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 )
UPDATE: Also my carrier works.......
PLzzzzzz Help......

A bit silly question but have you tried installing from Smart Switch? You mentioned Odin so that didn't look promising...
Try recovery from Smart Switch.

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

CSC Version :

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?

"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.

Make sure you have the csc ready to flash if it doesn't work . It shouldn't break anything as such but to be on the safe side . Plus it goes without saying I'm not responsible for anything that happens to your device as a result of this .

Can flash everything from stock rom except BL

Hi,
I had installed the Helios Rom on my S7 Edge G935FD
I wanted to revert to the stock rom, but in ODIN, it was always failing.
After several tries, I could flash the Stock ROM G935FXXU1DQAZ_CL10273029_QB12312524, but keeping the BL unchecked.
Whenever I try the BL, it fails.
I have flashed the ROM, it Starts, but the SIM is not recognized.
Please HELP!

May be its because your are flashing old BL over new BL which is not possible. Always download latest firmware for your region from "samfirmware" and try again.

I have downloaded the latest version of the firmware. I just can not flash the BL..

I have the same issue. Cant connect to mobile network and can't flash BL.
Please help someone.

Ok check Sammobile for a BL Version 2 because, as said before a BL downgrade is not possible at the moment. Not all countrys and carrier have all Versions with BL2.
Her's an example:
G935FXXU2ERE8 <-- BL 2 Oreo
G935FXXS2DRDI <-- BL 2 Nougat
G935FXXU1DQJ1 <-- BL 1 Nougat
I hope that helps to download the right version.

And having read ur soloution, I now have even more knowledge 2 add to my rooting knowldge database.. So thx so very much 4 ur post. And just in case u or mayb someone else might need this info, here is where the (SAMSUNG USB DRIVER) can b found: (https://samsungusbdriver.com/download/samsung-driver-v1.5.63.0). Hope someone findz this info useful. Peace 2 all:good::fingers-crossed:

S10+ G975U want to remove ATT bloatware.

Hey there. My S10+ G975U is running G975USQS4DTF6, One UI 2.1, wanna flash unbranded.
Tried a couple tutorials from here but nothing has removed the AT&T bloatware.
Familiar with flashing, odin, combo files, etc.
It's my phone, completely accessible. I just want to remove the system hog bloatware.
'preciate it!

Just flash an G975U1 ROM and you will get rid of those bloatware

Thanks for your responce!
So have to root/unlock flash custom recovery first? If so I haven't found instructions for the US AT&T model.
Any advice much appreciated.

Tried two firmwares with odin 3.13.1, 3.13.3, 3.14.1 patched
G975USQS3CTB6_G975UOYN3CTB6_TMB
G975USQU1ASBA_G975UOYN1ASBA_USC
Always either SH256 SW and/or SW REV CHECK FAIL.

Tried another couple firmwares with odin 3.13.1, 3.13.3, 3.14.1 patched....
G975USQS3CTB6_G975UOYN3CTB6_TMB
still Always either SH256 SW and/or SW REV CHECK FAIL.
also always abl.elf, xbl.elf fail in Odin.
Should I use mount the Userdata? I think i've tried both ways and they fail. Ugh, losing track of what I've tried now.

I did this a year ago when I first got my S10+ Verizon and flashed the unlocked rom on it.
I believe that there's a modded version of oden here. Find it and download the latest original unlocked firmwear and you should be good.
No root and nothing

Downloaded the most recent through Frija for CSC "USC" and "TMO"
Tried flashing with Odin modded and regular. abd 3.14.4 now.
Still keep getting SW REV CHECK FAIL " [ab1]Fuzed 4 > Binary 3"

Also, the I've noticed sometimes HOME CSC is used or included when other times regular CSC is.
USERDATA is sometimes not used, what's up with that?
Thanks again for any more leads. I keep flashing and wishing lol

There are two very similar models: 975U and 975U1. The one ending in U1 should be unbranded.

I need to unlock bootloader?

Recently tried both:

SM-G975U_1_20200610113004_mh0r74212v_fac
Both from Frija
Is that 1 in the middle correct?

Which version number of Odin is for S10+ Android 10 i guess would help narrow down my problem too?
Besides the firnware Odin has to match too right? Or can you just use the most recent version for any earlier firmwares too?
Added screenshots from Phone Info SAM
It comes down to confirming exactly which firmware is needed, version of Odin (modded or not), which CSC to put in(CSC or HOME) and is USERDATA necessary too?
Thanks again all!!!

Most of your questions can be answered here. https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
You can flash any Rom (V, ATT, or anty other American Rom) you want as long as you don't go backwards on your bootloader version. The version # is the 5th from the last digit on your baseband #. I flashed a U1 rom on Verizon bought S10+ and now get updates straight from Samsung with no vendor apps at all.
