I was trying to free up space and saw LG Home was taking up some space. Never knew it was a critical launcher. Ive tried millions of methods on various sites including xda, android forums, android central with no luck. Here is a rundown of the situation.
1. I had clockwork installed then it "disappeared" adb reboot recovery stopped letting me go to the clockwork bootloader
2. I have a custom ROM sitting on an sdcard called Cyanogen.zip Its never been messed with yet.
3. I do not have a "nandroid" backup or backup of the stock rom because clockworkmod never worked
4. Doing a factory reset did not fix the issue because apparently the OS runs live off the rom aka it never installs itself to the device like in WIndows . SO I get a total black screen setup screen with only a signal bar on top.
So the latest thing ive been trying is adb pushing a copy of LG_Home into the /system . This is not working because im getting a "permission denied" . Now before you get hasty please do not have me do these commands:
1. mount /system already did this back when doing clockwork
2. remount -o ,rw does not work, probably due to already having root
3. adb root tried it and it doesn't really do anything, I still get permission denied, and usage errors
This does not make sense because the phone is rooted (does factory reset take away root? ) , chmod 777 has been applied to /system . If I lost root doing a factory reset, is there a way to root the phone now that I don't have a functioning phone?
Here is what im aming to do with your help
1. Force the LG_Home.apk file into the /system
2. Force some way to get cyanogen mod installed as I now have a corrupt stock rom
Something has to work and im hoping someone will help me

Hoping for some assistance in troubleshooting here, successfully rooted my phone and attempted to flash voodoo using the methods described in the following thread:
HOW TO: Root, Install Clockwork, Safely Remove Bloatware, Integrate Google
To my knowledge everything worked as described until I attempted to install voodoo. Upon doing so the phone booted very quickly back into what appeared to be the stock kernel/system. I lost my superuser.apk application but still retained the su and busybox files on my sd card. I have cwmod installed and can access it but the voodoo install appeared to have failed.
My problem is that I believe the device is still rooted, because when I launch adb shell it presents a # prompt, but when I attempt to perform a factory reset (I would like to start the whole process over) the procedure errors out with the message that partitioning failed and E:Can't mount /dev/block/mmcblk0p1 (Invalid argument).
I've tried the fix permissions and format SD card options within CW recovery without any luck (the only result is that now I don't seem able to install any apps; the phone believes there is no space). I also attempted to use Odin to restore factory kernel/system status but the problem persists. My goal right now is to get everything back to factory and start all over, any advice would be much appreciated.
Voodoo definitely failed and your MBR is messed up now. (Invalid argument)
Please use the voodoo uninstall in the OP of this thread to remove the damage.
You can then make another attempt at installing the voodoo kernel if you wish.
Will do so shortly, appreciate the quick response
This corrected my problem. Thank you for the referral PhoenixPath, and thank you adrynalyne for taking the time to put this together for us mouth breathers
I wanted a clean cyanogemod installation on my desire z so I followed this guy's advice:
For a clean install, just boot into recovery, format the /system partition (found under the Mounts and Storage menu) and then perform a Factory Reset/Data Wipe. After that, you are good to install CM and gapps. This does not erase your sdcard, so if any apps stored stuff on there, it will still be there unless you manually erase it.

I didn't think it through and restarted the phone thinking I'd use clockworkmod to reflash the cyanogenmod rom. When I turn it on now it just displays the green 'htc' text on white background, none of the buttons do anything.
I've still got adb etc installed from rooting a year ago, is there a way I can unscrew this up? A million thanks.
Edit: When I start it and go to the loader screen by holding down the optical button, it gives me 'bootloader' as an option but when I select it, it looks like it scans the SD, tells me there is no image and offers to start an update. I can see it with adb but can't get a shell, it says - exec '/system/bin/sh' failed: No such file or directory (2) -'. Is there a boot file I can push onto it?
Read one of THESE.
I believe adb push a ROM and gapps to /SD card.

It seemingly randomly booted in cwm recovery after about 30 on-offs and I loaded the cyanogen rom, not a satisfying fix but I'll take it. Thanks for your help.
Hi,
I own a rooted Lenovo P780 that was bought as a gift. The phone was pre-rooted (the bootscreen mentions lenovo-forums.ru, I think it's a worldwide ROM that's installed). It's been fine for a year, but in the last few days, the internal storage has maxed out, causing problems with updates.
Yesterday, I tried something as an experiment without really thinking through the full consequences.
I had busybox and terminal emulator installed so I made a copy of the /data/dalvik-cache in the built-in SD card (since it's always present and I have an external one for all my regular data), renamed the existing dalvik-cache directory to dalvik-cache-bak (as a precaution before outright deleting, lol) and created a symlink to the new location. Everything was fine, until I restarted...
I'm not sure if the permissions are invalid or the internal SD card is not mounted early enough in the boot sequence but now the phone is basically crippled. It's not outright bricked; it does progress so far into booting, then opens many requesters about all the stock applications failing. It basically gets stuck trying to restart them.
I've not really used ADB before, but I assume that it should be possible to mount the /data partition, remove the symlink and rename the dalvk-cache-bak to dalvik-cache and at least get the thing working before resorting to some sort of factory reset.
I feel completely nubular for having to ask, but the question is, what exactly do I need to do to get into the device?

Hi. Try this: reflash stock 124 ROW firmware, then upgrade to KK.
Look in my posts for Stock 124 Firmware and how to root.

Thanks for the post. However, I really don't wan't to reflash the phone just yet as there is data (contacts etc) on there that aren't synced yet and I don't want to lose. Also, reflashing the phone to fix a basic filesystem issue seems like using a nuke to crack an egg.
I need to be able to boot the phone into recovery mode, but I can't seem to find any option for that. The only key combination that does anything different than a regular boot is holding power & volume down which boots into "meta mode", which doesn't seem to be useful.
Is there some special trick for this model to get into recovery mode?

Did you tried key combination like: power + vol up and down pressed together?

I used an app from the play store called root uninstaller, only after I used it and my phone buggered out did I read other users comments.
I noticed that if you install the app, when trying to use it if you click on an app to uninstall, you actually get the app listed before the one you clicked.
Now I've uninstalled an app I have no idea which, now I get a login screen, when I swipe the lock to unlock I get a message, something like "System UI has stopped responding" then locks itself again. (maybe I uninstalled System UI?)
I can turn the phone off, then start up into recovery mode, I get the following options.
reboot system now
apply update from ABD
aplly update from sdcard
apply update from cache
wipe data/factory reset (this doesn't reset the phone to original state, just wipes data/cache)
wipe cache partition
backup user data
restore user data
Now the thing is this is an unknown Chinese brand, I have a 2nd one that is still working.
How can I get this to work again?
Are both the phones rooted?
Are these stock recoveries or custom?
If custom recovery, you can take a clockwork mod backup of ok phone and install on non working phone.
If no custom recovery but rooted, then you can pull the system folders of both phones on pc and compare the folders for missing apps.
Then push missing app via adb.

Thanks for your reply.
Before the phone went downhill, yes it was rooted, the other phone isn't rooted but that is easily done.
I couldn't install the clockwork mod backup though on the phone that went down.
How do I pull the system folder off the broke phone? I can't get it past the boot up screen anymore.
The android on it is coreandroid. I hate it.
Install adb on your pc.
Get to know basic adb commands.
On the computer command prompt with the good phone connected, do
adb shell
su
cd /system
ls -al
This will list all apps in system folder.
They will be numerous.
Do the same for bad phone.
Comparing the files, you can identify the missing file.
---------- Post added at 09:17 PM ---------- Previous post was at 09:14 PM ----------
ON the second Note , you can do
adb pull /system/ >c:\system1
This will pull all system files to the said folder in c drive.
Do the same for other phone
adb pull /system/ >c:\system2
Compare both the folders to find the missing file.
