[GUIDE] How to UNBRICK your Optimus G - security error, bootloop etc

For whatever reasons (improper rooting/flashing, power outage during updating, freezing/removal of LG bloatwares or simple bad luck etc), if you bricked your Optimus G and is stuck with a Security Error or in a bootloop, fear not, as long as you can put it into Download and Recovery Mode, all is not lost.
I got the korean version of the (almost) Optimus G (Optimus LTE2, f160k) and ran into the same security error problem that happened out of the blue.
The steps that I undertook below resolved the problem for me and has been proven to work on Optimus G by fellow members.
http://forum.xda-developers.com/showpost.php?p=34516791&postcount=29
1) Download the latest KDZ from LG's server for your phone via the app below (kudos to the creator)
http://www.mediafire.com/?cgeb6o5osy2yl9c
2) Make sure you have LG United Drivers already installed, otherwise download from below
http://www.mediafire.com/?82nt1aeh04aqa3m
3) Download LG KDZ Updater
http://www.mediafire.com/?sj5y073xal03ntw
4) Download the manual adb wipe batch file
http://www.mediafire.com/?ru7erfxsz7p7s3p
5) Put your Optimus G into Download Mode by switching it off, attaching the usb cable to the phone, holding both the up and down volume buttons at the same time and lastly inserting the usb cable into the computer; wait for the drivers to finish loading if doing it for the first time.
6) Unzip the downloaded updater zip file and run KDZ_FW_UPD.exe. Use the settings below
Type: 3GQCT
Phone Mode: CS_Emergency
KDZ file: navigate to the folder which you have saved the downloaded KDZ from the step (1)
Click Launch Software Update and wait for the flash process to finish
7) Your phone will restart itself when IParam = 90 is displayed and proceed slower until you see IParam=1 again (which signals the end of flash, you can safely exit the program then and remove the cable from the phone). If phone boots up normally, congrats, skip the steps below and proceed to use the phone as per normal.
However, this most probably will not be the case for newer Optimus-es, as the data partition somehow wasn't wiped even when KDZ-ed, remaining 'dirty', thus causing bootloop or security infringement.
8) If the phone is stuck at the booting up LG/Telco logo, you will need to manually wipe the data partition.
9) Force the phone off by holding the power button for appx 15secs.
10) Put the phone into recovery mode by holding the volume up and home button concurrently, then press the power button. Let go of all the buttons after you see the LG logo on screen for the 2nd time and the screen goes blank thereafter (backlight may still be on). The phone will kind of reboot and then enters recovery mode. Repeat the process if you did not get it the first time.
11) With the phone in Recovery Mode, connect it to the computer, wait for the drivers to load (if doing it for the first time), unzip the wipe batch file downloaded earlier from step (4), double click on wipe.bat to execute the wipe command.
12) Your phone will auto reboot when wiped and (hopefully) boot as per normal.
Hope with this simple guide fellow members will feel safer when rooting or removing non essential LG wares from their Optimus G.

Tried this, however the phone get stuck on a bootloop. It's stuck on bootanimation. I also tried to clear data with the adb wipe files but i end up with a phone stuck on that

Bell E973
I have E973 from Bell and it's been bricked since sunday after renaming couple of system apps.
I am trying to follow the instruction above but i can't download KDZ file with LG firmware downloader bc it just would not take my SN.
Error msg is "unsuccessful in connecting to server orphone infomations is wrong!"
Could anyone upload KDZ file for Bell E973 somewhere on the net that i can download?
It would be much appreciated..

Go here, replacing <yourimei> with your actual imei (just numbers, nothing else), it'll spit out a bunch of text including an address with the kdz.

Don't include the <> characters with your imei, I just put those there to mark where the IMEI goes
Also, your IMEI should be 15 digits, and I've only used this on my computer, so I'm not sure if it works on mobile browser or not, and if that's how you're trying it.

2nd thracky's view.
would recommend u do it on the PC, use the app, enter your model E973, enter your imei (15 digits, usually means omitting the the last 0 or digit), shd be able to download your KDZ.

did u wipe in recovery mode?
can you put your phone into download mode again?
if yes, try the whole process again?
as long as your phone can still enter download mode, all is not lost, even if this method does not work,
good luck!

He couldn't get into recovery at all, that image he posted was what happened going into recovery.
I think he mangled his partition table, and I feel like KDZ wouldn't necessarily repartition everything based on my experience with tools for other phones like Odin for Samsung phones, where you explicitly have to tell it to repartition and give it a file to dictate the layout.

learned something new, thanks
KDZ-ing of LG's phones of late seem to be not as 'thorough' as previous, it used to be the be all and end all; or maybe i didnt mangle my phone bad enough
has he tried upgrading via LG's update tool instead?
he may need to KDZ an older version first (if available) so LG tool can sense an upgrade is necessary, and hopefully, it is intelligent enough to repartition if one is necessary.
also, LG's update tool has in-built recovery/repair option, not sure how that works though, worth to explore?

Yep update tool was tried, recovery wouldn't work either. He wound up exchanging the phone anyways

I could not find the KDZ file

wish to know if there are any other ways to get the kdz?
I've asked some L-01E onwers, they replied that normal ways do not work japan version
look for help THX

Question for Sprint
potatohead said:
6) Unzip the downloaded updater zip file and run KDZ_FW_UPD.exe. Use the settings below
Type: 3GQCT
Phone Mode: CS_Emergency
KDZ file: navigate to the folder which you have saved the downloaded KDZ from the step (1)
Click to expand...
Click to collapse
Question, on the Sprint version of this phone, would the type be CDMA?
Also, do you think anything else would be different?
*edit* Also, when I try to download the KDZ file, it is instead a .CAB file that has an .wdb, .wdh, and a .dll file inside.
Am I supposed to rename it? convert it?
Thanks!

I can not get it to download the KDZ file either. Is there anyway to post a link for a direct download?

This should not be used for the Sprint or AT&T variants, please see instructions for restoring with LGNPST in the respective forums as we have .tot files for both AT&T and Sprint.

Thank you. I have seen that but I do not know how to flash the TOT file. I have downloaded that, but do not know how to flash it.

I wouldn't work for me until I added 1 more step
First of all, thanks again to the poster and xda in general...y'all freakin rule.
I couldn't get this to work for the longest time, though I knew that these valuable instructions were the key to fixing my device.
The difference between total failure and absolute success for me was making sure to run "msxml.msi" in the KDZ updater before running "KDZ_FW_UPD.exe"
If you're stuck, try that!!!
Thanks once again for helping me fix my device!

if someone could find a valid method to HW ENABLE the FM Radio on korean variant , i'm grateful .
And to use internal DMB module to working with DVB-T signal (for Europe sure)

What wolfgard said would have been great but is it even possible?

Flash this ROM successfully via TWRP, then reinstall the app+data zip created from Titianium Backup Pro (previously under Korean Stock ROM), then delete all bundled Chinese apps, now using happily without any problem!

What? It is a update.zip file. no need to further decompress it.

The file is a 1.9GB .bin file.. I tried to change the file extension using root explorer but twrp can't see any .bin extensions..
bad Download?
I did utilize the mirror link....

Any idea why this is happening and how I can get my phone to boot normally?
ADB is not recognizing my device...
./fastboot devices shows ???????????

Can't get ADB OR FASTBOOT to detect the device... I imagine the backup I made it gone from the phone. I didnt move it to the PC...
How can I get the phone to be detected so I can try to push the necessary files??

It must be write like D802 or something else..
I tried with L02E but can't get me anywhere..
Until I install the correct drivers from lg website..
Next It recognised my phone model and my IMEI without my help..
After that it success download the property firmware and install it flawlessly..
Hope that helps..
Ok thank you!!
The only problem is I can't seem to get phone recognized on my Mac or PC using fast boot or adb. I have installed the 3.10 and 3.8 lg drivers with no success, ontop of my imei showing all zeros..
I am at a loss, getting close to giving up lol...
Thanks for all the tips
---------- Post added at 08:09 AM ---------- Previous post was at 07:26 AM ----------
I have switched USB cables, switch ports.. Did get it on COM4 - No Dice
I have tried 3.8 LG drivers and newest 3.10 LG drivers.
I have uninstalled and resinstalled drivers.
I have downloaded multiple KDZ files with no luck as they freeeze at 49%
I have powered the computer down, phone down, reinstalled drivers, then reconnect phone with no luck..
Continually showing as L02E..
When in download mode the Number above "Rooted" always changes, what is that number?
When I do get download mode going in route to 47% it always says D802 in the box below ( with the "Rooted" text )
Do I have a shot to fix this or am I actually bricked???
Other than download mode it boots only to fastboot mode ( two lines of white text ) but no devices are detected with fastboot or ADB.
Sighhhh... Giving up for now!
Thanks to everyone for trying to assist.

Seem there's something wrong.
After I've done to install update.zip , then restart system. I stuck in this.
Fastboot mode started
udc_start()
And I've plugged in USB cable I got this.
Fastboot mode started
udc_start()
-reset-
-portcharge-
-reset-
-portcharge-
Then? I can't boot my G2 at all. Any idea????
p.s. I got back to Recovery Mode by using Power+Volume down and restore form SD card.
still want to flash this ROM but I don't know how.

Unbricking LG LU6200

DISCLAIMER: Not my work, Tutorial followed from : http://choimobile.vn/threads/unbrick-lg-lu6200-ghim-cap-qhsusb-khong-thao-may.8448.html
Hi
I have been using LU6200 from last one year, and I loved this phone. I have tested many roms, and was using 4.4.2 CM11 rom. Then I installed an app from Play store, which modified the kernel, and booted my phone.
At this stage, my phone was totally dead, no screen indication, no light, no sound. Only one thing, is that when I connect my USB cable to computer, my computer try to install driver and also make sound of USB connection and disconnection.
So below are he steps which I have performed
MUST: KEEP YOUR PHONE ATTACHED WITH USB CABLE TO PC
Download the following files
http://pan.baidu.com/share/link?shareid=547069&uk=3071575749 <-USB DRIVER
http://pan.baidu.com/share/link?shareid=547084&uk=3071575749 <-Softwares

Winhex - Forensic or Specialist version full not evaluation and registered. I have found only one version [WinHex 17.SR1.rar] which worked for me, not remember where from I downloaded this
Follow this tutorial http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/ to run your OS in Advance mood where we have to disable DRIVER SIGNATURE ENFORCEMENT
When you have booted into windows after disabling driver signature, install the 1st Link file,
Install the Driver, when Installed it will show a COM Port installed, QUALCOMM one
Install the Softwares, default path will be C:\Program Files (x86)\Qualcomm\QPST\bin\
You also have items in your start menu, so run
1, In the "Start Menu" -> "QPST" -> "QPST Configuration" RUN This
2, Select the tab "PORT" and click "Add New Port ..."
3. A new window will open where the COM port which is newlly added to your system will be listed, select that port and add that
{
"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Keep that running
4 Go to the "Start Menu" -> "QPST" -> eMMC Software Downloadapp " RUN THIS
4.1 Uncheck, Program MMC Device
4.2 Click Browse, it displayed me PHONE ATTACHED with QUALCOM details near the top right of the image, where No ports Active is written
4.3 Check Search Path 2 and Browse to you files, where you have downloaded 3rd file. Which contains one hex, one img and mbn file
4.4 In the Flash Programming File name, enter the name of hex file
4.5 in boot image, enter the mbn file name
4.6 Click DOWNLOAD
at this point, it mounted me a 200kb drive which was not formatted. I have formatted that, and then kept this program running in the background as well
5. Winhex
5.1 Run Winhex, Make sure you have forensic version, and also Full version ,there are evolution version too, but that will not work. FULL VERSION and FORENSIC/SPECIALIST License is must
5.2 In Winhex, go to "File", "Restore Image", Change the file type from "WHX" to "Raw Image container"
5.5 Select lu6200.img from the 3rd file downloaded
5.5 Now it will ask for Target disc
5.6 Carefully select the QUALCOM, or else you will be formating your own HDD
5.7 In this window click OK
Now it will start giving your some strange, nasty warnings, just keep pressing OK, and Yes Continue Ok, etc etc
When that will finish, you phone will auto restart.
Now you may have to reflash that, or wipe it and install the KDZ ICS engineer version again. As right now My phone is in boot loop but I guess that can be fixed.

If you can, it will be very thankful, because my Korean friends had LU6200 bricked.

I am following all the steps. eMMC software showed that it QPST server not running. I ran eMMC download tool with Admin rights and that problem was gone.
Now when I Press download button this error pops up showing Image Download Failed. Cookie(if present) not received.
Is there a solution for that?

[GUIDE]Desire 816 update guide (platform.xml error fix guide)

finally my desire 816 has succesfully updated!
after 3 days of whole heaps of trouble updating due to my phone has been rooted and modded
now i'm gonna leave a guide to my own version of fix. btw my 816 is a5_ul. suppose the updates work all the same
1st off u must do what others has already mentioned. remove supersu. go into supersu and then settings, scroll down to until u see "full unroot". click it and wait for it to complete. then restart your phone.
my 1st problem was with 1.54.707.2. thru a lotta searching i it was the recovery that was causing the problem. so according to many guides that can be found in this forum was to flash the recovery found in ota 1.60.707.3. and the ota starts working perfectly
then my 2nd problem starts while installing 2.34.707.1 ota.
like many of the newbies stated wen they updates they see a red triangle exclamation mark error. if u guys hold volume up + power, u will see the error msg.
what u will most probably see is "/system/etc/permissions/platform.xml has unexpected contents". according to some thread i read in m7's forum page it was due to cwm modded the sdcard write permission. so i asked around and thx to junior member sumancvb i found the replacement platform.xml file
the best way to replace your file is thru twrp recovery. copy the platform.xml file to your sd card, go into twrp recovery, click mount, tick "/system". then go into advance, file manager and use it to copy the xml file to /system/etc/permissions/. replace the original platform.xml in this folder.
after replacing the platform file, i came across ANOTHER freaking error while updating 2.34.707.1 ota. this time, it was "/system/xbin/nc has unexpected contents". thru another extensive searching and asking, thanks to sumancvb again i get the replacement nc file.
same as the trick above use the provided "nc" fle, get into twrp to replace the "nc" file in /system/xbin/
then VOILA!!! my phone was succesfully updated! YAY. many thank to the forum for guides.
now i can enjoy the beauty of lollipop (maybe)
also i might upload the ruu for 2.34.707.1

i dont know how to tell u but thanks very very very very much for the nc file

Re
Thanks dude for the links! Thank you so muchh man! I try this as soon as i got home

don't thank me, thank sumancvb, he was the one who gave me those files in the 1st place

Thank you , but one question
What about NC file
should we extract or placed whole rar file?

First extact then place individual files
/system/xbin/nc
/system/etc/permissions/platform.xml
And don't forget to fix permissions

It works! Thanks guys

just go into your phone settings -> about phone -> and check for updates. let it start downloading and don't install after it completes, instead navigate to internal storage -> downloads and copy the zip file out

You guys are great.

LG G3 D851 Hard Bricked after installing D855 firmware

Well I messed up while using TWRP and I'm unable to enter download mode or turn on the phone, my computer recognizes it as a LG COM port, but I can also recognize it as a Qualcomm HS-USB QDLoader 9008 by short circuiting. I tried the BoardDiag method, but I get "Failed during loading flash programmer".
And when I use LG Flash Tool I get "Model Information Check Fail!"
I really need help!
