[Verizon LG G3] stewbuntu:
UPDATE 6/19

So I installed CM12 12 or 13 require 23C, 24B, or 35 (TWRP 2.8. has those versions mentioned in the fail error script)

I kept getting the boot error and so I started over and flashed KDZ's in order from 10 to 23c

With the 23c you can use the one click program to root but also have the bootloader that CM12 OR CM13 needs

After root the error code did not show up

After bustbox the error did not show up

I used TWRP manager app to install 4 different TWRPs, all gave a boot code error and would reboot to CM or stock but obviously something was wrong

So then after research I found others that had trouble and used Autorec to solve the issue

UPDATE 6/15 - Bootloader error?

It says:

SECURE BOOTING ERROR!

ERROR 1003

So I updated to 24B and I have CM 12.1 running. I did notice a boot error "error 1003" right before TWRP opened to install the ROM and just before the cyanogenmod boot screen popped up - Is that going to be okay, everything seems to be working fine?

How I got the ROM installed

1.) Flashed 24B using KDZ flash tool and file

2.) Root - Only king root from here worked (click unknown sources, also Google stopped the install so I had to out it in airplane mode and open the apk): http://xdaforums.com/lg-g...3129197/page84

3.) Installed busy box, TWRP, SuperSU asked to update the binary.

4.) Download cm 12.1 files tot the TWRP backup files

5.) Reboot into TWRP recovery

6.) backed up phone so you don’t have to get root again

7.) wipe - factory reset - wipe dalvic and cache again

8.) Installed CM 12.1 and rebooted system

Original issue: Failed ROM flash on 12B and TWRP3.0

See recovery log below

The only thing I can think if now is that I need to use a .tot and not the kdz files to get to 100% stock, I'm not saving the files correctly, or I need an older version of TWRP with 10b and 12b?

I'm on 12B and my wife's is 10b and recieving the same error

I downloaded the zip files from Cyanogen's website and copied them via ESexplorer root to the external and internal SD cards

rooted, busybox, TWRP 3.0 (newest on the list)

I followed their install directions but was unsure how to copy the zip file using adb so I just downloaded them to the phone and copied them into folders using root explorer in esexplorer to get the files into hidden folders including TWRP and BACKUPS folders and a couple others just to try (I think this is my issue, how to I copy them to the root SD card) ESexplorer asked for SuperSU rights though)

opened TWRP via the app and manual through the factory reset/yes routes

backed up everything

wipe, factory reset, wipe dalvic/cache and cache again

I tried to install the zip from external and internal SD cards

The errors are

update process ended with error 7: Error installing zip file '/sdcard/cm12.1-rest of file name here.zip"

update process ended with error 7: Error installing zip file 'external_sd/TWRP/"file"

cyanogen mod says to save to /sdcard or adb push to /sdcard/ so it looks like I am in the right folder based on the error's path

I have also saved the zip files in the EXT SD TWRP/BACKUPS folder which conatin my backup from today. They are not in their own folder just files in the BACKUPS folder

UPDATES:

UPdated to 12B using KDZ flash not the .tot, rooted, busybox, TWRP = No change

Manually opened TWRP using the buttons/factory reset/yes and not rebooted from the app = No change

updated SuperSU = No change

100% battery = No change
