[Help] Phone can't find SIM after downgrade & upgrade - LG G Flex

I just downgraded from 4.4 to 4.2 temporarily with .tot files and when I flashed back 4.4 the SIM card can't be found at all even after a factory reset. Anyone know how to fix this?

Try to downgrade to 4.2.2 and after you must do factory reset with the hardware buttons. After that your phone should be work fine.

Issue resolved itself with just a flash back to 4.2. After the flash it found my SIM. Weird thing is I did this twice earlier today and it didn't get fixed then. So I just flashed back 4.4 after it worked again now and it still found the SIM. Weird stuff. The G-Flex has made me nervous twice now though I'm a pretty long time flasher. Things are a tad different with the Flex it seems.

[Q] Signal Issue

I flashed omars rom about a week ago and everything was going great until this morning. I woke up and have no signal at all. Rang my operator, they said there's nothing wrong with the network. I've tried everything I can think but nothing. I've flashed different roms, kernels and ended up using rsd lite to go back to stock, and still no good. Anyone have any ideas? Any help would be greatly appreciated!!
It can be hardware issue. If flashing full stock rom didn't help it shouldn't be software issue.
Download any app to enter radio settings and change to only 2g but it must be changed in radio settings, not just phone menu setting. If it wint help on stock full rom for 90% it gonna be hardware issue.

[Q] Network loosing service after update to OTA 5.0.2

After i've upgraded to OTA 5.0.2, the 1st SIM card is repeatedly loosing signal.
This didn't happen with 4.4.4, that came pre-installed.
I've read that moto g has had some problems with signal loss, but i think it's related to the 1st generation moto g.
Any idea of what i can do to identify/fix the problem?
I'm considering downgrading to 4.4.4.
Many Thanks.
Edit: After the upgrade to 5.0.2, i did a factory reset.
i to facing this issue.

i have noticed this issue with my phone too, after upgrading it lollipop, suddenly signal drops on both the sims.
Actually one particular SIM card losing signal was very frequent while my phone was on 4.4.4 . Sometimes it couldn't be fixed even by rebooting the phone, and the only way was to remove the card and re-insert it. After updating to 5.0.2 I've seen in happening a couple of times, but it's not that frequent. And it's affecting the same SIM card.

Signal and calls problem!

Hi everyone! My HTC one m7 has some signal problems. Sometimes the signal goes off and I have to restart the phone to have signal again. Also sometimes I am not able to make any calls even though it shows that I have full signal. Is this a hardware problem? If it is, do I have to replace the antenna?If yes how and which part do I have to order? I heard something about installing a different radio, will this help? Thanks for everyone who replies!

Is the phone stock?
If no returning to stock using a RUU is the 1st troubleshooting step you want to try
if yes, did you tried a factory reset first?
If the phone wasn't stock then reverted back to stock and still having this issue ist probably hardware related.
If the phone is stock and you have tried a factory reset then its probably an hardware issue.
Wouldn't hurt trying updating the radio or updating it if you are not using the last one for your version.
Yes the phone is stock. How to see on which radio am I on? Is it a chanche that I won't have install the right RUU for my location,and that's what's causing the problems?(The phone came with supercid)

Need help! My g2 is not detecting SIM card

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!

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

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
