[LG Optimus G (International)] Happy_Alien:
Hi,

I was working on "reincarnation" of F180L (20s) to E975 (actually EUR10h) for the last few days and I didn't find one 100% usable topic.

I had either Korean symbols/language and working signal or my language (CZE, ENG) and no signal - so I decided to have "Czech language with working signal". :)

I got the phone to working state yesterday, after reading about tens of topics and downloading about 7 GB of ROMs/basebands etc. and about 3 days of trying, combining, flashing, drinking a lot ... water only :D etc.

I put many topics into this one and I will hope it will helps to someone else. :p

Phone infomation (original):

F180L with 20s FW

HowTo "reincarnate":

1) Get KDZ file you would like to use - Stock Firmwares:

Link: LG Optimus G [E975] Roms/Kernels/Mods & Tools/Root (Daily Update) or Google ;)

2) Get this package:

Link: F180LtoE975 (FlashTool and Root APK)

I RECOMMEND TO INSTALL THESE FILES/DOING FLASH ON THE COMPUTER WITH WIN XP OR IN WIN XP MODE (UNDER WIN7/8) (I had still PROGRAM NOT RESPONDING in WIN7 64bit - even in compatibility mode)

3) Install all files (3) from "F180LtoE975/KDZ_SW/KDZ Flasher.zip" archive - B2CApp, LGUnitedMobileDriver and MSXML and extract dir "FlashTool.1.0.54"

4) Switch off the phone - connect to USB

5) Turn the mobile on in DOWNLOAD MODE - phone is off and connected to USB - you see battery icon - now HOLD BOTH VOLUME BUTTONS (+/-) and POWER BUTTON (it takes about 3 seconds, then release - I tried to time it well many times, so be patient ;))

6) Look in the DEVICE MANAGER (in XPMode you have to connect the phone through upper bar first) and there should be "LG something" in MODEMS (if you don't see it then there is probably problem with drivers/connection - try to check points 1-5 again)

7) Now you have:

- downloaded your KDZ

- installed drivers and extracted folder "FlashTool"

- connected phone and DOWNLOAD MODE on it's screen

- "LG something" in DEVICE MANAGER-MODEMS

8) WIN7: in "FlashTool" folder set Compatibility Mode for both EXE files to WinXP SP3 first:

WinXP/WinXP Mode: just run as writen below :):

- now run "WindowsEnabler" and click on icon in tray - you have to see ON icon in tray

- next run "UpTestEX" and set flash to (check image "01" for sure):

!DON'T BE RECKLESS AND CHECK YOUR SETTINGS BEFORE CLICKING ANY BUTTON!

----- TYPE: 3GQCT

----- PHONE MODE: CS_EMERGENCY

----- SELECT KDZ FILE: <CHOOSE YOUR KDZ>

----- NORMAL WEB UPGRADE TEST

----- UPGRADE START

- CHOOSE: DIFFERENT COUNTRY and language <WHICH ONE YOU WANT>

9) Wait and pray :):

- phone should restart itself near the end (about 95%) - !IF YOU ARE FLASHING THE PHONE IN WINDOWS XP MODE THEN YOU HAVE TO CONNECT PHONE AGAIN THROUGH THE UPPER BAR IN WINXPM!

- you should se something like "FLASH COMPLETE/SUCCESSFULL" and "FINISH" :)

- it took about 25 minutes to me to complete whole process

- I recommend to do a HARD RESET of the phone after flashing

----- HOLD VOLUME DOWN (-) AND HOME KEY - THEN PRESS AND HOLD POWER BUTTON

----- release the buttons when you see LG logo (or try different timing/holding/releasing power button)

----- with POWER BUTTON confirm (twice) the reset

10) After boot your "reincarnated" F180L to E975 comes the part what took me 97% ot time to successfull "reincarnation" :) - get the signal (now you have iPod :laugh:):

- in the phone enable UNKNOWN SOURCES (in SETTINGS-SECURITY) and USB DEBUGGING (in SETTINGS-DEVELOPER OPTIONS)

- connect the phone to USB - choose MTP and wait for the phone to connect (you should see him in "MY COMPUTER" as a device E975)

- from archive "F180LtoE975" (downloaded at point 2) extact folder "ROOT_OK" and copy "FramaRoot-1.6.1.apk" to SDCARD

- through file manager in the phone run that "FRAMAROOT.APK" file and ROOT your phone - only GANDALF works for me fine

- restart the phone and find and there should be added SUPERUSER in apps (if it's not then install some SuperUser app from Google Play (I am using this one)

- for sure you can install RootChecker

- next install CMW/TWRP- FreeGee works very well

11) Now you should have:

- phone with FW you choose (for example E975 EUR10h - check in SETTINGS-ABOUT PHONE)

- ROOT checked and working

- wrong baseband = no signal

12) Download this file:

Link: F180LtoE975_BB

13) Extract folder "BaseBandF180L_OK" (there was no problem in WIN7 with this procedure) and then:

- connect the phone to USB in MTL MODE and copy "BASEBAND.IMG" to SDCARD ROOT

- check "DEVICE MANAGER-ADB INTERFACE-LG "something"" (it should be OK - only if hou have installed drivers in WinXPMode and you are connecting the phone in WIN7 then you have to install those 3 files from point 2 and 3 above)

- so if you see ADB Interface for LG, you copied the IMG file to SDCARD and your phones ROOT is OK then ...

- just run "FLASH_BASEBAND.BAT" and wait for restart

- now you should be asked for PIN (if you use it :)) and you should get a signal

Phone infomation (reincarnated):

E945 with EUR10h/<YOUR CHOICE> FW with F180L baseband + OK SIGNAL + ROOT + CWM/TWRP

Hope it is works ... thanks to all who made topics which I read a which helped me a lot.
