Some questions about Firmware update

Hi,
I want to update my phone to Official Android Lollipop v5.
Can i install any other country's firmware on my device?
If yes then 'll this void my phone's warranty?
Can i get official updates in the future after upgrade*using other country's firmware?
Which firmware/update you suggest for my device?
If any problem occours then can i degrade back to previous version of android?
Here is my phone info.
Device: SM-G900H
Product ID: SM-G900HZDAPAK
PDA/Phone:*G900HXXU1ANG3
CSC: G900HOJV1ANG1
Thanks,

Try installing KIES3 and connecting your phone to the PC to check for updates
If none, grab a stock ROM for your model S5 from sammobile (No links allowed on XDA)
If the ROM is a stock Samsung ROM, it will NOT void your warranty so long as you use ODIN to flash it
Yes you can downgrade again by the same method
No idea about OTA updates, you'll likely end up with OTA updates for that countries ROMs
Any country ROM will work, but you might have issues with network, must be for your model S5

[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?! I just flashed the stock firmware without rooting it or anything.What can I do?

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.

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).

Can i install 935F stock rom on 935FD Device.

hello, i am from India. I recently bought a new Samsung Galaxy S7 Edge Duos. FEW DAYS AGO (ABOUT 2-3 DAYS) i updated it to latest version over OTA. I tried to root it by CF Auto root but something broke and it transferred my device in bootloop so i downloaded and flashed a stock rom G935FXXU1APB6_G935FOLB1APB6_XSP_FULL using Odin. My device started but i figured out that the rom is Singaporian version and its a March upgrade and i could not update it also. I am also having wifi connectivity issues. My old rom was perfect. It was preinstalled by Company. Please help me or please give me a link of my model's official stock rom rather than Sammobile ( i tried sammobile but my connection refuses and also speed too low )

Download and install USB drivers for Samsung Galaxy S7 edge in your computer.
Make sure to take backup of any important files on your smartphone.
Enable USB debugging option by pressing Menu > Settings > Applications. Navigate and tap on Developer Options to ensure that USB Debugging is enabled.
Ensure that your Galaxy S7 edge carries more than 70% of charge.
Highly Credible Leak Points At Early Samsung Galaxy S7 Launch Date
Unzip Odin on your computer and install it.
Unzip firmware zip file in the same folder as Odin.
Switch your Samsung Galaxy S7 edge off and boot it in Download mode: press and hold Volume Down and Power together and then press the Home key. OR, check how to enter Download Mode.
Open Odin and connect your smartphone with your computer. When connected successfully, one of the ID:COM boxes will turn yellow with the COM port number after a while. (In case you don’t get it, try another USB port. If that doesn’t help either, then re-install USB drivers).
On your Odin, select files:
Click on AP and select file with AP in its name.
Click on CP and select file with MODEM in its name – ignore if you didn’t get any such file.
Click on CSC and select file with CSC in its name – ignore if you didn’t get any such file.
Click on PIT and select the. pit file – ignore if you didn’t get any such file.
Click on BL and select file with BL in its name – ignore if there is no such file.
Make sure to check Auto Reboot and F.Rest Time. Check Re-Partition only if you selected the. pit file.
Click on Start to initiate the update process.
When Android 6.0.1 Marshmallow update installation is successfully completed, you will get a PASS message.
I don't know if factory reset is necessary after flash, but I did it, just in case. I attached Odin which I used.

Unless you know what you are doing and about files source/files you are flashing, then not much.. but if you are not sure, then Smart Switch can download official f/w for your specific model & flash it for you.. simplest, no brainer to recover to official f/w.

Official Android 7.0
Hi
I have G935FD device, which I recently bought (the second hand one).
I notice that I have issue with GPRS data transfer... it looks like, from time to time when GPRS is active SMS sending is not possible any more (up to next power OFF of device) .
At that time I'm able to see only one GPRS range indicator.
I'm able to receive calls from both SIM cards.
I did not check am I able to call from both of them.
According to my google investigations issue is pressent in Android 6.0, which I have right now.
Case shall be easy, I need to update to Nugat verision and it is all , but...
1) If I'll check firmware update on my mobile I have inforamtion that it is the latest version of firmware G935FXXU1APD1// G935FXXU1APB6. what is not true
2) I started to looking for official Android 7.0 version. to get it, I have to have CSC code. Phone info application have cleared out all CSC code. *#1234# don't work - "error message connection error or wrong MMI code".
Device type is hero2lte
Product name is hero2ltexx
Product code is SM-G935FZSU - this looks like oryginal information .
Bootloader : G935FXXU1APB6
PDA Version: G935FXXU1APD1

Does any one know what can be the oryginal CSC code for such device?
Can you tell me where can I find oryginal Android 7.0 which will works fine in Poland ?
Thanks in advance.
Hi
Below information for anyone who have the same issue as I.
I download the newest official ROM for Android 7.0 for Poland (G935FXXS1DQHI).
I used ROM for single sim, not dual sim.
Since that I don't have any issue with SMS or GPRS any more.
MMI codes started to work back.
I still have dual sim .
Simple , now it works better !!

I got a used GT-935T phone very recently in India, which was still running android 6.0. On browsing these forums, I found out that we could flash stock rom on it without rooting, so I did so using Odin. I flashed the stock rom of Android 7.0 for t-mobile 935T, which was what my phone was supposed to be.
On further browsing, I also discovered, that we could flash any stock rom on the phone, irrespective of the region. So I decided to download the latest stock rom for India 935fd. I did so, but whenever I'm trying to flash it using Odin, I'm getting an error - repartition failed.
I've not checkd the repartition option.
can someone help me?

Verify Original Samsung ROM

Dear all,
I own a Samsung Galaxy A3 (2016) with the following informations
CSC A310FB2X2APD2
Baseband A310FXXU2APC5
Current software A310FXXU2APDA
The phone was provided with a car type Seat Leon Connect which supports Android Auto. I live in Germany. As you might recognize, the CSC code B2X is a bit uncommon, but related to the "Seat edition" of the phone.
Now I have the problem that the phone is on a quite old software version (Android 5.1.1 with Security Updates of May 2016) and the phone does not find updates via OTA or Smart Switch. Several calls to the provider (Seat) and Samsung revealed that there is confusion how and when the last updates that were published for the A3 (2016) series will arrive for that specific model. As the phone provided has a Spanish country code, I was finally forwarded to Samsung Spain who told me I should simply search for updates. Which I obviously did.
As Samsung Germany told me that a spanish model would only do OTA updates when having a spanish IP, I even used a spanish proxy to look for updates, but without success.
I tried to change my CSC to the german DBT using the *#272# command, but it just tells me that the command did not succeed. There is an app called "Phone *INFO* Samsung" that tells me my CSC is E01 where E01, E02, E03, E04 and E04 are available in the firmware. This is confusing since this "E0x" is no known CSC country/provider code. So no way to simply switch the phone to DBT and german software updates.
I have the feeling, I will never be able to receive official updates...
So I have a couple of questions:
I'm coming from a Windows Mobile 10 phone where updates came nearly on a monthly base. Plus, the platform was never subject to hacking attacks due to only few devices. How critical is it to stay with the old software from a security point of view? Note, I only download software from the Play Store, but I am surfing the web a lot.
Is it true that a spanish IP is required for OTA updates or Smart Switch to find the update for the spanish phone?
As it is likely that I won't get offcial updates, I am willing to flash the german DBT firmware of December 2016 (say, from updato.com) using ODIN. Will I be able to receive OTA or Smart Switch updates in the future based on that, and therefore stay on a regular update path? I read that CSC and/or product code may be an issue.
Is there a way to ensure that the firmware I download from updato.com is really the official firmware? I am very sceptical about security and modified ROMs as I use the phone for business purposes. I informed myself a bit on the KNOX software installed on Samsung phones. Is it right that KNOX is able to check the originality of the firmware being flashed and therefore should increase the "Warranty void" counter in case the firmware is NOT original? Is there another way to check originality in advance before flashing?
Will I have to care for changing CSC and/or product code after flashing?
Most important: Say, I do the flashing to DBT firmware and for some reason, I need the original firmware back. Is there a way to return to the original Seat firmware? As it is available nowhere for download, I would have to use Smart Switch. Will I be able to connect the phone and simply put it to factory state (including the CSC code)?
Sorry for this long list and possibly dumb questions, but I am really unsure how to proceed.
Thanks for helping!
Tobias

Hi tys0n,
yes, it is exactly the same version.

Here's the firmware. http://updato.com/firmware-archive-select-model?record=528B238FC03811E6B04AFA163EE8F90B
NOTE: U2 (marked in red) is the binary number. Bootloader should also be U2.
Since this seems to be a very specific firmware I just want to give a little varning.
Don't update to U3 if you ever plan to flash back to any U2 firmware (including this one).
Updated bootloader to U3 won't allow downgrade of itself to U2, and old modems won't work with updated bootloader.
There's a good chance that you'll end up with no signal or lost imei if you try to downgrade from U3 to U2.

Hello,
I'm also exactly on the same situation... does anyone found a solution to upgrade to latest Android version / way to proceed ?
Thanks

The " Device 7 Binary 6 " error means that this version of firmware that you want to install has an older version of bootloader. and by installing the wrong firmware, that means your bootloader version has changed into a new one, maybe the newest by now. What your phone is trying to say in other words is that you can't downgrade your bootloader.
Explanation for what I wrote above is quite simple, ignore the last 4 characters on each version that you posted here, and you have: G935FXXS7xxxx and G935FXXS6xxxx.
Using TWRP is the best way to avoid the problem of different versions of bootloaders.
Though, you shall wait for samsung to upload a newer version if you trully wish to have your phone stock 100%.
