I'm new to this.
A totally random event. I restarted my phone one evening last week and it show no sim. Using the LG support tool I had multiple failed attempts to update the software. Then as sudden a the sim registration had disappeared it came back to life. All fine until again the phone just stopped registering the sim.
Phone is secondhand. And I have tried numerous times removing, cleaning and replacing the SIM. Tried another active SIM on the same network with no luck.
I've never had a 'bricked' phone so don't know what to expect but I imagine the phone wouldn't even boot up!
I have now rooted the phone and installed CWM recovery, still no joy and have in desperation performed a hard reset. Nada!
Software is V10h. I read something about EFS folder to backup but all I could find is a text file. The IMEI is not registering on the phone. It could be a very simple answer but currently I'm stumped. I have requested a replacement SIM but have little hope this will resolve the issue.
I hope someone has an answer...

re-flash 10h or 20a kdz. look for various tutorials on the forum. (btw, your phone isnt registring on network cuz your imei isnt being read, probably due to failed upgrade process
(or some other bug). it should be fixable though)
also, replacement sim wont help. its your cell phone that's faulty, either hardware or software, not the SIM itself
also, i'm not sure how it goes if your IMEI is blacklisted by your cell phone company - is it possible the phone was stolen? perhaps the original owner reported it stolen to his carrier and they blocked the IMEI?

If the IMEI is blacklisted, the phone will still show it correctly in the settings and the carrier will just block based on this. This is why changing an IMEI is illegal in most countries and why discussions on how to change it aren't allowed on XDA as it can get the site in serious trouble.

check if ur gapps are fine. reinstall all gapps. maybe u deleted some app that u shouldnt. happened to me too 2 weeks ago and i had no sim so signal , i couldnt see my imei, etc. if that doesnt help , then reinstall ur rom or install a custom one. I mean maybe u must be sure to check if u deleted some system app that u shouldnt. Since u have double checked with other sim , if its not from an app , then the above thread is right, the owner could have reported the phone stolen

Okay, strange happenings with this phone. I've not hd the opportunity to re-flash as suggested but by the by I put my SIM back in and it worked fine. IMEI registered in the phone settings and all was as it should be. Until again first the signal disappeared and when I restarted the SIM did not register. Has anyone experienced this before?

There have been some problems with this, but normally due the the RIL on CyanogenMod-based ROMs. I would suggest that you find the time to either reflash v10h or upgrade to v20A/B/C (as appropriate for your region) and see if that fixes it for you.
you still havent mentioned anything about gapps. this means you checked and you are sure that they are fine ??
So I have tried flashing software V20A using the LG software updater and now all I get is the phone booting into 'S/W Upgrade please wait while upgrading'
I can get into any other screen, despite pressing all combination of buttons together.
I have attempted reflashing back to V10H and try and get it back to how I had the phone. No luck there
And also tried again with V20A. No joy.
Is there anything else I could try?

Yes, Follow the instructions to flash a v20x KDZ EXACTLY and look at your drivers.

Which version of instructions is definitive? I've tried multiple methods with battery in and out. Are you referring to the LG drivers?

I have always found this thread [TUTORIAL]Update firmware through flashing the kdz files( With Picture )Step by Step works perfectly every time.
Got the same problem here, running cm for a month with no probs, restarted phone and sim not recognized. Installed a backup of the original rom and everything ok. Reflashed kdz's and did a fresh install of cm and still no sim. Am now on Zaiben which is ok but takes about 15 mins to recognize sim?

hi, sorry but no, i think it was probably hardware related as it would no longer allow me to flash kdz's.

Then you have some issues with that Cynagenmod, and how to fix that I don't know. Maybe you should try different Rom or flash different Kernel only.

Hello everyone. First of all, sorry for the long post.
I just bought a OnePlus 3t three days back. Updated it to oxygen 4.1.3 and then rooted it as well. Everything was working fine. But then I decided to downgrade to 3.5.4 since I wanted to try out Xposed Framework. So I downloaded the OS from OP Support website, and went to twrp recovery and installed the os 3.5.4 from the internal memory of the phone. It seemed to install properly but when I rebooted the phone, it started asking for a password. I tried every possible combinations of my passwords but to no avail. I saw online and found some video where I was supposed to flash a new recovery which I did. After that the phone got stuck in Bootloader. There is no bootloader and recovery version detail available on this screen.
If I try to restart the phone it gives me the following error, "Decryption Unsuccessful - Your phone storage has been damaged, unable to read data stored in your phone! To continue to use the phone, you need to reset the phone." There's a button at the bottom of the screen to Reset Phone. When I click that the phone goes back to bootloader mode.
Please help me out here. I have no clue what to do right now. I have tried flashing several recoveries but they give an error "cannot determine the image filename for abcd.img"
Any and all suggestions are welcome. Thanks in anticipation.

Thank you for the reply. I haven't yet tried it, since the computer recognises the phone just fine. It even shows up in the fastboot devices list in cmd. Maybe, I should give it a go.

Ok so I did manage to reinstall twrp. But I have no idea what to do next. Any suggestions ?
I managed to fix it. After the twrp recovery was installed, it started asking me for a password. Which I tried and didn't work. But then I just wiped the phone and it went back to factory settings somehow.
Now the phone is back to oxygen 3.5.4 and works fine.
Hope this can be helpful to someone else.
I'm glad u fixed it
Can u please post the correct steps to avoid this issue in the first place .
I'm on 3.5.4 but I may want to try latest versions and come back to 3.5.4
Hi all. I never posted anything here. This is my new post. I don't know whether I can post here or not. Please allow me to post here the moderator.
I'm doing this because I don't have another way. :crying:
The problem is I tried to revert back to stock android, first time I got Odin flashing error. So I searched and found a solution. So In that way I done. But it shows "use emergency recovery mode in smartswitch" so I tried that also. But in smartswitch the firmware is not showing.:crying: It says check the S/N and Model No. I tried so many times.
At last I found a way that, when I face the error I flashed stock recovery and reset the phone and it turned on. I was very happy. But in other side it shows as On NXT. IDK what to do. And device status still Custom, although I've done it through Odin. :crying::crying::crying:
This is the main problom that I'm facing. If it familier to anyone of you, please help me. I'm in this problom since 3 weeks. If anyone can help me it will be really great for me.
Bcz of that I flashed a custom rom. Now I'm on it.
IF ANYONE CAN HELP ME PLEASE REPLY.
