[Q] extracting firmware from S8500

Hi,
I was wondering if there is any way to extract the firmware from my S8500T handset? I'm wanting to do this as there is no copy of this firmware available and I want it as a back-up in case things go wrong with flashing to other firmwares.
my S8500T runs S8500MBJF2, S8500HUTJF2
any ideas?
thanks!

What country / provider is your phone?

@ beigebullet
Please post Product Code you see this via sTune. Something like this : GT-S8500BAADBT
So I could try something...
About your Question.
Not impossible, but only JTAG known to dump Firmware.
Best Regards

Ah do you mean 'Product Name'? In sTune all I get is xxxxxxxxxxxx.
I've manually changed my CSC from HUT (ie. Three Hutchison australia) to KOR but I can change that back if needed...
I've uploaded a pic of what it shows me

Ah do you mean 'Product Name'?

Yes, correct.
xxxxxxxx I saw several times.
This means NV item 2757 (HEX Value) is empty.
Kies without valid Product Code do nothing.
Best Regards
P.S:
S8500T
Attention!
I'm not sure. But for instance S8500R seems to have problems with normal Firmware... maybe incompatibility.

Hmm, so can I somehow get a valid Product Code from Samsung?
And yes, the S8500T is not compatible with normal firmware, as the T version runs on 850/2100Mhz bands, not the 900/2100 on standard firmware. This is the reason I want to extract the firmware from my phone, as I'd like it for a backup.
Thanks for your help adfree

Create a new CSC... Possible?

I know, that this might be a strange idea...
We know, bada has languages, preconfigurations and keyboards for different countries...
But we also know, that everything depends on the CSC (e.g. INU, DBT, XEO,...)
My intention is to create a complete new CSC...
For Example: ATU for AT&T in USA...
Just in theory...
Maybe one of the experts has an idea, if there is an algorithm for checking CSC...
Maybe it is possible to modify bada in that way, that it can handle "Custom-CSCs"...

If you mean preconfiguration only then yes it is possible
You just need to know some info about the network you are making CSC for
Also edit another CSC preconfiguration and don't make your file from scratch
Just specify the network you want to make the preconfiguration for and i'll try to help you
Best Regards

Why you need it?
you alredy have CSC for a lots of networks..
I mean that you have the CSC for you own network. Whay you need to work about something that exists.
Sorry if I didnt understand your idea.
Sory for my ENGLISH...

taxidriver05 idea isn't strange
new CSC exemple: there isn't CSC preconfigaration for the new operator FREE France

Okay
This sounds good
Can you please provide network configuration profiles ??
I am ready to make that CSC profile...maybe i'll call it FFR (If Samsung didn't already give it a name)
I'll take care of the rest...just network config is required
As a start the MCC/MNC of Free France is either 20814 or 20815
This code is for the phone to show network name in Lock screen & Status bar

Sorry it's in French...

Free France CSC is ready (or i hope so)
There was no server ip or port no. on the website that Soxix provided (Thanks for that...my french is so poor and this was a great help )
Only for FW developers
Please try this CSC profile if you have a Free France SIM card to test with
I guess that files will talk about itself
Best Regards

Let's see, if it works...

[Q] Korean Version SHV-370K - ROM/GroupPlay/ChatON

Hey people,
I recently purchased a Korean variant of the S4 Mini. The model is SHV-370K. To my findings, its equal to the main version I9195. Is that correct? I do have the NFC chip installed. My question is, can I flash an official ROM like the ones used in the I9195? I have to much KOREAN language apps and I dont think I am prepared to root it. If I can flash an official ROM on this via ODIN?, will I still be able to get the OTA? My current version is 4.2.2. And checking on Sammobile I have the latest. The Korean stuff is just to much of a hassel and I am not sure if I will even get an update. Can I flash an official ROM and not lose warranty and root?
My second question is that I cannot make Group Play work on 2 of these S4 Mini's. They just dont connect. It says Network Lost and sometimes failed to join group. I've tried working it over with NFC and Wifi Direct. Normal gallery pictures and everything send easy, just this app that I really really want to use. Would be great if some one would help me.
My last question is that ChatON keeps giving an Error while checking for push services. I have tried everything. Changed networks, tried Mobile Networks. All my apps are up to date, even the annoying Samsung Push Service. Any help would be greatly appreciated.
Thank you so much people.
Have a great day.
Oh and I think its Carrier Branded? Cuz it has this Olleh writen on its back cover?

So ChatON and Group Play is working after they have been updated most recently. I did update them before but they dint seem to work. The current updates work good. Any one about the ROM issue? Would love some help <3.

you can only use a korean K rom, or a modify rom for the K version, otherwise you can brick your phone.

Hi guys,
Have you found any solution to this problem? I'm also an [almost] happy owner of a Korean-branded S4 Mini and as USSD codes don't work, was told that firmware needs to be changed. But this being specifically a Korean phone, I'm not sure other ROMs out there will even be 100% compatible.
Thanks,
Vit

you have to enter it's secret menu, and insert the password, each network has it's own password.

Thanks, but I don't think I have to enter a password, since other phones work without it. Unless it's somehow phone-specific, but my operator reps would probably have told me (instead they just said the firmware needs to be changed). What secret menu are we talking about? perhaps aI could investigate. At any rate, if there someone has managed to flash the Korean version of the phone with a more "universal" firmware, I'd like to know. Thanks!

This secret menu allows you to modify the network, frequencies and other stuff, each korean service privider has it's own password.
try typing this on the dialer.

you don't need the menu for the ussd, korean version has their own set of ussd, they are different from the international version, some are the same , but most are different.

Please forgive me as I'm a total noob, but after your last reply it hit me: we're probably talking about different USSDs. I meant that my operator USSD codes didn't work, the ones that I send to find out my remaining balance and to also enable/disable services etc. (e.g. I would send *444#2#1 to find out my remaining balance), not the phone's own USSD codes (like the service menus etc, e.g. the IMEI check with *#06#). Operator USSD codes just don't work - the phone either sits trying to connect for a few minutes (locking the phone down during this time), or just says that the signal is too weak. So I guess I do need to install a different firmware to fully unlock it.
Thanks for trying to help though, I'm learning new stuff!

Mate I have the same problem here. The USSD codes just dont work. My balance check does work though. All I have noticed that USSDS that need two steps dont work. Example to transfer credits, I type *456# and in return it should ask me what number I need to transfer my credits, but it just doesnt work. I have tried the menu but no idea what that is all about. Still cannot find what to do.
Secondly I met some one at the forums who has the same device as ours. HE said installing Cynogen Mod is working and it doesnt effect us having a model of SHV something. LOL. So I dont know if I should go ahead and flash a custom rom. I would rather flash an official rom but no one is helping here and I cant seem to find any. Like maybe we could flash an english rom from UK. Something official like the normal I9195 have! Not some korean ones.

New Update.
Hey people! I just got an OTA update and all I see new is a Google Drive icon. The update is still on 4.2.2 and not 4.3. It was about 96mb of file size. How can I take out the changelog and read what bug fixes it brings?

hello
how to do I move from SHV or change the CSC code?
for now getting only the Korean pop up messages.
Want to change to Australia CSC code.

I've read about CSC Select app (on google play market), but I think you need root for this to work. I'm not an expert on that though.
Please write here if you manage to get any results (even if negative).

Changing CSC SM-R825F from Hungary to UK

Hi!
I've been lurking this forum for a while and am really eager to change my Galaxy Watch Active 2 CSC from Hungary to UK to make Samsung Pay work. I have a Curve card specially for this but I've been too afraid to do it because I'm afraid I will lose the 4G functionality of my Hungarian Telekom provider.
Right now my watch is set up with Telekom and has 4G set up as esim.
My big question is if I change my CSC to UK, will I lose the 4G functionality? Will I still be able to connect to my Hungarian esim account?
Please let me know, any information is greatly appreciated!!

I did it, Samsung Pay worked, but it doesn't connect to the Telekom network. Then I also made the mistake of wanting to re-register the eSIM, but it no longer allows me to try any available ROM. Now I should get the factory Telekom ROM, but I have no idea where it comes from. It sucks. Very big sucks.

Theory.
ESIM is activated and work. :good:
IMHO eSIM profile will not be erased.
So IMHO eSIM is lowest problem.
But SPay chance 50 / 50...
Maybe your plan will NOT work for Samsung Pay...
Best Regards

Hi Adfree,
First of all I want to thank you for your reply and all the work you are doing for this community. You are by far THE Galaxy watch expert. You're always commenting constructive feedback to people.
Everywhere I see your comments and helping out people. A big THANK YOU!
I will try to change the CSC, even though I'm a big newbie to this.
One last question: will I be able to revert the watch to its original state if it turns out it doesn't work? With that I mean original firmware that it came with?

To increase your chance to get Original Status... my suggestion:
A
Check Firmware infos on your device to be 99,9 % sure what you need...
Type like you would call someone:
Code:
*#1234#
Then you see all relevant infos to find your Firmware...
B
For Orignal Settings... my suggestion with SDB Tool from here:
https://forum.xda-developers.com/showpost.php?p=74585286&postcount=330
B.1
Check Bootloader Version sboot.bin
Code:
cat /proc/cmdline
B.2
Check active CSC
Code:
cat /csa/csc/csc-active-customer.inf
B.3
Check Product Code
Code:
cat /csa/imei/prodcode.dat
You can save these infos with Screenshot or by Copy and Paste Text only... with right Mouse Button.

How to enable e-sim

I looked around a lot on the forum and from what ive understood theres a way to do it by changing the csc or smthg. But im an absolute noob and dont know what any of this means. Can somebody give me a ste by step guide on how to enable the e-sim. I currently have a SM-G985F/DS

On pc: download samkey from org site (just google it)
Download and install samsung usb driver
Buy credit (you need only one)
On your phone:
Enable developer mode and adb
Remove sim card and all sort of lockscreen
Connect phone on pc, open samkey app and click on read info (phone will show up a popup asking for some permission, just consent)
Now looking on samkey interface you will see a text box named csc. Wrote there a csc having esim enabled (like btu) and click on wrote csc.
Just click there and you are done.
This will work only if you have dual sim variant, then should enable esim. If you have single sim variant, so you will have only csc changed without esim enabled

Is there no other way to do it without paying more money. Im aldready tight on cash.
I really cant cough up the money for credits.

If you are already on lastest security update no.
If you dont ever update your phone and your firmware is on bit 2 or lower, there is a modded theme that open a secret menu to change csc for free.
Nvm 1 credit is selled on ebay around 2.99$
