[Q] No root with ANK1 - is it safe to rollback to previous firmware?

I'm just wondering if it's safe to rollback the firmware on my Galaxy Tab S 10.5" to the previous one or if it causes some sort of conflict.
I want to do so because I've just installed the most recent one (T800ODD1ANK1 - India) and I can't root it using Cf-Autoroot posted here.
Thanks!

What happens when you try to root it?

Nothing. I did it with Odin and it just reboots to the same old unrooted tablet. All is working fine as usual, but no root.

What botters me the most is that I had Xposed framework installed but now it has no functionality and all the modules I had installed don't work. I would install the previous firmware but I'm afraid of breaking something, with installing older software on top of newer one.

I was able to root the US version of that ROM (T800XXU1ANK1) using CF Auto Root from Chainfire:
http://download.chainfire.eu/473/CF...uto-Root-chagallwifi-chagallwifixx-smt800.zip
Perhaps give that a shot???

I will but the India version has a more recent changelist (which was the reason why I chose to install it).
Thanks in advance.

As I predicted, since the changelist is different (your version has the same as the older one I had, with functioning root, but not with this one), no root.
Does anyone know if it is safe to install a previous version of the software? Like, for example, Cellular South ANK1 (with an older changelist).
Thanks.

I'm having the same issue as the original poster. It says I am rooted, but I'm not because root checker just keeps spinning and there isn't a SU# icon in my apps. I've done this with Odin about a million times before, for some reason on my new T800 (after I updated the software), it doesn't work.
Am I missing a step because I have the same version you have? Extract the file. Load the md5 file into AP. Hit Start. Wait for it to reboot. Right?
Yea root isn't working for me with T800XXU1ANK1. =(

Im assuming you ran Super SU and updated the binaries or whatever it asks, or updated the app in playstore?
Ive done nothing different and root works fine.

I was thinking about another root alternative. I was thinking about downloading the supersu zip and save it to the device or sd card. Then flash twrp recovery with odin, then boot into recovery and flash the supersu zip to get root? Could that work as an alternative since it flashes root in the process?

I just rolled back to T800XXU1ANJ6 and I am rooted.

I just bought a Tab S, and I can't seem to find an answer to a question that relates to this thread. Is there any advantage to updating before rooting?
I can't decide if I should root it now or update the software, and then root. After searching some, it appears that it doesn't matter whether I upgrade or not, but I can't seem to find if there is any advantage to updating it then rooting. Like, is it easier to get the latest firmware that way?

If i am correct, There should be stock custom roms available that are prerooted so you can flash over. As for an ota update, that is faster than being rooted then flashing lollipop rom.
Anyway we have a lollipop rom already built. Its smooth and most things are working. Its really cool and id rather use this than waiting for samsung to get the latest update out. Do you have the 10.5 in or 8.4 inch?

I have the wifi 10.5 inch.
So, you are saying update OTA then root, unless I want to jump to Lollipop (which I do), which in that case it doesn't matter so I should just root and flash a lollipop rom?
Thanks for helping me out.

Up to you If you want to jump to lollipop/CM12, just run flash Cfautoroot( with odin to root) then install twrp and flash the lollipop rom. There is a thread for cm12/lollipop in the development tab s section.
But wait! Rooting trips knox with voids your warranty. Same users has reported getting service from samsung for free of charge from defective units and some had to pay to get defective parts replaced by samsung. 50/50 chance. I took the risk and havent got a hardbrick or anything yet.

Thank you for the heads-up. I've rooted all 6 of my android phones that I've had, so I'm not too worried about voiding the watrranty. Judging by your reply it sounds like there are a lot of lemons out there for this device. Mine seems to be running okay, but I just can't take all the lag that I assume comes from TW and bloatware. My HTC One M8 with Lollipop seems faster and smoother than my Tab S at stock. Although after typing the last sentence, I put Nova on there and sped up all the animations and it is definitely light years faster than my One M8 now.

I think the answer to the original post is that the Su binary was installed, but the op didn't download then update Super su after rooting. You wont get full root until you do as there is no app to handle root requests.

[Q] Galaxy Tab S 10.5 sm-t807a

I just got my new tablet and I am trying to root but don't know which files to use. Has anyone successfully rooted their AT&T tablet? Thank you.

I don't think you can root the att tab s. It has a locked bootloader

^^^^ Just like he said, AT&T does indeed lock their bootloaders. If they arent ecrypted there may be a way around it but thats not something I have any knowledge in as ive never owned a AT&T device.

darn
Awww man wanted to remove all the bloatware. Thanks guys.

According to this tweet, SRS Root now can root our AT&T SM-T807A device:
https://twitter.com/srsroot/status/535510121133391873
I find this a bit suspicious because 1) No one else has root for it, and 2) SRS Root is not represented on XDA. I'm a bit hesitant to try it. Anyone feeling adventurous to try it and report back?

Seems new? I think I seen one like this but idk if this is the same. Well... Since it's based off of exploits by the looks of it, its best to do some more research on it. I might give it a try later idk since it saids supported for the T800 also

I would try it but I have not rooted in awhile and would hate to brick my tablet.

I have looked at it. It use adb and tries bunches of exploit. Since I'm already root I cannot try it. It would most likely not brick your tablet and its worth a try I guess. Up to you!

For anyone wanting to know if SRS Root works, it doesn't. After it connects through ADB, it tries many different exploits before applying the 4th one. Then is prompts that the device is successfully rooted and SuperUser has been installed. It then reboots the device just as CF Autoroot does, but it fails to actually root. This is my 1st device with a locked bootlader, so I'm considering swapping it for the T-Mobile version. Can't deal with the bloatware much longer

Both the T707 (AT&T Tab S 8.4) and T807 (AT&T Tab S 10.5) are rootable, as far as I know. The thing is, it depends on firmware. If you're using NH6 or NJ5, I think you can root. If you're running the latest NK1 firmware, you're out of luck for now.

[Q] AT&T Note Edge Root, Kingroot + SafeStrap?

for a Samsung Galaxy Note Edge (AT&T SM-N915A) Has anyone used ODIN to flash 4.4.4 from Lollipop (which I read doesn't trip knox) and then used Kingroot to get temporary root and then install Safestrap? I didn't really find any custom roms, but when booting from Safestrap, wouldn't root still be available even if you installed the stock Lollipop rom as the SS rom? Or would it be too difficult to remove the recovery if that's present in the stock LP rom so it doesn't mess with SS if you boot from it?

I did use ODIN to go back to KitKat and then used Kingoroot, but the safestrap part your talking about I have no clue. Was unaware of any safestrap for the Notre 4 or Edge.
Back on Lollipop unrooted though. Found the temp root annoying and with FF browser and AdBlock plugin I'm getting by

So it is possible now to get temporary root access using kingroot on 5.1.1 but I am hoping someone get this information to chainfire so that chainfire can use it to come up with a permanent root using odin.

How could i upgrade to 5.1.1 im using 915a in pakistan? Can any on help me ?

hey guys,
I am from Vietnam and i just 've bought the SM-N910A (said that from ATT) in Vietnam. I used RootChecker and Phone INFO to get to check my phone.
The result is my phone was ROOTED!!!. I restarted some times but the ROOT is still accessed.
I tried to use Root Explorer to copy/paste from/into system folder, it's ok like other rooted devices.
I'm following xda-note edge and see everyone's saying that NO way to permanent root ATT note egde.
I also dont know what method the seller used to root my edge, but i think it's permanently rooted.
I've NOT try to unlock bootloader neither install recovery. There seem to be no official method for ATT edge. I am afraid bricking my device.
I upload some screen to show you my note. Thanks and need your advice, guys

When you moved data into /system did you remove it before rebooting, or did you leave it in /system and were still able to boot?
If you could enable USB Debugging and open a shell with ADB and type "ps", then post the output, that may be a place to start.

Recently, kingroot has been able to get root on my note, but after 5-10 minutes I get ANRs and the phone crashes, then I have to re flash with Odin to go back to stock. I have logcat logs up to where it crashes as well.
I'm on 5.1.1

5 minutes after I posted this AT&T tried pushing a security update. Probably to fix this.

Customs boot icon
I rooted my at&t note edge using king root. Then I installed SuperSU and used the option to install binaries in "normal" mode. Then the phone rebooted and in the booting screen i got an icon with an unlocked lock that said "Custom" then the phone booted normally no problem.
I dont know if this information is useful but i thought it was important to share.

Just install TWRP and flash SuperSU.

So there is noway to do this without tripping knox?

bump!

No.
Let me add on a bit to my initial response. Rooting the phone will trip Knox. Has been this way for quite some time. Discussed across many thread here and elsewhere.
Now the question comes up as to what do you lose by tripping Knox? Samsung Pay will never work for you. Android Pay may or may not work. Many people have been able to get it working at least in part, but disable Root (via SuperSu) when using Android Pay. I don't use either of those, so I don't care.
Then the question comes up if this voids warranty. The answer is only if you say "Hey, I rooted my phone and then broke something!" If you need warranty for a physical defect, go back to stock via Odin and you shouldn't have a problem. If you root your phone and then install a ROM not meant for your phone or local (like a Note ROM or an international ROM) you are probably going to mess something up that will be immediately obvious. The solution is not to do that.
Realistically, there aren't a ton of great ROMs available for this phone and most are based on stock anyway. No CM13 as yet. If you can live with your phone un-Rooted, that might be the wisest choice.
That said, I rooted my phone as soon as I got it. I went the full route, didn't care about tripping Knox and still don't. I have run both Renegade and TeamSPR ROMs and have been happy with them.
Now you can decide what to do.

Or u could root ur phone n install xposed on it ... Rooted S6 stock rom is now compatible with xposed its better than any custom roms out there
Sent from my LG-H815 using XDA-Developers mobile app

In my case, I only need temporary root. After that it maybe removed. So it would be nice to be able keep knox from being tripped if possible. Installing twrp is an additional step too that I would like to avoid again because it would serve no purpose since root would only be temporary. I also wanted to be sure that build G920PVPU3CPD3 could be rooted. Thanks for your input guys.

Features lost when Rooting?

I asked in one of the root threads and didn't get a reply. From looking through the existing threads I understand that you lose samsung pay and the hidden folder feature. I can live with those but is there any other features lost when unlocking the bootloader?
1.) Once knox is tripped will features be lost forever or start working again once tablet is returned to stock?
2.) Still shows as widevine L1? Any loss in resolution from an streaming apps (youtube, netflix, amazon prime, youtube tv)?
3.) Any other apps or features not working?

1. I rooted my Note 4 phone and Note Pro 12.2 tablet some years ago. Back then, I did this installing a custom recovery called TWRP. This blows an e-fuse on the main board, which prohibits Knox from working forever. Flashing back to stock recovery can't "unblow" a fuse.
2. Not sure about this one, sorry.
3. In my experience, rooting broke only those apps that relied on Knox. But I suppose these days more apps are likely to detect if they're running on a rooted device and refuse to run. That would account for the popularity of tools like Magisk that try to hide the root state from apps.
After I moved away from those devices (S7 Edge and Tab S3 were next in my history), I abandoned the rooting game. Not sure the value is worth the cost anymore.
EDIT: There are apparently ways to root without flashing a custom recovery -- this was news to me, and shows how long I've not been playing the rooting game, heh.

Thanks for the reply. Yeah I have rooted my samsung devices in the past as well but I believe the last one I did was my note 4 as well but I don't remember widevine being a thing back then or at least I didn't care. Of all the features I am concerned about that. Don't really care about the other samsung features save for maybe dex but I don't think that is affected. Can anyone rooted confirm if they still have widevine? Is any legit premium video app like netflix or youtube tv affected? My oneplus 7 pro had widevine downgraded I believe when the bootloader unlocked which was annoying.

That's not quite true these days.
Using Magisk to root doesn't "blow the e fuse".
Rooting without installing TWRP will keep the warranty status 0x0 which is valid.
BTW: Netflix ect. Works just fine.
It's nice to see old Note 4 guyz around. I was very active in the sprint Note 4 forums years ago. IMO that was the very best phone samsung ever made. @tx_dbs_tx was a mad man of a developer for that device.

100% agree. Once upon a time a Galaxy Note was not just a Galaxy S with a stylus. Alas, it appears Samsung is diligently heading away from what made the Note a distinctive device.

Did you see the picture in the post that was quoted?
It shows as rooted and knox efuse intact. So the warranty would still be good as long as it doesn't trip the efuse.
Look at the picture before telling me a generic answer. I already know that when the excuse is blown the warranty is lost. How do they have root without tripping the efuse?

This is the picture I am referring to.

unlpcking bootloader alone doesnt trip knox but as soon as u flash any custom firmware i.e. disabled vbmeta, twrp, magisk etc. then it will trip knox.
theres thousands of threads on xda alone about tripped knox and what works n doesnt work so id go n look for urself before anything..
and usually it will break ota updates but can depend on device etc. but ull likely have to update via odin
