so why do we even need to wipe it than?

Dalvik cache isn't on that directory that has the error. Its a seperate section that still gets wiped. The other directory would probably have something to do with it if it existed. In any case just ignore it

App problem

Hey guys, I have a problem when installing new apps or doing updates.
When I try to install new apps (angry birds Rio) it will download but not install, it has done this on other apps too. I have deleted apps to make room and done a factory reset and its still not working.
Any ideas?
Thanks

Have you tried to wipe the marked data from application settings? Don't know if it's going to help, but it's no harm in trying
Does it give you an error message when it gets to the install process? You could try unmounting the SD card temporarily before you try installing apps, this solved the only problem I've had installing apps from the Market.

Hope this helps

Settings - applications - all aplications, locate marked and wipe all the data. Next time you start marked you should have to agree with terms as you did the first time.
Tried that mate, still not working

I've had this happen in the past and the only way I could get around this issue was to delete the file 'Smdl2tmp1.asec'
To do this, connect your phone to a PC and use Windows Explorer to search for the file. You will need to set Windows Explorer to read hidden files for it to find this file.
Hope this works for you too.

If the apps download but don't install you can install them manually. Using any file manager head to /cache/download , here you will see all the apps you tried installing recently. They don't have useful names but the icons should help you remember what they are.
Find the package and install it manually.

Right I sorted it. I took out the sd card and it installed it for some reason

[Q] HELP!!! Can't get my Droid2 to flash CM7

So I backed up my stock Rom, restored and cleared cache. Now when i install zip from sd card and choose the zip i want from sd card and click yes to flash it. I get this error message.
E: Error in /sdcard/update-cm-7.0.3-droid-signed.zip
(status) 7
Installation aborted.
Can someone tell me what this means and how do i fix this so i can flash CM7, I'm getting very frustrated.
You need to format your system, cache, and data. And you also need to be using the right kernel.
Look on rootz wiki for cm4dx. This is essentially how you need to prepare, except use D2 files instead (A Google search should help you with it)

Thanks, I checked the site out but didn't really understand most of it. Do they have a tutorial or a video on how to do that on there site. Would you be able to copy the link on here. I'm not very familiar with that kernel ****. I really want RM7 but don't want to mess **** up.

And reboot
Then,
try installing the app "cachemate for root users"
from the market, check power clear option, and clear cache
Then try running rom manager, if it still doesnt work, try uninstalling and reinstalling

I get something similar. Also, after doing the full root, I lose root after a reboot...and even after I have root...no root commands work.

Getting Force Closes? Try this.

Just learned this today actually Figured I might as well share. Applications often keep a large cache under /data/data/. Unfortunately many of them do not provide a way to clear the cache without clearing at the same the configuration parameters for the app. (You can clear the whole data in Settings->Applications->Manage applications.)
Using ADB... In terminal emulator or whatever type this command:
df datadata
Click to expand...
Click to collapse
If there's barely any free space that's your cause of your force closes. An easy way to fix that would be to go through your apps and clear all the data/cache.
You can find which applications use most space with:
du -sk /data/data/* | sort -rn | head

Also there's an app called Cache Cleaner NG. Clears all your app cache for you
Excellent post!
Has anyone seen John Connor?
Does clearing cache and delvik in cwm do the same?

Tried this out as I'm having really poor performance using the Twitter app on Super Clean ROM , but alas, 1 GB free. Should be more than enough.

Wifi problem

Well anytime I use stock rom the wifi wont connect. And when I was unrooted it still wourent connect. Im using royal glacier n I like it but wifi cant connect, only when im close to the wifi router it does.but miui and sense roms connect perfectly and being far away. Ive use apps like wifi fix and stuff from market and still wont work. And I googled build prop wifi fix and dirent find answer. Ands its not the kernel cause ive used a stock rom with tdj kernel...so my question is how can I make it work? And my problem is only with stock roms. Any way with the build prop or an app or tweak? And it connects only when im next to router but disables when im more away. Thanks

Try these steps:
Restart the router by unplugging for 10 seconds and then powering it back on again. (I'm assuming it's not a router issue but sometimes this can simply be the cause)
This may be a bug in the ROM or an error during the installation, so I would re-download the ROM, verify the MD5 sum.
In CWM, backup the current ROM. Do a factory data reset, wipe cache and dalvik cache, go to mounts and storage and format /system. (this is to ensure there aren't any files lingering on the phone)
Flash the ROM, and after the flash wipe cache and dalvik cache (just in case.) Reboot.
If you're still experiencing WiFi issues it's most likely is a bug in the ROM and I would contact the developer of the ROM for a fix/workaround.
If you want to try, you can download the Kick Ass Kernelizer script by Zepplinrox found here:
Kick Ass Kernelizer RC7
After you have the script on your phone, install script manager from the market, err, play store
Navigate to the Kick Ass Kernelizer script and tap it. On the dialogue the pops up click 'run as root' and run the script.
Follow the on-screen instructions and choose if you want I/O tweaks.
After this, in order to make sure the script runs, there should be a log somewhere that would tell you
If it isn't running from your init.d folder you may have to navigate to your init.d folder at /system/etc/init.d
Find the script usually 98 something Kernelizer. Click it and select Run at boot as well as run as root. This should fix that issue if it's not running.
And if the kernel tweaks there don't help you, it's a bug. Contact the developer or switch to a different ROM
Wow thanks for all that help!
