Help with LG G4 Model Number - G4 Q&A, Help & Troubleshooting

Hi,
I am confused regarding my LG G4 model number.
Because Under About Phone -> Hardware Info it shows LG-H815.
But when I connect it to pc & using adb devices, adb lists it as LGLS991e484402e.
Also LS991 0423 is printed on back of the phone near camera & speaker.
But under the battery the sticker with IMEI displays LG-H815 !
What is the model number ?
I need to find it in order to update it.

Are you checking for compatibility with a rom? If so, H815 is the number you're looking for.

Don't worry about the LS991 number. H815 is the version of your phone, the G4 international.

How are you planning on updating? Flashing a rom from xda-developers? If you're not sure, I'd recommend something like imperium rom, which is based on stock and has much the same behavior but is rooted with more options. Just make sure to download the one for H815. Of course, you'll need to have an unlocked bootloader and custom recovery before you can do this. Do you have custom recovery already?

Is there any way to install custom recovery without Download mode (& of course without root !) ? Because there is one more problem ! I cant get into download mode. If I use Vol up+ & insert usb cable then I get "Secure boot error 1014" & if i use adb reboot-bootloader or reboot bootloader phone restarts normally. Also fastboot mode is not working. Fastboot devices either do nothing or waiting for device ! USB debugging & OEM unlock is on.

The only method we have for our phones at this point is to use Download mode.... have you done some research on that error? Google or the forum search tool?

Yes I have searched for that & some related errors. But almost all of them says that it is because of locked bootloader & to unlock the bootloader I need to enter fastboot mode (Not working as of now) also I have tried many drivers mentioned in the posts (LG universal, LG WHQL etc), LG Bridge, LG PC suit, LG flash tool, LG mobile support tool etc & Also tried the same things on Windows 7.

I don't really know much about fastboot problems, you'll have to look elsewhere for help. Sounds like that's your next step, though. Look for people who can help you get fastboot/download mode working.

[Q] Get imei by adb or fastboot H815

Working on a G4 H815 5.0.1 un-rooted how can I pull its imei using adb or fastboot getvar ?
tried:
Code:
getprop gsm.baseband.imei
dumpsys iphonesubinfo
gsm.imei
ril.imei
ro.gsm.imei
but I get no output
using
Code:
adb shell services call iphonesubinfo 1
I get a long HEX and the imei but I dont know how to parse it using Batch commands
also on htc devices I know there is
Code:
fastboot getvar imei
but its not working on lg maybe there is an alternative ?
Hi,
I know you are asking the question about through ADB or Fastboot but you are aware you can get the IMEI number through the Settings, General, About phone, Status section?
Regards,
Ravi
Yes I know that, I just want to know how to do it programmaticly
Actually this is important to know because my locked bootloader LG G4 H815 is bricked. I need to unlock its bootloader (to flash TWRP custom recovery) but the unlocking procedure requires to enter the IMEI number.
My phone goes in to Download mode. So any one who can answer the question asked in the OP.
Update: I guess IMEI would also be written under the battery as well. I don't have the phone right now. Will check it out first.

Hold vol up+vol down+power, all three buttons, until display turns on and shows IMEI. Since you have non-removable battery, I guess you don't have LG G4, but you can try this method, it works on G4...

Those codes are ROM dependent and you're using a brand new version (nougat for your device is just a few weeks old)
Maybe try
*#*#06#*#*
##06##

Cannot boot into bootloader/fastboot

Hello guys I have H815 and I can't proceed with unlocking bootloader cause my phone cannot boot into bootloader/fastboot mode. I'm not newbie, but with this phone everything goes ****ing different than in instruction.
I the instruction there is adb reboot bootloader. Of course my phone is seen in adb mode but after this command it just reboot to system. I tried also key combinations with no luck...
What to do?

Hi,
I'm the same...
looking for solution I found this on Youtube:
Pratically, you have to press vol up while connect USB on PC....
I haven't the G4 with my today and so I cannot test if this is a valid mode...
If you do this, let me know if you can enter in fastboot mode

I did that and yeah it entered this mode but it's not valid bootloader/fastboot mode. It's some service mode to update firmware. Anyway it's not visible in pc as a normal fastboot and I cannot proceed further with unlocking bootloader...
Edit: it's download mode... So as I said it's not fastboot mode.
Anyone can help?
Seriously nobody? I thought this phone has good community and support...
I'm facing the exact same problem with my H810 on 6.0. Sick of not being able to root atleast.
Seriously hasn't anyone on earth found a way to boot this **** in fastboot? I mean there are a number of tutorials but everything goes different as F*** with this thing. Hope someone will update with good news. :fingers-crossed::fingers-crossed:

Thanks yeah I checked but that's for ARB<=2 devices. I forgot to mention earlier this godforsaken thing is ARB3.
I have an H811 (T-Mo) running firmware H81120p, ARB3. Doesn't seem to be much that can be done with it as far as rooting. It also has no stock recovery, only boots to system.
you did follow this official guide right? it unlocked mine after a few angry moments
http://developer.lge.com/resource/mobile/RetrieveBootloader.dev
use minimal ADB https://forum.xda-developers.com/showthread.php?t=2317790
Only way to boot twrp later is to use fastboot with ADB, recovery with buttons doesn't work.
if the device wont boot a rom use adb to get back in recovery.
if you use bank apps, install magisk before installing rom, do not get SU

Only problem is that the info linked to above applies to ONE G4 variant only - the H815 international model. The rest of us are SOL. The bootloader on US carrier G4 - AT&T, T-Mo, VzW, etc (most later firmware revisions for G3 as well) models has been nailed down. The only exception is a G4 with ARB <= 2 can be hacked with UsU in order to root it and install a custom recovery.

Tmo is very easy
Go to dev options and enable adb
Then run "adb reboot bootloader"
Once there, run "fastboot oem unlock" and voila, you have an officially unlocked bootloader with no restrictions related to UsU
Please be aware the above will factory reset your device

Why v20o
Remember, this has nothing to do with UsU and therefore ARB etc doesn't matter
Edit: ps there are loads of H811 users in my Lineage thread and the other ROMs too

Got it. Guess that it makes sense. ARB prevents rolling back to earlier release than 20o, I'm ok. Will try the BL unlock today then.

I actually managed to get my LG V20 F800L into same situation after messing up my rooting process.
First i was stuck at logo and factory reset did nothing. Bootloader was working then.
Then i downloaded new firmware through "Download Mode", and after that i lost access to bootloader.
I know the phone model is different, but process seems to be very similar for all LG devices.
Trying to troubleshoot that atm, if i'll have results i'll post them here.
P.S. I know original poster long left (probably after throwing phone into a grinder), but maybe for someone with same problem as us in the future the info will be useful.

Ok, now i have to reply to my own post, since i believe i understand now something important:
LG phones usually dont have bootloader open to access. Until you use some exploits to do so.
I did not know that at the time of writing that reply.

IMEI LS922 / ROM AS922. What to do?

Hi guys,
So I have and LG G5 that I bought recently and when looking into IMEI online I find that my model is LS992 but on my "About Screen" and even firmware it is AS992.
I wanted to flash back the LS992 using LG UP and everything, using "Upgrade Option" but an error shows: "Can not because of LS992 -> AS992."
I need to add that i want to get back to the LS992:
- because with this build i dont have tethering, even with Shareit
- need to reboot the phone everytime so it can be detected into my PC.
Any help would be much appreciated.

have you tried fastboot oem unlock and flash with fastboot?if fastboot isnt working for you, you should try it in linux, this is what fixed my bricked prestigio tablet.
or try the chipset flashing software?
also this: https://forum.xda-developers.com/t/...nload-mode-after-ota-on-rooted-lg-g2.2582142/, and if this doesent work i think you can try shorting the pins on the motherboard to get it into flashing mode, there is always a way but takes a long time researching and trial/error,
im still trying with my device ill post here if i fix it
