I don't know if I enter SM-G970U or SM-G970U1 or SM-G970UZBATMB, and USA or US. With all combinations, it couldn't fetch.

Can I download the specified version? Or should I only be able to download the latest version?

Hello,

When downloading the last release, 0.3.6.6, Widonws Defender flagged it as "Trojan:Win32/Wacatac.B!ml".
It is not the cas with the previous release.

same as SM-G525N, KOO and any other devices and CSC has same issue... Caused by samsung?

The new Galaxy Watch 4 is based on wear OS and Samsung uses the same method as Galaxy phones to check for updates and download. Samfirm succeeds in checking the latest firmware for models but download fails with result code 400. I'm not sure what has changed in the download request but if you could guide me what you need, I might be able to help you with information.

Sample model:
Model number: SM-R885F
CSC: INU

Error: Could not send BinaryInform. Status code 200/400
Request was invalid. Are you sure the input data is correct?
Could not fetch info for SHW-M250S/SKT. Please verify the input or use manual info

this is error message when I using this program for download Galaxy S2 Firmware
Input:
Model: SHW-M250S
Region: SKT

There seems to be a new issue since today (yesterday it was still working normally), see two examples below. It happens, no matter which region or model is used, or if you just want to check or download a firmware. Tested with version 0.3.6.6 and also with 0.3.6.5.

Maybe Samsung has again changed something in their server authentication?

It's great SamFirm Reborn works for SM-T820 & SM-J727U, but SM-G970U (or G970U1) had problems.
    It was bought direct from Samsung as unlocked (false advertising: only carrier-unlocked, not bootloader-unlocked) SM-G970U which Samsung.com calls SM-G970UZBATMB apparently last three letters being region code. However, internally (*#1234#) it's G970U1 (sometimes different than G970U: ) specifically G970U1OYM6HVA1 you said longer string has region code but I couldn't find any matching.
    Entering G970U & TMB in SamFirm Reborn downloaded then said couldn't decrypt: wrong key, then said finished anyway. However, saved .zip.enc4 is unreadable by Windows & 7z: maybe didn't get new key to finish... should I download again or is there a log I can upload to potentially help fix?

And there is also code 403 in Frija.

The story starts all over again, see output from latest version 0.3.6.7 below. I would assume, the fake IMEI (00000000000000) isn't working any longer. Maybe we would need a new input field for specifying a valid IMEI, or we would need a new database in the background, that could select a valid IMEI on its own?

Hello I am assuming you dont mind the project being open source, as such for others to use it legally there needs to be a license. Please read this GitHub article to better understand what I am asking, I have quoted it below.

"You're under no obligation to choose a license. However, without a license, the default copyright laws apply, meaning that you retain all rights to your source code and no one may reproduce, distribute, or create derivative works from your work. If you're creating an open source project, we strongly encourage you to include an open source license. The Open Source Guide provides additional guidance on choosing the correct license for your project."

Can you please add a license to the project, I generally use GPLV2 but whichever is in alignment with your views is fine.

Thank you - MrWicked

Using manual mode yields the same error. Frija doesn't work either. Samfw website is not updating EUX/EUY firmwares.
Other new devices (like A546B, A346B) still work with EUX/EUY though.

normally a dual sim device has 2 IMEIs, do i have to type both of them or only one of them ?
sorry for bad english

Hi,
i can't use your app since the KB5031905 was installed.
