Is it safe to update a rooted tablet?

Hi everyone
I'm a proud owner of a Galaxy Tablet. Recently I got a message in my settings that there is an update available. This is my first tablet so I'm not veru expérienced. My tablet is rooted. It crashed a couple of times but all in all seems to be working. My question is if it's safe to update. I read in the forums about phones being bricked and other problems with updating rooted phones and tablets. Is there anything I should do before installing the update to make sure it works?
Any advice is appriciated. Cheers.

In general, I would recommend against that.
At least you will lose root, or you may semi-brick your tablet.

Rather than update, I would suggest flashing to a stock Gingerbread ROM. It will be almost the same as an update, but you will still be rooted. Or you can go with a custom GB ROM like Overcome or BOCA. If you want to get the newest, I'd go with CM9/ICS. This gives you the brand new Ice Cream Sandwich. I'm enjoying it very much on my tab. I was hesitant because the theme engine is still not there, but someone suggested to me GO Launcher EX, and that thing works like a charm on CM9.

Was just reading about SuperSU that just came out and it can trick your device into thinking its unrooted, ie for updating stock firmware but bigz is right, there's a lot to be had with custom ROM's
Here's the link for SuperSU though

Thank you very much people for your prompt replys. I only rooted my tablet to have an access to ad hoc wifis. I'm certainly enjoying Titanium Back Up and things like that. So I would like to stay rooted. Being inexperienced I sort of was more inclined to unroot it with a superoneclick then update it and then root it all over again.
Is it possible?
And I'm only trying to do it because I believe that the company's update is always the best. (Funny attitude for a rooted user, but I only understood it recently). Because normaly they do everything for you. So if I go with IT free spirited people then I will have a lot more questions.
* Are custom roms as stable and relyable as the official updates? Far be it from me to doubt the expertise of the guys who write them, I'm just really new to it.
* I understood from one of the posts that it might be even safer to flash a new ROM rather than do an official update. How does that work? I would like to understand before committing.
* And if I do a full back up with CWM (ROM included), does bricking bother me? I'm not very sure what bricking a tablet is.
I'll stop here with the questions not to be too heavey. My tablet: Samsung Galaxy P7310 8.9 WiFi only Honeycomb 3.1
Thanks in advance.!

Well, you are in wrong forum then.

what your means by gtab7+ is suck as crap ...?can you just explain,don't mind i am also a samsung galaxy tab 7" user.

There is no issue in un rooting your device and then upgrading it by keis and then rooting again and restoring your apps and data, Some apps may be incompatible with new version but you can check this in the market.
Just did this last week on my son's tab.
If you are running a custom rom then having a nandroid backup by cwm is advisable and if you don't like the upgrade then restore
If you run stock then you should upgrade via keis because you will get enhancements
Hope this helps. There are sticky guides on how to do this so would not worry as long v as you follow the instructions your fine.

Request Rom Manager vs Boot Loader Clarification

Not a Dev, but not a Noob, either. Formerly had a SGH-i897 Galaxy S for 3 years and flashed like crazy on it, while transitioning from Eclair to Froyo to Gingerbread to ICS to Jellybean, mostly using the fine offerings from the AOCP Collective folks. While familiar with Odin, CWM was my usual go-to utility.
Upgraded recently to a SGH-i337 Galaxy S4. Must have owned it for two, maybe three hours, before I rooted it with MotoChopper. This allowed me to re-install Titanium Backup. I left it as merely rooted, while I read up on CWM and some new-fangled thing called TWRP, which I wanted to get installed before casting about for a new ROM. (At the time, AOCP did not have an offering here, or it would have been a no-brainer for me.)
One morning, I turned on the phone and noticed it was doing an OTA update. . . . . . . . .
Mildly curious, I logged onto XDA to read what the community thought about the update, only to discover that I had missed all the dire warnings by a day and my (now) version I337UCUAMF3 ROM had it's boot-loaders locked from a blown Q-Fuse, courtesy of Samsung and AT&T.
Took me a week before I found the rooting solution from jortex, but thankfully, I'm now rooted again.
This background now leads to my questions:
I have ROM Manager Premium (from previous purchase) but have not installed it.
I was aware on my previous SGH-i897 that mixing the Gingerbread and Jellybean boot loaders was like, a Bad Thing when flashing ROMs and would promptly brick the phone.
Does CWM require the ability to load from a boot loader?
I know it creates an update.zip file to restore the original ROM, and usually does so by using whatever ROM is installed at the time.
So wouldn't it just create an update based on the I337UCUAMF3 ROM?
Even if I can't flash new ROMs (unless or until somebody comes up with a Q-Fuse Fix) couldn't I at least have all the recovery and .zip flashing of apps and cache clearing menu choices available to me from CWM?
Or would the act of just installing CWM on a I337UCUAMF3 ROM immediately brick my phone?
In Other Words, how close can I dance to the water's edge?
Been to the ROM Manager web site and they claim I can do any thing at any time.
(Easy for them to say: It ain't THEIR phones!)
Been searching these threads and can't come up with anything explicitly stating yea or nay.
So far, I have been happy enough with the TW stock ROM, but I always felt better being able to boot to recovery to fix things, on those few occasions I got just a leeeeeetle too close to the Bleeding Edge!
What is the consensus out there?
Will CWM 6.0.3.6 bork a I337UCUAMF3? Yes or no?
Would appreciate any thoughts that might enlighten me! :fingers-crossed:

It sure could brick the phone, the only thing you can do at the moment is root. I have seen a couple people try running a recovery on it, and it required a jtag service to restore the device.
Be careful.

This phone is far different from the Captivate. There is no flashing anything on MF3. Basically you are waiting for a work around if that is even possible.

New to S4

How's it going? I am upgrading to the S4 coming from the e4gt on Thursday. I've flashed just about everything there is for the e4gt, but would like to know what is recommended for starting out with this phone. What recovery do you recommend? I've downloaded the cf autoroot which I plan on using, and also the cwm jfltespr 6.0.3.6. Is this the best route for getting started? Thanks in advance.

Welcome over bt.
If you're going to stay on 4.2 then TWRP 2..5.0.2 has proven best for me and most others. TWRP-Recovery-jfltespr-2.5.0.2
If you're going to jump in to 4.3 (and I suspect you will) then use Philz CWM based recovery. philz_touch_5.18.2-jfltespr.tar
Just know that if you take the OTA or Odin 4.3 there is NO going back to 4.2 because of the Knox bootloader.
You can however run 4.3 on 4.2 firmware (non Knox tripped bootloader).
Many of the usual Sammy stuff caveats are the same. biggest difference is that Kernels are seperated from Recoveries. Making it easy to mix and match.
Flashing is a breeze, developers here are great - many came from the e4gt and S3. Same with the contributors and others.
Take some time to read through the posts and you'll soon get a good handle on it.
Have fun!

Hey, i remember you. It's great to see you here. How do I avoid the ota? Can I freeze system updates in tb or for toolbox? Also, what rom do you recommend that I try first? I was looking at the carbon rom, but will try 4.2 first because it looks like they have the save data issues on 4.3 like the e4gt. I will miss all the guys on project x.

If you install a custom recovery and kernel you won't be able to take the OTA - it may download but shouldn't install. I use TB to freeze Sprint Installer and Sprint Zone. Sprint Installer is a really sneaky app - it goes out and grabs all their crapware and just loads it up!.
I'd recommend Any of the 4.2 ROMs if you'd like to mess around - Sac, Unknownforce, Negamann's and of course rujelus22's.
For 4.3 I'd say give those guys a go too; just be sure to do it without tripping the Knox counter - using custom recovery and flashing ROM that has the knox bootloader removed.
For CM/AOSP type there are some pretty good ones too.Carbon, Sniper and Garwynn have some builds up. I like to try them but I'm a TW guy - I have to have everything working flawlessly for business so even small things like no 4G, no sms or the like make using them for my daily driver still out of the question for now.

as @BIGSAMDA1ST said, there is that possibility. Really depends on the supplier and how deep their inventory is.
If is on 4.2, after initial setup it will surely try and update to 4.3 if you let it - I wouldn't. But that's just me. I'd keep it 4.2 and go the 'non-knox' route to 4.3.

Welcome!
I just got mine on Monday Pre Balck Friday Sale, been on E4GT bricked 3, 4th the power button broke and the E4GT was BO so the bumped me to GS3 was rooted running Cyan 11 4.4 kitkat, PA Gapps, Xposed 128 DPI then the Pre Sale .96 cent's upgraded to this GS4. Monday got it and a hour later the 4.3 OTA was pushed to the phone.
I do have to say this is a Big Learning Curve because a lot of the customization i was used to do on my phone is already stock on this phone.
Been researching trying to figure what exactly to do but also been running tests to see what improvements Sprint and or the phone has made for me. I agree with Leaderbuilder " I have to have everything working flawlessly for business so even small things like no 4G, no sms or the like make using them for my daily driver still out of the question for now".
Everything has seemed to be running great my wife upgraded from Galaxy S "GB" love ginger just not as a OP. Spending a lot of time finding how things work for her and have yet to set my phone up or let it settle in. I say all this to say "what I've read" in all different posts is there is possibly 1 stable 4.4 rom and just now trying to compare the benefit for me rooting. I know removing bloatware but it doesn't seem to be messing the phone up like it did on E4GT, battery life? What I've seen this is pretty good. So take your time get your phone and get used to it I think those of us who came from E4GT was used to having a "fairly good" phone and rooting to make it better however this seems to be at a different level.

I just moved from the Epic 4G to an S4. Still really missing my slide-out keyboard...
I bought my S4 a week ago and it came with 4.2.2. I had NO clue about the Knox BS, and doing a quick Google for 4.3 issues did not bring it up, so I took the OTA update. BIG mistake... Especially since I need to root to run ARLiberator.
Thankfully, my Sprint dealer is great, and after finding they could not roll it back, gave me a direct exchange to a new S4 with 4.2.2. If they would not have done that, I would have exchanged it for a white one to get back to 4.2.2.
Sooo, to sum it up, as of yesterday, it was possible to still get an S4 with 4.2.2 without Knox on it.

Chalk it up to me being an old 48 gray haired (although consider myself pretty good searcher) What exactly is Knox and why/not want or want it?What is the issue with taking the OTA update? Layman's terms? My sprint store has really cool tech's but they know nothing about rooting and all different issues. Always like playing with my phone for a bit and never get pissed if I get an issue they can't resolve.
Should I not have done the OTA update? I'm trying to determine if I actually want to root or not because things have seemed good so far.
Main 4.4 item i wanted was "OK Google" but I've got that on my stock phone, sure 128 dpi would be great but if it really worth it for me? I'm still out to lunch on that one.

The OTA update installs the Knox boot loader which cannot be rolled back. Once on it, you are on it for good, at least at present.
Knox adds a tattle-tale, so that if you root in the conventional, "fully rooted" manner, install a custom recovery, rom, or kernel, it will trip a flag, titled "Knox Warranty Void" which cannot, at present, be reset. which also breaks certain functionality in the phone. If you don't care about tripping this flag, it looks like you can still mod your phone as before.
There is a way to partially root in spite of Knox, without tripping the flag, but this method may open your phone up in ways you don't want to do. This is still under investigation.
Personally, I did not want a non-resetable flag telling Sprint/Samsung that I had modded my phone... That in itself was enough to make me return the phone.

Thank you for explaining now you have given me more to think about. Why do they care since warranties still cover rooting? Also makes me have something else to add to the puzzle do I root or not. Most things I was rooting for are now stock so I will continue to think about now knowing about the Knox.

Hello BTVOLTA...looking fwd to being here as well. Coming from the E4GT myself this evening and am looking forward to the stuff this thing has the ability to do:thumbup:

Well the knox bootloader is big if you are worried about warranty issus and if may need to run 4.2 ROMs.
If you don't think you ever will have either of those situations then that shouldn't matter.
Knox also does have some cool stuff for the corporate world - high security container for applications etc. It's essentially a secure 'sandbox'. I think you'll find many more corps. insisting on an using it. I know my brothers company gave him an S4 with knox for just that reason - secure email/CRM container and connection. This guy had the need too.
But for me I really am pissed that, if needed, I could not set my device to factory original.
Just one more thing an entity will use to keep from supporting a hardware problem they should own by blaming me.
I've had phones with bad radios (GPS part) that needed warranty replacement and one time was told no because I had a custom ROM and the problem was my ROM or my fault for 'destroying' the chip. I promplty went back around the corner flashed a stock .tar and walked back in and proved it to be the hardware.
All that being said this is so far the best phone I've had. And the developers and support folks here are great.
Welcom over y'all and have some fun.

Just got mine and I guess while I was looking foe a case they pushed the update while setting up my s4.
Any advice on what to do?

Depending on the inventory your new one may come with MF9. If so you can just use cf-autoroot to root install a custom recovery and go from there. There is a thread on how to update that firmware (modem and radio) without tripping the knox counter.
To keep it from updating don't take any 'Sprint Firmware updates' during install. You can root right away and then use Titanium to freez the sprint installer and sprint zone to keep the update at bay.
If it comes with MJA you can still root and then install custom recovery. You will just not be able to run a 4.2 ROM stock (using Odin).

Yeah thats the issue part says dont care othet says dont need security issue but its nice to be safe amd secure. Bricked 3 E4GT andb4th power button broke but all covered by insurance when they upgraded me to GS3 and then I needed a new phone and got the Gs4.
My 3 was running Cyan 11 w/4.4 kitkat and Xposed 128 dpi. I have almost everything I was used to with root with this stock except the 128 dpi so Im trying to figure if I just need to play it safe for a while or not.
I'm irritated by the play store every time I try to install with it pulling 1 of 3 error codes ever since upgraded to 4.3 so part of me wants to just root to 4.4 since I know how it runs but Ive only found 1 stable 4.4 available and not too familiar of roms since my experience is from E4GT and Gs3 days.
My first thoughts are if I know I may have issues and create more issues with my phone with Knox then why even bother?
Last clarification if I root Knox then acts like the old odin counter and or it also will keep me from flashing unroot back to stock? Kinda if can't reboot back to stock then if I softbrick and need help im on my own where as in past I still got help from sprint tech support and insurance because they couldn't prove I rooted an csused the issue.
Knox makes it permanent like water damage sticker with iOs?

I was all over it, made sure they didn't push the update. I now have it frozen, and I flashed beanstalk. It's running great so far. It seems though that none of the nice features that come with this phone are on this ROM. Next I will look to flash another kernel and then comadose. BTW, the recovery I installed B is Philz. It appears that if you want to use some of the nice stock options, probably need flash a TW ROM.

Rooted 4.2.2 MDL wanting to get OTA 4.3

I am on 4.2.2 MDL and have read over these forums alot to look for my issue but i have not come across exactly what to do.
I want to get the latest OTA which is 4.3
I have the OTA for MF3 I think it is? Its the one that locked the bootloader down tight and no one wants, since no Custom ROMs
I do not want any custom roms like CWM (although I loved it on older phones) I don't want to lose the functionality I bought this phone for.
When i tried to OTA to the locked bootloader version it fails at 32% or so.
The Phone is rooted.. and busybox installed. I mostly use this just for Titanium backup my apps.
So here is my question.
I want to get to the latest version available.
I have attached a screenshot of my about, if there is any other information required i'll be happy to provide!

Please don't upgrade and loose your MDL firmware, you'll regret it. You have many options for great TW roms, like GoldenEye that will offer a much better 4.3 experience versus the AT&T stock 4.3. Your bootloader was NEVER unlocked. The MDL firmware just allowed us to use Loki, which was an easy way around it. AT&T patched this with MF3 firmware in July. They do have safestrap for MF3, but its not CWM.
What exactly can't your phone do with MDL firmware and a custom rom? I don't get that? If you upgrade OTA, you will have Samsung's new knox crap, which if you ever do anything to your phone, it will set it to 0x1 and void your warranty.

I was reading you lose the Motions and Gestures with custom ROMS, I know CWM does not support that.
I do like that feature and I do use them on my S4.
I wanted to get to 4.3 to support the Galaxy Gear eventually.
Among I also do enjoy being uptodate
I understand completely how most of you hardcore modders and rom guys love your roms.
There were only slightly features in CWM I loved, which I can live without. But to completely knock out some of the biggest features of the S4 (the motions and gestures etc) Seems a waste of even buying this device in the first place.
Sure it has great hardware and alot would argue that.. but you can buy other devices with awesome hardware.
If you can point me to a custom rom for 4.3 (that will have the full support for galaxy gear) and it will support motions and gestures and lose 0 functionality I currently have, That'd be great. But I did not see that anywhere yet.

I am not sure if GoldenEye supports the Galaxy Gear, but try out that rom out first. It's based entirely off the Internation S4's 4.3 firmware and it offers a lot more. Its optimized for AT&T, and includes all the motions and gestures. You loose the motions and gestures with a non Touch-Wiz rom, like AOKP for example. But that's whats so great about custom roms. When you get bored of touch-wiz, you can flash a pure google experience and vice versa.
Maybe this is just me, but in the beginning, before we had custom recovery for MDL, I found the AT&T stock experience to be absolutely awful. By far the worst Samsung stock experience I have ever had. I also can't stand how low Samsung puts the headphone volume, along with those annoying volume nags.
Try GoldenEye out and see how you like it. If you don't, then upgrade.

I've always loved Samsungs TouchWiz, they have been my favorite UI, Galaxy S is the best imo.
Can you link me to the official Goldeneye and everything I need?
I'd appreciate that alot.
I use Titanium Backup, so app restore shouldn't be a problem and I've done it before so im ok with trying it out.
If there is any tips or tricks with restoring your apps and data switching ROMs, i'd appreciate that bit of info too.
Always feared to post on these forums since alot of people in the past get angry and talk mean to people that don't know the whole book on this

You really need to search and read up on a lot if you are unfamiliar with rooting and flashing custom roms. If you don't know what you are doing, then you WILL brick your device. If you brick your device to the point where you cannot fix it, you are SOL. Samsung will know you modified the software and your warranty will be void.
But you should start here:
http://forum.xda-developers.com/showthread.php?t=2297033
This tool will do it all for you. You must be on MDL firmware for this to work. Once you run that program, you'll have CWM (Auto Loki'd). Then follow the directions in the rom's OP.
GoldenEye (Based on Samsung's International 4.3 stock)
http://forum.xda-developers.com/showthread.php?t=2313469
Or if you want the AT&T 4.3 stock rom, iB4StiD also has a rom for that, MDOB
http://forum.xda-developers.com/showthread.php?t=2280556
Either way, you have A LOT of reading to do. I was once new and a complete air head on how to root, flash roms, and what not. The people on this site can be ignorant jerks who don't like noobs, like yourself. You are expected to do everything on your own, and no one will hold your hand. I usually don't provide what I did above, but I would hate to see you foolishly upgrade. Once you do, you are stuck. Good Luck.

I guess I was not clear enough my apologies.
I have flashed custom recovery and roms plenty of times on my older phones.
It did take a bit of reading but once you understand what limitations your device has (what will brick it etc) its not so bad
I just wanted the "proper" links from you so I start off right, I can definately handle it from here.
Quick question when i attempted to update did it somehow maybe give me KNOX?

I guess I was not clear enough my apologies.
I have flashed custom recovery and roms plenty of times on my older phones.
It did take a bit of reading but once you understand what limitations your device has (what will brick it etc) its not so bad
I just wanted the "proper" links from you so I start off right, I can definately handle it from here.
Quick question when i attempted to update did it somehow maybe give me KNOX?

If you updated to anything, the links I provided you with will completely BRICK your phone. Your current firmware MUST BE MDL to use the links I gave you. If you are on MF3, DO NOT, I REPEAT, DO NOT USE THE LINKS ABOVE.
---------- Post added at 08:27 PM ---------- Previous post was at 08:26 PM ----------
I am not sure if it gave you KNOX, since the update failed. I doubt it. But I would restore to stock MDL, then use the tool I provided you with.

lol its ok I know what im doing I know that MDL is required.
Clearly in my screenshot im on MDL... i was asking about KNOX randomly being on my phone since I thought it only came with one of the OTA updates?
I am on MDL and if you double check my screenshot does everything look ok to do the flash?
Again just wanted to double check about the knox thing.

Yeah I see your screen shot. You look good from there. However, I do not know the repercussions your failed update had, if any? I would say you are probably fine. But I am no developer, or expert.
What you need to do is restore your phone to pure MDL stock via odin. Take your SIM card OUT, so that once the phone is restored it doesn't start updating. You'll then enable USB debugging and use the tool I provided you with in the other post. After that, its cake.

Ah darn... From the oneclick post thats a 1.6GB file lol will take me a couple of hours to download.
But if you insist I will do it. I do believe in starting clean is always a good idea too.

There are other mirrors for the MDL file, you just have to look. Let me see if I can find one.
Try the one in this thread.
http://forum.xda-developers.com/showthread.php?t=2563533
The one I suggest isn't recommended apparently. You can try it, but I don't know. Apparently that site isn't good for stock roms. I don't know.

Alright im just downloading the one from the oneclick post, it seems to be downloading fine so i will stick with that for now.
So everything will work fine correct? Including the IR Blaster? I do love remote controlling my TV!
I use samsungs watch on app

That I can confirm. I am using GoldenEye and love my remote

Did you successfully restore stock MDL and use that tool I provide you with? Hopefully everything went well.

Yes everything is fine.
That file they had was I think the orginal stock so not MDL but worked fine.
Its been working great, although the Messaging app and Contacts background is completely black.
on the stock S4 it wasnt... i cant for the life of me remember what it looked like, But I have been looking for a way to change it and there doesnt seem to be (I thought it was a phone setting, like light to dark, vice versa)
So far thats the only complaint, pretty big one too, cause i dont like solid black lol

Oh so you flashed the ADMB firmware? Yeah, loki works with that too. Buy boy is that firmware terrible. So have you loaded GoldenEye up yet?

Of course, Been loaded since last night

See??? Wasn't it worth it? Hopefully all your features are there? I also recommending flashing the volume mod he lists.

Sorry for this question but I need to confirm my suspicion...The only way to get custom roms right now is with MDL (actually the one I have). Once you go MF3, MJ6,MJ9 or MK2 there is no way to go back??

"New" comer here, I need some help please

Hey guys, I have been out of the android world for a couple of years, I would appreciate some guidance.
I I'm currently living in US
T-mobil
Model number: SM-G935T
Android version: 6.0.1
Updated right now
So my question is, since I don't have any backup or anything, can someone provide me with the steps to get me started? Like what post to root it on this specific carrier and how everything? please
Thanks

Of course we can get your started but see
But first you must answer us these question three.
Why do you want root?
Do you have a computer? (This is a must for root.)
Are you ready to be disappointed?

https://forum.xda-developers.com/tmobile-s7-edge/how-to/how-to-root-s7-edge-t3410470
follow this (use odin to flash rooted kernel) ......you should search before posting things like this.....google is your friend bro.
GOOD LUCK - BTW use flash fire app in play store to make backups and flash roms

Okay okay.
A quick glance at T-Mobile Samsung Galaxy S7 Edge Guides, News, & Discussion would have led you to the "How to root the S7 EDGE" thread.
I'd take a look in there if I were you.

Well while I was waiting I just rooted it. So what do you think that would be the next step towards installing a rom? To answer your survey questions :laugh: :
1- Because a phone without being rooted is like a bird without wins.
2- I do
3- Oh well... tell me more

EDIT: I just checked and the root didn't go through... even though ODIN said it was successful

Well then.
Rooting the phone (as I'm sure you had already found out) was fairly easy.
BUT... since we do not have an unlocked bootloader then we cannot have any custom recovery. Which means we can only (for now) use adb and Fireflash to flash any custom firmwares. And while we're on the subject of that... there is only one custom rom. Well... technically there are two but only one for you since you updated to the latest firmware.
Echoe ROM which was updated (ummm...) September 9th (not including the Verizon version which might work but with no promises)
Tekxv2 which was updated back in July. Unfortunately, that is flashed by adb (computer required) and only supports G935TUVS3APD8 which is... pretty old.
Things that you may notice with root.
Battery life may be shorter.
Strange icons on your status bar.
Might start to have random reboots for absolutely no reason.
Can't use Samsung Pay and some other apps.
Phone might be laggy.
Phone might feel hot.
Some of those can be resolved by flashing the only custom rom that we have (Echoe ROM... which is a rather nice rom) but it's not "there" yet.
Or you can use the guide in my signature to resolve issues like the lag and the strange icons. Yet even after the "fix" you might still experience both again from time to time.
You might even have the IMS force close issue which I used to get about once a month. It would piss me off because no sooner that you click the button, it'll pop up again and you don't have time to do anything. You're pretty much forced to reflash stock, wipe, re-root, restore a latest backup... which can take hours and is rather inconvenient if it happens to you while you're at work like it always seemed to happen for me.
SO...
All in all... root is okay. It's better than nothing I suppose. But until we get more developer support for this phone then in my opinion it's kinda pointless in my opinion.
Too many drawbacks. I eventually unrooted two weeks ago and I love my phone now. I'm using the heck out of Samsung Pay especially since their promotions are pretty nice right now! Plus a few members are testing the Nouget update which probably won't be getting root at all since rooting requires an engineering kernel which we don't have and might not get. Or an unlocked bootloader which we've pretty much given up on.
A lot of members that are testing the Nouget beta firmware are extremely satisfied with it so if we can't root Nouget then having a rooted S7 will probably fade away as more people update to Android 7+. That's where I see this going anyway.

So for what I understood the dev support for this phone is very limited... I know the issues I may encounter, I had them with the galaxy note. but any way... If something I'll unroot it but I want to try it out Thank for you time. I've rooted it.
EDIT: Damn... I really don't like the visual style of Echoe... is that one the only one I can flash??

How are you doing with the ads? Like youtube, pandora, spotify? I just installed xposed and the phone feels very hot, and If I unroot it (which I'm thinking to do) I won't be able to get things without ads (I know about vpns and browsers). Also how can I install teaks for apps? Installing apks from pages that promise you this and you have to log in is very untruthful. Any suggestions to all this?

I just put up with them.
In all reality, I don't use my phone for the purposes that require my viewing of ads to begin with.
Sure when I was rooted I had adblocker. But honestly, I had completely forgotten all about that benefit of being rooted until now.
I suppose if you absolutely need to be rid of ads then by all means, retain root. However ads don't effect my daily use one bit.

I just flash the appropriate firmware that you had prior to rooting with ODIN.
Never had any issues. Which "guide" are you referring to?

You're probably trying to flash a firmware with a V3 bootloader over G935TTMB4APK1.
If you were seriously following that (outdated) guide step by step then you tried flashing TMB_G935TUVU3APG1.zip over a PK1 firmware. Yeah... that doesn't work.
Download the latest firmware from sammmobile.
https://www.sammobile.com/firmwares/database/SM-G935T/
Try it again.
IF that doesn't work... try using Smart Switch.
I haven't done it before but I think it's the Emergency Software Recovery and Initialization.

You have no idea the help you gave me. I went to sammobil before but since it said that the download speed was too slow, I didn't do it through that page. Now I did it and it's working fine thanks bro.
But when I start it, it says: custom in the log in, how can I totally put it original?

You should flash everything.
BL= Bootloader (which should be V4 since you updated to the latest firmware already. Anything less than V4 will fail.)
AP= Is for System, Cache, kernel, etc.
CP= Is for modems
CSC is for your HOME_CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 file.
Important! If you use the CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 (doesn't have the word "HOME" in the name) then it'll wipe your phone!
If your phone still says "CUSTOM" on it then make sure that reboot and check again. If it still says custom then make sure that you don't still have the engineering kernel. Re-flash the AP files again if so. It shouldn't though if it's 100% stock. Also note if you saw the unlocked padlock on the S7 Edge splash screen (before the bootanimation).
Good luck and happy New Year.
