Unknown IMEI Number after Stock Firmware Flash - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hello,
ive got a S6 edge (SM-G925F) from someone with lineageos 14 installed. The Sim Card hadnt been recognized from the start, so i thought i flash the stock Firmware to reset it.
Even after flashing various stock Firmwares, the Sim card doesnt get recognized. There is also no IMEI and IMEISV Number. Its just unknown.
I tried flashing
-DBT Germany Firmware
- O2 Firmware
- Vodafone Firmware
all with the same Result.
Does someone know a fix?
PDA: G925FXXS5EQL1
CSC: G925FOXA5EQL1

[Q] ODIN writing error when flashing to another country's stock ROM

I tried quite a number of times trying to flash my S2 that I got from HK to a stock docomo ROM but it keeps failing at the FactoryFS part. Anyone got some ideas on why it doesn't flash? (is it hardware related?)
what version of phone do you have ?
go to settings - about phone post model number, versions.
I suspect that your phone may not be able to handle docomo rom becuase it is not a Japanese version but another country which does not have the correct board for docomo.

[Q] firmware update problem sg3 sgh-t999

I just bought a phone on ebay. unlocked samsung galaxy s3 sgh-t999. It's supposed to be brand new and was in the orig. box. But the build of the firmware is ZS and in kies it says
PDA:EMC
PHONE: LK3
CSC: EMC (CHN) <- CHN I presume is China
also my android is 4.1.1 and I would like it to be at least 4.1.2 preferably 4.3
but of course OTA doesn't work because of the country code. It says registering device then processing failed.
I've tried to flash using odin but I get aboot error with some roms and in some versions as well as sbl2 error with some roms and some versions.
and my phone in download mode says it's an I747 -- the at&t model. In gs3->settings->about device it says its a sgh-t999 which is what it should be.
Kies says the firmware is up to date. arg frustrating.
Everything about this phone works except for updating the firmware.
So I asked for a replacement...which I got today. Same stupid problem, not only that, but this one isn't recognizing my cut micro sim. So if it's between the 2 I would like the original one since it recognizes the sim.
I have read that I can change the country code, but I do not want to root the phone since I want it under warranty.
what should I do to update my phone?
Thank you for any and all help

Really strange issue with CSC / Baseband / IMEI

I have a really strange problem going off here and I am hoping that a few people in the know can help.
On my ongoing saga / quest or even visit in to the twilight zome trying to get my phone repaired I have come up on a new issue.
I have managed to get the phone to boot using this ROM - KIES_HOME_I9300XXELL4_I9300OXAELL4_566833_REV00_user_low_ship.tar which I flashed via odin.
I ended up having my baseband back reporting as - I9300XXELL4 and the infamous IMEI coming up as 0049*.
Now I run terminal emulator this is what I have
getprop ro.bootloader - I9300XXUGMK6
getprop ro.baseband - unknown
Then when I run samsung phone info I get the following
CSC INFO
Original CSC code - KOR
Firmwares CSC code - KOR
Active CSC code - KOR
CSC country - Korea
CSC Country ISO - blank
Product code - GT-I9300RWDEUR
The Korea part baffles me as everytime I have downloaded a ROM I have looked for BTU as I am in the UK and from the digging I have done this phone was unlocked.
So even to someone like me with very limited knowledge of this sort of stuff, it looks like I have a combination of a 4.3 Bootloader and 4.1.2 system which could be stopping me from getting my IMEI up?
Would flashing a MK6 BTU Modem ( as I am in the UK ) through Odin work?
Unknown baseband means hardware failure, csc is unimportant.
To set the csc to match firmware you need to factory reset in recovery, after flashing.

So in phone settings it is showing as the I9300XXELL4 baseband however in terminal emulator it is unknown what does that mean?

[Q] CSC code "partially" changed

I flashed a different stock firmware on my Samsung Galaxy Alpha. Previously I was on ORO but now I use DBT. To check the CSC I did the following:
dial *#1234# -> I see the correct DBT values: "AP: G850FXXU2BNK1", "CP: G850FXXU1BNK1", "CSC: G850FDBT2BNK1",
changed the values in the "efs/imei/mps_code.dat" and "system/csc/sales_code.dat" files to DBT.
booted in recovery and there I see it's applying DBT
However, Kies3 is showing a 4th value, which is still stuck on ORO. This is confirmed by the "Phone INFO" app, which shows "Product Code: SM-G850FZWEORO". DBT got just the other days an update, but Kies3 is telling me there isn't any. I've tried using a plethora of CSC changing apps but was unsuccessful.
What am I doing wrong and how can I completely change the CSC?
Resolved
It seams that the solution to "completely" change the CSC after flashing a new firmware is to do a factory reset of the phone. Of course all the data gets erased, but that's what backups are for.
After the factory reset, there's no track of the old CSC. Keis sees the device correctly on the new CSC.

Anybody know how to change CSC on Android 12?

Hi all...
I recently flashed BTU Android 12 firmware on my XFA Galaxy S10e (exynos). Everything went perfectly, it defaulted back to XFA...
Then tried the same thing on my Galaxy S20 FE (exynos) (also installed the BTU Android 12 firmware), and am now struggling. The firmware first defaulted to Russia (SER). I was able to downgrade back to Android 11 (BL 8 for both) but then the CSC defaulted to Turkey (TUR).
Now, no matter what I do, I cannot get it back to XFA, or anything other CSC for that matter. It's stuck on TUR, no matter what region of firmware I install. Even tried XFE which is not an OXM CSC and it still went back to TUR. And I cannot currently use Samsung Pay.
I cannot use SamKey as my work laptop won't let me install it (Endpoint Security quarantines it).
Does anybody have a reliable method I can follow to change it back to XFA.
I've tried flashing, even using the pit file and doing nand erase with no luck. The codes on the dialer don't work either. I've also tried flashing various firmwares such as BTU and XFE with no luck.

Mine is a Galaxy S20 FE G780F, do you have the same phone as me? I did manage to fix mine, read on to find out how.
This was not easy for me to fix. I tried samkey on someone elses laptop and wasted 2 credits because it did not work. I selected XFA on samkey and it went to SER (Russia). Second time it stayed on SER.
Downgraded to Android 11 XFA, and it got stuck on TUR (Turkey) again. No matter what I tried, it would not change from TUR.
I tried flashing pit files, rebooting with different sim cards, factory resetting many times as well as flashing about 10 firmwares both on Android 11 and 12. Still was stuck on TUR.
I then decided to flash the Australian firmware for Android 12. When the phone booted up, it was actually English. I thought it was fixed, but no, it was then on Indonesia. Atleast everything was English but samsung pay would still not work.
I then flashed the stock XFE (Samsung unbranded - South Africa) firmware and boom!!! When the phone booted everything was back to XFA.
I now have Samsung Pay as well as the latest security update which is not even out yet via OTA.
Only issue I'm experiencing now is bad battery life and the phone heats up a lot with light usage. So I'm still pissed
