OTA Upgrade Question - Galaxy S 5 Q&A, Help & Troubleshooting

I understand that if i put a custom rom on even another stock firmware for another region other than what my phone came with i won't get OTA updates.
That i understand. I was wondering though how does it know that its not the firmware that came with the phone.
For example if i put BTU on my carrier branded S5 it won't update but how does it know thats not what it came with. What is not changing when it gets flashed.
Is it based on IMEI or is there another parameter that does not get changed when flashing another firmware.
Thanks for your help guys i like to really understand whats going on.

anyone any thoughts

I don't know how it works exactly, but here is one of possible ways:
Samsung stores the device's S/N and the initial CSC in its database.
(You can check that by using Kies 3 software > Tools > Firmware Upgrade and Initialization, enter your S/N and Kies 3 will show your initial CSC).
That way, when you perform an OTA update, Samsung will know if your current CSC is the same as your initial CSC or not.

updating to froyo which one and how

Got a galaxy S i9000 yesterday and i am looking at updating it to Froyo. When checking for update using kies it says there are no updates available. The only other option is by tricking kies into thinking there is.
pressing *#1234# shows
pda i900jpjg8
phone : i9000jxjg2
csc : i9000jpjg9
IN Settings > About Phone > Baseband Version it shows i9000jxjg2
The phone is unlocked and unbranded.
Can Someone please point in the right direction as what would be the best way to flash froyo on it? I know tricking kies is there but what should i trick it to exactly? What code to use?
/Edit : Which is the best product code to enter for kies to flash froyo? With all these choices there must be 1 ROM that is open and quite good.
Any help is appreciated.
Cheers
This is the thread for patching Kies for Froyo, there are different Roms for different regions, you need to decide which region's Rom you want.
http://forum.xda-developers.com/showthread.php?t=835628
most of the ROMS in there are for certain carriers in certain country. Isnt there a ROM that universal and can be used for any phone. If i were to say pick an european ROM which would be the best one to go for. no carrier branding nothing.
thanks for replying.
Check out this thread and instructions you will have the European upgrade with this. (post 80)

[Q] How to Get Official Updates via OTA/Kies

Hello everyone,
I got confused after reading a lot of posts and threads about the subject, because each one says something a little different.
A little background:
I bought a new Galaxy S4 GT-I9505, it comes with android 4.2.2 and I wanted to update it to the new 4.3.
But when I try to update via the software update in the phone, I get "The latest updates have already been installed", and when I try to update via Kies I get "Your device's current firmware version is not supported to update firmware via Kies".
Click to expand...

My phone version is:
PDA: I9505XXUBMG7
Phone: I9505XXUAMDC
CSC: I9505EVRBMF5
Now, after reading about it I still don't understand why I can't get official updates, but I think it's either of the following:
1. My CSC and PDA do not match.
2. I changed my CSC to something different than the original.
I don't know which one of the above is true.
Anyway, I don't understand how this can happen if I bought a NEW phone?!
If 1 is true then:
1. What does that mean? What should match?
2. How come I get a new phone with CSC and PDA that do not match?
3. How can I get them to match so I can get official updates?
If 2 is true then:
4. This is a new phone, so how come this isn't the original CSC?
5. How can I know what the original CSC is?
6. What should I do to get the correct CSC (and get official updates)?
I would very appreciate if you try to help me.
I really want to finally understand the CSC and PDA stuff and get myself to have official updates via OTA/Kies.
Thank you in advance for helping.

[Q]Why can't I update my stock software?

So last night I flashed stock firmware from sammobile,after that I flashed the appropriate modem for the wifi to work.Everything is good but I tried from curiousness the Update Software button.It says my software is modified and I can't update it.Why?!

Reflash everything with a full (not modified) stock firmware. That's because you flashed file that not corresponding the stock firmware you installed, so the OTA update will break.

I flashed a stock frimware! First I wiped everything from my phone except storage and flashed the stock firmware from sammobile.It is completely stock right now...
In order for OTA updates to function, the parts of the firmware must match each other, and the firmware must have the same CSC as originally installed on the device. For example, my S4 originally was from O2 (CSC O2U), but when I got it off Swappa it had the CSC of SIM installed. I would need to install the O2-branded firmware back on to the device in order for OTA updates to function.
If you do not know what the original CSC was, either because the phone was a "hand-me-down" or was purchased used, then OTA updates will not function and you will need to use Odin to update.

It doesn't matter. Because we look on firmware version, not release date.

So ,can I change my CSC ? Or is there any way to find out what was the original one? Any other things that need to match in order to update via OTA? Or you kinda say it's impossible to do that if I already modified the original software.Btw I have a i9505

To identify what's the latest firmware for your region, use your hometown's CSC code (region code) and look for a new version available.
Like I9500UBUHOI1 for region ARO, I9500XXUHOH7 for region SER, and many more. If you're unsure, check your CSC code by entering Recovery mode or use an app like Phone Info.
@calinoii: Many S4 boxes will have the CSC on them as part of the Samsung merchandising code, though mine did not. If the box does not have it, or you don't have the box, the only way to get the correct CSC is by parsing the IMEI and finding out which carrier purchased that device. imeidata.net used to have that option available, and it was how I found out that my device was originally from O2. They took it out, and I'm not aware of any replacements. Try contacting your carrier, as they may be able to provide that information.

so I checked on sammobile and the csc for my firmware (I9505XXUHOJ2) is I9505XXHOJ1. Maybe it has been installed with the firmware?

I guess I wasn't clear. When I say "CSC of the phone", I'm referring to the three digit carrier code some of the devices have. For example, my phone I discovered had the model number of GT-I9505ZKAO2U. The carrier code of my phone is the last three digits of the model number. It therefore is O2U, and on sammobile.com I would narrow down my search for ROMs using that code to get the correct ROM for the device.
The firmware has its own CSC code, but that cannot be used to determine the phone's CSC. You either need the model number of the phone as printed on the box, or you need to find someone who can research the IMEI and tell you what carrier the phone was originally sold to.

No, that's probably modem or baseband version. Like Strephon said before, it refers on latest 3 digits on your phone box. Like my Galaxy S4 is GT-I9500ZWAXSE, so this phone is for Indonesian markets. Third party app might refer it into installed CSC codes like I install Latin American firmware into my phone and it's changed into GT-I9500ZWATTT. It mostly refers to region like region CHN for China, ARO for Argentina, etc.
CSC that always mentioned on the firmware details is actually multi-CSC. Like on SEA I9500XXUHOH7, it's multi-CSC version is I9500OLBHOH1 and Latin American I9500UBUHOI1 is I9500UUBHOE2. Multi-CSC applies one of CSC codes that matches your phone (like I download ARO firmware but after installing and wipe cache, CSC code installed is TTT instead of ARO).

"Warning: Your phone does not have active CSC code" - Reasons?

Hi all,
Last week I bought a Samsung Galaxy S7 Edge through ebay. Everything has been great until it came time to plug in my recently purchased Gear VR which is coming up with a network error. After some searching for solutions, it appears that my phone isn't set to a specific country (so I guess it doesn't know what software to install). I have installed "Phone INFO" which shows as per the attached screenshot.
My question is what could have caused this? If I was to reinstall firmware or attempt to add a CSC could it cause issues? Is it likely the previous owner was just a tinkerer? Am worried If I add a CSC my phone may become blocked or something but If I don't I can't use my Gear VR
Any help or advice greatfully received.
what software version is on your phone ?
It looks like someone may have have upgraded your phone to nougat beta or a custom ropm. Nougat beta does not have a csc associated with it. You need to flash one after installing.nougat beta.
I suggest you ddownload one for your provider from samfirmware or contact the sellor and try to find out what was done to the phone.

The previous owner has probably installed a custom rom and that's why the csc is missing. If you don't have root, then I would recommend for you download the stock firmware and flash it with Odin and that should fix your problem.

Please see attached for the software info, does this looks like the beta? Thanks for the replies both, I'll look into this Odin and see what it's all about. I haven't done anything with firmwares for years, not since messing about with Nitdroid on my old Nokia N9, hopefully can still get to grips with it all!

Nope. not nougat
You can download full rom and flash through odin. Make sure you flash all 4 files (bl,ap,modem and CSC).
Here's what I thought happened.
Previous owner root phone(cause knox 0x1)
and probably update the firmware by flashing rom though odin or use custom rom. But he/she didn't know how to flash the full firmware though odin properly(or just don't want to. idk) because of the old modem(baseband APEQ) but new rom file(build APG3) and also missing CSC.
These probably mean he/she flashes only AP files(rom) in odin and ignore the other 2 files(modem and CSC) and might also bl file(bootloader).

Yeah that sounds very plausible, just can't imagine why they would root it and update firmware but not do it properly, every guide I've read directs you to use the appropriate CSC for your country. Well I've got Odin running as we speak, so fingers crossed I can get this working and that I'll be testing out the VR as soon as possible! Does put me off buying second hand in future, but I guess on the plus side at least I don't have a warranty to worry about and can have some fun with different firmware.
some small 3 rd party providers or regional area have csc which are not commonly available, so when you upgrade you would not want to touch the csc.
The sim you are using may not recognize the csc the previous sim card was using that is why it is giving you there error message.
Could be that, guess we'll never know.
As mentioned above I have flashed with the latest firmware and updated the CSC, fortunately it's all working now so thanks for all the support. My refurbishment check now shows as attached.

OTA android 7 update for g935fd not working

Hey guys,
The OTA update for android 7 has come up in my s7 edge duos. I have tried downloading it twice........it gets to 100% and says there an error and that it's the wrong version.
Not sure what to do.........any ideas
Download and flash the rom through odin.
Did you ever flash a different rom? Which brand is respectively CSC has your phone?
Never flashed another rom........bought the phone off amazon.com............it's zn international version, but looks like the supplier got them from UAE.

the supplier may have gotten from UAE but the csc may not be from there.
you can try downloading the Rom from samfirmware and flashing that way.
Thanx for the reply guys, how can I find out the CSC on the phone? Also if I flash with odin, Will that erase all the data on the phone? And will it trip the knox?
Why is it that the update doesn't work? How come the software on my phone doesn't match the update it's downloading? Is it something the supplier/seller has done to the phone? Like modify the software?
Thanx guys
Install Phone INFO ★Samsung★ and you get all necessary information.
If you flash with Odin Know won't be triggered. You can keep your data with the three following requirements:
- The firmware you flash must have the CSC included you use at the moment.
- You need to use HOME_CSC file instead of CSC file.
- You may not tick re-partition.
Keep in mind to only flash firmwares designed for the Exynos variant.
Sellers on Amazon sometimes get phones from a different market and flash then a firmware fitting your market. This is rather a replacement than a modification (since the whole system is still official) and Knox is not triggered. However, one effect is that OTA may not work or gives "phantom" update notices. There's no restriction aside of that and you can just use Odin to remain updated.
You can post screens from all pages of the app I mentioned and we can see what's going on.
Hey Andiling, really appreciate your help pal. Here are some pictures you requested. Thank you
