I have encountered similar problem before dude. I suggest you use another cord in connecting your phone to PC. or you may also try connecting it to another USB port.

Anyway dude, activating/deactivating tethering on your mobile has nothing to do with it.

If it still doesn't work dude, I presume it's ROM-related problem. Why don't you try this cm-11 for your device.? Here's the link.

Security error LG P714f

Can anyone help me? :(

I have a LG (Optimus) L7 II, P714f, Brazilian version, that is stuck in a boot loop. Sometimes, the message "Security error" appears upside down, sometimes is the screen of Android update. I can't do the hard reset pressing the buttons Home + Vol(-) + Power. The device never received any root, and any recovery have been installed. Basically, it has the stock version (V10A, according to LG Mobile Support tool, Jelly Bean 4.1). I've tried to do the Recovery Update through LG Mobile Support tool, without success.

What else can I try?
[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] Scurzmann:
HAve you tried to use the LG kdz updater but to no avail?
[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] guibgomes:
Yep. I tried with the KDZ updater available in this post: http://xdaforums.com/optimus-l3-l5-l7-l9-ii/development/kk-kk-kdz-p710-root-t2950532

I also tried with the official kdz file (copied from the folder during the update) using this tool, and with the version available in the post. Again, no success.

I'm almost believing this phone is dead. :rolleyes:
[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] Scurzmann:
Nope not completely. LG phones are likely unbrickable.

Try again with the Lg mobile support tool. It's an official flasher so it won't let you down if you use it correctly.

Download the tool and your device driver attached below.

Install the driver.

Turn off your phone completely.

Now run the tool (b2cappsetup.exe)

Press and hold vol down then connect your phone to pc to enter download/emergency mode.

Wait for the program and make sure it recognizes your phone model and current firmware version. Otherwise nothing will work.

Now click Start!

Or If it says you're already on the latest firmware click upgrade recovery.

The whole process usually takes about 1 hour depending on your internet speed. So be patient:)

Tool http://www.softpedia.com/get/Mobile-Phone-Tools/Others/LGMobile-Support-Tool.shtml

Driver http://singledrivers.blogspot.com/2013/11/lg-optimus-l7-ii-p710-p715-usb-driver.html?m=1
[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] guibgomes:
Well, I did exactly how you said, but I got the same :(

As shown in the attachments (it's in pt-br), the tool recognizes correctly the phone model (1.png), and starts the upgrade with kdz v10f version - the latest version of Jelly Bean available for my country (2.png). When hits 95%, the phone restarts, what is normal. But, just a sec after powering on, the LG logo fades and it restarts, falling in bootloop again.

Then, I tried the Recovery Upgrade (3.png - I think this time is v20a version, Kitkat). Again, it hits 95%, the phone restarts, the LG logo fades and I got a bootloop again.

I'm very sure that the battery is full, or with good charge, but when I put it to charge, the charging screen doesn't appears.
[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] Scurzmann:
Happened to me a couple of times before with my L3 ii, L5, and L7 as I got through with hardreset.

If the s/w upgrade is gone complete but your phone didn't boot itself you only need to do a hard reset to recover it.

Press and hold the Volume down key + Hot key/Quick button (on the left side of the

phone.) + Power key for about 8secs.

When the LG logo appears on the screen release the power key.

Then release volume down key + hot key when the LG logo disappears.

And wait....:)

Memory wipe

Hello there, I updated my LG P700 to the v20c 4.1.2 JB version. After that, I couldn't find a way to root it, but found Framaroot app and succeeded with it. I got a little cocky how easy it was and downloaded ROM Manager. From it, I chose the CWM installation option and the window said it was a success. Now I wanted to install a new Rom (I planned to install this one: http://xdaforums.com/showthread.php?t=2552148 do you know a better alternative?) However, when I clicked to reboot into the recovery, only this little error appeared - "Secure Booting Error! Cause: Boot certification verify." in the left uper corner of the screen. Nothing worked, so I took out the battery and after turning the phone on, I noticed that all the internal memory got factory reset or something like that and it is just a blank fresh android - all data was lost. Long story short: flashing recovery from ROM Manager caused the wipe of the memory. What happened?

Hi there!

I don't know where add this post, then i get it here.

My GF have LG E610. It's not good phone(****ty hardware i think). I try to install there any ROM's. Every rom was after one-two days slow and callphone was not usable. I remember using Skernel too with newest CWM. So now i must ask my question.

What i should to do if i want to clean all data and flash custom rom? Can you recommend me the best ROM for this phone? Must be total stable. Apps what she are using: facebook, instagram, snapchat, messenger, whatsapp, emoji keyboard and quiz game(?).

Please help me, sometimes i think she is with her neighbor in bed when not responding, but no! Her phone just froze! @_@

Sorry for my bad english, but i'm doing what i can ;)
[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] Scurzmann:
Okay, as for Kitkat we only have two choices of somehow stable ROMS for our L5.

Either this: http://xdaforums.com/showthread.php?t=2919279

Or this: http://xdaforums.com/showthread.php?t=2519448.

I recommend the latter as it's built with later sources than the former one.

First back up all your user apps and their data with titanium backup so that you can then easily restore them after the new ROM installation.

Put the ROM.zip in externalSD

Now reboot to recovery

Mount system

Mount cache

Mount data

Wipe cache/dalvik

Wipe data/factory reset

Format system

Flash the ROM

Flash skernel final

Reboot

Reboot to recovery

Flash gapps(pico)

Wipe cache/dalvik

Reboot

Ps. Do not use fb messenger it gluttonously consumes RAM and drastically lags your device. Better uninstall it and use the fb chat re-enabler instead. Here : http://xdaforums.com/showthread.php?t=2934179

[Optimus L3, L5, L7 Q&A, Help & Troubleshooting] Scurzmann:
Actually it happens after every reboot, you just have to wait for the back button and menu button to light for a couple of secs, then they should work. If not, just keep rebooting they should eventually work. Just a reminder that you may encounter screen freezes at times with those ROMS. Just then press the power button for about 10secs to reboot your phone.

But if you can't really help it, you may have to switch to pecan's ROM. It's actually what I'm using now. No known issue other than the screen freezes. But no big deal ROM is fast and snappy after all.:)

Have you tried to manually enter fastboot: remove battery, hold vol+ & vol- while plugging in USB.

LG emergency download mode is similar: remove battery, hold vol- while plugging in USB.

I've had problems with the e610 getting into these modes, sometimes it takes several tries before it works.

If B2CAppSetup.exe didn't give any error while flashing the .kdz, then try manually cold booting with the USB unplugged, letting it alone for 15-20 min. (pull the battery and replace if it's stuck at the boot splash screen). But it seems like it takes forever after flashing .kdz the first time, and some ROM/kernel combinations have been known to freeze at the boot splash when USB plugged in. If this is the case, you will have to use the various button combinations to get it into the boot mode you need.
