Phone: pixel 6a (bluejay)
I wanted to add more swap to my phone, out of curiosity, experimenting.
At last I found an app that worked, called "Ultra Ram Swapper" in Play Store.
I was able to add swap with it. I wanted to disable the big 8GB file I made, and use several smaller files.
But here is the problem: I cannot delete ANY swap file that Ultra Ram Swapper has created.
I get the same error. I can try from Termux, I can try Solid Explorer, Total Commander. All the same.
And what is this error? It looks like some kind of Java error?
I am a bit lost and confused about what the hecc is happening.
Any help is appreciated.
This is the error.
Update:
I was able to reduce their size to "0" with "dd", like so:
dd if=/dev/null of=/sdcard/.../ultraswap0
I also tried "unlink" tool but no dice.
The error gets originated by rm command, not by su

Oh yeah, it's just how Total Commander writes it. But "unlink" doesn't work either.

Thank you, this was it.

I didn't see a thread for this anywhere and it's not included in the rooting documentation so i figured I'd make one.
This will allow you to install apk files directly from the device, no need to adb them over. Just get the apk from the web or whatever source you want and install. Of course this is all assuming you have completed the current root process and have adb access already.
Thanks to godsfilth for finding these directions for the origninal nook.
1. Open a command prompt and navigate to your sdk tools folder
2. Run the following commands
Code:
C:\android-sdk-windows\tools>adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
C:\android-sdk-windows\tools>sqlite3 settings.db
sqlite> update secure set value=1 where name='install_non_market_apps';
sqlite> .q
C:\android-sdk-windows\tools>adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
3. Reboot
4. Install apps from NC without ADB.
You might have to restart your homescreen for the apps to show up, but i've had sucess with every app i've tried that is known working on the NC.
This was done on a Windows 7 x64 machine, although i'm sure it's the same or similiar for Linux and MUC OSx.
Also, sqlite3.exe was already in my sdk tools folder, if it's not for you then you can download from here.
Yep, and you can ADB install a file manager app, then just use the file manager to install anything else, from the SD card.

So...the nook doesn't stop apps from deing installed if Iinstall them manger astro file Manger?
What is the command in sqllite to see if the db entry has been changed?
I copied & pasted your commands and after a reboot still get "Can't install downloaded apk"
I did the same - even adapted the commands because the folder name wasn't the same, etc.
However, I'm trying to use SlideMe to install APKs and it keeps coming up with "Install Blocked" - any ideas?

Once you enable this it will allow you to install the apps, it doesn't have anything to do with astro per se. You can just use astro to navigate to apks stored on your sd card. I use estrongs file manager myself and have installed apks from my sd card, dropbox and downloads from dolphin browser hd.
I'm getting the same error as everyone else.
I made the edits per your first post and pushed the file back to the NC. Then I rebooted. Placed an apk in the NC and tried to open it using Root Explorer. I try to install it and I get the "Installation of donwload apks is not supported" error.

Slideme works perfect for me so you did something wrong. Not sure what though, I would just redo it.

just use
Code:
sqlite3 settings.db ".dump"
and then scroll down and look for INSERT INTO "secure" VALUES(4,'install_non_market_apps','1'); you want a 1 there at the end.

look in your tools folder for the settings.db file and check the modified by time and make sure the change you are making is made.
To clarify if there's a misunderstanding the path info and text before the > in the commands is just what you would see in your command prompt. the actual commands are after the >. These are the actual commands.
Code:
adb pull /data/data/com.android.providers.settings/databases/settings.db settings.db
sqlite3 settings.db
update secure set value=1 where name='install_non_market_apps';
.q
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
What command did you have to alter?
also, maybe try
Code:
adb push settings.db /data/data/com.android.providers.settings/databases/settings.db
to push... I didn't have any problem with the other command and both appear to work for me.
Oh none, your commands worked awesomely, I just had to yank the folder designations that were there, which you've now done for everyone, so thanks!
I think it might be a problem somewhere else, I'm re-doing everything right now, I'll let everyone know
Ran these commands again with the additional adb push and still no dice. I checked to see that the db entry had been updated and it correctly has the install non market apps set to 1. I'm using root explorer as well I'll try estrongs as you have. Thanks for the help.

Confirmed now that SlideMe is not the issue - the settings are all correct on the PC, I can't confirm these settings for the NC. I tried re-adb-pushing and still no cigar here either. I'm getting app rejections from any source, downloaded on the NC and the SD card. Any idea what could be wrong?
Ok, definitely isolated the problem now.
I pull the settings from the NC, modify them, and everything works great, then it refuses to push it back, but says it succeeds, or something to this effect, because whenever I pull the file back from the NC, it says value=0

Not sure, I've got it working using this method on 3 different NCs myself. The only thing i can think of is that i had already installed estrongs file manager and a few other games before doing it. Maybe try using adb to install estrongs or astro and see if it will let you then.
estrongs i'm using: www mediafire com ?sxw6adfzvyp250m
astro: www mediafire com ?05scsbrnx2wfw4v

Thanks for the file links - I'll give them a try, I really think the problem though is that the NC keeps resetting the value I push back for the non-market apps. I have no idea why it's doing this...

try pulling it back right after pushing the modified one, before rebooting, and see if it's even pushing correctly at all. If it is then being reset on reboot i don't know what the issue is.
Novaglarion, I am not able to do it either.
When you say "reboot", is that the same as power off and on?

yes, the same.
make sure you're pushing the modified db file to /data/data/com.android.providers.settings/databases not to /data/data/com.android.providers.settings
it needs to be in the databases folder so it overwrites the original

Hi,
I tried to edit the file "state" in "/sys/devices/virtual/switch/hdmi/" to unlock HDMI checking according to some internet posts I found. The problem is that it won't let me edit the file. I used Root explorer. My phone is rooted.
I also tried using Terminal emulator + Busybox to directly edit the file but it still didn't work. The file can be copied to other directory, and the copied file in the new directory can be edited, but the original file cannot be deleted or edited. When I tried to delete it, the message showed "Operation not permitted".
Any idea? Do I have to use "mount" command ? If so, please suggest. I am new to android and linux.

Hi, I'm using an LG Optimus L9 and running 4.3 bassed PAC-man rom.
The internal memory is 4GB and after installing a few apps, I started getting "Not enough storage space" warnings.
So, I checked the /data folder and found that there's directory called lost+found which is taking up a lot of space (Above 1.5GB).
I tried deleting files using ES Explorer with the data folder mounted as R+W, but it says "error deleting files"
Is it safe to delete the lost+found folder?
And if yes, how can I delete it since I'm unable to delete it with a file explorer app.
It would be really great if could recover thelost internal memory

Using TWRP.
If I backup first, it will also back up the lost+found data
And restoring data will bring it back.
I did format data and system before flashing the rom. So I don't know why the lost+found has so large size.
What should I do?

hmm, i'll try flashing CWM and then do a format of every partition and freshly flash the rom.
Will report back if there's the same problem.
UPDATE:
Formatted all the partitions including /data/media using CWM
Did a fresh install of rom.
I've got my internal memory back
Thanks!
my 2 cents...
my 2 cents... I've opened the lost+found folder with the file manager (this https://play.google.com/store/apps/details?id=com.rhmsoft.fm), after enabling the root explorer functionality, and deleted a bunch of the biggest files, just checking they were at least 2-3 months old. Rebooted to make sure everything is fine and dandy, and now I've got enough free space, sun is chirping, birds are shining, life is beautiful :silly: :victory:

I was having the same problem. My phone is Samsung Galaxy S2 (GT-i9100). I was on stock Jellybean. But it was starting to feel sluggish and slow. So, having heard about the new Android Kitkat's lower memory requirements and smoother performance, i decided to install Cyanogenmod 11 on it.
Installation was not without problems. At first i flashed Clockworkmod Recovery 6.0.2.9. The phone bricked into a bootloop with a yellow triangle on it. Flashing the Cyanogenmod 11 resulted an error of "Status 7". So i searched for the latest Clockworkmod Recovery, which was at 6.0.4.5. After flashing the 6.0.4.5, Cyanogenmod 11 installed successfully. Performance was really smooth. No lags, no jitter, and everything worked like a charm.
The problem started when i re-installed my applications. Suddenly i got a message of "insufficient storage". This has never happened before. Note, that i previously had large games on my phone like Real Racing 3 and Bard's Tale. This time, i haven't even installed those large games. So i looked at my Storage, and found out that i only had 141mb of free space. But the weird thing is, my reported Apps was only 353mb, from 1.97GB internal storage. So there was over 1GB of storage just vanished.
I browsed for a solution to this problem, and landed on this thread. After reading reply from fabiosirigu, i decided to brave myself, and deleted the content of the lost+found folder (but not the folder itself). I accessed the folder with the built-in File Manager from Cyanogenmod, and set it to "Root Access Mode", and select all folder in the folder, and deleted it. The deletion took quite a few minutes, which felt like ages. Just sat on my bed, crossed my fingers, hoped that nothing will go wrong.
After the deletion, i rebooted my phone. the cyanogenmod logo appeared, and the system booted as usual. I just exhaled a massive sigh of relieve. I went straight to the internal storage, and now it is showing the correct report, 1.67GB of free space.
Thank you for your reply fabiosirigu. Really solved my problem.
lost+found genesis
Let somebody correct me if I'am wrong.
lost+found directory is standard for some unix/linux filesystems. All ext(s) 2, 3 and 4 contains it by default.
The operating system collects unidentified, broken files and its parts inside of l+f dir.
No one of these junks is used by running system.
So - you can look in l+f for some lost, missing files. If you don't miss for any (who knows it better?) then you don't need l+f content.
Unhappy [Q] Problems with deleting files and replacing sounds
HI all! New use here.
I superuser'd my phone, routed my phone, installed CM11 and all is well. It was my understanding that with apps like RootBrowser and or SuperManager i could browse to files change permissions and delete and remove them or replace them.
I am unable to change my lock sound or boot animation.
Ive granted the permissions to the apps and am operating the root browsers in Root mode. (sorry if my terminology is wrong but im new to this) When i try to replace the files in system/media or system/media/audio/ui they simply dont work, "operation failed". I am able to change the permissions on the replacement files going into these directories to match those im overwriting but its still fails.
Ive even successfully deleted the default lock sound but when i paste the new one into the folder it fails and says stuff like "out of space" or "no room" and then when i shut app and go back in the original file is back!
Can anyone help with this as my lovely rooted phone is being very difficult.
Your partition is mounted as read-only, that`s why you get "operation failed".
Mount it as read / write and should be ok.

When i use the app SuperManager to browse the file system to "system" folder it asks me "If you want to modify the file in teh system, you have to mount the system image first. Please choose access mode: System IMage: R/O"
then
"Do nothing Read only R/W" so i chose R/W but that does not fix the problem?
My errors i get are "not enough free space" well there is plenty of that!
So confused....
Any thoughts
Just ignore the "not enough free space".
Cant help you with RootBrowser or SuperManager because I never used them. I use ES File Explorer, and mounting partitions with it always solved my problems with not being able to delete / modify system files / apps.
Hello guys, new user here, so please exuse me for any mistakes I made (posted in different thread for example). So recently I finally managed to root my Lollipop Sony Xperia Z2 (D6503). I decided to make a backup of my current rom using ROM Manager, so I did so. I chose it, then my phone restarted into recovery and did the backup. When I went back to the OS, I saw that I hadn't any space available left on the phone's internal storage. I found the folder clockworkmod/backup/(name of the backup) and I deleted it, but no space got freed. I found out that after android 4.1 it doesn't actually save it on the sdcard but on: /mnt/shell/emulated/clockworkmod/backup/(name of backup). I tried deleting the folder using Total Commander, but every time I was trying to delete it was giving me a: "Permission Denied" message, so I decided to try and change its permissions. It said that: "Function Succeeded!". but still no luck, and the permissions actually didn't change. Any suggestions anyone could give me? It has been getting on nerves lately because it seems that there is not way to delete it. Thanks in advance.

Nope, still the same. Tried with ES Explorer, root checked, granting superuser, but still, when I go to delete it it says: "Permission Denied". And yes, it is read/write.
