. I flashed the KZ file with lg update software as explained in the XDA thread but I could not get the process to work right. My phone kept disconnecting at 28% and it would not turn on no matter what I did. It would only make a short vibrate as if it was turning on, and the computer would notice it but only for a short time. And never once did a light on the screen, or LG logo, or anything at all ever appear.
I figured I had really screwed it up, but when I plugged it into the wall it booted up perfectly. All my data was in tact and the rom i had flashed through cwm was still there, not the kdz file that I flashed with the lg software.. I noticed that my sim card did not come up as being in the phone at all. I looked in system setting status and noticed that all info related to my imei said unknown. I opened up the mfg app (277634#*# from the phone app).. Under "version info" then "factory version" my phone now says xmm6260.. It always used to say p925..etc... Even after flashing the zip to debrand from at&t this never changed from p925 even when every other aspect of my phone has.. I was hoping maybe once I put in an activated sim card everything would be fine and my phone would be unlocked which is why i flashed through lg software.. But seeing as how other people are having this similar issue and their phones not seeing the sim card, well im looking for some advice.. Should I try and re flash kdz file through lg software again? if i do, im going to do it on my XP computer this time, not Windows 7..
Just wanted to add that I did try wiping data and cache from cm and no dice.. Root and CMW work fine but no matter what I do, if my phone is turned off, i cannot boot up or boot to cwm or boot at all unless i plug the phone into a wall carger and then once its on it stays on and i can unlug.. SORRY ABOUT THE LONG POST, THANKS IN ADVANCE FOR ANY HELP..
I would reflash CWR first and foremost, then try to flash back to stock.
No IMEI/GSM Radio
Hi, were you able to fix your problem? If so, could you please give me a hand, I have same problem.
Im attaching a couple of screen shots, one where you can see that IMEI is not shown and other is where you see the phone number thats on the SIM but has a sign like if no SIM were inserted.
Using the KDZ detects the IMEI, but after flashing it doesnt show up on phone.
Thanks
Took my phone to a cellphone shop and they fixed it. Everything is back to stock and working normal.
Hi ive got the same problem, did you fix it?
Yes, my phone is working perfect at stock. Im going to wait for GB ir ICS with a working 850MHz baseband.
Couple days ago, got notification of the update, wasn't on wi fi so waited until i got home to download it when it was already downloaded started the install but phone was under 25% so waited until it was ready , the phone had like 26% so started with install again this time phone rebooted but when was back on it said there was an error installing the update, phone still on:
Version 5.0
kernel 3.4.42 Sun Nov 9 2014
System version 22.11.6
Build Number LXB22.39-6
If im not mistaken , everthing still the same , now when i check for updates it says phone is already up to date , tried with Motorola device manager and it says the same . already tried to find a zip of the update but didnt find it
I have unlocker bootloader but still have the stock recovery
Is there a way i can update my phone? :/
Which variant? Check the box or take off the back cover. It should start with XT106, the last number will determine the variant.
sorry for taking so long to answer , it is xt1063 variant
Appreaciate your help!
Hello guys,
Short version:
My O4X suddenly lost signal and IMEI, look likes hardware problem. But when I reflash with V20A kdz, it works then after few restarts, It happens again.
Any help will be appreciated. Thanks in advance.
Detailed version:
- I was on CM11 nightly (20140923) for some time, it was smooth and no problem but then suddenly lost imei and signal.
- Tried to flash and wipe the latest nightly without luck
- decided to try the V20A kdz and it works again for few restarts (root and stuffs)
- Tried kdz without doing anything, just restart. After 3 restarts, lost IMEI again.
Thank you for your time and thank you in advance.
Also the friends here have similar problem but mine is still flashable... not sure for how long

I have your s problem and dont know what i will do. If you can. Please help me/
i have the same problem with my p880
I had the same problem...
In my case, as far as i can tell is hardware related.
The connection (imei and baseband) returns only if i use brute force, and start to press the phone very hard near the edges, near the the sim. .But they disappear if i turn off or reset the phone...

Is hard to take pictures because this is not a tutorial, i press different parts every time i lost my imei, until it works. What i do is pressing really hard (even bending a little the phone) everything above the battery, especially the sim card holder. Sometimes take 5, 6 , 7 attempts until the signal returns. When the phone turns on wait a little, because takes a few minutes until the signal returns.
I have kind of the same problem, but with slight differences: if I restart the phone, most times than not I get the signal back (at least for a few more hours) and using Zaiben's RC17 ROM it manages to get the signal back by itself after a while, no reboot needed. What I've found to be a "hack/solution" for this problem is to use the app Tasker to change network mode from 3G to 2G when the screen turns off. It appears than while in 2G this problem doesn't present itself...
@sergiohinniger apparently your brute-force method kinda works for me as well.
My phone started losing IMEI and baseband version after I replaced the audio jack and "small" PCB (the one with USB - now I'm back with original one). I then re-chcecked all connectors and coaxial cable, but the issue persists.
I think it works after few reboots with pressure on the back, so I believe that most likely it's caused by some bad cennectors. I have no idea though what to do with that Help, anyone?
It's true, with Zaiben or any stock roms the signal returns far more easily and sometimes resists the reboot. But now i have a new problem, the mac address, even when the signal returns, stay 00:00:00:00:00:00. I can only fix with a mac spoof app. This problem doesn't happen when i use custom roms, but the 3g signal is harder the return.
Some news, bad news
I have asked some repairers and here is their answer:
It's baseband file problem, if you have original Nandroid backup then it might help otherwise you can say bye bye to it

basically, the baseband/IMEI file is damaged due to flashing rom, if you dont have origianl file, there is noway to save it
Sorry for bring back a dead post, I think it's a good infomation for people
Need Help "LOST IMEI and Baseband Unkonwn"
I was using Euporia 5.0.1 on LG 4x
I received update notification and I downloaded Update.zip ( which included to 5.1)
By mistake i flashed the zip directly from CWM ( without Formatting any partition )
after restarting there was no IMEI
Following things I have tried
1) Trying to flash Original V20C KDZ. via LG Flash Tool. ( I think it checks for IMEI , and that's why stuck in between)
2) Use LG Software Update tool. ( also can't progress with IMEI)
3) Flashed Original V20c Flashable zip from CWM (But it didn't restored my IMEI)
4) Contacted LG Service Center, and They say You need to change whole Motherboard. ( I was Shocked to know that )
:crying:
If anybody went to same problem. and resolved .
Please Guide me.

A repairer told me that some rom might contain RIL or baseband bugs that accidentally **** up our IMEI partition/files, so if you have NANDroid backup then try to restore it
hi
Messed little buddy on the phone: /
Namely wanted emui upload 3.0 and it flew nicely (but something to hang the speaker) I returned to the B133, wanted to send service.
What's the problem:
After returning to the B133 at the end of the update shows a "fail" as I take it by adb loading files all fine and dandy, but when you try to reset it to factory settings I set the same, with the wipe on cust option also fail.
Any ideas ??
bootloader unlock

Same thing happened to mine a few months ago, it overheated so I sent it in for repair. Took two weeks to get it back
so how was the problem solved?
what solved the problem? Which Android Version are you in now? Did they fix software or hardware?
LG fixed it, at the time I was on zve. They replaced the motherboard with a new one
