[Q] How to root my Tab s 8.4

I was going to use CS-Auto-Root but just had a couple questions. After reviving the tablet today, I did numerous updates. Would CF root still work with the new software? The only thing diffrent I can see is the build numberm does that matter? Details below, and thanks!
Model #: SM-T700
Android Version: 4.4.2
Build number: KOT49H.T700XXU1ANK2

Numerous updstes? Anyways, try it, if it soft brivks your Tab S, just flash the stock firmware with Odin.

It shouldn't soft brick it most likely. If it fails it will just revert back to stock recovery and not give you root. Try cfautoroot first then try rooting with twrp.

Impossible to downgrade N910H to kitkat 4.4.4 **challenge**

Dear friends, it's the first time that I write a thread seeking your help.
I purchased my note 4 N910H 5.1.1 few weeks ago and I discovered that battery drains in a horrible fast way even if it is turned off (6 to 7 hours max). I read that many people had the same problem and that after a downgrade to kitkat this issue was solved. So I decided to do so.
I tried all methods I found on forums; all files I found on sammobile. No success.
I only could install 2 files..
1- N910HXXU2COJ4_N910HOLB2COJ2_N910HXXU1COJ2_HOME.tar is a 5.1.1 with CSC from Cambodia (CAM). I don't think it is the good one coz after installing it I could not do an update with kies (shows an unknown error).
2- N910HXXU2COJ4_N910HOJV2COJ1_N910HXXU1COJ2_HOME.tar is also a 5.1.1 with CSC from Iraq (MID). With it, kies accepted to update firmware without problems, so I think it's the good one.
I also found a 4 files ROM N910HXXU1ANJ4_OLB1ANJ4 it is a kitkat ROM but can not be flashed (Odin shows nand writing error). I tries to flash this rom without loading Bootloader file.. it worked but phone was stuck on a bootloop and could start again only after flashing 5.1.1 ROM.
I think that bootloader is locked or secured somehow and refuses all roms.
What is the solution? is there an other kitkat ROM with same actual bootloader maybe? is there a way to change bootloader version?

At first download king root. Temporary root the phone with it then install autrec for your phone model and flash twrp. After that boot into twrp and flash super su.zip. finish.....you have to try multiple times with king root if you don't get it work first time.

Sorry bro than... you have to get temporary root at first then you will get permanent root..
Another option is downgrade to v30b kdz with lg up and gain root access then again flash rooted v30n firmware...

If baseband displayed to 30n , so its changed also modem on twrp.

Verizon Note 4 refuses to root!

I have just received a Verizon Note 4 from a friend which had a stock, untampered with v6.0 on it.
I downgraded it to 5.1.1 and have been trying for over 2 days now to get it to root. I have KingOroot and Kingroot both and most times it says root was successful but the root checker says it wasn't. I have tried at least 30+ times to get this to work. I have even went forward with minimal adb without running the root check and gotten up to the point entering the $ su step and then nothing! Most times it won't even get that far.
I cannot figure out what's wrong?? I even tried one click root but it says it cannot work on my device.
I have the following

I have been rooting phones for years and I have NEVER come across one like this.
Is there a custom or stock ROM that is already rooted I can flash maybe?
Any assistance would be GREATLY appreciated
Thanks
Tom

I had same problem. Once I succeeded on BPA1 firmware but KNOX seemed to have interfered with the root, phone rebooted and root was lost. It seems only the developer version is rootable with Chainfire's auto root.

Would it help if I downgraded further to 4.x.x maybe? I was able to downgrade from 6.0.1 to 5.1.1.
Any suggestions?
Thanks
Tom

Hello all!
I FINALLY just finished rooting my Verizon Note 4 after several days of trying. The instructions are very detailed and I tried to follow them to the T, except I ran into a couple of minor differences when my phone went to TWRP and it was a little confusing.
The other problem was when I was using Kingroot or KingORoot, for some reason there was a message that was not popping up asking if I wanted to allow the rooting process to go forward or something, but I finally spotted it this last time, hit allow and it FINALLY let me get Odin to run completely and I am rooted!! I think the problem was I didn't have the SIMM card in and the stupid window telling me I didn't have the SIMM installed was blocking it or whatever. This issue should be added to the instructions.
Just wanted to let anyone who was trying to help that I got it rooted!
Now I need to figure out if I should stay with 5.1.1., or can I upgrade back to 6.0.1 or flash a custom ROM or what to do next before I switch my SIMM and start using the N4 permanently? I'm fortunate that my old Note 2 is still working barely until I decide what to do? I also need to transfer all my text messages and apps to the new N4, but not sure if I can do it with the back to back method or if I should just do it manually?
Any suggestions would be great!
Thanks again to all!
Tom

Yep it starts with 15.

Ok then follow the instructions in the video to downgrade to 5.1.1. If you are successful with that we can take the next step and root it.
Let me know what happen's!

Factory reset from within device and then recovery. Then kingroot version

Thanks mojoswagger...
I got it downgraded and rooted finally. Now, would you know whether I should stay with 5.1.1 or upgrade back to 6.1, if that's even possible without losing root? There's some features on this version I don't particularly like compared to 4.2 but I can live with it. I'm hoping 6.1 win be better...
Thanks for your help!

Note 4 - Android 6.0.1 - Downgrade? Or Fix? -- Neubie here

Hi, I've got this one Note 4 that's had loads of trouble presumably since the last security update.
Baseband Version: N910AUCS2EQD1
Android: 6.0.1
Have seen the instructions and all as to how to go about downgrading BUT one site I came across with the original stock firmware downloads outright state how:
""DO not ever try to downgrade from any newest Android 6.0.1 Marshmallow updates back to an older 6.0.1 build version""
'and so I'm lost. Should trying to then reinstall the same Baseband version atop what's already there a good first alternative? ...that is, just in case it was never upgraded properly in the first place? Or is that not even possible?
Is trying to downgrade at all a futile pursuit?
Would truly appreciate any suggestions, help, direction...heck, anything! Thanks in advance.

I downgraded from 6.0.1 epk5 to 5.1.1 with no problem.
Not sure about qd1.
As long as you have the odin firmware, I see no problem.

Can i downgrade note 4 n910a from marshmallow to lollilop,please help me i am in great trouble because marsmallow update is very bad with a lot of reboot issue ,battery drain.

Once you are on QD1 you will not be able to go back to anything lower than that firmware. The bootloader is now at the latest version and has blown one of those imaginary "e-fuses" so that you can not go back in time to any other vulnerable OS. I just tried today to go from EQD1 to EPK5 and It would not flash and would fail every time whilst using the latest Odin. So good luck on finding anything on getting you back to another firmware version but at this time I do not believe there is anything that will move you back to the firmware you want. If you do happen to find something or make your own exploit do tell @sanaullahkhan371 If you are on QD1 you are not going to be able to downgrade if you are on PK5 you can try the Odin downgrade method that will5 presumably used but if you are not in this firmware use case you are SOL.

Hi,
Can you please let me know how did you downgrade? Is it straight away flash to 5.1.1 or did you follow any steps?
I am also planning to downgrade. Anyways, I stopped using Note 4 after update to 6.0.1 as it was switching off every now and then due to update. Might as well make this phone usable to take photos and as a video player for my kid
Thanks

I just odin to this firmware N910AUCU2DOI2-5.1.1 It s available somewhere on this forum.
Read how to odin if you never used it. In this case you need to unzip the file and load AP, BL, CP and CSC files on odin and flash.
Was running 6.0.1 epk5 previously.

Were you ever able to flash back to an older version from QD1? Others have said that the bootloader was not incremented in QD1.

I'm also on EQH1. I have never tried to downgrade. I was just curious if it was possible, in case a root method was discovered that only worked on older versions. But I've just learned to live without root. EQH1 works fine for me.

I had the infamous freeze/reboot/shutdown issue with 6.0.1 and I wasn't sure if that was the issue but I downgraded to 5.1 and have fewer issues now. The phone runs just fine, except it does not reboot. You have to do a soft reset every time. But with the Wakelock app, at least it runs.
