I'll give you a little pre-story.
Short version:
I have CWM recovery on android 4.12 but when I try to flash either PACman Rom or CM It gives me assert: failed getprop error. After removing the first line of the updater script in the zipfile I don't get the assert error, it just states
Finding update package...
Opening update package...
Installing update...
Installation Aborted.
Long version:
Initialy I was running Android 4.04 (ICS) with CWM recovery. I decided to flash the PACman rom(http://forum.xda-developers.com/showthread.php?t=2388267). I did the following.
1. Rebooted into CWM recovery.
2. Did a factory reset.
3 Wiped Dalvik cache.
4. Flashed ROM
5 Flashed Kernel
After completing these steps I rebooted my phone to find a "Security Error" message under the LG logo. It would automaticlly shutdown after 20 seconds. So what I initially tried was to flash the 10G KDZ which didn't work out because the LG tool is ****. However the 20B KDZ did work (which is Android 4.1.2). After the flashing had completed my phone booted normally. I was able to root my phone using this guide http://forum.xda-developers.com/showthread.php?t=2173465. I was also able to install CWM recovery. Now the following problem is this when I want to flash the PACman rom or the CM ROM I get the following error assert failed: getprop("ro.product.device") == p760 || getprop ("ro.build.product") == "p760" E:error in (path to zipfile) (status 7) Installation aborted. I got around that by removing the first line of the of the updater script. I don't get the error but it just states "Installation aborted".
Thanks in advance.

Is your phone booloader unlock? You must unlock your phone boot loader before flash any custom rom.

Well I assume since I have CWM Recovery that my phone's bootloader is unlocked. Correct me if I'm wrong.

If your phone bootloader is unlocked and you also remove assert model check line from installer, you shouldn't get that error status 7.
Please try to make sure that your phone bootloader is unlocked by boot your phone in S/W update mode. The bootloader unlock text will print at the top of that screen.

I can confirm that it is unlocked. The text in the upperleft corner reads "Bootloader Status: Unlocked".

If you still unable to flash any custom rom please try to flash stock kdz or use LG mobile support tool to recover your phone. Once my phone is in strange condition, I can flash custom rom but I cannot boot it (My bad, I use wrong update script when I test my rom). My phone always stuck at LG logo. Flash kdz, restore CWM and flash rom don't help. The last thing that make my phone boot up again is LG mobile support tool.
BTW if you phone model is not P760 you should restore your old baseband by flash you original kdz. (You flash P760 to unlock your boot loader right?)

Well the problem is that I can't flash the stock 10G KDZ because the LG Mobile Support Tool only allows me to install 20B KDZ. Your question could be interpreted in two ways so I will give you two awnsers .
Q Why did I flash my p760?
A Because after flashing PACman rom on android 4.0.4 I got a security error
Q How did I unlock my bootloader?
A I first rooted the device. Installed CWM recovery, then did adb reboot oem-unlock
So the question is how do I flash 4.0.4 KDZ if the LG mobile support tool does not allow me?. Or how do I resolve the ROM installation issues?.
Thanks again

For flashing ICS
In JB rom offline flash program cannot detect your phone in S/W update mode. Most people stuck at about 15% and the program told them that their phone is not connect. If you want to flash 4.0.4 ICS kdz you should
- boot your phone up (if it can boot up),
- connect usb cable and put your phone in LG software mode.
- Do an offline flash again but select DIAG instead of EMERGENCY. You phone should reboot into S/W update mode automatically. After that it will get pass 15%.
But If you cannot boot your phone up, you need to flash you phone model ICS u-boot and x-loader via fastboot. After that offline flash program can detect your phone in S/W update mode.
For rom istallation, I'm sorry I don't understand why you cannot flash custom rom. Maybe your download is corrupt? Please check file md5 with rom uploader.

I did the above but I get a page error(only with the 4.04 kdz). When my phone was bricked I had the same problem thats why I flashed 20B. Thanks for your time.
Hey Guys!
I'm currently having an issue i would like to share:
I'm trying to fix my brother's phone, is an LG P768. He tried to root it (first time ever) and apparently he flashed wrong Xloader and Uboot. The phone still works but i am unable to access SW Download mode or Fastboot (Required for Flash stock rom again). I've read many threads where you can flash those files again but the same issue I need to flash them via Fastboot or SW Download mode. obviously i need to install the drivers in my computer to do this procedure but there is no way to install them if my phone doesn't boot properly into those modes.
Model: LG p768
KDZ File: v20a_00
4.1.2 Stock Rom
Hopefully someone can help me.
thanks

Hi guys. I'm not really sure if i'm in the right place to ask this question but i managed easily to root, unlock bootloader and flash cwm recovery so i thought when this thread helped with all of above (and thanks for that!) maybe someone can answer me how to (and can i) do a sim unlock of d620r ?
I'm having an LG phone for the first time. Other androids i had (mostly samsung and sony) i was able to unlock quite easy finding online tutorials but with this one i'm stuck cause i don't seem to be able to find any help on google or here on xda.
Any info would be very appreciated

Hi good Job!
I have Two questions.
Can i upgrade my twrp Version with flashing the zip file in twrp?
Which Bootloader version use cyanogenmod 12?
Thank you!
A few additional info for the D802 variant:
-You don't NEED to change boot loader if you're fully on stock unless:
--You plan to use AOSP Lollipop
--You use any JB based ROMs (they should say in their respective threads for the D802)
-If you stick with the KK boot loader, only flash BUMPed flashables (they should state if they use this method)
-I recommend to use Blastagator's TWRP as it has thermal protection that stock TWRP doesn't have
-Only flash ROMs/any other flashables while the phone is cool
-Most ROMs can use the KK modem unless stated otherwise
Correct me on any misunderstood/incorrect information

1. You should be able to
2. You should be on the JB boot loader, we don't have the 12B one, that's for another variant

Yes. If you installed AutoRec and u are able to open recovery, you can flash via older twrp. It is no problem

Ok, good. I liked your tutorial, pretty informative.
Hello, i'm stuck at this step :
"3. Update bootloader. (IMPORTANT!!! U ALWAYS NEED UPDATE BOOTLOADER WITH VERSION ROM WHAT YOU ALREADY HAVE, IF YOUR ROM V20H, USE 20H BOOTLOADER, IF YOU HAVE 20D, THEN USE 20D BOOTLOADER OR UPDATE YOUR DEVICE TO 20H!!)
Now u need becareful, because it is easy way to brick device if you will not perform tutorial.
-->> Download v20h bootloader <<--
Download bootloader to your memory storage in device, and open flashify, press Menu button and Reboot Recovery, when it will reboot to TWRP, press INSTALL and select bootloader v20h zip file in path you downloaded it. "
Edit : i flashed the rom without KK bootloader and it worked
-> I Was on 20H. I rooted, installed twrp, updated twrp. I've flashed 20d KK bootloader and now, secure booting error
I have access to download mode. What can i do do boot normally ? (i know i could probably flash a kdz but i don't really want to)
i cannot enter into the twrp by pressing the vol down + power, it just ask me whether i want to format, this means i still do not have twrp ?

Well if you cant enter your recovery or system then you have to flash kdz.

You already flashed TWRP right? If so then you need to confirm it twice with the power button. It says like format data/factory reset but it will boot into the custom recovery.
please help me...i have a lg g2 d802 32gb model ..its a traded phone...when i got the phone it was running 4.4.2 kitkat the phone was rooted bt there was no suprrueser app i installed the app and then i flashed recovery with autorec now whenever i open my data or wifi and use my phone for some minutes my screen becomes unresponsive is it due to the jellybean bootloader that the autorec installed or something else please help me...
Recovery combo gone
The thread seems like dead now, but maybe I get help .
I flashed 20H and now there is the recovery combo, when I try pwr + volume down it simply reboots . The recovery is instaled, but I only can access it from software (that now is corrupted, so, soft brick).
Wrong combo

You're not soft bricked, it's just that key combo changes in 20H, new combo to enter recovery is vol down + power key, As lg logo appears, release keys and press vol up + vol down and you can easily access twrp
and i ran intro bootloop.. help!
I'll update theard soon to aosp/lollipop support, bootstacks explains etc.

Hi! I'm not new to xda, but I just don't get this method http://forum.xda-developers.com/g2-mini/development/bootloader-unlock-t2827748. I don't even know if i have to do this using PC or g2 mini.
I remember rooting, unlocking bootloader and flashing recovery on my lg l7. It was like i download 1 zip file on my PC, unpack it, connect the phone and run 1 file that did all for me. Is there something like that for g2 mini? (D620r)
Hey, i cant uderstand this method too, please tell me if you have found a solution for flashing a recovery in a way i could understand
