Possible to downgrade from Nougat? - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

I would love to try out Nougat so I can decide if it's worth it for me to switch from rooted U firmware. But if I decide I would rather have root, I'd like to be able to go back. I figure at this point somebody has tried it.
Edit: Searched a bunch of threads and found 2 people saying they've done it. Good enough proof for me.

I went from U to Tmo Nougat and hated it. It's not as smooth, I lost the built in white pages with spam telemarketer detection and the bloat.... all the bloat that couldn't be removed (thanks to that great pdp license activation not working). I am going to wait for the Nougat U firmware release.

I guess I'll just have to try and see if I like it. The only thing is that I HATE not having root. I preordered my S7E and had to wait months for root, that was actual hell lol.

ASUS cancelled 2.19.40.18 OTA

guys
http://www.asus.com/zentalk/forum.php?mod=redirect&goto=findpost&ptid=14836&pid=107979
asus said they cancelled this update due to unstable update...
1st i dont know what is unstable in this version[same as previous and new bug of call screen animation
2nd lol which update came without new bugs?
3rd they removed after they heard about unlocking bootloader..something fishy right :laugh:
they will probably patch the unlock method with the next update, gonna unlock the bootloader before updating to next update.

Maybe there just will be a check and it will abort if the BL is unlocked
But it should be easy to adapt these OTA updates to unlocked devices

Nothing they can do. As long as you don't flash an OTA or full stock build. They may have a way to patch it in their droidboot.

That's how it works with all custom work. Once you're off stock, you're going to have to wait for someone to post a safe update/install.
Rushing in and taking an OTA is a very common way of breaking your build. Like what we see with running an OTA while rooted. Any number of problems can come up.
They could patch any number of things that would give you a very bad day.
With the support we have here though, we'll probably have flashable, safe OTA zips within a few hours of an OTA being captured/downloaded.

well i am from sony device..they release main update of android..and 1 bug fix,thats all...so we dont care..and no need to worry about relocking issues..
this is the first asus device...man they releasing update for every 10days..i thought we could apply just like that..but since they didnt gave unlocked bootloader tool ,i got these doubt..
and thanks for info..
so i must wait for zips which is modified for unlocked bootloader[if they trying to relock]
I honestly doubt they're going to find a way to relock it with an update, but who knows what voodoo they may come up with.
Either way, we'll grab the updates and get them ready to be flashed quickly. It's a simple process.
I highly doubt he will do anything regarding unlocking/locking bootloader. because:
1. last year they released their official tool to unlock zenfone 4,5,6 bootloader after 3-4 months of release.
2. This year when they launched the zf2 in US they hold contest and developer events via xda. Now xda is a place where no one keeps their bootloader locked. so they knew exactly where they are releasing and advertising the product.
So I dont think they would even bother about this bootloader . Maybe it is an unstable build in terms of their quality test.
Dang, and my 551 (2/16GB) is still in transit.
Was browsing the forum and this thread - has 2.19 been captured and saved somewhere else, or was everyone just downloading off ASUS servers for this OTA (when forced)?
I don't know if I would want 2.19 yet. Maybe to keep on my PC until the right time. That is, if 2.20 comes out and the BL hole is plugged, and those who were on 2.19 (and took advantage of the bootloader unlocking) still got the update successfully - if either of those two outcomes are false, I wouldn't use it.

android is open source. and roms are not illegal. so why bother? i don't think asus is interested on ours bootloader plus, other zenfone's are already unlocked

Even if your phone gets here on a newer version (it won't), you could always downgrade everything and unlock from there. =)
Shakalaka has backups of everything going back to like version 2.12 or 2.13.

Problem is they can't support any ROM that isn't official on the zenfone. They'll pass you off. Like most manufacturers.
These are just official update links from Asus. Not backups. Asus can shut those down at any point. Not saying they will.

one more doubt..
i think 2.17 is stable build from asus without the android os drinking the battery
now i have unlocked the bootloader ,can i reflash the 2.17[asking since it doesnt have the things which enabled to unlock bootloader] ...or once unlocked,we can do anything like other brands phone?

I downloaded the appropriate OTA the other night, so if ASUS pulls the file, I still have it and can share it on Dropbox and/or Copy.
I get the phone today! So hopefully tonight I get the OTA up to 2.18 and then wait to see what upcoming 2.20 has to offer. If we can still unlock the BL with 2.20, I will let that OTA happen. Similarly if we find out that those who unlocked their bootloaders can't take the update (at that point I will cry a little, if there is no official way to unlock BL released with the update ).
If both scenarios above are false, then I will apply my downloaded 2.19, unlock the bootloader, then accept 2.20.
Best one could do eh?

I cannot imagine it would re-lock the bootloader. Should be able to downgrade, as long as you use the whole image and not just the OTA zip.
Now you got me wondering....

no i didnt mean it will relock,..
but the unlocked needed some file right..it modifies something right? ...and it is not present in old things..so can old fw run on unlocked bootloader? [or would it get bootloop or damage bootloader]

[Q] [Sprint users] Anyone on the LS997ZV5 update yet?

** Update**
Seems after the LS997ZV4 update was pulled off, they changed it to LS997ZV5 instead and just got it 12/26/16
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
I've been waiting for the OTA update on my phone, I have been manually checking for updates too but nothing happens!
The release date says 12/5/16 and I usually can get updates by manually checking with other android devices, not this time though..

rooting isn't important for me as it was before lollipop, there's not much bloatware on the V20 and ads are being taken care of with adguard.

ls9997zv4 update no longer shown on sprint website
I saw that update listed on Sprint's site last week and was also frustrated not to get it. It must have had an error because it has been pulled. We are lucky not to received flawed firmware.
They probably pulled it to fix the exploit they have found for rooting the phone.

I just got updated to LS997ZV5 Dec 1 Security patches, fixed an issue with loud speaker and stuff I don't remember.
I got it on 12/24. I had to click "check for update" quite a few times for it to show up.
Same here. I hoped it would have fixed the speaker distortion problem. But it did nothing for me.

I read everything I could find about rooting this thing and read all the comments that the bootloader exploit was fix with the December patch.but nothing convinced me not to...Im a old Samsung guy, Note 2, 3 & 4 so rooting without having Odin to back me up was a tad daunting as well as having to remember how to use ADB....I took a chance and it worked......I got the sd corrupt error ( no biggie, I had backups) and battery drain is kinda high ( no sprint custom kernels yet) ....of course it not being a stock sprint rom things like wifi calling, sprint zone and voicemail are missing ( but Team Dev now hows a stock rooted sprint rom out, Ill try that in the am) everything is running just fine...installed all my apps, made a titanium backup and a twrp backup.....

G935U Nougat

Hi All,
I'm a little confused as to where us U firmware users stand with Nougat. I've seen differing reports of what the known plan is with this. I believe some are saying we're waiting for Verizon to release it to the 935u, otherwise I'm reading that we're on a quarterly update schedule and won't be seeing anything until April.
I bought my 935V from VZW and flashed over to unrooted U firmware - actually by using the normal flash method and then doing a firmware restore from verizon's utility to get full unroot. Not exactly a typical method, but it gave me peace of mind knowing everything is completely stock U.
Everything is running great so I'm not in urgent need of an update for any reason, but would like to see some new features.
Lemme know if anyone has any clues here as for what to expect. Thanks in advance!
Not exactly sure what you mean by going full "unroot".. unless you ment, you wanted the U firmware for a smoother "root" can you please clarify bubby?

Good to know. Thanks.
I had to root in order to flash U FW, but the root process we have for GS7 is really process heavy and battery draining. I wanted an unrooted version of the U firmware with no bullsh*t and good battery life so I unrooted and restored using the software tool.

Ah Gotcha, sorry I misunderstood the op. Maybe give the T or V carrier FW a spin till U gets released? I haven't upgraded yet but am tempted. Been using stang 5.0 rom and been pretty impressed. I'd say I would recommend it even with the faults of the eng boot.
I also believe I seen a "no root no bull**** playstore Nougat rom" by jkruse, or something to that effect. If that's something your into
Lots of cry babies over in the Samsung forums. I can see why everyone is so upset but Samsung never promised faster updates for unlocked variants over carrier models. I'm content waiting at least until April for the nougat release of the 935u. Screw Verizon bloat. It's not worth putting up with it for Nougat.
There are some articles with Samsung's new commitment for monthly security updates on unlocked devices. This should mean that the 935U will get Nougat this month with March security update.

Yes i have the original UDP and the tethering option works. How ever i cant get the verizon video calling to work??
So from what I'm getting, to install (if I'm on Verizon Nougat), flash Unlocked 6.0 first, then smart switch to 7.0? Also, I read that someone had been having issues with using LTE while in a phone call, can anyone confirm? And what happened to all the other fix files, since I remember the first time flashing the unlocked software required more subsequent flashes as well.

Nope don't take it...best thing to do is to wait until you find out whether or not you can Odin back to old firmware...if you one of those who like to mod I would seriously wait until you find out more about it...nothing good ever comes from those who jump the gun...he'll were lucky enough to have root and modifications despite our locked bootloader.

Can i downgrade to nougat from Oreo with bootloader 3

I was on nougat until the other night i believe my dog stepped on the update button because it comes up all the time and i usually ignore it. I want to get back to nougat(phone is unuseable on oreo)and root so this never happens again. I just paid it off also. Please give me a hand.
Edit:bootloader v3
Nope it's patched might as well use pie beta now
No root and no downgrade. Have to get another rev 2 since if you want root again or wait to see if it ever becomes available on rev or higher
Sucks so bad. Ive held off that update since i bought it and woke up in the morning to 8.0. Just paid it off also. Now its not even worth that much. Definitely my last flagship and last Samsung.
The guys from one of the safestrap root threads are saying I can get back to nougat as long as I am not past v5 bootloader. Have you heard anything about this?

If you are a regular s8 no. The combination file is a nougat system but is not functional as a everyday driver. This device prevents downgrading so yes technically if you flash the combination. It is a 7.0 base but no apps full of bugs. Heat. Crappy battery. No play store no nothing. Combination files are Samsung test imgs again not usable systems. So whoever is telling you this they can tell me too cause unless they said the same as this they are rolling off crap.
If you own a s8+ you posted in the wrong section and yes you can flash the rooted system. Or whatever they use til at least rev 3 bootloader.
Yes I was in the wrong forum. Thanks for the info. I used chat alot with ya on the telegram s8+ channel. Did you ever root yours? What allows the S8+ to be able to go back to nougat using the safestrap/samfail method? I was under the impression the phones were very similar hardware/software wise. Im just happy I can go back to nougat. I hate oreo.

Yeah my s8 had been rooted since like day 5 of having it. They either skipped or just messed up on patching the +. Past to me shows they don't patch the best model. I've seen it with several lgs. Samsung's. The plus models always get more attention.
Yeah I gave up that group, the management and I didn't see eye to eye. Now I run my own ????
Can you pm me your telegram? I'd love to be a part of one again. Thanks again for all your replies.
