Hey guys,I was trying to unlock LTE bands on EEA mi 9t (BAD DECISION, DON'T DO IT!) following any of those tutorials and i broke:1, mobile network2, wifi3, diag mode/portWhat i did:- I have root with Magisk, used 'adb shell / su / setprop diag,adb' to enable diag port.- Connected QPST and QXDM- In QXDM's NV browers, i put '17592185995263' in both lines in NV item 06828 LTE_BC_CONFIG without backing up the original value (BAD DECISION, DON'T DO IT!)- Rebooted the phone, and now mobile network and wifi disconnectes every 5 seconds.What i have tried to fix this:1, Reconnect QPST and QXDM, now QPST doesn't read phone's ESN number, and QXDM is saying that i can read/write to any NV items. (Like in APN setting if it is blank or wrong apn it won't connect to the internet for ex and if press restore it will follow the sim default setup.) microchip is blank (need to delete or not just flash the new firmware using qpst (check if USB-Port is detected in pc and enable usb diag on your phone) so you can flash the firmware directly to the network microchip not gonna work if USB-mode is mtp) and it will restore automatically, restoring it manually by input numbers or binary conversations is the hardest way and illegal - check if the imei no. Because this is integrated first to the chip even without a buckup it will revert back to its default setup modem file, by downloading new network firmware in the error couse by the new modem1&2 file in the net. I think you can still restore your original baseband default,imei etc.

Don't modifying baseband and imei information, this are hardware built-in and hardware chip limitation, software has nothing to do with it, even if you successfuly unlocked those baseband channels, still not gonna work because of missing signal circuits inside the integrated cuircuits(IC).
