[Q] How to downgrade J700F to 5.1.1 after november update(MM)

Hey guys since I upgraded my J700F to the latest version with october security patch
I dont seem to be able ti downgrade my phone to 5.1.1
I tried some ways including deleting 2 files from 5.1.1 rom and fkash but no luck
Everytime i get this error in downloading mode:
sw rev check fail device 1 binary 0
Please someone give me a step by step guide to downgrade to 5.1.1
Thanks
Flash using odin
I guess you will have to do it using odin. Search these forums for the guide. I saw it around here. Use search man. Thanks.
Download the firmware of 5.1.1 of j700f from sam mobiles website and flash it with odin
please i need some help too can't downgrade it from mm to lp.. i read on some tread that the new mm bootloader did that
When boost mobile and sprint and virgin mobile updated their j7s from f3 to ph4 they did the samething but on 6.0.1. What they did was stop the flashing of the older rom which did not have the Asks software security. When you flash a older android version such as 5.0 over a new android version such as 6.0 the flash is declined. You cant downgrade cause the bootloader prevents it thats why theres a error message in odin.. not really sure why youd want 5.0 over 6.0.

Your Odin error is due to flashing older firmware version ( Bootloader)
The firmware you mentioned above is the latest version 3 bootloader so you should be able to flash that.
Latest version firmware is G955FXXU4CRI5 (September with bootloader ver 4) if you want to update to the latest firmware.
Flashing the firmware will replace your recovery.
You can use this to find the latest firmware for your phone

Back to stock from kernel v. 8?

Hello all,
It is possible to go back to stock Samsung from Android 10.0? Whenever I try to flash the software via Odin I am met with a rev. fail device 8 kernel 2 error.
You are trying to flash a very old firmware on your device which has a recently updated bootloader, you can only flash the same firmware as the bootloader, or a more recent.
You can't downgrade, at least not to v2.
