So I was running on stock, rooted rom. Everything was working well. But I wanted to get rid of the Korean apps.
soI flashed a stock based rom found here:
http://forum.xda-developers.com/showthread.php?t=2462453
Flashing was successful, but my phone no longer reads my sim.
So I went back to stock by following the guide here:
http://forum.xda-developers.com/showthread.php?t=2432476
Again it was successful but my phone does not read my sim anymore.
I tried different working sim, same problem
Tried reflashing. same thing.
Also I noticed it does not show my phone IMEI under phone identity.
Can anyone help me how to fix this, or point me to a guide I could follow?

Any luck in fixing this problem? I'm having the same issue after trying to install Update v5 with Knock On. I tried installing the basebands but most of them will give Service Disabled with Unknown IMEI. But the E988_HK_Final baseband shows the IMEI and Phone Number but has No Service though or very weak signal. Also, it seems like the QRemote also stops working in my case.

Please flash LG F240L Rom (KDZ File), It will work,

It looks like your EFS partition is corrupted. Did you back it up through Freegee before installing the custom ROM?

I had this happen to me with an e980 out of the box. I ordered it online, and was in the process of adding my apps and customization without ever rooting it or doing anything outside of warranty and all of a sudden I got "Insert a valid sim card". Just happened out of the blue and I only had that phone for 12 hours. It is some rare hardware issue that AT&T couldn't figure out either. I believe it is the sim slot that is malfunctioning because in mine it wouldn't recognize any sim card but my sim cards worked in other phones.
If you have a contract phone, undo root, flash the stock rom, factory reset and call tech support. They replaced mine for free because it was determined to be a hardware issue. Good luck.:silly:

[Q] Need Help /Trouble/Advice/Suggestion

Problem
I Brought A new Gpro on 21st Dec E988 India, it worked fine for a week , Then I rooted it using the Sticky thread By ballshanglow.
Next day I see my 2G n/w signals are gone totally , I switch to 3G/WCDMA and Bam it works both voice data , but switching back to 2G still doesnt work.
What i tried
Factory reset using Power + Vol Down button : Problem still persists
Flashed original KDZ E988 10e India with Flash Tool : Problem Still persists
Flashed stick rom via Lg support tool : Problem Still Perists , still only 3G no 2G
Then
I thought Maybe it's a BB issue , but doesnt flashing stock KDZ as i did before restore the original BB ?
Anyways
1) I rooted my phone using the same method as above
2) Installed Latest Freegee
3) Installed CWM from there
4) Flashed a certain E988 10a(India) BB and Rebooted from CWM
Bam a bootloop , Now what should I do , I am stuck with no 2G network at all?
Request/Advice/ Suggestion
There is an awesome Thread which keeps track of all Stock KDZ
there should be a similar thread that keeps track of all latest BB too , Currently I see individual Devs have BB for somemodels or just a few BB in their own cloud and all of them are scattered .I would request some Senior Member here to create one thread as sticky so as to help every newbie.
Many people on different models of Gpro are having problems with CWM installed with freegee , some have touch problems on TWRP , i had them too , it would be good if the sticky threads could recommend which one to use.
Sticky threads should also explain the what all models our phone has , Concept of Recovery , BB , Modem , firmware as only people who have flashed a rom earlier would be aware of these terms , for others it might be rocket science
Personal Help
1) after a lot of searching I found E988 10a BB (India) , Does anyone know a newer version ?
2) Since CWM from freegee gave me Bootloop , can someone tell me which Recovery should i use CWM,TWRP or Philz touch and if cwm or Twrp how to install them aside from freegee?
Thanks Everyone who has took the pains of reading my Post and also to the one who try to help.

and converted it to e975 and installed ind fw and flashed f180L baseband and also unlocked edge all was ok till here. than i rooted it tried to install

pressed power here where it stuck with security boot loop so i again flashed the f180L orig fw and here when problem started as there was
NO SIGNAL. now i read many threads here in xda also tried many firmwares also installed ics 4.0.4 no signal but when i installed a 18mb update
for ics 4.0.4 using built in updater full signal came back but when i switched off the phone and turn it on again there,s no signal also installed

open this file https://mega.co.nz/#!L54n3TjD!GF5xgTzYX1BslEzVMU9QHkQ6SKZsAOZIMEBtNR2udCw
Extract folder "BaseBandF180L_OK" (there was no problem in WIN7 with this procedure) and then:
- connect the phone to USB in MTP MODE and copy "BASEBAND.IMG" to SDCARD ROOT
- check "DEVICE MANAGER-ADB INTERFACE-LG "something"" (it should be OK - only if hou have installed drivers in WinXPMode and you are connecting the phone in WIN7 then you have to install those 3 files from point 2 and 3 above)
- so if you see ADB Interface for LG, you copied the IMG file to SDCARD and your phones ROOT is OK then ...
- just run "FLASH_BASEBAND.BAT" and wait for restart
- now you should be asked for PIN (if you use it ) and you should get a signal (greditsfor all this i going To Happy_Alien)not me

restore efs(i didnot do that but only flash baseband) and then flash the baseband.be sure that your phone is rooted ,mtp mode,usb debagging and uknown sourses enabled.try to flash jelly bean not ics.

Flashing E980H on E988

The IMEI on my phone (E988 Taiwan) has disappeared. However, on this thread (http://forum.xda-developers.com/showthread.php?t=2379532), quite a few people have successfully restored their IMEI by flashing the E980H rom and then the rom of their model. However, everyone who has been successful has owned a Korean model (F240x) not an international model (E98x).
Has anyone successfully flashed the E980H rom on the E988? Some people have said that it might not work and that the phone will be completely dead (no download mode). I have noticed that the firmware for the E980H is v10A and the firmware for my E988 is v10B. Could this cause a problem? All I care about is the phone being able to boot up, not really much else.
Thanks

I am not sure if i am right or not but so far i know by going through all the forums is if you flash E980H on E988 you need to flash the specific baseband of E988 to get all the features working ie speakers, gps etc.
Senior members please do correct me if i am wrong.

I don't care if some of the features don't work. I just want to make sure that it won't brick my phone when I flash it and that I will then be able to flash the E988 kdz afterwards as this is what some people have said recovers your IMEI.

e980H Factory Image TOT and DLL file
Hey guys sort of a side note.... Do you have access to the e980H .tot and .dll file to flash onto my ATT e980?? Can't get KZD files to work

LG-G3 D851 - 4G stopped working on Android 7/8/9.

Dear all,
I got a strange situation and I've tried several options already, but I'm lost.
My LG G3 D851 (T-Mobile) is currently running on Lineoage OS 8.1 and my 4G is not working.
Even though I selected 4G preferred. Highest what I get is H+.
I've found a modem file, but that screwed up my 4G and 3G completely.
It doesnt matter which custom rom I select it will not allow me to work with 4G.
If I go back to the original Android 6 Rom I got 4G.
Who got an idea to get this fixed?

Is your IMEI still There ? Does your Phone Show Up at qpst? You did Not Read
anything i grüess so you probably havent Backes Up your efs? Ist there No Connection at all? Flashing Roms will Not fix your problem. But you should Go to Marshmallow Stock For now.
Custom Roms only Work with 21c and lower maybe you Just flashed The Wrong Modem. Google For The XDA LG G3 Modem thread

My IMEI is still tere.
Dont know what you mean with QPST.
I've got backups and I can go back to any state, but I dont know what I should even consider check the EFS?
I'll check the Modem thread.
Maybe I can find a solution in there.

The 21C thing is incorrect. Each variant of the G3 has their own set of modems. There is no 21C for the D851.
If memory serves we had 10 series (KitKat), 20 series (Lollipop), and 30 (Marshmallow). I'm currently using 30D modem from last time I had a factory stock installed. I get 4G/LTE on all of the installed ROMs (KK, LP, MM, N, O). Even when I was on 20G they were all good, though I didn't have Oreo at the time.
@Mr-Dutch, I have a small collection of D851 modems up on Mega. Since your last stock was Marshmallow I figure the ones to try, if you elect to do so, is 30D or 30E.

LG G3 D851, Mahdi v2.9 ROM (4.4.4), microG (NoGApps), MultiROM, XDA Legacy

Yeah my Bad that was for The 855. And there IT says in The Post that IT only works Up to 21c but Not sure If thats still a Thing.
So have you tried flashing a Modem? And does IT Work now?
