i have my LG G4 H815 bought it from China (refurbished) running Adroid 6 MM,it used to work just fine till i upgraded it to MM from LP, now i don't get any signal from any carrer here in Tanzania East Africa, i have read so many threads with no solution, i wanted to unlock the bootloader it doesn't work since lg says my device doesn't support it, i was curious may be i can find a way to make my device work again or any way to install a custom rom or root it may be i can edit a build prop.
Current Software Version is- V20-OPT2-HQ
any solution for signal will be grateful.

I bought a LG G3 here at Brazil (version D855P), but when I flash the European firmware (UK or Germany), it doesn't get the HSPA+ technology, just the HSPA. It's a lower connection velocity, so, I want to know why does that happen.
And how I can solve this problem, because I didn't find anywhere how to flash different modems on the G3, if that was going to solve anything...
I want to do this kind of change because of the carrier customization on the phone, that I managed to get rid off some things, but remains the wallpaper and home page of the browser.
Waiting for the replies, thank you.
Hi guys i had LG g4 h818p which was dead after bootloop issue

So guys please help to get google services and apps without harming the device

Can you see the serial number of the new motherboard from Aliexpress?
From which country are you, does it have problems with frequencies as the motherboard is from Chinese variant?
I had flashed (accidently) chineese firmware on one h818p, then flashed another one via LGUP and everything went great, so you shouldn't have any problems
Yes, but you have device (H818P) which supports European frequencies. If I order Chinese variant from Aliexpres, maybe it doesn't support EU frequencies?
Another question is serial nr., because if I get some with 50x, who can guarantee me that the bootloop issue wouldn't happen again?

If it's the same model, you should be fine after flashing European rom, nobody will give you a guarantee on bootloop issue and there is a high chance that it might be a refurbished or repaired board.
Well, from Aliexpress site it states that it's only H818 model, nothing else.
I have dead/bootlooped H818N from Hong Kong which worked well in EU countries.
Before anyone asks, yes I've searched, but have not been able to find any solid answers. So here I am. I just bought an LG G4 from ebay, I was listed as a T-Mobile model but when it arrived, I discovered it was a US model H815. It's running vx10b-eur-xx. These apparently have locked bootloaders. My question is, is there any method I can use to root this device and run a ROM like CM14, or am I stuck with what it's got? Like I said, all my searches never really come up with a for-sure answer. (hopefully this is in the right spot)

i think theres no american h815 i would returned for misinformation.
no cm only root if you are on lollipop.
unless its one of the europeans models that can be unlocked. serach for LG G4 than can be bootloader unlocked and chek if yours is one.

Apparently there is a US Variant H815, when I attempted the unlock the bootloader the LG developer website stated that the device could not be unlocked because it was a US model. Not the exact quote, but close enough. Thanks for the reply though.

Hello,
i got an LG G4 H815T variant , it comes with android 5.1 , after upgrading with LG bridge to H815T20e_00_0829.kdz (android 6) , i the phone is not detecting any mobile network, just searching , and nothing .
i tested to flash many kdz even back to original stock room , but same issue , cannot find mobile network , is it a problem with the modem image ?, i wanted to unlock the bootloader to try on cyanogenmod but not possible for this version (H815T hong kong).
my phone is actually rooted , what can i do more to resolve this ?
thank you
any progress ? are u fix it ?
Hello.
I am really happy to join the community. It's been several years since I browsed the forum in quest of precious informations and have never dared to take the plunge. So today is the opportunity for me to expose my problem. I ordered a LG G4 (refurbished) on Aliexpress and in System > Hardware info it's indicated as being H815TR (Turkish) but the IMEI check indicates that it's a H815 for the European market. So, I try to flash "v20i-h815.tot" and "v29a-h815.kdz" (European files) with LG UP but get a "invalid file" error. I have no problem installing the "v20i-h815tr.tot" and the "v29a-h815tr.kdz" (Turkish files). On the off chance, I tried to unlock the bootloader officially and had a mismatch (IMEI / Product ID) but LG made the necessary for me to get the "unlock.bin" file. My LG H815TR is perfercly unlocked and I have been able to test some wonderfull customs roms especially the H-Rom V30 PORT V2.2 (Thanks to Astrako). Unfortunately from the beginning, I cannot activate the FM radio (no sound), this restriction seems to be a special feature of the Turkish version. In hardware info, it is always indicated as an H815TR. Do you think it's possible to convert it completely into an international H815 from TWRP ?
Thanks for your attention.
