Just to clarify it is possible to put your S7 to PD8 and technically "downgrade" your firmware . So to go from PG1 to PD8 you just need to flash the PD8 bootloader,AP, and CP in Odin.
*Doing this will wipe all your user data*
As far as I know this only works on SM-G930T !!!!
Please try it out and see if it works on your device.
EDIT: I got a video showcasing the whole process, it's a bit lengthy because i wanted to avoid all cuts in the video due the the suspicion that i may be switching devices ...

Well this same thing has been said numerous times before, so do you have proof that it successfully works and also are able to flash other firmware?
As the other user said, if you have proof and can demonstrate how you were able to downgrade, please share with us. As far as I've seen/attempted, this isn't possible because of the bootloader version increment between the new firmware and the older ones.

Have you done this yourself?
AFAIK, downgrading the bootloader isn't possible, as we have already seen in this thread. Please let us know how you were able to accomplish this. Screenshots would be greatly appreciated.

I have done this and will provide screenshots.
Please disregard the G935 version ... I am also running Echoe Rom ... I flashed PG1 Cp,Bl, and Ap . I set it up then I flashed PD8 Cp,Bl and Ap with Odin again ... it was successful no errors. Just to make sure I tried also flashing PB8 but that didn't not work and gave me an error. So I reflashed PD8 and installed Echoe Rom and that is currently where my phone stands. please try it out I need to confirm it works on other devices. I think it works because the PG1 bl is the same version as the PD8 bl. But I can't confirm this. If you tried leave your feedback!

I tried to go from PG1 to PB8 and it didnt work so i tried from PD8 to PB8 but that also didn't work... It seems that it is only possible to go from PG1 to PD8
What is the benefit of downgrading to PD8? Can we flash the 930U firmware after this or it still keeps our bootloader on version 2?

I don't know own which variant the 930U is but There isn't really a benefit besides people saying that PD8 runs better than PG1 or vice versa.

Hey Guys,
I am a proud owner of a new S5 and I am no root newby as I had any other android devices before.
I read that it was possible to downgrade to 4.2 ANE2 Bootloader in order to root with Towelroot, so I might not trigger KNOX
But I read that the ne Models of the S5 have a locked bootloader, so a downgrade to ANE2 is not possible anymore.
Is this strill true?
I would love to see my Phone rooted but if its not possilble (its still in my package lol) I would rather send it back and decide for another phone -.- since I would like to keep my warranty intact.
Appreciate any answers
Regards!
the first thing when you ask put max information about your phone lol y know s5 have many series 900f 900h 900a and ....
Yup, need the model S5 first, then we can check if it can be rooted or not
Hey
it is 900f sorry I did not mention!

Flash this with ODIN
http://download.chainfire.eu/397/CF-Root/CF-Auto-Root/CF-Auto-Root-klte-kltexx-smg900f.zip
If that doesn't work, flash TWRP 2.8.7.0 with ODIN, then flash SuperSu.zip from TWRP recovery
As I said in my beginning post. I would like to have my warranty intact, so I guess rooting with CF Auto Root is not the best Idea, isn't it? (It triggers KNOX)
My Problem is simply, that I would like to know if a downgrade to an earlier bootloader is still possible if the device is delivered with Android 5.0.
You are describing the procedure for towelrooting......flashing an older kernel, using Towelroot and then re - flashing your original kernel. This has worked for many people (myself included) who were on KitKat before they rooted.......
You are on lollipop, this method won't work for you as flashing a KK kernel onto a lollipop firmware will more than likely make the phone unbootable. .....meaning you won't be able to use towelroot at all.
If you want rooted lollipop and knox at 0x0, you'll have to downgrade the entire firmware to KK, towelroot it and use Flashfire to return to your original but root injected lollipop firmware.

Sorry if this a seems to be noob question (but i did not find any answer nowhere).
I want to root my S5 kltexx (G900F) through Odin3_v3.10.7 with TWRP.tar + UPDATE-SuperSU-v2.46.
Q:
What the difference between them (excepting date of publication and version)?:
- openrecovery-twrp-2.8.4.0-klte.tar
- openrecovery-twrp-2.8.4.0-gt-klte.tar
- twrp-2.8.7.0-klte.img
Which should i use?
Thanks in advance for answer.

@triceraptor The 2.8.7.0 seems to be the only version of TWRP that works with some Lollipop firmwares too......
The 'img' file you quoted won't work with odin....you need the .tar version.
Also, make sure re-activation lock is off before you start......otherwise this WILL interfere with the flash.

Hey! Thanks for your post!
My problem is, that it is mentioned that you cannot fully downgrade to KK because the new Devices with Lolli have a locked bootloader. And with that, downgrading to an older KK OS will not do anything because with a modern bootloader its not possible to use towlroot.
So my original intention was simply to find out if it is true - Do the new devices have a locked loader or not.
If your option works, I am glad to try it out, but with a locked loader your advice seems kind of complicated.
To the best of my knowledge. locked bootloaders are carrier specific......
AT&T and (I believe) Verizon are the primary culprits.....There may be 'enhanced security' on newer bootloaders/firmware, but that's a separate issue. If your device is the 'F' variant, which is used mainly in Europe and the UK, a locked bootloader shouldn't be an issue.....It *might* be necessary to flash a .pit file simultaneously to the downgrade though, just to make sure that *every* trace of the LP firmware is removed (this isn't required every time, but is there as an option if needed).
However you play it, it would be best to keep checking to see that re-activation lock is disabled, as this will only lead to issues if it becomes enabled.

I agree with Kieth. I was 90% sure it was carrier specific. You could use the towel root method, but I have rooted my phone the Cf way, and already get 0x1 so there is no point for me. You should be able to flash an older firmware. Then just reset all data and reboot good as old.

Do you know any solutions for it? I would really like to use the towlroot method
Did you downgrade with or without pit?
As I mentioned in my earlier reply, the pit will erase EVERY trace of the old firmware from the device. Just make sure you get the CORRECT pit as flashing the wrong pit has the *potential* to permanently brick your device.

I haven't tried it with a PIT file yet, but ins on my schedule for tomorrow!
Just in Case - I search for tutorials right now - do I have to flash the pit simultaneously or is there any special order I have to do it?
With all my past devices I never had to put so much effort for a root -.-"
Lol.....newer device = bigger headache.
Yes the pit is flashed simultaneously....
Load it into odin as a file with pit extension (kinda obvious that one lol) and then load the firmware tar.....and flash.
Can't stress this enough though.......
MAKE SURE YOU GET THE CORRECT PIT.....
Good luck fella....

Hello,
It's been a long time since I've been these to these forums and an even much longer time since I last had to modify any kind of software on a phone. I recently upgraded to an S7 edge on Sprint and would like to know where to find the tools, roms, and files needed to go to the unlocked firmware version for the S7 edge and go back to Sprint's stock firmware if need be.
More importantly, I'd like to know what risks I encounter especially with Samsung's KNOX. Again, it's been a while so please don't flame.
Any information or direction is very much appreciated.
Thanks in advance!

As far as firmware your somewhat limited as well depending on your current firmware you may only have the latest 935p and 935U to choose from.
P.s you don't have to worry about tripping Knox I've flashed xposed govtuner viper modified Odin tars that failed miserably I'm still 0x0
Thanks for getting back to me vegoja. So as far as flashing the firmware, where can I get the necessary files? I've seen some threads mentioning or linking the ROMs so I think I'm okay there. Also, I think I'm supposed to use a special version of Odin, not sure why. Lastly, where do I get all those other necessary files like the CSC etc.?
Thanks.

Once you flash the U firmware, you can't currently go back to sprint's firmware. Something to do with the upgraded bootloader. But the U firmware is stable and smooth and has good battery performance. You can enable hotspot to without root which is a perk.

935U PI3: https://drive.google.com/file/d/0BzXeLw4AsxZHZlM1OTJZYXBOQW8/view

Thanks for getting back to me. So to make sure I have this correct...I can flash a 935U firmware on my phone and go back to Sprint stock firmware, but it has to be PJ2.
If this is the case, then I have a few additional questions if you don't mind. First, do the AP, BL, CSC, and CP files differ between firmware versions? If so, where do I get those files for each version?
Second, if I go back to Sprint stock firmware PJ2 (which I assume is located here: http://forum.xda-developers.com/spr...rmware-g935p-pe1-official-sprint-6-0-t3414654), will I then be able to follow the standard firmware upgrade path by allowing system updates and going through the standard update process?
Lastly, is there some risk I'm missing or haven't addressed? If I go to unlocked firmware I want to make sure I can always go back to the current Sprint stock firmware.
Thank you again for all the help and information!

Both pathways - 935P firmware & 935U firmware - offer updates via OTA. They're both official Samsung pathways. As of right now, the 935P pathway offers more frequent updates (monthly) opposed to 935U's mostly every other month update cycle.
The most current firmwares on the 935P & 935U pathways are on the same bootloader version. Therefore, one can flash back and forth with no issues. I recently came to PJ2 935P from PI3 935U so I could download the Nougat beta.
The benefit of the 935U firmware is the lack of bloatware which leads to higher performance, smoother UI, better battery life, and easy to add Hotspot functionality.

Hey guys,
since the first flashable firmwares for official Nougat roll out I'm intereseted in upgrading my S7 Edge. Alas I hold off updating in the past, so I'm on 6.0.1 G935FXXU1BPH1 from around september. I have root access and twrp installed and would like to remain that way. The instructions in the big odin firmware thread don't state wether root will be retained or not. Besides I'm on an older version which might result in problems ( I think).
What do you think would be the best way to upgrade?
Flashing firmware using odin would usually wipe data, though not always, and that means you will lose root. Not a big deal anymore as you can always reflash twrp and re-root the same way you obtained it.
It would be helpful to know which thread you're looking at in the first place to advise further.

I approached the OP's initial question on upgrading to Nougat, though it wasn't clear which way he wanted to go, hence the request for ideas on best ways to upgrade.
I've not tried flashing official Nougat using Odin and probably there isn't a need to do so at this time since upgrading from MM to Nougat is possible with the use of twrp and custom roms. It doesn't help that Nougat official firmware is currently only available for 2 regions (BTU and O2C).

Probably you have been using Home_CSC that's why it doesn't wipe your data. Put in the regular CSC tar file and it will wipe your data.
If flashing firmware in Odin doesn't wipe data, how then does the process help your phone recover from a soft brick, effectively returning the phone back to that 'fresh from the oven' state, with the need to re-setup from scratch and reinstall all 3rd-party apps.
I meant this thread, because it seems to be the only one linking to the official Nougat download. Another problem seems to be the HOME_CSC thing where the OP states that I should use the one from my own countries latest firmware (Germany) which isn't available yet for Nougat.

True that. Apart from the United Kingdom region (BTU) and Czech Republic (O2C carrier), official Nougat firmware remains elusive at the time of this post.
From some of the thread posts, it appears that there is no harm using OXA csc, which would mean flashing the entire BTU firmware package. Doing so, however, would wipe your phone data, afterwhich you can stay on BTU until new firmware is released for your region.

OXA csc is included inside official Nougat BTU firmware, downloadable from Sammobile.
You can learn more about TWRP for the S7 Edge from https://forum.xda-developers.com/s7...very-official-twrp-hero2lte-3-0-0-0-t3334084..
With twrp 3.0.2-4, you can then flash custom rom builds based on Nougat 7.0 firmware.

I only ever flash the entire firmware package which is meant for my device/ region. Doing anything other than that may have mixed results and anything to do with altering the csc will wipe your device.
Depending on exactly how you soft bricked your device flashing in odin only may not recover your device and that is when a factory reset may be needed and as mentioned doing that will wipe your device.
It strictly depends on the circumstances.
I have been using odin for years and years across over a dozen devices and have never seen it wipe a device yet.

True that, and as I mentioned earlier it will wipe data USUALLY, except for certain circumstances, for eg. using HOME_CSC instead of a regular CSC tar, for which I must add that the inclusion of HOME_CSC in firmware packages is entirely device/version and region dependent.
Some firmware come in singular files to be flashed using the AP slot only while others are broken into separate files for multi-slot flashing. I'm sure the former will wipe your phone data no questions asked, and the latter if CSC (not HOME_CSC) is flashed in my experience with both package formats.

Edit: Found it! It's PrinceComsy Odin 3.12. It worked perfectly! However, now my fingerprint sensor doesn't work. Is that because I didn't flash bootloader? If I flash just bootloader, will it still wipe the system?
Edit 2: Goddamnit Samsung Pay isn't working either. Says I made unauthorized modifications.
Final Edit: So apparently you have to flash Bootloader as well to get Samsung Pay and fingerprint sensor to work.
Basically, Download PrinceComsy's 3.12 Odin from Verizon Root thread. Then flash the latest G930T ROM from SamMobile. Tick BL, AP, CP, AND CSC. Make sure you ran Odin with admin privileges. It'll wipe internal SD so back that up.

So yesterday I updated from Nougat (not rooted) to Oreo. After I updated I had some issues with my SIM. Basically most of the time I get "Out of service/Not registered in the Network". The SIM is working fine in other Phones. Already tried a reformat (with Stock Recovery) did not help.
So can I just use Odin v3.12 and the S8 Nougat files and flash them?
Will it brick If I do it?
The Oreo Firmware (and my phone) has no carrier. (DBT, Germany)
Same goes for the Nougat Firmware.
Thanks
Phone Info:
- SM-G950F
- Exynos variant
- DBT (unbranded)

Hi, in this case the Knox is altered? I was reading something about the new Oreo bootloader that would not allow the downgrade. Thank you and sorry for my English!

Are the firmwares for G955F and G955FD the same?
My friend has the FD version with G955FXXU1CRB7 - CSC ILO (ISRAEL), but I can't find G955FXXU1AQK7 for the FD version for CSC ILO.
Can I use the firmware for the F variant with Odin?
He is having terrible battery issues with Oreo, wiped data using stock recovery but it won't help.
Downgrade from CRAP (8.0) to AQL5 (7.0) and now I have a DRK error and it automatically starts the recovery, some help?
You can't downgrade via odin. You can only flash the same firmware or higher.
