Downgrading 920F from 6.0 back to 5.1.1

Hello. I've been using android 6.0 for a while now, but I'm not very fond of it, and I'd like to downgrade back to 5.1.1 stock so I can root and install custom Roms.
I've searched and found nothing, so how do I it?
Downloading UK 920F firmware gives me a zip file with 5 different files. Are there any particular order I must flash them with odin?

what are the files?

AP_G920FXXU3COI9_CL5816106_QB6438203_REV02_user_low_ship.tar.md5
BL_G920FXXU3COI9_CL5816106_QB6438203_REV02_user_low_ship.tar.md5
CP_G920FXXU3COI9_CL5816106_QB6438203_REV02_user_low_ship.tar.md5
CSC_BTU_G920FBTU3COJ1_CL5868306_QB6555338_REV02_user_low_ship.tar.md5
So, 4 files.
I just want to get back to 5.1.1 so I can root and install xtrestolite without any problems.

thats how i did it
try downloading this zip
http://www.sammobile.com/firmwares/confirm/62892/G920FXXU3QOLD_G920FTEF3QOL1_VIA
extract it and flash the .tar.md5 over odin (AP)
reboot to downloadmode and flash the twrp recovery
boot into recovery
(backup optional)
wipe dalvik cache, cache, and data
now flash the xtrestolite in the recovery and reboot

But I need to flash bootloader and modem also, since I was on 6.0?

no i think that's all included in the .tar.md5

How do I know that the version you linked me is the right one for me?

you have an sm-g920f ?

Yes, unbranded.

so i'm no developer but i have the same device and i did it in the same way so why shouldn't it work?

Did you downgrade from 6.0 aswell?

Want to give an update:
The best way to do this is using Samsung Smart Switch and following the instructions when plugging in the phone.
Problem solved.

Now I am on 6.0.1 beta. Does this trip the KNOX counter? I must downgrade to 5.1.1 to claim warranty

you dont need to flash 5 files. Just flash OI9 BL，and then flash 2.8.7.1 twrp. then flash 5.1.1 custom rom

[Q]how to flash OTA package with twrp?

i have new recovery twrp(decryption support) installed and also patched boot.img with root, now i want to flash update_data_hw_full package and an ota update.zip package, which is stock firmware. can i flash it with patched boot? or do i need to flash stock boot.img first? and will flashing this firmware with twrp work? bcz it is an OTA package

No, TWRP can't flash stock Huawei packages, you'll need the stock recovery.
You may also need stock boot.img, not sure, I don't use it.

Once i flashed those nougat files with twrp and its all working good. But thats an old ver of MM twrp..
Haven't tried the new one.

Flashing stock boot.img should do the job.

Ok, where can I find this for B389?

Download the firmware finder and search for b389 and download update.zip and extract it using huawei update extractor and extract boot.img and flash the image using twrp.
Or ask some one give the boot backup

i did flash the stock boot.img but it gets into bootloop

Update you twrp to the latest stable version for you phone,, then reboot to recovery and make a full wipe,, after that flash any aosp based rom on your device and gapps

I have the same problem, for any reason TWRP does not allow me to flash any ROM because my phone is recognized with no name, gonna try this and come back.

ur csc is bad, had the exact same thing a year ago,
just install twrp again
flash csc pack (if there are csc packs for snapdragon variant), flash any csc u want , i did it twice just to be sure
and after that go flash stock firmaware with same csc code
so if you install btu csc then flash the btu firmware with odin afterwards,
dont flash the home_csc .tar in odin just choose the normal csc thats in ur firmware folder
hopefully this works for you too mate

damn, well i dont know what you can do then maybe try combi frimware, should have root acces add see if you can flash that way?
dunno just trying to help

Factory resets and try to flash the rom again I don't think it's a baseband issue like exy.
Make sure what needs to be clicked in Odin from the instructions are clicked too

Still having problems
