I received a free Samsung S6 Edge from some friends. The phone had a busted battery which I fixed. The phone is still on the original 5.1.1 that the phone was released with.
When I try to do updates it says DM initialization not ready. Check network or SIM card. When I received the phone I was told it doesn't work with cell service. I checked to make sure and it definitely doesn't. There are no options for cell service in settings or the drop-down menu. This phone is missing IMEI numbers, IMEISV numbers, and baseband versions too. The only way I found out the IMEI number was it was printed on the back of the phone.
I am fairly certain the problems are software-based and not the motherboard but I don't know enough about phones to be sure. Do you guys know? I also want to remove AT&T from the phone to install a custom ROM on the device. (There is no OEM unlock in the developer options) Can I flash SM-925F firmware on the device to make it factory unlocked or will this brick the device? Will flashing the original SM-925A firmware fix the problems with the device? Please let me know if you need any more information to answer my question.
I found this: //G925A\\ Nougat 7.0.1 Latest Stock ATT Odin files G925AUCS7ERC1 | XDA Developers Forums (xda-developers.com) Should I flash this on my device? Will it fix any of the problems I had on it?
Can I flash the SM-925F firmware? Is the hardware of the factory unlocked phone and AT&T versions the same or will it brick this phone if I flash it?
Since the phone is AT&T you'll have to go through AT&T for the unlock codes before you can flash anything other than an AT&T ROM. To my knowledge there are no custom ROMS for the S6 Edge, but I could be mistaken.

I know this phone is old news however, I actually have the S6 and S7 edge lying around and so i got bored lol...here is my dilemma; Evidently the phone (S6 Edge G925A) had an abnormal factory reset, which is a load of BS, and now I can not get that security detail, which you know calling Samsung always ends to NO AVAIL!! I have flashed with Odin the firmware that my device is on the ERC1 firmware and still I get stuck @abnormal reset. I've searched numerous sites, different forums and still to no avail. Something told me inside that you was the man to drop a line to, any leads or info will be more than appreciated brother...Thanks for your time....
PSSS....
I got my unlock code from AT&T some time ago but the code is 16 digits long and code only takes 8 digits, and of course to hear AT&T tell it, " I simply must not putting the code in correctly"...lmao
Is it safe to change the CSC so we can use a Samsung image that's less bloated? My version has O2 apps installed and I'd rather reclaim that space for something else, or at least not have to look at it.
Change CSC on Samsung Devices | Guide | iHax
Looking for a way to change CSC/Country Specific Code on your Samsung Galaxy device? Here's a quick guide on how to do it easily.
ihax.io
I don't know about other regions, but in the USA region, I beleive the SIM card will set the CSC for you, and not allow it to change. In some cases, even that doesn't work properly (I had to return a phone because it wouldn't switch). Maybe you have more control in other regions or with Exynos phones...
Just tried the key combo and no dice, got a message that said 'that function is not supported' or something like that. I asked a question elsewhere here - what would happen if I were to just flash a different Android 12 firmware version on this phone? Right now, the phone is O2U, would I brick if I used XAA (US)?
I don't know what key combo you're talking about. As I mentioned, in the USA region, the SIM determines the CSC. What type of phone do you have (Exynos vs Snapdragon) as this could affect things as well?
If you flash a snapdragon ROM onto an Exynos phone, I imagine you're going to have problems. I don't know if that bricks it, but I wouldn't be surprised if it does.

Yoooooo I'm going through same issue. Look you can flash any firmware Purdy much as long as the binaries are the same im trying to root a galaxy a13 5g from MetroPCS that only has two months activation in and its beating my ass. I was able to do some kinda unlock on it coz now it says device is corrupted dm-verity can't be trusted but I still don't have oem unlock displayed in developer options I've flashed t-mobile,Verizon,MetroPCS, and now I'm on Canadian firmware which is supposed to be unbranded but because MetroPCS has the network lock on it it hasn't mattered what I've flashed because I even had it XAA by flashing the a5150 csc tar file trying to root this funding piece of suit phone but to no avail.unless I get the network unlock icant get the bootloader unlock option,tried vbmeta image no verity no force encrypt every Magisk version boot image patched even tried different device with same chip and set up... impossible broski if you phone is network unlocked and you are able to unlock bootloader so you can bypass vaultkeeper/avb/secureboot/vbmeta/dmverity/prism.img....etc etc etc and with root access only then can you change and/or modify any part of a samsung device as far as my knowledge and experience goes

Samsung Tab S8+ won't update via wifi, I get a server error message when I try, last worked in June and since then it hasn't worked. Tried clearing cache, restarting and everything else I can think of. Contact Samsung, I'm just saying phew... not much help there. Anyone have a solution to the problem?
My Samsung Tab S7+ 5G is working fine on wifi, no problems at all.
Hi. To be 100% clear, you don't have the bootloader unlocked, and you're not rooted, correct? (Although I wouldn't necessarily expect the problem you're facing with both of those things)
Bootloader locked, no root, just like straight out of the box.
What CSC (Country Specific Code) is your Tab S8+? Quoting another user on here - I don't remember who:
Go to settings > about > software information > service provider SW ver
The region code (CSC) will be written there.

And what specific model number?
I don't really have any specific suggestion other than a factory reset, which I know is extreme, and wouldn't guarantee to fix the issue. You could always use the SamFirm or Frija Windows programs to manually download the firmware, and use Odin to flash it. As long as it's the completely stock Samsung firmware of any type for this device, it will work without unlocking the bootloader.
Hello! good morning, I have a Samsung Note 8 SM-N950U, which I wanted to install a custom ROM to get out of android 9, the problem is that the OEM unlock option does not appear on my device, I tried to change the date and update but It has not worked, I tried to change the CSC of ATT that comes by default but when using SamFW it tells me that there are no other CSC for my device, even on the web page, there is no solution for these problems or a way to install a custom one ROM, if someone can give me an answer I would greatly appreciate it.
Have you considered buying a rooted version of this phone on ebay or asking any people that sell rooting services on ebay?
Hi, im kinda desperate cause i really dont know what to do , here is my issue:
I bought a second hand s20fe i didnt know but its rooted and i want to remove it
The problem is that i tried booting it to download mode removing the root and trying to flash a original samsung stock firmware from odin, but it keep getting a error. Well i realized that the phone original model is SM G780G
And that the software that it had , was the SM G780F
So i downloaded a software for the G780F and apparently it worked with odin
But i want the original G780G software... what can i do?

I'm pretty sure your problem is:
you want to install a system with wrong binary.
Go into download mode and see what binary you have.
After you are sure which binary has downloaded the system you need and that's it.
if you have binary 3
upgrade to binary 3
If you can show a photo of what binary you have to observe.
Binario 1

I would like to tell you the full problem tho if you are so kind to give me a hand. I bought the s20fe second hand and it was rooted with a patched imei (the box and the software imei didnt match), i checked both imei and they are not blocked , so the phone isnt stolen. But here is the thing, the model in the box says 780G, and this software is 780F, the soft and the imei doesnt match. I tried rooting and unrooting, but now i dont have signal and i still have the same imei and software version, i would like to switch to the original imei cause im sure im able to use it , as well i would like to install the proper software version.

the equipment is not G780G.
1.G780G goes up to binary 4
2.G781B arrives
up to binary 5
3.G781U /U1 /V / N / W . go up to binary A(10)
4.G780F reaches binary A(10)
your equipment is a G780F and not a G780G. You can never load a system from another team, only from your variant.
Download an example system:
G780FXXUAFWB6
Currently there is the binary B(11).
luck.
unfortunately
it was advisable to leave it as it was when buying it.
if everything worked fine, there was no need to update.
just leave it with the system that was already installed.
since to change the imei, chimeratools, z3x is used. etc
They are paid applications and experience is required for it.
I used the z3x, that's why I'm telling you.
I dont understand, cause the model is in the back of the phone...

It didnt worked fine tho, i had a very low signal, now that i made a mess of course i would love to be back, but i dont know how to install a signal patch and i doubt that samsung would help me if im out of warranty, so i basically lost half of my saves on a phone that i can barely use now... what a luck

Personally, it is impossible to install an exynos system on a snapdragon.
It's like putting the engine from one car to another, just like that.
the cover says one thing, your phone another.
the caps are interchangeable.
Those can be put from an s20 fe exynos to a snapdragon.
check well.
personally you have a G780F.
try not to upload to binary B(11)
you will have to pay to solve the problem.
install software that it had initially, if the system was binary 9, it will be impossible.

the interchangeable cap make sense and also solve the imei trouble, i will choose to believe in your experience. But logically, then the email should be the one that is on the software right? and not in the cap? i already installed that version you told me, but how can i restore the signal? i just need to restore that and i will be able to sleep cause ive been awake almost 10 hours trying to figure out this mess
I really don't know if you can fix it.
I think your equipment was only rooted. The signal always worked.
I never touched the imei of your equipment.
It may even be that you are presenting a software error. once going to binary B. you will not be able to return to binary A.
if the problem does not recover without any update. It could be a problem with the internal antennas.
that they are disconnected.
I realized the problem, the case was switched indeed. And the original imei was changed because it was blocked. Since i update to the most recent binary and there is no chance to downgrade that, i wont be able to use sim cards anymore or at least until there is a new versión for patching the signal. I dont know which program the technicians use so i dont know if im ever going to recover the phone. An awful purchase and a even better movement from my part trying to update the android and removing the root. Im just disappointed, i hope this thread helps someone to not make the same mistakes...
At this point i dont even mind to pay for a signal patch, but there isnt a update for the system they use to do it. If someone knows anything about it, would be pretty helpful.
I understand what you're saying:
As a technician I understand.
Always before making changes, you have to know what we are getting into.
If you already knew that the imei was repaired and patched, for nothing in the world to update.
as advice, do not upgrade to binary B
stay in binary A.
The solution will come out, it always comes out for computers with an unlockable bootloader.
stay on february patch one ui 5.1 with binary A.
The rest are security updates.
Before listening to me, check that the system does not contain bugs.
in the best of cases, repair and sell, buy a G780G or G781B
luck.
