How to Clear/Wipe Dalvik-Cache via ADB?

Hassan_Elyas · Dec 22, 2013

I recently got my cache corrupted and whenever i turn on the phone the phone goes into recovery and says -
E : failed to mount cache.
E : failed to mount cache/recovery/last_log.
ETC ETC...

There is an endless argument about this error. i cannot boot into stock roms because of this. i just want to clear dalvik cache now.

Is there any way to do it?
I'm not able to wipe anything in recovery mode.
i can access download mode only.

Try installing a custom kernel with Cwm and then try this.

Flash speedmod ics kernel and i can now access adb shell.. what should i do next?
when i enter this 'rm - r /data/dalvik-cache' command it says 'rm' is not recognized as an internal or external command. operable program or batch file.

I'm a noob at this. please direct me.

mistakenly entered a space in "-r" command.
if you get permission denied then run adb as root...

Code:

adb root
rm -r /data/dalvik-cache
rm -r /cache/dalvik-cache

is your data and cache partition mounted? Also first go to task manager and kill adb.exe.
then use the above commands.

looks problem with the memory block.. my support ends here.. may be you will need re-partition..
- you may try to rerun this after installing a newer recovery like cm10.2 kernel.
