I rooted my phone a while back and installed CWM recovery. I flashed several Roms successfuly. However when I installed my new ROM( currently omnirom) the supersu app is no longer there. I wanted to try titanium backup but when I installed it, it says I don't have root access. I redownloaded the supersu app and the install keeps failing. So I have a few questions.
1. How did I lose root access to my phone?
2. Can I install custom Roms without root access?
3. What steps should I take to regain root access?
BTW my phone model is galaxy s3 i9300 model.
If you still have access to the recovery you can probably just reflash your ROM and gapps, clean cache and dalvik cage and should be up and running again.

I still have access to CWM but my problem is how to get titanium backup to recognize my phone as having root access.
I got that. If you reflash your ROM and gapps with just deleting cache and dalvik cache and *NOT* data, you won't lose any apps and probably regain root access. Make a backup from within the recovery though. I can't tell you why titanium doesn't make a root prompt appear but this way you will probably fix it

Also there is possibly an option under development settings where you can choose if apps are granted root privileges. You'll want to check that option.
These are screen shots of what i see when using supersu and titanium backup. I will try your suggestion of reflashing my rom and gapps and see if that helps with anything.

I tried this suggestion and I still don't have root access. Have no idea what else I should do.
Ok I got it to work by manually downloading supersu from http://forum.xda-developers.com/showthread.php?t=1538053
and flashing it from my recovery.

So I rooted my tab using odin. I just recently flashed a rom and decided to revert to the backup I made after gaining root. After the backup finished installing I went to install apps such as titanium back up and I get the "unable to gain root permissions" schpeal. Did I lose my root?

Edit: it seems performing a factory reset/wipe removes root. With cwm installed in backups, you can simply re flash root.zip.

CF-Root kernel ... which version?
v5.4 and 5.5 are using SuperSU - not superuser.
Maybe there is a conflict between those two?!
1. Try to start SuperSU app and update binary if this option appears.
2. If that does not help, flash the CF-Root kernel again to your phone.
3. If you get these root issues again, try to wipe cache partition and Dalvik cache in recovery mode.
Sometimes this can help.
Good luck !

Deleting either cache will not erase your data or apps. You can try what IT_LER suggested.
If it didnt work, One suggestion is try to download extweaks from play store. In the MISC tab, there is an option to remove root. So you can go ahead and do that. At the same time, below that option, there is a checkbox which says install root on reboot in which will install root again.
So remove root and make sure that install root on reboot option is checked then reboot.
I am also not sure why did you go with CR root method. Here is the best and safest way to root your GS2 in my opinion:
http://galaxys2root.com/galaxy-s2-root/how-to-root-galaxy-s2/
You can also try running fix permissions after re installing root from CWM advanced menu link.

ExTweaks app will check the kernel, if it is compatible.
And CF-Root kernel is not.
So, that will not work until you flash a compatible kernel, such as SiyahKernel from gokhanmoral.

No, that's why I recommend to wipe cache and Dalvik cache first to try to solve issues.
The first start after wiping the caches need a bit longer, as the system will generate the cache again ... for every app.
But it will not clear app data or apps itself or any other data on your sd card.
Only app/system cache (and Dalvik cache = Java Virtual Machine cache).
hello sir .. i tried wiping the cache ONLY ( because i dont know to wipe dalvik ) and it worked like a charm! tnx sir
I have an International Samsung galaxy S3 (GT0I9300) which is about 2 years old.
I tried rooting it using chainfire's odin installation method. The link I used is this: http://forum.xda-developers.com/showpost.php?p=33305784&postcount=2.
I followed all the steps correctly. All went fine until the red android came up on my phone. Then after all the process was completed, odin also showed done! But, my phone did not bootup. It is looping in the Samsung logo bootup screen.
I tried all possible methods to turn on the phone, but it still stays in the boot screen itself.
Also my phone is not going to recovery mode when i press <VolUp>+<Home>+<Power button> so that i can wipe cache data, instead it just displays the android recovery logo for a second and reboots again and loops in Samsung logo screen.
I have very valuable data stored in the phone which is not backed up!!
This phone is my daily driver, so I would require some urgent help regarding this...
Please, give me a solution to make my phone work normally as before and also help to root it if possible without any hassle!!
Thank you!

Couple of things you could try (1) flash a stock rom with odin this should restore your phone but you will lose your data (2) flash a custom recovery with Odin either Cwm,PhilZ, or Twrp when finished flashing you can boot into recovery and wipe cache etc.

Will flashing CWM or any of those custom recovery and wiping the cache help in rebooting normally as before? Because I don't want to get into another trouble. Can you kindly give me a link to it? And how to remove that custom recovery if i wont require it?

Link here please read instructions fully >> http://forum.xda-developers.com/gal...covery-clockworkmod-touch-6-0-3-2-gt-t1719744 << Ideally you should wipe cache and data to stop a boot loop (but obviously you don't want to lose any data) so try wiping cache to see if that works. Even though you are stuck in a bootloop the cf auto root flash might have worked so you can try to backup data in recovery and see what happens.
To remove custom recovery you will have to reflash stock rom with Odin and you may have to accept the fact you may lose your data if it won't backup in recovery.

Alright!! Thank you!!
I'll try this method and reply if it is working.
@tallman, I just flashed the clockworkmod recovery and wiped the cache partition.
Then as you mentioned I also tried backing up from backup/restore option.
The cache is wiped properly.
When i tired backing up, i saw two or three lines of message log from CWM and then device just boots up and is stuck at Samsung logo boot screen itself again.
Any other solutions?

Looks like the root didn't take if I where you I would flash stock rom with Odin from Samfirmware (factory reset after flash) you will lose your data but you will have to put that down to experience.:fingers-crossed:

@tallman, Thanks for the advise!
Why didn't the root work?? I thought the root worked as CWM requires root permission right?
Is there any other way to just bootup my device without having to flash a new ROM?? What is the reason for the root access to be denied? Can it never be rooted?
PS: Because I don't wanna lose any data. I had about 250-300 apps which I have been using and had saved a lot of info in them.

Yes you can boot to cwm again and wipe data cache etc but like I said all options now involve loosing your data.Plus this is not guaranteed to work depending on what whent wrong with your cf Auto -Root flash.That is why I suggested flashing back to stock with Odin this will return your phone to how it was before it was messed up (minus your data of course).

Okay thank you for the help!!
I'll wipe the data or flash a new rom.
Will stock rom not require root access?
Is flashing a custom Rom same as flashing the stock Rom?
Anyone else have any other suggestion?

Sorry just saw your question about cwm requiring root..No Cwm or any custom recovery does not reqire root, recovery is a separate partition root is acquired through your rom. Technically you can flash a custom recovery and a custom rom without root because root is included in all custom roms.You need root to access system files that is why cwm failed to backup your data because it needs access to your system which it cannot have without root.Stock roms don't have root built in that is why you need to root them to access system files unlike custom roms which like I said have root built in to them

Oh! Alright! :good:
So I guess I'll be flashing a custom rom with kitkat as I'll be losing the data anyways.
All the data in external sd will be intact right?

Yes ext sd will be fine this is where you will need to put your custom Rom anyway to flash it.Please read all the guides in the stickies before you start to make sure you know what you are doing.Also read the stickies about backing up your efs (VERY IMPORTANT) because if you don't back it up then you may have major problems later if you run into problems.

Is there any way to root my phone again and try backing up the data?? Will it work?
Or is there any working recovery software so that i can create an image of the memory?
Hi,
I'm using CM13 on my LG d620, recently I tried installing SuperSu, and then updating binary, but normal way did not worked so I tried to install it with TWRP recovery, so my phone rebooted into recovery, supersu script automatically stared and installation was successfull. I wiped cahce, even dalvik just to be sure, and rebooted system, but it is now stuck in bootloop.
So I'm just curious if anyone would know if I can somehow fix this problem, maybe through recovery, flashing some script, or in terminal in recovery, with adb... pretty much anything just to avoid flashing new rom again and losing all of data and setings....
Thanks in advance
(btw, i'm on cm13 6.0.1, latest update to this day, twrp 3.0.0, supersu latest version on google play store i think, and also have enabled root access)

Just flash rom from the recovery, thats it. Let me know if it worked for you
Hi. I tried rooting my phone a few months ago, and installed TWRP and ashwin007's CyanogenMod. The rooting seems to have failed (I think I accidentally wiped something when I installed TWRP/CyanogenMod/GApps, causing me to lose the root or something. I'm not exactly sure what went wrong), but I managed to install TWRP v2.8.7.0 and CyanogenMod (on the 10th August nightly) successfully. Now I want to try rooting my phone again properly (with superuser access), and change my CROM to probably http://forum.xda-developers.com/one...m-kernel-unofficial-cyanogenmod-13-0-t3375221 (This also includes a newer version of TWRP right?)(I also want GApps!). I'm not sure which order I should do these tasks.
Should I just follow the instructions in the link?:
Installation instructions (for first-time installation):
First, perform a backup of your existing setup, and then perform a clean install (wipe /data and /system; TWRP is recommended).
If you plan on using encryption with this ROM, then flash the custom TWRP build in the Downloads section below before flashing the ROM. This custom TWRP build is needed if you want to be able to access data encrypted using this ROM while booted into recovery. Otherwise, you will not be able to access your encrypted data while your phone is in recovery mode.
Then, flash the ROM, flash a Google apps package, SuperSU if you want root access (ONLY v2.65 OR HIGHER), and then reboot.

A few things I want to clarify:
1. The SuperSU installation page says it requires a rooted device. As stated earlier, I'm not 100% sure whether my device is rooted or not. What should I do? Root my device (What's the best way also, KingoRoot or something else?), then follow quoted instructions?
2. For the clean install I just wipe /data and /system? Not System, Data, Cache & Dalvik?
3. After I finish wiping and installing all of those, is there any way I can restore all of my apps and associated data that I had? (I've heard something about using TitaniumBackup?)
From what I've read, I probably should:
Use my TWRP to backup all the other things (system and stuff)->
Root phone (using KingoRoot?) ->
Download and use Titanium Backup to backup Apps ->
Wipe /data and /system (or System, Data, Cache & Dalvik?)->
Flash new custom TWRP (Can I flash it using my old TWRP? The TWRP official website says you can do this with TWRP versions v2.8.4 and above, mine is v2.8.7, but that was for the official TWRP)[or should I use the android SDK tools bootloader thing?] ->
Flash new custom ROM with TWRP ->
Flash GApps with TWRP ->
Flash SuperSU with TWRP ->
Reboot phone->
Restore apps with Titanium Backup
Could someone confirm? I don't want to brick my phone Thanks a lot!
Just follow the guides for rooting and custom Recovery's. If you follow the steps you won't have any problems. First thing you must do is update your twrp. Assuming you have already unlocked your bootloader.
