1. FLASH THE ATTACHED KDZ FILE. Go here for instructions on flashing kdz file. http://xdaforums.com/showthread.php?t=2797190

2. ROOT YOUR DEVICE. Download and copy the prerooted system on your device internal storage. Download LG root and LG Driver from here. http://xdaforums.com/andr...vices-t3049772 and follow steps 7 8 & 9.

Then type "id" and press enter (no quotes).

You should get back some text starting with "uid=(0)root gid=(0)root".

And then this command,

dd if=/data/media/0/system.rooted.H81510c-EU.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0

wait for the # to appear and type LEAVE to reboot your device.

3.RESTORE SIGNAL. As stated by OP. Download backupimg.zip, extract it then copy the folder backupimg on your device internal storage, DON'T RENAME. Install SSHDROID and busybox from play store on your phone and and download PUTTY application and install it on your pc. Try this link. http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Run the sshdroid (you need wifi connection). Run putty on your pc, click on ssh and connect your phone by typing the address shown on sshdroid app and then click load.

What do I have to do?
[G4 General] redhatux:
There's no way. If entered bootloop have to do the KDZ flash again, and so forth...

If the extracted backupimg files are in the phone memory ... maybe to enter download mode you can run all the commands dd by ADB and Send_Command.

Is it possible to convert the H812 into the H815 international model? I don't even use the Canadian frequencies.
[G4 General] redhatux:
Does not work. The baseband of this howto is based on the Korean stock, where there are many peculiarities incompatible with other models.
[G4 General] mehra1:
When I installed the kdz it booted with warning "current version is not available for user. cant find match cust for nt-code mcc.mnc{}, subset{}" and I was not able to use touch screen.

By trying and rebooting several times i got rid of that message i dont know how and then followed all the steps but now my touchscreen stopped working again just after rooting.

Any idea why?
[G4 General] redhatux:
This message is normal after flash any stock ROM.

My advice is that you use a stock rom as base for a CUSTOM ROM, where this message does not appear.
[G4 General] mehra1:
Thanks for the quick reply but the touch is not working
[G4 General] redhatux:
Have you tried flhas the KDZ again?

Great !!!! Now I'm using 7HD v5.1 for H815 V10E. In the first boot, I did't have signal (really bad signal strength) althrough I restarted 2 3 times. I checked and saw "My Model number" is "LG H815" and had a difference between baseband version. I flashed again 2 3 times with these steps. Now my model number is "LGE-F500L". Baseband is base in F500L. Bravo !!!!

Wow, it shows full signal strength. I don't know why but it based in GSM and WCDMA problem. (In 815 model, cannot choose GSM in menu services)

I see that.

Could someone confirm the keys to enter the hard reset in F500L way?

They are different from the model h815.
[G4 General] redhatux:
Discover the keys:

1) VOL Down + Power;

2) Release 2 keys on LG appear;

3) Quickly hold VOL UP + DOWN.

However, in the factory reset screen, the device is not recognized by fastboot. In download mode too, and the QuickBoot app, reboot into recovery mode is in black screen, with the android red triangle and an exclamation. In all cases, the fastboot not recognize. =(

did somebody try flashing marshmellow custom rom from 815 ?

most of threads say you have to have unlocked boot. So I was thinking:

update to 6.0through lg bridge,

make backup or required partitions,

flash marshmallow based custom rom( with flashfire) ( unchecking the kernel, since with locked boot we cant flash kernels)

restore backup partitions from original 6.0 rom.

The question remains if flashfire will work on 6.0 MM or not ?

This method allows changing the bootloader and install an unlocked bootloader to flash a custom recovery?

[G4 General] ezzony:
Hi I followed your instructions and all worked well. As my phone is new I'm playing around with rom's and I updated to MM , stock F500L. I want now to go back and follow your method again to LL 5.1 but this time the flash is failing after phone reboots in Diag mode. Would this be because it's not possible to downgrade from MM?

Another separate question; Has anyone been able to active LTE-A ( band 20 ). It won't activate through the service menu. Unsure if this is hardware or software issue. I only have 3g and no 4g or 4g+. Has anyone in Ireland or UK been able to receive 4g with F500x ?
[G4 General] MitoTakatori:
For downgrading, use LGUP.
[G4 General] ezzony:
I should have mention I tried that already and all I get is KDZ file is invalid ( H815_EU_10C_00.kdz ) . I have used that file once already so it's not corrupt. Perhaps I need to downgrade to F500L 5.1 original first but I can't find it. Anyone know where I can find it?
[G4 General] MitoTakatori:
You can check here: http://devtester.ro/projects/lg-firmwares/country.php?country=Republic+Of+Korea
[G4 General] ezzony:
Thanks , had checked there but no go. Found one Asian site that asks for payment or 'credits' for the rom I want but I don't trust it. I wonder why some are available and some or not or if they will come available in the future. I was wondering is there is some way to edit build.prop without root so I could change the model number of the phone then maybe LGUP or LG Flash Tool would 'think' it's a model that matches the KDZ allowing the Flash to go ahead. Or would it be possible to do it the other way round and edit the KDZ file to match the software version of the phone ? Otherwise I'm stuck with Korean MM. Really wanted to try out 7 HD rom.
[G4 General] ezzony:
I am ready to flash this 7_HD_4.2.1_H815_by_S3V3N-PORT-H811

How did you flash the rom? The roms are not KDZ or TOT format. Did you use flashfire?
[G4 General] ezzony:
Found a stock F500L 5.1 rom here: http://lgviet.com/forum/threads/da-co-file-tot-cho-f500l-f500s.49776/

[G4 General] lavarice00:
Need Help!

Hi everyone. I'm in really need of your help. I have the F500K model, flashed with the F500L tot file which i was able to convert to the H815 model and flashed the Genesysis Rom 2.2.1. Everything went great for 2 months. But right now, my phone is simply dead. :crying:

When powering the device, display lights up but does not show the LG Logo. It's simply a black screen and does not proceed with the bootup. However, I can still enter download mode. Tried using LG Bridge but after reaching around 70% it says

Your phone cannot update.

Click [Cancel] to close or click [Update error recovery] to try again.

I also tried using LGUP and flash all tot/kdz files that could possibly work but LGUP only reaches 4% and prompts: "Invalid TOT/KDZ file". I'm from the Philippines by the way. Can someone help me, please? I would really aprreciate it. :)
[G4 General] mnbb0628:
Can this work for Marshmallow version? I already updated my Lollipop 5.1 F500L to Marshmallow 6.0 and now want to convert to the International 815 version as posted here.

[G4 General] mangintosh:
Hi lavarice00. Did you manage to fix your phone? If yes, could you please guide me through? I have an exact same problem and can't seem to find solution anywhere:(:(
[G4 General] mnbb0628:
Tried this procedure with my F500L that I have just converted back to stock thru LGUP. Now my unit is completely blank—no logo, no nothing. Curiously I hear sound that seems to indicate the unit is running the ROM, except there is no display, I have only blank screen.

What Happened:

Tried to follow all the steps, except that I can't seem to put the unit to proper download mode from the start. I somehow managed to run the download (CSE mode) then the flash tool was terminated by Windows (7, 64-bit) for so-called runtime error, although I have installed the runtime files at the start and the process stated 100% complete.

Also tried to go back to stock F500L thru LGUP, but it's not working anymore. Why is that? I tried looking for a tot file to replace 815kdz, which I discovered is not available.

Anybody have an idea what happened? Any help would be greatly appreciated.
[G4 General] mangintosh:
Try this. xdaforums.com/g4/general/howto-flash-models-tot-file-avoid-tot-t3282938

But rename xVLG to 818 not 815
[G4 General] mnbb0628:
Thanks. That was fast.

I'll try this right away and report back.

Much appreciated.
[G4 General] mnbb0628:
What I did: changed the string "F500L" with "H815C" once at the same exact location shown by the image at the link, saved, and tried the LGUP using the new revised tot file. Didn't work.

Was I supposed to change every instance of "F500L" or something else?

TIA.
[G4 General] mangintosh:
Replace "F500L" with "H818" not "H815C" only once.
[G4 General] mnbb0628:
I'm sorry, but wouldn't "H818" have trouble with the current nonworking ROM in my handset, which is H815C? LGUP registers it as such, "H815".....

Also, I have no WinHex, so I tried another hex editing program. Would this matter? I'm thinking of getting a working WinHex today.

Thanks!
[G4 General] mangintosh:
I'm not sure about using another hex editing program but I dont think its a problem. I also had H815 rom and LGUP registered it as H815 as well. I tried to replace "F500L" with "H815" in the tot file but LGUP couldn't flash it, gave the invalid tot file error. But when i replaced "F500L" with "H818" it worked. Can't really explained what happened but trust me it works.
[G4 General] mnbb0628:
Wow, as simple as that? Will try this again later today. Thanks a mountain, man! Hope this works! If it does I'll try my hand again at flashing that H815 after I reformatted my PC, which has been a pain in the **&%$ lately with all things android. At least I have this to fall back to if that fails again. :)
[G4 General] mangintosh:
I wouldn't advise on flashing H815. If it fails PM me.
[G4 General] mnbb0628:
Will do. After office today.

Is it no longer advisable to flash H815? It's just that my unit still suffers from occasional bootloop using the stockrom and I want to be done with those Korean apps.

Again, thank you very much!
[G4 General] mnbb0628:
Update: I tried it again last night, still no go. But: I didn't mention that the MTP is not properly installed in my PC—does that matter? I was thinking it was all USB connection, and since that was properly installed, the MTP is of no concern. Am I wrong assuming that?
[G4 General] mangintosh:
MTP is not really important. What we need it is to be able to get in download mode. Did you put it in download mode and tried flashing using LGUP? Did you use winhex to replace F500L with H818? What error message(s) are you getting?
[G4 General] mnbb0628:
Okay at least this confirms my belief that MTP should not matter, esp. since the phone is dead anyway for the connection selection to be available.

I used both LGUP first and this Flashtool 1.8 xxx that uses tot files. Both failed. LGUP gives the same "Invalid tot file error" message, while Flashtool merely indicates in red (at third step) something like Download Failure.

I tried using WinHex but it gives a weird error message when saving, so I went back to that other hex editor (will give more detail at home, can't remember the specifics right now).

Tried the kdz flasher one last time before calling it a night, using a stock kdz I've gotten hold of, still no luck.

I am thinking of reformatting my PC today or my laptop to see if my quirky old installations are the culprits. :)
