N920S Lollipop Downgrade

[Wise.Guy]

Hello all,

I have an N920S, SK Telekom, and i've done OTA update on Marshmallow. I don't like it and i want to downgrade to Lollipop. I've tried everything with stock firmware of N920S but everytime a click START on Odinit gives me FAIL from the beginning. Even installed TWRP, wipe everything, even DATA, the phone remained without OS but still can't install 5.1.1, only 6.0.1. Can anyone help me with this problem? It can be done downgrading to Lollipop on N920S?

Thank you in advance for your responses.

Yes you can downgrade! You should search the forums before giving incorrect information out.

You need to use the absolute correct firmware in order to downgrade! Make sure OEM is enabled and Debugging also before trying to flash anything.

Follow my instructions here but substitute the Verizon firmware for your own.

I've already tried this with 3 official 5.1.1 ROMs of N920S SK Telecom, the first 3 5.1.1 ROMs that appeared. But when i click START on ODIN it gives me FAIL about 3 seconds from the start, and on the phone a message appears: Sw rev check fail device 2 binary 1. Maybe i'm doing something wrong. From Phone Info Samsung i got these: SM-N920S 64 GB, 23.10.2015, KNOX 0X1, on product code and original csc code i got nothing, firmware's csc code: SKC, active csc code: SKC.

Because you tripped knox you have to flash everything in the slots BL, AP etc etc.. you should unzip the firmware and find a guide that shows you how to flash them 1 by 1 by putting them in the correct slots in odin.

Also done this. I found an official 5.1.1 ROM with 4 files, AP, BL, CP, CSC and the Pit file, but nothing, the error is the same. I begin to think that on N920S this method doesn't work.

LE: It worked with another ROMA file. Thank you for your advice.

Glad you got it working! This is just more proof that other carriers can downgrade!
