[Q] Busybox Normal Install Failed - su not found, phone has been unrooted.

Hi Guys!
Newbie here. I have root my phone I have installed busybox from Google Play. I want to update my busybox to 1.21 so I installed it. I have launched the application and then clicked install. I have chosen "Normal" for normal installation. Then I tried installing the busybox into "/sdcard/busyboxfree/" to see if it would run so I entered "/sdcard/busyboxfree/" to the installation path after selecting "Normal" rather than "Smart". And then an error occured saying my su binary was not found. And then I tried opening a adb session and typed "su" (screenshot attached). I can see the SU app grant superuser permission for adb but the adb shell got stucked (see screenshot). So I tried navigating to /system/bin/ and /system/xbin/ to search for the su binary but I can't find it. I also lost some sh commands like "ls" and "rm" so I am using the busybox to do those commands. I can use the busybox so I suppose it is still in my system.
I have done some restoration such as Factory reset / Wipe Data, and restoring userdata using recovery mode (I don't have CWM so stock recovery). And then I tried rooting it again using the same process I have made rooting it before but now it is not working, I can't get the root back. So I decided to ask the huge developer community and experts to consult what to do about this. :victory:
But I have followed instructions from a post at XDA. I have dumped the mtd6 "recovery" and mtd11 "system" before I did the busybox installation (see screenshot mtd.png). Is this enough to restore things back? How do I flash these dumped images? I will be attaching a link to download the dumped images.
My question is, is there a way to gain SU permissions (root)? Do I just need to push/replace/configure/etc binaries or files? Any help will be appreciated. Thanks!

[Completed] CM11s install SU

Hello Gentlemen's
I am having One Plus One A0001
I need to install SU on it , but i cant install Update SU.zip from Cyanogen Recovery
(there were 4-5 option's)
{
1. Reboot
2. Apply Update
3. Wipe Disk/Factory Reset
4 .Wipe Caches
5. Wipe Media
}
When i tried to install SU from Apply Update
It was giving me signature error .
So please you people help me?
I get this information from this forum
Code:
You can s-off and after it gets root and you have s-off, (after you run revone -s 0) then:
Code:
adb remount
adb push su /system/xbin/su
adb shell chmod 04755 /system/xbin/su
Then you just simply install the SuperUser app from the playstore.
I was not able to understand any of this ,
So Please help me to install SU as i need root access for a particular app.
PS:
I dont want to install Custom Recovery , as i want to keep like it only .
Thank You Very Much

Hi
Thanks for writing to us at XDA Assist. You can't install SU from the CM recovery because the CM recovery can only install zips signed by CM. In order to root your phone you need to do this:
1. Unlock the bootloader.
2. Install a custom recovery.
3. Use TWRP recovery to install SuperSU.
I put together a guide specifically for this phone which is very detailed and will explain all you need to know, you'll find it here:
[GUIDES][Q&A]How-To Guides For Beginners + Q&A
Good luck, and if you have any questions please don't hesitate to ask in the guide thread.

Firstly Thank You for your valuable reply .
So we can't push files manually in /system/bin like locations ?
After reading deeply about rooting and what is actually does , I understand that twrp just pushes files for us that busybox and Superuser.apk in read-only file systems which cant be accessed by side-load or MTP's .That UPDATE-SuperSU-v2.46.zip it is a universal kind of rooter, it is having all kind of files for rooting almost all kind of phone with different architecture's.
My Point is cant we manually push those files by adb interface in USB debugging mode , by SDK's or other command-line executable ?
and my issues are in those method's like ./psneutor is not working for me

No you can't just push it. The way to root this phone is how I outlined it above. Is there a reason you don't want to unlock your bootloader?

[Q] Can't root SYH WP800 android phone

I bought New SYH WP800 android phone,
running android 4.4.4,processor is MTK6572,
My phone has su binary file in /system/xbin/ but not in /system/bin/
All of root required application can't access su binary file, like es file explore, super user app, ROM tools box.
I tried to root but all of root tools said "Your device is already root, unroot?", but I can't unroot.
Then I tried in terminal and adb , "cp /system/xbin/su /system/bin/" but can't, error shown "Read-only file system".
"rm /system/xbin/su" can't work, too.
Finally, I tried with MTK droid tools, still not work!
Help me please! :crying:
very sorry for my bad english! I hope you will know what I mean!
Thanks everyone!

SU request hangs after root attempt

Hello world,
I try to make something useful out of my Samsung Galaxy Note 10.1 (GT-n8020), so I've started with reinitializing the device with kies, which got me a fresh android kitkat 4.4.2 rom (build: KOT49H.N8020XXUDNI2). After that, I wanted to flash supersu, of course - I've used chainfires cf-autoroot (CF-Auto-Root-p4notelte-p4noteltexx-gtn8020.zip - cant post links, sorry)
I've also flashed philz recovery which works quite well, over odin.
The problem for now is, I cant use the super user binary:
1. The binary was successfully flashed via odin on the device, like the supersu apk. Opening the app just displays a missing su binary, any other app which requires root cant locate or call the file...
2. The following permissions are set on the su file
[email protected]:/ $ ls -la /system/xbin/su
-rwsr-sr-x root root 96144 2015-09-15 14:44 su
3. I've enabled usb debugging because people like to use magic even if this has nothing to do with the main problem
4. I've tried to execute su via adb shell, but it just hangs.
So if anyone could help, I'd be pretty happy - if not, I'm going to throw this f*ck!ng piece of plastic into the woods.

Alright, using N8020-CWM-6.0.2.8-Darkman.tar.md5 as recovery and CF-Auto-Root-p4notelte-p4noteltexx-gtn8020.tar.md5 as root finally worked.

Next time you'll need to delete security log agent apk in system/app.
Now to unbrick you'll have to reflash stock, go to sammobile and find your firmware there.

Thankk you alot i tried it and it worked
