Downgrading From Nougat to Marshmallow - Samsung Galaxy S7 Questions and Answers

I have a G930A on AT&T (although I think the "A" at the end signifies that) with rooted Nougat. Unfortunately it is extremely laggy, and I am wanting to downgrade from rooted Nougat to rooted Marshmallow (I really don't want to lose root). Is there a way that this can be done? There's a lot of stuff (ROMS, Kernals, etcetera) out there for the Exynos processor, but virtually nothing for Snapdragon. That's super depressing.

Root has nothing to do with downgrading ,also maybe on how your downloading the files its best to use a computer to download as android will only let u download up to 2gb files before it messes them up which varient firmware are u on now and what is ypur originating varient as mine is sprint and had to flash sprint to get to the u firmware

Aye, you can always downgrade using ODIN and Samsung's stock firmware files, although they take super long to complete downloading since the speed is capped -.-.

I'm pretty sure the bootloader did change. I will try going to QC1. Maybe i need to go back in steps?

How can i downgrade qc1 to pl6 or mm , ive been able.to downgrade all n firmware but not not back to mm it fails saying pit file error

90 minutes from SamMobile this morning.

How??? I tried their website once, told me I had to pay or something to get the full download speed, otherwise it would just be capped at around 100 kbps for me *sigh*

updato.com has the same range of firmware that SamMobile has - however, this year they are running a special on high-speed downloads. No registration required, either. Input your model number, download at high speed, profit. (They support download managers, too.)

When I try to downgrade my bootloader I keep getting "sw rev check fail device 2 binary 1" anyone know a way around this?

Do not take APH1 update!

After taking the APH1 update on my phone, I can no longer downgrade to PG5, and I also can't flash the PG9 U firmware. I don't know what Samsung/Verizon did, but it's ridiculous.
I'm now stuck on the APH1 firmware and can't get on the U firmware at all.
I haven't tried rooting, but there is no Odin firmware for APH1 yet, so I'm not going to try until there is, so that if I mess up my phone I can fix it.
What is the full firmware version number? If they updated the bootloader that would explain why you can't downgrade.
It's bootloader v4

Give 3.11.1 a try, I use it all the tome with no problems. It will either flash or not so there is no risk bricking your phone. http://forum.xda-developers.com/verizon-s7-edge/how-to/firmware-verizon-s7-edge-t3344092
Looking at the full firmware name it looks like it's on bootloader v4. None of that will probably work.

Don't bother trying to root... even though I'm not a Verizon customer, it looks like you house have been dicked out of root as you can't go back to previous firmwares and another site I visit says it's been fixed. Sorry guys on Verizon :crying:

Meant to say guys... not house. On another note, this means Aat will probably be getting bootloader v4 soon then too... :/

Well for individuals who did update here is a link to the firmware in case it is needed. https://drive.google.com/open?id=0BybvkLkW8XrDdlRSUGI5Y1VSM3c md5 43E1295CAA08F8E16E873F945728B7D5 @Misterxtc can mirror in the firmware thread if he chooses. But, DO NOT FLASH OR YOU CANNOT DOWNGRADE! The only reason I flashed it was to convert my unlocked T-Mobile Device to Verizon as it was stuck on bootloader 3.
Why would the updated bootloader stop the root? Ru sure? Tmobile had there bootloader updated after the root exploit and was still able to root. It's a developmental kernal, can't see anything on update that would affect the exploit.

If the U firmware gets a upgrade and it's a matching bootloader version as any US carriers bootloader, I would bet it would be able to flash again.

It's not the bootloader that "patches" the root method... it was the security update in PH1 that broke root. The bootloader being V4, prevents you guys from going back to rootable firmware. You now need a new root method which PROBABLY won't happen

Root does work. However you cannot flash U firmware over PH1 simply because there is no U firmware on bootloader v4 yet. Once there is you will be able to.

You might be able to flash a U ROM on top of the PF1 baseband. I was running EchoeRom after updating to PH1 and it was working fine. I flashed my stock PH5 backup to see how that runs now. So far so good.

Hi guys,
yesterday I made update of Renovate ROM like other days. First of all I updated new firmware (G950FXXU1AQG5) and restarted to recovery (via TRWP) again to make rom update. BUT...after firmware update my loved S8+ didnt reboot to recovery but freeze on Samsung LOGO. And now I can only start DOWNLOAD mode. There is no way to go to RECOVERY. No reaction on hotkeys, ADB command line doesnt work too...there is no way how to start RECOVERY mode.
I tried DOWNLOAD mode and ODIN to make firmware uploads again but ALWAYS Odin say <ID:0/007> FAIL! (DeviceInfo). So doesnt matter if I had try to upload firmware or complet stock rom or only BL and CL always ODIN give me error.
Please is there somebody who can help me with this terrible situation. I need my phone for everyday work....
Thanks 2 All

I'm no expert so take this as tip/question.
Are you using the latest Odin 3.12.3? http://odindownload.com/SamsungOdin/
You can download the bootloader AQF7 from here : https://www.androidfilehost.com/?fid=889764386195911671
Possible your tar/md5 is corrupt?
TWRP will be updated to work as soon as Samsung release the kernel source so that it can be updated to work. No ETA unfortunately
Flash a custom "Kernel"!

AQG5 isnt support yet, so phone dont start again like bootloop
download the old Bootloader : BL_G950FXXU1AQF7
https://www.androidfilehost.com/?fid=889764386195911673
maybe CL : modem CP_G950FXXU1AQF7
https://www.androidfilehost.com/?fid=889764386195911675
flash it over Odin , than restart the phone.
good luck

The best we can hope for is that its just enhanced security that can be overcome with the new sources when released. The worst outcome is they've locked the BL and its unlockable like the Snapdragon version which means we'll be stuck on the current BL and will be unable to install new updates that need a new BL.

Well considering that we can downgrade back to the previous BL....we know its not locked. Common sense really.
no need to start posting all over the board the BL is locked unless you have proof of it 100%.

You can't downgrade unless you button mash which is most likely a bug. It's pretty obvious Samsung are trying to stop bootloader unlocking on the Exynos.

Im not sure what you mean exactly...i was talking about simply flashing the previous BL in Odin which people are doing.
And the exynos bootloaders do not and have never required unlocking because they are not locked to begin with.
Further to that this isnt the first time samsung pushed an update that broke twrp and root...its happened lots of times on sammy devices over the years... they will get it fixed no doubt.
Now that's not to say that they arent trying to prevent us from modding our devices...and it may happen at some point that the exynos does get locked...time will tell

It would ruin a lot of peoples phones if they did lock the Exynos versions and would be a very shady move.

Hey,
I also wanted to unroot my phone. I have all the same reasons.
I had upgraded to Oreo before rooting. After root, I had flashed the PartCyborg Rom which was Nougat. My current software version is G955USQU1AQK1.
Also, when I start my phone into downloading mode i noticed a change - RPMB fuse blown which was something different before rooting (Tried attaching an image, but doesnt allow me since I do not have 10 posts)
When I try Odin, it does absolutely nothing. Can someone please help me with the correct firmware file

Except: if you have Oreo, download your firmware here (and not root junky): https://www.sammobile.com/firmwares/galaxy-s8/SM-G950U/

Note:
-Although your ui will will show 80%, you will be able to charge to 100%
-Lose secure folders
-Lose Samsung Pay
How can I get back to G955USQU5CRIB firmware. I think I may have rooted too early. Sprint didn't unlock the phone yet and I'm unable to flash to verizon.
My original plan was to flash from Sprint to Verizon so the phone could be used on that carrier. However, I'm stuck with Sprint software and the phone, although rooted is still locked to Sprint.

The bootloader version is the 5th number from far end of your current firmware 3 or higher cannot be rooted and the only method is partcyborg rom
there is no downgrading or nothing
if you have to have root get another device
you cannot use cf auto root or flash twrp as we have locked bootloaders
if the bootloader gets unlocked then yes cf auto root and junk will work then

Yea, I've had it for so long stock, just upgraded to s10+ and decided to just keep this as a secondary because it's still solid, no a single issue
(long time root user, webOS, epic touch 4g, then all even galaxy S devices) root was so fun!

No im still on a revision 2 bootloader but it's pretty much the same now with the option of installing stock Oreo pie. Or rooted nougat

And there's no way to root without wiping data huh? I was hoping to just add root to my current device, I'll read up too though, I've been out of the root scene for a short bit

More than likely no. I swapped system images a few times. Kinda like dirty flashing and it worked. But errors begin to pile up. One can try. But more than likely user data will be corrupted

Yea, that's what I figured, if I had a better internet, I would start messing around, it takes forever to download anything for me, out in the cuts.. I like to have my Stock firmware files ready to go incase I need to fix a soft brick or something..
Anyhoo, thanks for the posts my friend, I appreciate it!

SM-G930A 6.0.1 unlocked running on T-Mobile flash to SM-G930T 8.0?

Hey guys,
My dad has a SM-G930A 6.0.1 unlocked running on T-Mobile. It is starting to show it's age (battery drain, apps not running like they should, etc.) and is still stuck on 6.0.1.. From my understanding, it should be possible to flash to SM-G930T, however I am a bit lost as to where to begin the process to do so. I tired going straight to 8.0 by flashing the SM-G930T 8.0 firmware files but this didn't work (I didn't think it would work, but it was worth a try). With that said, would it be better for me to just stick to updating to SM-G930A 7.0 via the guides posted, or is there a way for me to Flash the SM-930T 8.0 firmware? Thanks in advance.

Wow you guys really get screwed over there in the US with cell phones. It's a pain in the a** to do anything with your phones.
Anyway I'm guessing the phone was originally AT&T right? And now it's unlocked to any carrier.
If you just want to update the phone to the latest firmware then just flash AT&T Oreo. It won't affect the SIM it will still work as before.
If you want to flash any other firmware including T Mobile then you'll need to unlock the bootloader on the device and that's a whole different ball game. With plenty of guides on how to online.
Make sure you back up all the things you want to keep before flashing

Thanks for the reply! I appreciate the direction. You are right, US phones are a pain. And yes, the phone was originally an AT&T phone, but was unlocked.
As for unlocking the bootloader, I've found different sources that say that unlocking the bootloader on this particular phone is not possible with this particular phone. I did read something about an engineering bootloader being used to get around a locked bootloader for rooting. Could this be used for flashing as well?

That's not entirely true. Using Odin you can flash any USA firmware onto any other USA device, no bootloader unlocking required.
It's very common for people to flash G930U over their G930V/T/A/P devices to remove bloatware

It's unstable and only lets the device charge up to 80%, your best bet woulld just be a full flash with Odin
This guide is a bit dated but it's the best one out there. Just make sure you google the latest Odin and use all 4 firmware files when flashing https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin

Thanks for the reply! I had tried flashing the 8.0 G930T variant last night with the latest version of Odin and the PrinceComsy version and got a Model Mismatch error. I read that the modified Odin3 v3.13.1_3B_PatcheD would let me flash the firmware and ignore the Model Mismatch error. However, I didn't go through with it because I was not sure if I would brick my phone and instead erred on the side of caution and made my post here. Would I be safe to flash the files from SM-G930T_1_20180625111401_xf3965l42p_fac onto my current device?
If your firmware files are from a trusted source like sammobile, updato or samfirmtool then it should be fine
Odin3 v3.13.1_3B_PatcheD seems to have positive feedback here on XDA so should be fine too https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572

Greetings-
I apologize for jumping in an already created thread, but I think I am in the same situation, and like to verify with you both before I use the advice please. I have a SM-G930T that I just purchased, and really like to run a custom rom. But I understand I can not because I have Android 8 on it. I know how to use Odin, and have the latest version plus you guys talked about it here. I have also already downloaded the stock rom from sammobile site. What are my options? Is there a rom I can flash the phone with using Odin that would provide better performance, less G..bage, and more battery life? Is there a way for me to root the phone? I really need an app that requires the phone to be rooted.
Thanks

Ok, so flash any unbranded Stock Rom for your device using this version of Odin which has been specifically modified to flash US devices. https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572 PatcheD.zip is the file you want to download.
Then when you have checked the phone is working ok on undrnaded firmware you can go ahead and root the device using this method which is again for US Qualcomm devices. https://www.****************/2018/0...on-galaxy-s7-and-s7-edge-on-android-8-0-oreo/
Take you time and read instructions.

Can I get unbranded stock firmware from sammobile? I understand the generic meaning of it, but I need more information on how to get them and what I need to know to work with them.

If I understand it correctly there is no unbranded firmware for the US, its all network specific but you can flash unbranded UK firmware and it will work fine, UK BTU is the one you want from sammobile.
Load into the modified version of Odin and flash.
This is what I found, and downloading.

Yes that's the right one but like the beanvee and i have said there is a specific way to flash this stock then root the device.
You also need Samsung USB drivers installed so your pc can talk to your device, there's plenty of guides around how to flash with Odin and what you need to do beforehand, the only difference with you is the version of Odin your using and then the method of rooting afterwards.

Thanks. I have used Odin before, and I already downloaded the patchD version of Odin from the link. Thank you so much. I'll keep you posted on how it turns out. I still do not have a verified version of a custom recovery for this. Do you guys know of any? I found this link but the link to the suggested twrp does not work. I think it is this one. But I can not be sure. The original link points to a slightly different url.

Nope do not use that TWRP, it will flash TWRP but not boot it and you'll be stuck on Samsung logo forever.
There is still no way to unlock a Qualcomm snapdragon bootloader and i'm not sure anyone is working on it anymore.
All it means is you need to flash custom Roms via Odin or possibly the inbuilt S7 recovery, you just need to check the ROM is in a format which can be flashed that way.
With regards to finding a TWRP solution you'll have to do some serious searching on google and read everything.
There are already several de-bloated stock Roms on the forum if thats what you want to do. Root and custom recovery TWRP are two different things though, you get rooted so your good to go?

Yes root is my main goal, and you are right the debloated roms will work just fine. I can do w/o twrp. Just double checking here; since I am flashing the UK rom, and I believe one of the comments on this thread was how US images are locked tighter, would not I be able to find a UK version of TWRP for my phone? Just checking.

Now pull up a chair and listen closely.....99% of the American devices (including yours) have an extremely uncooperative Qualcommm Snapdragon cpu at it's heart and thus refuses point blank to play ball. The online community have done a fantastic job creating the modifications you are now using. The rest of the world (i'm happy to say) enjoy the S7 with an extreamly cooperative Exynos cpu at it's heart. It just loves to be fiddled with, it's a whore of a chip, constantly on the go with all kinds of neat tricks.
Anyhoo... my point is, the software has to be compatible with the hardware you catch my drift? All the cool little programs are written with a specific piece of hardware in mind, unfortunately for you guys Qualcomm is the ice queen.

Thank you so much. You guys are amazingly patient, and informative. Thank you for educating me, and helping me achieve my goal.
I have tried a few times but can not flash the files. I have attached screenshots, and followed the instructions here. Do you see anything I should be doing differently?
I initially thought the code came as one tar file, which I could flash, but it was a zip file, which I had to unpack.
