Can I still flash broadband if my phone d855 has no root and a locked bootloader?

If so, how?

Thx
[G3 General] MESA:
Flash kdz and you will get different baseband
[G3 General] darkenoid:
I have locked bootloader and unrooted device with latest update of software.

Can't figure out have to root or unlock bootloader.

Thx in advance.

can't get my phone in download mode
[G3 General] MESA:
Read how to flash a kdz with LGUP and stop writing blindly. First get some info. :)
[G3 General] darkenoid:
Now I really messed up.

The reason why I wanted to flash different rom was because my internet connection with T-mobile suddenly started to work very slowly, I wanted to try different baseband. Secret menu didn't help(where you choose among verity of different basebands). So i decided to flash.

First I figured that I had locked bootloader and no root.

I was able to root phone with kingroot (was very surprised). And than I accidentally deleted boot partition (so I think).

So now my phone is only visible as Android device in windows device manager. I can't find the right driver to get windows to communicate with phone anymore, adb fastboot finds nothing.

Phone only starts in fastboot mode, no matter what keys and power button combination you are holding.

Now I'm despair and cry for help.

I have lg g3 d855(I assume international edition) where do I go from now.

I guess I need fastboot driver that I just can't find. or I just need to install it manually. I installed latest lg drivers and sdk.

Help!
[G3 General] dcop7:

[G3 General] dcop7:
Can you use ADB?

You can use ADB to push a ROM to your device.

If that doesn't work, search something like this: https://www.google.pt/search?q=lg+g...TAhVMuBoKHUoBCkoQrQIIaigEMAw&biw=1459&bih=534

All I can do for you is search, and that you can do it self :)
[G3 General] darkenoid:
I spent whole weekend, basically wasted in search of solution. Think now would be better to ask. If it's still not to late to fix this.
[G3 General] dcop7:
lets recap.

The phone only boot to fastboot.

The download mode is not available. Right? The volume up thing

I saw some of the threads, my current state ONLY fastboot, in windows device manager it said android device, with a question mark next to it as it`s driver is missing.

Prior to that adb worked fine. no adb does not sees the phone.

Hi all,

Does any one know where I can get this Radio/Modem from. It's from LG G3 D855 version.

Baseband version MPSS.DI.2.0.1.c1.13-00111-M8974AAAAANPZM-1.44479.1

Originally released with Android 4.4.2 (KitKat), then in 2015 Optus (Australia) updated to Android 5.0 and removed VoLTE. Just trying to get it back.

Thanks in advance

[G3 General] KobajaZeus:
Probably a dumb question, is it possible to use kitkat modem with LineageOS 14.1 so it can be paired with kitkat stock rom in multirom?
[G3 General] bolo59:
I confirm 21c is perfect and works for the D855-30c firmware

and I take the opportunity of this reply to Thanks and congratulates Step-Han for his/her very didactic post, because flashing the 21c modem has completely resolve the following problem in my case (I describe it in details below so it may be useful for some people in my case):

First, I'm running a D855 model (suffix 6RF) bought to Orange carrier in France. The D855-30c firmware was pushed by Orange to my device by OTA a few months ago. I did not flashed any other ROM but I gain a root access using the "classical" procedure (Kingroot, then TWRP v.3.2, then flashing hacerpermissivo.zip, then beta-superSU-2.52.zip).

After obtaining root access, everything was okay except 3 things:

1/ the 'about the software' page of the parameters was freezing;

2/ On this page, baseband and software version were 'unknown';

3/ Most of all, there was a total drop in the network signal (WiFi with or without sim, as well as cellular and data with sim), which occured almost regularly every 40 seconds. This issue let the phone unusable because every phone call was broken and Internet access was completely unstable!...

I was afraid this was caused by a hardware issue on the antenna (because I eventually once opened the phone to perform a short pin on the EMMC because of a hardbrick issue which had been resolved), and I also wanted to make a clean wipe and flash a stock ROM (I was really unhappy with that option because I just had spent 2 days for reconfiguring my whole environment !...).

Fortunately, my recent reading of the present thread came on time !... I first flashed the 30B modem, which did not work on my system (totally unrecognized Sim), then the 21c, which works perfectly to now, with the network signal bars being constantly displayed... BTW, there was no need to flash any RPM or TZ partition.
[G3 General] Heartburst:
I need to restart my device several times to get it to detect a SIM card. Would the baseband have anything to do with this?
[G3 General] ANDRESOTE_8:
LG G3 D855P (isn't a typo; is a D855P, not a D855)

Hi, everyone. I'm Andres, from Bogotá (Colombia).

I have got a LG G3 model D855P (see the "P" at the ending of model code). It is nearly the same D855 Global LG G3 model, but D855P is designed for South America adding support for LTE band 4 networks (1700 and 2100 MHz).

Here in Colombia, i have a data plan with a carrier named Avantel. It operates using LTE band 4 and using GSM/HSDPA/HSPA+ at 850 and 1900 MHz frequencies. Then, i need my D855P keeps the compatibility with LTE band 4.

I want to install Lineage OS 14.1 on my G3 D855P. Lineage's website shows ROMs for various LG G3 models, including D855, but no D855P.

I have already installed TWRP 3.2.3.0 successfully from TWRP official site. Also, i downloaded all the published Lineage OS builds from the official site and i tried to install each one of those, unsuccessfully.

None of that builds doesn`t allow installation, and shows the following error message:

ERROR: it appears you are running an unsupported baseband. assert failed: g3.verify_baseband("21C:MPSS.DI.2.0.1.C1.13.2-00002") == "1"

My question is: if i flash the Step-Han baseband, will my D855P device keep compatibility with LTE band 4?

Additional information: I tried again the installation of Lineage modifying .zip folder erasing the 2 first lines into the file named "update-script", and i tried again to install that modified .zip Lineage ROMs file in my D855P, and that shows another error message (something like verification errors of the .zip) and each installation was interrupted.

After that, i have succesfully installed Liquid Remix ROM from XDA (a ROM based on Lineage OS 15.1 for LG G3 D855) on my G3 D855P, and it works perfectly with LTE band 4. At the moment, i found only one bug; the ROM does not detect the ambiental light sensor, then i have to adjust manually the display bright. That sensor was working very well when my D855P was running Android stock firmwares, and i don't think the light sensor is damaged.

Wrong....you can keep your current radio/modem and flash ROM by your liking and compatibility with your G3 model...Only thing that is a must...modem that you have must be from Lollipop firmware if you flash Lollipop Rom and it doesn't matter if it's stock or custom(CM, Aosp)....It goes the same for KitKat....KitKat rom + KK modem/radio ....that's all that is different ;)

Hey [MENTION=1952114]Step-han[/MENTION] I was wondering if you might nod me in the direction where I can find a radio for my D855 that you don't actually have in your list?

There was a version of 20i that came after 20p released, for the UK market. here's a thread relating to it http://xdaforums.com/lg-g3/general/update-v20i-t3124928

[G3 General] ClownShoes:
Oh really? No difference?
[G3 General] Step-han:
No, not any difference. I live in the Netherlands and did some WiFi tests:

20I (00048 from UK .kdz):

Download: 14.15

Upload: 12.60

On the same WiFi and same location in my house. Did the test 3 times and this is average score.

I've uploaded the 20I (00048 from UK .kdz) for u on mega but I'm not posting it because its the same as the 20I version there. I'll send the link with a PM.

[G3 General] phileg:

[G3 General] Step-han:
Try 20P modem (00052).
[G3 General] darkneo-:
As far as I tested the basebands, it seems like the 0050 (20k) is the most accurate baseband in France. Better sync for 3G/4G and better GPS accuracy. The 0052 (20P) is good, but less accurate than the 0050 from my point of view. Also ensure that your G3 is correctly set for the network preference (Prefered Network Mode set to auto 2g/3g/4g).
[G3 General] Marcovanbasten:
Agreed, k better than p also for me.

on a side note i also now know how to root and install twrp (scary but straight forward enough).

So I just got the G3.. Installed CM12.1 but reception poor in house compared to my previous device.

Flashed 00052 (20p) over a 00048 modem. Data speed is about the same in 00052 but reception bars increased a bit. An average of one bar I would say, but it's not hard stats...
