{FIX} No Network After Update to MM {LG G3 D855}

Hello All,
After many attempts for several days to fix this problem after update to MM, i found this way and it's works perfect with me.
1.. Downgrade to lollipop 5.0
2. Root your device and install TWRP recovery
3. install CandySIX Rom
4. Try connect to your carrier network (at the first time it not give you anything ) , try several times
5. Reboot your device now , you will find that your phone connect to you 4G carrier
6. Install CloudyG3 2.5
7. Enjoy
And now everything works well and the problem resolved.

I tried this fix but id didn't work for me.
I have an LG D855 which I bought from China as EU model. Unfortunately it is probably not.
After I install Lollipop, I get the well known "Current version not avaliable for user!" message. Then I installed CandySIX ROM (the latest 1.1 version) and I got the same problem as with CyanogenMod. If my SIM is inserted the phone will hang (with screen shut down) a few seconds after boot. Without SIM everything works fine.
Which versions of ROMs (stock 5.0, CandySix) did you use? Any other advises what should I try?

You had a D855 Taiwan version not a Euro version !

Sorry for my late reply. I was at holliday and didn't have time to check it until now. I don't think my phone is a Taiwan version. According to IMEI the region code is A6GBTN. So it should be a Great Britain phone I believe.
I checked what is the latest firmware for my phone, downloaded the KDZ and installed it using LGUP. But I'm getting the same error. I do believe my "misc" partition is messed up. What could I do?

Look , i don't think that you have a problem with IMEI, it's normal thing to see IMEI and IMEI SV.
you need to try all possible ways to fix it including my way.
Look at this thread [RADIO/MODEM] [d855] LG G3
then choose another modem like 21C ... I'm on 20A modem and everythink works well with me.
Good luck Bro.

On marshmallow rooting requires an unlocked bootloader due to new security measures, so thats what you need to ask for first. Currenrly only the european h815 and the t-mobile-us h811 can be unlocked.

I'm gonna need some time to work through getting all that setup. So I need to boot into that Linux, install Salt, unlock with UsU, Install Custom Recovery and finally root the darn thing

That's why FWUL exists. It is fully android compatible and has SALT pre-installed (just do an update when starting SALT and do a backup before doing anything else)

H815(SEA) Unlock.bin

Hello guys, Im using South East Asia(SEA) variant of LG G4 and few times ago SEA variant owners were able to get Unlock.bin from LG Developer site. But now you can't get access from the LG Developer site.
Therefore i need a Unlock.bin from a SEA variant

So you need someone that can access the website of LG developers and give you your own unlock.bin because you can't ? Or just wanted a random unlock.bin (this can't unlock your device)?

Will doing something like that can unlock bootloader, I mean if we edit unlock.bin and put our device id will it unlock the bootloader there is no further security.
Please update me on this I also have H815 SEA and I would also like to enjoy CM if this is possible.

They have said officially that H815 SEA don't support unlocking bootloader, it happened for a short period of time which was meant for internal testing purpose.
Now I don't know what else can be done.

I could try myself ?

Flashing a 811 kdz should work in term but high rate of failure and hardbrick. It's the only way that we could use to unlock !

I'm planning to flash a turkish kdz version numbered of v20g. Creator of the thread says it can be flashed on every variant

[REQUEST]V29A kdz/modem

It has been discussed multiple times already, but I thought making a new thread will get more attention and maybe result in success.
Please send the beta nougat V29A modem (or kdz) if there's one available.

I'll try to contact the person who has the update through YouTube

Would be really great to get the polish beta extracted for our devices. Mine is H815 and I can't wait to flash Nougat...

Waiting for the damn kdz from Argentina ... I hope it arrives soon. Long live the G4

If someone manages to get a hold of it, let lg-firmwares.com know. We're all itching for this update to happen.

Does the ROMs for the G4 (h815) works for the G4 (h815P)?

Hello, i have an old LG G4 (h815P), and i want to install the CypherOS ROM, but in the page only mentions the model h815. Anyone knows if i can install that ROM on my device? Thanks in advance.

You need to unlock your device in order to install custom ROMs.
As you own a device which cannot be unlocked officially UsU is your way to go then.
After that: yes for sure you can install cypher for the 815p

It will work yes.
I have an H815p and it works for me.

Actually... h815's have the highest success rate for UsU unlock. My 815T was a piece of cake to unlock, dear
