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.

My mom has a LG Optimus L9 p769. I'm trying to boot the phone into recovery mode by holding down the + volume button, the home button, and the power button. The phone will not boot into recovery mode. The phone works perfectly fine, I just can't get into recovery mode.

I am using sony ericsson x10 mini mobile phone. I want to install custom ROM cyanogen 7 gingerbread. But I am facing problem while booting this in recovery mode. I have tried the following.
downloaded custom rom for xperia mini and copied in to sdcard
installed ROM Manager Premium (not purchased, downloaded from google search and it is working fine)
installed root explorer S1 tool
Rooted from superoneclick
downloaded xRecovery and copied into system folder
Flash tool - showing bootloader unlocked, and dont know how to flash phone.
msm7227 - used for unlock boot loader
I have rooted my phone successfully, all above things did successfully, when i am trying to boot my phone into recovery mode then it is not boot in that mode instead it boots in normal mode. What I am doing when phone starts and sonyericcson appears then i continuously pushing button many times but it boots in normal mode. So what I have to do to boot my phone in recovery mode. I have read and tried many guides in your forum but nothing works.

Today my phone started continuously re-booting itself. Only gets to the HTC screen and then re-boots. I have done multiple battery pulls with no results. I cannot boot into recovery either, tried that many times as well. My only option is a screen that I have not seen before that asks if I want to clear all data and then reset the device.

I have a Nexus one and I have made a bit of a mess of it when loading a custom rom. Previously I'd rooted (without unlocking) the stock (2.2) rom before loading Cyanogen 6, later Cyanogen nightlies and finally eViL-NXSense-v1213. I was rather enjoying the last one but had severe stability issues which I think was due to using Titanium Backup and restoring data. I was in the process of re-imaging to eViL-NXSense-v1213 after clearing the SD card, data and various caches when something seemed to happen to the recovery image. I can get into the boot loader but if I select Recovery it shows the Nexus One logo indefinitely and doesn't respond to the power button being pressed, the same happens if I turn it on from cold.
Is it possible that the recovery image has somehow been corrupted? If so what can I do to restore a recovery image that will enable me to install a custom rom. I would prefer not to unlock the boot loader but will do it if necessary.

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
Code:
sudo adb start-server
adb shell
su
dd if=/dev/block/mmcblk0p9 of=/sdcard/boot.img
dd if=/dev/block/mmcblk0p17 of=/sdcard/recovery.img
exit
exit
adb pull /sdcard/booty.img
adb pull /sdcard/recovery.img
Initialized the project via mkvendor.sh
Code:
mkdir ~/android/system/vendor/LGE/vee7e
mkdir ~/android/system/device/LGE/vee7e
~/android/system/build/tools/device/mkvendor.sh LGE vee7e ~/boot.img
cd ~/android/system/
. build/envsetup.sh
make -j4 revoveryimage
make -j4 recoveryzip
I now have the CWM Recovery, and I inserted in my phone
Code:
cd ~/android/system/out/target/product/vee7e/
adb push recovery.img /sdcard/recovery-cwm.img
adb shell
su
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
Code:
[4380] -------------------------------------------------------------------
[4380]
[4380] Secure booting Error!
[4390] Cause: boot certification verify
[4390]
[4390] -------------------------------------------------------------------
In the attached you will find my recovery and the error message.

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

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?

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.

I own an LG Optimus L9 from T-Mobile. A few months ago, I rooted it and installed the Jarvis boot animation, complete with a Jarvis start up sound.
I started having issues with my phone, so I performed a factory reset. However, the boot animation is still the Jarvis one. I need to send the device in for a repair, and I need it back to the original boot animation (one where there was white and pink squares that did a wave animation, along with the T-Mobile jingle.)

I accidentally flashed the wrong recovery onto my LG Optimus V. The phone is stuck in a boot loop and I am unable to make a selection in recovery. How can I flash the correct version of clockwork mod without doing it through the phone?

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."

I'm trying to root my T-Mobile L90 as per this guide: [URL]
But T-Mobile has locked out Recovery Mode so that button combinations and "adb reboot recovery" do not work.
Any way that I can remove this restriction or force recovery mode?

Im really stuck, my phone is rooted, is deleted something that i didn't know was important(with titanium backup pro) and it failed everytime to restore, so i tried to reset my phone to default setting.
But guess what, my phone boot but stop at "the application settings(process com.android.settings) has stopped unexpectedly. Force close )
I got a back up of the original rom that i made with clockworkmod so i would like to restore it. But i cannot boot in systeme recory mode
i tried:
vol up/down + home + power = no result
vol up/down + back + power = yellow and it says "emergency mode!! but nothing happen"

I try to understand android boot sequence on my JB (under CM10). I found some docs and there should be specific partitions (boot, recovery, system, cache, data).
My understanding of the boot sequence is now:
A) normal boot:
1) Power ON ->
2) bootloader ->
3) boot-partition where i flashed the kernel aka boot.img ->
4a) system-partition with the OS (libs, UI, etc) where i unpacked over CWM my customROM.zip ->
4b) data-partition, where i unpacked google-apps.zip and installed all the apps ->
4c) cache-partition with user data
B) recovery boot (adb reboot recovery):
1) Power ON ->
2) bootloader ->
3) recovery-partition with CWM where i may unpack all the .zip stuff to proper partitions, or restore from sdcard, etc.
Is this correct? I wonder, because i didn't installed CWM into recovery-partition. It cames from install of CM10 (fastboot -i 0xfce flash boot boot.img), so it must be in boot-partition and not in recovery?
So, next confusion: i looked up to /proc/mtd and i don't see neither boot nor recovery partition here:
Quote:
# cat /proc/mtd
dev: size erasesize name
mtd0: 19000000 00040000 "system"
mtd1: 00600000 00040000 "appslog"
mtd2: 06580000 00040000 "cache"
mtd3: 1a400000 00040000 "userdata"
I did a backup with CWM and loocked the data. There aren't boot, and recovery backups:
Quote:
# ls -lha /sdcard/clockworkmod/backup/2012-10-04.18.49.55/
d---rwxr-x 2 system sdcard_r 4.0K Oct 4 18:56 .
d---rwxr-x 3 system sdcard_r 4.0K Oct 4 18:49 ..
----rwxr-x 1 system sdcard_r 1.6K Oct 4 18:54 .android_secure.vfat.dup
----rwxr-x 1 system sdcard_r 54.6M Oct 4 18:55 cache.yaffs2.img
----rwxr-x 1 system sdcard_r 360.2M Oct 4 18:53 data.yaffs2.img
----rwxr-x 1 system sdcard_r 212 Oct 4 18:56 nandroid.md5
----rwxr-x 1 system sdcard_r 214.6M Oct 4 18:51 system.yaffs2.img
#
So, i think i didn't understand the boot sequence and partition schema corectly.

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)

My stats:
LG L35g Optimus Logic from Net10
Running Android 2.3.6
It is rooted.
Clockworkmod 5.8.4.5
Okay, first off this is totally my fault that this phone is stuck.
I was inside the About menu of android and saw there was an update for 2.3.6
So, stupidly, I decided to select it. It downloaded the update, rebooted, and then wound up at the clockworkmod recovery screen.
I tried the "reboot system now" option, but it just reboots back to the recovery screen.
I have used the "wiped data/factory reset" option. I've wiped the cache partition and Dalvik cache.
I didn't backup the stock rom, so I found these two roms for the l35g from here:
AA51
Stock (user modded version)
I used the restore option in recovery mode, but the "Stock" rom above didn't take. The AA51 rom did install fully and told me to reboot. I did, but it still went right back into the boot-loop!
I think the solution to this is to fix the boot-loop issue. Would Zengarden or Xionia work? Then, if so, I need a version of it to work with the l35g.

I recently did this and now I'm unable to run custom ROMs on my Optimus One:
>Downgraded baseband (so as to install ICS ROM by DaxElectro
>Then installed the above mentioned ROM and I loved it!!!
>But later found some limitations of it. (The SIM that I was using didn't let me access internet over this ROM. Other SIMs worked fine). I thought of telling to the developer about it.
>So I installed original, official Gingerbread 2.3.3 firmware V20c (India) again, through the backup created using Clockworkmod Recovery and also upgraded the baseband.
Later I wanted to show my friends the ICS ROM as they all wanted to see it. But before flashing that ROM, I wanted to try mik_os's Cyanogenmod on my phone and test it.
>I installed that but this ROM gave a boot loop error (of course I had again downgraded the baseband) I thought it is buggy so I removed and flashed DaxElectro's ICS ROM again, thought it would work fine as before.
But, now even this ROM is giving the same error!!! I'm very upset as I'm not able use it now!
How to fix this???
Yes but my official firmware is working fine and I posted this using that only.

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 xionia_cwma_12518.6.zip 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.

I'm new to android but just used the guides at this forum to root my LG Optimus V. I was wondering if now that I have root there is a way to install a boot password similar to the one I have on my computer. Before it loads the operating system, the BIOS asks for a password. Is there any similar functionality for android?
Also, is this possible on other devices even if it is not on mine? It's one of my favorite laymen security measures.
