system R/W problem after 4.3 update. please help - Nexus 7 Q&A, Help & Troubleshooting

I updated to JB 4.3 via adb/fast boot and everything went smooth. The only issue I'm having is that when setting up ROM toolbox ad blocker I'm getting an error can't mount system read/write after the host file is downloaded. I installed busy box beforehand and had no problems mounting the system r/w there and also able to mount r/w inside es file explorer. Anyone have any idea what's going on...I'm I missing something?

Did you root ? Which method ? Flash chainfires binary .

Yea, I rooted. I used a version of super su that is recommended for JB 4.3. I updated the su binaries. There's something keeping the ad blocker from mounting r/w on the / I decided to go back to 4.2.2 for now. I was having another issue with 4.3... I couldn't uninstall the stock launcher through titanium backup. When I tried it said the system apk couldn't be located. I didnt really notice much to speak of in the way of new features in 4.3

Your lagfix whatever it is , is screwed. Betcha have problems installing apps too. You need to clean install rom again. I noticed the problem after I installed new kernel forgetting to disable lagfix before update.

[GUIDE] Update Superuser From Market FIX!

I am running LeeDrOiD, but I know many people have this issue.
If you are trying to update Superuser from the market, and you get invalid signature and installation fails. This is my work around, which works for me.
My rom had superuser.apk and not Superuser.apk, which linux takes as two files whilst windows references everything in capitals.
Download Superuser Update Fixer.
Run the application, which will say that signature fails. Then run the fix, which will say okay all the way through and the signature still fails.
Download Root Explorer, and mount /system/ as rw.
Go to /system/apps/ and you will find Superuser.apk and superuser.apk, rename or delete superuser.apk and then rename Superuser.apk to superuser.apk.
Restart your phone.
Go to app drawer, and launch Superuser. Your whitelist and blacklist has been erased.
Run Superuser Update Fixer and you should see signature match is okay, now click update from market and enjoy.

I don't think there is. There may be another app that does this job though. You need something that can mount system rw.
It may be possible to do this step with ADB, however I just posted how I did it.
ES file explorer has this system rw option, it says that it only works with CM and some other rom but it works for me and I'm running leedroid. Only problem is you have to unmount and mount it again every now and then.
Yeah to make it work just select the non CM7 mod option, HIAPK i think it's called? either way just select that one, apart from what the guy above me said about the remounting every now and then, should be a good substitute for root explorer
I downloaded superuser from market and the fix but wen using es explorer i only see one superuser?

I only have the Superuser.apk, but still have problems on the update. I had lost root and just decided to reroot, but got the Ninja Icon app. I tried to update - sig failed. Tried the Update Fixer and on changing to 644 fail, check sigs fail. Then I tried this.
Any other ideas on how to get it?
Wat rom u using?

[Q] Read/Write filesystem after rooted

I'm on stock rooted MDL and I can't seem to put my filesystem into read/write. I have tried ES explorer, Solid explorer, and even tried the remount rw command in Terminal Emulator. No joy.
Anyone come across this our have an idea? Haven't tried adb copy yet.

I am also having a similar problem, I just rooted my S4(SPH-L720) running 4.3 MK2(Stock Recovery and ROM) with CF-Auto-Root and when i try to use "SystemApp Remover" it shows system as not mounted. If I use Root File Manager I can change it to R/W and do whatever. But other then that I can not get /system mounted with R/W.

Meh, I couldn't figure it out and never found anything on it. Ended up flashing (Odin) a rooted Stock ROM (4.3 MK2) with philz recovery.
I wanted to keep my phone as close to stock as possible and just have root but inevitably I always go to a custom ROM. So my middle ground was the rooted stock ROM and I've had no issues so far.

[Q] Cant Change Root files on PA 3.99 RC2

So i just installed PA3.99 RC2 and then wanted to change the boot animation. I downloaded the .zip file and then had to paste in in /system/media/. I tried using root browser, ES file manager and File Manager. Using root browser, when i paste the .zip in the folder, i get an 'Operation Failed'. When i use File Manager, the 'paste' option is grayed out and cant be used. When i use ES file manager, it gives an error saying its 'read only'.
I also tried pushing the file using adb but that fails too. the error is "Read-only file system"
Is there any other way of pasting the .zip in the /system/media/ or /data/local/ folder?
I didnt try it on PA3.99 RC1 because i had issues with the rom using Franco's kernel
But there were no problems in pasting the .zip on the PA3.99 and thats why i reverted back.
Is there anyone else facing the same problem? cant paste files in the root directory? Is there a fix or workaround?
Thanks
Currently I am using PA 3.99 with Franco's kernel r184
Sounds like your root is broken. There are several posts in the PA thread that address this.

But I'm able to give superuser access to apps like root browser and Franco kernel updater. I don't think that's possible without root

Try removing one of the apps from your superuser and adding it back in. That should let you know if you still have root.
