Lg G4 F500L - Fixing and Converting to International H815 Model

[redhatux]

TESTED ONLY F500L WITH LISTED BELOW SOFTWARE VERSION
Fixes BootLoop , restore 3G/4G Carrier Signals , removes bloatwares and sms limit
I have good news. Latest software also work.
I think that works in all versions software. So long as we do not have the KDZ for the Korean version.
V10E / V10G with Root Working great!
Genesis 1.2 ROM Working great!
7 HD 4.2 ROM Working great!
​

HELPFULLY DOWNLOADS LINKS TO KDZ AND ROOT (Will not help with that)

KDZ
http://downloads.codefi.re/autoprime/LG/LG_G4/H815/H81510C/H815_EU_10C_00.kdz

PRE-ROOTED SYSTEM IMG
http://downloads.codefi.re/thecubed/lg_g4/lef/h81510c-eu.tar.gz

backupimg.zip (All partition images necessary)
http://drive.google.com/file/d/0ByvysDj-CgQWbDcwTlBzVld1d3M/view?usp=sharing


REQUIREMENTS
Flashed H81510C-EU KDZ with root access.
Install BusyBox and SSHDroid on PlayStore.

Procedures
Download and extract backupimg.zip. Send folder "backupimg" to G4 internal memory.
Start SSHDROID service on phone and connect it with ssh - Putty(win) or Terminal/Shell ssh command.

Already connected on phone, in terminal, access copied folder:

cd /storage/emulated/0/backupimg/

List all partition .img files

[email protected]:/storage/emulated/0/backupimg # ls
aboot.img hyp.img persist.img raw_resourcesbak.img rpmbak.img sdibak.img
abootbak.img hypbak.img pmic.img rct.img sbl1.img sec.img
boot.img laf.img pmicbak.img recovery.img sbl1bak.img tz.img
factory.img modem.img raw_resources.img rpm.img sdi.img tzbak.img

List all partitions: (showing only 2 samples )

[email protected]:/storage/emulated/0/backupimg # ls -al /dev/block/platform/f9824900.sdhci/by-name/
lrwxrwxrwx 1 root root 20 Jan 12 2015 aboot -> /dev/block/mmcblk0p8
lrwxrwxrwx 1 root root 21 Jan 12 2015 abootbak -> /dev/block/mmcblk0p14

Use #dd command to dump image file with respective file => partition, for sample:

|[email protected]:/storage/emulated/0/backupimg # dd if=aboot.img of=/dev/block/mmcblk0p8
4096+0 records in
4096+0 records out
2097152 bytes (2.0MB) copied, 0.167950 seconds, 11.9MB/s

[email protected]:/storage/emulated/0/backupimg # dd if=abootbak.img of=/dev/block/mmcblk0p14
4096+0 records in
4096+0 records out
2097152 bytes (2.0MB) copied, 0.166665 seconds, 12.0MB/s

Do this for all 24 files corresponding to 24 partitions listed (see the name of each on /dev/block)
After, restart 2 times the phone.
The first time you start the phone, do not even get signal. The second time, the signal will return.:laugh::laugh:

Ok
Now it's clear. Which app I should use to send these commands

Ok

Just by closing the download tool, I decided to do some tests.

I tried to use the ADB and the FlashFire APK (No Success - not permited to dump partition SBL1, sec, factory and aboot) in both options.

To work, install and open the app SSHDROID (Your G4 is an ssh server now)
He will show you the IP address to connect directly via ssh:
user: root
pass: admin
Once connected, run the above commands.

 

[Power_Getter]

Worked !
thanks

 

[redhatux]

Worked !
thanks

I will carry out the tests with custom roms and other latest software versions.
Any news, notice.

 

[love_rain_2303]

Great !!!! Big thanks for you !!!!!! It's work

Ok, Been using the phone for almost 12 hours now and I notice one thing is not normal.
I have fair H+ signal at my work and I have my other phone to do a comparison.
* HTC M9 = Stable H+ signal between 3 to 4 bars
* LG G4 = same as HTC, BUT when wake up the screen from a sleep for at least 5 to 10 mins the signal is not stable which shows H+ 4 or full bars then goes to 1 bar only for few seconds after that back to normal. My other phone not doing that, Any idea?

No found problems to wake up the phone after sleep.
Always has full bar + 4G signal where I live. But I believe that is not a big problem for those who were with the dead cell right?

In time, I have good news. Latest software also work.
V10E / V10G with Root Working great!
Genesis 1.2 ROM Working great!
7 HD 4.2 ROM Working great!

 

[Power_Getter]

Yes. I'm running 10e rooted
After few reboot it seems get better
Almost perfect.
Thanks for your great effort.

You have to do it all again.
1) Flash 10H KDZ for Genesis or 10E KDZ is 7 HD ROM
2) Inject root
3) Flash ROM or Genesis 7HD ROM with FlashFire APK (easier)
4) Follow all the steps to return the carrier signal

Personally, I'm with 7HD ROM. Much better, with Xposed, modules, G4TweakBox, Busybox, UI improvements, battery performance and so on and so forth...

 

[fazzula]

excuse me a little question. following this procedure an F550L will become a H815 in every aspect?
I'm particularly interested in radio FM presence and its correct functionality
second, is it still possible to activate/deactivate LTE bands after this procedure?
can you check please?

thanks

FM radio does not work, although you can install app on update central and use it. To tune the stations, but is muted.
I think the Korean version does not have the hardware to FM.
Yes. Select the networks can do. Works.

 

[lequocvan]

@redhatux can you try Factory reset? Do you loop logo?
I wait for info from you.

 

[redhatux]

Someone could test the NFC ?
NFC is not working here... =(

NOT tested.

Hi there I have a f500k. Do you think this method will work on my device also? I don't want to take chances as the Korean versions don't have kdz and may I know if the signal will work after the change as I live in India.
