Hello all, new here! Never rooted a device, I'm very technical and confident but would like to ask the question as to why I'm looking to root or change CSC.

Currently my S22 ultra 512 is a Dual sim Hong Kong purchased device. TGY is the current CSC, basically I'd like to use the esim option and phones sold in Asia specifically China, Hong Kong & Macau at least I'm told have this disabled. My note20 ultra dual sim is the same. By changing csc/firmware can I enable this feature that other s22s have? Basically is there another s22 with identical hardware dual SIM and all that I can put on the phone that will enable this feature? I'd like call recordeding if possible as a phone feature rather app but it's not important. I'll attach screen shots of what versions I currently have. Sorry if I'm asking the wrong questions I'm technical but new to android rooting.. Willing to PayPal or donate to anyone who can assist me through the process. SM-S9080 TGY I know the Taiwan sold device is basically the same hardware but have not received a clear answer if esim is enabled, thinking no but figured I'd mention it. I'd also like to do the same to my Note20 Ultra. Thanks in advance 🙏

I think SM-S908E/DS is the same hardware



Dual sim snapdragon variant for midd&le east
Would there be any issues using a UAE CSC such as XSG? Or would another CSC be suggested? I'm aware that in parts of UAE you can not use WhatsApp or equivalent calling ect? Sorry for the basic questions, last one lol.. Doing this will root the phone or just change the software?

Thank you kindly

Egy csc have call recording , but this is only valid for s22 ultra because both are snapdragon , for note 20 ultra different hardware

I'm having exactly the same issue... just tried out the HK and CN variant. Both don't an eSIM support.

However, I've also read somewhere that Samsung has "dropped" the eSim support in on of the recent Firmware versions, because the had too much trouble with that.

So the quesetion is: Is this a regional issue (e.g. TGY, etc.) or is is a "Version" issue (e.g. an earlier version still might have it)

Best!

i want to share my experience with my note9, it was the N variant - South Korea, i had network issues in which case i had to root my phone and install a custom rom which had csc of my country and i worked great.

if you could do with a rooted phone follow this:
1. check if your phone is listed as rootable.
2. check if your phone has a custom rom:
if YES you could see or ask for what you need ( in the Rom's forum or the developer).
if NO wait and keep researching.

dont flash another region firmware even if its the "same phone" you might break the phone.

Okay, quick info: I've flashed all three regions (China, Hong Kong, Taiwan) on the SM-S9080 (current firmware versions june to Sep) and none of them have eSIM support.

This is really annoying - especially when all the offical samsung websites praise that the phone supports esim.

I'm personally pretty pissed off and the key reason is that I know that other users of the same phone in other regions of the world can use it and I'm not able to do this, because the programmers just want to make their lives easy and "silently" drop this feature from the firmware.

Something similar happened about 15 years back with a Sony device and since then I've never ever bought anything from Sony again (neither phone nor anything else). So the same is probably going to happen with Samsung.

When you flash a different CSC, I read that since basically the firmware reads your sim, grabs the CSC from that, that if you leave it out, on the boot up screen before you start the setup, you can hold Volume down, I believe or some button combo to skip through set up so you don't need a SIM to complete it.. then you have the actual firmwares original CSC and not the one that was read from your SIM card.. Cuz if not no matter what firm u are you flashing, if your SIM card is in there and you run set up it's going to go by that. The firms are supposedly all the same but what's changes is the CSC each time.. now overseas, United States, snapdragon vs Exyno it's a different story. They do have different firmware's...
But I do know that the phones are basically all universally the same all the same hardware but it's the firmware the software that does all the matter of difference... Including the bootloader for instance. We all have the same hardware but I can't unlock mine it's software there that can do it.. if I find the site up forward it for you.. have you gone into the service mode after enabling it? There's a bunch of crap you can do in there that has to do with antennas and SIM cards and ESIM stuff you might just need to enable something.

What I've (think to have) learned so far:
  • There are two different hardware combinations: (a) the snapdragon variant and (b) the Exynos combination. For each combination, there are differernt firmwares available
  • Each firmware (e.g. SN-S9080) is a special combination of modem-settings, software configuration, etc. that is geared to optimize the phone performance and battery consumption
  • For each firmware, you have then certain CSC variants, wihch then further add which apps are available, etc. (for example in the Taiwan variant, Google is available, while in the China Mainlaind variant it is not)
  • During the first-time installation process, you can choose the language of the phone (and maybe also the CSC), but you can't change the firmware

Therefore, my problem is this: I've tried all the CSCs which are available for m firmware (SN-S9080) but none has eSIM support. Now I want to flash a differetn firmware (e.g the SM-S908E firnware), but Odin currently doesn't let me flash this onto my phone.

Does anyone have a guidline of how to flash a SN90E firmware onto a phone which currently runs a SN-S9080 firmware?

Best!

i think the chinese s9080 is locked down only because you cant flash other firmware like other models most secret codes like to change bands dont work and this model took agesto get one ui 5.0 update

Well, I can flash different CSC variants, e.g. the Taiwan or the HK variant (and these are not multi-CSC firmwares, but seperate files).

However, does anyone have an idea of how to flash e.g. the S908E firmware onto a phone that is currently running S9080?

I was able to flash all files of the S9080 variant (including BL - the boot loader), so that means that the phone is *not* locked, right?

I've tried to click the repartitioning option (because the S908E is bigger than the S9080), but that also didn't help.

Do I maybe really need need to "root" the phone first for flashing another firmware? This doesn't sound logicall, so I tried to avoid rooting so far ...

Any ideas or a link to a "how to" is warmly welcome ...

with an without SIM card didn't make a dfference. The firmware files for 9080 are all single CSCs anyway.
