[LG Optimus G (International)] mansoor3131:
First of all,thank you for your kind reply. Now i am giving you the complete picture what happens.

My phone LG Optimus G (F180L) is rooted and unfortunately i unistalled the applications Google Play tv and Play movie. WiFi is on and a message comes that software update is available. I allow to update. When the update finished, my phone reboots and stuck on LG logo. I Google and found the method below:

http://xdaforums.com/showthread.php?t=2249500

Now TWRP 2.5.0.0 installed together with LGNPST TeenyBin

From the fastboot screen, it shows

PRODUCT NAME mako

VARIANT mako 32GB

HW VERSION rev_11 (&¤)

BOOTLOADER VERSION MAKOZ10f

BASEBAND VERSION N/A

CARRIER INFO None

SERIAL NUMBER xxxxx

SIGNING production

SECURE BOOT Enabled

LOCK STATE UNLOCKED

I could access the TWRP built in.

4) Then I used ADB to push ROM to the internal SDCARD and recovery to install. But this method failed – tried several ROMs which all gave errors initially. I discovered that the install script pointed at “e975” in(ro.product.device and ro.build.product but the phone reports “geehrc4g”

This is the output in recovery.log when trying to flash ROM

Warning: No file_contexts

script aborted: assert failed: getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975"

assert failed: getprop("ro.product.device") == "e975" || getprop("ro.build.product") == "e975"

Following the advice(from internet) of changing the script by Deleting the ‘assert’ line in the script, then

E:Zip signature verification failed: 1

Error flashing zip '/sdcard/thinkingbridge.zip'

Updating partition details...

To ensure working environment I tried to flash gapps which worked perfectly so connection and recovery must be functional.

5) Now turning to: ”[GUIDE] How to UNBRICK your Optimus G - security error, bootloop etc”

I used the method described and downloaded the appropriate KDZ file etc. etc but flashing gives this log:

10:05:58 : Unpacking KDZ

10:06:05 : KDZ file extracted

10:09:27 : ResetStartInfo() Call End

10:09:29 : ===FINISHED===

At the point where KDZ file is extracted the phone reverts from download mode to recovery which is probably why it fails.

I read the thread at xdadeveloper forum "[Q] Unbricking LG Optimus G e975 - using LGNPST, TWRP, ADB". Do all the things suugested but nothing happens.

I tried every method both on Win 7& XP but same error.Results are attached (see attachment)

During flashing it goes from download mode into fast boot screen and in device manager,Other devices: "Android?" is shown. When i try to install the drivers, it only picks the Google nexus 4 drivers and show the device "Nexus 4 bootloader interface".

I am so worried because i buy the phone two months ago. I cannot afford .What is happening?

1) In recovery mode it shows that it it is a MAKO product. What is this mean because every thing i know is that it is a LG Optimus G F180L and after searching Google, i find that MAKO is a Nexus 4.

2) Is TeenyBin and LGPNST creates problem? If yes, what to do?

Where is the problem and what the problem? I am nearly to wheep.

How can i solve this problem? Please help me and reply me. I tried every method suggested on internet.
