Carrier not found

Hello,
im new here . so please mind my mediocre knowledge.
i got a rooted phone Galaxy A5 520F in Germany, then i wanted to go back to the stock firmware and unroot this phone, while im in Germany i chose Germany DBT for all mobile carriers.
everything went okay till i inserted the sim card then the phone gets in infinite loop.
i tried another German carrier firmware but i faced the same.
so please can anyone help me with this issue?
best regards

S9 Message Your current software version isn't supported. Visit a service centre

Hi first post, please be gentle
I've got an s9 which is on EE UK, I flashed the phone with stock firmware, I did run into a couple of issues where when flashing the phone it got stuck on odm.img so I had to start again but using CSC and not home CSC so I lost everything
When the phone rebooted, it started up in German, so as I had my sim card in, it restarted in English
I'm using the following
G960FXXU2CSA2/G960FOXM2CSA2/G960FXXS2BRK3
Service provider SW SAOMC_SM-G960F_OXM_DBT_PP_0009
DBT/XEU/EVR
When I check for updates I get the following
Your current software version isn't supported. Visit a service centre
Can anyone help on how to put this right, I want to stay on stock firmware, not EE firmware
Thanks in advance

Good morning, I have a problem with my S9 model G9600 which came from the factory with the firmware of Hong Kong, however I tried to change the firmware for the one in Colombia because some voice services of the operators only work with the software of the country. But when trying to flash the part of CSC I mark the error and obviously the installation fails as in a kind of A brick because the logo of Galaxy S9 does not pass and is only solved by reinstalling the firmware with which it came from the factory; I have already made sure that the binary is the same, however I can not find a solution. I attach photos of the error.

You need to flash the XEU firmware, you have the German DBT firmware running right now

are you having an identical issue? i ask that because resolutions are very specific. Flashing firmware from www.sammobile.com/firmwares is very commonly the fix for a great many issues, but id hate to have you go thru the trouble of doing so if its not necessary

I tried flashing using odin but didnt work. btw, im using SM-965U and currently residing in Thailand. I dont know if this is the reason why I cant update at all.

S9 message
I am in the U.S. and am getting the message that software isn't supported also. Is there any resolution to this problem?

In case it helps, I was having this same issue with my unlocked Galaxy Note 10+. I found this thread after searching. I had gotten into this situation by flashing CP/AP/BL from TMO firmware without also flashing TMO's CSC or USERDATA. I avoided CSC/USERDATA (I was using the home CSC) because I wanted to avoid wiping the phone.
When I finally gave up and flashed CSC and USERDATA, everything was back to normal.

have you tried flashing the stock firmware via Odin?

O2 branded SM-G960F to vodafone

I've got an O2 Galaxy S9 and I'd like to use it with a Vodafone SIM in UK.
Is it just the firmware that would need changing or would the ROM need to be changed too?

the firmware contains the ROM, but the ROM wouldnt have been what prevented you from using this to its full potential. Technically, all youd really need to do is flash your carriers CSC and even maybe the HOME_CSC. If youre unfamiliar with those terms and/or processes, just flash the Vodafone firmware with the CSC (which will factory reset it) and call it a day

Hi Youdoofus,
Thanks for your help.
Can I just run this past you then.
The phone came brand new from O2 and is not locked to the network.
I'm using a Vodafone SIM in the phone and I have trouble receiving SMS, making 4G calls, etc.
I understand what it is to flash the phone with new firmware although I've never done it before.
If I flash the phone with the latest Vodafone firmware and Vodafone or generic CSC that should be enough to get the phone working ok with the Vodafone SIM?
Sorry if the question seems basic. This is obviously not my area of expertise.

no worries mate. nobody is innately knowledgeable about this stuff, even the seasoned linux vets can stumble about a bit.
but yes, all you really need to do is flash the Vodafone or generic/multi csc and youll probably be good to go. the reason your sms isnt working is likely due to your APN settings and voLTE wont work without your carriers own CSC installed tho. That being said, many of the multi CSC firmware packs will do the job quite nicely as they will likely have Vodafones CSC in their list of available CSCs. It would be different if you used a fly by night carrier

I flashed mine with unbranded generic UK firmware BTU-G960FXXU7CSK1-20191121174240.zip.
Got it here, took forever: https://samfrew.com/download/Galaxy__S9__/5vgs/BTU/G960FXXU7CSK1/G960FOXM7CSJ5/
Probably better using Frija to download it quick but I couldn't get it working:

Final Samsung Android 10 should be out any day now (if you can wait).
Big fan of this Lineage 17 10 rom by Abtekk if you fancy something custom:

Currently running that with White Wolf kernel & Zoran's GCam, good luck!

A little help with flash firmware

Hello guys. I am from Europe and just buy Samsung Galaxy S20 Ultra with Snapdragon. The phone is unlocked, but have carrier brand, Verizon, I want to remove it. Can't change phone language (see that this problem is discussed here, but I did not see a solution) and in Verizon miss Samsung Cloud.
I decided to try changing stock rom with Odin. Now downloading official firmware SM 988U, because I read that must put firmware with "U", and downloading SM-988USQU1CTLB (this is my baseband version and hope that this is correct firmware), write only USA, without any brands, from sammobile, I hope that is without carrier brand. Don't know if I will manage to change language successfully, because the phone is made for USA, but hope that carrier brand will disappear and Samsung Cloud will show. Will do this for first time and don't understand a lot of things. However, my question is for Bootloader.... I try to see if my bootloader is unlocked or locked, but can't do it.... If I put new firmware and bootloader is locked what will happens? Sorry for my stupid question, but I try to learn how things happen What you think, is my idea is good or no?

Something is bricks. I downloaded the original stock firmware from sammobile. USA only, I successfully uploaded it, everything with Odin was good, but after restarting and entering my sim card pin code, the phone want pin code to get app notifications. Please someone help me.... What is this pin code? I can only received phone calls

I manage to put the phone in downloading mod, please someone tell me witch firmware must download and install? The phone is SM-988U

Question about flashing a stock KDZ rom from a different region

Hi all, I currently have a G7+ with the model number LM-G710EAW. From this site, there's a few EAW's that get the android 10 update, that is the HK, KR, and SEA. To this day, my phone is still on Android 8. Since that the only way to check the phone region via IMEI is now gone, I have to assume that my phone's region is IDN (I bought it in one of Indonesia's domestic store). With that, I have a few questions
1. Is it safe to flash a SEA KDZ to a IDN phone? Is there any possibility of bricking it?
2. What about the baseband compatibility? Can I still use the cellular network?
3. Is there another way to check an LG phone's region?
Thanks in advance!
