Not detecting Sim after flash

Hey yall, I am hoping and praying that is someone out there in xda that could help me with my problem. I wanted to install the unlock bootloader on my phone, and I followed all the steps and when I was done everything was working okay except I could not connect to me service provider. I went to my service provider to today and they they changed my sim card thing that it was the problem. Now my phone shows signal when I switch it to GSM but when I try to make a phone call it cuts off..
Has anyone had this issue and if yes how did you fix it ?

Have you ever sim-unlocked your phone? If you have, you need to unlock it again using setool and proceed with bootloader unlocking using the setool.bat, not semc.bat. The same goes if your phone is sim-locked. Unlock it with setool.
If you never sim-unlocked your phone, or it was sim-lock free from the time you bought it, unlock the bootloader with semc.bat.
Now, try unlock the bootloader with semc.bat and see what happens.

Im having a similar problem my x10 have a unlocked boot loader but my phone have a signal problem , the signal is very low
, someone can help me?
Sorry for bad english.

You may have unlocked your bootloader with the wrong .bat file. What .bat file you used?

[Q] T-Mobile data with Sprint HTC 10

I purchased an unlocked Sprint HTC 10 intending to use it on T-Mobile. It seemed to be working okay, so I unlocked the bootloader via htcdev, flashed TWRP and installed SuperSU according to the instructions in the forum.
Doing all of that undid the SIM unlock, so I followed the instructions for the NV unlock from the HTC m9 thread. The phone seems to be unlocked now, as I can make calls, but I can no longer connect to data. I've entered the correct APN settings (same as I did before the bootloader unlock), but I get nothing.
Is there something I need to do to restore my T-Mobile data? Flash a radio or something?

could you get a solution for this. Have the same issue.

LS997 SIM card not recognised

I just got an LS997 V20 and so far I'm really liking it.
However, since I'm using it in the UK, I needed to network unlock it. after doing this, I hoped that I could use my simcard, however (as you can see in the added image) it still shows a simcard error. the simcard works, however since in my other phone its being recognised.
I think I read somewhere that the sprint ROM blocks simcards that aren't Sprint. I tried to unlock the bootloader and fastboot, but haven't been able since I accidentally installed the latest updates. is there any solution available or so that can fix it without needing root or the bootloader unlocked? I really want to use this V20 as a phone and not as just a camera and mp3 player
Is there any way to fix it?

If you have updated your phone to August OTA. Then you will be left with no other option than to purchase a sim unlock.

I already bought a network unlock that went via an app. I bought it from lgsimunlock.com . Any other ideas? I'm not even sure if that network unlock worked...

network unlocking 6p

hi, i just got my (second hand) nexus 6p and so far i like it alot.
updated to 8.1, unlocked the boot loader, installed twrp amd magist to get root all working fine.
the phone seems to be locked to vodafone (uk) as it works ok with a voda sim but when i try a ee sim or 3 uk sim it will not register on the networks and says emergency calls only. the thing thats confusing me is that it does not ask for a unlock code when i try another network sim, every other phone i had has always asked for a code to unlock it. am i missing something or is there another way to input a unlock code if / when i get it from voda or a third party unlocking provider?
cheers / thanks

You might be right but the solution is there check out this page https://support.vodafone.co.uk/Usin...one-device-if-I-m-not-a-Vodafone-customer.htm

thanks to a message from Exodusche my problem is solved. the phone is not network locked at all, when changing the sim for some reason i had to turn off the security pin then reboot the phone and as if by magic after that i had service and everything working fine. some sort of glitch in 8.1 i guess.

How can I add my device for bootloader unlocking without mobile data?

Hey guys, so I accidentally locked my phone, and to unlock it again I need to add the device to my account then wait. But here's the thing, it won't let me do it on Wi-Fi, for some stupid reason it needs me to do it on mobile data only, which I no longer have, and i'm not gonna get mobile data just to unlock it.
Can anyone help me bypass this? I really wanna get rid of MIUI, it's so bad.
Thanks in advance for all the help!!

Nevermind!! I figured it out!! the device is registered even if it says it's not, so I just tried the usual bootloader unlock program and it worked!!
