Question A02s Flashing question - Samsung Galaxy A02s

I have an A025U from Metro, unlocked. Due to AT&T's new regs, they only accept the A025U1.
Is is possible to flash the U to U1 on this model ? I have tried two different (new) firmwares that both
fail the PIT.
Is there a generic firmware out there that would work for this model ?

Flash a different Region

I know the question has been here before, but i dont seem to find a answer on my specific question:
I'm the Owner of a Galaxy S9+ - It's a "NEE" region
I want to flash the German (DBT) region firmware. Will this mess up the phones KNOX? It's official firmware from Sammy
Flashing a different region firmware, will this mess up the "modem" regarding the bands and etc.? I live in Denmark
I wish you all to have a great day out there
You can flash dbt version with no problem! Knox will not be affected and your csc will be nee !!!

Question Canadian A52 5G SM-526W Call recording CSC

Hi,
I'm able to flash the Canadian A52 5G SM-526W with the stock firmware successfully using Odin both the complete firmware and just the CSC.
I tried to flash with SM-A526B, SM-A525M, SM-A525F unsuccessfully, it fails every time for the complete firmware or just the CSC.
Can anyone direct me to which firmware I can flash to this phone to activate the built in call recorder?
Thanks!
Indian/INS firmware should likely have it, but don't flash A525 firmware on the A526, you'll have problems.
I did try flashing with the A525 firmware but it just fails.
How can I use the Indian/INS firmware to add call recording to my phone? I tried to use just the CSC file with Odin from A525 firmware and that failed too.
You could try using the XSG (United Emirates Arab) firmware. I have it on my J7 Pro and it has the call recording function, not sure if it is the same for the A52 5G.
I'd suggest you flash the original firmware that came with your device first, then only flashing the CSC from the XSG firmware to see if you get call recording.
And use Frija to get the firmware, just go into its settings and turn on "Binary Nature" option for it to download the 5 part firmware instead of the 1 part firmware.
Sorry my bad, I didn't know there was a SM-A526W for the Canadian market only. I was thinking that your's was a SM-A526B, which is the international version. I don't know if the A526W will accept the A526B firmware, it might work or it might brick your phone.
Thanks for the help, it wouldn't accept the CSC from the SM-A526B firmware or the entire firmware already tried that. Any other suggestion?
Then no, you're pretty much stuck. I don't know whether any of the other Canadian firmwares have call recording enabled.
None of the Canadian firmware's have call recording and I have tried a number of different CSC using the *#272*IMEI# method which are available in the firmware. Guess its a no go

W models can typically only flash W U and U1 firmware
It will only flash W firmware which I have done several times, but it will not flash U firmware or even U firmware CSC file

maybe if you posted the error you receive in patched odinas wellas the error it shows on device screen when it fails then we can help u
for example, if it gives a sha hash error or something its bcuz u arent using modified odin which is needed to flash u or u firmware to your w model and if it gives some error like sw rev check fail its because youre trying to downgrade and need a firmware with the same rev
Here are the pictures I blocked out the DID number
Was looking through the forums and would using a Thailand SIM change the CSC so I could have call recording?

Your SIM card does not set or change CSC.
I was reading this thread:
https://forum.xda-developers.com/t/a52s-change-csc-by-factory-reseting-with-a-sim.4360199/
Could I try the same?

Question Change CSC via ADB

any ideas to change CSC with ADB
I would think. That if you loaded up recovery, and then switched to the side load mode.
That you would be able to flash an official stock CSC file from a different 4-File/5-File repair package of another build. As long as as that CSC File matched the BL's software revision fuse.
Generally speaking, Samsung Devices have been "World Modem" compatible since the Galaxy S7. So carrier firmware is interchangable on the same SoC.
And if flashing the CSC alone does not work Try using the UserData.img as well
If all else fails just install the U1 FW, or whole 5-File Repair package from another carrier that matches your device's BL Revision.
This hasn't failed since maybe 2015.

Can you give me your model number real quick to see if I can't find you a link?
This is what I found first off: https://forum.xda-developers.com/t/...sc-firmware-need-to-be-on-one-ui-2-5.4182989/
Not sure of it's usefulness on your device but sounds like it.
Otherwise. Find the U1/XAA fw for your BL Revision and flash it with Odin.
It should then be compatible with ALL CSC CODES.

Hi, I may be late here but if you still looking to change the CSC on your Samsung A52s or any other phone I will suggest you visit this link, you can ask any question related to the change of Samsung CSC if you are a professional, for normal users just place your order and get it done remotely.

Usual methods not working. Can't determine CSC.

I have been unable to detect the CSC of my Tab S3 LDU before flashing it. There's nothing in Software information or Discovery and the DRParser doesn't respond to the *#1234# code at all.
I have a SM-T820 LDU which still runs Android 7.0 and I'd like to flash it to Samsung's Android 9 firmware for this model, but I don't want to brick my device.
1) Is it safe to flash a new firmware if its CSC and geographic region is different than the current one? (Flashing a UK firmware over a German one, for example.)
2) If this is asking for trouble, what way might I figure out the CSC of my current firmware other than the methods listed above?
