Hello,
I restore my original rom and I have only to remove the custom recovery menu to return my phone in original state. I want to return in original state because I need for waranty service. So can someone help to remove custom recovery menu? I think that my USB port on phone is brick and I have problem with display.
Did you backup your original recovey before installing the custom recovery?
No. If someone has it could you share with me the file and short explanation what to do.
I will send you my original recovery. And I will tell you how to flash it. Lemme reach my home.

EDIT: you "might brick your device". not my responsibility.
My original Recovery - http://rapidshare.com/files/450046207/original-recovery.img
Now to flash it -
1) - Copy it to the "Root" of your sdcard
2) - Open adb or terminal emulator and type the following
Code:
flash_image recovery /sdcard/original-recovery.img
[source http://forum.xda-developers.com/showthread.php?t=900905 ]
Again "Do it at your own risk"
I will try and i post what is the result.
This is a better way to revert everything to stock. As long as you read all the comments properly, it also removes any custom roms you may have.
So in terminal emulator I will write:
<su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
flash_image recovery /sdcard/original-recovery.img
reboot recovery>
or it is enough only
<su
flash_image recovery /sdcard/original-recovery.img
reboot recovery>
I do it with terminal emulator with this comand:
"su
flash_image recovery /sdcard/original-recovery.img
reboot recovery"
and all is like stock state. Now I will go to bring the phone to the shop.
Glad I could help. Good luck

I wanna install a custom ROm on my lg optimus one but something goes wrong. I installed z4root and rooted the phone. Then i installed terminal emulator and typed the specific code starting with su .The phone restarted and i pressed and kept pressing the 3 buttons (power+vol. down+home) but no menu apeared. I did the procedure 10 times but the menu didn't apeared. Am i doing something wrong or my pfone is brocken?
Did u copy paste all commands at once?
I did it manually tiping it by hang on my phone. I didn't coppy the text from my computer.
seems you didnt unzip the two recovery image files. Check it.
I unzipped all the files the image file, the recovery file, everithing. And i coppyedboth the zipped and the unzipped files
I checked it again and i have ony one recovery file and not 2... Which is the second recovery file?
Read this, I just instructed another user on how to upgrade to version 1.2 of the custom recovery. You should install it too. You will find links to the two files and the commands to type in the terminal.
Good luck!
flash_image.zip ??
I have flash_image zipped and unzipped
Use this: http://forum.xda-developers.com/showthread.php?t=971245
when i type the code it says:
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
# cat /sdcard/flash_image > /system/bin/flash_image
cannot create system/binflash_image: read-only file system
# 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/mtdblock1 /system
# flash_image recovery /sdcard/LGp500-recovery-v12.img
# reboot recovery
Use what I told you and forget about those lines !
Try copy paste each command one by one....
I did just like here: http://forum.xda-developers.com/showthread.php?t=971245 but an error apeared: "windows cannot find groot.exe". I saw that there was anotxer member with the same problem but i didn't understood how to fix it.
try copy paste from stock browser on phone to terminal
How can I do this without a sd card... thanks in advance.

Flash the recovery image?
Root
Adb push a flash_image binary to /system/bin or xbin
adb push recovery.image to /cache or something
flash_image recovery /cache/recovery.img
I'm trying to flash the recovery without a SD card, because my phone can't mount a SD card anymore. So I'm using the recovery here http://www.lg-phones.org/lg-optimus-v-custom-recovery.html and Flash_image to flash it, but I need ADB codes to do so. I'm not very good with ADB, so I need the ones without the flash_image recovery /sdcard/ recovery-thunderc-v-1.2.0-GNM.img /sdcard/ part. :/

It the same thing as tvall has mentioned but I will make it more easy for you.
As mentioned in the link that you have provided, just do this instead:
A) Type in 'adb remount'
B) Copy recovery-thunderc-v-1.2.0-GNM.img to platform-tools directory where android SDK is installed.
C) Do a 'adb push recovery-thunderc-v-1.2.0-GNM.img /system/xbin'
[Now the recovery image is inside your phones memory @/system/xbin location]
Following are the existing steps from the link: Modified step is made bold.
1) mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
2) cat /sdcard/flash_image > /system/bin/flash_image
3) chmod 755 /system/bin/flash_image
4) mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
5) mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
6) flash_image recovery /system/xbin/recovery-thunderc-v-1.2.0-GNM.img
7) reboot recover

Here the 'recovery-thunderc-v-1.2.0-GNM.img' file should be present inside the C:\android-sdk\platform-tools directory. Also check if the spelling is correct.

This error came because there is no file called 'install-recovery.sh' inside /system/etc. This is fine since you are anyways not going to use that file.

This part I am not that clear but it might be that the recovery 'recovery-thunderc-v-1.2.0-GNM.img' is corrupt or may be 'flash_image' is corrupt. You can also check for the amount of free memory by typing in 'df' and 'free' respectively. df would give you phone memory stats and free would give you RAM stats. Verify if anything is too low.
For the last permission denied error do a 'ls -l' at /system/xbin and check for the permissions.
I will look around to see if I can get some clues till then, lets wait for someone who can help you better.
[ADVICE: Since you are playing around with system binaries make sure you take a backup of /system/bin atleast.]

I tried again about 8 hours ago. I got through everything with no error, but when I got to recovery, it was still the old one. I'll try again once I get home.

Other option (if your phone is rooted)
Install RomManager and install CWM or alternative.
If you're not rooted you need to do that first.
After that you can flash any recovery you want and you don't need to mess with adb
You can try to flash a recovery via LGMDP. I've flashed CWM 4.0 by this way.

Can someone with a sd card, and adb, test this out? I don't want to test it out, cause without a sd card mounter, if it doesn't work, I'm screwed. If it doesn't work, I'm sure you have a nandroid on your sd card, hopefully. Please and thank you.

prejudice I have noticed that since version 1.5 I do not have all the permissions of root, after having installed the system with :
./adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
exit
exit
./adb push framework-res.apk /system/framework/framework-res.apk
I have been informed that I do not have permission, I also tried to install the original firmware, making the root of this (and everything is fine) and install Paranoid Android 1.6a (I have no permission). please can you help me? Thanks to all

have u check your device with ROOT CHECKER https://play.google.com/store/apps/...GwsMSwxLDEsImNvbS5qb2V5a3JpbS5yb290Y2hlY2siXQ.. before u install Paranoid Android Rom??
Hit thanks if i helped you friend
Try "adb remount" before trying to push file into /system
If the command come back with error, you will need adbd insecure. Normally custom kernel would have include it, but for stock kernel it was not included.
There is an app made by chainfire to enable this feature, you can find it here. Enable USB debugging on your phone, patch it.
Hi! I'm having a few problems with my Galaxy Nexus, as it's been not booting with this CyanogenMod 11S bootanimation.zip I've been trying. I now want to remove it, but I can't boot into recovery due to hardware issues. I can adb into the phone though, but only shortly, before the system locks up.
I'm trying to do the following:
Code:
su
mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
cp /sdcard/bootanimation.zip /system/media/bootanimation.zip
However, I can't use "su" - nothing really happens. It won't give me root, but it doesn't give any errors either, the $ sign doesn't change into a # sign, thus remounting system to rw fails and subsequently, I can't copy anything there.
I'm running PACman (4.4.2) and I have SuperSU installed. Any ideas?
Edit - Kind of solved, forgot adb reboot recovery existed.
Hello everyone
Can somebody help me i have accidently changed the permission of the folder /System/bin to [rw-r-r] in my lg g3 using CM13 nightly latest version.

How do you accidently changed them?
Reffering to this Thread you could use adb to change permissions in recovery by:
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
chmod 755 /system/bin
Edit: When just coying and pasting I forgot, that the part
Code:
yaffs2 /dev/block/mtdblock3
may be a little bit different on your device. I do not have a G3 at hand and did not find the fstab that fast, but you can run
Code:
mount
Code:
cat /proc/partitions
and so on out of the CM Porting tutorial to find out your parameter.
