S21 CSC change to Poland XEO? - Samsung Galaxy S21 Questions

So i have S21 on Croatian T-mobile, CRO CSC, but they are slacking to release two latest updates already.. Other providers already released updates... so i decided to change firmware and flashed Poland XEO firmware with Odin. (also in anticipation of OneUI 4 Beta sign-up).
All went fine however i'm now on latest firmware and security patch, but CSC still showing CRO, it's really confusing since my provider doesn't even have this firmware released yet. How will this affect my future updates? So weird that samsung is now not allowing CSC change.

I think there are a lot of problems to change CSC after September security patch. I'm having trouble with a s20+ september patch, tried many methods to change csc but nothing is working so far.

Yeah, it's not possible anymore, i even tried with SamKey yesterday but it doesn't work. Even downgrading to July firmware it won't work.

I don't think it's the end, something should work soon. Let's stay tuned and cross fingers.

Different country firmwares have different app versions...

Hello,
A friend and I have the Galaxy A3 2017 and both are on the unmodified stock firmware. He is on the German DBT firmware and I on the French FTM (Orange) firmware. We both received the latest January
2018 update via OTA. But on the DBT samsung camera is version 7.1.34 and has a new feature like putting stickers (hats, cat faces....) when taking selfies. The FTM firmware has samsung camera 7.1.23 and does not have these effects. Contacts and calender app are also a newer version on DBT than FTM. Who decided to not update these apps on FTM? Samsung or Orange? And why?
Looks like I found something nobody ever heard of

Just checked my camera app version, it's 7.1.42 and if i remember correctly it has had the stickers since marshmallow. I'm still on November security patch.

no security updates since march 1, 2020?

Hi all,
so I bought a V60 with DS yesterday, it was an open box but all the plastic still on device, like brand new and was able to test it and reset it to factory default before buying.
everything fine with setting it up but the phone doesn't update the security patch level..it says: you are using the latest software version for current OS.
patch level is from march 1 , 2020.
anybody knows what could be the issue.?? i've haven't found anything on this issue on the internet yet..
info:
model LM-V600EA (i think this is the Global unlocked version.?) my country is the netherlands and have a Vodafone SIM, i am able to make phonecalls and use data 4G+
software version v10f-EEA-XX
android version 10
buildnumber: QKQ1.191222.002
KERNEL 4.19.81
ive tried to use the LG Bridge software but when it want to update the driver it cannot make connection to the server.
when i want to install the driver by myself, it says that the os version (using a mac os catalina 10.15.6) is not supported...sigh..
looks like the unlocked version doesn't update.? the US verizon version have had several updates, even the latest august sec. patch level.
if someone could shed a light on this, or knows what is the issue...already very thankful.

--UPDATE--
hi all,
i succeeded with updating the phone.
I used a windows 10 laptop, installed LG drivers and LG Bridge software.
it found an update, downloaded it and installed it. whole process took about an hour. download was very slow.
now i have the July 1 security Patch update. (not the latest which is august, but ok, it's LG)
software version is now v10m-EEA-XX.
camera software also updated.
still wonder why the phone is not updating OTA.
BR
Mike
I have the American AT&T model and received the August 2020 patch as an OTA a few weeks ago.
Since receiving the phone around April 1st, I feel like we've gotten every other security update.
IIRC, something like March (came with it), April, June, and August. But my recollection is a bit hazy.
On t-mobile tje July security patch is the most recent release. We've also been getting every other month or so, so I am expecting an update sometime in September hopefully
still don't know why the OTA update was not working. maybe because I have an unlocked version of the V60.??
as (security) Updates are being pushed out by carriers, i had to update it via LG Bridge.
bi-monthly update check via PC it is then.
thanks ya'll!
I also have unlocked eu version same as yours and all updates on mine was done OTA, I'm on July at the moment.

do you also have the -XX in your software version.? I've read somewhere that XX on software LG phones indicates it's a test/demo model..maybe that explains why it was a open box when I bought it..
anyway..I was able to flash it with firmware V600EA10M_00, (NLD Region) ive used LGUP, hoped that the XX in the software version was removed but it isn't.
Also found a V600EA10K_00 version..Think Im gonna isntall this one and see if there's any difference, want to know what the K and M means in the firmware.
if anybody know what it means, let me know!
Thanks all!
Mine is LM-V600EA, V10m-EEA-XX.
I bought mine from Belsimple from Netherlands and actually use phone in United Kingdom on EE network. Definitely not test version. Letters in software version indicate release as lower letter then never software, same with other LG mobiles ( I had G3, G5, V30).

thanks for the info. so if i flash it with the K version, it would be an earlier version of the software and security patch level. then I leave it with this M version.
do you have an idea on why the OTA was not working for me then.?
as we both have an unlocked version and mine wouldn't update OTA. phone was on security patch level of 1 March "out of (open) the box" and on software version v10f-EEA-XX but OTA said I was on the latest version of OS.
When I opened nine from box first what I done I checked for updates and it's downloaded straightaway. Did you connected through WiFi or mobile network. Maybe updates are set to not download through mobile network etc. Also the way how software number show up it's mean that is unbranded fw, if you will have branding fw it will show something like v10f-234-30 (for UK EE network), mine unbranded eu open V30 also show similar to V60 where on v30 is v31a-EUR-XX (latest stock Pie)

First thing I do with new mobile, updates: also connected it with Wifi and Mobile network, went back couple times to factory settings, no result for OTA.
I was able to update it via LG Bridge ..really strange that mine was/is not updating OTA.
when new patch is available for v60 I will check if it's doing OTA
thanks fo input!

--UPDATE--
recieved an OTA update, security patch september 1st.
installed it and now om on Software version V10n-EEA-XX.
thanks again!
Thanks for update, on mine still say v10m is latest. Didn't plugged to pc just checked on mobile.
Hello, my LG V60 LM-V600EA still has not received the security patch from September 1. I am in France where it isn't sold, I bought it on eBay (open box, new phone according to the German seller, the second screen was sealed), and English UK language, at startup (nothing abnormal).
Nothing by OTA, LG Mobile Support Tool and LG Bridge does not recognize my firmware: V10m-EUR-XX. No problem whith IMEI and serial number. I received it 10/02 but the downloaded update was July 1st.
I found this strange link on the internet: lg-roms.com(???) (I don't even know if I can trust)
The latest versions are Polish (POC) and Italian (VID) . In m we find the NLD version.
Question: if one of these rom works is it reasonable to flash by LGUP or I wait for LG to update the EUR version?
Thanks
hi, I sold mine so I cannot test or tell you on which security patch LG has pushed now to the v60. the Rom site you can trust, i've downloaded and installed the V600EA10M_00 ROM and installed it via LGUP tool. but it didn't made any difference. the software version, security patch date and build number stayed the same. Also didn't got any OTA updates..regarding the official firmware..the OTA suddenly was there when I had it in September. The LG bridge tool helped me to update it to the July sec. patch but LG Bridge tool was a bit of a ''''''[email protected]#$% to get it working correct (drivers, latetst version of the software, wasn't able to connect tpo the server error's etc) eventually it worked, but still after this no OTA....I would wait for LG to push the updates..maybe it's a comfort to know that LG is really 'lousy' with updates...couple of month's behind with Security patches is 'normal' You have to play the waiting game...Hope this helped, Best regards

Thanks for your help.
I took the risk of flashing the ROM in version n version VDI (since it works) because selling it now will not bring me much. Unfortunately (but logical) I remain in the EUR-XX version so goodbye to updates.
If the site remains update, I will always have the option of going through LGUP. Anyway VDI, POC, NLD, they are the same versions as the EUR that LG forgot (my LG V0 is however in global version EUR-XX).
Thanks again
If you read my previous post you will know by now that is nothing wrong with EUR-XX version. My current version is v10n-EEA-XX September security updates. All my updates done via OTA, mobile bought in Netherlands and still in use in United Kingdom.

The problem with EUR-XX, no update since 07/01. Nothing by OTA, LG Bridge doesn't recognize my Firmware and LGMobile Support Tool can't find a other update than m version. Nothing wrong ?
Edit: I try to install the m update and ... nothing : no upgrade to n the 11/12.2020.
You can try to remove sim card and try update without sim. I know that while ago orange UK blocked updates on some lg phones, once users insert different operator sim card mobile phone find updates immediately. I never had any issues with my v60 where this mobile is not in UK market, still working fine and update OTA.
If you still have issues try to use vpn for different country and update with lg bridge without sim card.

Unfortunately it's too late, these updates have messed up my LTE frequencies. In short, I am missing frequencies that make 4G + unstable in France. Now between 0 and 20 mb /s, before always 30/40 with EUR-XX firmware, watching YouTube has become hell without wifi,
my LG V60 is just an phone without a real LTE! (VDI, POC & NLD have this problem because I flashed in refurbish, it's my fault).
Otherwise OTA updates work fine but not beyond version m (EUR version). Now it's too late.
NB. 2 whole days trying to find a solution, I lost my time. I thought that the modem part was common between all European countries like for Samsung, with LG: NO!

Regarding not receiving OTA updates

It's my first time here, and much of this is new to me.
Anyways, I have an S21 (Snapdragon) with Multi-CSC? OYN, XAA/XAA/XAA that I use in Singapore. (SM-G991U)
I just learnt that apparently OTA updates are only given after the location of where the device is being used corresponds with the CSC.
What would my options be now, to update my phone? (Being able to have OTA updates would be preferable)
I know of (just learnt):
• Changing CSC via the phone app (using IMEI number). Never tried and I don't know if I'll get an error code. My main concern is that I'll not be able to update if I get firmware for Exynos instead (S21s in Singapore are Exynos), if I even get a Singaporean CSC on there.
• Flashing/ updating using Odin? (Heard it doesn't work anymore for changing CSC? I have One UI 3.1)
• Updating using ADB?
I'd love to learn something about this whole CSC mess too so I can understand what's happening and how everything works. And if it's not possible to get OTA updates, the best way to update my phone then. Thanks

Hi Mate
OTA are strictly Active CSC related , independent of the country you are using the phone. I have Spanish active CSC and i get the OTA in Panama
So you will get a new OTA as soon as available , the latest for you CSC (XAA) firmware is:
Date
Version
2021-06-27
11
PDA
CSC
G991U1UEU4AUF5
G991U1OYM4AUF5

https://www.sammobile.com/samsung/galaxy-s21/firmware/SM-G991U1/XAA/download/G991U1UEU4AUF5/1557396/
You can change the CSC but it will depend in what firmware you have and what CSC available that firmware has.
To your questions
1 You will not get an Exynos firmware in your phone as you can not force an exynos CSC into an Snapdragon , Singapore does not have Snapdragon firmware , so you can not force a Singapore CSC into your phone
2 Flashing new firmware does not change the CSC anymore ( in my case did not)
3 Update with ADB ? not sure what you mean but if you mean firmware , no is not possible

Thanks for the reply. Problem is, I've constantly checked for updates but I'm still stuck on the February patch which should actually have even came preinstalled on the phone. (basically, I've not received a single OTA update). This has led me to believe that the country you use your phone in affects receiving OTA updates.
I doubt there's other reasons why I wouldn't receive the updates (since other people have said that location/ connecting to the telco network? affects OTA updates).
Anyways, so to clarify, my only options to update then would be to use:
• Smart Switch (holding off because it is disabled from an app having device ownership)
• ADB (sideloading OTA update)
• Odin (unfamiliar with its uses)
I'm just looking for the path of least resistance to get my phone updated right now. And just to confirm, updating/ flashing (are they the same?) software will not wipe my phone?
Thanks.

Hi
Is hard to say what really going on , as i said I have an active CSC from one country and live in another and get the OTA with no problem ( lot of people do)
Easiest option for me would be doing updates manually with odin , download the correct firmware and flash using the home-csc file , that way the phone will not be wipe , will be like a regular OTA
Check this threads , here and here even if the thread talks about an exynos the procedure is still valid for a snapdragon
I still dont get OTAs. I flahed BTU, PHE and OXD but nothing. anyone else facing this?
I flahed with odin.

Combination firmware

Hello, I came across "combination firmware" for my S21 - will this work to downgrade my firmware version? I'm looking to change the CSC which I haven't been able to do on the latest firmware.
All those various CSC change dialer codes don't seem to work on the latest firmware.
Dialer codes stopped working since February, 2021. CSC changing became pain in the neck, if you're too afraid to lose KNOX, you'll have a rough time following this guy.
Thanks! I tried that, but it didn't work.
Hopefully the SamKEY folks will get this figured out.

Galaxy s21 not receiving updates

I have a Galaxy s21 olympic edition with number SM-G991Q and i am not receiving montly updates. The last update was the August 2021 patch and was installed on August 30th.
Also smart switch on Windows is not detecting Any new updates.
I tried to reset the device without luck getting new updates.
Does anybody has the same problems with the Galaxy s21 SM-G991Q not receiving updates?
I have this phone too, I also only got the August security update.
Don't worry, they probably lost their update schedule before switching to Android 12. I got updates yesterday for SM-G9910.
I have the same phone and find it odd that it doesn't show up on sammobile or anywhere else.
Does anyone know where to find original firmwares for it?
I have too G991Q and I need flash to XAA because I need BAND 20 LTE my country help me pls or altwrnative stock ROM?

Well on november 8th i finally got the october 2021 update. Hopefully the android 12 update will follow zoon
I have a question about the G991Q, did any of you get the ESIM to work yet? It is currently software locked - in theory it should have it because it is a Snapdragon chip
Do you have Android 12 on G991Q already? Im checking every day but still no luck Should I install non olympic rom? Will that work? Thanks
@Corbik
This particular variant has yet to receive the stable One UI 4/Android 12 update.
@jussy
See here; the model number of this variant is SM-G991Q and the CSC is SJP. At the time of posting this, the latest available firmware version is G991QOPU1AUJ2.
my version is g9910 and still no update to android 12.
last version a11 octuber security update....
whats happend....
What standard version would be closest to G991Q? I tried to flash U1 ROM but no luck
Friends i'm also with the SM-G991Q olympic version.. I really need to switch to CSC from ZTO, to try to use VOLTE and WIFI CALLING from my operator in my country, Brazil!
Can someone please help me change CSC to ZTO ? I tried the tutorial above, but it doesn't open anything when typing the codes, were you able to change? I saw that it only works on android 10. but we are on android 11.
I saw that you have the option to change CSC ANDROID 11 via Samkey, but I believe it still doesn't have support for our SM-G991Q device.

Have you tried switching to another S21 variant's ROM with Snapdragon 888? it worked out ?
If it doesn't work, I think I found our ROM to perform restoration via ODIN, in brink event:

Yes I tried the U1 version since it should be US version with Snapdragon888.
That ROM you found, based on the numbers is exactly what is in my phone now.
I think I will just wait some more time to get official Android 12 update, hopefully our special version wont be forgotten
But If somebody know which ROM would also work for SM-G991Q and ideally would also support all languages and features (esim for example) please share
