[Q] No sim after lollipop update on moto x

Hello everybody,
I have a moto x (1st gen) and I did a full unrooting and flashed back to stock to be able to update to lollipop. While flashing to stock, I took out my sim card to avoid loosing all my contacts (I know I made a big mistake!), and after that, even with my sim card inside, it keeps telling me no sim. Is there anyway to fix this problem?
I already flashed back to stock 4.4.4 with the sim card inside, and it also said no sim. I updated again to lollipop and same thing. I would be grateful for help with this.
Thanks.

I've tried that several times and it has been to no avail. I don't know what happened this time I did a full stock flash, but right now, it is showing INVALID CARD - EMERGENCY CALLS ONLY. I've changed sim cards and reinserted the sim several times, but... same old INVALID CARD shows up.

Perma-lock on g3 AT&T after flashing stock firmware.

My g3 was working fine as i bought it from a shop. But later it started going into a bootloop. I flashed the stock firmware but still it goes into bootloop when i insert a sim. and the network is also permanently locked when i run it without a sim. what should i do? i am using it with a non at&t sim.

Can a custom ROM corrupt a SIM card?

I have an unlocked/rooted XT926 and recently flashed CM12 nightly on it. I am unable to get 4G with a Selectel (Verizon) SIM in the phone, but 4G works fine with a Verizon SIM in the phone. Selectel rep is saying I "damaged" the SIM with a custom ROM and they won't replace the SIM. The Selectel SIM also doesn't connect 4G in any of 2 other XT926s nor in 2 XT912s, two of which have stock ROMs (though rooted). Is it possible for a custom ROM to damage or corrupt a SIM? I think it was bad out of the box, does this happen?

Rooted g930u won't recognize Verizon Sim

Not sure if anyone has run into this at all but all help is appreciated. I rooted my unlocked g930u. Its on the latest firmware for the unlocked variant. I installed my Verizon sim card and a message popped up saying g it had to restart to download carrier specific features. When it reboots, it reboots into recovery mode and gives me a DRM has failed message. I'm not sure why this is attached to the sim card because if I restart the phone wothpout a sim, I can use it normally. Thanks guys

Network unlock

I bought a used note 5 T-MOBILE 64 GB that was unlocked yesterday. My sim card was working fine. I installed TWRP recovery by ODIN and after installing it my phone boot-looped. So, I installed "no-verity-opt-encrypt.zip" file and rooted the phone with "BETA-SuperSU-v2.68-20160228150503.zip". After that the stock rom booted fine but I the phone turned on it gave the error that non-carrier sim was inserted and the sim did not work. I tried formatting the phone. Installed the nougat firmware updated it and the problem still persistes. Is there any way to remove Network lock? I would appreciate your help greatly
