Hi everyone
What's the best way to change my CSC to BTU (from EVR)?
I've done a little research and found the following:
1. Root using PingPong to prevent KNOX trip
2. change CSC using an app (is this available for S6 in the app store?)
3. flash with BTU firmware and unroot
Is any of this possible, is there a better way?
thank you.
Yes, its possible while your still on 5.0.2.

Thanks roydok, whats the best app in the store to make the change as there are so many to choose from?
Also is there a simpler way, or is the way i described it the only option, esp for KNOX trip?
I've seen some other tutorials use the auto cf root way, is that ok to use or does that trip KNOX?
Lastly, if i move to BTU and update to 5.1.1 will i continue to get OTA updates direct from Samsung rather than my carrier?
thank you.

As far as I am aware.. your csc will change by flashing btu... your root obviously be gone too. If you flash 5
1.1 you loose root but you'll gain ota from samsung rather than your carrier. Hope that helps
Skip the rooting and just flash the btu firmware from Odin. That will change your CSC anyway.
I was on vau firmware but changed to xsa using this method.
Just be sure the btu firmware us for the same variant of fallacy s6 as your device (I.e both 920F or whatever you're rocking)
EDIT
To get btu system updates going forward you WILL need to factory reset after flashing the btu firmware as your device needs to re-register with that CSC. There might be a way to force it to do that without a factory reset but I dunno how. So perhaps use smart switch or Helium (from app store) to backup whatever is important to you first

Thanks dlotters, is this safe and won't trip KNOX? and no way of doing it without reset? I'll have to do a Kies and Helium backup before i start.
Which version of Odin should i use?

SSTIWARI's reply in the following post scared me http://forum.xda-developers.com/gal...ock-rom-via-odin-affect-t3138019#post61992036
His Knox tripped when using a standard BTU ROM from sammobile and flashing via Odin 3.10.6, it sounds risky.
So going back to my original post, would that order of doing seem the safest? Would it even work? Still not sure which app to use to change the CSC.
thanks.

Strange. Everything else I've seen on here and other for UK mobile s suggest that flashing stock roms with Odin is safe and doesn't trip Knox. My own experience confirms that also. But I used the xsa firmware as I've the 925I variant so maybe it's different. Seems odd though. What about other people who have flashed btu firmware? Is his an isolated incident?

After adding my post, i did a little more research, even watched a few videos of the process from beginning to end and i'm a little more confident. Maybe it was an isolated incident, well hoping so.
Going to run more backups and try it tonight.
Did you still have to use the wipe option? if so what was your method or restore?
I've created another post but haven't had any answers yet.

The reason you have to wipe/factory reset is so that your device registers with Samsung for updates against the new CSC. It was previously registered against the old CSC so won't get update notifications for the new one unless you do. At least, that's what I had to do to get XSA updates pushed to my (previously VAU CSC) phone. It's been confirmed by a number of other users over on whirlpool forums (Australian tech forum).
If there's another way to register the device then I don't know what it is
How did I restore? Well, I used Helium to do the back up of app data and sms's etc, so just restored via helium. Discovered Smart Switch backups afterwards but I've never used it myself so can't comment.
OK, no matter what method I try I am unable to achieve a successful flash of my phone. I have tried it via odin with many different firmware versions but all seem to fail almost immediately. The only way to resolve this is to use samsung switch and reset phone to stock. The problem is stock firmware is german vodafone full of vodafone bloatware, I want to get rid of it and flash a UK unbranded firmware but no matter what I do I am unable to achieve this. I can see from the forum that there are many people out there with the same flashing problem but with no real responses on how to achieve the goal. There must be people out there that have achieved this task but don't seem to be offering up much help?
ok

Is your phone international unlocked out of the box? I dont believe it was, because as far as I've read international unlocked phones come with "unbranded" firmware. The unlocked ones I know can be pretty much flashed with "any" international firmware, which is what you are trying to do.
If you dont know for sure. Odin the stock German Vodaphone. Let the phone boot. Boot back to stock recovery, then factory reset and clear cache.
Then let the phone boot...Download phone info app by vndnguyen (free version is fine)...Open the app, go to CSC Code tab. Then that will tell you the active CSC code and your firmware CSC code...you are looking for the line that says Available CSC Codes. If it only lists German Vodaphone (VD2), then I believe you are stuck til the phone is unlocked.
Anyone, jump in here if I'm mistaken. I am using this as reference as, I've checked my G920F. Mine is unlocked tho and I can flash any firmware from any region with no problem. Hopefully I've answered your question.
I had no luck with the firmwares on the firmware page either.
If you are on OI9 check http://forum.xda-developers.com/galaxy-s6/general/guide-android-6-0-marshmallow-beta-how-t3277533
And try flashing the first stock firmware https://drive.google.com/folderview...sharing&tid=0B40ItdHKfkyQd1hJQXVDU3dDU2c#list (not the android M one!) via ODIN.
Basic process is:
Download the above file, extract, there should be 4 files inside (AP,BL,CP,CSC), simply select each one to go in the relevant box on ODIN, then go into download mode on your phone and click start...
N.B. Be aware that the above firmware contains a PIT file which will reformat and resize the partitions on your phone, so make sure you have a copy of the stock firmware that works before trying the flash (i.e. the one which Smart Switch downloads). You can grab it from your windows %TEMP% directory during the smart switch download (it first downloads a file to TMPxxx, then extracts it into a directory of the same name, its these files you want. They should be the four files beginning with the type of ODIN file you are flashing (AP,BL,CP,CSC). The files get deleted after the firmware has flashed so make sure you watch the process. If things go wrong you can re-flash these files via ODIN
As far as I was led to believe and when I purchased the phone it did state factory unlocked. I was able to put in any sim when I received it and didn't have to go through any aftermarket unlock process?
I have the same problem i have a unlocked G-920F with egyptian CSC and firmware 5.1.1 .when i try to flash BTU 5.1.1 via odin, i have the same problem and only way to recover is via smart switch.BTU firmware is from sammobile

its BTU firmware of 5.1.1
and flash this firmware you'll have 4 files AP,BL,CP,CSC,put it in the respective boxes in odin.I have tested this right now and it works
Press "thanks" if i have helped
Well downloaded the app for CSC info and it states available CSC codes are...
ATL, AVF, CNX, CYV, MOB, MTL, OMN, SIM, SWC, TCL, VD2, VDC, VDF, VDH, VDI, VGR, VIP & VOD
Any ideas?
Ok, tried to get stock firmware when samsung smart switch was downloading and installing but couldn't see where the firmware was being downloaded to? Tried windows temp etc but nothing appeared during download and install?

Just type in %TEMP% into you windows explorer address bar and it will take you there. arrange by date modified and you will see the size ticking up during the download, before the flash starts it will extract into a folder with the same name, the md5 files can be grabbed from there
No probs here

Ok, Got it this time, all four files. Will give the method above a go and if it fails at least I've got the stock firmware to fall back on?
Magic, have had great success. Now on the BTU firmware and everything is up and running. Got the stock as well just in case but if this continues to work won't be reinstalling stock. So a big thanks to those who helped

Glad you are sorted
Can any one provide me with a Three (UK) S6 Serial number so that I can download the full official stock firmware via KEIS/Smart Switch? EDIT: I now have one from a display model PM me if you need the firmware
I need to change my unbranded (BTU) phone to The official Three firmware (H3G) (for 4G voice calling)
I bought an S6 from Amazon which came unlocked with AUT region software. I've managed to find and Flash an official BTU firmware via ODIN, however I cannot find a full OI9 H3G stock firmware.
FYI for BTU, the ones from the firmware page do not work for me (even with a PIT), I kept getting the Sw rev check fail device 3 binary 2 error. However a full official flash i.e. with the AP, BL, CP, CSC file did work. Which is why I need the serial number, or alternatively a full copy of the Firmware. I also do not wish to root/flash another recovery as I need KNOX.
Please PM me if you don't want to post on the live forum
Thanks!
I doubt someone would give their serial number, but I would suggest trying a PIT file, it may/may not trigger knox status but I did it to get EE Branded firmware for wifi calling and it worked.
Where did you get the fimware to flash to the BTU?

Already tried a PIT, didn't work... thats why I want the full firmware. I will just go and grab the serial from a display phone at a Three shop, thought XDA might be quicker tho.

As I said in your thread, I got the firmware from this thread... http://forum.xda-developers.com/galaxy-s6/general/guide-android-6-0-marshmallow-beta-how-t3277533 Its a full firmware download rather than the partials that are posted on the firmware page.
looks like @abdussamad tried it out and it solved his flashing problem as well

You have to use a custom PIT file in order for the hidden part to have enough storage so the Three firmware can work.
I have got an unlocked Galaxy S7 (G930F) and have flashed the android nougat update (BTU - UK - 7.0). It is working fine.
Since I have updated to nougat, there are some updates released (bug fixes, I can confirm this on sammobile site) but are not available when I check for the updates in settings.
Any idea on what this issue might be.
If you have either root or custom recovery you can't receive OTAs but you can update using SmartSwitch on your PC

hi mate
Updates ( if you are not rooted) are CSC carrier dependent , if your carrier or CSC do not issue any updates ...you will not have them.
When you checked in sammobile you checked if your carrier / CSC had updates?
No updates on Smart switch

I do not have root or custom recovery. I have downloaded the firmware from sammobile and checked that the knox warranty is not tripped over and the device status is still official.

The BTU firmwares in the UK are not network dependent as far as I know and they come installed in unlocked devices with no network bloatware.
I do remember flashing the CSC (G930FOXA1DPLT - that's the current one) which came with the BTU firmware. The new CSC has updates (G930FOXA1DQB1).
Am I missing something or is the device still dependent on a network to approve this.
Do you get any error?

No, it says "the latest updates have already been installed "
I even had this issue on Android 6 so I downloaded the Android 7 and flashed it via odin. Now there are updates but I would like to get the OTA to update it.

I thought the idea of having an unlocked phone from samsung is to use any sim and get updates directly from Samsung when they release it.

Hi
You get updates either by the carrier or by the CSC , in your case you have an unbranded firmware , BTU, so no carrier updates...you will get an update only when an update for BTU unbranded firmware is release it , independently if there are other firmwares newer than yours around....only way to keep updated to the latests is flashing it yourself any new release , check this thread if you deciede to go that way
Try to get your CSC code by installing Phone Info from the market : I too have flashed the first official Nougat BTU UK 7.0 firmware with Odin, with a complete reset of the phone, but in my case I still have CSC = ITV and not BTU.
This seems to prevent us from getting the new OTA update : somewhere I've read that after the Odin procedure I should have entered recovery and factory reset the phone from there to get the CSV changed to BTU as the installed firmware is a "multi-csc" variant.
We still can download today's new firmware from SamMobile and use home_csc to avoid resetting again the phone.
Hope someone more expert than me can confirm/correct my statements

The BTU has a firmware update available on sammobile but not it's not OTA update on my phone.
What if I download the new update and flash it via odin with HOME_CSC file added. Will it start the updates by carrrier?

My S7 DUOS FD and my wife's S7 F both recieved the Nougat OTA update DQB1 today, mine was originally CSC XSG (UAE) and mi wife's was CSC TTT (Trinidad And Tobago), and both were updated to CSC BTU Nougat Final release, changing the CSC to BTU (this will wipe out your memory in the process but for a newer OS version it is recommended). I had doubts about getting any OTA updates since my S7 is the FD version which does not exists as a BTU phone originally, but in the end I got the update.
Long story short, if you want to recieve OTA updates after sideloading firmware with ODIN with a different CSC, you should fully convert to that new CSC, otherwise you won't get the OTA's.

Hi
if you have a DPLT firmware you should get it soon.....unless your system by some reason is not set as original ( even if knox is tripped but your system is set as original you will get it) anyhow is faster if you download it yourself and flash it , use home_csc so you will not factory reset your phone , NOTE: has to be the same home_csc that you have in your phone right now , not any home_csc for example:
Lets say you want to flash the latest firmware and it happens to be from France and you do not want to loose any of your apps , config or data
1 find out what CSC is installed in your phone ( phoneinfo app is great for that) in your case BTU
2 download the latest possible firmware for your CSC and extract from it the home_csc file , save it , discard the rest
3 download the latest firmware available , in our example France , extract from it download the MAIN-file and extract AP BL & CP save it , discard the other 2 files ( home_csc and CSC from France firmware
4 now take AP BL & CP from the latest firmware ( in our example France) and take the home_csc from a BTU firmware ( why , because is the CSC installed in your phone) and flash the together
In that way you can always have the latest in your phone without waiting for it , phone will not be knox tripped , will be 100%official as is all official firmware
If your using the btu version for UK phones, then how did you manage not to brick your phone? The UK phones do not have snapdragon, they have the Samsung chips.

Thank you, you are a hero :good:. I did update via odin and installed it without losing any data.
As I have said I have previously (about a week ago) used the CSC file rather than HOME_CSC.
I have the Phone Info app, The Orignal CSC code is blank(is it normal?), Does this look normal as I have not checked the CSC before updating to android nougat. I have added a screenshot of it.
For all of you out there who happened to get stuck on 955u firmware containing bootloader 2 installed on the 955u1, there is hope!
I have successfully gotten back to 955u1 firmware and running stock OREO. (and have service again for those who are on non-mainstream carriers {Verizon, Sprint, T-Mobile, AT&T})
You will need (links to be added soon) (My Carrier in BL says XAA and these linked are the XAA firmwares):
USB 2.0 PORT
PRINCECOMSEY ODIN 3.12... link
regular ODIN 3.13.1 (what i used) link
G955U1UES2AQL1_G955U1OYM2AQL1 Firmware link
G955U1UEU2CRB9_G955U1OYM2CRB9 Firmware link
Official Samsung Cable that came with phone (preferably)
Windows OS
A Galaxy S8+ 955u1 Phone (only tried with this)
For some reason flashing just the CRB9 firmware would not work, I had to use the AQL1 and then to the CRB9
Instructions:
1. Extract both firmware files/zips (Put in 2 seperate folders so no mixups)
2. Reboot your phone to download mode (Power off then -- Power + Bixby + Volume Down at same time)
3. Open up princecomsey ODIN and then connect your phone to USB 2.0 Port
4. Add in the AQL1 Files - (BL, AP, CP, CSC) -- (I personally first did the AP, CP, and CSC then had it reboot then i restarted and flashed the BL by itself then rebooted) and press start. (I unchecked everything but reboot and f.reset time)
5. Unplug and Wait for it to turn on to the setup screen, then finish the setup (to verify that it runs and the model number is showing the correct #). If you open up settings it will be all jumbled up and weird, but dont worry. If you dont have service yet - dont worry.
6. Now after the phone is all setup (or if you decided to skip), unplug and power off the phone then boot into download mode again.
7. Now open up Regular odin and reconnect the phone
8. Now put in the CRB9 files (BL, AP, CP, CSC) (I put all in this time and i used the Home_CSC this time but you can use csc normal but no guarantee that would work with getting service again as i didnt try it) and press start and wait til it finishes and reboots (same goes here reboot, f stop time. but also check nand erase all -- to fix storage issue)
9. ENJOY!!!

For all of you out there who happened to get stuck on 955u firmware containing bootloader 2 installed on the 955u1, there is hope!
I have successfully gotten back to 955u1 firmware and running stock OREO. (and have service again for those who are on non-mainstream carriers {Verizon, Sprint, T-Mobile, AT&T})
You will need (links to be added soon) (My Carrier in BL says XAA and these linked are the XAA firmwares):
USB 2.0 PORT
PRINCECOMSEY ODIN 3.12... link
regular ODIN 3.13.1 (what i used) link
G955U1UES2AQL1_G955U1OYM2AQL1 Firmware (link in an hour or 2)
G955U1UEU2CRB9_G955U1OYM2CRB9 Firmware (link in an hour or 2)
Official Samsung Cable that came with phone (preferably)
Windows OS
A Galaxy S8+ 955u1 Phone (only tried with this)
For some reason flashing just the CRB9 firmware would not work, I had to use the AQL1 and then to the CRB9
Instructions:
1. Extract both firmware files/zips (Put in 2 seperate folders so no mixups)
2. Reboot your phone to download mode (Power off then -- Power + Bixby + Volume Down at same time)
3. Open up princecomsey ODIN and then connect your phone to USB 2.0 Port
4. Add in the AQL1 Files - (BL, AP, CP, CSC) -- (I personally first did the AP, CP, and CSC then had it reboot then i restarted and flashed the BL by itself then rebooted) and press start. (I unchecked everything but reboot and f.reset time)
5. Unplug and Wait for it to turn on to the setup screen, then finish the setup. If you open up settings it will be all jumbled up and weird, but dont worry. If you dont have service yet - dont worry.
6. Now after the phone is all setup (or if you decided to skip), unplug and power off the phone then boot into download mode again.
7. Now open up Regular odin and reconnect the phone
8. Now put in the CRB9 files (BL, AP, CP, CSC) (I put all in this time and i used the Home_CSC this time but you can use csc normal but no guarantee that would work with getting service again as i didnt try it) and press start and wait til it finishes and reboots

Im going to be uploading the firmware and yes the VoLTE is working.
Also When flashing the CRB9 after the ALQ1 -- A repartition or nand erase all should be done as when i looked at my storage last night it was only 16GB but since im back to u1 firmware it shouldnt be hard to fix for me. i will edit with main post after i do it to my phone to ensure which one works.

Thank you so much! it worked coming from the g955u on verizon.
Was on Verizon 955U CRC5. Did the AQL1 and didn't have any jumbled or weird settings and storage is fine. Regular Odin failed trying to do CRB9. Downloaded the Software Update/OTA CRB9 update and all is good. On build R16NW.G955U1UEU2CRB9 with March 1 Security patch.
Sorry for bugging, newb here. Will this work on my Sprint Galaxy S8 Plus smg955usqs2bql1? And if so if you could spare a few and and help me. I believe I need this right to get root on my device?

What if you flashed the sm-g955u1 version on to a sprint sm-g955u phone? would there be any way to power that back on, asking for a friend I believe thats what he done. Now his phone will not turn on.

Honestly I do not know all I have is a 955u1 and am unable to test for other models as I don’t have any others, and now since bootloader version 3 is out for the 955u1 it is the end of carrier switching unless there is a workaround found in the near future.
This should still work as long as you keep the device on the same bootloader v2 and not Flash any v3 bootloader Firmware as that will definitely brick the device from what I’ve heard of v3 bootloaders
Sorry for any late replies been really busy lately

I’m guessing your friend must have flashed firmware running bootloader v3 on it
(To tell what BL ver. The firmware contains look at the 5th character from the end and it is should be a number like xxx1xxxx or xxx2xxxx etc...) and if it was a 3 then that would be why as that firmware will brick the phone if it’s flashed on a different model (until there is a workaround)

I haven’t seen any root for 955u/1 models for Oreo yet the only root I’ve seen on the s8 running Oreo is the carrier versions and the international models

I greatly appreciate your response, is it any possible way to fix it? right now it won't power up, not even in bootload mode, nor recovery.
