Downgrading 920F from 6.0 back to 5.1.1 - Galaxy S6 Q&A, Help & Troubleshooting

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

Hello hoglak
I have a 920I and was also having the same problem.
I solved the problem flashing the latest version of the rom from SamMobile site.
After flashing the rom your TWRP should work.

I had the same problem. The latest firmware for unbranded (XSA) Australia on sammobile is AOC4. I had success with using the Singapore unbranded (XSP) firmware AOD1.
Flash AOD1 with Odin then you have stock everything. You should be able to flash TWRP 2.8.6.2 with Odin and boot successfully into Custom recovery.
You can either take two options from here.
Flash CF-Root and "just root" the stock ROM - Boot into Download (again) and then flash the CF Root.
Flash a ROM or a Mod which has Root included. - My first success was Wiping with stock recovery, flashing AOD1 clean with Odin, then flashing WanamMod on top of it as it included root.
Aussie G920i.
Hope this helps.

Can you root without TWRP?

sorry if duplicate, couldn't find any answers...
Can you root G955F without installing TWRP?
I'd like to know that too
Hi,
Yes with CF-Auto-Root you keep the stock recovery, you'll need to be on AQDG firmware: https://autoroot.chainfire.eu/ (search for the SM-G955F file), device will be wiped. Reported working in French forum, just need to do a full wipe manually when the phone ask to after reboot and reflash CF-Auto-Root, after that all will be fine.

Yess.. easier is to check zip. In it is tar.md5. This you can flash via DownMod Odin.
Full Wipe

Update firmware without lose any data.

hello guys!
I have a SM-G950FD (ZTO) rooted by magisk and TWRP recovery.
I need to perform updates by flash a zip or donwload via odin.
The problem is: when I try to update a firmware downloaded on Sammobile (tar.md5) via Odin it changes my recovery causing to lose all data.
This happen because on firmware that I donwload on Sammobile have a stock recovey included. Otherwise, if I use HOME_CSC will also cause lose data because of change on recovery.
I try a lot of things like, remove recovery file from the tar.md5, also try use Abyssal Kitchen, but I can't have sucess.
I ask for help plz! I just need upgrade my firmware without lose data by flash a update.zip or donwload a .tar via Odin using a firmware that I donwload from Sammobile.
Kind regards!

2022_VZW_EMMC_15_Chipset For Unlocked Dev BL To Downgrade To LL_KK Or Upgrade To MM_And Keep Unlock Bootloader

This Process Will Update Or Downgrade Your VZW EMMC Chipset DEV Aboot Bootloader Unlocked S5 To Marshmallow 6.0 Lollipop 5.0 Or Kitkat 4.2 or 4.4
​Root And Unlock Instructions Can Be Found Here
EMMC 15 Rooting And Bootloader Unlocking
EMMC 11 Rooting And Bootloader Updating Or Downgrading
Explanation On This Process
To update bootloaders to a newer or older bootloaders all moddified system firmware must be put back to stock in order for the bootloader to update. There is some kind of check and a flag is thrown if there is a modded boot or recovery image present. This is why it is a 2 step process and why it cannot simply be a one zip process. You are on unlocked bootloader and have TWRP probably install and maybe a custom boot.img. To upgrade bootloaders the stock recovery and boot images must be put back to stock and when you do this you obviously do not have a way to flash the zip to update rom and bootloaders. because there is no more custom recovery installed. So too do this the first zip removes TWRP and puts back Stock recovery and boot images and also adds safestrap recovery which is a system based recovery. Then when booted to safestrap recovery you can flash the rom zip with bootloader update and it will flash properly because there is no modified boot or recovery image then once the zip is flashed it removes safestrap and puts back TWRP recovery. Now the reason there is a 2 different Files To Prepair To Upgrade Or Downgrade one for kitkat and one for Lollipop/Marshmallow is the safestrap needs to be different for the kitkat system vs the lollipop/marshmallow system which can use the same safestrap. This is the reason on zip does not work for all 3 systems

You Must Be On VZW EMMC Chipset 15 With DEV Aboot Unlocked Bootloader With TWRP Recovery
1. Choose the file from the Download Files To Prepair To Upgrade Or Downgrade above that matches your current firmware and place on phone

3. Reboot too TWRP recovery and choose install and choose EMMC_15_TWRP_**_Prepare_Dev_BL_UP_Dwngrd.zip and install. Do not wipe anything at this point just flash. This zip will remove TWRP recovery and replace any it and your boot image with stock boot images and install safestrap to your system which is needed to upgrade or downgrade bootloaders. When down flashing phone will reboot phone to Safestrap Recovery which looks just like TWRP recovery.
4. In Safestrap recovery choose install and choose the EMMC_15_SS_Install_***_*_*_*_**_Bootloader_Unlock_AIO_Rom.zip you copied to your phone. This zip will install proper bootloaders and firmware and rom and TWRP again. Do Not wipe anything at this point just flash the zip. Once zip is finished flashing phone will power off.
5. Now reboot phone to TWRP recovery which will now be back on your phone and goto wipe and choose advanced wipe and wipe data only. Then reboot phone and you are done
Bugs Problems And Tips
All roms are deodexed so they will take a long time to boot up to 20 minutes or maybe longer the first time or if you wipe dalvik cache or data
When Rom is booting up if your key lights come on and stay on why the rom is on bootanimation the entire time and waiting for rom to boot then this means your bootloader is not matched to firmware. I suggest trying above process
Fingerprint will not work on kitkat roms and may not work on others
All above roms use the QL1 baseband you are free to use any baseband you want however the Non-Hlos file must match firmware so only flash modem file
If you flash modded boot images it may break root
If you loose bootloader unlock or wish too start fresh go here first https://forum.xda-developers.com/ve...-emmc-15-chipset-onlyroot-bootloader-t4009089
If simply wanting to reflash an above rom zip over same rom and firmware it is ok too just flash it in TWRP you can skip the EMMC_15_TWRP_**_Prepare_Dev_BL_UP_Dwngrd.zip
All above methods are for Samsung Stock roms I do not offer support or answer questions about flashing Lineage or AOSP based roms
Tools And Extras
