Warranty Void

Hey,
I have samsung galaxy A5 A520F/DS UAE version.I have attached its original Firmware details.In order to use jio voice of over lte i have updated INU Indian firmware.Now my device
Droped and receiver is not working.I want to claim warranty.In samsung info now my firmware details show multi csc and my baseband chaged.
My Question is
1.Will i get warrenty if i just download and flash XSG uae firmware through Odin ?
2.Will it change my base band to original version ?
3.I Don't know wheather its UAE XSG OR LYS.is there any way to know this from screenshots attached ?
Sorry unable to add attachments it fails please reply with provided information.i can't share even image link because am new user.
And how do i attach screenshot

Please reply

1- there is no picture attached .
2- flashing official firmware does not void the warranty as it does not trigger knox switch.
3- Better use the modem attached with the firmware as they are optimized to work together and avoid triggering knox while flashing only one component of the firmware.
4- You can find weather it is XSG or LYS only in recovery and not in software information.

Note 10+ firmware problem

Hello
I've bought Note 10+ 5g, From about phone>software info It was with code (SM-N975F) and 2-SIM work well and fully support Arabic language.
When I entered DOWNLOAD mode, I found the product name is SM-N976N and Carrier id id KOO.
I've flashed the latest version of SM-N975F and the device worked without Arabic, and the 2-SIMs BOTH don't work, at all.
Now, I'm downloading SM-N976Q, which is directed to Suadia Arabia, which support Arabic, BUT I'm NOT SURE if it might support 2-SIMs to work.
I'm in this problem since 3 days. What is ur opinion?
Thanks in advance

I also have same problem , I have bought SM-N976N but I think the company had flashed SM-N975F firmware in it before and it was running android 11os I think it's refurbished course I don't receive update nor security updates, so I tried updating it firmware manually using odin from android 11 to android 12 model number SM-N975 firmware , but doesn't work it refused to flash with error saying repetition fail .
I have now flashed it with KOO version of SM-N976N android 12 but my problem is that the phone is not recognizing sims or carrier in it (not even 3G or 4G) I'm from Nigeria.
So my question is , how can I flash back N975f cz my region will be covered in it. Because samsung has not launched a PAK version of firmware of SM-N976N.
Please help how will I be able to get my sims working in Nigeria with or without root? Please help anyone.

Model Code = SM-F926UZKXTMB
Software Version SAOMC_SM-F926U_OYN_TMB_13_0011 TMB/TMB, TMB/XAU/TMB
now i want to remove t-mobile option from it and make it normal also i want to install magisk and root it so i can explore more functions..
as per my research i need to download firmware and then update it with magisk zip img and then install it via ODIN..
my question is to change it from T-Mobile to normal which firmware should i use? and do i need to change CSC also?
EDIT 1: after some research i found out i need to install SM-F926U1 for unlocked version and my CSC CODE for phone is currently TMB but XAA is official unbranded CSC for USA so i am going to download XAA BASED SM-F926U1 firmware and will install it via odin will update here.. if someone see this thread before and i am doing something wrong let me knw
