Hey everyone!
Can somebody with an LG Optimus L5 running V20C please upload a backup of your bootloader ? I forgot to do it and I need one now .
You can do one by using :
Code:
adb shell
su
dd if=/dev/block/mmcblk0p5 of=/sdcard/emmc_appsboot.bin.bak

HELP!! Lg optimus l5 keeps rebooting after unlocking bootloader and installing CWM

my lg optimus l5 E612 keeps rebooting itself after the media scan. this didn't happen untill i unlocked the bootloader and installed CWM. i have tried to wipe the cache, the dalvik cache and a factory reset in CWM but still kept rebooting. So I restored the original bootloader and recovery than done a factory reset and that stopped it. I downloaded the the ulocked bootloader from a diffident website and tried doing it again but still did it. how can i fix it??
The solution !!!!!!!!!!
Enable USB debug (before your phone reboots).......... very fast!
first
you must have patched you phone with recovery (mmcblk0p17) and boot (mmcblk0p5) partition
This file is extracted from the russian firmware....... is the bootloader!!!
I try this process with my phone (lg e612f)...... and no more reboots
copy the file to the sdcard
docs.google.com/file/d/0B-im6Vo1WjAEV1phbWRLOXIzX00/edit?usp=sharing
run from ADB
adb shell
su
dd if=/sdcard/immcblk0p9 of=/dev/block/mmcblk0p9
reboot recovery
enjoy...... your phone is unlocked!!!!!!!

When i'm start to play some game like Temple run it cannot last for a few minutes, apps start to crush like android proces has stoped, google play has stoped etc... and than sudenly restarts itself... then i have to remove baterry and live the phone to "cool" for a while, and than i can turn it on when everything works normaly util next longer using... this is happening even when using other apps like skype for a little longer...I have tried to flash new software, even to instal prerooted software and do a factory reset through CMW, dalvik, cache, fix permisions but nothing helped, always the same... HELP!
I would try this method above but the LINK IS BROKEN...
Thanks in advance
Hello,
I have exactly the same problem with my Optimus L5 after unlocking the bootloader. Any idea where this problem comes from and how to solve it?
Did you use the exact bootloader for your model?
See this post
Thanks for the answer,
I used this OL5_1.0

Also according to Android my phone is E610, but on the back it's written E610/E612F, so which one should I try?
Last problem, since I have installed Cyanogenmod there is no more "charge only", I don't know if it's really important though. I will try to have yours work.

In android the model can be changed by modifiying one line of build.prop, so i'll trust what the back of the phone says...
To me, while connecting usb is the same on pc... nevermind the "charge only"
I was about to commit suicide because I couldn't get adb working. But finally I managed to enter those 3 commands in the integrated Terminal Emulator, having previously installed the file for E610:
Code:
su
dd if=/sdcard/emmc_appsboot.bin of=/dev/block/mmcblk0p5
reboot
And it worked. That was quite hard because I only had 2 minutes between the boot and the reboot. Thanks for helping me. :good:

I've been in the lg-g2 channel freenod, and have been said that i must use linux to restaure my partitions using dd commands.
If someone could help me by providing me the exact files i must push into my phone and whn exactly i must push them.

[Q] LG Optimus L5 (e610)

Hi Everyone... I Want To Ask How to Install Clock Work Mod Recovery Without PC, And How To Install The newest Or How To Update CWM Recovery. Thanks
Do you have rooted your phone?
Do you know someting about bash / shell / bat files ?
I have rooted phone, but I'm don't know about those shell/bash/bat files...
In some tutorials to install CWM requires you to have a unlocked bootloader and adb to flash things. With root you can do that using Android Terminal Emulator and doing the commands that comonly are in bat files that calls adb
the common should be
dd bs=4096 if=/sdcard/bootloader_unlock.bin of=/dev/ (something)
of course you must have the files extracted in sdcard (the same with recovery)
Ye... I have unlocked bootloader, ok, i try this...
I prepared a thread for this after see this thread. http://forum.xda-developers.com/optimus-l3-l5-l7/general/l5-guide-root-unlock-bootloader-install-t2938943
