A Samsung combination file is different from a stock firmware and can’t be used as a daily driver unless you are a developer testing or working on the phone’s software.
To get your phone back to the original state, please download and install the official stock firmware.
No, it’s not compatible and can’t be flashed.
Yes, the combination file size is sometimes half the size of the official stock firmware. This is because the factory binary file has been stripped down to only have engineer functions and not to be used s a full ROM.

Sí, hay una solución. Es posible que su Samsung S6 Edge sm-g925i tenga un problema relacionado con la red. Pero primero, ¿actualizó manualmente el archivo de actualización de software 7.0 o fue una actualización OTA (Over The Air) que instaló a través de la pestaña de actualizaciones de software del teléfono?

Did you flash a factory binary or a normal stock firmware?
Samsung A70 SM-A705FN/DS. I have replaced my motherboard due to water damage and now am getting a message that the fingerprint sensor needs calibrating. I understand I can ‘reset’ this by using some of the tools and tests on the combination firmware. When I try to apply the firmware I get a ‘Failed (Auth)’ error in Odin and on the phone it states “Please get the approval to use factory binaries (pit)’ I have enabled debugging mode and OEM unlock prior to connecting to Odin. Can you help?
To use the combination firmware on most of these newer devices, you will need a compatible pit file. Have you tried flashing a 4 file firmware to your device, factory reset, and then check the fingerprint sensor again?

You can use the Android 9 firmware first and make sure the binary matches your current device firmware.
Yes i have applied the 4 file repair firmware – it resulted in exactly the same issue. I have repeated the steps with the stock firmware and, again, same result – however i used the latest Android 10 binaries, I will try with the Android 9 and see if that makes any difference. Are there PIT files available somewhere to enable me to apply the combination firmware?
Okay. No pit files available for now. Please try the Android 9 firmware and let me know how it goes.
I have downoaded a zip file but in it are just 2 .xlsx., 1 xml.zip and a folder that contains files but I cant find the combination file inside the zip. please advise me on what to do that i may use the combination file to flash using odin.
