Flashing UK 7.0 BTU on TNZ branded handset - Samsung Galaxy S7 Questions and Answers

Hey guys,
Been a while since i've done any flashing of ROMs and memory has gone to mush entirely on the subject so have a couple of questions... I'm looking to flash the UK 7.0 BTU rom on my New Zealand carrier branded handset because carriers here suck and take For Ever to push updates.
Basically I'm wanting to know if i'll have any issues like my csc getting messed with, or knox tripping and voiding my warranty and upsetting apps, and do I need to worry about the Modem?
Thanks

I did it the day it came out and no issues. I flashed the BTU rom with the standard CSC and everything works fine. I did not flash the HOME_CSC.
Knox not tripped and working fine for me.

Ok thanks!
So i'm flashing the BL, AP, and CP files yes? Do I need to flash the CSC as well?

Hi
Well , if you use CSC you will factory reset you phone and you will set it to the default csc in the flashed rom..... you could use the home_csc from the latest available stock rom from your carrier in your country ( or whichever cscs your phone has) that way you will not factory reset your phone...BUT as you are using a home_csc from a 6.0.1 into a 7.01 rom there may be some issues ...some carrier specific options may be lost..

Galaxy S6 root > change csc > unroot possible?

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.

What region has the quickest security updates?

you cannot tell or guess which region get firmware update first
but maybe the region that has most user!
:good:
Over at SamMobile Greenman once said that Trinidad and Tobago always is among the first, if not the first. Can't be the region with the most users if my demographic instinct isn't totally off track!
Sorry for the bump, I bought the S7 in Israel, should there be a problem with flashing a foreign ROM?

Hi
No that is not a problem , the only issue you may be concern is your phone CSC ( country code) is not a big deal but some carrier specific options may be not available if you have a different CSC than you carrier

Just see to it that you use the CSC file and NOT the Home_CSC when you are switching CSC. Fill in the BL, AP, CP and the CSC files in the right fields and have the following boxes ticked: Auto-Reboot, Re-Partition, F. Reset Time.
After the flash, power off, reboot and enter Recovery. Select and execute Wipe cache partition and then Wipe Data/Factory Reset. Reboot and then you will receive OTA updates from the new region you flashed when they are released. You should be aware of the fact that your Samsung warranty is void after switching CSC should they notice it. This probably is not likely, but still, be aware of it. Flashing original Samsung firmware do not trigger Knox.
All your data will be lost so back up important stuff.

Thanks for the replies, by CSC do you mean Israel's CSC or the other country's CSC? I'm flashing the newest build from the UK with the November 1 security patch which was build in November, but the Israeli build was built in August and has the August security patch. Could that cause a problem?
Say I filled the UK BL, AP and CP with ISRAEL's CSC (not HOME_CSC), what are the chances for a HARD brick?
Thanks again
EDIT:
If it matters, these are the links for the builds I'm hoping to use:

You MUST use the csc that comes with the firmware package. The csc file contains info on the layout for how the firmware files are going to be organized. You should not mix files from different packages. It is only when you are flashing a newer version of the same region firmware that you can use the Home_CSC file. The Home_CSC file do not contain the instructions for how Odin shall re-partition the system as this is not needed in that case. This is why config and data is not wiped and the phone is not factory reset when using the Home_CSC.
The CSC file must be used when you switch region since the layout in memory is different for different regions.
So you see you will always lose configuration and data and have to do a factory reset upon CSC switching. No way around this I'm afraid!
On the risks of hard brick when mixing files I have no clue. If you are adventurous you could try, otherwise do not try!

The UK firmware you link here is a carrier specific Hutchison 3G firmware and should not be used unless this is your operator. I would suspect that mixing the files is risky.
It seems that there are two versions of Trinidad and Tobago's firmware that you've mentioned in your earlier post, specifically TTT and EON
Are both compatible? Is there another, unbranded firmware that I can get with the November 1 security patch? I'm gonna be using the phone in Israel and my current baseband ends with BPH1

Hi mate
You can use any CSC with any firmware you want ( check the first link i gave you) what i meant about CSC is for example you live in Israel but you have a UK csc , the phone will work fine , but if there is any specific service from you carrier ( Israel ) that depends that you have an Israeli csc i will not work ...because you have a UK csc

I didn't mean that you should flash the Trinidad and Tobago firmware, I just commented on the post saying that the firmware that has the most users was updated first. I think that you should use the firmware that best suits your operator. And if you decide to switch, do not mix files, use all files in the package you flash, and do not use Home_CSC.

It worked, but the H3G ROM is heavily bloated
Is there a way to restore the original Samsung boot animation? Also, how do I make it mount the system read/write?

What you want is not possible without root access. You need to go to other parts of this forum to do research on how to root your phone and install custom roms.

Already rooted of course, however even with su enabled I can't write to /system
I also tried to switch the boot animation with substratom and it didn't work, are there other apps/ways that are known to work? I just want the stock Samsung logo back (or anything that doesn't have a site address on it lol). I'm not eager to give root access to everything that claims to be able to change your boot anim, and Google brought up nothing
EDIT:
I've managed to get rid of the H3G boot and shutdown animations by going to /system/media/ and removing *.qmg, then going to /system/media/video/shutdown/ and removing shutdown.qmg
Do this at your own risk, it won't restore the original Marshmallow animation but it will PROBABLY make your device stay on the "powered by Android" logo instead of going to the carrier boot animation

I'm tired of waiting for my Network to release the firmware...

That answered some of my questions, thanks.
Please see screenshot for my mutiCSC firmware. I am running Android 7 but haven't changed CSC since I got the phone in December 2016. I got it with Marshmallow on it. Everytime I upgrade firmware with Odin I select Home CSC so my CSC never changes.
Since the solution is in the CSC (afaik), which CSC do you recommend I flash with Odin? I understand how to flash with Odin if CSC not in my multiCSC firmware (tick re-partition, etc...)
My home network is Vodafone (CSC is XVF which is not part of my CSC).

If i got it right you are not root, right? if you are root there are other ways....
Yes you need the right CSC to make it work , in this case Vodafone XFV.
When you change to a different CSC is recommended to check re partition to adjust to the possible change in partitions
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930F/XFV/download/G930FXXU1DQD2/131635/
Download the firmware and extract the correct CSC from it , if you do not want all the vodafone stuff you could download and unbranded firmware and use the BL ,CP , AP from it and the CSC (XFV) from Vodafone and flash it all together
BACK UP FIRST .......

Yes, no root (for now). Will only root in a year when I get my upgrade on my contract.
Thanks, you basically confirmed what I suspected. Just needed a Jedi to point that out so I have peace of mind. I shall report back... :highfive: :good:

No problem mate.
Let us know how it goes

Note 20 ultra d/S firmware

I don't find note 20 ultra Dual sim firmware. Does the N986b/ds use same firmware as the N986b without loosing dual sim function? Reason I'm thinking on flashing is cause I have a xfa version and network reception is really bad and thinking on flashing btu. Do u guys think that a new firmware might help? (all other devices I get 3 bar at home and with note 20 ultra sometimes I have no network)
Check here for your required FW.
N986B is the Global Exynos model (it is Dual-SIM = DS); in case if any regions are single-SIM for this particular model (I'm not aware as such), the N986B FW will still be the same as for DS.

It's possible I think.
But..... only try other Exynos region FW (cannot flash FW for SnapDragon variants on N986B without running into problems).
Check on Note 20 threads regarding properly changing CSC.
Also, there are some .xml modification solutions that enable you to activate extra 4g/5g bands - worth a search & try.
(Sorry I don't have the links to hand, but recall seeing these discussions before on N20 XDA forums).
I'm with Three UK does this help

If I download BTU firmware and just flash it with Odin won't it just install firmware and radio software? Sorry I been away from Samsung for some years now. In past was just easy to flash a d all would work.

When you un-compress the firmware download you will get five files. Each go into a specific part of ODIN - can't mistake it - but if you want to keep data intact you will need to flash Home_CSC. This will NOT change your regional CSC however.
You also need the "hacked" version of ODIN found on this forum easily.

If I flash that 5 files will I still be able to get Ota?
When I flash should I use CSC or HOME CSC. So that I keep getting updates? I think that if I flash UK international firmware, will sort alot of my issues. It feels in my country software is never very stable.
Flashing CSC will delete your Data but flashing HOME_CSC will not delete your Data.

Will both ways I still get Ota even if I install btu firmware? (is there any benefit on me flashing the csc and not Home_CSC?)
Once bootloader unlocked I don't think you can get OTA - You'll need to flash FW updates manually.
Flash CSC for clean install.
Flash HOME_CSC if just updating FW & need to preserve user data.

So if I flash a different rom I won't be able to do Ota anymore?
No

Not unless you re-lock BL.
Hopefully they'll come with a solution. I would like to flash a different rom (different country) and still get Ota updates as normal. I don't wanna be flashing every month
These are stock roms, why do you need to unlock your bootloader?

Yes I understand but why is someone talking about unlocking your bootloader?
You just want to change your CSC...

I end up selling my note 20 ultra. Signal was bad. I'm using my p30 pro for now until I get something else. But I doubt will be a Samsung.
Thanks for help guys

Question One UI 5 is out. Flashing INU on EUX phone. What about OTA updates ?

Hello, I've been waiting a really long time for One UI 5 and I couldn't wait anymore once I heard the stable is out in India. I downloaded the INU firmware using Frija then I changed my CSC to INU using SamFwRP tool and flashed the INU firmware using patched Odin. Then I reverted back my CSC to EUX again with SamFwRP.
After all of this, finally did a wipe cache and factory reset. Now I'm wondering...since my CSC is back to EUX...will I still receive OTAs ? For example One UI 5.1 OTA or December security patch whenever that releases
EDIT: Weirdest thing is when I flashed INU HOME_CSC on my phone there was no data that was reset. Is it because they're both OXM ?
EDIT2: DISCLAIMER - I'm not an Android dev, I'm not knowledgeable on anything technical or otherwise. Please take advice from anyone else but me!
Thanks for the tip about Frija, I had forgotten all about that one (been checking sammobile and galaxyfirmware daily for weeks now) I'm downloading now and will edit this post with success or failure! (I'm EUY)
As for your question about still receiving OTAs or not, I honestly don't know because I've rooted every phone I've ever had in 17 years! but I can't see why it would be a problem if you didn't receive them as you can always download them from Frija surly not?
Okay download complete, I'm going in.. wish me luck!

Well yeah, you can. But I don't wanna lol. I'm not a ROM hax0r. I'm just a power user. I don't even have a Windows laptop around most of the time and Heimdall looks scary .
Is EUY the same as EUX ? I saw it on the firmware websites...but I never heard about it. Is it for France or something ? Rest of the EU uses EUX as far as I know.
I think EUX, EUY, INU are just the same ****, not sure. They all have OXM Multi CSC and they kinda look identical tbh as far as numbers go. So if you revert your CSC back to EUY...updates should work, no ?
Success!
I just flashed the Magisk patched AP file the CP file and HOME CSC file and all up and running Android 13/One UI 5... (also rooted) thanks bro..
I think if you revert your CSC back to EUY then yes I can't see any reason why you shouldn't receive OTAs
thought it was too good to be true, keep getting a service provider update required (but it won't update) and access denied here and there. can't even odin flash back to Android 12 for some strange reason hmm
It's working perfectly for me. Have you reverted CSC ? And deleted cache and factory reset after flashing. I have literally 0 errors and 5G works. But I deleted did a wipe cache and factory reset and reverted CSC as well

What Odin version too ? I used the latest PatcheD version from here: https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/
XME - Malaysia released OneUI 5 Android 13 for Z Flip 3
This is how my INU firmware with EUX CSC looks.

I think it's to do with trying to root it. It detects root and denies access to the PC, to update the service provider and many more things something like 'we have detected a tampered device, please contact your customer service'

All okay now must have been gremlins .. I think it detects your CSC when installing, it reads your simcard.
Thanks for this thread!
It worked very well for me. Factory reset is a chore after, but everything works and I haven't had any issues so far. I do not root, so nothing to report about that.
Installed the firmware on my BTU phone
Works wonder 0 errors or issues
did Samsung and google cloud backups before flashing during setup restored both and its as if I never did a thing everything was put in its place and it was the most effortless phone setup I ever did
Now I'm just enjoying my android 13

Hi, flashing the home-csc does not restore the phone to factory settings ( wipe data etc ) If you flash the csc, then your phone will be wiped and restored as it was out of the box. Also you dont have to change CSC, i'm on XSA and I flashed the IDU firmware.... This does not chage the CSC of the phone anyway. A lot of the Samsung firmware are multi - CSC these days.

I'm not sure you actually have to do it. I'm just a big giant noob with no knowledge in Android, this is why I did all that

So I could actually just have stayed on EUX without changing my CSC while flashing and everything would have worked fine ? Thanks, that's really good to know!
