LG OPTIMUS L5 Secure Boot

Getting bored with the lack of support for this phone I understand its a brand new phone but its unfair that so much development goes into other phones like the sgs III etc which are also brand new phones.

The security on Boot and recovery is just ridiculous. I have also sent LG emails and just recieved the same computer generated reply that everyone else got, I have signed the petition which is more people can join in hopefully might help.

There must be away we can disable the security without having to contact LG or have someone spefically from LG to have to help us out. This phone is great but is just lacking that availability of tweaking this phone to its full potential.

I understand why LG and other companies would do this, they expect that the way they have the final firmware setup on the phone is what your expected to be happy with. An Im sure if your a new android user, or dont know much about android platform or phones in general this phone would seem perfect but for us that know a little more and the possibilities that this phone and all android phones have, it gets a bit frustrating not being able to bring the L5 to its full potential.

Feels like i should've chose a cheaper and lower quality phone like the Hauwei Sonic just becuase of the possibiliities and endless custom roms these lower quality phones have to offer, so how come an old crappy cheap phone can get more support from developers etc then a supposebly good phone like the LG.

GRRRR

Guys, please help me! I have trouble with my LG E612 (Vietnam).... My date&time sometimes goes wrong. once per 2 weeks or once per month, like today, it happened again... I can't tell how exactly my problem to the technician at warranty center. Because they can't see the time goes wrong when I bring it to them. So

1) Anyone had the same problem?

2) Can I use stock ROM of LG E610 to upgrade my phone? As I use KDZ to upgrade ROM from UK to my other phone LG E400
[Optimus L3, L5, L7 General] stevewq:
I have had a similar problem with my LG E612 (Australia) every time I turn off my phone or restart it my timezone gets changed, I have to go in and change it manually which really shouldnt have to do have never had that problem on any other android phones I have had in the past. Using the latest only available firmware for Australia V10C Boost.

L5 multitasking speed

My L5 with stock ROM is awfully slow when changing apps. Multitasking sucks. Is it the same for your L5's?

It has like 400MB of available RAM and I it's always using the most of it (which I think is normal, since is the way Android enviroment is used like), nevertheless, app changing is quite slow. Sometimes when I press the home button, it would take about 8 seconds to fully load Go Launcher (happens the same with stock home screen app). It almost never keeps applications paused in background as it requires more Ram to launch the front application, thus it destroys every app that goes to the background.

Is a custom ROM going to solve this problem?
[Optimus L3, L5, L7 General] dfreake:
there are no custom roms ....yet
[Optimus L3, L5, L7 General] stevewq:
Question

Just wondering if anyone knows, the first page of this forum I downloaded the Stock Rom ICS 4.0 link which is a zip file which more a less looks like a rom you would flash in cwm recovery or etc if we ever get that chance :( just wondering if anyone has downloaded it an if they installed it how did they do it?

Thanks

Does any one else have problems to share the 3G internet connection via Bluetooth?

I just can't do it. I used to do it with my older phone, an Samsung Galaxy Europe.

I just want to share via bluetooth the 3G with my Tablet... Wi-fi Thethering is just not energy friendly, it will drain more battery.

Does any one knows an app that take over control of bluetooth? I bet this limitation was implemented by my celphone carrier. Tecnically it is ilegal to share your internet connection in here =/

Somebody using Tasker on this phone?

I tried setting up so it turns into silent mode from 10pm to 8am, but it still makes sound. I wanna put it to only vibration, either on call or notification.
[Optimus L3, L5, L7 General] toby913:
so do we have any updates regarding our petition to disable boot security???
[Optimus L3, L5, L7 General] pinkflozd:
I dont expect the secured boot to be taken off so quickly... i think that quite a few months will pass if they ever take it off
[Optimus L3, L5, L7 General] toby913:
That kinda :thumbdown: despite the the lack of support it is a great phone
[Optimus L3, L5, L7 General] dfreake:
yeah when the we hear that lg locked the bootloader it drop our hopes
[Optimus L3, L5, L7 General] gustlik:
For me it looks good even on 144 :P Maybe it is because i completly removed some stock apps and installed some from my own choice. Lock screen have some brighter belt on right side but i didnt find anything else.
[Optimus L3, L5, L7 General] toby913:
i changed DPI to 200 and now my lckscreen is smaller then the rest of my screen, is there a possibilty we can change the size of our lockscreen?

Hello. Any news about unlocking bootloader or method to instal CWM Recovery ?
[Optimus L3, L5, L7 General] pinkflozd:
Pinkflozd E610 Rom

ok guys, i've been able to do a few things on our phone eaven though its locked

* init.d support (scripts added: module loader, bash, ssh, ext4 tweaks, darky zipalign, sqlite optimize, sysctl load, lowmemorykiller)

* cpu schedulers: SavagedZen, InteractiveX, MinMax, Lagfree

* cfq tweaks

* ext4 tweaks

* bash shell support

* native ssh through dropbear

* lowmemorykiller tweaks

* busybox 1.20.2

* nano editor

* deadline disk scheduler

* added CM9 ringtones

i think that is almost all we can do for our device atm

i will make a .bat to install this "Rom" in a few days
[Optimus L3, L5, L7 General] toby913:
Great news mate, :D

May I ask is it possible that you add cm10 bootanimation ?
[Optimus L3, L5, L7 General] pinkflozd:
we can add whatever animation we want, we need to get the images scaled to our resolution and thats all

edit: this is the bootanimation i use, i will make a script to change the bootanimation too
[Optimus L3, L5, L7 General] toby913:
That's cool :D are you able to change the default launcher as well?

edit....

if you want to i can test the .bat file as well
[Optimus L3, L5, L7 General] MrCzAjNiK:
Brick

Hi guys I have a problem.

Let's start from begining.

I rooted L5 and i was want to install thoose test cwm builds.

All was fine, I mean "secure boot" error showes up.

Then I want to instal cwm with "Rom Manager" Phone hangs and i pull over batery.

Then after power it one phone just hang at LG logo.

I am able to enter fastboot mode naighter adb too.

I was traied to extract our system.img from kdz with succed but the file is too large for fastboot (~500mb)

So I read again whoole thread and find similar problem and sollution. But...

I extract kdz to cab and cab to dz with "dzextract.exe" and get "system.img.ext4_0".

i was tryied to flash it with or without -w and in other order combination with no succed.

Still LG logo is displayed.

PC can't recognice it diffrent than "ADB Single Sonar interface" or sth like that.

KDZ didn't see phone in any case.

LG's Update Utilyty cant recognize it too. Neighter in software resurection mode.

I cant push system with adb because I cant remount system. Strange.

I have some knowadle about android. I was compilling my own, flashing and editing.

All my previous devices was able to get back from that "brick" witch is no actually brick xD.

So there is my questions:

Is you guys know any idea to unbrick it?

Is there any way to "slim" system.img that I can flash it via fastboot?

Any oder ideas?
[Optimus L3, L5, L7 General] fastupro:
looking forward for this. cant wait to test it. great job, keep it going.
[Optimus L3, L5, L7 General] ldeleeuw:
I'm not sure if it will work, but you can try it. I hope you made a backup of your important files.

Turn off your phone (if needed by pulling out your battery and putting it back in). Press both volume buttons and at the same connect to your PC with an USB cable. A LG logo and some message will appear. Run "LGMobile Support Tool" and go to "customer support" > "recovery phone". Follow instructions.

Good luck
[Optimus L3, L5, L7 General] igerup:
Stock DPI seems to be 160. At least if you have E612f like me. Anything lower and we won't get the benefit of the displays native 480x320 resolution. Even so, I noticed that setting it at 150 and 162 results in a screenshot at 319x479. :confused:

I'll experiment some more.
[Optimus L3, L5, L7 General] MrCzAjNiK:
Negative, phone just hang on like usually. I think I should wait for development for e610 will be in advanced stage.

When someone bypass secure boot(witch I thing is not so secure) then I will be able to flash at last recovery, than just custom room.

Or I can send it to lg service. With fresh, stock system.img.ext4_0, recovery and boot' flashed from fastboot mode.

That's probably all solutions anavaible at the moment :/

***EDIT***

About DPI, when my phone works at stock I used "DPI Changer" application from Play Store.

It works fine. I don't know how it works, or did it simply change DPI param in build.prop or in other way. But who cares...
[Optimus L3, L5, L7 General] igerup:
I edited build.prop with SystemTunerPro and rebooted. The only visible difference when setting the DPI to 170 was that the status bar drop down menu handle thingy (you know, where the provider/ISP name goes) was off-center. Nothing else. I edited it back to 160, though. I don't really want to brick my third :laugh: L5...
[Optimus L3, L5, L7 General] fastupro:
Hello. Can anybody tell me how to move apps and games to microSD card?

I've created 2 partitions on sd card (ext2 and FAT32, both primary). Link2SD and other programs like that don't work (even Directory Bind). Or maybe i just set up something wrong. Please can anybody tell me how to get it working.
[Optimus L3, L5, L7 General] MrCzAjNiK:
You can just use native app2sd from applications manager.

Choose app you want to move to sdcard and tap "move to sdcard" xD.

You can also use "Super Box" app from play store. Then when you install something, notiffication about abilyty to move this app will appear.

---------- Post added at 01:29 PM ---------- Previous post was at 12:55 PM ----------

ldeeleu your solution works:)

I tryied it secound time with success:)

Thanks! +1 for you:)

First sory about reply after reply, but its not related to previous posts :)

Anyway why that solution isnt added to first post yet? :) thats important because we have now a way to unbrick.

About custom roms and recovery.

L5 as we know have secure boot. But on xperia devices most knowed way to install cwm is to run batch script witch push recovery files into /system partition and boot it from there using chargemon hack i think. Ill try to ask someone from fxp if we could boot they way too.

Anyway there is secound solution.

Is l5 nearly same as l3?

l3 have cm9 so if it was compiled for stock kernel,

we can use their build to boot it.

And why we cant push whoole /system and create symlinks with script by adb? Bootloop or what?

We must try all ways... try to push it and logcat why it doasnt want to boot.

Last option is to bypass the lg's secure boot.

The guys from l7 have same troubles as we have.

If they manage to do sth im almost sure we can- do it too.

Need moore research.
[Optimus L3, L5, L7 General] toby913:
These are great ideas. You seem to have experience with android :D

Would be really great if we manage to get something out of your suggestions :rolleyes:
[Optimus L3, L5, L7 General] MrCzAjNiK:
Kexec seems to load new system to memory just a while after stock kernel pass boot process.

This is how guys from moto d3 managed to flash roms and even custom kernels, recoverys into their devices.

Xperia cwm boot didnt work here.

We must use kexec metod i think.

But i dont know if we have suport for it in our stock kernel.

Ill continue research about this because that can be only way to manage something wihout unlock from lg.

Anyway guys from l7 find that it is possible to dissable secure boot by changing few lines in kernel config. No need to compiling from sources in that case. We can do it by use 2 perl scripts on linux machine.

L7 stops at flashing it because they have compleatly locked bootloader(as we?).

But we're able to flash images with succes via fastboot so our problem is secure boot(or i'm wrong?).

It's complicated a bit:p

Edit:

http://linux.die.net/man/8/kexec

Afternoon ill try to looks into our current kernel config to find if it supports kernel.

Then unsecured_boot.img->cwm->custom.

Ill try my best.
[Optimus L3, L5, L7 General] toby913:
I can see that:D please continue you research. I just read the first post, does this mean that the Rom will be stored on our sd card? Which then means without a big sd card no Roms?
[Optimus L3, L5, L7 General] imobileface:
but i think there are better choises than LG optimus
[Optimus L3, L5, L7 General] hezron4k:
Tried this but now my phone won't boot past the LG logo so adb can't see my device. Any tips on how I can get into fastboot mode to reflash the system partition?
[Optimus L3, L5, L7 General] MrCzAjNiK:
You cant flash system via fastboot mode bacause file is too large.

Download kdz updater and flash .kdz from first post by entering in this phone caind of "download mode".

To do that just press and hold both vol+ and vol-, then connect usb cable.

For future read whoole thread. Cause i was fighting with that too...
[Optimus L3, L5, L7 General] pinkflozd:
those lines that the guys talk in the L7 section are just to enable adb root by default not for secure boot

and we cant do anything with kexec because its disabled in the stock kernel :S
[Optimus L3, L5, L7 General] MrCzAjNiK:
Actually i want to post that right now, but you were fastest:0

So no options for us. But where secure boot is located then...

And the main question is how it work...

What part of partition they check... and wich files are depend of it.

It must check something...

Strange is that we can flash partitions using fastboot... so bootloader is not locked atself but something check is files are sock.

Anyone was tryied to push /system dir of l3 cm9?

What about if we flash custom kernel? It will show secure boot error?

And last, how to debug that... bootstage is before android booting process so logcat is usless.

I think we need some xda hero to manage that.

The problem is l5 isn't popular device...

Abandon all hope.
[Optimus L3, L5, L7 General] pinkflozd:
hey guys, got a problem, forgot to backup my recovery img is anyone running the V10G firmware and can make a backup?

i have only a backup of V10B that doesnt work

dd if=/dev/block/mmcblk0p17 of=/sdcard/mmcblk0p17.backup bs=4096

thanks
[Optimus L3, L5, L7 General] MrCzAjNiK:
For what you need stock recovery now?

Its usless, if you just wanna wipe try fastboot -w.
[Optimus L3, L5, L7 General] pinkflozd:
i got the stock recovery from toby, i needed it because the old recovery i had backuped was giving the secure booting error, without the stock recovery working you can't update your system with kdz

but i came to the conclusion that every recovery is version specific so probably the secure boot check is located somewhere in the system
[Optimus L3, L5, L7 General] igerup:
Update v10j-SEP-20-2012 (only about 18 megabytes) is out, but I'm getting error 0x13E. Is it because the phone is rooted? Does anyone know?

Never mind, the phone didn't download the file properly. It's >260 MB so no wonder there was an error. Anyway, I had to re-root afterwards. The o4xr method works with the v10j update

so there's no need to worry. I'm in euroland so the update might not be available everywhere, though.
[Optimus L3, L5, L7 General] hezron4k:
Yeah, sorry about that.. saw the vol+, vol-, connect-usb option immediately after I posted my comment. But I used LG Update Utility instead, didn't know kdz updater could work in that mode given it didn't detect my phone in all other modes I tried before. Thanks anyway, hope someone else learnt something new from this.
[Optimus L3, L5, L7 General] toby913:
I did the same update. But mine had only 15mb and I did not need to reroot
[Optimus L3, L5, L7 General] MrCzAjNiK:
This is OTA update? Can someone provide me to flashable file of this update? Its located in cache.

Or adb logcat it and attach log when you click update.
[Optimus L3, L5, L7 General] toby913:
well my update was OTA.. tell me how i can get to the cache, because i can't find the folder

:rolleyes:

EDIT....

i stumbled over this what do you think guys, could someone with experience test this with our phones

Car charger

The Problem:

I was try some aftermarket car chargers but noone can charge my phone. I was phone to LG Greece and noone technician knows what the matter. The only thing that they said was "Your car charger has problem, not the phone"

The Solution that i find:

Inside the connection cable has 4 wires. Usually red for +5V, black for ground, white and green for Data. All car chargers has only 2 wires. Red and black. If you make a sort circuit between white and green wires the phone start charging. Use this cable ONLY with car charger.
[Optimus L3, L5, L7 General] MrCzAjNiK:
Noone of those tools can be usfull at the moment.

We need to run cwm first. Thats the main goal at the moment.

System/cache, better way will be logcat.
[Optimus L3, L5, L7 General] toby913:
Okay thanks however my phone is rooted and I don't have access to system nor to cache, what file browser are you using?
[Optimus L3, L5, L7 General] Quacktop:
I installed v10J from Europe open (full stock rom) and now NFC doesn't work, neither I can find it in the settings. Previously I had v10H from UK (full stock rom) and NFC was working fine.

My L5 is a e610.

Anyone else has the same problem?
[Optimus L3, L5, L7 General] toby913:
I never used my NFC but I can activate it. However as I never used I cannot confirm if it works
[Optimus L3, L5, L7 General] Quacktop:
If I activate it from the notificationbar it won't get blue and in settings under Wireless & Networks -> More, there is no option to activate NFC.

What version are you running?
[Optimus L3, L5, L7 General] toby913:
Same version Europe stock Rom because I bought it unlocked
[Optimus L3, L5, L7 General] igerup:
NFC works for me. I had v10f before.
[Optimus L3, L5, L7 General] toby913:
where can i learn or read those kind of commands for my phone?
[Optimus L3, L5, L7 General] MrCzAjNiK:
You cand find info about fastboot and adb tools on cyanogen's mod wiki.
[Optimus L3, L5, L7 General] toby913:
Okay thanks
[Optimus L3, L5, L7 General] toby913:
hey guys could anyone with firmware version 10j try to use a self build recovery maybe with the update they disabled the secure boot and now we are able to build a custom recovery for it

all thumbs crossed
[Optimus L3, L5, L7 General] Cyn3t1X:
I'm really asking myself in what way my E610 is different from yours ... I got a stock (unbranded, unlocked) EMEA market phone, and your method doesn't work on it.

Here's the output of running root.bat:

DON'T TOUCH THE DEVICE OR UNPLUG WHILE ROOTING!

REBOOT

Imo, this CAN'T work at all, since /data is a read-only file system, so any attempt to delete stuff from / copy stuff to /data/* is ultimately bound to fail. I mean, being able to do what root.bat tries to do is THE GOAL of rooting the phone, but sure not a method. If it should work at all, the script would need to write to a (rw) file system.
[Optimus L3, L5, L7 General] igerup:
Did you try with copying the IS11LG_SystemBackupTest.signed.apk to the phone, installing it, starting it and without closing it, rebooting the phone?
[Optimus L3, L5, L7 General] Cyn3t1X:
Thanks bunches! Your hint pointed me in the right direction. I guess the reason why it didn't work for me before was that I have a task killer installed that shuts down apps before a reboot. So perhaps it also killed the SystemBackupTest app. Once I had the task killer uninstalled, SystemBackupTest kept running, and the procedure worked.

Again, thanks bunches ! Got my E610 rooted now :)

hi guys,

sorry for digging up and old thread, but, i just got as a present today a LG L5 610 phone and has all kinds of crapware installed on it and was thinking if it's posible to simply erase everything and reinstall ics 4 from scratch...

any help would be greatly appreciated... :)
[Optimus L3, L5, L7 General] toby913:
if you root your phone you can just uninstall all that bloatware you don't like

for a guide on how to root your LG l5 go to first page of this thread
[Optimus L3, L5, L7 General] bogolino:
ok...thanks toby...but i think i'm freacking stupid...cause i cant seem to root the phone... got to the 3rd option on rooting the phone, and left the hole night open that root.bat file to run..and it just show's me what you can see in the attached file...clearly i'm doing something wrong...but what?! :-/

ps: this is my first time on rooting...so please be gentle... :(
[Optimus L3, L5, L7 General] toby913:
no problem mate :D i am as new to as you are ;)

please try this method: http://xdaforums.com/showpost.php?p=30491581&postcount=43

i think it's more complete and this is the method i used and it worked. please check before starting this root method if you enabled the 2 options in step 3

here they are:

On the phone open "Options -> Security" enable "Unknown sources"

In the "developers options" enable USB debugging

note: when you have the phone in english it can often be easier to find those options, that's what i think

when i had my phone in portugues i couldn't find the usb debugging option because the name in my language has nothing to do with debugging.

don't forget to open the installed "IS11LG_SystemBackupTest.signed.apk" which you installed some steps before.

good luck
[Optimus L3, L5, L7 General] igerup:
And don't forget to leave open, as in do not shut down the "IS11LG_SystemBackupTest.signed.apk" before you reboot the phone.
[Optimus L3, L5, L7 General] bogolino:
ok...so ...phone is in english...checked the two options...there ok...

but the question is... how long do i have to "wait until the script is executed and the phone will reboot"??? left it all night and nothing...
[Optimus L3, L5, L7 General] toby913:
should be 5 minutes
