G4 Motherboard Replacement. Need help picking the right one? - G4 Q&A, Help & Troubleshooting

Classic G4 bootloop. I offered to fix this phone for a family member not knowing how much of a head ache I'd be in right now 12 hours after I started.
Anyways, I've tried pretty much everything. I'm just going to get a new motherboard and replace it. But I've never replaced a motherboard on a phone before. Is there anything specific I need to match up with the new board?
The G4 I'm working on is a H810 (AT&****) model. The firmware is Marshmallow 6.0. Any other info you need, just let me know.
Appreciate the help!

If serial number starts with 5 manufactured 2015 as it is first motherboards affected by bootloop
6 2016 they started correcting issue
7 2017 are harder to find, but last make of motherboard
5 will bootloop for sure
No problem

Pm seller before purchasing
Better to take ur time when making purchase like this
Try Amazon as well
I personally don't like buying off eBay because off all the products that come from China....and they take up to 2/months to receive

Why does Samsung wipe your device for a screen repair?

I sent my t800 in for a screen repair had it exactly how I liked rooted, blisspop on backup and currently trying out ironman. All my settings, games, icons everything possible gone. Its back to nib. I'm relieved my device is like new but what's the point of them doing this? Plus I don't have a windows PC so getting root is a hassle. Sorry just annoyed

Well probably to be extra safe of making sure everything works. They mostly do that with every repair they do

They could at least mention it when your setting up the repairs. Plus the tablet had rapid battery draw before and it still has it. There supposed to do a full diagnostics after repair

Maybe they didn't send you your repaired device, but a refurbished one. This is quite common with electronics. Did you check serial/IMIE numbers?
I would asume that, too.
they always wipe for data protection ****

I did send in my gs3 when it came out for repair, because the screen broke, and I asked the customer service people why they wiped the data, they gave me various reasons like ; I might get a refurbished one, they need to make sure the screen works and they run various tests. And for my own privacy protection so that no one intends to go thru my phone and gather data.

LG G3 build # JDQ39B

Hello all,
just a quick question as I'm new to this phone and have a few starting questions(I'm coming from HTC one so this is all new), I have read and read threads about build numbers but I'm not finding mine. I have the d855 variant with a build #JDQ39B and it has 4.4.2 but it is horrible. it's missing alot of features:
edit options oe Q-Slide within the quick settings
Dual screen
multi copy and paste
and many other factory features.
Also the battery life is horrendous( recharge it 3 times per day).
What I'm looking to do is either change the kdz firmware file to another region( preferably canada if possible) or root, install twrp and install a ROM such as Cloudy G3 2.1( again if possible).
But because of this starting issue of this phantom build # I don't know where to begin. Any help would be appreciated. Thank you.
Also, apparently this device isn't compatible will stumproot. which sucks but I'll try towelroot as well.
update, towelroot will only give me a text file no apk. again, that sucks.

Brother your LG G3 is a fake
Sorry
I was hoping this wasn't the case. I can't believe I shelled out $380 for this.

Remember, if its too good to be true it probably is
LG G3 is still roughly mid $450s (if your lucky) to $500 something in most stores
Noone would sell one for $380 unless its a LG G3 Beat or if its a second hand phone
Its fake who'd you get it from?
Just never seen any fakes yet? theres the Kings something but that doesn't even hold the same shape. I've stripped this thing down to the motherboard and it all jives. Amazing work they did. I'm gonna try a oem battery and see if it helps longevity?

Is G4 still bootlooping on manufactured versions of 2016?

Im planning to buy this smartphone by the end of January 2017, its the European version I think (Spain)... But Im afraid it would still bootloop as older G4 devices manufactured in previous months, so...
This problem has been fixed in newer devices?
I was thinking in buying the G5 but the price I have found for this smartphone is quite interesting.
Greetings, and happy new year
Hi ! I don't know at all.....but mine is a h815 sn 506 bought on the begining of November 2015 ....and never have had problem ! Work like a charm ....

How many times is this gonna be asked? No one can tell you if it is fixed with "newer" G4 devices. Anyone who owns this device should have a backup device because you can't trust any G4... and even if its fixed, I still do not recommend this phone. It has many other problems which is in my opinion not worth to deal with. I regret buying this phone.
See my reddit post ---> https://www.reddit.com/r/lgg4/comments/5glnlt/bad_quality/?ref=share&ref_source=link
If you really want to go with LG, buy the G5, that phone isn't flawless but much more reliable than a ''newer" LG G4.

Oh it didn't really bother me, I was more like: Another one wondering if newer versions of the LG G4 are bootloop free...
Well simply no one can tell you for sure, there are some reports of newer versions boot-looping, but that are only a few but still some..
If I was you I wouldn't go for a LG G4. Take the G5 instead if you really wan't a LG phone. That phone has less problems and has better hardware and will be more worth your money in my opinion.

its a risk you are going to take.. but if your want to decide , then yes we cant tell you but, indeed 6XX have low chances of bootlooping but it doesnt mean it wont..
someone said that he opened old opne and when he received the 6XX the internal had better quality and previous had not.

Yes I know, I never said that there aren't G5's with bootloop problems but with that device it is way less common.
And that why I think he should better go for the G5 if he really wants a LG phone.
It's a worry though - if they can bring out a new gen device that still has the flaws it took them a 35000 strong petition to even acknowledge... not a trustworthy company.
I'm sorry to hear ppls had problems with their G4 phones .
What I can say , speaking from a developer perspective , LG g4 is great , at least the one I have , I have a h815 European Unlocked , serial number starts with 6xx.
I just can tell you that i stressed this phone like no other phone before .
I always think how this little piece can take so much stress.
I'm a rom developer and I can say I i flashed and reflashed over 10 -15 times per day different roms.
I build Maru OS for this phone and I runned Debian inside it ,with a lot of app oopened and a lot of multimedia tasks , and tested a lot how apps works on it , even games.
I used it like a pc , using debian and I can tell you I stressed it a loooot .
What I can say is that is a good harware , I do not try to convice anyone to buy one and I do not want ppls to spend money on something that can easly brick . But told you , I was impressed how mine resists to stress. No problems in 4 months.
Have a great day all !
Mine is 602 and it's still going strong. No issues. No overheating. It's works flawlessly.

I currently have the mate 20 pro and it has the green screen issue. So... Sadly I'm sending it back, I was going to swap it for another though amazon advised me not to. They also refunded the accessories I purchased which supprised me. I now don't know whether to try to import a mate 20 X or settle for the 6t. I would be grateful if anyone with the 20x could help me decide and answer a few questions?
I haven't seen any threads about it. But has anyone had any issues with the screen?
I've read some people have had problems with the Chinese version, when looking at adverts how do I make sure the phone I'm buying is the international version? Most don't say they just give the model number.
Is there an 8gb/256 version of the international model? Does enyone have an ebay link for where I could get it sent to the UK?
Does anyone have any reasons why I shouldn't consider getting this phone?
Thanks for your help.
I don't have the phone (at least yet) but i'm following closely all threads because i'm very interested too and i never see anyone complaining about the gluegate, even a reviewer frankytech thinks its only targeting pro series because of the curved screen.
If you want to buy international version you need to check if the model is named EVR-L29, china model is AL00. There's no international model atm in 256/8GB variant. About sellers to the international, there's splendor, wonda, funkyhuawei, expansys and ebay. Probably more but i forgot.

Is it easy to add the play store? Are there any issues with Google services? e.g. Google pay? As I use that a lot.
I bought an xaomi tablet and that took a lot of effort to get Google app store and services working properly.
Also I was wondering does face unlock work OK on this phone? I know it doesn't have the 3d scanner.

I came from a OnePlus 6. Definitely get the 20 X if you like large screen phones. The X uses a Samsung AMOLED panel and is free of defects. I would buy the Global version if root isn't important to you. If it is then buy the Chinese version. I bought the Global version and have no issues with it. The 6gb/128 Global version is plenty fast. You won't see any difference between the 6gb and 8gb versions as far as speed or apps in memory goes, it's all pretty much a gimmick unless you're buying the 256gb/8gb version just for the storage size.

The storage was the main reason I ended up going for the Chinese version.
I'm worried about Google pay not working on Chinese phones but I'm hoping the rest will end up working OK.
Hopefully someone will work out how to rebrand it so I can have the best of both worlds.

I have the China 8/256 version. And although I was worried about getting it once I changed the language, keyboard, got Google play to work it's a great phone.. my wife is laughing at me saying it's too big but personally I love it. It's fast and smooth and the screen is amazing.
I've not tried Google pay yet. I was able to add my credit card but not my bank card strangely. I will try Google pay tomorrow and let you know.

Where to buy real LG G4 (H815) motherboards?

All the motherboards on Aliexpress are fake - run @steadfasterX's SALT and it shows they've all been modified in some way, with crazy ARBs of 20 and even 40!
Where (or which seller) would you guys recommend getting legit motherboards, and not frankenboards?
The phone was released in 2015, I don't think LG still makes motherboards for this phone.

I haven't checked recently but there is/ was an Israel- based seller on ebay selling H815 boards. I bought two a couple years back, about $50 apiece, the default language is Hebrew but of course a different one can be selected during setup... Still amusing that the phone dialer shows Hebrew numbering. AFAIK they are real, never had any problems.

Hi guys, I seem to have a franken h815 too. I wanted to find out the actual model by checking the motherboard.
All that I see is a little qr code with one number underneath: RS1017 (or BS1017) and one number on the side: 066C15. I could not find out which model corresponds to that, could you help me?
Edit: Found it out already, the model is written on the backside of the motherboard
