Hi guys just got a new phone supposed to be uk unlocked sim free brand new.but its weird
The service provider sw ver dont look english to me
SPR/XAA/VZW
I have my ee sim card inserted and it works to make calls. But there is a weird notification saying OMADM activation not completed
Also says LTE on the screen something I've never heard of or seen here in england we use 4g volte.so I'm confused also the software for uk phones are BTU/BTU/BTU OR XEU/XEU/XEU
And last the box is weird as it says unlocked by Samsung and has a warming saying reproductive harm I was thinking wtf is this phone.
Also it says Qualcomm on the top on a sticker,we use xenox version england
Ps I brought it from Amazon uk
none of it of sounds like a uk version. more like a us one.

Samsung CSC Codes List (All) | Change CSC on Samsung Devices
Today, we'll explain Samsung CSC codes. Besides, we also have a list of CSC codes or region codes with a method to change CSC on Samsung.
www.droidviews.com
Is it new?
Yes from amazon uk
So this phone cant be used here in England then other than making phone calls ?and how do I get uk firmware onto the phone?I'm a noob and not good with computers
Also changing the csc codes to uk what will that change?as we dont even have the snapdragon model in england?so would there even be uk firmware for an American phone?
Google tells me spr means sprint and that's the first code of the 3
Vzw looking on google means Verizon and that's the 3rd code so the phone was originally a Verizon locked phone.thats was unlocked and flashed with sprint fw, because the second csc code says xaa and apparently that means unlocked.
So what does this mean for me a uk user.luke I said in the uk our phones are BTU/BTU/BTU or XEU/XEU/XEU if there uk and unlocked
If you have a active sim, try inserting it.
It should come online.
My unlocked 10+ I just got did, zero issues.
If not I would return it.

How can I flash uk xenox firmware onto an American snapdragon phone?.I'm a beginner when it comes to this.as I only buy uk phones as I'm in the uk and it seems complicated flashing stuff this handset is a u version and I want to make it the f version
You cannot flash UK firmware on your US phone.
Just return it to Amazon, claim full refund as the product is not as advertised: no UK unlocked version, not new. Also screenshot in post #8 refers to firmware of a Note 9, not a Note 10 (N960 is Note 9), this makes this phone even more suspicious...
Return it. There's a lot of bs going on with sellers of this phone. This has gotten really bad. Amazon, saw some deceptive advertising there recently for this model and the N20U.
Best to contact the seller on the phone first; no phone contact, don't use. Make sure you are given full specs on their site and it's compatible with your country/provider.
Buy only a new one if possible. Used ones may be running on Android 11, you don't want that!
I was able to find a reliable US vender and got a new umlocked 10+ 256gb/12gb Snapdragon about a week ago for $800. It was as advertised except due to its manufacturing date is running on Q not Pie. It's a keeper.

Oh sorry it's a note 9 i apologise.so if I cant change it to a uk firmware is the phone useless to use in the uk other than to call people?because my sim card works to make calls
Also OMADM activation not completed message is pissing me off
What does it even mean.i think my phone has sprint firmware on it?how can I change it to normal unlocked firmware so it's nothing to do with sprint I cant stant that OMADM ITS MAKING ME MAD
And Verizon is what I think the phone was originally.
Last thing the phone was sold as brand new sealed but it's not even in the correct box the phone I have is 128gb not 512gb
And it had a sealed sticker saying euro sim only but the phone is American? I think the box is fake ?as it looks nothing like any note 9 box I've ever seen
I'm going to try and flash the phone the phone is currently csc SPR/XAA/VZW boot loader 5 I've just downloaded android 10 also on bootloader 5 ovbisly the XAA VERSION will it work or can I only download and flash SPR FIRMWARE?
as I'm trying to get rid of the MADMEN activation not completed message
Update I tried to flash it but when I pressed start in Odin nothing happened so I guess I'm stuck on spr for life unless I forrgire out how to change the first csc

Cheers the phone is u1 allready just cant change SPR TO XAA
So it's impossible to flash to unlocked unbranded so it's going back to the scammer that sold it to me on amazon

It's not impossible but if you are not experienced with better get it back, it doesn't worth the try, you can end by messing up completely.
I've flashed phones many many times before normally when I update the fw via ota and then regret it and need to downgrade back .this phone I just flashed but the start button wouldn't work because I was trying to flash XAA VERSION and not the SPR VERSION .I guess if I was to follow a guide on changing the csc from SPR TO XAA then flashing will work but what the point i wanted a uk brand new factory sealed sim free handset like I paid for
So this pos phone can go back to the scammer on amazon.its a discrace they are making fake seals on the boxes.using fake accessories and lieing saying the phones are uk.the average person would fall for this lies because the phone is unlocked my uk sim will work but you get that OMADM pop up and it's a nightmare.plus I doubt half the functionality will even work.

Baseband with the Metro ROM is G920T1UVU1AOCH, but the problem is, I flashed both of the S6's I have here to the Metro ROM to unlock them so I have no idea what the original baseband was lol I hope you do!
Any luck on the S6 Edge unlock? I scour the internet everyday for developments but I havent seen anything I feel like this S6 Edge I have is either going to sit here forever or Ill have to sell it as a blacklisted phone because its financed and I KNOW its going to get blocked.

the fact that baseband has a G920T1 means that it did changed the radio , while every damn firmware i tried never change the baseband ., is good to know though ... and if you have an S6 Edge try this before selling it .. ask to borrow someone's tmobile sim card and try to at least do a temporary unlock if that doesn't work then download the app VyprVPN select germany (i did) with the tmobile sim still in and try temporary unlock again,,, doing this at least it bought a month's use of my phone , maybe a solution will come up later on.

So youre saying that when you flash the Metro ROM to it, its not changing your baseband? I used the one posted by UnlockBase. Were you able to successfully unlock yours?
And yeah, Ive tried the TEMP and PERM unlock on the S6 Edge. I put my TMobile dealer SIM in it hoping that would help as its a free $80 monthly demo line I get for selling TMobile service. I would gladly try that method, but since we sell these phones, a TEMP unlock wont help me I need a permanent solution so once I sell it, Ill know the customer wont have any issues down the road. I have both of the S6's up for sale now that they are unlocked, but I have always wondered if Samsung REGION LOCKS these phones. Ive tested my personal ATT line in it, and it works great, but alot of my customers on eBay export these phones overseas, so Im hoping these new Samsungs arent region locked :/

when you try to flash any firmware with odin it ends on FAIL.. you can flash rom with twrp but baseband remains the same ,, so i dont know if the unlock app from tmobile is tied in the bootloader or radio or something else ... so far i'll just enjoy the 30days left and see what happens after that ... cause after it accepted my att sim card a message will appear reminding me the unlock was to end on Jul01 and if i wanna to do permanent unlock, so i flash a firmware from a canada version G925W so the reminder went away but i dont know if that means that in 30 days i'll be locked again

I gotcha. I did something similar. I flashed the international ROM on the S6 EDGE via TWRP and it told me the code is incorrect. I know the code is correct because if I ever it in with no SIM and the #7465625*638*# and put the code in it says successfull. This is SOOOOOO frustrating. The lock has to do with the radio or the bootloader/baseband.

I currently have metro pcs and I bout an unlocked Samsung galaxy s6. My original Sim is too big so I have to go to metro to get a new one but the phone is not reading the new sim in order for them to program it. How do I fix this or get around this? Should I not let metro try to activate the phone?
I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?
No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model
I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?
I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

That'll be why I still thought that then, coming straight from the S7 > S9

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint
As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?
HAPPY FLASHING!

Hi, I got one unlocked G960U1(G960U1UES3ARI1) and downloaded new fireware(G960U1UES3ARI1-SPR) from sammobile, but after flashed SPR ROM successfully, the info on the phone still shows XAA, anything I missed here? Thanks!

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.
hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

Hello all,
I have an LG G8 on November firmware (I think) on Pie, not Android 10. I am looking to update to an exploitable firmware, but don't want to pay for AT&T service.
How do I go about doing this? I can see I can buy AT&T sim cards on eBay, but not sure what to go with.
My phone is also locked AT&T, but it looks like we don't have an unlocking solution yet. I know putting red pocket on the phone doesn't give me updates and still makes it so AT&T's unlock portal doesn't see my phone IMEI.

Unfortunately, there isn't really a way to do anything right now since the pie firmware isn't exploitable. The only thing you can do is try to call at&t tech support and have them add your imei to the update database

It looks like LG installs updates incrementally, so by purchasing an AT&T sim I think I can get to the exploitable firmware just by doing a couple updates. I'll post back once I get the sim
Hey guys I havnt been on here in a long time had to make a new name, couldnt remember my old name. Anyway I have been researching non stop and I am still confuesed on what firmware file I need to download....
So here is my problem. I just bought a very nice s9 off my boss. he has had it on verizon for years. he upgraded to the s22 so i bought his old phone for $100. We called verizon and had the sim card unlocked. I restarted the phone and installed the sim card out of my Blu View 3 running on Straight Talk...Phone said new Sim need to restart the phone, so I did. Once it was back on everything appeared to be fine such as the phone having my phone number in the about phone section and I was able to make calls. The problem is that my data will not work...No internet. So I began researching and found out that I need to flash the firmware from G960U to G960U1...This is where I get confused...I was unsure If I am supposed to flash a Verizon version of the firmware since the phone is verizon, Or am i supposed to flash a tracphone varriet? I researched more and I think I am supposed to flash the XAA CSC one so that it wont have any carrier info on it and i think then insert my straight talk sim and it should be good??? idk. So I was searching for the XAA firmware download which i think is supposed to look something like G960U1UEU......But I cannot find the one with the correct bootloader version I think it is? In my S9 for build number it says G960USQU9FVB2. So am I right in thinking that i need the firmware to have a 9 in it? Can someone please guide me in the right direction please...I feel lost...
47 views and 0 replies...You guys made me feel right at home here. lmao, thank you those of you that helped. I decided ****IT and went YOLO. ODIN = PASS. I flashed the USA Unbranded XAA SMG906U1UEU9FVA1. Everything is running fine and works perfect. Thanks again FAM lol
Hello all. I had the WI-FI toggle issue where the Wi-fi simply would not turn on. All measures were taken and finally a local Samsung authorized repair agent had to replace the motherboard which did fix that issue. But I have the model listed in the thread title but the repair shop flashed the 990U firmware on the phone upon return home. I should have realized a red flag when the repairman asked me which carrier I had because they were having an issue with the firmware taking hold. When I got it home it had firmware from November 2021 and it would not update any further.
Well I took it back and then they actually got the 990U1 part right but this time it had the wrong CSC version on it (Tracfone) XAG when I mentioned that mine was carrier unlocked upon purchase so I would want XAA. The agent said Samsung only provided them with the one they put on it???
Now there are differences between the CSC versions. When the software is released being one I have read. My current carrier is LycaMobile so would not a firmware version of XAA be ideal as that is what was provided when I originally purchased the phone and what I had requested or possibly Tmobile as that is whose towers my current carrier will use. Doesn't it also matter as possible future ESIM support and band support could be different depending on the firmware correct??

To change csc samfw is a free tool which allow you to change it for free
I recommend to remove sim card first .
I think s21 should support esim . I have s21 fe G990U2 and it's was locked on t-mobile . I took it to the repair shop they unlock it and after the repair I flash G990U3 on it and now my phone has 2 imei and I can use 2 physical Sims on it .

I think s21 should support esim . I have s21 fe G990U2 and it's was locked on t-mobile . I took it to the repair shop they unlock it and after the repair I flash G990U3 on it and now my phone has 2 imei and I can use 2 physical Sims on it .

I also have the S21 FE G990U2 (MetroPCS variant). Did the OEM unlock option appear in developer options after you flashed it? I would want to un-brand my FE after I unlock it to (CSC XAA?). I would be using Mint as my carrier (T-Mobile).
No there is no oem unlock option in the developer options. It dose not support esim too . Both physical Sims are working .
