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 P970 Optimus - Incoming SMS Encoding

Jul 3, 2012

I have LG P970 Optimus black. I know this problem is about a lot of devices and a lot of regions. We are using latin alphabet with some special characters. like "ı, ş, �, ğ, �.." when someone sends me a text message with this characters,

It is normally shown in cm7 and its based roms.
It is normally shown in lg roms which are released for turkey
but it is shown like one space in different lg roms.

For fixing it, what can i do. Is it about message apk? or about some libs?

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

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

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

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 :: 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 :: Restore Boot Animation To LG Optimus L9

May 20, 2014

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.)

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 :: Android Boot Sequence And Backup / Access To Boot / Recovery Partitions?

Oct 4, 2012

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.

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 :: LG L35g Optimus Logic Pause In ClockWorkMod Boot Loop

Jan 25, 2013

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.

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 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.

General :: CWM Recovery Build - Black Screen?

Jan 11, 2014

I'm trying to build CWM for the HP Slate 7 Plus, but both touch and non-touch builds coming from the CWM Builder and manually built builds give a black screen with a few white lines when booted into recovery. The stock recovery.img I provided to the builder is valid because people were able to reflash the same recovery.img via Flashify with no issues, which is the same method used to flash the defunct CWM. I don't have the Slate 7 Plus, so I can't test things myself

The best I can do right now is debloat, deodex, and pre-root ROMs, as well as install more system apps.

General :: Bricked Arc S Stuck On Black Screen At Boot Up

-> I downloaded the CM9 anzu for my arc S
-> Extracted the files
-> Used fastboot to flash boot.img
-> And then: fastboot reboot

Instead of the FreeXperia splash screen welcoming me.. i was given a black screen.. The phone does turn on.. but then there is nothing. No splash screens. nothing.

Is there anyway to boot straight into CWM?? recovery?? Did i brick my phone for good?
