[Q] Firmware change unsuccessful

I bought my S6 in Colombia although I live in Panama. It is the SM-G920I.
I found that a Panama app I wanted to install would not install because it said the country was wrong. I guess that may be something to do with the CSC. I had naively assumed the phones in Colombia would be the same as the phones available in Panama. I now see from Sammobile that there are different firmwares for Colombia and Panama. So I downloaded the Panama firmware and installed it with Odin. Odin did its stuff and said that the installation was successful. Both firmwares are 5.0.2.
However, when the phone rebooted it was exactly the same as before and PhoneInfo still shows it as having the Colombian firmware. The only change was that I lost my Pingpong root.
Sorry for the long explanation but what have I done wrong? How can I get the Panama firmware on the phone?
TIA

You Need to download another firmware, i recommend to you to download the Trinidad And Tobago firmware, i tell you because latin america has csc codes for many countries but if your country does not have csc code it sets to latin american firmware because of your EFS Folder, if it doesnt work to you please download a firmware from France or Spain. if you doesnt want to lose pingpong root do not upgrade to a kernel made after 15 May 2015
Please do not upgrate to 5.1.1 Firmware it Sucks

Thanks. I will give that a try. Would it be the CSC that is stopping the app I want from installing, saying it is the wrong country?
If so, is there an easier why just to change the CSC? I have done some searching but everything I've found seems to be quite old and probably not working for Lollipop.

Try this to change your csc code:
1. type in the dialer *#06#, copy ur IMEI
2. type in the dialer *#272*IMEI HERE and add a #
IT WILL WIPE YOUR DATA

Thanks but that doesn't work. I get Unknown Application. I think that doesn't work on the S6. I also tried using Phone Info to change the CSC but that also doesn't seem to be compatible with the S6 even though it shows my firmware is multi-CSC.

Sorry but what do you mean do not let to install csc files? I did stop Odin auto-rebooting and went to recovery but that didn't seem to help. How do I stop it installing the wrong CSC files?
If I was willing to lose warranty now, would installing TWRP and maybe a custom ROM make it easier to change the CSC?
Thanks.

I am stuck in BNG csc code and i cant change it because i need to Trip KNOX, but i changed my csc code From ING to BNG.
- When odin finish flashing if Auto-Reboot option is ticked, your samsung will reboot and it shows a Android robot instaling something and later says Erasing... you cant let this happen, untick auto reboot and you need to reboot your galaxy in recovery mode and it will show CSC Check Failed and you have to wipe data and shutdown your device and enter in download mode and reflash the firmware.It worked for me.
if you trip knox and you install twrp it will be easier because you can install a custom rom and change your csc code rooted.

Thanks for all the advice. I am away for a few days so cannot risk reflashing my phone until I get back home. Will try again then.

Anyway to change/pick csc

I have a VOD Uk device I flashed to BTU so it was unbranded. With the MM coming out I plugged into smartswitch to change back. All went fine however it selects SIM csc and not VOD as it is a multi csc. Now I can't use wifi calling with this csc. In tried multiple flashes and wiping cache and resets. I've even gone to the XEF rom and back and still get SIM csc when i flash it.
Is there any way of selecting the correct csc or editing the firmware without tripping Knox to just install the VOD csc.
Many thanks for your help.

I would also like to know if this can be done.:good:

I'm hoping there is a bug in smartswitch in relation to the Voda firmware as other country's like Voda Germany are restoring and getting SIM csc as well not the one specified in the restor

Smartswitch won't let me restore either, it give an error saying sm-g920f not compatible :crying:.

any of you folks got anywhere with this issue? I'm still stuck on SIM

Change Galaxy S7 CSC

Hello, i'm trying to change my DBT(germany) CSC with UK one but even if i flash with odin last uk firmware with repartition, every time phone restarted main language and CSC doesn't change. How can i align product code, CSC and firmware?
Thanks

I had the same problem. After 8 unsuccessful attempts I was able to change CSC. But I had to flash ETL ROM and after that I was able to flash BTU. DBT and VDC/VD2 are nasty multi CSC.

This means you have to root the phone right? Can it be done without rooting?

I did not root me phone. CSC can be changed, but it's challange for VDF/DBT firmwares.
As I said, after 8-9 attempt I achieve to change CSC (also had custom status v DN mode).

It is randomly. If you flash another official firmware, it will change to Official status.

Hi XDA community,
I have a stock S7 Edge, which now has the XSG CSC (UAE). I want the XFA CSC (unbranded South Africa).
Problem is XSG and XFA are part of a multi CSC (OJV). Everything I've read says this can't be done unless I root my phone which I'm unwilling to do for now.
I'm sure there's a smart someone out there that has figured out how to do this!

Any way to get VoLTE working with international phone?

Hello
I bought an s8+ from HK which is the dual SIM Snapdragon version (G9550). Using it here in Australia, everything works as expected as it supports all of our bands, however VoLTE does not work. I've read this is because the CSC does not match a local CSC.
Unfortunately there are no Snapdragon versions sold here, hence no firmware with the Aus CSC (XSA) that will support VoLTE (as I read you can't flash the Exynos ROM onto the Snapdragon).
Is there any way I can enable VoLTE? Can I somehow change the CSC without an official ROM? Like go into the G9550 ROM and replace the CSC with the Aus CSC?
The only other region with the Snapdragon is the US from what I can tell, which probably wouldn't enable VoLTE either.
Any advice is appreciated
Thanks.

You may root and then flash your csc zip (or simply replace the CSC files in the custom rom with your CSC files). You should get VoLTE. Download Multi CSC file from here and extract your csc.
I do the same but with India CSC on USA snapdragon models.

Thanks nimms. This is pretty much exactly what I was after, except I cannot root the phone (work required Knox so I can't trip it ). I was hoping I could do somthing like the above, only via Odin, but it sounds like you can't change the CSC without rooting the phone due to making system changes.

Try this code in dialer *#272*imei# and change your csc from there

Hi
As far as I'm concerned, this is not possible without tripping the Knox counter. And if you try flashing the XSA CSC (via Odin), you will definitely soft brick your phone

ims setting. maybe can fix your issue ,just download a hidden app display. then you can open ins setting

Odin won't even flash it, It's pretty hard to soft brick this phone with official tools and firmware.

Interesting.
Another question...the only difference I've noticed between the 9550 (HK) and 955U (US) is that the US version does not have Band 28 but the HK version does, which we do use here in Aus.
If I flashed a US firmware (which has the same S835 SoC), would I lose Band28, or would the modem still be able to use it?
EDIT: what if I only flashed the CP file (modem), is this interchangeable between the different SoCs? Could I flash the XSA CP (modem) onto another ROM, or will this soft-brick?

My IMS is saying "Not registered" in the about phone. I can't seem to do anything about it, and the hidden menu doesn't give me the option to change it.

IMS setting is located explicitly on "Settings -> Mobile Networks -> Access Point Names"
The best bet you may try is to find a Samsung phone thats currently in VoLTE then copy IMS apn settings onto you phone (you manually input the settings).

Do not enter people astray, ADB Sideload It's not working - error "signature verification failed"
need ROOT
VD2-CSC-S8S8p
MY Galaxy S8+ SM-G9550, SW - G9550ZHU2AQL2

Just download an official ROM (A variant from a country that supports VoLTE) for ur model from sammobile or u might even find it on the xda forum and flash it via odin with Home CSC.
It works well... No need to root n KNOX counter wont be tripped...
PS: Backup data.. They will be lost in the process.

Now we're talking about ADB, not ODIN or TWRP.
Flash via ADB Sideload - not possible. You understand me. Smartphones snapdragon not flash Exynos SW. You can only edit an existing profile CSC or add new CSC.
Example:
my smartphone TGY (snapdragon model SW)
but I live in the region of SER (EXYNOS MODEL SW)

But as far as i know, Exynos CSCs also dont go with the Snapdragon CSCs... I could be wrong.

Is it the mismatch between CSC codes?
Firmware and active CSC codes are different.

Well, you have a phone from Malaysia; while the ROM is French.
You can change both.
To change ROM CSC that's simple. Grab the relevant CSC rom from Sammobile or any other firmware site and install via ODIN. (Most phones have a relevant section/guide in their XDA sub-forum.)
To change device CSC, you need tools and it may not be supported at all. I used "SamKey", you need to buy keys from the company, but it worked. On my Note 10+ it worked, on my Note 9 it worked, on my S10e it worked. On my Note 9 512GB it failed. Basically the tool has to support your specific device variant AND if you are on latest firmware you must wait because they need time to make the tool compatible.

With one CSC firmware i should flash?any suggestion??

Well, I suppose you want to match the device's CSC, so I'd grab the XME one from Sammobile. And you need ODIN to flash. The whole ordeal should not affect your e-fuse/warranty/KNOX status. At least I never managed to trip mine by doing these.
But, I also used mismatch CSC firmware for months if not years at times and it didn't do a thing. Like I didn't notice any difference. I wanted to enable call recording, but I realized it only works if I change device CSC and then also flash the relevant ROM.

SamKey is a paid, third-party software.
- You have to buy credits for it to work. So you need to pay.
- It may or may NOT support your device (they do refund if it's not supported).
- You don't need to be a Hollywood hacker to use it, but if you are really unfamiliar with everything in general - I would recommend not using it.
