My nexus 7 had slowed down recently. So I was advised by someone here to reinstall the stock rom. So I backed everything up that was on it and installed the latest version of android (4.2.2). It worked. It's not slow anymore. But there's one problem. I can't delete any files on it using es file manager. I get a message saying "cannot delete some files. Please make sure that your storage is not mounted as read-only". I don't know what that means. Can someone help me?

You can delete unwanted files straight from TWRP Recovery. TWRP > Advanced > File Manager >SD Card > Select Items > Delete.
Well that worked. But it's too much trouble to have to go into TWRP just to delete a file. Why can't I delete it with ES file explorer like I could before I reinstalled the stock rom?

You don't state if you're rooted....
Yes it's been rooted.

And SU or SuperSU (whichever) is active, with root permissions being granted as needed?
Depending on where you're working you may need to ask for write and mount privileges through terminal.
For example if working in /system:
Code:
su
mount -o remount,rw /system
Caution do not do this if you are not experienced. You may damage your system.

Hmm I'm not sure I understand. I already put it in rw mode in the es file explorer app under tools/root explorer. But it still won't let me delete things.

Guys something is definitely not right. I just noticed that I can't read or write or edit text files (.txt). When I try to open a text file with es note editor it says an error occurred while trying to open file. Why is this happening? I almost wish I never did a fresh install.

Hm weird. Under the assumption that you are doing everything correctly, it should work as superuser permissions supersedes all and any limitation unless the file is open preventing it from being written to. If that's the case you will have to go through recovery as Username invalid suggested to edit the file.

I just tried that. Unfortunately it didn't work. And it gets worse. It seems like I can't do anything to the file system at all. Meaning I can't create a new file or folder. And I can't edit or delete what's already there. I haven't tried to download anything yet. But that probably won't work either. This is terrible.

If you can install apps, install root explorer from the store. Its the better tool for this type of issue. Also install terminal emulator and try the command that was in one of the replies above.
How did you return to stock?
Please don't fall back on the I'm a noob thing and expect people to hold your hand. The more you do/learn yourself, the better help you can expect here.

I returned to stock with the nexus 7 toolkit. It does everything for you. But it doesn't seem to help with this. Anyway I looked at those apps, and root explorer is $4.00. I don't mind paying for it. But I want to know if it's a necessity to have before I buy it.
The other app (terminal emulator) has multiple versions by different companies. How do I know which one to get? Here are some:
Android terminal emulator by jack palevich
Terminal emulator by cityapp
Shell terminal emulator by mobildev
Terminal IDE by Spartacus Rex
There are even more, those are the free ones.

So i have upgraded to the new r11 zimage and tried to install the latest modules but only some have copied over as others have copied but at 0k??
there are nine that will not copy over
Any ideas?
Enough free space?
Did you copy it using Android's USB mode? That tends to corrupt files, for installing modules I use Android Commander.
Yea plenty of free space others have copied fine. It's copying the file over but its empty 0k I'm using a root explorer to copy over as there are a few files to copy with this update

your trying to copy the files without root privileges.
in the term the first thing you need to do is type su
that will change the $ to a #
then copy the files.
cp /sdcard/*.ko /system/lib/modules
I shall try that but I wonder why some went over then but others did not

Make sure the system is rw. Otherwise it just "pretends" to delete.
Yeah apk sorry. Switched keyboarding. root explorer says r/w at the top

Don't trust root explorer. It doesnt always correctly mount as rw.
How do I fix that sir?
Sent from my SCH-I500 using XDA App
You can use terminal commands, but for a fairly simple way to do it, I use "Remount /system (ro/rw)". It's a free app on the market, easily remounts system as rw at the touch of a button.
Well my idea didn't work but thanks guys

Ok, never seen this before and suspect SD card corruption.
I did a nandroid backup today before I flashed a custom kernel. Everything went well. Now I am getting low space alerts (got the 8GB model). I want to delete the backup which comes in at 1.8GB. Problem is, the permissions are wacky - the folder perms are rwsrwsr-t (775 with set uid, set gid and sticky).
I can't delete or change permissions with either root explorer or from the shell as root!
Has anyone seen this before, or have a solution ?

Same here. No clue how to get rid of it.
This is what I did when I switched from CWM to TWRP
1. Get Root Explorer
2. Navigate to /data/media/clockworkmod/backup
3. Delete whatever backups

If I delete with root explorer I get "delete failed". If I adb shell in and `busybox rm -fR` I get "Operation not permitted"

Phonic posted a script in the "[RECOVERY] r3 (6.0.0.4) - Interim ClockworkMod recovery for Nexus 7" thread in the Android Dev forum,
when executed thru CWM will delete undeleteable backups
didnt use it myself, I used Solid Explorer to delete /data/media/clockworkmod/backup/......
Ok, I rebooted into recovery and was able to delete the files with adb shell.
wiithepeng: Sorry, didn't see the /data/media path at first glance, I was going straight to /sdcard - so it might have worked your way.
Thanks for the help.
No problem. Glad you delete those backups

Try THIS. Common problem and fixed in the newest version of the Recovery from that thread AND apparently the newest CWM directly from Koush.

Thanks bro... Root Explorer is premium so even ES File Explorer works as long as you are rooted and grant it SU access, which would be anyway as you have CWM.

I've seen apps that you have to "push" them to install them. What exactly does that mean and how do I do it?

You need to use adb on a computer the command would be
adb push nameofapp.apk /system/app/
Or
You can use a file manager with root access and copy the app to /system/app and fix permission to rw-r--r-- and reboot

Or, alternatively you can use Titanium Backup to do the job.

Well, I meant exactly like bobdarkside has just described. I think we might misunderstood you, because with TB you can only convert previously installed apks into system ones. So if you need to do it without installation go for adb or file manager method.

I have a bit of a problem here!
I got the ota update, wanted to install it, but failed.
So i downloaded the ota zip file from our site. ([REF] Nexus 7 Stock OTA URLs)
Went to recovery and tried to install it, and bam. Failed!
It says Something about xt9ime.apk not being in system/app or sth like that.
Can anyone help me?

You should have had a look at your log file or have been done the update while running logcat, in that case you would see the exact error message / the file the updater is complaining about.

The updater doesn't find XT9IME.apk on your /system partition. Due to that it's failing. If you have a copy of the file, try to install it in recovery mode to /system/app and try to apply the update again.
