If all goes well, the menu with a cheerful hat ClockworkMod background confirms that the boot recovery occurred in CW.
Also ignore the error below: "E: bad boot message" is not a real error.
The recovery functionality is simple:

- The back button to go back
- The power button to select a menu item.
If you have problems, you can select Advanced / Error Reporting. This will generate a log into SD (recovery.log). You can use it to understand the problem.

Doesnt work for me, recovery just freezes at the LG screen

Need to understand what is recovery and custom installation
May I know what is Custom Recovery for LG Optimus Net - Clockwork 5.0.2.7 and what it do?
and what is installing cyanogenmod 7.0 is it a custom rom and is it better then stock rom?

Hi guys,
I have problem. I rooted my LG P690 and installed CWM bootloader. During installing custom ROM my phone bricked and rebooted after LG initial picture. I was able to enter only RECOVERY MODE by pressing PWR+BACKARROW+VOL_UP. But that was all, I couldn't also repair phone through HDZ_FW_UPD.exe , because problem with USB drivers. I tried everything, but without success. But I was able to connect to phone via ADB commands, downloaded update.zip, added it near fastboot.exe file, run fastboot and install that update.zip. I removed SD card to other phone, connected, uploaded some CyanogenMod 9 and moved SD card back to LG P690. Now I was able to enter BOOTLOADER (BUT I DON'T REMEMBER COMBINATION OF BUTTONS DURING SWITCHING PHONE !!!), and installed CyanogenMod9. Everything looks OK, but after rebbot and entering new Android OS my touch screen isn't working. I don't know why, but I think that problem is in that CyanogenMod9 version - it doesn't recognize touching screen. It reacts to pressing Vol UP/DOWN buttons (setting volume), pressing BACK button or long pressing PWR button. But that's all. I can turn off the phone by remobing battery. When it's ON and I connect it via USB, I cannot use ADB.exe or FASTBOOT.exe commands because PC donesn't recognise device
So now the question - how to enter bootloader during power ON sequence? I tried all combinations:
- pressing and holding PWR+VOL UP
- PWR+VOL DOWN
- quick pressing of VOL UP
- quick pressing VOL DOWN
- pressing PWR+BACK+VOL UP
- pressing.....and so on and so on
I don't know why I cannot access bootloader becasue before I did it without any problem....Can you please write me detailed "butto n sequence" for entering bootloader on LG P690 Optimus Net? Or am I LOL?
Thank you very much
Rado

SOLVED -> entering bootloader works with pressing HOME+VOL_DOWN+PWR_ON

[Q] HELP: ASUS TF700T stuck at booting CyanagenMode 10.0 (STABLE)

I have used CyanagenMod 10.0 STABLE ROM without any issue for several days until this Morning where my Google Play kept giving error "insufficient storage space" for some reason. I read from several discussions abt this as none of them fix my problem so I decided to do followings:
Using ClockModRecovery 6.0.2.3:
1. wipe data/ factory reset
2. wipe cache
3. wipe dalvik cache
test: still got same problem
4. wipe data from the last option where there are four icons shown (Recovery, Android, USB/fast boot/ Wipe Data icons)
5. access recovery mode again and do followings
6. format system success
7. format /staging - success
8. format /data - ERROR mounting /data!
9 reboot device and still stuck at booting (THE CyangenMod logo kept showing)
10. access recovery mode again -> mount /data and /emmc FAIL
When I click the USB icon duriing initial boot, my PC (Win 7) could not detect my tablet device but when I chose Recovery mode, my PC was able to detect the device with some errors. The folder structure is shown below.
H:\Downloads\Android\TF700 Rooting>adb shell
~ # ls
ls
btmac init sys
cache init.rc system
data proc tmp
default.prop res ueventd.cardhu.rc
dev root ueventd.goldfish.rc
emmc sbin ueventd.rc
etc sdcard
fstab.cardhu staging
When I access the system folder, there is nothing there/ I tried using below config to flash the CM10.0 ROM again and wish to fix my problem:
H:\TF700 Rooting>adb push update.zip /root/update.zip
1333 KB/s (169361362 bytes in 124.049s)
It seemed the file had been transferred but the issue remains.
I have two questions:
1. Is there anyone who knows how to enable USB debugging from clockmode recovery? I might not enabled this earlier. I s there a way to check from ADB command?
2. Any suggestion to help me recover my OS? The bad thing is that I backup my ROM to internal EMMC and now it is not mountable for some reason
Further the ADB outputs are below:
H:\Downloads\Android\TF700 Rooting>adb devices
List of devices attached
015d2XDXXXXXXXXXX device -> serialno is hidden purposely
H:\Downloads\Android\TF700 Rooting>adb get-state

If you don`t have an efs backup, then unfortunately there is nothing you can do except sending it to a service center, happened to me almost 6 months ago, tried all options , nothing was successful, had to send it for repair.:crying:

Here is the exact solution for this problem which i have recently had!
You have to root your phone and install Terminal Emulator from Google Play.
Open terminal emulator and type as ;
su
rm /efs/FactoryApp/keystr
rm /efs/FactoryApp/factorymode
echo -n ON >> /efs/FactoryApp/keystr
echo -n ON >> /efs/FactoryApp/factorymode
chown 1000.1000 /efs/FactoryApp/keystr
chown 1000.1000 /efs/FactoryApp/factorymode
chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
reboot
You now should not see the that message anymore. Its because of an EFS corruption.
Hope it helps!!!

[Q] GS III Debrick Escapade

So, I mistakenly used Ez-Unlocker with 4.4.2 and bricked my GS III. Based on various posts found around here I was able to get it running again. However, no matter how many times I try to reset the phone, either through Odin or the Verizon repair utility, this is what I get:
[[http]] [[://]] www [[dot]] ledzilla [[dot]] us/images/Screenshot_2014-07-19-14-13-55.png
I've tried various methods I've found to resolve this, but the best I've managed was to delete a trio of apps from the phone with the name "Factory Mode" and "Factory Test", but all that accomplished was getting rid of the yellow text that persists across the home screen. I still got the the warning box at the bottom of the screen.
So, is there a way to completely fix this with the phone being on the latest firmware and OS?
Also, on a side note, I received a warranty replacement because I didn't realize it was EZ-Unlocker that caused the problem until I did it on the replacement, too. I was able to restore it back to working condition, too, and without the factory mode issue, except the same exact process caused the EFS data to get corrupted so now there's no IMEI. Here's a screen shot of the system data (there's no SIM card installed, so I don't know if that affects some of these values):
[[http]] [[://]] www [[dot]] ledzilla [[dot]] us/images/Screenshot_2014-07-19-19-37-44.png
Is there any way to fix this issue, too?
And sorry about the links, but I'm assuming most here would know why it's all chunked up like that.

I should also mention that in order to resolve the issue I have rooted using Towleroot, and I installed Superuser for, well, super user rights. In conjunction with this, I also accessed the phone using the ADB shell and entered the following:
Code:
su
rm /efs/FactoryApp/keystr
rm /efs/FactoryApp/factorymode
echo -n ON >> /efs/FactoryApp/keystr
echo -n ON >> /efs/FactoryApp/factorymode
chown 1000.1000 /efs/FactoryApp/keystr
chown 1000.1000 /efs/FactoryApp/factorymode
chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
reboot
I was able to confirm changes to the files, but it effected no change on the situation. The yellow text did not go away and the "Factory Mode" message still appeared at reboot and shut off the WiFi.

[Q] ADB SHELL CHMOD 644 ,nothing is working anymore...

Hello everybody
I needed to push a file to /system/app but since I was on stock rom & kernel, that didnt support adb root.
I needed to be able to push the backup file after restart but ADBD Insecure couldn't patch after restart.
my phone is optimus G E975 , fully stock 4.1.2
I found this command which could do the thing BUT :
adb shell
su
chmod 777 /system
since it didnt restore to default after restarted I tried to restore it myself(didn't work) with:
adb shell
su
chmod 644 /system
but after that every thing force stopped & after restart, phone can't boot anymore,just when want t start boot animation, it just cant & goes to recovery every time!
even Hard reset didnt work, but as stock recovery supports adb, I wish you guys can help me. but It seems adb shell gives permission denied(13) in recovery. please someone help...
Anyway am I able to flash in download mode????? (for the last solution)
any help to change that CHMOD to 777 in recovery or something else?
any help appreciated so much!

After using this command, it seems the /system directory became unreadable,
FIX: after flashing e975tot rom through LGNPST in DW mode, the phone booted up normally & problem fixed.
