I have a unique version g4 and am stuck in "ILAPO" with no warranty.

Hello. i have a few posts from a while back about rooting my g4.
It turned out i had some weird beta version of the bootloader on it but i was able to update and root it still.
Well, now just a few months later. My phone just starts restarting over and over and will not boot past the lg logo.
After some research i found that most g4 made before September of 2015 had this problem.
So i contact customer "support" and they cant find my imei in there system. After talking to 3 different people one of them finally said that it shows my phone is a beta phone made in 2011 so they cant honor a warranty.
They said that they wouldn't even have the parts to fix it if i were to pay.
They told me to contact lg Korea but couldn't give me any help in contacting them.
Anyways. I came across the fix https://www.reddit.com/r/lgg4/comments/45gfg2/dae_g4_series_msm_big_core_disable_tool_guide/
But it appears that my phone model h810 (att) is not supported.
Also im pretty sure i was on marshmallow (honestly cant remember).
Is there any known fix for the h810 that anybody knows of?
And if i try this and it does not work, will it prevent me from being able to recover my data if someone does make a port for it?
I downloaded the zip but i dont want to flash a tot for another phone on here yet.
Any help would be appreciated.
Thanks.

I doubt it is an 2011 year model. Look at serial number behind battery. The first three numbers are manufacture date - for example 505. First number means year (5 - 2015), other two are month (05 - May). Maybe you might have provided Serial Number rather than IMEI for them.
As you still have locked bootloader, contact the place where you bought it as you should still have guarantee. Either they will take it to fix it or they should give you contacts for authorized repair.

to make the modded KDZ work on your at&t you need to renamed with hex program phone model. the kdz is for h815.... read this page..
http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734/page72
well you need to be on LP if you were on MM.
i guess youll still need to downgrade anyways. to be safe..

My serial starts with 503, when i first got it it had software vo9e but i updated since then.
Im not sure where they came up with 2011 but it would make sense . maybe 2013 as a beta test phone.

yeah sort of .. thats whati understand... once you do please let us know. as i have h811 and would like to have this just in case.. kncok on wood

Yup. Now its really a brick. Dont try that.
Cant even boot into upgrade mode now.
It will vibrate as if it was turning on. but wont even show the lg screen.
Should have just put it in the oven. That made more sense.

no. There is a not problem on the motherboard. I encounter this error only???Nobody from else not was.
It is using a lot of people the roots.

G4 Dead Software

I`ll keep it short: I rooted it, wanted to do flash something without unlocked Bootloader and now it wont start, and also the Download Mode doesnt work anymore...
So I just wanted to know, where is the Software saved on? Do I just have to buy a new Motherboard, some other parts or can I alredy sell the phone with no hope it will ever work again?

Unfortunaly Download Mode doesn`t work... I do have warranty, but I dont think LG will even try to fix it, because it`s my fault. ..

In my opinion no its not worth the hassle but ot only takes 5 mine to check ot 2. Unless its got the bootloop issue or hard bricked its fixable. But how determined are you.

my phone boots up completely but no baseband no imei or anything and that infamous 9008 brick is fixable with ls991 laf.img and 8992.mbn and etc... files and here is my next approaches please if you have enough aknowledge guide me with these options i have or add any if something came on your mind:
1.Flashing a ls991 model kdz and see what comes out(probably not doable,lgup may not let me flash it)
2.while surfing through the forums and threads i found the exact H811 10N Laf.img and i will replace it with ls991's and will use QFIL to correct the partitions and then my phone would be fixed(im too scared for this one...maybe my phone is a refurbished F500...who knows? :fingers-crossed: )
3.Maybe finding and flashing F500 laf.img fix the phone but a HUGE problem i am facing:where to find that file?
Note:All i am trying to do is to fix this phone by software approaches and disassembling the phone is out of my options for now(only will do if none of above fix it properly)
So with all of that what would you do if you be in my shoes?:cyclops:
Always hated LG and admired Sony but i started to hate xperia x series because of weak development so i bought this one for around 100$ in your currency.:laugh:

Id send it back.

My curiousity will kill me someday
I believe i can fix it and beside that learning new things about lg devices is interesting since i bought it for only 100 bucks from an old pal who does nt know what actually smart phone is:laugh:
Anyway i learnt how to extract laf from kdz files and im going to test both f500l and h811 and pray:cyclops:
if i fix it properly i would make a thread to share my experience with this refurbished(dont know actually if it is)

then i will use them to crack open kdz from both H811 and F500L firmwares to flash laf and other messed up files with fastboot
but im wondering which one should i try first because im concerned if i flash wrong files then there will be even no 9008 mode to use QFIL and get back to very first step...
What is going to happen exactly when i flash another varient's laf? will it kill the phone completely or will there be any 9008?
Thanks for those apps you mentioned btw:good:

Actually LG devices are very easy to disassemble so people like them wont put so much effort to refurbish LG phones and earn themselves some easy money.
And believe me Iran is the heaven of refurbished and chinese phones
Mostly because many cant afford to buy their phones and other stuff from trusted sellers and they buy them with no warranty(or guarranty)from third party sellers.
Actually they have a place for themselves in downtown(Aladdin building).
But i wanted a flagship LG device to learn more about it and i got it for a couple of bucks so it really didnt matter if my G4 didnt work as expected.
But its always a pleasure to make some mystery and try to crack the case by yourself :laugh:

of course they are great but hardware faults are pretty big deal but for me sony z series were better right until z3+ .for now im happy with my htc u11 and im not going to unlock it or anything.
maybe i use g4 as my secondary device instead of xperia z2.
its a shame that sony is not in its golden age (2011-2013) anymore...
will make a thread to help people like me to unbrick their refurbished device
Thanks for everything

i bought an LG G4 with a model number of h811 but with sprint serial number

Dear fellow XDA members i bought an LG G4 H811 and when tried rooting it with no luck by pure luck i noticed that the serial number starts with ls991... Now the rom is 20R as a normal T-Mobile phone ... Anyone faced this issue before ? If so how do i root this phone ?
Thank you

first you dont know what you have.. i suggest to open the phone and take out motherboard. see plaque model if it says h811 then you have h811 if its says ls9 then you have sprint.. thats the only way. they maybe edited software easy to do.. but you can not change model in plaque ..

Ive tried to get it to go to the bootloader but it simply restarts without going for the bootloader and im not quite sure what i can do next.. Any tips ?

Sounds like a two part phone.
Has been refurbished..... Most likely sprint motherboard.....bad news

Same issue here but my phone is a refurbished f500l
I suggest you to not customize anything because there is nothing good when it comes to customizing a refurbished phone even flashing official kdz just let it go or you would be in your worst case of customizing
But if you insist you may want to search about qualcomm 9008 mode a little
Best wishes.

I have battery issues too its lg bloatwares but you should have root to modify system and remove crapware(some of them can be disabled through apps menu)
First,try some apps like kingo .etc and see if those apps work because king root worked for me when i had h811 10n rom however its super user app is nothing but bull****...it will do the trick on the other hand.
Second(which i really dont recommend),try low effort root and injecting rooted system with send command and adb search for it in this forum and you will find it.
What i strongly recommend is getting along with it
Because this phone does nt worth the hassle to modify any thing on it if you have a refurbished device
Peace✌
