Any ideas as to why I can't downgrade? Thanks.

It's not possible to downgrade due to security changes made in its system.

Can I still use custom firmware as long as it runs off Lollipop?

Rooted?
Custom Recovery?
Probably. You'll need to check the other threads for your specific model. As you can see, I'm running the Sprint S5 Sport or SM-G860P.

My phone is rooted as of now, but I'm not sure what custom recovery is... yet. I'll do my research on that. Thanks.

You can't downgrade from this firmware.

Hey,
I'm having the same problem..
Does anyone have a nandroid backup for 4.4 or 4.2? I think that should work
Thanks in advance,

Noone reads.
You cannot run or flash an older rom or firmware if your phone is running firmware newer than OA6.

Right? Lol. O further elaborate tho, the bootloader prevents older versions from being flashed or from running. That's just how it is. I can't even remember how many downgrade threads I have read -.-

Yes, you can go back to OG1 using Samsung Kies 3.

I was able to install Clockworkmod recovery on Galaxy S5 SM-G900P running lollipop OG1 firmware using this method and then flash a custom 4.4.4 and 4.4.2 roms with recovery mode and flash NE5(for 4.4.2) and NK4(4.4.4) kernels with odin and also flash NE5 modem in order to install SSU.apk (Samsung Sprint Unlock) which unlocked the phone but i did not get a signal with T-Mobile sim card and with more research i found out that this unlock is not made for in USA but for international use.

Yes you can if you install clockworkmod recovery but you can't flash roms (stock or costom) with odin from download mode anymore if you have OG1 and higher i think because i tried flashing stock roms with odin even when i was on costom rom, it would always say fail.

Which rom did you try to flash with odin? OG1 or earlier version?
So if I flash a custom 4.4 rom through CWM, can I flash back to OG1 by odin later? Sorry because I ask too much, but Sprint 5.0 is too confusing @@

I tried flashing 4.4.2 and 4.4.4 stock roms and a few other costom roms with odin, all of them failed. I haven't tried 5.0 with odin though. You could use Samsung Kies 3 to go back to latest android version of the phone but the phone has to be turned on since i don't think samsung kies will detect the phone if it is recovery mode or download mode.

Is that possible?

Whenever I restore from Kies I no longer have wifi calling. Does anyone else have this issue?

so there's no way to downgrade from running fusion ROM 5.1.1 to OA6?

i update my phone from 4.4.2 to 5 ok4 latest fw
and i lost my network
any solution?
can i downgrade to 4.4.2???????????

Odin NAND write fail and white/electric noise during calls

Here's my problem which I was trying to fix for a week now. I got a Galaxy S6 (G920FXXU3COI9 - international) which was working fine but I decided to make some improvements (tmobile wifi calling, etc). So, I decided to root the phone with new kernel (S6-UniBase_BOG8_v2) and then put a new ROM in (Rapture 2.1, my build became G920TUV2COF8). And everything works fine but when I make phone calls on tmobile tower I'm getting nasty while noise (but wifi calling, viber, etc, work just fine. 4G network works fine too but it looks like phone reception is kinda low).
So, I decided to try another ROM or change modem/BL files but Odin 3.10.7 (and 1.8) cannot pass NAND write stage. On another hand, I was able to change kernels. I also tried to reinstall samsung drivers and use another USB port - same result. Trying to flash with new BL/modem throws error on the phone "SW rev check fail device: 3 binary: 2" which doesn't show up when I try to flash ROM.
Any ideas on how to fix noise or change ROM to international or T-Mobile one? I suspect that I'm using incompatible files somewhere but I tried 4 different ROMs with the same results.

Failed in sboot.bin means your flashing an older bootloader.
Sorry to say but you cant downgrade your bootloader.
Your phone has COI9 based from what you said. Where did you get the modem/bootloader file? Im suspecting it is not on COI9 bootloader.
Just flash a latest stock firmware from sam firmware to get the latest bootloader.

thanks. Thants what I thought the problem is. Can you send me the link for the latest bootloader/modem I can flash on my phone.
Do you think I can use T-mobile ROM with my international edition phone?

Dude, Im just using my phone right now, Just search your exact phone model in sammobile and download the whole firmware.
SamMobile provides original/verified/stock full firmwarw for your device. They wouldnt upload a single bootloader or modem img or bin files.
Maybe someone can share their extracted sboot.bin based from COI9. Just be sure to convert it to flashable odin file before flashing or else youll be facing some problems again. Or better, a ready made flashable odin bootloader based from COI9.

Many thanks, man.
I found the firmware on sams mobile but they have 5 different ones for PDA: G920FXXU3COJ1; I'm confused with CSC code. Thats why I was asking for a direct link.
Excuse my ignorance but by "convert it to flashable odin file" you mean .img to md5 conversion or something else?
And, one more question, I guess it is not a good idea to change ROM from 920F to 920T, or I should try few more 920T before giving up?

Hmm why would you want to flash a TMo version??? If I were you, just stick with your current ROM.
There is no direct link for sammobile, just forget what I've said with COI9 build number, just download the latest firmware for your region. If you find any file just pick the latest date and youll do good. It contains the latest bootloader for your phone.
Md5 thing is just for the checksum for odin. It is added for verification and its the most praticed and suggested way of creating ODIN flashable files.. But IMG will do good.

ok, finally got it fix, sorta.
Rapture 2.1 ROM gave me loud white noise during calls but the rest was working fine. The post says to flash the phone with BL and Modem files but Odin failed (I assume since I have newer BL already). So, I went back with latest G920FXX stock ROM and the phone works fine.

Can I downgrade to 5.1.1 from 6.0.1?

As title says, can i downgrade to 5.1.1 from 6.0.1? My phone is G920F. Will there be issues with bootloader? On sammobile forum, they said to me that downgrade is not possible because of bootloader.

Yes you can downgrade without any issues

can you tell me how to enter recovery mode from odin download?

first download the 5.1.1 stock rom
second run odin
third enter download mode using three buttons
forth click start
fifth when finished enter recovery using volume up home and power button
last do a wipe system and cache and reboot

yes, i know that, in odin i must ucheck autoreboot, but when finished installing the firmware, it stays in download mode, what is combitation of buttons to enter recovery mode directly from download mode

I'm currently using XtreStoLite Deo Mod v.2.4 - XXU3COI9 with engineering bootloader, root and knox 0x0. Can I clean install some stock MM ROM without tripping the flag and can I go back from MM to the mentioned ROM (5.1.1) with engineering bootloader without tripping the flag or damaging the phone in any way? Is it possible did any1 tried it? I know that if you update your bootloader to COI9 or higher version you won't be able to use engineering bootloader anymore, which means no root with knox 0x0 on 5.1.1.

Done, I put Lp following the instructions above, all ok.
After the flash of fw the phone goes into bootloop, just go into recovery and make various wipe.
For me the LP look is better and I have dozens of settings in more than MM.
Thanks.

So you were on stock android 6.0.1 with marshmallow bootloader installed on Galaxy S6 and you downgraded to lollipop 5.1.1 and flashed engineering bootloader again and Knox is 0x0? I'm asking because I just want to make sure. I want to install some stock MM but I don't know yet if I will be able to live without root and want to know if I can go back to my previous ROM and bootloader, without tripping the flag.

I was on mm6.0.1 , I downloaded the very first 5.1.1 fw from sammobile but everytime I try to flash ,odin says 'Fail'
can anyone please help me with this?

+ 1.

I was on MM update and downgrade to LP because I liked the old stock clock widget.
Mainly because of my old themes work better with LP update.
MM clock widget is crap doesn't change shape or size with your themes. Plus the MM stock clock widget shadow is gone.
No special effects on lock screen either like bobble effects with MM update.
I hope they fix old themes to work with android 7 and bring back the old clock widget weather.
Who else likes the old LP update? I used December android 5.1.1
(XEU). Europe firmware

What version of MM were coming?
Thank you.
I tried but it does not work from G920FXXS4DPG2, Odin said FAIL.

hi, i upgraded my s6 to one of the latest builds of marshmallow, now i want to downgrade to lollipop.
when i flash with odin, it gets every time an error (with hidden). If i flash the lollipop bootloader, it stops the flash at half, and it fails...
so it's impossible for me to downgrade! i tried installing xtrestolite (lollipop version) but it stucks at "Samsung Galaxy S6", so it is in a bootloop....
how to solve?

I'm trying to solve my main problem and decided to downgrade from 6.0.1 (G920FXXU4DPH7_G920FTEN4DPH1_G920FXXU4DPFY_HOME.tar.md5) to 5.1.1 (G920FXXU3QOLH_G920FTEN3QOL2_G920FXXU3QOKD_HOME.tar.md5) unfortunately it fails:

So ummmm... Slight noob here. I searched this thread (http://forum.xda-developers.com/gal...e-deodexed-mod-edition-1-0-t3094423/page1630) to see if it works on G920p and found comments saying it does. Being overjoyed I flashed it. Ran into touchscreen problems so I flashed the correct kernel. It works pretty good except I don't have root for whatever reason. I tried cf auto root... No go. So I just wanted to back to stock and give up finding Roms for this device BUT Odin keeps giving me a fail message like this

You can encounter that problem when PIT or modem or bootloader are incorect for a rom version you're trying to flash with Odin. Did you manually flashed some modem/bootloader when you were flashing that custom rom? And which version of stock rom are you trying to flash with Odin?

No i didn't install anything besides the ROM. I tried installing all the MM files for the s6 found here http://updato.com/firmware-archive-select-model?r=SPR&v=Marshmallow(Android+6.0.1)&q=SM-G920P. It used to work before i flashed this ROM. Now i get a "fail" message every time.

Have you tried the firmware that officially came with yours?
I had once the same problem with a friends G925F which I tried the latest version of MM on and had the same issue. When installing back the firmware of our country it succeeded.
And you can always try Smart Switch the Emergency Recovery function.

Question How to flash a different model firmware (i.e. SM908E onto a phone currently running SM9080)

Hi everyone,
I do have a Snapdragon S22 Ultra that is currently running SM9080.
However, non of the CSC versions available for this firmware has eSim support.
Therefore I would like to try flashing the SM908E firmware (which should have eSim support) and which is also a snapdragen hardware.
My problem right now is that ODIN does not flash the different firmware onto the phone, so I'm looking for help on how to technically do that.
What I've tried so far:
Tried to flash BL/AP/CP/CSC files *without* "re-partition" option enabled.
This gives the error "Re-Partition operation failed."
Tried to flash BL/AP/CP/CSC files *with* "re-partion" option enables and a PIT file selected.
This ends up with Odin reporting "SetupConnection..." and then basically freezing for some time until it reports "Complete(Write) operation failed."
Note the Device is currently not yet rooted.
So I'm a little bit lost now what the problem is and how to do the next step ....
Any suggestions or ideas are highly welcome!

Further info: I've now also tried to
unlock the bootloader
root the AP file with magisk
Nothing helps to.
I can flash e.g. a magisk-rooted firmware SM-S9080 but I can't flash S908E.
This is the error message that I get when trying to use the "re-format" option and also select the PIT file.

You should just be able to flash the home csc in Odin. I currently have a 908e with the 908w csc installed this way.

I suggest you flash twrp if you want to change different model.

Try with a Patched Odin? https://forum.xda-developers.com/t/patched-odin-3-13-1.3762572/

Any look over here?

No luck so far ...
Tried the "patched Odin" -> same propblem
Tried to flash only the CSC file with ODIN -> doesn't work
Installed TWRP according to this guide Link but when I try to install any of firmware ZIP files then I get the error message that the ZIP file is not okay.
So what help now would be if I know how I can use TWRP to maybe flash one of the downlaoded firmware files.
Any idea?
