Hi everyone, I got a problem with my LG Optimus G Pro F240k and needs anyone who could help.
Thing is, I flashed a stock rom to go back to stock, unfortunately, my phone signal's lost. I even changed sim, still no signal.
I'm living in the Philippines and my network provider is Sun Cellular.
Thanks for those who'd help me out.

It happened just last week. Anyway, I already solved it. How about yours?

Sometimes you need to flash the modem that correspond to your device in order to get signal back to work.
I happened to me once with another phone (Samsung Galaxy S2).
A good recommendation would be backing up your efs folder before doing anything. Inside the efs folder there is some very important information about the phone, like your IMEI.

yes, it also happened and the no service started saturday evening after the typhoon Glenda left the country. I tried using my low profile phone and it has signal. but things went back to normal now.

At first I tried flashing my baseband. but it was no use. Then some technician here told me that the last trick was to flash an e980 kdz file then afterwhich, I flashed back my f240k kdz. that's it. All signals are back now. Never had a problem since.

[Q] Generic IMEI after OTA 4.3 upgrade

Hello to everyone, I was wondering if anyone can help with this. I have a Galaxy Note 2 branded by an Italian company (3hg Italia). It recently received its update to Android 4.3 (update N7100XXUEML2). It was the official update OTA, the phone is not rooted and it had the stock ROM on it. The update somehow messed up my IMEI making it appear as the generic 0049 forcing me on "Emergency calls only" mode. I already tried flashing the same ROM with Odin and repeating the update with KIES, but while the updates always results successful the IMEI remains 0049. I never made a backup of the EFS folder for this phone since I haven't rooted it or flashed any different ROM on it yet. There is any chance that the phone made an automatic backup? I live in the States right now and Samsung tells me I need to ship it back to Italy to have it fixed, but that costs a lot and would take forever, and I would much prefer try to solve the problem locally. Any suggestions would be greatly appreciated, if not for any fix that I can try myself, at least some place on the West Coast that can fix the problem!
Thank you!
Lorenzo
Oh I forgot to add that because of Hardware problems I recently sent my phone to Samsung and they replaced the motherboard, which fixed the problem I was having. I don't know if that could be related!

I'm afraid that fix works just if you have your actual IMEI, I instead have the generic IMEI that starts with 0049. But I will check it out! Thanks!

Then you should simply flash another modem from here : http://forum.xda-developers.com/showthread.php?t=2044937 ... flash a custom recovery first.

So I found someone nice enough to give me a hand with this situation, but still no luck yet! Here what they say:
At first glance, the EFS data on the phone was corrupt. I re-generated
that data and restored it to the phone without success.
The GSM radio itself is operational, and the firmware for it is
installed and functional. diagnostic data flows to the towers and back
to the phone but it's not reading the IMEI from the copy of
nv_data.bin contained within EFS. I've re-generated and installed
those files as well, again with no luck.
I rolled the device back to it's original factory firmware and radio
baseband, then ran through the update for the radio baseband, which
also regenerates the contents of EFS, and still no luck.
Given the situation, anyone have other suggestions?

LG G3 Cannot connect to network after KDZ Flash

Hi,
After using the KDZ method, my LG G3 cannot connect to the network. I get the "service disabled", "no Service" and sometimes it connects to the operator for some seconds. It is important to say that before the flash, the phone was working fine, and connected normally to the network.
Troubleshoot already done:
1 - Firstly, I flashed using the D85520B_00.Kdz file.
2 - When I realized that the error, I thought this might be a version problem, so I downloaded D85510e_00.kdz version and re-flashed downgrading to 4.4.2. However problem remained.
As a comment, I also noticed that it changed from version D855 to D855V.
What should I do?
Either its a problem with the modem or you lost your efs partition
What does it say under IMEI? Does it still show your phone's IMEI

Still, that sounds exactly like a corrupted-EFS problem. But with corrupted EFS, in most cases, IMEI is reset to 0... If you have a backup, try to restore it.
If no or if it still doesn't work, try to flash an other KDZ (with modem inside) or just a standalone modem.
Also, check APN and that kind of software things

Hi.
the IMEI SV is set to 00. The IMEI is XXXXXXX... If I go to Network, it will be searching for service. Actually, I can see the network, but I cannot connect to it. I get the message "Unable to Connect to Network". I have already tried 3 kdz versions, without any success.
Just so we're clear your using CSE flash with the kdz right?

Hi did you find the solution...? If yes plz let me know I have the exact same problem...
I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!
Hi
I suggest you download the LG phone from app and this will give you which Stock Rom is for your phone. Then you need to search For it and install. I have a D855 Taiwan version and that is what i did and now on Stock D85520W.
Hope this helps.

I know it so bad I just want to fix so what should I do >??? Should I have to flash stock firmware ?? or what Please help me
You can try flashing original KDZ for your variant.
You are now in the realms of hard bricking your phone, proceed with extreme caution.
I suggest flashing KDZ for your phone and hope that your phone is recovered.
if the problem still persists, in my previous experience with galaxy S3, if the efs partition is broken, IMEI will be gone and network is unusable except for SOS call. this is irreversible without the partition backup.

Under warranty probably. If it arrives at their repair shop mysteriously bricked somehow, but with no hardware damage, they have the ability to reflash/replace the necessary parts and get it back to you.

D850 wrong rom

Hi everyone in this incredible web!
I bought the LG G3 D850 AT&T kitkat (T-mobile logo on the back), and flashed the D855V Marshmallow with LGUP.
I get this message "current version is not available for user. Can't find matched cust for NT-code mcc/mnc [310410] subset [FF]"
Since then the SIM card will get no signal. I've tried every possible thing to flash any rom that will work.
Anybody can help me, please??
Many thanks.
J.H.M.
I'd restore to stock KitKat and start over if I were you.

Have you confirmed if the device is truly ATT or T-Mobile? You should be able to double check under the battery. Once you know that, download the correct tot file, throw it in download mode and restore using the tot file.
Well dear. What my friends are sying is true you should flash a stock. Firmwere via downloading mode and it will be. Ok. If it still not working than. Go to mobile softweres shop the. Can make it good like u want

Help with ZERO networks!! Before I burn this THING!!

Okay story so far, got Zuk Z2 from BG China to replace Mi5 that had a tumble
After a couple of weeks I decided to flash Custom Rom (LinageOS *UNOFFICIAL), seemed fine then I lost Network totally on both SIMS.... Zero bars! I've tried all sorts of ROMS and flashes of Baseband firmwares but to no avail. Now I think I've confused myself.
So if anyone has any advice before I cast this device from a high roof it would be most appreciated.
Thank you :good:
You flashed already different basebands via fastboot, erased modem after that?
Tried flash stock ZUI via qfil?
After all no network? IMEI's are there?

When it first gave up network I checked IMEI and it seemed to have duplicated them for both sim but after I QFIL back to ZUI 2.5 they returned perfectly... I've gone through the whole erase modemst process but still FUBAR....
Even stripped the device down to bits and checked the internal connections.
He strange part is I get the emergency only msg on sim so guessing the network is recognised but the signal is -90 dBm at best, getting to as bad as -130 dBm.
Even considering writing the IMEI from old bust Mi5 to handset to see if this would help...

Yeah I guess every other android and iOS device I've either rooted or jail broke was pure luck and the huge amount of posts on many sites including Lenovo regarding this baseband problem are all very similar 'lab rat' experiments.

I had a dabble with QCN and managed to replace corrupt IMEI's but still didn't help. Can't be sure the BASEBAND was correct though.. I'm yet to try a full FACTORY DEFAULT configuration as suggested but will be this week.
Been suggested the IMEI may be blocked for some reason but seems unrealistic as it was working prior to FLASH.
