How to Clear/Wipe Dalvik-Cache via ADB? - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

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.

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

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..

Yes installation by fastboot
Thanks a lot and wonderful job
so is this better than the clockwork recovery?
will this overwrite clockwork recovery if I already have that installed?
and the most important question:
DOES THIS WORK WITH PS3 JAILBREAK? I heard someone did it with this recovery, I want this to happen with the GT540!!!
I had clockwork now i have amon ra, it will overwrite clockwork when you install it
I've been trying to put this info my phone. But I have a problem.
Phone is ruining in fastboot mode, am typing command in cmd am pressing enter, then my PC reboot :/
Does somebody had the same problem?

Why you do that?
- Put your phone on fastboot mode
- Link it to the pc and turn on adb command
type:
fastboot flash recovery recovery_ra1.7swift.img
and you're done
I did this... I wrote I did. After ENTER the command my PC doing a reboot by itself, before apply recovery in my phone.

Is it working now? If it doesn't, download this: http://www.mediafire.com/?07qod3dg208mb30
Then, put the amon ra file in that folder.
- Put your phone on fastboot mode
- Link it to the pc and turn on adb command
type:
fastboot flash recovery recovery_ra1.7swift.img
you can try this method too (i use it)
1) copy recovery_ra1.7swift.img to sdcard
2) download/install some terminal into your phone.
3) run terminal and write :
Code:
#su
#flash_image recovery /sdcard/recovery_ra1.7swift.img
(or when it's not working:)
flash_image recovery recovery_ra1.7swift.img ;
flash_image recovery "/sdcard/recovery_ra1.7swift.img"
also you can to it in adb shell(connected into PC):
Code:
#su
#adb shell flash_image recovery /sdcard/recovery_ra1.7swift.img
or
Code:
#su
#adb shell
#flash_image recovery /sdcard/recovery_ra1.7swift.img
Hope this helps. (for me, it helped, because my computer freezes when using "fastboot flash" commands. )
Am reinstalling SDK and will check.
@hani93 thanks for this tut, it can be very helpful for me, cos my PC freezes too :/

no problem.
it should work.
(i googeld it for 4-5 days :S)
now i'm always using this method
I don't have to use fastboot with you method I guess, am I right??

that's right
just copy recovery image to sdcard (root dictionary) , install some terminal app( in market "terminal emulator" ) and enter commands...
and after that.. when you enter it . and terminal says "flashing recovery" ..or something, and then ends(with new command line)..
something that:
Code:
#su
#flash_image recovery /sdcard/recovery_ra1.7swift.img
flashing recovery...
#
make reboot and hold on home+power, and recovery comes up.
No way, so don't I need rom with fastboot to get recovery?? I just flashed my phone about 2 days ago with ROM+Fastboot to get recovery via fastboot (I lost some data - all angry birds saves).
And you are saying that I could use your method on my previous ROM without Fastboot, am I right??

Currently I'm trying this via fstab:
/data ext4 /dev/block/mmcblk0p8 length=-16384
/sdcard vfat /data/media
But that doesn't work. Perhaps it's something regarding the length.
As far as I could see the Samsung original recovery from the I/O device doesn't even mount /sdcard/ via fstab.
Perhaps we need to include a skript that does this work on recovery start.
EDIT: Tried fdisk -l to get the right partition to extract the original recovery.img but doesn't seem to be possible for me.
EDIT2: Found a skript that must be called on recovery boot. Need a way to include it..
EDIT3: Made another change to the recovery source - see https://github.com/SeraphimSerapis/Samsung-P7100-Recovery
I continued digging in the 10.1 system dump and found this in the vold file:
#dev_mount sdcard /mnt/sdcard auto /dev/fuse
dev_media_group * /mnt/sdcard/usbStorage/ auto /devices/platform/tegra-ehci.0
Perhaps there is a way to do some kind of this in the recovery.fstab as there is no vold file?
Mounting the sdcard fails currently saying this:
mount: mounting /dev/fuse on /sdcard failed: Block device required
Error mounting /sdcard
i have it mounting in CWM 3.1.01, without issue.
~ # mount /data; mount | grep "/data"; cd /data && cd /data/media && ls

I noticed when i try and do a nandroid it gets stuck in a loop. Thats cuz once it gets to backing up the data partition its also includes the recently created system .img, boot.img, recovery.img. and then gets stuck at data.img. This is cuz its backing up itself while it is creating itself.

[Q] [RESOLVED] Need instructions for installing CWM on ZV8 Rooted

I just need instructions on installing Clockwork on rooted zv8. The AIO does not work for me. It hangs at starting daemon.
Are you in internet connection mode with debugging enable? I know it sounds like a stupid question but I had a brain fart when doing it and forgot that part... doh!
My USB connection is broken, so here is how I did it using terminal emulator.
1) Download the cwmrecovery.img to your SD. ( I downloaded MT's zip file and then extracted all with root explorer, but you only need the cwmrecovery.img file.)
2) Use root explorer to copy or move it to the /data/local/tmp directory (make sure permissions are set to r/w/exe).
3) Launch terminal emulator and type these commands:
su
mount -orw,remount /dev/block/system /system
mount -orw,remount /dev/block/data /data
dd if=/data/local/tmp/cwmrecovery.img of=/dev/block/mmcblk0p14 bs=4096
rm /data/local/tmp/* 2>/dev/null
4) exit terminal emulator and then reboot.
You can then try the vol down+power button combo upon boot to enter CWM.
Good luck.

Where do I grab the local.prop and how do I put it in? :x
Same issue here as the rest. Getting "Operation not permitted" and permission errors
As I kept my local.prop as local.prop.bak, I renamed it back and restarted the phone, everything appears to have gone through now.
Thanks MT.

How do you change the permissions of the /data folder to r/w/exe as you mentioned?
I am having a problem because I don't currently have the Local.prop file and I need to add it to that folder but I am getting a permission denied message.

Partitions not mounting @boot

Hey Guys,
first off i had this issue once before, but in that case i could restore a cwm backup from sd card and after sometime the problem fixed itself,
this time, i switched to bacon and i wanted to prepare the p880 for my sister to use, i downloaded zaiben, formatted my external sd card and put the rom on it, i rebooted to recovery wiped( i used the clean to install new rom in philz recovery if i remember correctly) everything and flashed the rom and exactly as last time, the flash seems to go way too fast and ofc i cant boot into android. now as i formatted my sd i have no backup to restore to. kdz flashing seems hopeless as well, as none of the tools recognize the phone when i put it in s/w upgrade mode,
for proof: i checked /system with aromafm and found it being empty after flashing a rom, i even tried extracting the rom zip on sd and moving the content from the zip to /system manually but after a recovery reboot, /system was empty again( only empty "bin" folder)
is somebody able to explain me why i have this issue and maybe how to fix it, or upload a clean cwm backup of whatever rom for me to use?
thx
Thanks for the help until now, really.......
In Further investigation i could find out that Roms ARE actually flashing properly, but /system and probably other partitions are not being mounted
At Boot or in recovery(manually mounting works Here) which is why aromafm reports an empty /system, after a manual Mount in either recovery itself of Aroma console i can See /system being filled with Rom files, now i will change the thread title accordingly, and now ASK: can i force /system to be mounted at Boot somehow? Someone pls answer this time
Okay this is ridicoulous.... why am i getting no help AT ALL?, thank you srsly.....
i investigated even further and suspected that something with fstab might be wrong, but fstab file looks fine to me:
Code:
/dev/block/platform/sdhci-tegra.3/by-name/CAC /cache ext4 rw
/dev/block/platform/sdhci-tegra.3/by-name/UDA /data ext4 rw
/dev/block/platform/sdhci-tegra.3/by-name/APP /system ext4 rw
if someone bothers to answer: what do you think?
pls help........
bump
please help
What recovery are you using? Are you sure your partitions aren't formatted to F2FS? (which would explain why the (F2FS-) recovery can mount the partitions but the system cannot as it expects an ext4 formatted partition rather than a F2FS formatted one)
i'm using an older version of philz touch (i dont think it has f2fs functionality), as i had weird flickering issues with latest philz,
using cat /proc/mounts shows ext4 for /system and other partitions

could you give me a quick how to on using adb in recovery from pc? i put the phone in sideload mode and tried "adb shell dmesg" but the output just was "error close" and using the command in aromafm terminal gave me an endless stream of log
(Also currently need to charge the phone a bit)
EDIT: NVM kmesg incoming....
okay next question, how can i dump the output into a file and how do i know where it hangs? time in recovery is not correct anymore(i set it once but after reboot it was wrong again, also in kmesg the time again seems to be different)
does that part help? i think it has to do with boot

nah, I need the entire log
here's how you get it:
boot the system until it is stuck
hard reboot into recovery (don't enter sideload)
then run the following commands:
Code:
adb shell cat /proc/last_kmsg > /sdcard/last_kmsg
adb pull /sdcard/last_kmsg C:\whatever\path\you\like\last_kmsg
then post the file via pastie.com or any other online paste site

Yes, I meant that. But no kernel log seems like your boot partition/kernel is messed up... I guess you'll have to find a way to restore your entire phone via LG tools, I can't see any other way around that..

two last things then: when i hold vol - and then hold power until i reboot, recovery does not start, it tries to boot android again (has always been like that)
and also: all roms except cm official show no bootanimation before hang, cm does

1) yeah, I know, easiest way to fix that is to simply pull the battery and then boot into recovery
2) if the bootanimation shows up, it means the kernel as well as the ramdisk have booted properly. So in this case, you should be able to grab a last_kmsg as well as a logcat
hi
today I installed that application " LG-Optimus-4XHD-Recovery-v1.0.apk "
I have selected ClockworkMod Custom Recovery.
It showed that Operation is successful.
than i clicked on "Boot Recovery" to restart my Phone in CloclworkMod Custom Recovery.
since then I am getting only Starting animation. (LG LOGO).
nothing happens.
My battery was full when i performed this procedure
any help please

Getting ext4 file-system instead of squashfs on LG G Watch R running Android 6.0.1

Code:
#include

* I am not responsible for bricked devices, thermonuclear war,
* or you getting fired because the alarm app failed.
* YOU are choosing to make these modifications, and if you point

*/
To do this you'll need a Linux machine with fastboot and adb set up, I'll be using Ubuntu 15.04.
Setup stuff
1. Download and extract GWatchR_lenok_601_MEC23G.zip
2. Download and extract this tool, unless you have something else for boot.img editing.
3. Download and extract this tool
Modify boot.img
1. Open terminal and cd to folder with unpackimg.sh
2. Copy boot.img to the same folder
3. Run ./unpackimg.sh boot.img
4. Open ramdisk/fstab.lenok and edit line with /system info so it'll look like this:
Code:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,barrier=1,discard wait
5. Run ./repackimg.sh and copy new boot image somewhere safe.
Setup partitions on watch
NOTICE: Following steps are very dangerous and might brick your watch forever!
1. Make sure you have MEC23G installed on your watch.
2. Flash GWatchR_lenok_601_MEC23G/twrp-3.0.0.img using fastboot:
Code:
fastboot flash recovery path/to/twrp-3.0.0.img
3. Flash your new boot image:
Code:
fastboot flash boot path/to/newboot.img
4. Reboot your watch into recovery mode
5. Open terminal and type:
Code:
adb shell
cd /sys/devices/virtual/android_usb/android0
(sleep 5 && echo 0 > enable && echo "adb,mass_storage" > functions && echo "/dev/block/mmcblk0" > f_mass_storage/lun/file && echo 1 > enable)&
6. Now open gparted on your PC
7. Go to ~4GB disk's partitions
8. Delete 19th and 20th partitions
9. Create two new ext4 partitions, 19th should be ~384MB now and 20th ~127MB
10. Right click on each of partitions and then choose 'Manage flags' and check 'msftdata'
11. Apply all changes
12. Open Disks
13. Select 19th partition click button with two gears then click 'Edit Partition' and in name filed type system and click 'Change'
14. Select 20th partition click button with two gears then click 'Edit Partition' and in name filed type cache and click 'Change'
15. Now close gparted and disks and eject watch partitions
16. Reconnect watch
17. Open terminal and type:
Code:
mkdir system
mount -o rw -t ext4 /dev/sdb19 ./system
NOTE: /dev/sdb19 might be something else on your device, you can find this path in gparted or disks
18. Now type:
Code:
sudo path/to/unsquashfs -f -d /full/path/to/system /full/path/to/system.squashfs.img
19. Type sync and wait for it to finish
20. Eject watch's partitions and wait till you can unplug it
21. Reboot your watch (adb reboot)
Should boot now
Nice post but not really a good idea playing with partitions

Yeap, but I need 6.0.1 with writable system. Just sharing my experience
Will this also work with newer Firmwares like MWD84B or M1D63G?

Probably, haven't tried that. You'll need to use differn zip with rom stuff.

Worked perfectly.I updated my Watch to the latest OTA and then dumped my system and boot with these two commands
dd if=/dev/block/mmcblk0p15 of=/sdcard/boot.img
dd if=/dev/block/mmcblk0p19 of=/sdcard/system.img
and then copied them to my laptop via adb pull and changed the stuff
Curious how OTAs will work now. Probably not or I have to change some stuff.

OTA will probably not work. It needs squashfs but we have ext4. You might try editing update zips.
Can you provide a zip file for having a rom with this filesystem?
Thank you!
If is possible...
I can't delete dev/sdc19 /system filesystem is unknow..
Any help?
Thank you!!
Edit:
I've done M1D63X with linux mint and i've installed also sqashfs-tools
sudo apt-get update && sudo apt-get install squashfs-tools
I messed something up... Yeah...
When I try to flash system in ADB I get "FAILED (remote: partition table doesn't exist)"
Help?
sounds promising. i have an urbane 2. is there anyway, i get this running on it in the same way? its aw2 by now. will have a look at the partitions when i come home and send it here.
do i have to delete cache and system?
why did you delete 19th and 20th????
