Available space info in root explorer - Sony Ericsson Xperia Neo, Pro

Hi
I used to have the total and available space info available as shown in the attachment but now its gone all of the sudden...does anyone know how i can get it back?

Once I hade same problem, even though in preferences->info bar mode i set to show size it wasn't showing size.
Have you checked that setting?
How I solve problem? I think I reinstalled app.
Sorry for not giving the solution..

no need to apologize, mate....i also tried reinstalling but it does not fix the problem...

Meh, I don't remember what fixed it.. Maybe even clean rom install.. I just noticed one day that it works again
Don't know..
Try wiping cache and dalvik cache in recovery.. just a wild guess..
Do you remember what you did on phone lately?

Hi,
This is usually caused by a bad busybox binary. Root Explorer uses the df command from busybox to find used and free space. Other people who have reported the same problem have found that the df command in their busybox fails. You can confirm this yourself by entering a command such as "busybox df /system" (without the quotes) in a terminal emulator. If this is the problem then updating to a fully working busybox should get it working again.

[Q] How do I get SU in a terminal emulator?

Ok so some background, I am running the newest molten and enjoying it thouroughly but just noticed that when i open terminal emulator and type SU to get root access in the terminal it says permission denied and most other commands return same error, i downloaded a differant terminal emulator that checks for the su.bin and it shows no su binary is installed yet when i goto the directory system/bin/ in es file explorer su is indeed there?
Could someone please tell me why none of the terminal emulators are finding the superuser binary? I ve already tried opening superuser app and updating the su binary (it did update and i rebooted after) but it hasnt helped, I also read on other forums that there are multiple su binaries on some phones? could this be the problem and if so where would i find the right binaries?
It just seams odd that terminal emulator would be included in the build if it is completly unusable
su then hit enter
lol, thanks, im not the smartest with linux commands but i know to hit enter.
I tried typing su and hitting enter in 3 differant terminal emulators but keep getting permission denied in all of them
You should get a super user request once you hit enter. Maybe permission was already denied. Try clearing defaults for su.

Did you recent apply the 2.3.5 update? When I went from rooted 234 to 235 I lost root privileges even though the superuser app was still there.
Could be your root isnt quite right. What setup do you have. Also try going into your superuser application and see if they are on the not allowed list.
Also should go from a "$" to a "#" sign after you hit enter if su took.
thanks for the ideas, that really narrowed it down, i cleared data for superuser and terminal, reinstalled terminal, still didnt work.....then i realised im a idiot, my keyboards autocap was on and su has to be "su" not "SU"
lol well thanks again for all the help

[Q] Bricked with adb access, no root

So I bricked my Kinde Fire HDX by changing the build.prop and not fixing permissions. I have adb access but no root (I don't know why :S). Would a factory reset work? If not, how can I get to fix the build.prop or replace it with the old one? thank very much, I've been a couple hours looking for solution but I couldn't find any.
No, a factory reset would only break it further. It would remove your adb access and not fix anything. What makes you think you lost root? Have you tried "adb shell" then "su"?

I used the HDX ToolKit v0.92 to check the root access, and it said "Please grant root on your device"
I've also tried "adb shell", and then "su", but it just returns "su" again. I am new with adb commands so I don't really know what it should show.
Thank you very much for your help
May I ask what version you were on before you bricked?

Nope, I couldn't find any way to get root acces again. But nevermind, my new kindle fire will be here in two days. I am surprised how well amazon costumer service works. Even though I bought my kindle in the US and now I am in Spain (not going back), they called me from the US for free, and they are paying all the shipping costs and sending it by priority shipping.
I am still interested if anyone knows how to fix it, just for fun

It sounds like to me that you still root access you just were not mounted RW in other words it would not boot up completely so you could hit allow to the adb Shell. So you will have to mount system rw manually Try last 3 pages of this thread http://forum.xda-developers.com/showthread.php?t=2588608. He can fix you most likely if you can comprehend and follow directions.. or if ur understanding adb is fair you'll be able to probably extract your repair from the thread as is.

I've tried what it is said in the other thread. However, the problem there is that the guy cannot get his device to be recognized.
I've tried this:
adb root
adb shell
su
mount -o rw,remount /system *****- if this fails, try: mount -o remount /system
chmod 644 /system/build.prop
chown root.root /system/build.prop
reboot
But adb root gives me this error:
adbd cannot run as root in production builds
On the other hand if I skip the "adb root" step I cannot go further than "su" since I don't get the "[email protected]:/ #" line.

I'm not sure either that's why when I used it I was on a blacklisted unit and I kept the PC and the tablet and airplane mode at all times. Until I was certain I got all the files off of both before I let them go to Wi-Fi Chinese files that is.. But one thing I was very curious about is if you open that tool up the Chinese tool that is an you go to the same page you would hit the anchor to root to your device just below that it says fastboot I'm wondering if they have a fastboot working for also too bad nobody here know Chinese..

[HACK] Change System Status to 'Official' with only Busybox

Hi guys,
I found a method to change System Status in Odin mode to 'Official/Samsung' that is very simple and only using the busybox application "devmem". Use this command in adb shell or terminal emulator. Just type it in, hit enter, and reboot. Bam.
Code:
devmem 0xF91CF8C 32 0xFF000000
This will change your status to Official and remove the padlock with 'Custom' on it. If you want 'Custom', replace FF with EE.
Immediately upon reboot, Odin mode and the device recognize the device as official.
The explanation is that this is from a small region of memory that stores what's known as DDI data. I don't know what that means yet, but some other information like the CC Mode flag and device name/product number are stored here. I'm still doing further research on what else resides here.
Enjoy.
Seem that "DDI" can be either:
A "MAC-e header parameter" as specified HERE.
Data Description Indicator (DDI):
The DDI field identifies the logical channel, MAC-d flow and size of the MAC-d
PDUs concatenated into the 3GPP associated MAC-es PDU. The mapping between the
DDI values and the logical channel ID, MAC-d flow and PDU size is provided by
higher layers. The length of the DDI field is 6 bits. When, due to the
quantization in the transport block sizes that can be supported, the size of the
data plus header is less than the TB size originally selected by the E-TFC
selection entity minus 6 bits, the DDI value [111111] shall be appended at the
end of the MAC-e header to indicate that there are no more MAC-es PDUs
concatenated into this MAC-e PDU. In any other case it will be understood that
another MAC-es PDU would not fit and it will therefore not be necessary to
reserve room in the transport block for this additional DDI field.

I havent got it to work either. Though im guessing its only good til a reboot before it gets rewritten?
I thought I read in passing that syscope was the app that checked to see if the system was modified or not. I think it said if you get your phone to say official and freeze/uninstall syscope you won't have the padlock show up anymore.

Busybox is an app. It creates s series of links to commands that are typically available on a Linix (unix) system. Android kernel is linix based.
devmem is a command available in an adb shell or in terminal mode.
No idea if the hack still works or not.
If it does still work I am sure it would require root.

You just need devmem and the address. Not busybox devmem and the address.
The only thing I can suggest is that you use ODIN to flash back to whatever the latest stock ROM you were on and go through the rooting process all over again.
The bootloader won't allow you to boot with a non stock recovery unless you unlock the bootloader.

[Q] Installing X-posed on Archos 80G9 (Unofficial CM10.2): problem mounting /System

Hi
I've installed CM10.2 (last update) (http://forum.xda-developers.com/showthread.php?t=2499796) on my Archos 80G9. It also runs the SDE firmware from Archos (http://forum.xda-developers.com/showthread.php?t=1653566). So far, so good, it runs quite nicely, all things concerned. Here's a screenshot to the system info: https://www.dropbox.com/s/0ri8n4jb6gyrfz7/Screenshot_2014-11-17-20-56-01.png?dl=0
Now I'm trying to install X-posed Framework, but this won't work. When I try, I get an error that tells me /system can't be mounted. (Screenshot: https://www.dropbox.com/s/ryaryqkie023sl4/Screenshot_2014-11-17-20-40-16.png?dl=0 )
When I take a look is ES3 if the folder is mounted, it looks like this: https://www.dropbox.com/s/4kwv0ja16qz52tq/Screenshot_2014-11-17-20-49-21.png?dl=0 . I can't tick the other boxes here, I get the message "sorry, operation failed" when I try.
I've already tried to use the "mount -o remount,rw /" command, to no avail...
I have no idea how I have to fix this problem and if it's even fixable.
Does anyone have any idea? Thanks in advance!
Same here...
No solution for that yet.
Before you type the mount command did you type "su" first (without the quotes)?
Just opening up terminal gives you regular user permissions which will not let you run the mount command. You need to become root/superuser first and that's what su does.
Yes I did ... Terminal emulator gives a notification that It's been granted superuser permission, but it still doesn 't Work.

Can you send a screenshot of the "mount" comand and response?
Did the prompt change from $ to #? What was the output of "mount"?
If terminal doesn't work try with superuser adb (allow superuser not only from applications, but from adb). Connect to the device with "adb shell" and issue this command.
Hi, thanks for your response. Here are two screenshots: the first is of the mount command in Terminal Emulator, the second of the same via abd shell. No results.
Very strange, since filesystem seems to be remounted rw Ok.
In fact, I've installed xposed some two days ago on 101g9/cm10.2, so this should work.
Let's try to sort it out.
1) What version of xposed do you try to install? I've used latest stable (2.6 IIRC).
2) Do you use "standard" installation mode in xposed settings (just under the popup window on your screenshot)?
3) Try to issue the following commands in shell after remounting "/" (terminal or adb - doesn't matter)
# touch /system/bin/mytest.tmp
# ls -la /system/bin/mytest.tmp
If the file is created Ok, then the filesystem is mounted read-write correctly.
You can delete this file afterwards with
# rm /system/bin/mytest.tmp
4) Did you grant permanent or one-time superuser permission for xposed? If one-time, try permanent: it can be so, that "cp" fails due to lack of superuser permission.

1) I had 2.7 Experimental, so I uninstalled it and installed 2.6 Stable instead.
2) I do indeed use the "classical" option for installing Xposed.
3) Tried it, gave the following result: the file is created in /System/bin, so I guess /sytem is mounted okay. (see screenshots)
4) I use SuperSU, XPosed had root acces (see screenshot)
Seems to me /system is mounted fine, but Xposed just doesn't know it...
Ok.
The problem is with xposed, obviously.
For me, it complained that it can not remount /system (obviously), but then installed Ok.
So, what I would do
1) Check the filesystem mounts. May be, for some reason, you have /system mount (quite improbably, but nonetheless). Try in the terminal
# mount
It will show a list of all active mounts with the following format
[what is mounted] [where mounted] [blah-blah and stuff]
For example, from anothe device
/dev/block/platform/hi_mci.1/by-name/system /system ext4 ro,relatime,user_xattr,acl,barrier=1,data=ordered 0 0
You can see that something is mounted at "/system" readonly ("ro" attribute)
2) Check if the /system/bin/app_process.orig already exists
# ls -la /system/bin/app_process.orig
3) Try to use logcat to obtain info. That is tricky
a) On the PC issue command "adb logcat > logcat.txt"
b) Start xposed installer, try to install, get an error
c) on PC press Ctrl-C

Alright, did all of it.
1) Don't fully understand what is listed here, but in the first screenshot is the list of mounts.
2) Checked it, doesn't seem to exist, see second screenshot.
3) Logcat is attached.
Ok, it appears that I got the problem. Need a little time to think how to solve this.
The problem is rather technical. In newer androids supersu has isolated filesystem mounts for different processes.
It means that if you remount filesystem rw in one process, it (read-write-ness) is not accessible to the other process.
I have a little older cm10.2 build (for low-memory devices), perhaps, this was enforced later.

So you're saying there's a good chance that if I install version 22_12_2013-13_29_20 (which i was planning anyway), instead of the latest one, the problem could be fixed?
Hmm, I installed the previous version of CM10.2, the problem seems to be persisting...
I noticed something today. I can create and remove files in /system using the emulator. I can't however do this using ES3 file explorer, even though it has root access. I was trying to edit the build.prop file, but it wouldn't let me save my changes.
I then tried to copy a file to /system in es3, this didn't work. Creating a tmp file using emulator did work. Seems I do have rw access to /system, but not with all apps...

Well, it seems like what I've said, filesystem mount encapsulation.
I've noticed one thing - you are using the standalone supersu application. And for me superuser mode is integrated in the system settings near the developer options. May be this is the case, internal superuser is patched already.
Alright, I'll uninstall superSU for now, give it a go with the built-in superuser app. I'll let you know!
Supersu application, theoretically, could have replaced libsuperuser and other stuff integrated in the CM.
So, if just uninstalling does not work, perhaps it will make sense to reinstall CM itself.
P.S. I have mixed feelings with CM. On the one hand it is definitely more fluid, than 3.* or 4.* stock ROMs. On the other hand deep sleep works, well, strange, and the tablet sometimes freezes in the sleep or turns off by itself.
Yes, I have enabled deep sleep, but the battery drains definitely faster in the sleep. For me it is essential, since I mostly use it as a amazon kindle / google books / pdf reader terminal. And most of the time it just sleeps.

Eureka! I re-installed CM, issued the mount-command i used earlier and installed X-posed! I used the built-in superuser app, no such problems as before. I did have to issue the mount-command, but that isn't a problem Is it normal I have to re-issue the mount-command each time I want to access /system rw?
Thanks a million! I can't believe it was something this trivial But I'm so glad it's solved, thanks!

I don't use the deepsleep-option. I do use Greenify to ensure certain apps (like Youtube or Chrome) aren't active in the background. Boot manager to be sure only essential apps boot in the first place. This seems to save me some battery life. Airplane mode as well.
I got this tablet from my dad because it was so slow he couldn't work with it. Even after factory reset, it very quickly became sluggish again. With CM, it feels like it's a new tablet. So no doubts about CM for me
I do have another issue: My pc won't show the tablet in explorer. I can access it via ADB, but I can't access the storage via explorer... I suppose I best start a new topic for that...
Glad the issue was solved. I wonder why the superuser application didn't work.. Deepsleep - it allowed the tablet to lose, say, 10-15% charge during a week sleep. Very handy if the tablet is used not often - really miss it.
Explorer connection - if I remeber correctly, you should go to settings -> storage (where the size of apps/pictures etc is shown). Then press the three dots in the upper right corner, select "usb computer connection" and select MTP.
P.S. I wonder also if CM12/Android 5.0 in the "development" section is worth a try...

[Q] /system is read-only

Hi
I've unlocked and rooted my phone. Everything works fine, except one little thing. The system partition is still read-only.. I have tried "# mount -o rw,remount /system" in adb on computer and terminal on the phone, but I get an error saying that the operation is not permitted. I find this wery odd, because I have granted superuser permissions. Also, when i type the command "adb devices", there is an empty list. Any suggestions?
Also, I can't install busybox.. Getting an error saying it failed, if anyone know how to fix this too, i will be wery greatfull

This is because of a protection called Sony RIC. You can find some solutions if you make a search.
