Hello everyone.
Today I got a problem, my Xiaomi Mi9T (global miui11 stock clean installation) didn't recongnise my SIM Card.
I tried fixing it by switching to sim card 2 or placing 2 sim togheter, or trying the sim on another phone (in this case it worked).
Tried formatting everything, not working.
Still the phone can't read it.
Now I ordered on Ebay a new usb-C connector (with Sim card reader, and in the meantime I wanted to unlock the bootloader to get to the dark side of Roms and modding. (The connectior+SIM card readers will arrive hopefully before next friday/saturday morning)
Went to mi unlock, followed many guides but everyone stopped to: Unlock bootloader requesting phone validation, then 168h to unlock.
Can u help me resolve these questions:
- 1: Can I fix the SIM card Reader? (Or the software)
- 2: Can I unlock Bootloader without phone validation?
- 3: Can I get a D*u*m*m*i*e*s* walkthrough to unlock this bootloader and install a custom rom?
Thank you in advance.

Hey did you fix it?
Hello, I'm sorry I didn't find a real fix for it, I just found that my cable ( sim card to main board cable) wasn't perfectly connected, after pushing it back in place, it started working normally.
I suggest you to do the same if you have the same problems

hello guys
today i bought the optimus gt540, and played with it for a while without a sim card in it. later when i inserted a brand new sim card, the phone didnt recognise it, says invalid card. the card works on other phones, and other cards work in the optimus.
i also put a pin code protection on the sim, and when optimus starts up it asks for the pin code.
please help
If you got an garanty for the mobile, take it to the service, if not, flash your mobile with mur4iks latest swiftdroid and i think it would work !
wish u luck !
It doesn unlock phone when you put murik's swift.....
Any other pin unlocker-generator ?
I have this problem for the past two days. It was working fine for a week and yesterday I tried installing clockwork, I installed androot and rooted my phone, installed super user and Rom manager.
While restarting my Rom in recovery it got struck and I had to remove the battery to reset it.
After that I booted into stock orange rom and the sim was not recognized.
I am not sure whether this is a hardware problem or the problem with software.
I tried these things before posting here
1. Tried various custom roms ( CM7, Swedish Spring Rom) to check if the problem is with software. While installing SS2 I tried replacing the sim and this time I did it a bit different than I usually do, instead of putting the sim and then the battery I did the reverse and when I booted into SS2 I got the sim detected. I had left that in my table the whole night and what I saw in the morning is that the phone again displaying the same old "No Sim Card" message.
2. Had put a paper flap above the sim while inserting the sim - Not worked
3. With a sewing needle I had raised all the 6 sim contacts in the phone and then inserted the sim - Not worked
4. Pushed the sim towards the battery side a bit - Not worked
Guys please help me in resolving this.
Whether this is a hardware or software problem and how can I debug these kind of issues.
Please help.
Did you try inserting another orange sim? you should send it back to orange :/
Have you tried the Sim in another phone? I had this problem and the contacts on the sim were worn.

Hi,
Dont ask me how, but I managed to go through wrong sim unlock codes for 10 times in a row and my phone is useless now.
Does not accept even the original sim card - message goes like too many attempts, only emergency calls allowed.
I have tried hard reset but no luck.
Now I do not need even to sim unlock it because my son will continue using it with the original sim card.
Please advice.
Hello everyone !
I have some issues with my sim card on OpenBeta3 + custom kernel (Bluspark).
One day, without doing anything, sim card suddenly being not recognized on each slot, swapping slots or rebooting doesn't have any effects.
(My sim card is good, tested with an other phone)
Catlogs says about a "CARD_IO_ERROR" when sim disappear.
I've done full factory reset or resetting network settings and it didn't solve my issue.
Then i flashed full stock rom by fastboot way + reset network settings, it seems to solve the problem (waiting some days to see if this problem occurs again).
Is there any people who are experiencing some sim disapearring ? And how you managed to solve that issue ?
Thanks
