[Q] Rooting and Unrooting help for Mega 5.8 - Samsung Galaxy Mega

Guyz Help me on this.
I tried to search for proper answer on how to in other threads, but didn't found.
I have Mega 5.8
I rooted it few months ago with odin and have SuperSu app and bunch of other apps like Nandroid manager etc.
I am not much of techie but wanted to try out this rooting stuff.
However I didnt flash any custom ROM. I kept the original intact.
Now my device status & current binary status says custom in download mode.
I want to unroot and restore all back to official.
How to do it.

If you have SuperSu from chainfire then under sttings there is an option for FULL UNROOT. Try that...

download a new rom
Download an official ROM from sammobile and flash through odin. thats the only way out.

To back up your current rom you will need to root your phone and install a custom recovery to do a nandroid back up. Otherwise you can download a copy of stock rom from www.sammobile.com/. I do suggest to check the website has the right one for your phone and download it first before you start the process

[Q] Rooted - or not

Hello to everyone
I am the proud owner of a galaxy S3 - i9300 since couple of days (got s2 before) and I would like to install a custom rom. Right now it is official JB. So first I tried to follow the guide from here the galaxys3root.com - galaxys3root.com/galaxy-s3-root/how-to-root-galaxy-s3-jelly-bean-or-ics
I finished installing, everything said ok but SuperSU said "“There is no SU binary installed, and SuperSU cannot install it. This is a problem!”. However I was able to enter recovery mode and see that cwm was installed. I repeated the procedure - same result. I tried using the CF-Auto-Root-m0-m0xx-gti9300.tar.md5, it said ok, finished, all green but again i had no root access (cwm still there, root checker said no root and supersu dissappeared).
The ultimate goal for me is to install CM11 rom with kitkat. So please clear some things for me (almost beginner level):
1. do i really need root from now on?
2. can i just reboot into recovery, wipe data/factory reset and install ROM? (all from the device, no odin)
3. is it a better solution to flash stock firmware through odin and start rooting all over again ?
4. Why don't I have root access since I followed all the indicated steps?
One detail that might matter is that now my cwm is version 5.5.0.4 CF v.1.5
Thank you for any help (and again, beginner+1 language please)
Visit CM and CF autoroot site you will find the answer to your questions.
All you need to install CM is recovery, so if you can get into that you are golden and don't need root on your current rom because its going to be over written with CM anyway
Thank you for your replies!
IOU-1, I did some research over the internet and I still do but I'm looking for some straight-on answers right now.
Darke5tShad0w, thanks for your help - right now I have cwm 5.5.0.4 - can you point me towards how to update to newer one? (I cannot do it through play store since I don't have root access).
Ok, I've found the cwm update: http://forum.xda-developers.com/showthread.php?t=2052091 I think this should work.

Try this since your goal is to install CM-ROM http://wiki.cyanogenmod.org/w/CyanogenMod_Installer
Sorry I dont have alot of time today to be able to find you a link for the updated version.
Few things you can do here,
Use the link IOU-1 posted, I forgot about this yesterday then update CWM with rom manager
Try to flash cm with current CWM, if it works update it with rom manager
Search the forums and find the correct cwm post and update manually
Ok, thanks to everyone for their answers.
I fixed it and I'll say how so anyone in my position will do the same.
As a reminder, I tried to root but all I succeded to do is get cwm installed but no root (so no rom manager or any other root app installed).
What i did was to update cwm manually from within it, with zip install from this thread: http://forum.xda-developers.com/showthread.php?t=2052091
After that I simply installed CM11 - zip install - and now I have root and everything is running smoothly.
Again thanks - and good luck to all.

[Q] Problems with rooting

Hey there. I want to install CM11 to my I9205 but I can't seem to root it. I've read most of the threads about it, but nothing works for me. It just shows me a security warning from KNOX and SuperSU says that there is no binary installed.

You probabely have OTA update recently... now you have ROM with Samsung KNOX security system and with new bootloader. If you want to root your Mega and you are willing to accept irreversible tripping Knox counter (= warranty void) you can find many tutorials how to root ypour phone and disable Knox. Basically it needs essentially to instal custom recovery using Odin and then installing Super user from recovery. But ask yourself the troble to find exact procedure.
Note: now you can not downgrade your firmware to version without Knox. Any attempt will end in bricking your phone.
So if you want CM11 you have to root (with tripping flash counter = warranty void), installing custom recovery CWM or TWRP and then installing CM11 ROM nad choosen version of gapps (ROMs AOKP or CN type are lacked all Google apps so if you wnat it you have to flash it separately)

Thanks for the reply. I've managed to install a custom recovery, but I can't seem to make the root work. I have tried both CWM and TWRP, and still can't get SuperSU to work properly.

try to use this information.
As I said in other place - in such situation the best way is to start completely anew:
- Download firmware (e.g from Sammobile)
- Install it by Odin
- Install custom recovery
- Root phone
In provided links you should find detailed description how to do it. Bear in mind so for successfull installing custom rom's you HAVE TO disable KNOX e.g as is decribed there

Galaxy S3 I9300 Rooted RevolutionaryROM- How Do I revert Back To Stock Firmware?

HELP ME
Hi! I own a Galaxy S3 I9300 1GB RAM, 64GB which I've rooted, changed its ODIN and installed this ROM and now I'm very sorry I've done that. I ask you to help me, telling how can I install back the stock ROM, which is this one.
I'm not experienced in stuff like this at all; when I first changed it to 4.3.0 from 4.1.2, I've installed another recovery mode (like Safe Mode in Windows) called TeamWinRecovery, from where I installed afterwards the 4.3.0 ROM; now, to install that 4.1.2 again I have to change it back to the stock 'Safe Mode', and this is where I'm stuck. I followed all the steps to install the ODIN shown here but it doesn't work. PLEASE HELP ME!
Here are the steps that i followed
1.Download the stock rom(sammmobile)
2.Flash it via ODIN and you are done,but there's a counter which will indicate if you ever flashed a custom rom,i never tried to clear it as i was not worried about it
For removing the counter if necessary, you could use Chainfire's TriangleAway.
You can find the firmware you need at SamMobile, as already mentioned. Just click the link and select the language your region.
Then get Odin and flash the firmware.

SGS3 I9300: Root and Custom Recovery lost after CM13 (Root enabled in dev opts)

Dear All,
Sorry if am re-posting the same, and as am new here and need an urgent help, started this thread.
1. My Samsung Galaxy SIII International (I9300) was rooted and I had CM11 stable/snapshot version there since last 2-3 weeks.
2. Yesterday, I tried upgrading the latest CM13 nightly for my device.
3. While doing so, and rebooting, it asked me the normal message "root possibly lost, fix, yes or no". I accidentally pressed no.
4. Then I noticed after CM13 was flashed, that I do not have root access anymore. Please note that at this point in time, I was not aware that it has to be explicitly enabled in developer options.
5. I came to know that I lost root when I tried to boot in to recovery (CWM) to install gapps.
6. Now, under the impression that I do not have root anymore, I tried to root again with Odin as I had been doing all these days.
- By doing that, ODIN removed my custom recovery (CWM) and flashed it with stock recovery.
- Though ODIN said PASS after reboot, I still do not have root access.
7. Removed cache, wipe data, and factory reset, multiple times but no help.
8. Enabled root for both apps and adb in Developer options, but no use.
9. I also tried KINGO root ( a very popular tool for SGS3 these days) but in vain.
10. Now, am stuck with CM13 and stock recovery and unable to do anything with ROM manager or anything else as I do not have root anymore.
11. Am able to install few apks for whatsapp and facebook for now and living with it, but it wouldn't let me install playstore apk too anymore.
Highly appreciate any quick feedback.
Many Thanks,
BR,
Shiva
I belive you need to flash the stock 4.3 jellybean rom with odin, and root it afterwards.

TWRP 3.0.0..???????????
First of all.. Update TWRP to 3.0.2, you are NOT supposed to see the message that tells you that root is gone, as (official) CM13 includes root from now on.
For root, inside Android go to Settings > Developer Options > Root > Only apps.
Do it via Odin as only 3.0.2 is available in a .tar file (latest version), should not be hard.
Not only that, but upgrading from CM11 to CM13 is not recommended, as it causes multiple compatibility issues with installed apps (afaik).
You are better off with wiping it all and install CM13 Clean, and if you decide to; you must also flash Gapps (optional) directly after CM13 (no reboot).

SGS3 I9300: Root and Custom Recovery lost after CM13 - SOLVED
Dear All,
Thank you for your valuable advice and suggestions. I used ODIN to flash back to stock ROM and now everything works as it is like out of the box. I will root again perhaps in a few days and the flash the stable release of CyanogenMod. Will keep you posted. I wish the Android M snapshot is released by then.
Thanks again,
Cheers,
Shiva
