[Q] [HELP] change baseband

is there a way now for lg optimus g to change baseband?
I bought LG optimus G F180K (KT version -olleh), I'm from Philippines btw. I can't get 3G even with the original device setting. I flashed E975-10a firmware which I downloaded from the LG site for firmwares. I'm sorry I'm noob about this. I flashed the KDZ file without unlocking the bootloader, is that ok? Anyway, everything went well, but still I only get 2G signal. I think I need to change the baseband in order to get 3g or 4g. HOW DO I DO THIS?
Thanks!
Edit:
BTW my current baseband is APQ8064/MDM9x15M
kernel: 3.4.0
build #: JZO54K
I read somewhere in the forum that after he flashed the E975 firmware on his F180L device, he then flash the orginal baseband for F180L. Can someone provide a flashable baseband for F180K? I would greatly appreciate it.

I got this from another thread

Sure, you must do this.
First: Root, Enable USB Debugging, Download this file: (I can't post the link since I have less than 10 post as of now)
2. Copy this baseband.img to Internal Storage (/sdcard)
3. Run file flash_baseband.bat
4. Follow the guild.
5. Your phone will reboot and finish! :victory:

Here they simply flash the baseband. Is there someone out there who would generously share the how to flash the baseband for F180K?

i own an lg optimus G e970 at & t version on ics
i rooted it.... installed slick JB on it http://forum.xda-developers.com/show....php?t=2084431
but forgot to install the modem via recovery.... so when i turned my fone ON, i had carrier network signals available but wifi was not working....
i downloaded a KOREAN kdz for f180L and tried flashing it on my e970 via R n D tool...it was successfull but when my fone rebooted, it was country locked (required some password at the beggining)
so then i started looking for the other kdz,s available online (as i was specifically looking for kdz for at & t LGOG)
then i found a brazilian kdz for e977 and flashed it to my fone via R n D tool and my fone booted up.....everything working but no network signal showing a sim error icon in status bar
edit 1: finally i got the LGNPST to work and flashed the stock at & t rom but still it shows "no sim card"
flashed a different jb radio...its getting weak signals
working on it now
may be need efs

Your phone probably doesnt supprt the network frequency that your carrier runs on

before flash works OK, problem with network was after flash official ROM

same problem here before it was fine after flashing cellular service keeps on dropping

Hi guys, I'm facing the same problem. Did you find solution?

LG G3 LS990 Hard Brick/Wont Turn On/No LED No Light/Black Screen

hi, I tried T-Mobile version of CloudyG3 2.2 ROM on my LG G3 LS990, when it asked for a reboot, I rebooted it and since then its not turning on anymore, there is no LED, no screen, nothing. I tried many times to press and hold power button and combinations of volume up and down keys, no luck. Before the ROM update it had good amount of battery, more than 80%.
However when I pluck it in with my computer, Windows detects it as "LGE AndroidNet USB Serial Port (COM41)". Thus I got luck. I changed it to COM41 and tried to flash it ZV4 TOT using LG Flash Tool, but it says as below:
--------------------------------------------------
PID: NULL
IMEI: NULL
Model:
DLL: LS990
BIN: LS990ZV4_04.51101.TOT
SWV:
SWOV:
Model Information Check FAIL!
00000000
--------------------------------------------------
I guess the T-Mobile ROM might have updated its model number somewhere or did some changes. I used LG Flash Tool before and used ZV4 TOT to unlock my phone, and it was working fine with bare-pop ROM (LP 5.1). Then I thought to try CloudyG3 2.2 with another variant's ROM file since it doesn't have any for LS990 yet.
One more thing is the when the battery is removed and phone is connected to computer, there is a sign on the phone-screen, that says battery is not present. So the screen is fine I believe.
Thanks and will appreciate if someone can help to fix my issue.

Did anyone find a fix for this? My phone is in the same boat

Makes sense that your phone is bricked because Cloudy G3 currently does not support the LS990.
Keep trying to enter download mode.

I had the same, I edited the tot file, deleted the d855 (in your care ls990) and I avoided this error but it didn't flash.
I suggest you seek for the qhusb 9008 fix, boarddiag etc. It's actually pretty easy (but you have to open the device)

Have any of u used the guide here. http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359

Fixed through JTAG
I had it fixed from a guy using jtag. Had to pay him $30 though

Guys there is a guide to fix this on your own no jtag and free i dont want to sound like an arse but if my phone is bard bricked the data on it is the lease of my worries yes this method also wipes all data but its garuntied almost all varients and look while its apart u can do the thermal modd with the paste or pads on the chips the guide says ls990 but this will work so far on all that has tried furthermore u should have your backup apps pics and all backed up throught twrp and save it on your ext sd card so after u fix the brix reroot install twrp and restore bam all ure dtatas back

is any body fixed this problem ?

My LG G3 only connects to Edge network

Hello guys.
After a couple of days reading on the internet without success I decided to share my problem here.
I bought a LG g3 D850 32 gb on eBay, once I received it I was so happy enjoying the 4g LTE network, the speed was amazing.
Regrettably, one day all this happiness disappeared, now I only have Edge connection, I don't have 3g, hsdpa or 4g, I only get the awful Edge.
I have tried using my sim card on other phone and I get 3g and hsdpa (that phone does not have 4g) so the problem is on the G3.
I have to say that I have the phone with the stock rom and the only change I've done was to root it with kingroot and deleted (disable) some at&t apps. I thought this was the problem so I restored to factory defaults but the problem did not disappear.
I was thinking in to return the phone but I am in Chile so is a little hard.
I will be grateful if some one could help me with this issue.
I will be waiting for your comments
Thanks on advance

What model number/version/baseband/etc.
What's your base network and are you sure your APN settings are correct?

Hi Nick,
This is the Software info:
Android Version: 5.0.1
Baseband Version: MPSS.DI.2.0.1.c1.13-00058-M8974AAAAANPZM-1
Kernel Version: 3.4.0
Build Number: LRX21Y
Software Version: D85021r
Security Software Version: MDF v1.1 Release 3
I do not understand what the base network is. Is my cellullar provider?
The APN settings are OK. I didn't change anything.
I had all the connections and suddenly I lost 3 and 4 g and only get Edge.
I didn't change anything. I rooted the phone with KingRoot but I am not sure if the problem started in that moment.
I have made the Factory Data Reset a couple of times and the problem continues.
My Sim Card works fine in other cell phone.
Please Help!!!!

Yes, your cellular provider. What's your cellular provider and what's your APN? Is your sim from AT&T, a foreign provider or from a Chilean network? Does the APN match the SIM provider's APN?
I'm thinking that it's either an APN problem or a band switching problem (since you disabled some AT&T apps) or you just ran through your allotment of 4G data under your contract.
If you've tried your SIM very recently in a friend's phone and it works just fine, then it's probably not a data allotment problem.

I am using a chilean provider with the correct APN, the same I used from the first day when 4g were working fine and the same.
Yesterday I tried mi sim card in other cellphone and I got 4g without problem. I checked the apn and they was the same.
Now I tried with tho different ROMs, I changed the kernel and the modem and I'm still get only EDGE :crying::crying:
I do not know what to do. I think the cellphone is bad

I'm guessing that you may have disabled something when you were deleting the AT&T bloatware. You've got a D850, right?
As @trickie69r has mentioned in a previous thread, try downloading your KDZ direcly from LG's Servers using: http://csmg.lgmobile.com:9002/csmg/b...XXXXXXXXXXXXXX
(Replace XXXXXXXXXXXXXXXXX with your own IMEI, which can be found by dialing *#06* in Dialer)
Take a screenshot of your About Phone > Software Info tab before and after and see if anything changes.
Buena suerte!

Thank you Nick.
I have flashed some Roms, and the problem did not solve.
I have tried to download the stock rom but I can't download it from the link you send me. I can't find D850 stock rom.
Do you have other link to get it?

Did you try using the ROM in this thread, or just installing the AT&T apps to see if those worked?
