Is it safe to flash A505F firmware on the A505FN device? As far as I know, the only difference is NFC.
And is it possible to void the warranty by doing this?
I tried Smart Switch a few times, but no updates.

Hi thanks for your reply.
Should I need to remove all accounts, and make a factory reset first?
Smart Switch only will provide you the newest firmware in the same line, not an option to use other different firmware from a different region.
Ever is recommended to do a factory reset/format data before to "switch" to other firmware and make a backup before to restore it in just minutes with SS.
Install Phone Info(Samsung) and there you will find the CSC availables for your device before to change the firmware (most of the international models are multi_CSC compatible), search for the regions and compare them here https://www.****************/2017/0...specific-product-code-csc-and-country-region/ if some of them is convenient for you then you can flash it, check before your bootloader version, I think all are now in v1 but check it before to go further.

Yes, you usually can (I switched a lot of times) but you could find some issues regarding to radio/baseband depending on how different they´re.
Take a backup before using Smart Switch, take note of your actual firmware in a safe place if something goes wrong and don´t forget to enable USB debugging and OEM unlock before to go.

Hi,
Good yes already did a backup and OEM Unlock and USB Debugging are one.
I'm simply waiting the firmware to be downloaded. Take very long time to download from samfrew
Finally succeeded in flashing to INS.
I forgotten to remove my Sim Card but even that it has changed the CSC.
Thanks a lot for your help @SubwayChamp

Hey, what's the model of your device? Is it FN, or F? Because Indian firmware is A505F, so I don't know if I can flash A505F firmware on my FN device.

My model is A505F. I don't think you may install F on FN. It may work but you may have several problem with correct functionality of the phone or even brick it.

F firmware on an FN device should be ok afaik, but I believe you'll loose NFC
Also keep in mind that INS csc has this string in cscfeature_network.xml
<CscFeature_Message_ConfigImeiTracker>+919560345888,+918424098931,+919176905802</CscFeature_Message_ConfigImeiTracker>
I remember that this was a problem on custom roms for the old A-series since all roms for some reason added INS csc, so a bunch of users in europe got charged extra for messages to india if they didn't remove that from cscfeatures..
Not sure if it still acts the same, but I can confirm that the string is there in INS csc for A50.

Thank you.
There is finally firmware with July patch for FN versions of this device, so probably I'll wait few days, because only 5 countries in Europe got an update to the newest version, skipping June security patch, but I hope we'll have new features in the camera.

Change CSC on N975W

Does anyone know how to correctly change CSC on the Canadian N975W? I purchased a used Note 10+ that the previous user bought from Samsung direct but had a Bell sim so the CSC shows BMC and has bell bloatware. I'm trying to change it to KDO but no luck with any firmwares yet. Any ideas or steps I'm missing?
Tried both KDO and XAC firmware but the file names seem that they're the exact same from both updato and SamFirm.
Using patched odin and everything loads fine - using CSC not the Home CSC.

it should change depending on sim inserted as long as it contains the csc on the device.
you can use phone info or similar to see available csc.
you can also try *#272*IMEI#
Domt think itll help but i believe you could also install U and U1 firmwares to ur W variant. Maybe trying the U1 will help

Go to http://www.samkey.org/ to buy SamKey CodeReader – 15 points is $ 45 USD, and there are split sales on some trading platforms for about 3 points $ 6.6 This is what you want to do
Download the SamKey program on its website, and download the driver together if necessary

If its hong kong variant then it should have TGY csc
Moreover, you can change csc with samkey(no root required). Buy from ebay

May be after rooting, it can be done but it may corrupt imei as only few users reported this.
Samkey method is very easy. Before buying, contact them and provide all details of your phone to check whether it support your phone or not.

No you are wrong. TGY or BRI are basically same.. Only network connectivity change like 5g, volte, wifi calling support. Don't know about chc but you can change it to tgy or bri.
I read your posts in another csc thread. You should be on default theme. Then install apk. It will show in themes. Then u can change csc

Change CSC/different region note 10+

Hello, I currently have an SM-N976N.
I bought refurbished and live in Ireland.
I am looking for a compatible firmware that's not Korean but not having much luck. I can't flash anything in Odin except n976n firmware, and even that didn't seem to get rid of the sky telecom provider bloatware and branding.
I can provide CSC etc if anyone thinks they can help! Looking for something like a global or UK Ireland Unlocked like the B...
tried to flag KOO firmware...I used CSC as opposed to home Csc but I also used userdata file in Odin as well.
The sk splash screen and bloatware is still present.. There was a warning or info message on phone after I flashed, and then it rebooted again. I couldn't read it as it was in Korean.
Also, if there's no way to change to a euro firmware, is there any way to change bootloader/recovery/download language?

Hello, try this firmware, you can convert your N976N to N976B, none of the files are tested by me, let me know if you had any luck successfully flashing your phone.

Question Korean Z Fold 4 Firmware Change

Hello. I just got a Korean Z Fold 4 and now I was wondering if I could safely change the firmware to the Indian firmware. Any guidance for the same would be highly appreciated. Thanks.
Model Number- SM-F936N
What are the benefits of doing this?
The only reason why I wanted to do it because I could not use certain apps and certain pre-loaded SKT mobile apps were installed which I could not delete.

Have you tried changing your csc to KOO which is unbranded using the samfw tool? https://samfw.com/blog/samfw-frp-tool-1-0-remove-samsung-frp-one-click
Not sure if you can try and change it to an Indian CSC of your choice. But you can try changing your csc first to KOO first which will remove those bloat and restrictions a carrier csc has.
