Root Error (489) downloading Apps & E: unable to mount /cache (Invalid argument)

- Symptoms:

Unable to download anything from app store.
error is: "<name of app>" could not be downloaded due to an error. (489)

Through the power of teh googles, I learned this was an issue with the /cache partition, so I booted the phone into recovery mode in order to wipe the cache.

There is an error that displays in recovery:

E: failed to mount /cache (Invalid argument)
E: can't mount /cache/recovery/log
E: can't open /cache/recovery/log

This error repeats itself on the screen.



- Things I have attempted to do to fix this:

1. wipe cache partition
RESULT: Says wiping cache partition, then the same errors repeat on the screen.

2. Wipe /data and /cache partition (factory reset)
RESULT: Begins to wipe partitions, then says it failed, and the same errors appear on the screen

3. Used the handy instructions, Odin, and the new CWM you lovely people have written up on these forums to attempt to root phone (Installation failed) - same errors

4. Attempted to flash a new, modded ROM hoping it would repartition the memory (Installation failed)

5. Attempted to flash with the stock ROM and recovery (Installation failed - same errors)

I've attempted this both with and without the SD card, and with a completely different SD card.

The phone still works. It still boots, it still loads the same ROM it has always had, still has all the settings and data it had before (data wipe didn't happen, it seems), and can make and recieve phone calls and connect to the internets.

It just cannot download any new apps, or update any existing ones. I'm at my wit's end, and considering replacing the phone completely, it just feels that since so many other things are just fine for this device, even if the /cache partition is corrupted, there should be some way to repartition it, or reformat it so that it can be used once more to its full capacity.

Any help at all is appreciated!!

Thanks!
 
Thanks for the reply!

I knew I forgot to include one of the things I've tried; clearing the app store cache was one of the 1st things I tried, in addition to also uninstalling Google Play (so it reverted back to a previous version of the app store).

Those were two things I found on my search of forums for the initial error in the app store.
 
Hey guys, I've moved your thread over/up-to the all-things-root area in hopes that the folks here can give some more helpful suggestions.

Best of luck with this, bekito--I'll be interested to hear what the resolution is.

:)
 
Thanks scary.

Now I have worked side by side with most of the people on here for over a year now. There are great people here. Please be patient. Someone will answer. For the life of me, I am drawing a blank.
 
Just did a quick Google search for "samsung error 489"...while it appears to happen more frequently on Samsung devices, it seems it's an Android problem in general (someone was having the same issue on a Motorola Droid RAZR).

Anyway, getting back on track...I apologize if you've already tried any and all of the following suggestions, but this seems to be the common consensus on how to fix the issue (with my own twist on things):

1. Go to "Settings > All apps", go to any and all Google apps you have installed (Google Play store, Play Music, Youtube, G(oogle) Talk, Google Services Framework, etc.), and clear the data (which will also clear the cache in the process).

2. Assuming CWM is still installed on the phone, reboot into recovery, and clear the Dalvik cache (from CWM's main menu, go down to "advanced > Wipe Dalvik cache > Yes, Wipe Dalvik"), then reboot the phone (from advanced menu, select "Go Back > reboot system"). If CWM isn't still on the phone, then just reboot it.

3. Once the phone has booted up, open the Play store, and try downloading an app or app update. You may have to (re-)enter your gmail account, accept the Play store's agreement, or something like that (whatever stuff you usually have to do when opening the Play Store app for the first time).


If that doesn't work, also add "Downloads" and any and all browsers you have installed on the phone to the list of apps to clear data on. And if that doesn't work, then I'm lost as well. :p The only other suggestion I can make is if you've gotten this far and still haven't figured it out, then maybe something's wrong with the hardware that's keeping the software from functioning properly. Past experiences have taught me that the two are more interlinked than we tend to realize until something goes wrong. :rolleyes:
 
hmmm that is odd. Ive had the same problem before i did the whole wiping the cache and the app data clearing in system settings and that fixed it. I actually have to do it a cpl times, so i know the solutions you tried work which puzzles me. Im kinda curious to the problems you are having in cwm installation of roms and wiping not working. Sounds to me cwm is corrupted or broken for you. I know youve tried to re odin cwm but try again cuz sometimes odin can be pain in ass.
