Find G4 serial # via software? - G4 Q&A, Help & Troubleshooting

I've looked around and can't seem to find a way to determine a G4's S/N outside of looking at the physical device sticker or the box it came in.
Unlike many devices it doesn't show up in Android phone status, nor in any of the "secret" service menus I know of.
Is there a tool that can do this? Thanks.

I know there was a lg site u could check waranty it gave manifacture date. Which u could kinda tell the serial then from comparing to other dates

Thanks.
The only thing I worry about with apps like this and the various IMEI websites out there is that they might be collecting IMEIs to do something like try to clone the phones or something.
Am I being overly paranoid?

I may have seen that before.
I would be less worried using something like that if it were run by LG itself, rather than a 3rd-party site where I don't know what kind of funny stuff they might be doing with collected S/N's.

[Q] Which IMEI should I use?

I searched but could not find my specific question referenced anywhere. I just received an unlock code from T-Mobile and it is, of course, tied to the IMEI of my TP2. However, when I look up the IMEI code on the phone, or use *#06# as T-Mobile suggests, it returns two additional characters (total of 17) that does not exist when I look on the back of the phone under the battery (total of 15). I don’t know which number to use and wanted to ask the advice of anyone here who might know since we are only given so many attempts before it locks up permanently (according to T-Mobile). I am using a custom ROM but based upon the searches I’ve done, that should have any impact on either the IMEI number or unlocking it.
Thank you in advance for your help/suggestions/comments.
I would use the one on the sticker under the battery, especially if it matches what tmo gave you.

np, sometimes you need a push .
Out of curiosity, anyone knows why the IMEI numbers are different?
the IMEI numbers should match for the FIRST 15 the extra 2 digits are more or less "add-ons" that are board specific??, if the numbers do not match at all it means the case has been replaced and then you should use the FIRST 15 numbers you got from the phone (board)........hope this helps???

[q] a question about the imei code

Hi guys, I got a GN lately from HK,but I have a question about my phone,the IMEI code,I wonder is there any way to check my IMEI code whether it's been changed or coverd by tools. I tryed the code:*2767*3855#,but it dosen't work.
Thanks!

I think it should be under the battery.
Its printed on a sticker under the battery door. And its found in: Settings > About phone > Status > IMEI

Yes, there is an IMEI code under the battery, and normaly, you can check it by type "*#06# on your phone, but, as what I know, the tip about IMEI under the battery can be faked!
And ,once your IMEI code has been changed or faked,you can never find out the true info.about where and when your phone been factured.

If the sticker has been changed, and they've somehow changed it in software (under about phone) then they've surely changed it any way that you can check by dialing a code into the dialer app... Check the sticker and compare it to the software and that's about how much you should worry about this.
Don't be so paranoid.
You must have bought it on Craigslist or worse like the black market or something!? Humor me and tell me what it is you are worried about? Like a drug dealer or a terrorist has your real imei code and your going to get indefinitely detained or something? I honestly don't understand.

[Q] Repair/Restore IMEI

Hi, I had a problem with my Note 2 and I brought it to a UK Samsung repair centre, they did something to it and now my IMEI reads 0049990106400001 (which is different from what the sticker on the pack of the phone says).
The issue is that Samsung won't touch my phone now because it's not a UK phone (I think they did not realise that the first time round).
Anyway, don't get me started on this... after searching the net for days it seems I have to restore my IMEI. I tried a few methods, but unsuccessfully.
I was wondering if anyone has suggestions on what I should do, or maybe the name of a reliable company that would fix this for me.
Thank you.
Have you read this thread?

G4 bootloop: LG officially admits hardware fault, will repair affected devices

Hello, good news!
LG finally admits the problem. Then it will be easier for us to have our devices repaired/replaced! :highfive:
Some of you already shared links on several topics related to bootloop, I think it's better to create a new topic about it, as I wrote an article too for french customers
English: http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/ (official statement)
French: http://www.gamergen.com/actualites/...engage-remplacer-unites-defectueuses-269974-1
For european customers/people who bough it from UE reseller, no worries:
bel57 said:
P.S. furthermore, European Union stipulate under directive 1999/44/CE that it allows users to modify the software, root included. This modification *DOES NOT* void minimum warranty of 2 years on hardware supported by the manufacturer.
Voided warranty by "illegal" software modification has been classed as an unfair term and it's fought by U.E.

EDIT2: Ok guys, I *finally* got my G4 back.
LG PROJECT P1 (H815 - LG G4)
IMEI changed
S/N 505x => 602x
Repair: SWAP motherboard, software update (20D)
But would we all be subjected to the warranty? Otherwise it's not different from before.
At this point it seems like they just realized what the problem is after wrongly sending back a few units as 'repaired' even though it's still having issues.
"Customers who purchased their G4 devices from non-carrier retailers should contact an LG Service Center with the understanding that warranty conditions will differ. "
If you purchased your G4 from a third party website/eBay, it's more difficult to get your warranty recognized.. best is buying it via carrier, LG official store and recognized sellers.
Are they also going to apply the fix during the production of newer LG G4s? because if not, it sounds like all lg g4 will experience the bootloop sooner or later and will only repair it after it has happened
Yes, no detailed information about it, but it seems that they already changed the production process weeks ago and they're just late to communicate on the identification of this breakdown.

Well, I can't see any problem here. You need the original invoice, that's uuuh.. normal?
I just bought the g4 and sadly discovered that my S/N started with 505. Thanks god i did not unlock the bootloader. But I really want to unlock it to install custom rom. I'm thinking of sending my device to LG even if i didn't have the bootloop yet so i'll be sure not to get it after unlocking the bootloader and then having LG not repairing my phone. What do you think ?
Just use it and stop worrying, your device may not be broken as ours.. and no, you can't leave it to repair if it doesn't have the bootloop thing.
So where are all those people now who always wanted to prove not many people are being affected or it's a common thing to have problems when they first come in the market???? I wanna see their faces... I had to hear lots of things when I started writing about it. People made me believe maybe I am the only one annoying the surreal sound of the community. It makes me so happy to see this day which I was crying out loud to happen for so long.

Good to see this thread. My phone just died this night and since then is constantly hanging at boot screen. No access to recovery and download mode, no recognition by the computer (only a few seconds, then it restarts and gets disconnected) so no kdz flash via flash tool either. Just sent out a repair request to LG. Now fingers crossed it falls under warranty as I unlocked the bootloader. I purchased it in June and this is clearly of one of the first produced series which has the hardware defect, s/n starts with 505.
Don't worry, LG must repair this harware issue, no matter if BL is unlocked or not.
If you want to wipe or recover your data, try the freezer method. It works.

A lot of these 'people' don't really care or look into things until it happens to them.
Then all of a sudden there up in arms being your friend about the issue. It really only took a two second google search to see how widespread this is. On reddit there's a constant stream of bootloop posts if that's not enough proof.
Now? It's just crickets from the ones who were so keen on shooting this off as a small 'problem'. foh

I have a backup on the sd card from just a few days ago. I was aware something is wrong as it started to have charging issues, so I made one to better be safe than sorry.
Good idea :good:
Unfortunately mine freeze too fast, I just had time to retrieve my data then wipe all via recovery.. now it's sent for repair.. :crying:
But I can't do anything before this issue occurs? My s/n also starts with 505...My only chance is to keep fingers crossed?:fingers-crossed:
Yo don't complain as your phone is working great, just enjoy it and keep in mind to backup your data to microSD/computer. There's a small percentage that it will brake one day.
I remember mine overheated few times, and it may have broke a hardware component.
If there's nothing to report on your device, then you don't have to worry.

Why? Nobody knows what serials are affected or the extent of the problem. Keep daily backups (as you should be doing anyway) and worry about it if it bootloops. Here's a hint - it probably wont.

I don't believe this at all. 602 was basically the newest revision anyone could quote at the time that LG "Acknowledged" there was a fault.
There have been reports of 603 units with the problem somewhere. (On either Reddit or this forum, can't remember where)
Given the way that LG are handling warranty claims and not honouring repairs for boot looped devices which are rooted or bootloader unlocked.
I think its way more likely that LG have just realised that most devices seem to take around 6 to 9 months before they fail, its easy to cost manage the issue by swapping them all around with minimal repairs until all warranties have expired.
I doubt they are making any new G4's now that the G5 is out. They will be hoping everyone who has a failed device with no repair options will just upgrade to the G5.
Those of which move to other suppliers would be considered acceptable losses.

LG has never acknowledged anything.
No need when they already replace any faulty device under warranty. Can't get a warranty then look for another device that comes with one.

If its bootlooping how can they even tell whehter its rooted or bootlooped. I've read accounts where they've replaced motherboards and returned the device.

I've got one, no problems.
Its dual sim and the number of people with dual sim i find complaining about boot loops is minuscule. Mostly the single sim lot. I'll take my chances.
Guess what, if mine goes south, i use warranty. If no warranty left, i'll buy another G4 with warranty at half the price i paid when it launched.
What am i going to do with those leather backs and cases otherwise

The never officially acknowledged anything hence the quotes.
They unofficially confirmed to android authority that there was a problem here:
http://www.androidauthority.com/lg-admits-g4-bootloop-problem-hardware-fault-669603/
Unlocking the device requires submitting the IMEI/DeviceID to LG which they can use as a warranty blacklist.
AFAIK an unlocked device advertises its unlocked status on the bootloader which is visible before the boot-loop occurs.
LG have a root checking service called RCT which logs the date and time of any root related files/binaries to the /persist partition and I believe it also sets a flag in an RCT partition.
It builds a log file of which exact root elements it has seen eg su binaries/ busybox binaries forbidden file extensions and the date/time it detected the latest one of these elements.
Simply enter the hidden menu and find the RCT option to see your devices status.
LG can simply disable the faulty cores on a boot-looping device and check any/all of these.
The best way to hide root that I have read on here is to fry the motherboard by applying 24v to the battery contacts. If LG did refuse to warranty though you have absolutely no chance of recovering from that.

Nothing is undetectable.... The post I read this idea from suggested that this forced the device into the Qualcomm recovery mode (most likely the flash chip can not handle the 24v but the lower level hardware can).
Given that the source of the problem is a faulty solder connection to the flash chip. this advances the problem past the faulty connection stage to the completely disconnected/shorted flash memory stage.
If they cannot boot/read the flash memory chip at all they have no way to prove you rooted. providing you didn't unlock your bootloader.
Obviously if you push it too much, physical damage like burn marks would be a giveaway of foul play.
I read one user had been denied warranty due to oxidation on the mainboard... given the faulty soldering and thermal issues this could cause oxidation/residue on the mainboard.
Another user was refused warranty because a warranty sticker was not present on one of the screws of his device. (This concerns me because my device has no such visible stickers)
I personally have a 506 device tied to a 24month upgrade contract that I started in Feb, I usually bootloader unlock and root within hours of unboxing but read about this issue first and have kept my device stock.
I'm hoping I do not get a boot-loop but think its a matter of when rather than if.

if you're on a contract then you're covered for the 24 months. Nothing to worry about.
yes there is no root. That unfortunately is the situation we are in, every brand has some unnecessary drawback or other.
Well unfort i got a sprint varient but no longer with sprint. Im sure lg wont fix mine if it did happen. I cracked my digitizer about 2 days ago so now the phone has its first sign of damage. And knowing lgs good for nothin high and mighty butts theyll tell me thats what did the boot loop. And for them hoping ill upgrade yea rite never again. Ive been using my old internation edition note 1. Just because its rooted and custom recovery. Id rather go old skool than deal with lg any more.
Plus i thermal paste every device ive owned back since my og evo 4g. So theyll know ive been in mine.
Also as for the waranty sticker mine didnt have one either

The poll was there, but was removed 2 weeks ago, possibly new one will be back. Some ppl participated and answered that they don't have a bootloop, but later they had to change their vote and that was not possible... I don't remember the numbers, but the problem is also available on H818, many people go to the Service with it

It will be interesting if it starts again. I wonder why they removed it. Should have left it as is.
From the poll here, the ratio of devices with bootloop is highest with 505, fewer with 506 then keeps getting lower as the months go on. Yes there are some that have a problem but we don't know how many don't have a problem. They are quietly happy

1 year warranty in India too. 30k G4's imported. Number of Indians who complain about bootloop on xda ? can't find any. Why.
There have been other issues with earlier models, screen problems. One guy had the phone die. he said not bootloop.
Hong kong is another and Indonesia but again they say like you many, there is some noise for a month then it goes quiet.
But the single sim thread it never goes quiet.

With the help of google translate did a search on the LG section for the word 'butlup' (short for butlupnikov ) in cyrillic and found about 24 reports.
There is no pattern, only half of those 24 mention the serial#. Some earlier serials 505, 506, 507and some more recent ones 510, 601etc. The impression you would get is any number can bootloop which isn't what we found here.
Agree with what sergei says here.
In general, a matter of luck, like in any other phone. There is more panic, which somehow affects people. I, too, this fact forced to think about the choice of an alternative, but I did not find one, considering the price and characteristics. A camera for me is probably the most important point. None of the phone for the same price no camera, even close similar to G4 camera. The only option may be a Galaxy S7 / S7Edge. But twice the cost (comparing with G4 price) immediately makes to abandon its purchase.
