Do changing CSC to these countries affect signal reception or 5g bands?S23, S23+ and S23 Ultra in UAE are sold International versions SM-S911B, SM-S916B and SM-S918B with XSG CSC - which is for UAE. The CSC of these SM-S91*B devices can be changed* to INS, THL, XXV, ILO, SEK,... to enable internal Call Recording feature.
* via SamFw (free) or SamKey (paid).
No. On my phone everything works fine. And also can be changed unlimited times.
S9080 can use China firmware (CHC) to get call recording, but no Google services.
Ok, I'll take a note!
You can use the samfw tool without resetting the phone. I did change mine from EVR to THL and everything is working. Good luckHey,
I need to change CSC on my S23 ultra to have samsung pay. i need it to use car digital key.
If I use SamFw tool, will I use my data on phone? will it do factory reset?
What do I need to know before doing it?
will INS code be ok for having samsung pay?
Thx for help, been totaly new in this area
yes, it has trojan. I'm on XXV already have call recording. Last week I intended to change to INS to have callerID and spay, but after downloading SamFw Tool, I think I'm still on XXV
Argh already did the update and after the first 3 payments it's now blocked...Do no update to S91*BXXS2AWEA
The firmware is not signed by Google Play Protect - so phone become UNCERTIFIED and Google Pay stops, other SafetyNet dependent also.
At the moment only THL CSC is pushed to ...WEA. Others (at the moment) are on WD1.
TThe is nonoption to downgrade because this is first firmware with new 2 bootloader.
Deleting, Unistalling, Clearing data, even Factory reset do NOT avoid uncertified status.
(There is a chance for updating Play Protect but it's less likely before Samsung new firmware.)
Current option for already updated to WEA:
Just wait for new WEx (after A) or WFx firmware.
for N models, they used to be able to change CSC. I personally did it on my G981N from KTC to KOO to remove Korean bloat. But it was blocked some time in 2021 I think.Ok, I'll take a note!
But I personally do know someone how will switch to CSC for Call Recording on "price" to lose Google Services. So, no reasonable option for "0" model.)
For N model CSC change is forbidden by Samsung. Even all N CSCs has Call Recording, people not interested because of it.
Really?!Thank you. After flashing you mentioned I have to use Samfw tools to change active CSC toThl or xxv. Again please explain how to use the tool to change. I never done this before. I don't want to mess-up my phone currently my phone working perfectly. It's because of native call recorder only Thank you for your time.
Yes , I used samfw for first time in my s23 ultra. The procedure is very easy and safe. I tried INS but then I changed to SEK for the reasons I explained before.
