I'm having troubles with my HTC Excalibur S621, i'm from Mexico.
The problem is that when I put a SIM on it, the screen gets locked with the next window:
FATAL ERROR
DATA CRASHES. PLEASE CONTACT SERVICE.
It only happens when I boot my HTC with a SIM and radio ON, if the radio is OFF or the HTC without SIM it boots ok and can work it without any trouble. I hope you can help me, i'm new to this forum. I've managed to re flash it with several flashes but it keeps the same. Thanks in advance

Have you tried another sim from your carrier? or from any other carrier? is your phone sim unlock?
I had my HTC myTouch4g unlocked by a repair show today. He had requested the unlock code. We put in a AT&T sim vs the T-Mobile sim. Then he put in the unlock code. Now, I can access any of the Google Accounts.
I was using the new Google 2-step verification successful for weeks. But I tried on those codes. Then finally, I canceled or deactivated those procedures. But it still does not work.
Do I need to delete everything by resetting the phone to factory setting?
Will this always happen if I switch sim calls in the future?
Any help would be appreciated. I am glad this happened before I went off to Africa.
Hi, i'm noob and this is my first post. I got the Unlock code from ATT and tried it with my new sim. I was told by ATT that all I needed to to was insert new sim, power on, and the phone would ask for the unlock code. When I did it, it was asking for a PIN#. I entered the unlock code but it kept saying invalid. I got down to "4 attempts left" and gave it to someone at the local carrier. They gave it back to me unworking and now it says "sim error - sim not installed or is invaid. Emergency calls only. The sim is good and I have verified the correct unlock code with ATT.
Anyone know what to do? Is is a brick now or can it be fixed? Thanks in advance
I think you should use Nokia Software Updater for Retail to flash new Firmware to your phone
(Note: losing all data )
Hi guys, I'm trying to network unlock my M8 to use in Germany. I've inserted the card and typed in the network unlock code that I bought. Unfortunately, it is hanging on "Requesting network unlock'
I have tried factory resetting the phone.
What can I do?
Thank you
Are you stock, which carrier?
AT&T Skydragon rom
Try stock rom if you can see if that helps. Do a backup of your current rom, flash stock then restore backup
I'd suggest go back to complete stock also.
thanks, going back to complete stock worked. However my SIM card is locked every time I turn on the phone.
What do you mean your SIM card is locked? Do you mean you have to enter a pin to unlock the screen?
Network unlock requested?

Hi , I just get a t-mobile HTC g2 as a gift , and after I factory reset it and I got a problem , I insert a new sim card and it request a sim network code !! And I had sent a message to T-Mobile too but they need me to get the phone owners to contact them to get the code !! If I root the phone and flash a new room , will it Fox my problem ??
Yes it should
Flashing a new rom will fix the probem because the network lock on android devices is firmware based. Some sites on the internet provide these codes, tough.
