LG G4 motherboard swap - G4 Q&A, Help & Troubleshooting

Hi guys,
Wanted to ask if it is possible to swap the model of the motherboard on LG G4.
I have a broken H815 (bootloop) but the housing and display are OK.
I want to get a mother board from Korean Model F500L S K. Are they the same dimensions and does korean mainboard fit on my housing and connect to camera display etc?
And are the korean models affected by the boot loop since I'm no seeing any of them on the internet.

Yes, the motherboards have the same dimensions. It will work

Korean version probably not as popular
Get h815 again

Korean version has similar mobo as the H815, but as mentioned above, its not that that's why you dont see them bootlooped. Only advantage of the F500 is the new 7.0 FW.

Bootloop is a known problem of the LG G4.
The cause is a loose contact on the PCB.
LG offers a free repair.
Owners of a LG G4 affected by the bootloop are requested by the company to contact their mobile operator to initiate the repair process.
Customers who have purchased the G4 in free trade are kindly requested to contact LG support directly.
The repair takes place within the framework of the guarantee conditions and is therefore not associated with costs for the owner.
In addition, the company apologizes for the inconvenience that the previous solutions have brought to customers.
Previous misdiagnosis resulted in the replacement of wrong parts of the smartphone.

Nah, I'm not interested on the os version.
I just was wondering if F500's have less bootloop issues.

Well Thank YOU very much for the answer, I'm very aware why the bootloop problem was occurring and know the whole history of the problem.
But I live in Kosovo and we don't have an official lg retail store.
I contacted LG Serbia and explained them my situation. But they were willing to help just the cases when phones where bought in Serbia, so nothing for me :crying:
Since you provided some information about "free trade" phones. Is there still a chance for me to get a fix for my phone. Since when it bootlooped it was only 8 months old. So well under the "1 year warranty policy".
Thank You Very much again.

The F500 which is the Korean version I think has LTE bands/frequencies missing or disabled which makes it a no go for use in western europe at least. It might be okay on some networks depending on what frequencies your network provider uses but in general I'm sure the F500 is the most limited version when it comes to working frequencies so it would be much better to get H815 or H811. The F500 mobo is exactly the same shape as other models btw.

Your welcome. My first G4 was a F500 and I found that 2g didn't work in bad signal areas so I couldn't even make a phone call. Also 4G+ didn't work either. It was possible to put H815 firmware on it but that did NOT enable the missing frequencies so I had to buy a new one.

Yeah a phone with no 2G and 4G is probably useless.
But now I wonder if H811 European models, suffer less from bootloop, because if I decide to buy a new mother board the last thing I want to happen is my phone dying again.
I talked to a mobile phone shop owner here and he told me that they just returned many G4 since they still bootlooping (after only 1 month of use). And they won't sell them anymore.

I bought a refurbished G4 for 170 euro. It has a s/n of 701, in other works very recently manufactured....I have it working fine for 5 months now with no issues at all. So I would only buy one with serial 609 upwards. It's not know for certain which one is okay but the more recent the better. It does not matter at all whether is F500/H815/H811/etc where bootloop issue is concerned.

Thank you so much for the advice.
Yesterday I found a G4 H811 in a mobile shop here. But it was S/N 401 so a big NO NO for that
I will be thinking of buying a brand new mother board from china and replace it myself and it is half the price of a new phone.

I asked the China supplier what was the serial number and he woulnt tell me. Thls means that althought the board is new and unused it may still be an old one with bootloop issue down the line.
The best thing to do is make sure s/n is 701 up. You can ask eBay seller what is s/n by email before buying if buying used one. They will be happy to tell you. That what I did and enjoying fone since!

The LCD is version-independent, so you should be fine

Hi, will a LG G4 Stylus mainboard fit inside a "normal" Lg G4 case? I have a working LG G4 Stylus mainboard and a friend has a LG G4 with damaged mainboard.
Thanks in advance

Confirmed sellers with H815 (Euro model) on eBay?

Does anyone know about confirmed sellers that are selling European model of LG G4 on eBay (shipped from USA)? I've contacted a few and it seems like almost everyone is selling the Asian version (H815T).
Never-MSRP told me the same thing so I think that they do have Euro version. The only issue is that they I'm in Houston as well so they charge tax so that's why I haven't bought from them.

Anybody ever make any progress on finding a good source for the EUR models?
Only those can be BL unlocked (ATM anyway) right?

Fast, cheap and painless.
There are tons of threads about this exact topic going back to release day, all point to this site.
I and many others purchased from - http://www.ebay.co.uk/usr/tfawes26?_trksid=p2060353.m2749.l2754
Even the black leather one he sells (which is incorrectly listed as a H815T in the specification section) is in-fact the EU H815 model.
The seller is a little slow at posting and quite poor at replying to messages but he is completely legit.

Thanks, doesn't look like he actually has any available for sale at the moment though?
Man I wish LG wasn't such a B about the bootloader situation. Why can't all the 815's be open... Arrgggggg

I also bought one from this company and it was indeed fast cheap and painless, received the phone the very next day. It was an H815 unlocked and I have the unlock.bin, which I received from LGE with no problems, file saved for future use. The phone is now updated with the 10c kdz file and rooted by the method described in another thread in this forum, which was also easy to follow and painless.
I have an CZE H815 but today just freezes, I turned off and never turned on again, I never had falls the phone to the floor, just take care the phone like jewel and now never turns on again, the phone has in warranty yet but only in Czech Republic, don't know if someone want a cheap phone to use in warranty due LG doesn't offer international warranty.

bought a G4

hello guys. i just bought a G4. i plan to root it in a few days. i have heard alot about the g4 having a motherboard issue? is this true? i spent all my hard earned money on this so it can last me atleast a couple of years. how commmon is this? my phone is an international version with the code 506.
How common is this? Even h815t hong kong is having same issues on xda, i am worried if this is wide spread or few people, or specific behavior ?

As long as its come with warranty in your country they will fix it. If not, you decide yourself. I never have a phone that just died on me before like 7 months. My G4 believed to be the first batch 505. So no warranty for me.Because its given by LG before it selling.

yes...
it seem that the series concerned are 505 to 509 (june to september 2015) but i'm not sure ,need to be REALLY confirmed at 100 % !
but it sure at 100 % that 505 are concerned !
mine is 506 too but with the story of loose of warranty in case of bootloader unlocked ,i'm not fan at all to do this unlock...

if you mean all variants i think so am not sure on dual sims..
according to LG problem was fixed since october 2016. but even new phone still get bootloop. the latest ive remeber was a april-16
well its not 100% guarantee but ask for first 3 digits of serial number. and try getting newer.. or at least from 601
that meas 601 means 6 its year 2016 and 01 month january. so a 510 will be 2015 october. from 601 up. the better.
try getting a phone from your country, if you get a phone from other country you must send it there not your country. so as long as it has warranty send it and will be fixed.
My LG G4 (Verizon VS986) has been good to me. It came on MM but i ran the downgrade and went to stock 13b and then 13b rooted, and its been great. Never a single boot-loop, no problems at all. I do suggest, If you have the option to get a NON-Verizon variant, preferably one with an unlocked boot loader, I suggest going to that variant of G4. Unless you don't care about rooting, or any ROM's, then Verizon will do just fine!
don't buy a G4... they have extremely ****ty customer service, they lie a lot and the phone itself has tons of issue
Focus on any other brand except HTC

LG G4 H815 - Bootloop help

I have the H815 and I'm in the USA. I'm not the one that originally purchased the phone from LG, I bought it from someone on Swappa almost a year ago.
Is there any way I can ship the phone to LG outside the US? Would that even work? Should I try taking it to a phone repair shop?
I really want to keep this phone model.

contact the phone country LG and ask them.

Is H815P different to the other models of H815?

Hi everyone,
The screen on my H815P broke. On eBay replacement screens are listed as being for the H815. Will these work? A shop in Luxembourg refused to repair my phone because of the extra "P" in my model number, which I understand means its a model sold in Latam and South Africa (strange because I bought the phone on Amazon.de).
Also, is there a way of knowing if the screen I buy really is a genuine LG screen?
Any help is really appreciated.
I think the main difference is the modem. I'm 99.99% sure that all G4 editions have the same (awesome battery hungry) screen. Also, the only way you can be certain you bought a genuine LG screen is by buying the screen from LG.
Hi. The main difference is the motherboard. H815 (no letter) can be bootloader unlocked and H815P doens´t. The rest is all the same. In case of the screen. I was replace the board from my H815P to H815 (same screen and battery) and works normally and fine.
In order to know if the screen is or not genuine, depends from shoper and rating by customers and other -buy&sell pages- matters.
If you purchase a screen, replace it without warry becausae it will work.

Cheers. I've gone through to the LG spare parts website, which belongs to an outside company and it requires the model number for the screen. How the heck am I supposed to know that?
Anyone know a link to a genuine screen that delivers in Europe? I've been checking out youtube videos and I might attempt this repair myself.

Thanks. If you know of a European supplier, please advise. I tried contacting a supposedly official LG parts supplier out of Portugal that was recommended on one of the threads here on xda but they haven't responded.
