K550i Flash-insert correct SIM

[Krizak]

Hello. I´ve just flashed my K550 with XS++v3.1 and it says "insert correct SIM card". The SIM card was not in the phone during flash. Need help!:( Thanks a lot

I found that my phone has a sim lock. Found Simpatch generator v2.1 and made a patch. Can I apply the patch with XS++v3.1?And what is needed for the patch application?

Thanks for advice. One more question:how can I find out if my phone has the quick access patch already installed?It is a second hand phone...

It can be determined, but isn't easy for average user... But don't worry about quick access patch, it doesn't matter if it was applied or not. Just follow the guide from beginning.

Jop. Made completely new flash with SETool Lite and applied patches. Everythink seems to work ok;)Thanks mates:)

patch unlock: if you fash your phone phone will lock again. in your case i think someone else allready had aply the unlock patch. do not flash that phone with SEUS,because it will upgrade CID to 53 and then phone needs special and expensive equipment for unlock

Thanks. I flashed once more and it locked again,so found out also,but was unlocking once more:)I cannot use the SEUS,because it says, everytime I try it, that my FW is actual...somehow it doesnt work. I think this is because the phone is from Slovakia and I am using it in the Czech Republic. And FW for Slovakia doesnt contain Czech language,so the shop reflashed it and sold as new one:(Fu*kers...
