
Notes:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I compress 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 Android File Host folders is: build - bootloader - Android version.
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and 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.
- I pay for a subscription to a site that gets beta builds and also sometimes gets the official releases before they hit SamFirm, so that's where any of my files come from. I will only be posting versions that I get early access to, and USERDATAs that aren't available on SamFirm or Frija (AT&T). The newest/latest firmware files for all carriers other than AT&T can always be obtained via SamFirm and Frija.
- For USERDATAs (all the others are self explanatory):
AIO = Cricket
CCT = Xfinity Mobile (Comcast)
CHA - Spectrum Mobile (Charter)
TMK = Metro PCS
- 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
Interesting development, as we approach the release date for the now-redesigned Fold: U1 firmware has appeared!
I have no idea if they were planning for a U1 model all along, but that firmware never showed up earlier this year. I still haven't seen any new U firmware, but assuming that I get access to at least the launch version before the actual release, I'll post it when I get it
Build SH9 has appeared for the U model, along with an AT&T USERDATA. Files have been uploaded to the OP link

I don't understand your question.
First of all, numbers come before letters. 9 is older than A. If SH9 and SHA were both released for the same model, then SH9 would come first, and then there would be an OTA to SHA.
But SH9 is U firmware and SHA is U1. You can't OTA to a different model's firmware.

It's impossible to brick it. And yes, there are tons of very precise and exact Odin flashing guides here on XDA. Odin flashing is always pretty much the same process, no matter the model. Put the phone in Download, make sure you have the right Odin version, extract the zip, load all the files, plug the phone in, and click Start
What is the site you pay a subscription for?
I have a small question... will I brick the Fold, if I flash this to the Korean Version of the Fold (SM-F907N)?
The only version I could buy in where I live is the Korean version, which is a 5G model, but I really want to use my credit cards from USA. I guess I have to have a Fold with USA firmware to use Samsung Pay with credit card from USA, but I don't know what would happen if I flash this firmware... I am okay with losing the 5G, I just want the Samsung Pay works with my credit cards...

You can't flash it. Odin won't allow you to, because those models are not cross compatible. If you want a Fold that does US Samsung Pay, buy one from the US and have it shipped to you

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!
U firmware: https://www.androidfilehost.com/?w=files&flid=305567
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
it's already available on samfrew and samfw if needed.

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?

Did this ever work?
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
