Thanks a lot bro for answering all of my question. One more thing that i confused on the parted command is that needed an SD Card to work ?
Not bro.
That command /sdcard/ is your phone’s internal storage not an external SD card.

First Lock your bootloader then unlock bootloader. Sim card problem will be fixed. Because it worked on my Poco f1.
Both windows and android are working ?
I don not know whether @Marzanul_Islam 's method will work.
But you can recover it from qcn file, using qfil or qpst.
Hey you got the sim card working in windows 10? Is it only windows 10 that it works on? have you tests windows 11? Im getting a poco f1 next week and already ordered a 1tb micro sd card from sandisk official website to use for gaming. I was told by Sophon that sim card are not supported yet on windows but you seem to have them working, did you have to do anything custom to make it work? Or does it just work natively?
Sd card not working
I never said SIM card doesn’t work
Oh no i got the two confuesed! Looks like im returning my 1tb micro sd card if i cant get it to work… RIP
