The phone (locked to fido) comes up saying.. nothing not even a notfication that an non fido sim is in the phone
as well i have not done a thing to the phone other than update it to the newest android version through LG
the phone turns on and on the lock screen says no network then say no sim card.

I recommended going back to stock froyo 2.2 and turning the phone off then put the new Sim card in and start it up and it should work. I had issues unlocking until I just flashed back to factory and then it worked like a charm. Good luck
Pin it to Win it.

would you have a guide to reverting back to stock 2.2?

I don't have the link handy but if you search for stock 2.2 rom you should be able to find it. You just flash it and unlock, then restore your rom and done like dinner.
Pin it to Win it.

nope
I am on android 2.2.2 now and still geting network unlock request unsuccessful when entering the codes and yes they are real codes and the number match up with my imei
what is going on??

I used to have this problem. A quick battery pull always solved the issue.
It doesn't happen to me anymore though.

still on going for me lots of battery pulls

Any update on this thread... Im having the same problem

Simlock issue in bootloader after rooting

Hello all,
I was curious on what it was like to root my inspire 4G and so i went for it and everything went swimmingly, i achieved S-OFF and everything but then i realized i wanted to go back to stock for one reason or another (mainly because im squeamish) and so i flashed the phone with a stock ROM, but i accidently hit the SIMLOCK option in the bootloader and although it said that it was unsuccessful, when i turned on the phone i had no service, i took the SIM out and put it back in, no luck, i tried pressing SIMLOCK again in the bootloader, no luck, I am stuck now. i would also like to know how S-OFF is beneficial, and does it matter if it is off if I have a contract with AT&T. please help me get my sim card working again
Well, I did something similar to a friends phone before, he had a lock on his DON so every time he turned on his phone it would appear. And so after 10 unsuccessful tries at getting in the phone locked/burned put the SIM, he had to goto ATT and get a new one...

[Q] No sim card - no service after unlocking

Hi all, I think I looked everywhere for similar issue, including xda, but no luck. I got my "new" Sensation yesterday and, obviously, I wanted to have a custom rom as I do on my Desire. So I unlocked the bootloader and flashed both recovery and new rom (yes, the phone is still S-ON because I just couldn't get it to S-OFF, no matter what method I tried there was always an issue and I couldn't complete the procedure. if it's important I can explain in details what I tried/not tried). Right now it sits on CM-10.2 | AOSP 4.3 Jellybean [KANG] with 4EXT recovery. Everythin is fine however the phone is locked to O2 and I'm with T-Mobile. I tried to get the phone to S-OFF in order to remove the simlock myself but as I mentioned, no luck. So I got pissed off and I bought the unlock pin code. I've inserted my T-Mobile card, phone asked for the pin, I've entered it and boom, phone is unlocked. Great, I think to myself... well not really. One, the phone just won't get the signal (and I tried putting it to GSM mode only) and two, every time I reboot it the message to enter network pin come up . So I enter the code again and that's the end of the loop. Tried hard reset after entering the pin code but after a reboot it would still ask for the unlock pin and then won't pick up any signal. I've tried giffgaff sim card and that works straight away (as it works under O2) so it's not the phone issue (well, not the sim card port anyway).
Any ideas/solution/questions a-ny-thing would be greatly appreciated as I'm about to rage quit and give up on it .

Hi,
Could it just be the t-mob sim card?
Is there any chance to get a new one from them?

Thought that but the card works fine in my Desire. Never had any problems with it. What gets me is that constant message asking for the network pin after rebooting the phone. Surely once the code is entered the phone is unlocked ...
If I can't find any solution by monday I'll visit their shop and ask for a new sim or I'll just move my number to giffgaff >_>
Obviously if anyone has any solutions or ideas feel free to share them and I will be sure to try them. I'd really appreciate it!!
Sorry for double post

Custom Rom causing phone not to recognize new sim?

I am currently switching our Cricket phones over to Tracfone with their BYOP kits. My daughters' phones are both stock and their phones immediately recognized the new sim. (However, their phones are LG Risio)
My phone has AlexOS 5.0, after trying unsuccessfully the first time to get it to recognize Tracfone's sim, I did factory reset from TWRP. Still no luck.
Do I need to flash back to stock? If so where can I get it?
Also, if stock is currently only on 5.x can that even be flashed over 6.x (downgraded)?
Thanks
ETA - Checked sim card in other phone and it is fine. So it's definitely my phone.
Looks like maybe Mobile Upgrade Q is the answer? Would that make me lose TWRP?
If you update using Mobile Upgrade, you'll lose root, TWRP, and go back to stock.
Does the Idol 3 need to be network unlocked in order to work with Tracfone?
I think so, we have the unlock code directly from Cricket. The problem is that the phone simply says "No Sim" with the Tracfone sim, the others phones immediately asked for an unlock code after switching sims.
Try a different sim card in the phone to see if the phone prompt's for the unlock code? If not prompted, the phone may have to be flashed back to stock.

Sim Network Unlocked S8+ relocked after updating ??

Hello,
I have a Japanese S8+ (SC03J) that was sim-unlocked a bit more than a year ago. I used it on stock firmware, then rooted it, and kept using it.
I was going to update it to 8.0 through this custom firmware :
https://forum.xda-developers.com/ga...g9550-g9500-phoenixo9-crf2-everytime-t3819774
After successfuly flashing it, when I put my sim card back, he automatically asks me for a network unlock code, thing I never been asked before.
I came back to stock firmware but it is still not reconizing my SIM card, and asking me for an un lock network code.
The SIM works completely fine on my other japanese phone.
Is it something that happened to someone else ? Any idea on how to fix it ?
I do not think it is a hardware problem as I didn't do anything unusual.
Any ideas welcome !!
Thanks!
