Changing CSC code from a different model number - Samsung Galaxy Note 20 Ultra Questions & Answers

Hey Guys, I am in desperate need of help.
So I bought the note 20 ultra (model N986-U) from a seller in Texas (I live in Canada). The phones original csc code was ATT/ATT/ATT. I have a rogers sim card (csc code RWC). I noticed the phone is still stuck on One UI 2.5 because I am not connected to the ATT network.
So I tried changing the CSC using SamKey. I bought some credits, followed the steps and now for some reason my CSS is XAA/XAA/ATT.
I understand now that my phones model does not have a RWC firmware. Frija can't find the software for the SM-N986U running RWC but has no problem finding the software for the SM-N988W running RWC.
Is there any way for me to update my phone without bricking it? In an ideal world I would get OTA updates. Can I download the CSC_HOME file from the SM-N986W and flash it on my SM-N986U?
I'm really sorry for the noobish questions, I read so many threads and watched so many videos but I don't have the balls to experiment with such an expensive phone.

I know you can flash U1 firmware on a U device without any issues.
That's what I did to mine.
As for flashing W software on a U/U1 device, it's technically possible considering they are identical hardware, but I cannot say for sure what impacts it might have to the phone's performance.
You can always manually flash current U firmware.

Hey thanks for the answer,
I ended up flashing the W firmware on the phone and it worked flawlessly! Now the phone shows that it's a model N986W. OTA updates still don't work tho, even though the csc shows RWC

Glad it worked. Grab the latest firmware for RWC and then wait for the next update. (N986WVLU1DUB5)

Possible to convert flash SM-G930U firmware on a SM-930P?

Hey guys!
Yesterday I got a Sprint carried S7 SM-930P as a gift. The only problem is that although it works flawlessly on my sim cards (I'm not in the US), I found out that the 930P won't get the 7.0 update. Is it possible to flash the G930U firmware without messing my phone up?

I wouldn't do it unless your absolutely sure, I wouldn't be so sure if it's for a different model number. If they were able to have the same firmware flashed Samsung would just release it, they obviously didn't because it requires extra effort, pointing towards the conclusion that the firmware is not flashable on 930P

You can flash it, i have done it myself. There are many guides over here that tell you how. All S7s in the USA are the same exact thing hardware wise, only the software (firmware) is different. Am currently running SM-G930U firmware on an SM-G930VL S7. @op the sprint s7 (SM-G930P) already has android 7 as of last 3 weeks

SM-G930P converted to SM-G930U
Hey guys. I was able to flash the sm-g930u firmware downloaded from sammobile... the problem I have now.. I have a blank csc. No product code.. and on software updates it fails to register my device. Also in settings . I have some weird options. Which some of them are repeated. I will upload screenshots.. Also there's a system UPDATE option and also software option. Which one of them fails to register and the other only works with Wi-Fi. Should I revert back to my stock sprint firmware. If so do I need to wait for a firmware with same build date or newer. Because on sammobile haven't uploaded a firmware with a build date on par with the current install. Then I would have to wait right. ? If using a older firmware it will brick or do something to my phone ?​

Did you flash all file in the SM-G930U folder (AP,BL,CSC,CP)? Because i did it with T-mobile,Verzion an it work fine
Thanks for the reply. Already solve.. what happen i flash home_csc. So ir was like that. But then i made a back up.. and flash again using the csc file. And all work perfect. At first phone was with the SPT csc.. then after i restored phone and pop in my sim it did something.. and now I'm with XAA csc. Works perfect. And could receive updates (phone registered). Just waiting for the july security patch update. Btw phone works better in every way.. battery even last longer..

Hey Buddy. I would recommend doing a full back up on your phone., using Smart Switch app
It saves all your numbers, message, etc..
Then proceed to flash the latest firmware for the Region or Provider. Using (CSC) not (home_csc) which means flashing the csc will wipe your phone data. Phone will be like new again. Proceed tru set up. Loggin in gmail. Proceed to update smart switch app if not found in apps. Then restore from the back up file. And good to go.

actually all S7 are not the same hardware fyi. The Sm-g930p has chipsets snapdragon and uses cpu procesaor quad core but the sm-g930F has the chipset Exynos8 cpu is octa-CORE the chipsets vary from these two. Flashing firmware for one chipset to the other may cause major problems bot to mention bootloops.. but I looked up sm-g930U and it uses the same processor as the P model.snapdragon

He said all S7's in the USA are the same, which is correct. Exynos/930F isn't sold in the US, only way to get one is to grey import.
You can flash any USA model's firmware onto any other USA model because they're all the same hardware.
anyone running the 930p with current update how did you get around the binary 6 lock all the 930U firmware versions I can find are binary 4 I think t-mobile is 5. Anyone got links to a firmware we can push to sprint variants that are binary 6.

You can't get around it. It is currently impossible to "downgrade" the bootloader binary version. All US carrier variants are version 4, except Sprint that is 6. You are stuck.
The only way it would ever be possible is if (a) one of the carriers, in a future software update, increases their bootloader version to 6, or (b) if someone figures out how to unlock the bootloader for the Snapdragon models.
Neither of those options is likely to happen, ever. You might get lucky and hope the G930U unlocked version has a higher number (it hasn't been released for Oreo yet), but I wouldn't bet on it.

Blame Sprint; there is really no reason for them to do what they did except keep users from switching their phone to another carrier. This isn't a Samsung thing. I don't believe you would be able to do this with any other Android phone, either (i.e. go backwards in bootloader versions).

SM-G930V purchased in Australia

Hi All,
I have a moderate experience in flashing firmwares and modding my samsung devices over the years.
I have recently purchased an S7 which is unfortunately a SM-G930V model, i thought it would have been the SM0G930F which would have made life much easier.
I want to know if it is possible to get the original Australian firmware or even generic stock firmware on this device?
My issue is with the network settings where i have manually put in APN settings my match my carrier and 4G coverage in australia.
If not am i able to just flash a different baseband to this device preferably Australian?
I have read that flashing a different model firmware will soft brick the device, i just want some insight before i start breaking things, also what are my options.
Much appreciated, thanks, Will
You have the snapdragon s7, you can't flash the exynos 930f firmware on it, you can only flash the american firmware. You might have luck with the 930u unbranded firmware just do some research on it.
Thanks mate,
I'm going to flash this firmware using ODIN, do you know if it will be successful?
https://forum.xda-developers.com/att-galaxy-s7/how-to/xda-community-love-g930u-t3415875
not sure how to check my bootloader version etc
No clue, goto the verizon subforum and see if anyone flashed the 930u firmware on their 930v.
Just tried to flash the firmware to my phone and recieved an error, the phone is now stuck at download mode with error:
sw rev check fail : [system] fused 3 > binary 4
this means the bootloader won't accept the firmware?
LOL, guess ill try another firmware.. Any ideas?

Galaxy s7 "updates software" option missing

Hi, I have just bought a brand new galaxy S7, model SM-G930F.
Although it is an international model, it carries a snapdragon 820 processor.
I am told , that it is a USA model, built under Verizon.
SM-G930F is supposed to be a global model with exynos, does anyone knoes what is the phone I bought?
Anyway, my real problem is, that the "updates software" option is missing, in "about phone" list.
I am stuck in android 6.0.1
I checked it is not rooted and it must be a genuine phone.
Can anybody guide me through solutions?
I would really appreciate any help.
Thank you
Moving to general S7 Q&A since you say it's a SM-G930F.
Check the back of the phone and verify the phone model. You should be able to update through other options like Kies, unless they've changed that recently.

It's not a G930F if it has a Snapdragon processor
Commonly faked to look like G930F by editing firmware / stickers / model numbers etc, more likely to be the G930V if it's Verizon
Boot to download mode and check the model number in there, that's the only one that can not be faked
(Volume Down & Home & power)
And they likely removed the update option from settings to prevent any problems of the phone updating to either the wrong firmware, or removing their fake edits with a V update
Flash the proper firmware with ODIN 3.12.3 or newer from updato.com once you know your model S7
Galaxy s7 "updates software" option missing
Dear Durham,
Thanks for the help.
Yes, you are right; it is G930V.I have been tricked...
I have visited updato.com and found 12 variants of S7 firmware.
My bootlader version is - 6.0.1 November 20, 16 USA (Verizon) (VZW) G930VVRU4API3
Shall I download and install this one and afterwards make a manual software update or
shall I install the latest - 7.0 August 25, 17 USA (Verizon) (VZW) G930VVRS4BQH1 ?
After successful installation, will these firmware fake modifications( to G930F) disappear permanently?
I am much obliged
Thanks

The ROMs from updato.com are full ROMs so you can just flash the latest / newest one and you'll be 100% up to date once it boots
Use CSC and not HOME_CSC though as you are going to want to reset after the flash to clear any hacks from the previous ROM (This will wipe the device so backup any important files first)
CSC, AP, BL and CP
Yes this will permanently remove any modifications from the faked ROM
Wish me luck, I will give it a go!
You have been most informative, many thanks.
Good luck :good:

The good news is that the verizon edition can be rooted and is network unlocked from the factory so as long as ure carrier supports the bands it will still work for you on a side note flash the u firmware not verizon and u wont have any verizon bloatware out of the gate either
Mad scientist, thank you for your intervention.
Just to be clear, which firmware do you suggest me to install, not the verizon G930V?
Could I install the G930F for my country (Europe).
I thought they are incompatible...
As my bootloader version G930V I think I would better stick with the V version.
Are you suggesting not to upgrade to nougat and reinstall factory installed 6.0.1 and better wait for 8?
Yes you are right, I am not good at twiking.Will I have drain baterry issues with nougat?
Dear Durham,
Emergency help!!!!
I installed it succesfully but now it does not recognize my sim card, as it is from a non USA country.
Should I reflash a different firmware? F or U ?
I am from Greece
It seems to be working...
The Verizon logo appears upon starting the phone
But in language selection, there is only English and asian languages available.
Software update finally appeared.
In order to have my langage back, should I reflash with the U ( unlocked version) or the F (global)?
No mobile data.
Maybe I am calling through Verizon.Roaming.Expensive.Scarry...!!
He means that the G930U firmware will flash fine on the G930V, it is the same firmware but without the Verizon bloatware added
You can not flash any other firmwares, it just happens that those two are compatible with each other
Flash straight to the latest
So I shall flash the G930U?
Will my sim card be recognized and mobile data be active.
Nougat 7 or MM 6-your opinion, again?
thnks
No idea if your SIM will be recognised, but if it's not working with the V firmware it's worth a try
As I said, flash the latest firmware which is Nougat
Personally I would be contacting the seller and asking for a refund / exchange for a real G930F that you paid for
firmware
I tried, but he is not cooperative.
How about F version-it worked with it before ?
(only it was modified with the dissapearance of system update.)

No you cannot flash any other model firmware, that was NOT the G930F firmware, it was a hacked / faked U or V firmware
I think you better read a good few threads before going much further or you're going to end up with a brick
Contact the seller and request a refund
Don't suppose you can flash CSC files of the 930F on 930V?
Dear all,
Thank you for your help and interest in my problem.
This is indeed a great forum!!!
I tried to flash the F version, but thankfully odin stopped it from the beginning, presenting "failed" message.
I suppose if it continued, I would end up with a brick as Durham suggested.
Finally I flashed he U version, as mad scientist suggested, and up to now it works like a charm.
As Durham advised, I used CSC and not HOME_CSC and the hack was eliminated.
Sim card is recognized, no bloatware and mobile data working.
Let's hope it will continue like this...!!!
Only glitch, not everything is in my home language ( message icon name and in settings-the menu options-any idea how to fix it? - I removed english and left only my language as selection, but onle these remain untranslated)-small problem
I have learned a valuble lesson from my adventure.
Ebay, an organized platfrom may it be, it cannot control each individual's deceivals, so one must be extra wary when buyng from unofficial sources, nomatter good reviews from others...
Thanks again to you all for your help, I would be in serious position right now, if it weren't for you guys.

*UPDATE* Bootloader v3

Just FYI, it appears with the new Blv3 firmwares, the device will only accept official firmware. Meaning, no more flashing U1 firmware on the carrier models, or vice versa. No more flashing U or U1 firmware to the Canadian W models. Flashing between carrier firmwares is fine as long as it's on a carrier branded device (running TMB on a VZW device, etc). But running 950U firmware on a 950U1 will result in a brick, that is this far unrecoverable.
If your currently are running U1 firmware on a U device, vice versa, or running W firmware on a U or U1 device, or vice versa, you need to flash back to the firmware version that shipped with your device BEFORE you accept any OTAs that take you up to Blv3. Currently the S series is still on BlV2, but may go to Blv3 like the Note series just did.
This has been tested and confirmed.
Credit goes to @me2151, @FatalONEM8 for discovering this and warning people. I didn't find the issue or test, it just passing on the info to hopefully save some bricks.
Update from @mweinbach:
"EDIT: After being tested by XDA Senior member me2151, it turns out cross region flashing does work. Prince Comsy Odin is working, but we can not test if the factory binary flashing will hard brick your phone. So flashing US unlocked onto a US carrier device should work."
To expand a bit on what @mweinbach*just said, @me2151*did some more testing, and he was able to successfully carrier switch from a 950U to 950W using Comsey ODIN. So it looks like Comsey ODIN is not patched as we originally thought. Not sure exactly what caused the tester's phone to brick, but it HARD BRICKED and had to be RMA'd at his expense. So we jumped on the forums here to warn others until more testing could be done. @mweinbach*wrote the article and @xdanilvaand I began posting here.*
We may have overreacted, but wanted to err on the side of caution to protect people from hard bricks.*
The Blv3 factory binary has not been tested, so still unsure if/how we will be able to use it, or if it will cause issues.*
For now, carry on as usual, but understand we still don't know the full implications of the Blv3 patches. One person has already HARD BRICKED, and @me2151*almost hard bricked testing all of this for us.
There is currently a group working on a fix for bricked devices, but for now consider it a hard brick. Don't chance it.
Is Oreo for the S8/S8+ a Blv3 firmware or is it BLV2?
just curious as I flashed my Verizon branded GS8 to U1 firmware to take the Oreo beta..
So If I own a Sm-G950U1 but I have been running G950U Tmobile Oreo beta and upgrade to the stable oreo I'll brick my phone? In order to prevent this I'll have to first go back to G950U1 on nouget and then go up to oreo?
I don't really want to do this because I am loving using the T-Mobile variant because it gives me multiuser (digits) since it's built in.
Does the same apply to exynos devoces?
As far as I know, if you are on the Oreo beta, at least on the Snapdragon US variant, you are still on v2 (the number after the U in the build number is the bootloader version). Do not accept any OTAs and only update if you are completely certain you want to be stuck.

Does this mean that we can update to a build with Bootloader v3, but don't expect to be able to change carriers afterwards? For example, I switched my S8 from ATT to XAA to get rid of the bloat. Should I restore to ATT on Nougat or can I stay on Oreo beta on the unlocked U1 firmware?

You can stay on the unlocked firmware for now, but once you switch to one of the carrier firmwares with v3, you cannot go back to anything other than a carrier firmware with v3. You should be ok for now, but just be sure that the next time you update that it is not on v3 or you'll be stuck permanently or until a fix is found.

My question is I have an ATT unlocked device on Cricket Wireless running the oreo beta since I flashed it to unlocked firmware. Should I revert back to Nougat before the final oreo build or just stick with it?

There is not.
And I haven't personally tested it, but Comsey is required to flash U1, so we know it will brick the phone once it does reach Blv3.

No on a U1. They tried to carrier switch on either a U or a W.
Ok... so they tried to go from a device running a Carrier fw on blv3 to... what? A carrier fw on blv2?
I know this is still early, but the more questions and answers I see, the more confused I am.
Do we know if all of these scenarios will have the same result?
a) I have a AT&T (950U) branded device. I flashed it to become unlocked software (950U1). The device currently updates OTA with unlocked updates. A BLv3 OTA will brick the device. True/false/not yet known?
b) I have a AT&T (950U) branded device. I flashed it to become unlocked software (950U1). The device currently updates OTA with unlocked updates. Assuming a) is FALSE. Device will operate as normal U1 phone, but I will never be able to put 950U carrier branded software on it (via modded Prince Comsy), because that will brick it. True/false/not yet known?
c) I have a AT&T (950U) branded device. I flashed it to become TMobile (950U) device. It now get updates via Tmobile. Future OTAs will continue as normal and I can even use Odin to flash other carrier software (950U), but I can NEVER use modded Odin to flash unlocked software (950U1)? True/false/not yet known.
Based on what I've read right so far. It seems that the answers all remain theoretical, thus not yet known, but based on the Note8 update, the answers would be a) False. b) True. c) True.
Am I far off base???
The thing right now that I understand the least is the scenario a). I don't understand why if I have a phone that was 950U but is now 950U1, why it would get bricked. I do understand that attempts to change it once BLv3 hit are currently DOA, but that's different than simply keeping your phone in the stream that it is currently.
There are some good questions in this thread, I realize that its an evolving situation... So I have to ask directly... I have a Verizon branded 950U that I followed https://forum.xda-developers.com/galaxy-s8/how-to/snap-guide-flashing-standard-fw-carrier-t3625817 to switch to XAA and flash the U1 firmware, and I have taken part in the Oreo beta.
Currently my phone has Baseband Version G950U1UEU2ZRA8. There is an OTA update pending right now that is G950U1EUE2ZRAE/G950U1OYM2ZRAE/G950U1UEU2ZRAE. From what I understand, and what I am reading about this BLV2 vs BLV3 issue, based on the numbers in this, if I take this update, I'll still be BlV2, and be ok? If I should want to return to stock Verizon firmware, I can still do it safely?
What I am unsure of is.. If the phone gets updated to BLV3 while I have the XAA/U1 setup on my Verizon branded 950U phone, will I still be able to flash back to stock Verizon, then just not change to anything else? or once I get on BLV3 I am stuck with whatever firmware I have on the phone? Or is that part still unknown for sure?

I am basically the same as you except AT&T beginning rather than Verizon. I currently have the ZRAE Oreo beta software running on my phone. Based on everything said so far, there is no danger yet in downloading that OTA because it is still BLv2. The danger would be if the final Oreo version drops with BLv3 and you apply it. Then we're left with these different scenarios that are still being figured out.
Absent any concrete info, I'm going to just avoid the Jan security patch on my Note8.
If I have to flash back the Verizon software to have a non-brick device, well I'll just sell this thing and buy a cheap unlocked phone with microsd, wireless charging and a nice screen.

Question Change Service Provider Software

Hi all,
I bought this phone from my friend who was using it on ATT. It is global unlocked phone and I activate and register, change new 5gsim and no problem on Verizon Network.
It is working and fine but, it shows ATT logo when phone is boot up and still it has ATT bloatware.
Under the Software information > Service provider software version is showing below
SAOMC_SM-F711U_OYN_ATT_RR_0016
ATT/ATT/ATT
SO THIS PHONE IS legit!! even Verizon told us. They did everything with me for 3 hours. wow!
Anyway, I think it's the problem of other carrier's software is in
Do you guys know how to change provider software to Verizon? should I contact Samsung??
Please help me.
Thank you!!!!!!!!

I found solutions and flash the firmware with Verizon userdata, but, still shwoing everything on ATT. Not Verizon.
I even flash with factory reset. Yes, I used Odin 3.13.1b patched and it passed...
Do you have any idea?

Try google to search for a different csc. After that I don't have a clue...
I got it working. Thank you. your "Flash a U1 software and VZW userdata." help me a lot.
I did find out good firmware and software at Sammobile and now everything works as Verizon.
Thank you

@iHeartslutsz https://www.sammobile.com/samsung/galaxy-z-flip-3/firmware/#SM-F711U1
Whenever I flash a new software through Odin after downloading it from Sammobile, the Dark Side RC theme (I think it's related somehow to the so called Star Wars special edition) for samsung, comes as one of two default themes into the system and can not be removed. Hence, even I change the theme from setting, this iron head appears everytime I restart the phone for a few seconds. So I tried different firmwares for my country but nothing changes. So someone from another forum said that my service provider software version differs than theirs. So in short, how to get rid of this silly iron head? Any help would be appreciated.
change csc, use SamKEY (paid) or SamFwFRPTool (free), then flash frimware you need with odin with CSC file (this will wipe your phone and reset to factory), not use home_csc in odin

Thank you. I downloaded totally different firmware files with different CSC code and the problem has solved.
SamFwFRPTool is a tool I use to change my CSC software channel. The way I understand it you need to change the CSC in the program before flashing the u1 software on it so you get a full unlock as opposed to a partial one.
I might be wrong here though so don't take everything I say as being true.
