Hi guys and girls of XDA!
I have recently bought a used A5 2017 Dual SIM on eBay and I am in awe with its battery life even after the Oreo upgrade.
However, Samsung does not sell Dual SIM models here in Germany, my model comes from Iran (CSC: THR)
I have read the forum, but I haven't found answers to my questions.
I want to flash a DBT version onto my phone ans I have a couple of questions.
1) I have a DS model which were never available on a German market. Will Dual SIM work after I flash and will I get updates after I flash?
2) The german version of (mono-SIM) firmware, which is available on Sammobile still has A520FXXU7CRH9 baseband. I have already updated to the -I9 one. Does that mean that I cannot revert back o the H9 and will have to wait until german phones get I9?
3) My phone came with a sticker "Middle Eastern and African SIM only". Both slots work with German (and some other) SIMs as of now. Will this setting revert back and it will be locked to those SIMs, if I change CSC?
4) If I will apply the Combination CSC from Sammobile , will I get access to every region-locked option without tripping knox?
Thanks in advance!
Alex.
Anybody here? up!
I don't know the answers to your specific questions - but if the dual sim (Iran) phone you have works with your german sims why are you trying to reflash it?
Is there a problem or something that is not working?
I live in New Zealand and have an imported UAE (United Arab Emirates) 2017 A5 with dual SIM and it works just fine. I havent tried the second sim, but have heard of other people that have and it works as expected. The phone doesnt have any UAE junkware. You are right - the battery life on this phone is great. I did find the always on display uses more battery that I like though. Really wish they had an option that just turned the AOD on when you got a notification (new email/text/missed call etc) but Samsung don't seem to want to provide useful features like this. I came from a galaxy Note 2 and miss that little notification LED
If it helps, I see that the A520F and A520F/DS do not have different firmware - I have searched and there are plenty of posts on this forum where people have flashed Dual SIM hardware with the 'standard' A520F software and report that the dual SIM functionality works fine.
https://forum.xda-developers.com/samsung-a-series-2017/help/sm-a520f-to-sm-a520f-ds-t3704566
The DS model was never officially sold in new Zealand (the single SIM model was) but I have received the Oreo update and several security updates for my phone anyway since I bought it.
Hi, thanks for your reply!

I get 26-28 hours of norml usage.
However one thing that irritates me is why it loses up to 10% over the night? Everything is closed and AOD is off, too. Other than that I had to uninstall Chrome because it literally ate up trice as much battery as everything else added up, including screen.
Not sure about your overnight power loss - sounds a litle high...
I use my phone very little and usually only charge it every 4 or 5 days.
AOD uses more power than I like (I have seen 1% an hour mentioned and that is probably about right), so I switched that off.
Really annoyed that Samsung havent made an AOD setting that only enables the AOD on when there are notifications (Missed call, new messages). I would really find that useful.
Have searched all over but cant find any apps that will do this.
For those interested, here is what happened.
1) I have a DS model which were never available on a German market. Will Dual SIM work after I flash and will I get updates after I flash?
Basically, it is the same model and the same firmware. The "normal" firmware for a non-Dual-SIM market works perfectly with a DS model and gets updates via OTA.
2) The german version of (mono-SIM) firmware, which is available on Sammobile still has A520FXXU7CRH9 baseband. I have already updated to the -I9 one. Does that mean that I cannot revert back o the H9 and will have to wait until german phones get I9?
The main thing is that ninth digit ("7") because it represents the revision of the firmware. As long as it is the same, you can flash it. If not you will get a brick.
3) My phone came with a sticker "Middle Eastern and African SIM only". Both slots work with German (and some other) SIMs as of now. Will this setting revert back and it will be locked to those SIMs, if I change CSC?
It didn`t happen to me.
4) If I will apply the Combination CSC from Sammobile , will I get access to every region-locked option without tripping knox?
I did as follows.
I flashed the DBT firmware from SamMobile and got myself a british code because it is a standard one in this Multi-CSC.
Knox not tripped. But VoLTE and VoWiFi still not working
Then I found the Combination ROM (FACTORY BINARY) with the same revision as the firmware (See question 2 about the "7").
I flashed it, dialed some USSD code. Then menu appeared from which I could choose the product code.
I chose DBT, wiped the data and cache and voila, I had a DBT phone with working VoLTE and VoWiFi otb.
Knox not tripped 0x0 !

Hello Experts,
I have a Samsung Galaxy S20+ 5G purchased in Canada and not associated with any service provider. I am planning to use it in India and I have 2 SIM's in India. Samsung Canada Firmware does not have eSIM feature and there is no SIM Card Manager function in settings. Can I flash any other region firmware and have the eSIM feature enabled ?
The question should b e, does the snapdragon variant support e-sim, cos am stuck with a S20 +5g purchased in usa but no e-sim
Galaxy devices in India are typically Exynos variants which offer eSIM functionality. Flashing different firmware on a Galaxy S Series Snapdragon variant won't enable eSIM. None of Galaxy's Snapdragon variants except The Fold are eSIM capable.

It does, bit esim is disabled in Canada, by soft. Instal U1(xaa) instead of W soft, esim will be enabled.
Have u tried installing a Esim? Is it working fully?

all s20+ 5g should support esim. (esim is inegrated to a snapdragon chip) BUT some of them are dissabled by software. but such a models like 986U or 986V, for example, were lock by operator and you could not install a software from U1, that includes esim support. i might be wrong. i installed U1 soft to a 986W model (that was without esim support. Now, esim works perfect. s20+ updates online. samsung pay works correct, knox works as well)

I have Lost 2nd Physical sim option after update to OneUI 5.1, on my 988B, before the update i was using both physical sims ok. Now only 1 physical sim and 1 eSim option is there. Please help
I am trying to flash a U1 firmware. I keep getting Fail (Auth) on Odin. I'm using a patched ver 3.14.1 of Odin.
I've selected USB debugging on my phone. What am I missing?
Can anyone help?
I have a note10+ t-mobile carrier. I bought it in china and still living here. It works fine, but on android 9, one UI 1.5 SM-N975U, the phone keeps asking me for an update which I did once and blocked my sim card after, so I had to return it. They back for me android 9 . my question is if I want to flash my phone to another carrier, it should also be t-mobile or USA, and can I do it with an open carrier, which I can use with any sim card?
and before flashing, what the most important things, I have to be careful when it comes to firmware or the phone model?
if someone can share with me the link of firmware I can use with the newest android I can install that would be awesome
my CSC is: N975USQS2ASJ8

Hi all,
I purchased an A52s 5G (SM-A528B/DS, snapdragon version) last week. I never had a Samsung before so I’m learning now about CSC and such.
I noticed that I don’t have the call recording function even though my country should support it (ILO). As it turns out the device has XSG CSC (I guess it’s a non-official parallel import).
I gathered information around the forums and I’m trying to understand if I can change the CSC by factory reseting and doing the device setup while my ILO SIM card is installed.
Apologies if my questions are stupid and the answer is obvious, but I couldn’t piece it together.
I’m trying to avoid tripping Knox to retain my warranty.
I read somewhere that ILO and XSG are part of the same multi-CSC group (OJM) and that it should work?
I read somewhere else that it no longer works on One UI 3.1/Android 11 versions?
I read somewhere else again that samkey may be a viable solution?
So should I try just by factory resetting the phone? Or try samkey? Or?
Is there any way to change CSC on the fly and avoid having to factory reset the device?
Thanks so much in advance,
Tal
I used to require a SIM to change the CSC but was able to do without it this time.
Doesn't trip Knox. There's a list of countries that details which have call recording built in.

To anyone who might encounter this in the future, My phone was bought trough GoMobile a parallel importer in Israel who didn't have call recordings available although the official one had.
I used SAMKEY in order to change the CSC into "ILO" the Israeli CSC and it worked getting me back the recordings and even had gotten OTA's after it.
I bought an A52s 5G on Amazon UK, and the model that arrived was a Romanian one. I find two things very odd: there is nothing outside the box to indicate that the device is not a UK one (product code would suffice), and when opening the box (which was untampered, as expected) it had a UK plug charger, adding to the fact that the device was destined for the UK market. The back of the device shows a sign for compliance with UK CA standards, and booting it first time, it greeted me in English. However, soon after I figured out the shortcomings and I found that CSC is set to ROM. Factory resetting the phone with a UK sim didn't make much difference however this time the phone greeted me in Romanian. While I've resolved the issue with.. the usual method, I find it dodgy and either the seller went to great lengths to hide the originating country or Samsung is creating these devices targetting Romania but actually making them look British, for.. reasons? Both possibilities are weird.

did you succeed? do you have call recording?
For some reason I've never been able to buy a Samsung that used a single sku CSC.
Even with ICCID locked devices they always shipped with the multi-csc/multi-csc2, so I've always been able to use a SIM Card to change out carriers unless the EFS/CSC partitions blocked it partially.
And even in those couple cases, I've always been able to cross-flash carrier firmware for that device to switch networks when need be.
This method even allowed me to use my AT&T locked Galaxy Note5 with T-Mobile Firmware. The only bug was the AT&T Modem's lack of hardware support for all of the TMO network bands.
Other than that. I even bested the Geek Squad at Best Buy...
This method worked on my A32x 5G.
As the title suggests, I was able to successfully change the CSC on my factory unlocked (unbranded) Fold 3 - F926B/DS bought in Germany with OXM firmware having Android 13 & one UI 5.0 from EUX to INU csc using SamFW Tool v3.31 in hardly 2-3 mins. Kindly note that I also looked into other options to do this like Samkey tool (paid service) and alliance shield app (which doesn't work anymore) etc before engaging with the SamFW Tool as none were simple/working with no complications whatsoever involved.
My main objective to change the CSC was to enable call recording and couple of other features (including some pleasant surprises listed in the end of the post) which were available in the INU csc with little to no hassle. The process was pretty simple, straight forward and most importantly, FREE . It DOESN'T require any factory reset, flashing of roms or wiping cache partition before or after the process.
The step by step guide process which worked for me is as follows:
STEP 1: Click here - SamFW Tool Download - to download the latest version of SamFW tool.
STEP 2: Remove the sim card and connect your phone to a computer and make sure the phone's drivers are installed.
STEP 3: Unzip the downloaded file. Right click on the file SamFwFRPTool.exe and 'Run as Administrator'.
STEP 4: After the software opens, make sure your phone is detected before proceeding. If its detected, click on ADB tab in the software.
STEP 5: In your phone, go to developer options and enable 'usb debugging'.
STEP 6: In your phone, open phone dialer and type *#0*# to get into test mode. Leave the phone unlocked and keep it aside now.
STEP 7: Click on 'Change CSC' button in the ADB tab of the tool. Now the tool will connect to your phone, check and list the available CSCs which your phone model supports as shown in the pic attached.
STEP 8: Choose a CSC which you wish to change to from the drop down menu in the pop-up window as shown in the pic attached.
NOTE: The tool also has the option to force the phone to accept a CSC not listed/supported as well by manually entering the same. However, I would not recommend doing it if you really wish to get OTA updates and also to evade any unforeseen issues. I must admit, I haven't frankly tried this and do not know what lies in the pandora box to be honest.
STEP 9: After choosing the CSC from the drop down, the tool quickly connects to the phone, changes the CSC and restarts the phone.
STEP 10: After the phone restarts, unlock the phone using your pin/password, insert your simcard, check the change of CSC in software information, disconnect the phone from the computer and also disable the 'usb debugging' in the developer options.
That's it! All done. Phone restarts with the new chosen CSC and the related features will now be active!
BONUS: There is also an option in the ADB tab in the SamFW Tool named 'Battery information' which gives the complete information of the battery status including the 'charge/discharge cycles' along with its temperature, voltage etc. like in the pic attached. Do note that the information shown in the 'Genuine battery' section isn't correct for some reason and always shows as 'NO' for any phone with/without genuine battery.
With my choice of INU csc the following major changes/surprises were noticed over the EUX:
1. Call recording and a couple of other INU specific features are now enabled (google for more info on what csc enables what features).
2. Not sure why but Battery backup has increased significantly after the csc change to INU. SOT (Screen On Time) which has fallen to 3-4 hrs after the OTA update to One Ui 5.0 & Android 13 is now back to 5-7hrs or more.
3. RAM management has definitely got better. With EUX csc it used be around 5-6GB during standby and now its always around 3-4GB when the phone is idle.
4. Instead of 4G or 4G+, now it shows LTE and LTE+.
5. Mobile data speed has increased both in 5G (Jio True5G network) and in LTE+ when compared to EUX CSC.
6. 5G signal strength has improved drastically. Signal loss or switching to 4G+/LTE+ is very low now.
7. 5G to 4G/LTE switching while calls (VoLTE/VoNR) is more seamless now. Latching back onto 5G network after a call is a breeze now unlike earlier with EUX csc.
8. Phone definitely got faster for some reason. Can very much feel the difference when switching between apps, multi-tasking, even opening/closing apps and other day-to-day tasks.
etc...
Haven't tested whether the OTA updates will still get pushed after the change in CSC yet, as my phone is already updated to the latest patch as I write this. Should absolutely work IMO as long as we choose a CSC which the phone supports but in any case will update the thread once the next update via OTA is available/pushed by Samsung.
Disclaimer: Please be informed that all the above information is purely based on experience of using the tool for changing CSC only which worked well for me with my Fold 3. Cannot take responsibility if it doesn't work for you.
Does it work for Fold 4. Want to change CSC from Korean Region to INU (India). Please guide
Sorry, haven't tried it on Fold 4. Logically it shud work, I guess. There is no harm in connecting n checking what CSCs does ur model supports using the tool IMO.
Tried out but it does not work. It shows only the Korean csc. Even that seems to be not changing
Oh k. I think the tool works, else u wudnt b seeing the CSC which ur phone supports.
I have checked sources in the web as well on this and looks like Fold 3 or 4 with Korean CSC supports only CSC from Korea.
I guess u can still force a CSC on to it replacing the Korean one but thats too risky as u will b missing OTA updates and im not aure wat all things it will mess up.
Awesome! It works and it doesn't wipe the device. I just switched from G975U VZW to CCT without any issues.

Happy to hear that. BTW I also got samsung pay/wallet to work as well by installing its apk file today after changing the system language to a local one specific to the changed CSC i.e., English (India) for INU CSC in my case.
I confirm that it is working on a stock android 13! Great tool!
(It worked on the second try though )
Has anyone tired it on a Fold 4, Mine is XAA and I want to convert it to INU. Haven't been abe to do it as yet.
Let me know if someone finds a way, mine is a US version and I want to convert it to the India CSU.
Thanks in advance

Oh great. Getting otas after the change?
Does OTA work after change?
Hello, can somebody please briefly summerise the options for switching the CSC/Firmware?
I read other threads and this one and now am confused which method actually would work for me.
My situation: i have a Samsung A52s 5G purchased from Deutsche Telekom in Germany, sold separately, not bundled with a contract.
And i am having a contract with a different carrier on a different network, but a german SIM card.
My phone is configured all english, and i need to keep that.
Because of assumed network optimisations and the problem of delayed updates of "branded" phones, i would like to convert the phone from the current CSC of DTM to the DBT using fimrware (A528BXXS1DVL2/A528BOXM1DVK5/A528BXXU1DVK5/A528BXXS1DVL2), which i hope would link me to updates directly provided by Samsung.
I found "https://forum.xda-developers.com/t/...official-firmware-all-samsung-device.2697238/" and "https://forum.xda-developers.com/t/...-multi-csc-codes.4436853/page-5#post-87485577 ", but i am not sure whther the methods described there only apply for UPDATING (within the same CSC) the phone with non-OTA methods, or whether that also covers SWITCHING the CSC?
In the end i have two questions:
1) So far i believed that "simply" putting an official stock Samsung firmware (multi CSC in my case, containing the DBT, but apparently NOT containing the DTM) would bring me there.
But then i read that this might not be suffficient. Instead i also would have to switch the CSC in my Phone's config, which apparently would require purchasing a license for a Samkey unlock code.
Because otherwise i would not receive any OTA updates once i switched just the firmware.
Is that actually true?
I would prefer not to have to buy a Samkey...
And to make the confusion even bigger: now i read, SamFw Tool would also be an option?
But: is that trustworthy? And: from posts of some of you: this might even obsolete to switch the firmware, do i understand that right?
2) If switching firmware still is required: would using Odin/Heimdall be the only option to switch the firmware, or would adb sideloading do the same job as well? I am asking because i don't have access to a windows machine.
Would be so great if someone of you could untangle my confusion a bit, thank you.

Did not automatically receive the OTA updates with the recent DVL9 update. However, tried a work around to change the CSC back to EUX via the same tool (which is a 2 min task) to check if I can get OTA again.
And yes it worked! immediately after changing the OTA to its home CSC, was able to see OTA in the updates section of the phone. So, I updated the phone to the latest version (DVL9) and then changed the CSC back to INU after the update . All is well and quick! .

May be TUR csc has restricted options/features. In my example after I changed to INU csc (India one) all the India related options got automatically activated like call recording, spam filter, samsung pay using cards etc etc. which weren't available with the EUX csc before the change.

Any potential issues using INU csc in the UK? I use Samsung pay already but native call recoding would be really useful for me

Might be worth clearing cache and data from Google play services see if that helps. Having the same device with 2 different cscs might have confused Google
Edit
Any reason your Google play store is out of date or is it connected to your original issue
