I've a SM-A710FD, India model.
I'm trying to downgrade from the MM latest version(BPJ7) to Lollipop.
Every time, I'm getting "SW REV. check fail" in odin.
Some where, i read that the MM of A7 2016 has boot loader locked & so we cannot downgrade.
Please help, somebody !!

But then I'm unable to downgrade it from MM to LP.
Every time I'm getting "SW Rev. check fail" in odin.
I've stock roms for both MM & LP.
Could you please suggest a possible solution.

You can't downgrade revisions. You're stuck with MM.

Are you still using an older version of Odin?
Try using v3.09, and flash the Firmware as AP.

I suggest download first the Russian Firmware and try flashing that. Otherwise your only hope would be to JTAg your phone.
You want to downgrade from 4.4.2 to 4.3 ?
Are you on the new bootloader?

why it is giving error "sw rev check fail device 3 binary 2" ???
If i understand you correctly you want to downgrade from android 4.4.2 to 4.3. That is not possible with odin. You have to flash a custom rom via recovery with a clean install

Hello Guys,
I'm a little bit disappointed with 6.0.1, because a huge battery drain and want to back on old 4.4.4. Indeed it is old, but work really fast and battery life is much better.
Unfortunately bootloader is locked and couldn't successfully flash via Odin KK 4.4.4 firmware.
Do anybody have idea is there a chance to do that?

I'm going to downgrade too and just downloaded 4 files (pit and so on files), but didn't do that yet.
The question is: you tried to downgrade with 4 files or only with 1 file?
Thanks.

You can go back to 5.1.1 but it gets stuck after that. Trying to go back to 5.0.2 doesn't work.

i tried the pit file but not the 4 files method but didn't work , also i removed bootloader file from 4.4.4 sw and flashed it with odin successfully but got boot loop
you can not downgrade your phone to 5.0.1 and 4.4.4 ,samsung has put bootloader lock during COJ5
You can't go back to 4.4.4. You can only downgrade to 5.1.1 coj5.
//Sad for 910C. 910G bl is not locked.
still there is a possible JTAG solution , search it and you might find the methods

Before flashing the firmware you need to flash the marshmallow bootloader and modem for your device then you can successfully flash firmware.

AP I mean sorry. Look at all the boxes you ticked to flash on the right hand side. Only AP should be selected
