[Q] SIM card problem

Hi guys. Yesterday I changed kernel in my X8 - i tried Alfs v06. I have GDXv.21 and I've got a problem since that time.
My phone can't recognize any SIM card!
It doesn't matter if it is Orange SIM Card, T-mobile or any other...
Any reasons?
Now I'm repairing it with PC Companion but I want to know your tips guys.
Please, help.
Check your x8 manufacture date and has your x8 been sim unlocked?
Let us know if pcc repaired it.

Maybe you can turn on your x8 without sim card
Them put it on again with sim card inside
Dont forger to put sim card in your phone while flashing..

did you try with another sim card?
Try relocking you're bootloader after reverting to 2.1 and then unlock again if required..

"no SIM card detected" after using Flashtool

Hello World,
As I'm a stupid boy, I've used flashtool to downgrade a Xperia Z to a rootable firmware Xperia Z_10.3.1.A.2.67_SFR 4.2.2.ftf
I've then used rootkitXperia_20140719 and XZ-lockeddualrecovery2.8.3-RELEASE.installer
Reboot, every thing seems ok except that my SIM card is no more detected. "Please insert a SIM card and restart your phone".
The SIM card works well in another phone. But I've never used it in the Xperia Z. IMEI is still correct in Xperia.
Why am I stupid ? Because I don't have any backup. So, what could I do now ? I've try touse flashtool to flash other stock roms or baseband without success. :crying:
Really stupid. I found what I've done wrong: I've used Flastool fastboot mode on locked bootloader...
Any idea to solve ?
Me too
Did you find a solution?????

No
Yes, I found a solution: The SIM card was not well inserted. Change the side when inserted (electronic part should back oriented) and everithing works well.
