I've never used a toolkit on my HTC devices, so I can't speak to their effectiveness. Perhaps they need an update to work with Lollipop.
I recommend using TWRP recovery (just because it's the one I used and I know it worked for me. Can't speak to CWM or Philz)

Galaxy S3 T-Mobile SGH-T999 root fail

Hola,
I am trying to root my sg3 t-mobile, I used Odin to install clockwork and everything went ok (It said Pass). Then i tried install CWM-SuperSU-v0.87 to gain superuser access but I keep receiving the message when I install from recovery:
e signature verification failed

and the phone reboots. I used these files for rooting from this tutorial.
Can you help me?

Wow! That is very very old! You should read the sticky threads and search the General and FaQ sections for more recent info.
Also search xda for SuperSU and you'll find the version you should be flashing is 2.46. (Probably all you need)
Or, depending on your firmware build, you can just use Towelroot. (Page 1 in general section)

manual root
The thing is that I want to install manually root access because I want to install clockworkmod and a costum ROM. Although I installed towelroot as you mentioned and I granted root access, now if install a costum ROM the towelroot app will be deleted so I loose root access right?
I also tried flashing SuperSu 2.46 before towelroot but still, no root access.
Thnx.

Any rom you flash will be rooted so you don't have to worry about that. Just flash your recovery and then flash your rom. That's it.

Rooting is not required to flash a custom recovery and custom ROM.

Then,what's the root for? So we can just copy the roms/recovery zips into our sd and flash them?

Root allows you to read\write the \system partition, and parts if /data that are also protected. It only affects things when booted into the android OS. There are lots of things you can do with it. Debloat, modify, tweak, etc.
Pretty much all custom roms are already rooted, and all you need to flash them is a custom recovery.

Systemless OTA upgrade

I know there are several threads covering similar things, however I still can't find the relevant info for my specific question.
I am on 6.0 Build L
I rooted using systemless root - I have changed nothing in my system partition as far as I know as I wanted root for AdBlock and TitaniumBU.
I am using the stock kernel too.
TWRP 2.8.7.2
I now have a 6.0.1 OTA - but I'm 100pc confused as to exactly how to go about installing this.
Some people seem to say OTA on this setup will work fine on similar setups.
Others say I need to flash 101 things to get it working.
Literally no idea.

How I Did it...
From a site with this in the title:
can_i_manually_flash_601_also_does_ota_work_with
Systemless root doesn't break ota, non-stock recovery breaks OTA.
Unlock bootloader, flash 6.0.1, flash TWRP, flash systemless root...
I did this:
Went back to stock recovery, by flashing via ADB, rebooted downloaded and attempted to install OTA on phone. Process started, rebooted, proceeded and then failed with error . Rebooted, got Factory image.
Extracted and ran flash-all.bat ONLY AFTER Removing the -w from this line:
fastboot -w update image-bullhead-mmb29k.zip
Got latest SuperSU v2.61 zip with auto boot patcher:
See androiding.how/android-6-0-1-root
Copied this to Memory on phone.
Flashed/Installed TWRP Recovery using ADB.
Booted into TWRP Recovery and installed SuperSU.
So now I'm running systemless rooted 6.01 on a Nexus 5X with mmb29k and every thing is working.
I think even though I rooted systemless 6.0, the modified Boot Image was still not letting OTA work.
We shall have to wait and see on the next OTA. Maybe just going back to stock recovery will be all that's needed.
There are some ADB commands that allow you to temporarily select a recovery image, but I'm not sure how that works.
Good Luck!

How to remove Root from Galaxy Tab S?

I bought a second hand Samsung Galaxy Tab S a few months ago and it has been working fine.
However, when I looked at version of Android then seems a bit old (5.0.2) and when I did a check for updates it said that it couldn't update because "The operating system on your device has been modified in an unauthorised way". When I checked then it seems that the device has been rooted.
A quick search suggested I should run SuperSU to remove the root. So, I had to download and install this, but, when I run it says "The SU binary needs to be updated. Continue?" - if I do then I get another message "If you have a custom recovery like TWRP or CWM that can be used to (try to) install the SU binary" and gives me a choice of Normal or TWRP/CWM. I am struggling to know how to proceed.
So, should it be possible to remove the root and still preserve all my data, apps, settings, etc?
If so, is SuperSu the way to go or are there other tools I should look at, such as Kingo Android Root?
Or, am I faced with rebuilding with a stock ROM?
Thanks

There is no update. 5.0.2 is the latest.

If your root manager is supersu then it has the option to unroot in it's settings.

I've tried to fire up SuperSU, but, run into problems, as described in my initial post, and this is what I need to resolve.
Any ideas?

I'm having a bit of trouble understanding the end goal. As stated Android v5.0.2 is the latest non-custom firmware available. As a previous owner has unlocked the bootloader and seems to have flashed a SuperSu version that modification is blocking any OTA update to v5.0.2. It is also clear your trying to avoid loosing user data.
Would it be acceptable to be rooted and use a different method to apply the latest Samsung stock firmware for your region? If the answer is yes install a TWRP recovery for your device model but you'll loose your warranty by tripping KNOX (you may already be in that state). Follow the instructions in the TabS TWRP thread.
Then finish the SuperSU install (where your stuck today). Then install Flashfire. With Flashfire and the downloaded latest Samsung firmware package you can flash the boot and system images to update your install then use ODIN to update the Bootloader image from that download firmware. You could also flash the recovery image but that would overwrite TWRP and in your case I don't see the point. Flashfire needs the whole Samsung firmware file to be available on the device itself unlike when using ODIN to flash the Bootloader image.
As I'm rooted but retained my warranty I use FlashFire and ODIN to update to the latest stock firmware and never loose user data. Unfortunately to root and not trip KNOX I did wipe my user data that first time so it does not seem to be an option for you.
Hope that gives you some ideas. In your current state it maybe as simple as completing the SuperSU install (assuming a custom recovery (TWRP/CM) is already installed) then using Flashfire and ODIN as described.
Good luck

Thank you for your very helpful and comprehensive reply. I can't profess to understanding all of it, but, I am sure I will get there eventually!
I shall follow your suggestion of trying to get get SuperSU installed first.
:good:

If you want to go back to stock just flash the latest firmware with odin.

[Q] Lost Root

Running N910PVPU4DPC1 [http://forum.xda-developers.com/note-4-sprint/development/rom-t3352832]
It's been running fine for the past month or so, then yesterday, I went to run Titanium Backup, and it said my phone no longer had root access.
---------------------------------------------
SuperSU
There is no SU binary installed, and SuperSU cannot install it. There is a problem!
If you just upgraded to Android 5.0, you need to manually re-root - consult the relevant forums for your device!
---------------------------------------------
I've tried to re-root via CF-Auto-Root, it'll complete without error, but still no root access.
Anyway I can get root back without blowing out and starting from scratch?

If you have recovery just flash SuperSU itself.

Thanks for your reply SaintZ93.
Just tried that via https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip
Uninstalled my previous version of SuperSU, booted to TWRP 3.0.2-0, no errors on install, fire up SuperSU, I get the same error message as before.
I was really hoping to get SU back with out having to go and reinstall everything. Doesn't look like it's going to work out that way.

Actually I just noticed the same thing, its quite weird, I lost root also. I had root working fine with PD1 now its gone.

I believe a security update was pushed, well at I know one was on my Sprint Note 4, and I think it auto installed that's what made me lost root.
I simply flashed supersu from TWRP and I had root again.
Don't know if this would help, but I turned off firmware updates on my phone and haven't had an issue for the last 3 days.
I think the update was pushed out on Tuesday or Wednesday because I noticed I didn't have root on Thursday.

I believe that the SuperSu that comes with that ROM is systemless, which you would need to flash SuperSu 2.68

I am in the same boat.

That worked like a f'n charm!
I uninstalled SuperSU, downloaded SuperSU 2.68 [https://download.chainfire.eu/924/SuperSU], installed via TWRP, and verified!
Thanks for all the help!

can I stall SUPERSU 2.68 with stock recovery? how?
I extracted the 2.68 zip but can I install without a custom recovery?
