What G4 version/ serial numbers to stay clear of to avoid bootloop? - G4 Q&A, Help & Troubleshooting

So im about to get an LG G4 dual sim variant H818N or H818P and im worried about the hardware defect that most G4s have causing the bootloop. I wont have any way to get it repaired if that happens to mine coz i dont have LG warranty in my country. So any suggestions on what to look for in the fone? or shud i give up on a G4 altogether and get a dual sim G3 (iv been using a single sim G3 for over a year now)?

If you can't get warranty then its best to look at something else. Warranty is your only cover for what requires a motherboard replacement and this is the most expensive component of the device.
Buying new now means you will get a serial that begins with 60x. Older stock would have been sold. But there are reports, a few with that serial also being affected. Course the numbers are very low as more people bought earlier than now but since the price is atttractive there will also be more people interested.
The problem takes like 6-7 months to manifest. Which if you are in warranty gets you a fix at no cost.

If you buy one ,make sure you get with warranty . If not ,think about something else .

Looking for a board and someone to repair it will be big hassle for me so I guess il drop the idea of getting a G4. Thanks for the help.

I guess il go for a G3 then. Thanks for the help.

Bootlooping not sure if caused by me or the hardware fault?

Model H815, bought the device at launch. From UK.
So a couple weeks ago I was messing around with rooting and all that, managed to flash a bad file and ended up in a boot loop. Fixed it using LG Bridge, flashed all the right files and was running a rooted device fine.
Then maybe a week after that whilst just using the phone normally, it freezes, the speakers make a weird buzzing noise and then the phone turns off. Ever since it has been bootlooping. I tried fixing it using LG Bridge again, using the 'Update Error Recovery' option with the device in download mode, it says it was successful but the device still bootloops.
Not sure what to do? Will LG replace the board if it is a hardware fault even though the bootloader is unlocked? I may have also taken the phone apart with the intention of baking it, but never did. Would they be able to tell that I did that and then not repair it?
How much would a repair cost if for some reason it wasn't covered? What's the best way to get it repaired? I got it on contract from O2.
Also, if anyone knows where I can buy a motherboard that would be great, as I'd rather just repair it at home instead of sending it off to LG not knowing if they are going to charge me or not.
Thanks in advance.
It is caused by hardware fail, not by you.
Some people admitted that LG repaired their phone with unlocked bootloader, no luck for me, trying to argue with them.
They'll give you a number to SBE (Their 3rd party repair service), again few people admitted that they repaired their phones for freaking free. No luck for me as well here. They've said "It's unprofitable for them to repair it". I actually think they are retarded, thats a quote of first 2 sentences from their response to me: "hank you for your email. If your handset is still in warranty we would ask that you contact LG customer services for further advice, as we only carryout non warranty repairs on behalf of LG. If your handset is out of warranty by date unfortunately we may be unable to offer a viable repair solution." - WTF is that?
Lastly there is no official place where you can buy a mobo, asked LG about 2 weeks ago - no response...

Anyone here bought a lg g4 from tropical mobile, ebay?

Hi, yesterday i order the LG G4 on ebay from a seller called tropical mobile from singapur, what i wanna know if someone here buy one from them and wich serial number you have 505-509 or higher and if you buy it from him and you have any model between 505-510 did you experienced any problems like sudden death or the constant lg bootloop?
Sorry if my english is bad
go for higher serial number even in s/n 60's there has been reported bootloop issue so ur not safe even in the newer ones buy any other branded phone like samsung dont buy LG but u if got heart for it go for refurbished one those who are already had motherboard replaced n still under warranty by LG cuz even if motherboard is replaced ur phone still could bootloop ...unlocking the bootloader on a repaired G4 is a whole lot different issue also and yes there has been reported bootloop issue is 505-510

[Warranty] Have you ever got LG to repair your phone with an unlocked bootloader?

My phone fell prey to the ILAPO issue where a faulty motherboard causes the phone to bootloop endlessly. I had unlocked my bootloader and was running imperium ROM previously. LG said they'd repair my phone under warranty, but I'm afraid once they get it they'll change their mind once they see that I unlocked my bootloader ("Bootloader Unlocked!" text is still visible while phone bootloops.)
The way I see it, I have two options:
Send it in and pray they only inspect the hardware (they asked me to send it in without a battery, anyways....)
Bake the motherboard in my oven in hopes of destroying any trace of data (but could this temporarily fix my problem by re-seating the connections and cause LG to decide I don't really need a repair?)
What do you think? Have any of you got your phone repaired after unlocking the bootloader?
EDIT: I ended up sending my phone in and it was repaired even though the bootloader was unlocked! Waiting to receive it in the mail
depending on how much warranty time you still have, maybe you could wait a week or 2 and then relock bootloader method will be published, start watching this thread http://forum.xda-developers.com/g4/general/h815-relock-bootloader-t3506634
@OmnipotentPilot : I did and they did.
I had same issue and sent it in and they fixed it and returned it.
I also bought mine 2nd hand so I had no receipt or anything. I went to website and filled out service request, put a date within a year in where it asked purchase date (or something like that), then it says picture of reciept, and didn't provide one. Then i put the IMEI number in and it came back as repair covered...
also for service requested i picked ( i think it was hardware issue or something like that. then "other" so I could type in that it had the "motherboard bootloop issue".
I got a shipping label thru email, sent it in, it was in the facility 12 hrs (they provide a tracking number once recieved), and shipped back out 2day. whole thing took about a week. but I don't think they actually go thru them once it's approved and recieved. Because when you get the shipping label it says what to make sure is in the box when you send it and it specifically says "receipt" but I didn't have one, so it wasn't in there, but everything got done. I think they actually have a bunch of boards and they just put a new one in and flash the IMEI number or something and send it back out. Because my sd card bracket was bent and broken too and that was fixed as well. But I know the glass and frame / bezzel was mine because I had a small scratch that was still there when I got it back.
My Phone had the bootloop issue, It was 10 days out of warranty (just over a year since purchase) and I had unlocked bootloader and Genysis ROM, Sent it in and it looks like they replaced the insides. It's got a new serial number but i still recognised the same little marks on the outside. It came with Lollipop on so had to re unlock bootloader and install genysis again.
Oh and I also dropped the phone in a stream a few months before but got it out within a couple of secs so i don't think it affected it. But they didn't pick up on that either.
Hello,
No problem for me. 10 days and my phone is back with a new motherboard AND new battery (mistake may be for the battery...).
My phone was unlocked with a custom rom.
Have a nice return
Since LG G4 bootloop had gave us trouble last year, now LG realised their mistake.
So LG should repair whether with warranty or not! Root or not , locked or unlocked. They should repair for free
Yep, I bootlooped mine trying to update CM13 when it was in nighly and they replaced it with no problems XD
repaired no problems
i had same issue sent it in with unlocked bootloader and got it back repaired in 9 days
Sorry to bump but I wanted to let everyone know that I ended up sending in my device. I received an email yesterday that repairs are complete and it's on the way back to me! Will edit original post.
No such luck with mine unfortunately, sent it back stating that it was rooted and therefore warranty was invalid.
Depends on the technician I guess. Mine was unlocked, without any OS and it got fixed (over one year to warranty expires). My friend had no luck though. His claim was rejected despite locked bootloader. What is more, the technician claims the phone was water damaged.
In the EU , the SELLER have to change or repair your device for free in warranty time...I live in hungary...my H815 bootlooped...The LG refuse the service...the Official LG repair shop refuse too...Then i research a little....
Read this: https://www.piana.eu/root/
Tomorrow i'll go to the seller (mobile company, Telenor Hungary) and let's the game begin!
Yes. My carrier unlocked/bootloader unlocked/TWRP recoveried H815 that I bought off Swappa was replaced by LG with no issues. They say they replaced my motherboard, but the entire device is new. New EVERYWHERE. I had an H815, now this device has H811 all over it. They couldn't send an H815, so they asked me what I wanted. I opted for the H811 so I can unlock the bootloader (screw AT&T and their restrictions).
New device is already bootloader unlocked, TWRP installed and running stock rooted ROM until the carrier unlock goes through. Then it will be all ResurrectionRemix.

warranty after service applied

Hello , When you send a lg phone for service with issue in motherboard(aka bootloop issue) and they replace it.Service guys associate the new imei and serial number with the old ones ? So if 2 year warranty is over but the new mainboard is much newer, in case of another issue ,for example screen flickering,could we send to it another service center and just don't tell them that the mainboard is replaced?

If im not mistaken it should be from the time they send it back the waranty should basicly be reset. Again if im not mistaken
There have been users send there g4 in multiple times over the last couple years. And ive never heard anyone complain of that.
To make things more clear,
Does service keep record globally to lg the mainboard replacement? So can I claim warranty for screen if passed 2 years from the day I bought it but the replaced mainboard serial number says that I have warranty till August of 2018?Maybe somewhere else from the service shop where I sent it for the bootloop issue because they will not know that mainboard is replaced.
Thanks.

Ill thank that response. That is a very good ? I would like to know that myself.
I was always under the assumption tbat yes any time u send a device in on a waranty and a poce with any kind of serial nums gets replaced the new serial is the new waranty date. I dont think the old imeis are any good any more as people with locked bootloader try to use old unlock bins. Have to update theyre device id and imei with lgs unlock site as their old ones arent reconized any more after mb replacement.

No. Your warranty will not extend to "forever" (if we assume you have a repair once a year.. ) or being reset just because something get replaced. I can speak for Europe only but I don't believe that any other country will do it different. Normally all vendors record the device warranty globally because if not they would loose many money. I say I don't believe but only LG knows for sure.
The bootloop issue is another story. This gets even repaired when outside of warranty e.g. in the USA due to the signed law suit. That's why this is not an issue for the most people.

What to Expect when I get LG Warranty Swapped Board for Bootloop?

Hi,
My ATT H810 LG G4 bootlooped long ago and I was told I was out of luck as the original warranty ran. Since the arbitration forced the warranty to be extended to 30 months in the US, I sent it to LG Fort Worth and they are sending it back with a "Replaced board" for the BS reason "Unit is not charging with cable" (they don't want to document a bootloop problem).
Anyway, I have a few questions while I wait to get it back:
Are they just putting in boards which will eventually bootloop or did they ever implement a hardware fix? Which Serial Numbers are "fixed?"
Relatedly, what I sent in was a 506 serial number. I understand that they may simply reflash the board to that old SN and IMEI and the old sticker will be the same. Is there a way to check what the actual new SN is to see if it's from a "good" batch?
They told me that the 30 month warranty for me was up on March 1, so I just slid under the bar. Is there a new warranty on the repair? If not, is there a stress application to try and force it to bootloop again before March 1? Maybe it's pointless if they're just putting boards into it which are bound to fail...
I know that these points have been covered over the years, but I really can't figure out the current information.
Many thanks in advance!

In terms of your board, if they replaced the board, it will have a new IMEI and serial number (mine did when the replaced it, ironically to fix screen image retention, so afterwards it had to go back again anyway)

If anybody reads this in the future, just a quick note about what they did in the end. They sent it back after "Replaced board" for the BS reason "Unit is not charging with cable". It failed after about 30 minutes of use, would not restart, and would not take a hard reset.
So, I sent it back (the repair has a 90 day warranty). This time, they listed it as "Symptom: Not powering up Repair: Replaced board". So far it's been working fine after this second repair.
Note that the IMEI and S/N (506) stayed the same after both repairs.
