Security Error corrected!

Thanks for this info! I was able to update the SW from the LG Support Tool program but I had to switch to another computer to do it, and after several tries it finally took.

For this LG-P769 I had to hold the volume up button with the battery out and it went into the SW update mode on the phones screen. The update stopped after 33% update and I had to disconnect and install the battery, start the phone and let the Security Error extinguish, then plugged the USB cord back in and click the retry button of the tool, then it updates. Yes!

Note, wait until the phone reboots to the normal operating screen even though the tool says its done. This tool approx. 2 more minutes.

The phone is no longer rooted but it kept all the original apps except "Superus".

Not working for me, any help?

I have an LG-LS970, and I've made it to the point where the recovery software was downloaded and extracted, but something is causing an error and not letting the process finish. I assume this is the faulty ROM on the phone, since my phone is bricked from rooting and deleting Google Play apps (I was stupid and thought they weren't important to have). Any ideas?
[LG Optimus L9 P760, P765, P768, P769] Eliminater74:
If you had the recovery software installed you could of installed the gaps. Zip files through it.

Please help i've been at this for 2 days

I moved a boot.img file to my Metropcs LG optimus L9 lgms769 and now I am stuck at the security error. I rooted the phone but did not have the bootloader unlocked. I have tried the update tool and it stops at 4%, when I can get it to work. I haven't either understood the other methods mention or something, idk. Anyway, I would really like to get my phone working. Can someone please give me a good way to do this. I have the V10E_00.kdz file already. Thankyou

I already have the latest version but need to repair

Thanks for the instructions! I followed the steps and everything basically works but once the phone is in software upgrade mode, the LG tool just says "Your device has the latest software available from the LG Mobile Support Tool" and it doesn't install anything.

What happened is I rooted my phone and removed one too many system apps, now it won't boot up anymore. How can I get this tool to reinstall the same software I already have? Do I need to wipe it completely? Please help me out, I'm afraid I'll make it worse if I try anything else. :(

Thank you so much! I totally overlooked the recovery option in the tool. 30 minutes later and I have my phone back working perfectly. So happy! :good:

I took it to the T-Mobile store this morning and all they wanted to do was sell me a new one, saying the phone was dead. I owe you. Can I buy you a beer? Seriously, if you have PayPal I'll do it.

Is it working? My phone is in S/W Upgrade mode, but I don't see any upload bar anywhere

Background:

I originally had CWM and custom rom install on my phone. I decided to install a new rom, but the installation failled and Aroma installer kicked me out of recovery. I have no way re-entering recovery, so I used Smart Flasher and the correct ROM to flash the phone back. And now I'm stuck at Security Error.

Can't maintain S/W

When I open S/W upgrade mode and plug into the computer, it always shuts off the whole phone after a few seconds. The LG software seems to recognize that it's plugged in because it says "connecting" while the phone is on, but then it gets shut down and it stops.

[LG Optimus L9 P760, P765, P768, P769] dihcar:
yeah fixed it. you must use LGMobile support tool, download it and install it on your computer, open it and click update drivers, choose the right driver for metropcs lg optimus l9 and install it. now you you have to enter s/w mode on the phone to do that take battery out to turn it off and put it back press and hold volume up while plugging it to your computer don't release until I switch to s/w mode ( or may be volume down I don't quiet remember, try both).

once connected let the tool detect it then press "option" then choose "update and restore" now kick back and let it do its magic until it finishes rebooting.

hope that helps good luck.:good:

Thank you SO much for this guide to fix LG L9 Security Error!!!! MetroPCS would not fix my phone even though I pay extra for service each month, and the insurance wanted me to pay $100 in a deductible which I was never told about, so they could replace my phone with a lesser phone. It took quite a few tries, but finally I got your instructions to work on my computer. I am a tech novice, and really appreciate your straightforward instructions, along with some additional comments by others who shared their experiences.

Warning!

Everything seemed to be working fine -- I was able to get it into S/W Upgrade mode. Started the recovery process (by the way, you DO need a battery in, at least with the P769, or else the recovery process will halt when the phone tried to reboot).

Recovery process gets to %100, no problem at all. Now the phone is COMPLETELY bricked. Black screen, can't even get it into S/W recovery again. Connecting to USB just creates a USB connect/disconnect loop, and Windows says it is unrecognized.

Good ****ing support of your phones there, LG. What a load of ****. So glad this isn't my phone -- I was smart enough to stay with Nexus devices. Haven't had a single problem with any of them -- no Security error bull****, no stupid bloatware.

I have followed steps mentioned and installed Mobile Support Tool, then installed USB driver and then went on to connect phone to PC using mircousb cable.

I have tried all 3 options, 1st pressing VOL- and then inserting microusb cable. 2nd pressing VOL+ and then inserting the cable

and lastly by pressing both VOL keys together and then inserting usb cable. but then none of the things seem to be working , as phone is not getting into S/W upgrade mode. :(

Hello,

suddenly appears on my LG L9 (LG-P760) after the launch "LG Secuirty Error" and no further work.

what can I do?

LGMobileSupportTool I loaded >>> B2C188AppSetup.exe

Driver was installed for Windows 7 >>> LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.1 0.1.exe

if I now take out the battery press vol+ button and connect usb to computer comes shortly "S / W Upgrading Please wait while upgrading" then connects the phone in the support tool and then the connection dissolves immediately and the display is black again

if I let go of the button it stays black

if I continue to hold the button, the display will come from time to time and then go away again

I even managed to download the V20O_00.kdz from time to time (via the menu item "reset the upgrade error") but then the tool crashes after downloading the file and after unzipping it

would be really great if you could help me here

Thank you!!!!!

Howdy, I posted a new thread regarding my own problem with an Optimus L9 Security Error. The LG Mobile Support Tool tells me my device can only be updated OTA, and also that it is fully up to date. I have no idea what to try next because all of the guides that describe how to flash the stock MS769 ROM assume I can access my Developer Options in my Settings, but the device is of course stuck booting to the Security Error screen.

I get 2 days without swithching it off too. This is kinda dissapointing since sony claims 3-4 and even 6 days lith light use.

I use my sw2 with sgs2, i wonder if thats relevant to the battery life.

Another thing ive noticed, I get almnost no diference in bat life when disabling vibrations, changing brightness and stopping notifications. Basicaly i get 2 days with heavy use and 2 days with light use.

Maybe this means most of the battery is drained via BT?

[Sony Smartwatch] arizal:
battery is Android build dependant

Here is an update.

I've got a replacement since the first sw2's screen got ugly dark spot.

The new one also had about 2 days of battery, then I updated to newer cyanogen version and voila, 3-4 days of battery easily achieved.

Then I changed my S2(i9100) for Moto G. The moto g has original kitkat and the battery life on my sw2 droped to ~1day. phone's battery was also about a day, without sw2 connected it can easily do 2-3 days! my S2 running cm11( kitkat 4.4.2 ) was fine.

Soo, obviously the battey life is very much rom dependant. sony's software works works well with some roms and not so well with others!

I just got the watch yesterday and it automatically updated it to the newest firmware.

Battery life is great and I really love the "usefulness" of it!

The double-tap to wake doesn't work though, even when it's set in the settings.

Instead, the watch does wake up when I pick it up... which is quite handy actually, but is it meant to do that?

What is the point of having a smartwatch if you turn off Bluetooth and can't receive notifications?

I can understand turning it off at night but during the day, it defeats the purpose....

I get around 2-3 days and that's good enough for me.
