Samsung A3 2017 Firmware update - Upgrading, Modifying and Unlocking

Hi Team,
I would like to replace the firmware of my SM-A320F/DS with the European SM-A320FL. As it is Dual Sim phone and I am using the second sim slot for external memory card - 250GB.
Is it going to work? I do not need the second sim option but I need the external card slot.
Many thanks,

Usually is not a good idea to flash firmware for a different model. But let's other say if it will work or not.

[Q] bug in sim card

Hello, I need help installed the rom "cm-12-20150211-NIGHTLY-nicki," and there was a bug in the sim card, the ROM does not recognize the chip.
My device is the Xperia M Dual C2004.
not quite sure what you mean, if you can't detect sim card, take sim out and clean any dust (if any) and put it back in, if its still not detected flash the radios for 4.3

Changing Galaxy A5 (SM-A520F) into dual sim varient.

Is it possible to change single sim variant into dual sim just by flashing dual sim rom and change sim card tray?
Of course not. There's no reader inside for second SIM. And you can't flash firmware for different phone to yours.

About my SIM card slot

Hello everyone,I'm from china so forgive my English
I have a problem recently and seems there's no other guys have this issue as same as mine.
My device has been unlocked and rooted,and I've flashed a unofficial ROM based on H2OS,and then the most weird thing is my SIM card slot 1 just can not work normally.
The specifically situation is,(I'm pretty sure that both of my SIM cards can work normally and one of them is a brand new one.) when I use the slot 1 only,every time I put the card in and after about 5 hrs then my device just can not read the SIM card,it shows up no SIM card inside,and it can't be solved if I reboot my device. I have to take the SIM card out and put it in again and after about 5 hrs it shows no cards in again like a loop.
And then I have tried my card slot 2, lucky for me it can be used well, none issues.
The third situation is when I use both my SIM cards,after bout 5hrs
It still shows up no cards in, both slot 1&2. And I still have to take the cards out then put them in again or I can just use the slot 2 only to avoid this weird situation.
And now the latest news is I used twrp to root my device again and now it seems everything works fine in slot 1, but I have to wait for 5hrs to make sure of this.
Oh I forgot one thing, once I tried to uninstall xposed but it seems nothing to do with my SIM card slot 1 problem
it shows up again!
No SIM card inside when I use the slot1 only.
it really upset me now and don't know how to solve this problem.
I may have had a similar problem. Sim1 would forget that I had a card installed every hour or so. Sim2 would forget there was a card installed once or twice a day. The only thing that would fix it was reseating the card and rebooting the phone. I suspect a loose Sim card tray and had to RMA my phone.

have you fixed the problem after RMA?I've already bought a new tray and waiting to try
I'm still awaiting my replacement phone. I will let you know when it comes in.
Just an update: the new phone works fine. It's safe to say that my first phone had hardware problems.

Sim card tray slot problem - there seems to be something in your sim card tray

Hi All,
Would it be possible on root'ed phone to block message which started to pop up after latest upgrade about use of 2xSIM cards + SD Card?
The message blocks completely use of all three at the same time whilst was perfectly working prior update (reports from other users confirm this):
The message says:
"Sim card tray slot problem" there seems to be something in your sim card tray that doesn't belong there"
And overlays completely screen - nothing else is possible.
More details with screenshots under this thread:
https://forum.xda-developers.com/galaxy-s9/help/s9-plus-update-stops-dual-sim-memory-t3813436
It has to be possible - and I truly hope someone can do that, maybe Xposed or something with Magisk could help?
Any hints are more than welcome as currently I've had to pull out second Sim card with SDCard out of the phone (they are glued).
Version which brought this issue first is: G960FXXU2BRG/960FOXM2BRG4/960FXXU2BRG4, size 580.93 MB
Unfortunately I do not know what was original out of the box version. Manufacturing date is: 2018.05.21
Thanks!

Forgot to say, yes, I'll try to do this with Odin (unless anything else recommended) as short term workaround, though it is more important for a long term.
All new releases will include this and the issue is to find long-term fix, hopefully Xposed or Magisk. The issue is that Samsung guys read this forum too and instead of helping, they're blocking us - I've used to use S7 with 2xSIMs and MicroSD without issues for more than a year and was super happy with everything.
On S9 situation - detection seems to be done on logical level, as combos slided into the slot where SD card is covered with thin plastic film, as expected SD card is not detected and both SIM cards work fine. This only proofs that there's no "pressure" sensor and all seems to be verified at logical level, i.e. if SD card and SIM card in Slot 2 is detected at the same time - block usage and popup that nasty message.
Question remains open - how to block that message and be able to use SD cards and SIM in slot 2. Hopefully one of devs might help.
Please see below thread where a lot of people showing their interest to get this fixed, preferably by Samsung, though I'm sure if someone could deliver a fix based on Magisk it would be more than welcome, even if it would require root.

It got blocked from Samsung. If you're rooted yoi can just flash the file to enable it again
SOLVED.
Phone rooted and installed fixes, see:

one more thing to try to really determine that for sure is - there are people who filed the sd card n sim card thinner and glue them together without using the extender - if theirs' the same now means really is Samsung

I had a s9 with oreo and it worked perfectly two SIMs with SD glued. Now I have a note9 and I got stuck in the pie with binary 2 and I can not return to oreo, which is binary 1. Anyone has any idea how I can get rid of this "Sim card tray slot problem .... There seems to be something in your SIM card tray slot that does not belong there ... " on android pie? I'm very upset with this

I just tested another Note 9, now with oreo 8.0.1, security pacth of 08/01/2018. It did not work either. Therefore, no stock rom of Note 9 (Oreo 8.0.1) will accept two sims and SD card at the same time. It seems that root is really the only alternative.

Dual SIM S9 shown as SM-G960F

I got a Dual Sim S9 with 2 working SIM slots.
Phone info only shows G960F instead of G960FD/S...
I tried the 2 SIM AND SDCARD hack.. but the sdcard ain't showing up. Using Soldiers PIE ROM with SDCARD MOD installed.
It's even not shown in TWRP.
