Hello,

I'm trying to downgrade Samsung Note5 to 3 firmware earlier. OS version is Android 7.0 I accomplished downdrade it to just an earlier firmware same security patch installed. But the others tries has failed. During flashing firmware (Hidden img or cm.img) ODIN says Fail. I've flashed the firmware with PIT file extracted form the device but same results happened. Is this result related to pit file or ODIN?

Do you have any advice to downgrade the device to any firmware that i want. Which methods and tools should i use?

Data loss is not important for me. 

Thank you..

Not 100% sure on Note 5, but in general with current Samsung phones you can't downgrade past certain bootloader version.

 

For example, N920CXXU5CRL3 - this is so-called binary 5. You can only flash firmware files with 5 in this spot or higher. N920CXXS4CRC2 - this is binary 4 firmware. It won't flash if phone currently has binary 5 firmware installed. There should be a message about it on bootloader screen.

Downgrade is limited by the firmwares versioning. If you modify those to pass, then you brake the vendor signature and certificates. So this is a trap, don't do it! Better upgrade to a signed firmware with root capabilities, upgrading was never a problem 🙂

@passcodeunlock Thank you for your reply. The device is password protected. (secure startup not enabled) I tried to extract device image with Oxygen, Ufed4PC, XRY but the device firmware is not supported. So i tried to downgrade firmware, maybe downgraded version would be supported. But i couldn't. Do you have any advice to extract image? Thank you.
