hey fellow members,
k, so I've been having this issue where there's no signal and the baseband is unknown. This has been happening ever since I flashed KitKat and usually after I reboot the phone, the signal/baseband would pop up after about an hour or if I'm travelling around town.
When I did receive signal, there was no audio during calls so I decided to flash the kitkat factory image hoping it would solve all these issues but now the signal never shows up and the baseband is still unknown. Then I flashed jellybean 4.2 factory image and the problem doesn't exist, I receive signal immediately and audio during call worked so I ruled out a possible hardware issue.
I've also read through the other dozen of threads with similar problems but none of those solutions seem to solve the issue.
I have no clue what's going on and any help would be great

Sounds like a radio issue. Try flashing the latest radio, which is .98 I do believe.

I've done that already but still nothing
k so I got signal finally after a day of waiting but there's no sound during calls again. Any ideas?
anyone? I've been searching for a solution but haven't got anything.
Does your phone have a valid imei? I'm just guessing here as I've seen posts from N4 owners that lost their imei during a flash or update process.

Very strange. Maybe flash back to completely stock 4.4.2 or flash a custom rom that includes the latest radio and bootloader?

So why not (for the meantime) go back to 4.3 or 4.2? Get it to work, then let us know the radio it is using and go from there.

Well i was trying to to flash a new rom on my D802 and accidentaly i deleted everything... a full wipe from phone menu ( not recovery )
Since there was absolutely nothing on the hard drive anymore ( i assume) Phils TWM coudnt find any folders .. i had to push roms to the phone through adb now the problem is that no matter what rom i install i get no connectivity/no service .. cant recieve any calls or use data... only wifi...
I tried re flashing...
Stock rom
Paranoid rom
G flex rom
Stock kernal and peak 5.2 kernal
Nothing has worked? How do i restore connectivity to my phone? Thanks
You have a problem.. Your EFS folder was probably wiped
I guess you could reflash your kdz and bring it into the service centre?

I bought this phone through Kogan shipped from hongkong... This will take weeks, perhaps months... I am not even good with reverting phone back to stock as if never happened...
Is there any other way for me to fix it myself?
Anyone.?
there are plenty of guides on xda on how to revert to stock. search these forums and read carefully. you will be back up in no time. there is also a thread on stock modems also. give it a whirl

On another thread someone suggested this :
NomadCF said:
Honestly, you'd need some one to send you their EFS backup (who's on the same carrier and model). Then you'd need to extract it. Then edit it to replace their data with yours.
But I don't think your going to find anyone willing to do that. As it's a HUGE risk to them. So I think your only bet it to to a warranty or repair 'call' with lg if not your carrier.

Warranty service?
Yeah, if you wipe your EFS, flashing back to stock wont help. The EFS partition contains files individual to each device, you will probably have to return it for repair man D:
I've had the same problem too, my SIM card doesn't seem to be reading on my phone either; and it definitely a functional sim.

I'm sorry, xda mail somehow has been going to my spam folder.
Anyway I am not familiar with this issue, but perhaps you can restore your stock rom via flashtool, then call LG and tell them that you don't know why this happened Oh and modems are distinct from EFS I think (at least that's my understanding)
Your main problem will be the shipping though
I found this thread for the lg optimus G though - http://forum.xda-developers.com/showthread.php?t=2161498. Perhaps try PM-ing autoprime?
Same Problem
I also am in this EXACT same position. Still havent found a resolution quite yet. I am in correspondence with Shellnut the guy who actually wrote the freegee app that uses loki to flash cwm and twrp. He said that only cdma phones need efs, that the gsm phones didnt need it. This was new information to me. I haven't heard back from him quite yet as he informed me my phone wasnt bricked and that they would help me get back up and running. I know he is extremely busy. I have also been hearing that you can possibly use lg qpst to manually write your imei, looking into this now.
I would love to not have to take the risk of sending it in. Would love to just fix it.
i'm in the exact same position right now. Hunting the threads for a fix. I will be going back to Hong kong in 2 weeks time for 2 days, not sure if thats sufficient time for LG to get it fixed.
Hopefully we can find a solution soon!

Hi man. People keeps telling you to install new modem, kernel etc...but i think you have corrupted EFS folder.
I hope you backup your EFS folder before flashing ANY rom because, otherwise you will have to go to some repair shop.
Well, I don't understand a lot, but I think you could check if you didn't lost your IMEI. Go on Settings > About Device > Status and check if your IMEI still there.
If it is, I don't know what could be. You could try flash another modem or restore a backup (if you have one) with PhilZ Touch but if it isn't, that means you lost your IMEI. I remember I read about that somewhere, that there is a risk of losing IMEI when you flash a lot of ROMs.
If you have backup from your IMEI, just restore it. If you don't, I don't know what you could do, but I guess you could still do something.
One more thing: Wi-Fi works?
Like I said, I don't understand a lot, so everything I just said may be very stupid. Or not. Sorry for bad english.

When I turn my phone on it goes into boot loop. I tried accessing TWRP but it's not good either, it would just show the startup screen and nothing will happen. I don't know how this happened because my phone was working perfectly last night before I slept. I didn't charge my phone so when I woke up the battery was drained. So I plugged in my charger and turn it on, it'll just go into boot loop just like what I said earlier. Please help. I have read that I should flash stock through Odin, but where can I find it? Please help. Thanks!

Thanks, I actually know that I have to go to that site to download the firmware, I just needed some confirmation haha! But this here is my real (stupid-ish) question, is it possible to recover/access my data? Will it be lost after flashing?
When my device was bricked a bit times... I flashed the firmware and all my data wasn't lost it just changed the system and did not delete any data... But make sure u only flash the firmware version that was present before u bricked your device....
MOST of the times it doesn't delete any data☺

Hello, my G4 Plus reads IMEI 0 when *#06# in ROM, but I can read the correct IMEI from fastboot getvar imei and can see my correct IMEI in /proc/config/imei. Any help to restore my IMEI is appreciated, I will be happy to provide and test any information as needed.
Also, I can connect to my carrier, but I cannot use voice, data, or SMS. Sometimes it drops to no service.
Would anybody happen to know how to enable RNDIS + DM + MODEM mode on the G4?

Is your bootloader unlocked? If so I'd go to TWRP and flash the stock 93-14 N backup that's floating around somewhere on XDA.
Also, make sure to flash the radio and fastboot corresponding to your stock ROM version.

Gesendet von meinem Moto G (4) mit Tapatalk
I think the IMEI isn't erased. I had the same issue last month. There are different types of firmware(custom roms are based on them too) and they doesn't notice the IMEI If you flash the wrong one. So I would recommend to flash the right and if you do not know the right, try every (I suggest to test the Indian one first. In most cases it is the solution).

That's not good idea to flash all available firmware. It can be old firmware and flashing old firmware (downgrade) can damage lots of things on your device.
First tell us which device you have and if your your phone is g4plus and not changed to normal g4. FingerPrint working correctly ?
Try "fastboot getvar all" command check if it shows your IMEI somewhere, and post result here. ( if it shows IMEI, then tell us and remove it and post.)

In my case I flashed all firmware included in android 6 (it's stock) from a custom android 7 build. I know it's an old thread but I'm still open to suggestions and hoping to fix this.
To make more sense, I downgraded from 7 to 6.
