LG G3 build # JDQ39B - G3 Q&A, Help & Troubleshooting

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?

Why so few roms for H815?

I was considering getting an H815 for use on AT&T instead of the new Moto. It appears that you can easily unlock the bootloader. It currently costs less than $450 on Amazon for a 32G leather version. It has an SD card, replaceable battery, great camera, and a good SOC (that does not have issues like the 810). So, why are there so few roms for it? I won't buy a phone unless it is first well-supported on XDA.

H815 will not work with VZ. You have to buy the VZ variant so no unlocked bootloader but can be rooted.

I also do not understand what this means. Are you saying that only OPEN EUR versions can unlock the bootloader and flash roms, and that so few people own them that no one has bothered to create a custom rom for the phone?

Almost all European h815 can get unlocked. H815 without European imei wont work.

As for ROMs, I have been noticing that for a few years on a lot of phones. If you want ROM's, you really need to stock with Nexus devices these days.
I have bought a G4 and luckily mine could be rooted. But yes, there are very few roms available and as a former Samsung user I must say I'm very disappointed with the help you get on the forums. Most queries aren't answered. If I were you I'd stick to HTC.
@phoneturf the h811 is the most prevalent version. I wouldnt get the 815.

Here it is a month later and the support for none of the G4 variants appears to have changed. There are a couple of stock roms for the T-mobile version, but doing a little reading I cannot even tell if there's a working TWRP or CWM for it. I decided to check back with the G4 since now I am instead considering a V10, although I suppose now I won't really consider that one either - I really wanted a replaceable battery and SD card.. If they sold one with an unlockable bootloader for all carriers, like Nexus, Moto, or OnePlus, I assume there would be much more support.
I bought a used G4 815 on Ebay, before I know that only the EU version could be opened (will see what's arriving in a day or two )
Is there any work being done on an Unofficial bootloader unlock?
I saw that the G3 does have allot of roms, did that phone was in the same situation as the G4 at it's beginning?

The G3 was originally in the same boat as the G4 as well in the beginning. That's why everyone is saying stfu and wait. A lot of folks just look at Nexus and other easy unlocks then expect everything to come into their laps within seconds.
And there is an unofficial bootloader unlock in the works. BUT it appears it only works if you haven't taken an OTA update before. All in good time my friend.

I am looking at the Blackberry Priv over the v10.
Take a look, it may do what you need it to and have some extra features added in as a bonus.
Only problem is I do not know what the dev community will be like for this phone.

Well it came in, it's H81510b-TWN-XX :crying:
In the hidden menu I don't see any "roolback" value, so does this says something?
Does using the "low effort root" / installing 11a or 12a will make the roolback value go to 1/2?

Thanks for sharing!

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 ....
(v20i MM + Llama kernel....and sometimes simpleGX )

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.

G4 Motherboard Replacement. Need help picking the right one?

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

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

LG v35 ATT Engineering Sample with unlocked bootloader on eBay (LM-V350AWM- SLV)

So I was digging around looking for a unlocked LG v35 on ebay and came across this ES version with Magisk already on it, and in one of the pics it shows it running 11i firmware if that helps. basically proving that it has full root access I just thought this may prove usefull for us trying to gain root to this great smart phone. i don't have the money to get this specific phone yet but, maybe one of you guys out there does. I'll post a link to the phone itself down below. There are some pics in the sellers post showing that the phone does have Magisk running on it. I'm msging him about where the phone came from and how exactly the phone ended up in his hands. Maybe some of you can reach out to him to. I don't know about you guys but, this seems like some of the best news yet on the LG v35. Being able to actually purchase this phone, i thought would help.

Which G7 Variant is best for Root + Tmobile/Metro??

I know i know the G710TM cant be bootloader unlocked, but i can take one of the other variants thats GSM unlocked and bring it to Tmob, so which one is best for compatibility? Specifically looking for 4G LTE and mobile Hotspot to be working correctly. Is this possible, or should i stick with H932 (V30) and root that instead?
thanks in advance
idk but LMG710TM definitely can't root

not looking to root TM, I know this already.
I decided to get ULM and get a remote unlock. I dont see as much development with the G7 as I did with the V30 which is sad.

You are right the deveploment for the lg g7 here on xda is pretty much dead.
You can also get a sprint variant really cheap on ebay
Thats what i did now is rooted on pie ulm but theres nothing else to do since the deveploment is dead.

Gah. you just sealed it. I'm glad that I didn't make the purchase as of yet. But my suspicions it looks like I was correct. I was debating either upgrading all the way to v40 but it looks like development hasn't gone very far either. though I would like the five camera setup and the portrait mode of the two front facing cameras I don't know if it is worth it as having root plus access custom roms is what I'm really looking for. It looks like development for the v30 is where I need to be. Plus I have all the tools necessary to root it. I've actually rooted it before but the phone was stolen for me
Can it really be that a two-year-old smartphone is really the best bet? I can buy 2 v30s for the price of one v40
