-Don't mount sdcard
-usb debugging should be on(checked)
-Make sure your getting the path to the folder where adb is located.


If you using termminal on the phone you don't use the adb command you do

-su
-the the rest of the commands.

After I type in su it asks for a password. What password is it asking for? it isn't my computer password

Is there a fix for the being frozen at the LG splash screen?

Do you have a working custom recovery? If so boot into recovery and flash a rom or do a nandroid restore.

Ok… I’m a noob as the title above my name will tell you so this may be an easy answer but whatever it is I will need the answer in terms a 5 year old can follow. : D I have rooted my phone and got one of lego rom with the BuildProp-Deluxe-No-HTTP etc. etc. It works GREAT! I have rooted my wife’s phone and when I open the Terminal Emulator and put type in su to get the “#” then I type:
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
# flash_image recovery /sdcard/recovery-RA-GNM-thunderc-s-1.1.0.img
# reboot recovery
Without the “#” of course then I get the phone saying “cannot create /system bin/: is a directory” I have un zipped the flash_Img.zip and the recovery-RA-GNM-thunderc-s-1.1.0.img.zip onto the root of the SD card. How do I get past this part?

 

[jmzsctt]

i just got this from the Terminal Emulator "cannot create /system bin/flash-image: read-only file system"

 

[jmzsctt]

OK... I'm getting the “cannot create /system bin/: is a directory” response again over and over.

Okay, I have tried three times to custom recovery my phone but each time my phone just reboots with the LG logo, thankfully this brings it back to stock so I can try again XD

But I still don't understand why the same thing keeps happening, I have rechecked each line I type in, checked the md5 sum on all files, I even formatted my sd card so there are only 4 files on it.

z4root.1.3.0.apk
ThundeROM_V1.6.2.zip
recovery-thunderc-s-RA-v1.2-GNM.img
flash_image

So any help is appreciated ><;;

NOTE: after I do the second last step, where I flash_image recovery /blah/blah and the next line is always screwing up, as in, I don't get the # at the start automatically, is that just with me?

EDIT: an error I keep getting when reverting to stock is this:

01:39:31 : _SetAuthMark Fail
01:39:31 : AuthMark?? ??Ȯ?? Phone?? Write ???? ?ʾҽ??ϴ?!
01:39:31 : _SetAuthMark Fail
01:39:31 : LoadCDMAPhoneData() Error

Could that be the reason why custom recovery won't work? ><

Is there a fix for the being frozen at the LG splash screen?

refer to this, you need to get into emergency mode BEFORE you connect your phone, otherwise it just auto startup

i just got this from the Terminal Emulator "cannot create /system bin/flash-image: read-only file system"

Did the first command run fine without giving any errors? And are you trying it as root?

 

[AzNxJoHnNy]

OH YEAAAAAAAAA

i mananged to finally perform custom recovery on my phone, I had to use the 2 files from here BUT i followed the instructions on what to type in from the first post. So for those who keep getting the LG logo and restarting, try that, it worked for me =D

 

[mkho30]

this recovery is amazing, great stuff

 

[jmzsctt]

Did the first command run fine without giving any errors? And are you trying it as root?

After I type # “mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system” into the Terminal Emulator I get “Usage: mount [-r] [-w] [-o options] [-t type] device directory”. I rooted her phone with Z4root and its rooted as far as I can tell.

 

[ke4tzn]

I send the su command in adb and it tells me permission denied any other way to do this?

 

[Fletch888]

Thank you very much for your help. I read the first two pages and then tried it on my Virgin Mobile Optimus V (VM670) Running Android 2.2.1.

One step had a problem.
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
This told me that no such file or directory exists.

I went ahead with the rest of the procedure and it worked fine. I was able to make a back up and reboot to regular phone use. I rebooted again to the recovery menu with the vol-down + home + power key combination and it worked fine.

Thanks again.

ETA: I rooted the phone by following the instructions in this thread first, and I'm glad I did. I wouldn't have known how to get to the # and begin the process otherwise.
