[GUIDE] LG G4 F500L - Upgrading to Korean Stock MM without Lg Bridge

[redhatux]

Will help if:
- You converted to model H815 and wants to return to Korean Stock MM.
- Having trouble performing the update by Lg Bridge (Stuck 100%, not recognize device and so forth)
- You flash H815 Stock MM in F500L and get bad signal (I believe!)

** Root access required to change values in BuildProp.
If not root access, I recommend read my another guide to make the conversion to h815, only to have this access.
Remembering that there is still no root access and bootloader unlock after this procedure.​

0) - Download F500L_MM_HOWTO.rar file.
LINK: DOWNLOAD


1) - Install BuildProp Editor and change all values as below.
**This information is extremely necessary for the LGUP software recognizes the KDZ and the device properly, especially those who converted, this information will be the h815. Thus, the LGUP does not find the device correctly.

ro.product.name => p1_lgu_kr
ro.product.model => LG-F500L
ro.product.locale => ko-KR
ro.lge.swversion => F500L20c
ro.lge.factoryversion => LGF500LAT-00-V20c-LGU-KR-OCT-27-2015+0
Shutdown your phone.

2) - Install LGUP. See instrunctons in another topic.
2.1 - Copy "common" folder extracted from zip downloaded and paste in to "C:\Program Files (x86)\LG Electronics\LGUP\model"
2.2 - Rename "LGFLASH_LG_G4_CODEFIRE.dll" file extracted from zip downloaded to "LGUP_8994.dll", replace the existing fle in to folder "C:\Program Files (x86)\LG Electronics\LGUP\model\8994"

3) - Enter Download mode pressing the VOLUP button and connecting the USB cable when off, of course.

4) - Open LGUP and **CHECK!!**
- Phone is connected in STANDBY mode and version is correct "F500L20c"
- Dll Version 0.0.2.13 in footer.


5) - choose "upgrade" option and "F500L20C_00.kdz" extracted from zip downloaded as BIN File. Start.

When ready, an OTA update will be available for V20D version.
Good luck and sorry for my bad English XD​

[benzxi]

so in theory, the F500L will turn into H815, then you can flash H815 roms?

Dear redhatux,
My phone is G4 F500L, i'm flash H81510a and it's not signal.
Now, i'm flash stock F500L20c_00.kdz as above, it's correct.

 

[joseph168]

I did follow exactly the same guide as above but when i connected to LGUP, it showed Unknown model. Please help...

**Edit, its working now** thanks

 

[joseph168]

i got invalid KDZ, how to fix?

i got invalid KDZ, how to fix?

It is necessary that the dll used in LGUP is the "LGUP_LGALL_CN.dll" to be recognized correctly, which can be obtained at this http://get.toygoon.com/20151120/

My phone was f500l. I recieved it as h815v10h rooted. After updating to marshmallow h815v20l only I'm realizing the signal issue. Can i fix signal on h815v20l itself. Or I also have f500lv20u firmware. Can i get build.prop values of ro.lge.factoryversion of f500lv20u.

sorry it's a hardware issue, only motherboard change can fix it permanently but no guaranty new motherboard should have the same problem.

Hi Everyone.

I'm in a big mess.

My LG G4 showed as H815 in device information (But it was F500L) . It had 5.1 (LP).

To update it to 7.0 (N) I flashed the TOT file for N with version H815 thru LG UP.



Now it did complete to 100%. The phone rebooted and showed error like " Central App not loded" or something like this.

I tried again to Flash the TOT file thru LG Up. It went till 21% then shoed error command not recognized.

I triedLG bridge. It shows device as F500L.

Although LG Bridge says update available, it could not update either.

So the problem is I flashed wrong version. My phone is F500L and its showing "firmware update" when plugged into USB with PC.

In LG Up it shows as H81510H

Please guide friends....
