Hello everybody!
I was on ultimate v8 when my phone started rebooting in recovery without any reason, and entering recovery.if i restarted the phone i didn't had signal.
the phone worked properly without the sim card (tried two cards, it had this problem with both of them)
i thought it was a rom issue, so i flashed the stock rom, relocked the bootloader and used sony update service to repair my phone.
i didn't install any applications, and for a couple of hours it worked normally. afterwards though it lost signal again and started rebooting.
did a clean install again with no results.
any ideas what how should i procceed? is there any way to fix it or shoud i visit a service point?
ps sometimes it seems that sim cards are not properly recognised. it's not that it has the sign, that shows that there is no sim card, however sometimes i restart the phone and it doesn't ask for the pin code

hmm...do a factory reset using cwm then flash stock ICS .54 rom & see it works or not.
i've wiped data, cleaned cache, dalvik cache etc many times while i was on ultimate. i've also flashed the stock and did factory reset via the menu in the phone as well via sony update service... i was thinking of flashing radio, but couldn't find the file...

After a normal reboot of my phone, it suddenly doesn't read my sim card anymore. When I turn it on, I'm not asked to enter the pin code and the phone doesn't connect to the network.
If I go into settings and change the pin code, or turn it off, I'm asked to enter the original pin code, so in that way there's still a connection to the sim card.
When I've done any of the above, the sim card seems to been "activated", and the phone connects to the network, and everything is as it should be until the next reboot. Then I manually have to "activate" the sim card again.
The phone has worked without any problems for a long time with the current CyanogenMod 9 custom rom and my current provider, and I haven't changed anything that suddenly can cause this.
Some suggestions to what can be wrong?
Does the sim work with other phones ? If so, it probably isn't a problem with the sim. In that case, try a factory reset in the first instance.
If that fails to work, try a fresh/clean install of CM9. If that doesn't work, reflash a Gingerbread stock rom & see if the problem persists. If the problem persists with a GB rom, then it's likely to be a sim/hardware issue.
The other thing that comes to mind is have you flashed a recent CM9 nightly ? This might explain it working OK previously with CM9 & not working now. Obviously CM9 is beta, and something funky might be going on with a more recent build/nightly.
I've now finally managed to find another phone and another sim-card.
My own sim-card works fine in the other phone - and when I put the other sim-card in my own phone it doesn't ask of the pin-code and it doesn't connect to the network.
So I believe my phone needs a complete reset - when I've got the time to do it...
One strange thing is, that at one reset earlier this week my own phone asked for the pin-code - but only once...??
I think I've found the problem. Either it's caused by Avast Anti-Theft alone or it's a combination of Avast Anti-Theft and CyanogenMod 9.
I believe it's the last one, because everything worked fine during the first time I switched from stock ROM to CM9, but then suddenly the error with the pin-code occured, and I could be caused by an update in the CM9 version.
But when I restored factory settings on my phone and started again from zero, everything was okay, and I was promted to enter my pin-code. It was the same when I restored my apps and data with Titanium Backup, but then when I installed Avast Anti-Theft the error occured again.
Actually I restored my phone once again just to make sure, and it was the same - when I installed Avast Anti-Theft, I was no more asked to enter the pin-code and the phone did not connect to the network.
So now I know what's wrong and maybe also why - but I don't know how to solve it...!?
So,
I bought this phone on the day it was launched, its been more than 3 months and had no issue with the device. I rooted the phone , experimented with Xposed and other apps but for the past few days i was experiencing this strange problem. Cellular network was not running on my phone, i changed the sim, swithed the devices on/off several times , did everything i could do in the os, changing the mode to 3G from LTE and vica versa, etc etc .. but still no luck. The cellular network sometimes comes and goes. Then i opted for last resort which was to factory reset the phone, after resetting it the cellular network worked but i don't know if this is a permanent solution. If you have anything to add please share.
Regards,
Saransh
Sorry nothing much to share but i suspect you install some apps or did something to your rom so the network screwed. My suggestion is you nandroid backup every week (at least) so you can revert back when something happened.
Tried factory reset
I have tried factory reset but still having this issue. Maybe it's a hardware issue. I don't get it , everything was working fine few days ago then all of a sudden this **** happened.

Maybe exposed screwed something. Get a microsd card with whatever rom you want in it. reboot to recover and try full format. insert the microsd after then flash a rom. see if it works
Rooted my phone with sudamod rom, Everything is working fine.
I wiped my LG G2 (vs980...unfortunately) on Monday from an old custom ROM and installed a new CM mod (13). Since then, the phone won't recognize any SIM inserted. I wiped all again, and installed CM 12.1. Same deal. Went back to CM 13 and nothing. Now upgraded to RR 5.8.2 (latest they have for the vs980 model) and still nothing. Everything else works great (apps, wifi, bluetooth, etc), but it still does not see any SIM. I also noticed that when I go into settings and select Cellular Networks, I get a "com.android.phone" error (Not that annoying "Unfortunately..." mess people used to get and it asks if I want to close the app. I have tried clearing all the caches and app data, going into test mode and turning off the radio (several times) for up to an hour, powering fully off, removing the SIM, leaving out for an hour before reinserting and powering back up, and even changing the IMEI number and nothing has worked. By the way, using TWRP 2.8.6.0 to flash my drive.
Oh, and I used 3 different SIM chips and they all work fine in a PUK.
Someone please help. I can't afford a new phone right now.
Thank you for reading my question, really appreciate if someone can solve my problem.:angel:
I have a LeEco le 2 x526, in which i removed the stock EUI rom and booted a Custom Rom Lineage OS, everything was well and fine for about 2 months then one day suddenly the phone froze and switched off.
I tried factory resetting my phone, re-flashing the phone but nothing helped it still does the same thing, i have to hard restart my phone by pressing and holding power button, when the android boots all the time and dates are messed up after getting the signal everything is back to normal.
I tried restoring my phone to stock Rom by recovering from backup image before installing custom Rom but after installing, but the phone is stuck at first boot screen, even tried downloading stock Rom and tried that same result. I waited about two and half hours before giving up. If i try to install again Lineage Os it boots correctly with no problem. But can't restore it to stock Rom.
One thing i suspect when the problem started was that i change my sim card to a new one, before i was using Jio 4GLTE sim card in the phone & then i switched the sim card to Airtel 4GLTE. Is this due to the sim card or signal or my phone is having issue. The Airtel was alwasys my secondary sim in my phone but never used it for data Jio was my data sim card, now i am using Airtel as my data sim card.
Hello, do you find any solution??

Is there a solution, because I have two phones with a german provider O2 with the same problem.
Hi all,
I am completely stuck with this, I couldnt get any wifi it wouldnt turn on and when I did it just turned off again. It also wont read my sim card and randomly restarts.
I tried factory resetting but its now just stuck getting me through the android setup and needs internet in order for me to register the account that I previously used on the phone, otherwise it wont let me pass. It wont turn on wifi still and still doesnt register my sim card.
Please help as I have been trying this for hours and Im honestly at the end of my rope.
Cheers,
Evan
