if i understand correctly, i can flash any custom rom on the f180 as long as i flash the korean baseband and backup efs, right?

any rom for the e975 i mean.
[LG Optimus G (International)] JiroPrinz8:
Just wanted to thank you bro, [MENTION=4591006]davevinci[/MENTION] i succesfully convrted my f180L to e975 v10D woth your tutorial. I also had to factory reset as i was stuck in scanning media files, after that freegeed, flashed f180l modem and im good. I didn't lose IMEI so I didn't have to restore EFS, but i did back it up just to be safe.

I have everything working including data with H speeds. THANKS!!
[LG Optimus G (International)] Ganz.Conrad:
Hi, I converted my F180K (20N) to E975 (europe common 10D), but I have problem with WiFi. I Can''t connect to WiFi - "waiting IP" all the time. Search mode works, "password type" works, but no connection.

I tried to flash different basebands (my own- backed up from stock rom 20N, one from this thread, and other downloaded from forum). I did it with CWM (install zip after bootloader unlock with FreeGee)

and with adb:

and I think, that baseband has nothing to do with WiFi...

so: how to fix WiFi?

How?

successfully flashed e97510a ROM

flashed F180K modem

restored my EFS

still no signal for my Globe SIM card.
[LG Optimus G (International)] AhsonAli:
While on Stock Korean Jellybean 4.1.2, I did a hard factory reset

then without configuring phone turned it off and put it into download mode.

Flashed E97510H (open euro ROM) with my sim card inside the phone

Rooted/ Freegeed and installed CWM 6.0.4.6

Flashed f180k modem ( https://mega.co.nz/#!AEAQBbrZ!Twfb6iTXj51rzI5ayR2vMCN4ouAWdyh0b23IkbBRJXM ) it was not through cwm.

downloaded the file unziped it unabled USB debugging, attached in charging only mode, ran "modem-flash.bat" now changed the mode to MTP granted superuser permission that prompted on screen and followed the instruction on pc.

that fixed it for me I didn't had to restore efs

after that I flashed cm11 n pa-gapps and using it ATM.

you should flash this modem only if you are f180"K"
[LG Optimus G (International)] hpesojames:
thanks for the suggestion...i'll give this a shot later.
[LG Optimus G (International)] AhsonAli:
these are the links for basebands of all three versions

F180K ( https://mega.co.nz/#!AEAQBbrZ!Twfb6iTXj51rzI5ayR2vMCN4ouAWdyh0b23IkbBRJXM )

F180L ( https://mega.co.nz/#!4RQyXRwC!cvFoqkX4p_nzgvm8zjmuP1wbV0kikdeWo5EbO_x0-rc )

Goodluck. :)
[LG Optimus G (International)] hpesojames:
thanks mate...I'll keep this thread posted of my success with luck of course! :angel:
[LG Optimus G (International)] davevinci:
Try those basebands... Efs is also related to baseband... What's best is ur efs should match with the baseband... Example ur on latest korean firmware and made a backup of efs in that firmware then after conversion u should also flash the baseband of that firmware to avoid signal issues... That's why it's better to backup ur own modem
[LG Optimus G (International)] hpesojames:
SIM card still invalid mate. :(
[LG Optimus G (International)] AhsonAli:
I couldn't find any guide to back up my phone's modem

so I only backed up efs as per your guide...

can you tell me how to backup modem?

---------- Post added at 05:54 PM ---------- Previous post was at 05:51 PM ----------

mine never said invalid bro

my network was being identified but no service.

try flashing that hustonn file in cwm, after clearing data/cache/dalvik
[LG Optimus G (International)] hpesojames:
i did everything as stated in the 2nd page of this thread. except for the manual backing up of EFS...but did manual restoration of EFS though.

I guess I will have to revert first to F180K firmware and try my luck again. :(
[LG Optimus G (International)] AhsonAli:
Don't worry

I've messed up my phone in every way possible, still got it working...

and first step is always flashing stock ROM.

somewhere in these forums there's a link for downloading official firmware for your phone by inserting your IMEI at the end of that web address, that should download the correct and latest available firmware for your phone.

I'll post back if I find it.
[LG Optimus G (International)] hpesojames:
Yes i know theres still life left as long as xda is here hehehe!

Im actually downloading my stock original firmware now.

But still keep us posted of the link if you can. TIA!
[LG Optimus G (International)] AhsonAli:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=YOURIMEI

replace "YOURIMEI" with actual numerical imei without spaces hit enter and this kind of page should load

copy that highlighted link shown in screenshot and paste it in your downloader.

Once downloaded use this guide to flash stock ROM

Mobile Network up & running! FINALLY!

after flashing different e975 roms of different countries...i was able to get mobile network running using e97510f HK firmware BUT flashing both (1) F180K baseband and (2) F180L baseband...after that, voila! phone asked me if i would like to enable mobile data. then signal is finally up for my phone. didn't restored EFS though.

UPDATE:

I also tried flashing firmwares e97510f Philippines fw & e97510h Europe Open fw then flashing F180K & F180L basebands...mobile network still worked.

but 10h euro open fw does not show LTE setting using *#*#4636#*#* codes. even in the Mobile Networks settings menu.
[LG Optimus G (International)] AhsonAli:
Glad to hear that your phone is working again, could it be that you are mistaken and your model is f180l?

what does it says at the back?

U+LTE is f180l

4G LTE is f180s

and

O is f180k
[LG Optimus G (International)] hpesojames:
its an O as in Olleh bro...so its an F180K.

these were the ones i used when i converted to e975.
[LG Optimus G (International)] nitski:
For those having difficulties getting no network signal after flashing E975 ROMs specifically coming from F180k, I would suggest that you backup first your original modem and efs files of your original F180k ROM.

I have a F180k unit with 20o firmware. After following all instructions on different sites including the one posted here, my phone still have no signal. So I reflashed the original korean firmware and backed up the modem and efs files. After flashing the E975 firmware, Euro open 10H, I restored the modem and my phone started to receive network signals.
[LG Optimus G (International)] hpesojames:
may i know how did you backed up your original F180K modem? thanks!
[LG Optimus G (International)] AhsonAli:
Hi guys,

I have problem whenever I flash aosp based custom ROM on my lgog f180k I get no service. (on lock screen it detects my network and says "No Service" and aside that displays my carrier name) antenna is catching network but not providing service.

And flashing back to stock f180k ROM, disables all network services (like its locked).

Only ROMs that work are stock E975 or CM based ROMs for E975, all the ROMs for geehrc gives "No Service" error.

But CM based ROMs crash on my phone.

So following the forum I tried everything

From flashing different modems for f180k,l and s (both via recovery and ADB)

to inserting other carrier sim

Restoring efs (BTW I never had IMEI null issue)

Editing build.prop as directed by many.

Setting to WCDMA preffered

Reset

Wipe

Factory reset

Manually searched for network, it keeps searching forever.

Anymore suggestion before I revert back to Stock E975

And yeah that Corporate lock check code shows everything is permanently locked.
[LG Optimus G (International)] hpesojames:
im using vanir with mobile network up & running.

my phone is from F180K, kdz E975, flashed F180L baseband, flashed vanir.
[LG Optimus G (International)] Damien11:
1. go to recovery

2. on adb shell type

su

for root

To backup

dd if=/dev/block/platform/msm_sdcc.1/by-name/modem of=/sdcard/modem.img

This creates a file named modem.img on your /sdcard, copy it to a safe location like cloud storage and your pc

To restore

dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem

Place backup modem.img on /sdcard
[LG Optimus G (International)] hpesojames:
ic...i was thinking maybe there are other ways or other files aside from modem.img. thanks btw!
[LG Optimus G (International)] nitski:
I attached a batch file for backing up and restoring both the EFS and modem of F180k. You may try it and give us a feedback if it works for you.

Hello all F180 k

i accidentaly deleted font files in system/media and phone got bricked

i some how managed to get my phone out of brick and flashed kdz but problem was INVALID SIM CARD

i tried to flash baseband for F180K but no luck

i flashed stock KDZ for F180K but again no signals(i dint flash modem after flashing stock kdz)

i flashed open euro kdz E97510F honkong

flashed F180 k modem=invalid sim card error

flashed F180L modem=invalid sim card error

flashed F180k and F180L modems back to back=invalid sim card error

now ive unlocked bootloader installed freegee and unlocked bootloader and installed cwm recovery.will flashing a custom rom do the job .

P.S : i dint make any efs backup because i was bricked.

i tried possible methods like hard reset,wcdma preffered,gsm preffered(1 IMPORTANT THING is once i search for networks manually it shows

just one available network Paktel gsm(it is in my country)but no other network.

for reference i am attaching SS
[LG Optimus G (International)] nitski:
i assume that you have the F180k model since you posted your question here. First, did you flash the original KDZ file to your unit that came with it? I asked because once I flashed an older KDZ to my F180k aside from the original one that came with it. result was no signal but can detect my local telco. so i downloaded the firmware that was originally installed to my unit and flashed it and the phone started to receive signals.

i think u have messed up the efs partition, i m in a similar situation like u r, i have f180L and no signal problem. i showed it to hardware expert

and he is saying that it will take one day to repair and he will do it through test point and jtag and he need to open the mobile phone too.
[LG Optimus G (International)] Ahmed Xperia p:
I called a software guy and explained him the situation, he told me most probably it's locked now and need to be relocked again . I didn't understand tha because i think all these phones are unlocked .

I think only option left now is to use it as a wifi multimedia device since n solution seems to work for me .:(

[LG Optimus G (International)] AhsonAli:
if you are still on this firmware, go to playstore and download app called root checker....

see if your root is properly patched....

if it is then attach ur phone to computer "Charging Only" mode

run flash-modem, and keep an eye on ur phone screen and allow su permission when prompted, also follow steps on computer... after cmd exits, detach your phone and restart it....

---------- Post added at 01:43 PM ---------- Previous post was at 01:36 PM ----------

like I said, my phone is locked (probaby because I unlocked bootloader to install custom roms and then kdz back to stock via lg support tool, which made it locked)

and since then I can not access network on f180k stock firmware "Service Disabled"

what I did to fix it...

1. flashed e97510h (open euro)

2. factory reset

3. rooted and updated supersu

4. flashed f180k modem

5. restart... and signal was up

now i have unlocked bootloader (via freegee), installed twrp... and I can flash any custom rom for e975 on my phone (edit build.prop, in zip before flashing)...

currently using houstonn's AOSP 4.4 kitkat without any issues....

---------- Post added at 01:48 PM ---------- Previous post was at 01:43 PM ----------

if your imei and mac address is visible and u can access root, 1st thing u should do before messing around anything is back up ur efs...

here's a guide somewhere in forums on how to do that....
[LG Optimus G (International)] Ahmed Xperia p:

telephony.lteOnGsmDevice=1

ro.telephony.default_network=8

ro.ril.def.preferred.network=8

and remove any other similar line from that build.prop i.e. "telephony.lteongsmdevice=0" etc

save it and now go to settings and factory reset your phone...

once booted

go to settings > more > mobile network and select these options

reboot again...

and see if signal is up...
