General :: IMEI Recovery - LG Optimus L3

Sep 23, 2012

After update my Optimus L3 got in a "No service" situation. The strange part is that i have signal and im able to access the internet using mobile network (wifi off). After a long research i fugered out that my IMEI was 0 (zero). I finded a lot of solutions to this problem but none of then was compatible with my device or brand.

Its possible to perform this in an Optimus L3? How can i access the Port Settings?

(ultimate solution for several LG devices) Restoring IMEI

1.Connect phone by USB
2.Activate USB debug mode
3.Enter 3845#*920# in dialer if that doesn’t work try 3845#*925#
4.Select Port Settings -> Select CP Image Download
5.A new device should appear at let it install
6.Open Tutty and select serial protocol. Click on open
7.Type AT if response is not OK, change port number (it is possible that when typing you don’t see any letters)
8.Type at%imei, it should display a dummy IMEI
9.Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x where x,x,x... is your orginal IMEI number (found under the battery of your phone). It should response IMEI WRITE OK
10.Reboot phone

General :: CWM Recovery - LG Optimus L7 II P710

Oct 6, 2013

I'm trying to porting cyanogenmod, but I have a problem unlocking the bootloader for recovery. Let me explain what I've done so far.

Root Phone via framaroot
Extracts recovery.img boot.img via adb

sudo adb start-server
adb shell
dd if=/dev/block/mmcblk0p9 of=/sdcard/boot.img
dd if=/dev/block/mmcblk0p17 of=/sdcard/recovery.img
adb pull /sdcard/booty.img
adb pull /sdcard/recovery.img

Initialized the project via

mkdir ~/android/system/vendor/LGE/vee7e
mkdir ~/android/system/device/LGE/vee7e
~/android/system/build/tools/device/ LGE vee7e ~/boot.img
cd ~/android/system/
. build/
make -j4 revoveryimage
make -j4 recoveryzip

I now have the CWM Recovery, and I inserted in my phone

cd ~/android/system/out/target/product/vee7e/
adb push recovery.img /sdcard/recovery-cwm.img
adb shell
dd if=/sdcard/recovery-cwm.img of=/dev/block/mmcblk0p17

Reboot the phone for enter in recovery mode (hold volume up + home button), and I had this surprise

[4380] -------------------------------------------------------------------
[4380] Secure booting Error!
[4390] Cause: boot certification verify
[4390] -------------------------------------------------------------------

In the attached you will find my recovery and the error message.

General :: LG Optimus P350 - Can't Get Into Recovery

Nov 4, 2012

So I wanted to install a custom ROM to my P350 today and it seems I can't get into recovery mode. When I try to get into recovery, it shows the LG screen, shows that recovery mode screen, freezes on that screen, reboots and EVERYTHING ON MY PHONE GETS RESET,

I've tried 3 different ways to get into recovery, all of them have this result. It is very annoying that each time I try to get into recovery the phone gets a factory reset. How can I get into recovery?

General :: LG Optimus G Recovery Red Triangle?

Jul 7, 2013

I cannot get into my recovery. Alright so i bricked my AT&T lg optimus g after trying to delete some bloatware after rooting my phone. I unbricked it by using LGNPST and got stock android 4.1.2. My software version is E97020j. The phone works perfectly fine but i cant get into recovery and i want to flash some custom roms. I can root my phone perfectly fine. The only way ive seen that unlocks the bootloader of the optimus g is a program called project freegee. When i try it, it tries to reboot into my recovery and bricks my phone. Then i have to use LGNPST again.

Ive used apps like clockwork mod manager and it says i already have TWRP and Clockworkmod recovery installed but it wont reboot into any of them. It just comes up to a black screen and says "Secure boot error, cause: boot certification verify." Ive tried getting into recovery using adb on my computer and using the old hold power button and up volume button method but nothing has worked. I cant find online how to get my old stock recovery image or how to fix the red triangle and i dont know how to uninstall TWRP and Clockworkmod. The methods for other phones doesnt work on mine.

General :: LG Optimus L3-8C Not Reboot Into Recovery Mode

Jul 1, 2013

I recently rooted my LG Optimus L3-8C (E400) running stock rom and version 2.3.6 Gingerbread (yuck) and I followed all the instructions from this video:

in order to flash the CM9 ROM. Problem is I can NOT reboot into recovery no matter what I do it seems. When I try tp reflash the CWM recovery it tells me "successfully installed!" then when I press 'reboot into recovery" it gets stuck on the LG logo for so long I often have to hold the power button to go back to my device. I even download "recovery flasher utility" found here [URL]....but, whenever I run the app it tells me "no recovery.img" found onexternal SDCARD even though I placed it there! I tried to fastboot but whenever I run CMD it tells me " 'fastboot is not recognized."

General :: Unable To Boot LG Optimus G Into Recovery

Mar 28, 2014

I'm having trouble booting my LG Optimus G into recovery mode. I've rooted the phone and installed ClockworkMod recovery. When I try to boot into recovery, either from the ROMmanager app or by holding Volume Up and Power, it comes up with the LG logo and gives this error: Secure Booting Error! Cause: boot certification verify. It just stays like that until I press and hold the power button again until the phone shuts off entirely. Then I'm able to boot into the stock operating system and the phone works fine, but I can never get it to boot into recovery.

The error I mentioned above seems to be a well documented error on the internet, but it seems like other people that are having the trouble are completely bricking their phones. Mine is able to come out of it. All the solutions I'm finding pertain to a phone that's completely bricked and involve taking the phone back to stock. My phone works fine with the stock ROM, but I'd like to play with some custom ROM's.

General :: LG Optimus L3 (E400) Restoring CWM To Stock Recovery

Nov 6, 2012

I had done several things before (rooting, installing cwm recovery through rom manager, etc) until my phone got bricked, and tried a lot of things until i have flashed Cyanogenmod, and it woks just fine (and its cool), but I have changed it back to original stock firmware using KDZ flasher. Now, I tried to boot my phone in recovery mode (by holding volume down+back+power button) and CWM recovery is booted. I want to get rid of it and restore back my original recovery, because, i suppose, it was the reason why my phone was bricked before (i wiped and formatted the system and updated the firmware using fOTA, and the result was a CWM bootloop)

General :: Optimus V Recovery Loop With Flashing Error (Can't Find Update Script)

Jan 9, 2013

So I was having a problem with my Optimus V (Virginmobile) and I couldn't send or receive texts. I did a factory restart thinking it would work but then found myself at the recovery menu. When I try to flash it says E:cant find update script. When I try and flash CM7.2RC1_VM670-BobZhome-052012 it installs and when I reboot i get taken back to the recovery menu.

In short; My Virgin Mobile Optimus V is stuck in a recovery loop that I am unable to get out of due to an error while trying to flash ROMs/ Custom Recovery.

The error reads at the end of all attempts: E: Can't find update script.

General :: THL W8S - IMEI Invalid After Few Flash

Oct 23, 2013

I bought recently my thl W8S, and I was experiencing some troubles with the battery charging (taking 10 hours) and my GPS connection.

So I decided to flash it via CWM. But I'm very new in the flashing and all this stuff. I tried a lot of things to get CWM , even thing I didn't know.

The problem of my IMEI came out atfer I installed this : [URL] ....

The recovery installer apk, I just click on it and when my phone rebooted, I didn't have any access to my SIM management, no more coverage of course.

I tried the *#06# and my 2 IMEI are just marked as "INVALID".

Since yesterday I tried few different operations to get if fixed but nothing is working.

I tried to use the engenering mode (menu CDS, Network information) and send the AT command with the IMEI but I got an error message : AT command is failed to send.

Then I tried to recreate the MP0B_001 file with some tools I downloaded. And I put it in the right folder (/data/nvram/md/NVRAM/NVD_IMEI/MP0B_001) instead of the old file. I reboot my phone, still the same trouble.

I can't find the stock rom to try to flash it with Odin ..

So, like I have been reading all throughout the forums, sometimes other users have ran into the issue where the IMEI is 0.

Now, I hear injecting the IMEI is an option, but I am unable to find a method how to do this.

I attempted to follow a video where a user goes through several steps, such as this video


but I am stuck on step 2 where I have to dial *#7284#. I get the error message "Connection Problem or invalid MMI code" so I cannot proceed any further.
