FolderMount
I flashed it, but after that I lost my root permission. After towelroot I have root permission again, but foldermount causes reboot again. How should I fix this issue?

Remount reboot problem for Experia LT30p
I rooted my Experia LT30p phone and installed PhilZ Touch Recovery according to the instructions at http://forum.xda-developers.com/showthread.php?t=2798411. Afterwards
I followed the instructions at http://forum.xda-developers.com/xperia-z/orig-development/lb-definitive-root-remount-reboot-fix-t2317432 and installed the BusyBox app by Robert Nediyakalaparambil, opened this app and selected "install (requires root)" (I am assuming that that is ment with update your busybox). After installing Link2SD the phone keeps rebooting. Only if I remove the SD card, the phone boots properly.

Waiting for device, connect usb cable
Like @asbesto "I am stuck at Waiting for device, connect usb cable" even after follow those steps that he did it in this guide...
I'm using Xperia SP C5303, Android 4.3 12.1.A.1.205 rooted (SuperSU) and already installed BusyBox
Any ideas ?

I try to root my Xperia M C1905, entered in instal in remountreboot fix, and it didn't find my device there. I enabled USB debugging. Thanks in advance. Just says waiting for device, connect USB cable now...

In post #281, chemcup had a problem with errors due to read-only file system, e.g.:
cp: can't create '/system/bin/killric.sh': Read-only file system
I had the same problem with an Xperia LT30. This is a factory unlocked version direct from Sony (but my BL is still locked).
I ran across a ticket mentioning that doing an "su" first allows remounting. See the note by Blister Bee.
https://jira.cyanogenmod.org/browse/CYAN-5908
Anyway, went into adb, did the su remount, and then ran the script and it worked!

Root Vanished.
Everytime when I run the program and apply Remount Reboot Fix, it breaks my root. What to do, I have Sony Xperia M, running 4.3 android.

[[Solved]] [[Guide]]How to apply remountrebootfix on locked boot loader.
I have seen many peoples facing the problem of reboot even after the remountrebootfix so I m posting this idea.
I have applied this method on my Sony Xperia M, and got a full root access. You may also try it manually...
Warning- I will not be responsible for any damage caused to your phone, you are doing it at your own.
1. Download towelroot apk by Geohot...
2. Open it and click make it rain. Now you will get Half root access.
3. Now download remountrebootfix flashable zip and extract it somewhere you remember on your sd card.
4. First of all you need busybox for this, I think you would have already installed the latest version of it previously.
5. Now go to system/bin in your phone's root and if you find ctrlaltdel and killric.sh then delete them. And paste new ctrlaltdel and killric.sh from the extracted folder. Now reboot your phone.
6. After that download latest version of foldermount from play store, and try to mount any folder, if it fails then it will show a message to fix the rom, fix it and then again reboot. Now Foldermount will work perfectly.

make changes undone
Hi NUT,
i just wondered if you could implement a feature to make the fix undone. This could be useful if i want to use the OTA update again that seems to need RIC service to run for verifying system.
The reason i asked is because i tried to unroot via SuperSU option "completely unroot", i removed the manually done SD fix and tried to install the OTA. It fails half of the installation because i think the RIC service is not up and running and therefore it recognize a system change.
...would be really cool though. Thanks NUT for your hard work. I'll appreciate it!
best regards

Can't edit or write data on my phone after rooting.

I f'ed up guys, it seems that after rooting I dont have access to edit data on my phone, it can boot and all, but I cant for example take pictures(says it doesn have space wich is not true), intall apps, etc. I dont know in what extents it affected because I can uninstall apps for example.
When I try to delete a file with a file explorer it says the access was denied. Nor I can copy files from my pc to the phone.
I have a XT1063 with lollipop 5.0.2 that I installed manually before and worked great.
I installed Super SU through TWRP 2.8.5.0 (maybe wasnt compatible with lollipop?) that have Super SU 2.4 built in (according to what i’ve read, maybe this version of Super SU isnt compatible?).
Anyway, after that I proceeded to install busybox with default configuration and later smscript, dont know if all this is relevant. I only was aware of the problem when I tried to download a script for smcript but couldnt save it to my phone.
So next I tried to unroot from super su configuration with no luck, only got to unroot after uninstalling busybox. (also uninstalled smscript if that matters).
I hope I gave enough data if you need more just ask, thanks!

[TUTORIAL]Root Without Bootloader Unlock, Replace Kingroot with Super SU

Worked Well on All Lollipop Versions of ALE-L21​
After many unsuccessful attempts, finally i found a solution, and it works like a charm...
First of All Download KINGROOT.apk
install it and run Kingroot... It will take some time to root your ALE-L21.
if unsuccessful, try again, it will surely work after retries... in my case it rooted my phone in third attempt.
After rooted successfully with Kingroot. then another step is to replace kingroot with SUPER SU, because Super SU works with all rooted apps, KINGROOT lack this feature.
I have made a small script to remove Chinese kinguser, all related files and folders, and install SuperSU.
This script will do all the work for you without using PC, just by terminal, first of all, thanks to chainfire for his SuperSU files.
Before starting :
Download and install Terminal emulator app.
Download and unzip "Replace_Kingroot_With_SuperSU.zip" file.
Steps :
Send the extracted folder "mrw" to the internal storage of your device and make sure that this folder contains 4 files
Open Terminal emulator and type :
Code:
su
Allow root permission
Type :
Code:
sh /sdcard/mrw/root.sh
It might display some error, at the end it will launch supersu or open supersu manually.
Update su binary normal, then reboot.
Done !
Now you can enjoy the power of root and Super Su...

You got error because you did not send mrw folder in main directory of sd card, you should send that folder to internal and external memory also to avoid any errors... update me when done...

I'm following your instruction exactly, why not?
how can i blame you if i don't follow exactly what you wrote?
mrw was in root of sdcard, supersu and su binaries are working (if i don't freeze com.kinroot.kinguser) but what i wrote it's valid.
I launched again the script and after a lot of errors this time supersu asked me to reboot, first time didn't; now seems all kingroot trace are gone!
EDIT:
After testing i see that a lot of times supersu needs to be started manually to have the auth promp for an app, my english isn't so good, i'll write an example:
start (first time) an app that requires root
wait for auth prompt by supersu
wait a lot, so open supersu, then it shows the request for authorize
a second app started just after show immediatly the auth promp
When com.kingroot.kinguser was active the promp from supersu was everytime immediate.

Is some chance this work in future on marshmallow ? thanks

Dear saifkhan9187,
How to update superSU?
I got failure message when SuperSU try updating.

Making this I still can get the OTA updates?

Is that ota still available?

Recently, about a month, I got the b188 update... Android 5.0.1

Got the same error first time, reboot, launch again the script (you will see lot of errors this time file are already deleted no matter) then start supersu if not starts; this time doesn't fail.

@ItalianWolf how did you check for unlocked boot loader? Fastboot? Thanks!

@rHycH yes, reboot in fastboot mode and you can see in red that bootloader is unlocked

Uninstall system app

Hi I just rooted my Z1 using KingoRoot APK app and I installed Lucky Patcher to install Floating Fake Location as "system app". The thing is, I cannot uninstall Floating Fake Location afterwards using tools like Root Uninstaller Pro,KingoSuperUser etc. At first I thought it was Floating Fake Location issue but soon I realize I can't even uninstall other Sony bloatware such as Socialife, Xperia Lounge etc.
Please enlighten me why I can't uninstall system app even tho I am rooted.
P/S: it may have something to do with my root (partial? as I didn't unlock my bootloader), as I can't even mount r/w using root explorer or any other app that can mount r/w on /system.

You also need to instal Supersu, which is an interface for granting root. Then you will be able to delete system apps.

I am using Kingo SuperUser to grant the apps root permission. Had some trouble replacing Kingo SuperUser with Chainfire SuperUser but I figured Kingo should've done the trick as well. When I mount Kingo did prompt me for permission and I allowed it, somehow I think the root is incomplete ?

Does your device have recovery installed? You can delete system apps through it: mount /system through XZ Dual Recovery's TWRP and delete the folder with the app's apk inside. You could also try flashing a SuperSU zip this way to fix root, but make sure you don't use the systemless version.
I suggest you next time don't use kingroot or any one-click root: though uncomplicated, they're notorious for being untrustful, leaking private IMEI information to unknown servers, and unreliable. Read THIS thread thoroughly, re-root using the method in the 2nd post, and upgrade to 5.1.1, or get a pre-rooted FTF through XperiFirm.

No I haven't installed any custom recovery.
Cause I am already using 5.1.1 so I figured Kingo Root is the easiest way to go, didn't know it will cause so much trouble. So basically I need to unroot then root again using the "proper" method? I am already on 5.1.1 btw.

The fact that you can't install Supersu and get root indicates that your phone is not fully rooted. I bet you wouldn't be able to install recovery either for the same reason...
Do the classic rooting, install TWRP and then flash any pre-rooted stock rom you want...

I suspect I am not fully rooted as well. Can you point me a direction towards "classic" rooting my my Z1 5.1.1 ? Almost every post I went points me back to one-click-root solution.

I have the same problem, it's because we can't remount /system to rw ("operation not permitted"), so the update to SU isn't working as well, tried several different methods with terminal emulator but without any luck. Neither will total commander help in this situation. I'm begining to lose hope

Exploit maybe works with 5.1.1, but if not, downgrade your firmware to 5.0.2, use Easyroot to exploit, then upgrade back.
The "classic" root I was referring to requires downgrading from Sony's Lollipop/Kitkat FW to Jellybean due to Sony patching the exploits in the newer FW used for rooting. The steps are outdated now and is replaced by Easyroot. http://forum.xda-developers.com/showthread.php?t=2688933

Rooting LN14????

Could someone please point me at instructions on how to root LN14.
I've searched the HD/HD+ forums for 'root LN14' and 'rooting LN14' and got no results (which by itself is suspicious).

have you enabled Developer Options?

I, for one, had no luck with either SuperSu or addon su. The first would put the HD+ into a permanent boot loop necessitating a re-install from scratch,and the latter would install but the unit still indicated it was not rooted. Doing the Dev Op made no difference. A real mystery!

The file addonsu-14.1-arm.zip in the main folder is the one to use. As I seem to recall, you might have to enable, disable, then re-enable, in order for root access to take effect.

That is the one I flashed using 3.0.1.0 TWRP. Not clear on your second sentence: "...enable, disable,, then re-enable...". Forgive me for being lost as to what you physically/specifically mean. Please explain.

I meant "enable, disable,, then re-enable" the root access option in "Developer Options".

Aha! Will give it a go. Thanks.
5/2/2018:
Okay: I d/l three android root checkers and titanium backup. The first root checker (Clivin Inc. with small green android robot graphic) told me I was not rooted both before following your above instructions and after. The other two (d/l after following the above) both say I am rooted. However, I was not and am still not able to get "TB" to run. It says "failed" and that I am not rooted.
Since the HD+ is running really well now in its stripped down mode, I can "leave well enough alone" or try to get "TB" working so I can remove anything not needed for my chosen minimal functionality (ereader, viewing videos, photo review/minor editing) that would further reduce unnecessary battery drain.
Thanks again for the above clarification and any additional thoughts.

I am having this same problem
- Root options *do* appear in my Developer settings, but no amount of toggling on/off/on seems to enable root
- I have flashed the Lineage SU addon, log shows successful in TWRP but no change after boot
- SuperSU from Play Store says "SU Binary occupied"
- Adaway says "Rooted Android required- Either the su binary could not be found or you did not allow root permission for Adaway" ie I believe I am indeed *not* rooted.
- SuperSU flashable zip is a broken link on their website.... http://www.supersu.com/download
Out of ideas here, anyone got anything else I can try?
Edit: I was able to obtain Root properly by flashing Magisk & installing the Magisk Manager APK from here: https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445

You got it. Use Magisk. Works wonders and way better than SuperSU or any other root permission tool I've came across. It's even akin to, and even has within it, xposed and other magical rooted modules for you to try out for a day or two and then decide you don't need it.
