[Q] How to downgrade J700F to 5.1.1 after november update(MM) - Samsung Galaxy J7 Questions & Answers

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.

How to make kies update to 5.1.1 instead of 6.0.1?

So recently, i decided to try and update my rooted custom rom galaxy s5. But i don't want to update to 6.0.1 because rooting won't work for my device model and so i would only like to update to 5.1.1. I cant update it through the phone settings because my firmware/rom was modified. I don't want to flash any stock firmware/rom on my device either because then, i wouldn't be able to update my device through the settings in the future. So what would you guys recommended i do?
Correct me if i am wrong. But if i update my firmware through kies right now, it will use the latest 6.0.1 firmware instead of 5.1.1.

[Completed] Need files to downgrade modem to be able to unlock new security phones

Hello I was just wondering when i go to unlock a new security Samsung running 6.01 or higher
I always encounter error saying try to downgrade modem if possible
I know how to flash phone to downgrade OS to 5.1
But problem is most of these flash files for newer phones do not have flash files for downgrading to 5.1
My question is i read somewhere you can just temporarily downgrade your modem only
Where can i get these downgraded modem files and are they different then full flash 5.1
I am also not sure which option to choose when I open Odin TO DO MODEM ONLY BL AP CP oR csc
Thank you in advance

Regarding Downgrading to Marshmallow from Nougat in Samsung J7 Prime.

Hey I am using Samsung J7 prime and recently i upgraded to Nougat through OTA Update. But after updating my phone to Nougat I am facing certain issues and major issue is regarding Battery Drainage.

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
