No cell network after flashing factory image

Hi,
I just flashed 4.3 google factory image, and everything went well.
When I switch on the phone, it ask me my PIN code, and then, no mobile network is recognized. The problem persists even after a reboot.
I tried with 2 sim card from 2 different carrier, and the result is the same. I'm in France, and the radio xxlj1 worked fine before the flashing of the factory image.
Does someone know what is going on?

I would try newer radios, if possible...

UGLL1 was not better than XXLJ1 before factory image flash. I don't think it is the radio, because it was working before very well with xxlj1.

I have just noticed that I can put a wrong PIN code and the phone can unlock the sim card. Is it possible that the sim card reader is dead? Is there any tool or app to check the readability of the sim card?

I mean it would be one thing if you dropped the phone in water or something... but for it to stop working after flashing the factory image?...
Try flashing the earliest available image, 4.0.4 I believe.

I tried it, without success. I flashed a factory image, because most of times, my phone was stuck at google logo without reason, even after a full wipe.
But now, I noticed that the phone can connect to cellphone network at approx 1 boot over 10. I suppose it is a hardware problem, but it is very strange. When the network is ok at boot, everything is fine until next reboot, when the SIM card is detected, but not read correctly.

No network signal w/ 2 sim card

Here's my problem, I'm on latest cm10.2 nightly and I don't have any network signal...I tried with 2 different sim cards, both can be read with a "Sim Card Reader" from the Playstore but I cannot send/receive sms or call with both sim cards...I tried to enter manually the APN but still nothing...the sim card tray is not broken in any kind...what's the problem? I just reinstalled the stock firmware but no chance, no signal at all...that's weird!!!
Any help or fix are welcome

I've a E975 version and last week I pick up my phone and it was with no signal, reboot and nothing happen, went to a store and my SIM card was ok and a different network SIM card was not working too. The phone was not able to "read" the PIN code (my SIM card PIN is disabled).
I've flashed the ROM again (Savyrom) and I had a subsystem crash and afterwards kernel crash's, the stock ROM backup and kdz installation have not helped either.
Now I've sent it to LG support service because after a factory reset i've lost my IMEI and the phone was rebooting 30s after starting up and I was not in a mood to try to restore the Freegee IMEI backup.
Do you have the IMEI number?

So, here's my problem now...
I just reinstall stock jb firmware on my phone, I can see the IMEI in the setting but I don't have any signal from my carrier...
I have an EFS backup but I think it's broken...Anyone can open it and verify if it's true? I can send those 3 files...

My advice is to send the phone to LG support, maybe you have a SIM card hardware problem... At least you don't have system crash's and reboots like me.
I was with IMEI too I'm almost 100% sure that a lost it after the hard reset.

Hummmm...that's not a hardware problem because the phone recognize the sim card (sim serial number, sim state is ''Ready'', sim country ISO: Ca)
I surely think it's related to the EFS partition but I got the IMEI...that's weird
And I can't send him to LG support because the warranty is over...

1. Try changing radio.
2. Get a new phone. It seems to me that something broke in hardware.

Sim card(1) "Sim card not detected"

hi
I have a very annoying problem whit the sim slot 1 (i currently test the slot 2)
Very often, the phone tell me "Sim card not detected", and i have to open the phone, dismount the card and put in again.. until the next time.. like i said, it's occurs very often, 10-15 a day..
Even when the phone is on the table without touching it..
I have rooting it and thats it.. 2.19.40.22
I would like to know if someone have similar problems before i try to reflash whit older stock rom??!

It happened to me briefly- After flashing my first full back -up back to the fone --then i did a factory reset and this fixed the sim slot problem

Hi, I think i have the same problem after testing the Cyanogen build for ZE551ML. Have you did a factory reset from recovery (wipe data, cache and dalvik) or a full stock rom flash ?
Thanks

Above, I was referring to the full 5gb asus ROM back up I made immediately after unlocking bootloader installing twrp and rooting, I installed svn ROM and backed that up too..stripped svn ROM further..backed that up too. Then went about trying my Asus full original...sim 2 was only detected..so did a factory reset and sim came back.
To get sim recognised in CM,I had to wipe usual..install..set up...and factory reset it...hope that clears it up a bit lol

Oh,try a reboot after factory reset..I forgot to put in description above

Guys can you check your sim holder lock . I mean when you put the sim in holder check if it is properly fitted. Issue is some SIM cards are thinner than normal and sim holder unable to grip it. I faced same issue.

Also recommend using ASUS ZenUI app called ASUS Support. There are several helpful tips with basic troubleshooting techniques for your device including including SIM card troubleshooting. Please go to Apps/ASUS Support/Assistance/SIM Card/Sim card not detected

Sim Card not detected
Hey guys,
I am having a similar issue. I have 2 Sims, AT&T and GCI (local carrier). AT&T Sim works in both Slot 1 & 2, and GCI Sim works in slot 2 only. The AT&T sim is a standard MicroSim and the GCI sim is a Tri-Cut sim, so basically a NanoSim in a Micro Adapter.
Sometimes when the GCI Sim is in slot 1, it will recognize for a couple seconds then go gray..

I subscribe to the "theory" that some SIM cards are thinner than others and they drop out of slot 1.
In fact, I have 3 SIM cards and they range in thickness by around 0.5mm according to my cheap chinese mircometer. I don't believe that it is coincidence that the thinner ones lose SIM detection more than the thicker ones.
Also it is no coincidence that slot 2 doesn't lose detection becuase the SIMs don't slide upwards out of slot 2, but they do slide downwards out of slot 1.
Do this experiment: Put a SIM in each slot, now place a 3rd SIM in the space between the two. You will notice that it sits easily in the gap between the two installed SIMs with a bit of free play. Put the back cover back on and use the phone normally for a while (a day or two). Now take off the phone back and tip the phone over, does the "third" SIM fall on the floor, or has it been gripped by the SIM in slot 1 as it has gradually slid out of its slot?
Since I put one layer of sellotape on the back of all my SIMs, I have not had one single "SIM not installed" message. I used to get them all the time, especially with one of the thinner SIMs in slot 1 and above all when using the phone in the car (the fully vertical position and the vibrations seemed to have accelerated the SIM slipping out of its slot).
By the way, I never had the SIM slide completely out, but they certainly are not gripped sufficiently in place and slip enough to disconnect.

I had same "sim card 1 not detected" issue.
It worked back when i did soft reboot,.
And no more issue after factory reset

Re @ leftrand earlier on page 1.....
Sorry not been here in a while , but I think this was related to an earlier twrp we used , fixed with the later one I think. So it was a matter of restoring full original bk up,then factory reset then set up again and do another bk up. Keeping original bk up just in case . That was a while back now and should be fixed

facing same problem... only after updating ota. always.. sim 1 is not detected...

That no way to have a sim 1 working thru TWRP back up after flashing the CM13. What I did was doing a clean flash with SuperZen - 2.20.40.156 Full.
The problem was solve. then I flash back my back up TWRP. The phone now work like a charm.

I got it fixed bro! the phone does not like the Nano sim cards in the adapter. I happend to find an old GCI micro sim and had them activate it. works great now.

ok i found a solution. i read a earlier reply saying you cannot assess sim 1 whilst using a recovery back up flashed. i was currently using cm13 nightlys and this morning i flashed paranoid 5.1 or so.... i wanted to go back and compare the two but what i did was restore it from a backup.... so what you should do is when wanting to change roms, KEEP THE ZIP FILES THAT YOU USE TO FLASH THE ROMS WITH!!!!!!!!!!!! im still asking you to back up roms (preferably system before you flash) just so you dont hard brick it.
bottom line is back up rom, but keep zip files for when you want to change between roms. hope i can help

I have this problem, compounded by the fact that it seems all Android 6.0 (or possibly all CM based ROMs for the ZenFone?) have an issue where losing cell signal in a dead zone permanently breaks the radio until the device is rebooted. Even if the SIM is recognized, after going through a no signal area, the signal never gets acquired again and the SIM information lines remain blank or unknown. Trying to refresh the networks or providers list throws an error toast.

Question Z Fold 3 constantly reboots

Hello, guys
first sorry for my bad english
I will try to describe my problem
so my fold 3 keeps rebooting, but only when I'm not using it, only when it's locked and nothing is running in the background. So far, the only way it works is to turn on the app from the local radio and the volume to 0 ☺☺☺ so it has to work in the background and if I put it on pause it reboots... please help
I tried everything I found on the internet:
- put official android 13
- factory reset
- after factory reset, tried without installing new apps
- battery device care > auto reset OFF
- deleted wipe cache
- safe mode > reset anyway
- test using Samsung Members > everything ok
I have no more ideas

try these:
remove sim card and see if reboots
plug in charger and see if reboots
put in the fridge and see if reboots
let me know if it worked

So i put wife sim old sim butt same operater and it reboots after 3min
I will try sim with different operater

ok so i have news
i try with different sim new one from tcom and same problem. after 5min it reboot himself
i go to my operater for new sim same problem it restarts
then i got mad and do factory reset butt this time without logging on google account or Samsung acc
and now it past 2h and he didn't restart
please guys help !!!!! don't know what to do

So after that, restarts with only insert sim card to device even new one for me looking like unfortunetly hardware issue and need send to service.
Esim in my opinion didn't resolve problem or only in half because device will be full working especially with sim card which enables fundamental function of phone like connectivity.
