Need help! My g2 is not detecting SIM card - Verizon LG G2

Hey guys, im writing from Argentina, as a final resource..
I have a vs980, running Cloudy 3.3 LP. As I was having a lot of issued (battery drain, wifi lose, etc) i've decided to go back to stock.
I used a guide found here, with tot file, wich took the phone bak to JB, rooted and with twrp. I've downloaded CLoudy 2.2, and KK baseband, flashed them both in recovery, but when phone starts up, the signal bar is with a red X.
I've tried EVERYTHING, and nothing seems to bring the signal back..
I messed up and lost the phone completely? or theres ir ANY way to bring it back alive??
Thanks a lot!

/any update? I'm having the same problem

This happened to me couple days earlier while trying custom roms. What i did was wiped the custom rom installation, installed by previous rom from backup and its all good.
In your case, i recommend you start from the beginning, flashing kitkat and then upgrading to lollipop and then u switch back to other custom roms.

Pull sim card. Turn off phone and let sit for at least a few minutes. Really.
Then insert and boot back up.
I had this problem and was told to do that and it worked.

hi
i have same prob after upgrading to lollipop , so i downgraded bac kti kitkat still no signal i tryed the power off and wait a min with the sim removed i turn it back on i will get my service back but after maybe 30 secs its gone

Flashed kdz with lg software, imei and boot problems.. Help please

. 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.

No Signal or No Touch

I'm pretty desperate right now as I'm trying to fix my phone for like 24 hours straight and searched the whole ****ing internet for a solution and my eyes are popping out any moment. My situation:
I have a HTC One from Vodafone Germany with LTE.
I rooted it with the HTCdev.com method described in this tutorial:
http://forum.xda-developers.com/showthread.php?t=2292729
After that I put CM10.2(Android 4.3) on my phone and for the first two days it worked quite ok but since two or three days I get no signal at all. The APN settings are definitely correct. Then I decided I try to go back to stock and that's where the next problem pops up. It seems that I can't go back to stock because when I do my phone wont react to any touches at all. It seems this is a common problem when going back from 4.3 to a lower version (as the nandroid backup of vodafone stock is 4.2.2 or 4.1.2). Because I used the method mentioned above I'm stuck with HBoot 1.54 and S-On so I can't do anything about that touch problem it seems and on 4.3 I don't get any signal at all (WiFi working, just saying). Even tried Pac-Man Rom, still no signal at all. Can someone help me in any way? No one can call me or text me for two to three days now and this is a really bad situation!
Hope I did not miss anything!

have you tried to flash a stock RUU? http://forum.xda-developers.com/showthread.php?p=39588860
As I already mentioned... Yes I did and then the display wont recognize any touch input
Have you tried flashing the TWRP for the newer drivers and seeing if it responds?

It's not the recovery where the touch is not working. Recovery is working fine. As soon as i flash the stock rom and boot, i cannot type in my pin, because it wont react to touch.

[Q] HELP No service after reverting to stock from beanstalk rom

Okay So first of all, I flashed the new beanstalk rom yesterday and I didn't really like it and I didn't have a nandroid backup so I just ran the ruu and reverted back to stock and then re rooted. But ever since I reverted back to stock I have no bars. It says I have 4g but I have no bars. I can go on the internet but I cant make calls. When I flash the beanstalk rom it works and I get service but the second I go back to a stock rom or run an ruu the service is gone again. Any help would be greatly appretiated. Thank you
If your running on Sprint's network do a ##72786# from your dial pad and it will begin a hands free activation and just let it do its thing the only thing you might have to do is press either an OK or even NEXT.
I hope that helps. :good:

N4 unable to connect to network..Help please!

Hey everyone, so I just recently upgraded my Note 4 from KK to LP, but during the process, I had to flash the Baseband and modem before I flashed the LP ROM. I then flashed the ROM after I did that, and ended up with no network... I'm still able to make calls ONLY when I'm connected and close enough to the WiFi, texting is still fine I believe. So then I tried going through the process of downgrading to see if that would relieve the problem of my network issue, but it still isn't even working. Even after doing the process in reverse, flashing the baseband and modem before flashing my ROM.
I'd like to add that I did take apart my phone because my screen needed replacing, so I took apart my phone to see if I made my signal cables loose, they were, but then I popped them back in again, turned on my phone to see if that was the issue, and it still doesn't work, as well as my hardware back button doesn't work anymore so I have been using a nav bar to access my multi-window app.
I have tried flipping my signal cables, going from LP to KK, KK to LP, and reinstalling the firmware...
Edit: Whenever I factory reset in the stock recovery, I get an " Error:failed to mount /preload (no such file or directory)
Have you odin'd to stock lollipop?
You need to Odin stock firmware from Samsung, this will fix what you borked.
Then you can try again.

I've tried 2 fresh downloads of the stock firmware and it hasn't worked, but I will just download the file straight from Samsung this time to see if that could fix the problem. My new signal antennas I ordered from ebay are on the way and should arrive tomorrow. I'll then try that if this troubleshoot doesn't work because I don't have any 4gLte network at all, and it only pops up randomly and at certain areas I drive. I'm constantly moving and I could never have a stable connection, no calls, no text messages till I'm connected to the wifi:crying:
Edit #2: So I have installed new signal cables, and still not getting any 4G/LTE Network. I have constantly checked on my wires to see if it does anything to the network, but it doesn't. Still able to make calls on Wi-Fi only ): And I have used Odin to try and revert back to stock fully and no luck..

LG G4 Loses Network After Root and ROM Installation

I recently rooted my H811 G4 (T-mobile) and then installed the latest Imperium ROM on it. Everything worked fine for three days. The only thing that kept popping up was an alert from Lookout, saying that the Imperium Settings app had riskware and wanted me to delete it. I just ignored the warning as I figured that it was being fussy over an app from a custom ROM. I also kept getting notifications to upgrade my version of Android but I ignored those too as I learned that with a rooted phone, it either won't work, or will unroot the phone. After 3 days, I suddenly lost connectivity to the T-Mobile network. Could still make calls and text over wifi, but nothing when the wifi was off. After going into the settings, it would say that the network was disconnected. I took the phone to T-mobile and they tested the sim card in another phone, to which it worked just fine. So that told me that something was obviously wrong with my handset. I restored the phone back to factory default and was able to make calls again. Imperium was still installed on it. So I went back into recovery and wiped the phone clean. After selecting to restart the phone in TWRP, I got stuck on the bootloader screen. So I downloaded LG Bridge and got it working again. I was going to wait till I got a notification to upgrade Android before rooting it again, but after 2 days, I never got it. Has anyone else had this happen? I thought Imperium was cool but I'm not thinking of just going with another custom ROM.
