Hi guys, I just bought a LG G4 and Im very confused with the s/n on the box. My serial number starts with 506 which means it was manufactured in June 2015 and therefore there are big chances I got a bootloop defective phone. LG G4 users have been dealing with an annoying bootloop problem with their devices for the past few months. The device apparently reboots randomly and gets stuck in a bootloop. Having no solution. Last time I was dealing with deadzone issues on my G2, but now we are looking at the notorious bootloop issue on the G4. Here's my current scenerio: I had an LG G4 H811 with starting IMEI 352 that went into to bootloop recently. It was unlocked, so not under warranty by LG, so I tried the cold/heat treatment to get my stuff off. My LG G4 has recently become stuck in a boot loop and become unusable. This seems to be a very common from all the info I've been seeing, and the cause is apparently a defective motherboard.

Finally my turn. Bought at august 2015. Boot loop loop loop. Hi I'm thinking of doing the same as you because my G4 is on 511 serial number and warranty expiring on 30 May 2016. I bought my dual SIM export set in China in August last year. 3 weeks ago it died on me with the same boot loop problem. I called the local LG. See your box to know your G4 serial number, seek for the first 3 numbers. 505 = 5 is the manufactured year, 05 is for the month. Here, in Indonesia, if you have this issue, LG will replace the motherboard for free.

LG G4 serial number and manufacture date questions

Hi guys, I just bought a LG G4 and Im very confused with the s/n on the box. My serial number starts with 506 which means it was manufactured in June 2015 and therefore there are big chances I got a bootloop defective phone. Buuut, inside the box and behind the sticker with the sn there is another barcode with other numbers that says: MAY67xxxxxxxx(1.0)BL, but thats not all, I opened the box and turned the phone on and installed the LG phone info and lg phone from app, both app showed that the phone was indeed manufactured in June 2015 but both show that the phone release was in October 2015. I contacted the developer of the app end he said that the 'realease date' is the date that the phone left the factory, which is quite weird that the phone was manufactured in june 2015 and only left the factory in october 2015 (about 4 months later) Now Im very confused. Why was my phone in the factory for 4 months? maybe they held it to fix the bootloop issue? what is this MAY67XXXXXX number in the box? what does that mean? is there any other method of checking if I have a defective board other than checking the serial number in the box (506xxx...)? help me please, If I cant find any proof that the phone has a new board other than the 506 sn board I will return the phone, I just find it shity that we are in December 2016 about 1 year after LG admitted the issue but they are still selling the defective phones. please help. here is what the box number looks like: http://imgur.com/sc7vrbV
