ive seen other threads on this topic but none really answered properly.
I live in Ireland and bought my phone unlocked from the UK , i want to get my stock firmware back but i cant find one that suits my model and version. So would i
harm my device if i used a firmware from a different country that has the correct firmware i want????
s4 i9505
If the phone is unlocked you shouldn't have any issues. Except with CSC maybe.
whats CSC exactly?
Consumer Service Code, which is what Samsung uses to customize the firmware for a particular region. With devices that are locked to their carriers this also means the apps that the carrier wishes to add to the firmware. In your case, since your S4 is not locked to a carrier you can install any stock ROM you wish from any region. For example, my unlocked I9505 was originally on O2 in the UK (CSC O2U). When I purchased it from its original owner it came to me with Slovenian firmware (SI Mobil, CSC SIM). I subsequently flashed unbranded firmware onto the device and ended up with a device that thought it was Swiss (CSC AUT). In this last instance, three Swiss-specific apps were added that are not found in the other versions of the firmware. These apps were added because the CSC reported itself to the firmware installer and said, "install these apps as well". Had I changed the CSC to BTU I likely would have gotten some UK-specific firmware.

hi guys. anyone experienced the same. here's what happened:
i was using i9505 glb kitkat (csc=glb=globe philippines). i flashed clockworkmod, then install carbon rom.
last month, i re-flash my original glb kitkat. then went to recovery. i noticed that the csc changed to sin (singapore singtel) without doing anything.
now my problem is what rom should i use next time i update to lollipop: glb or sin.
pls help and many thanks.
Is your phone SIM unlocked? If it is, it doesn't matter which CSC you use. Otherwise, stay with CSC GLB.
No. I used regionlockaway to make it sim unlocked.
Then as mentioned, the CSC doesn't matter. Case in point is my I9505. Originally an O2 phone, when I purchased it the S4 was already unlocked and had Ukranian firmware on it. When I installed the Black Edition UK firmware (CSC BTU) after repairing my S4's SIM tray and again removing the SIM lock, I ended up with CSC AUT (Switzerland) instead.
On an open firmware such as CSC BTU, there are actually multiple CSCs within the firmware, and all the CSC does is customize the firmware to the needs of a specific region. In the case of AUT, the firmware installed three Swiss-specific apps that could be easily removed. BTU and the other CSCs essentially do the same thing, and I am guessing this is without modifying the firmware itself.
Ok. Thanks guys. I'll still use glb firmware once lollipop is released. I had once semi-bricked my s4 (got repaired at samsung center) so i'm kinda nervous this time.
Is there any problem installing a stock firmware from a different country (let's say UK, downloaded from sammobile) to my Italian phone?
thanks
No. Unless it is carrier locked, then it might be a problem.
Hi i have a 9500 S4 Exynos version, the international version, i recently upgraded to Lineageos but i want to go back to stock but i don't know which Rom to choose because of the region code. i live in dominican republic and i don't want to install the one for my country because it will probably be filled with bloatware from Claro (local carrier) and i don't know if it will probably lock the phone, the phone is factory unlocked by the way. Can someone can pass a link for a Stock rom running lollipop with the international csc?
Download CSC CAU from sammobile.com, but I cannot provide a link due to site rules. CAU is for countries in the Caucasus mountain range in Europe, and is probably your best bet to be bloat free. You may still wish to download the Dominican Republic firmware anyway, in case of issues with the CAU firmware.
I'll try that
Hello,
Can someone please try to explain this to me:
When I flash a multi CSC firmware on my S8, from the same region as my original firmware, how will the phone decide with CSC to assign from the multi-CSC list?
Example:
I have an S8 from Vodafone Romania and I want to flash the Romanian ROM firmware. But this firmware also contains other European unbranded CSC codes.
On what basis will the phone assign ROM as CSC to my phone? Based on the SIM card?
Many thanks.
No matter.
I have reflashed my branded Vodafone S8 with the open firmware for Romania. After, did a wipe cache and factory. Then the phone asked me to accept another reset to apply features from my sim card. Done that and the CSC is now the one from my country ROM. So, short answer, keep the sim card you want the CSC for in the phone to have specific settings
Samsung Galaxy S7 Edge: SM-G935F
Hello everyone,
So the reason I'm asking for guidance and not straight up trying what I found is because this is my only phone and I cannot risk or afford fixing it if things hit the fan like i'd do with a spare or an old phone.
In addition the region code attached to it, the code is carried by different carriers and countries in the Gulf Area, some of which received Android 8 and some haven't. However since my phone wasn't purchased from STA, saudi telecom, I don't believe it received the updates distributed to the country,. So currently my phone was bought from a distributor in Saudi Arabia, which usually carries codes from different gulf countries. That region apparently hasn't received updates since earlier this year.
I'd appreciate just simple guidance for this process to get it right.
However I do LIVE in the UK and I would like to flash my phone to a UK region, I'm unsure which code to use and what files I would need to place in Odin.
Phone info:
Samsung Galaxy S7 Edge: SM-G935F, Unlocked (They usually require you to use a local sim card for a 5 minute call after which it's fully unlocked)
CSC: G935F0JV1DQIL
AP: G935FXXU1DQJ8
CP:G935FXXU1DQIL
Would it be possible to flash to UK BTU as they receive more frequent updates?
I don't know if this has any bearing but I'm using a Three sim card at the moment.. However I have used around 8 different sim cards/companies in this phone since i purchased it.
I would appreciate any advice on what files to place into Odin if I want to keep my data. (Or if I have to completely wipe it?) or shall I switch to another up-to-date OJV country like Emirates (UAE)?
Also i'm not sure what home_csc file is.
hope to hear from you guys soon.

good day
I purchased my device SM G935FD from Oman with CSC XSG (part of multiple CSC OJV middle east and some African countries). Even though I received OTA, I always install the full firmware upon officially released.
I upgraded my device from Android 7.0 to 8.0 using UK BTU firmware, the availability of which came first.
In short I downloaded the firmware from Updato (Sam Mobile slow and lagging) for the BTU firmware. Just to be sure you have to download the correct and appropriate firmware and also the latest Odin (Odin3v3.13.1) which was upgraded by Samsung to be utilized for Android 8.0 and higher versions.

Also, be sure to activate your Developers options and enable USB debugging and unlock OEM. Using Home_CSC will retain your user data while using CSC only will factory reset your device and start anew.

About Knox tripping?
Hello, I'm expecting to do something like this to my phone, but I'm wondering, will it trip Knox? Because you're changing the ROM, so I don't know
